Europa: The Link Between OOL and SETI 09/30/2006
Why would searchers for extraterrestrial intelligence be interested in Europa?
After all, despite the movie 2010 command to attempt no landings there,
no astrobiologist believes it could host anything more than primitive life
certainly no one who could send messages to us.
Cynthia Phillips, a principal investigator for the SETI Institute,
explained the connection between origin of life studies and SETI in an article
Starting work on a Europa mission now, as suggested by the Solar System Exploration Roadmap,
is the right thing to do. Europas interior ocean may be the best environment for
life in the solar system beyond planet Earth. There is a substantial scientific basis
to believe that Europa has the fundamental ingredients necessary for life: water, organic molecules,
a chemical energy source, and a stable environment. Understanding Europas potential for
life brings us closer to addressing one of the most fundamental scientific questions that humans
can ask: Are we alone in the cosmos? It is only by committing the time and resources to a
capable Europa mission that we will be able to begin to answer this essential question.
The Lunar and Planetary Institute recently issued its
Solar System Exploration Roadmap, suggesting missions that NASA should consider for the next 30 years.
It focuses on the theme of habitability, indicating the importance that the search for life
has in the minds of planetary scientists. Not surprisingly, a Europa orbiter is one of the
flagship missions in the plan.
Notice the assumptions implicit in her answer. Cynthia
Phillips, like most astrobiologists, believes that environment produces life. Provide
water, heat, stability and organic molecules, and these are not only necessary conditions for
life, but sufficient ones as well. A second assumption is that life not only emerges
from suitable environments, but evolves into complex life, and then to sentient beings who
can communicate with us. These are assumptions, not scientific demonstrations; in fact,
they are contrary to good lab science. The only thing about these assumptions
demonstrated in the lab is their falsification.
Paper View: Evolutionists Augur Genes for Tales of Eyes, Hearts, Brains
SETI and OOL people should never assume that finding life on another world
will disprove religion. Many theologians for millennia have anticipated finding life beyond
the Earth. Indeed, in the 17th and 18th centuries, it was uncommon not to believe in
it. The same debates over whether natural forces alone are sufficient to produce
specified complexity will go on if life is found. Only the location will change.
Most likely, Europa, Titan, and Mars will all prove a disappointment. The debate is
too important to delay for 30 years to look at Europa.
Evolutionists need to engage this debate on Earth and not displace it to a distant world.

Origin of Life
The Sept. 29 issue of Science includes a special section on evolutionary genetics,
beginning with an overview by Barbara R. Jasny, Elizabeth Pennisi and John Travis entitled
Our organs tell stories. A pathologist, for example, can look at a lung and recognize
a lifetime of toiling in a mine. Our genes tell stories, too. By comparing the
genomic sequences of an ever-increasing number of organisms, we are now uncovering how our
bodies came to be the way they are. Evolution, it seems, is a tale of détente: The
need to adapt to changing environments is in a tug of war with the demand for precisely
functioning biological machinery. The stories presented in the special section
(and the graphic, p. 1912) emphasize different facets of this complex saga. They are
not just historical lessons; they have implications for understanding disease mechanisms as well as basic physiology.
Its not quite clear who is telling the tales, though the genes or the evolutionists
when they make comments like the next sentence: When it comes to the story of the human brain,
we are still stuck on the preface. It becomes apparent when looking at the other five
articles in the series that the bulk of the story is not in the genes, but in the imaginations of
scientists committed to evolutionary explanations....

Darwinism and Evolutionary Theory
Why Are Kids Hyper? Blame Evolution
Jon Hamilton on National
Public Radio was curious why his 7-year-old kid always had more energy than he did and
didnt need coffee to get him going. So he asked an evolutionary biologist at UC Irvine
and got the following explanation:
Its fairly clear that human evolution has been strongly shaped
by very powerful selection pressures over the last two million years to build
a bigger brain, Rose told me.
Makes perfect sense, doesnt it? Hamilton got a bonus from another evolutionary
biologist, Steven Lima (Indiana State) who explained that without parents, kids would not survive a
world of big cars and big cats:
That bigger brain doesnt have much in it when were born, Rose
says. So children need all that energy to explore the world and devour information.
Play and activity and doing all kinds of things including things your
parents and teachers dont like is a big part of developing a functional human brain,
Brain development pays off in the long run. Kids eventually get smart enough
to survive on their own.
But while theyre going full speed through childhood, they put themselves at
risk. So evolution has equipped children with parents who are slower but perhaps wiser.
They spend a lot of time rough-housing, running around screaming and all this sort of
thing, he says. This is one of the most ridiculous things you can do.
Its a giant Eat at Joes sign, you know. Just come kill me.
Im running around and not paying attention and making a lot of noise.
This evolution, its so wonderful, it even explains grandparents. A consequence of
not taking as many risks is living long enough to influence the next generation:
Parents are much more alert to danger, even if were not very perky.
So we keep an eye out for things like tigers and traffic.
And eventually, Lima says, children grow up and start acting more like parents.
Playing around like that becomes ridiculous, he says. You
dont get anything out of it anymore. It just becomes dangerous.
What slips away, of course, is youthful energy.
Fifty- and 60-year-old humans can be very relevant to the future of their offspring and
grand-offspring, Rose says. And for that reason, natural selection may indeed
still have some force in keeping us alive in middle age.
Provided, Hamilton quips, we dont fall asleep on the job.
And with that line, we award Stupid Evolution Quote of the Week
to Rose, Hamilton and Lima, for their flexibility to explain everything, even your morning coffee
and grandparents, by evolutionary theory. Funny that this didnt seem to work the
same way with deer children, who will sit quietly in the thicket while their energetic parents
are up and about. Isnt it amazing that evolution produces organisms that scream
for predators to come and eat them, and others that silently blend in with the background.
Evolution is so powerful, it even produces reason, and wisdom! (but not the ability to stay
energetic when you have the wisdom to use it).
Tarantula Spins Silk from Feet
Does anyone doubt that if the observations were reversed (parents more energetic
than children), these evolutionists would have another obvious, intuitive and confident
evolutionary explanation ready to serve up? It would never occur to these people that
other explanations might exist, like design. It doesnt matter to them that opposite
observations can be accommodated with their Silly Putty law of natural selection, the dream
gadget that does everything.*
What an elegant, beautiful system emerged in 1859, all from the fertile brain of a man
whose brain emerged by nature to pronounce truths about nature. You gotta admire Charlie

Darwinism and Evolutionary Theory
*...but nothing very well.
Surprise: a Costa Rican tarantula can spin silk from the tips of its feet.
A team of German and American scientists writing in Nature1 coaxed
one of these heavy, hairy spiders to walk vertically up glass, and was astonished to
find it ejecting silky threads that arrested its slipping and enabled it to cling.
They thought that these spiders only used the dry-attachment method that takes advantage
of intermolecular van der Waals forces, or the use of hooks on the feet. This discovery
of a third method of attachment was unsuspected, they wrote:
We induced A. seemanni to walk on vertical glass surfaces in order to observe
the contact mechanics of this challenging locomotion. When walking up vertical planes,
the spider attached only the distal parts of its tarsi to the substrate.
As it started to slip down the glass, silk produced by the tarsal spigots on all four
pairs of legs arrested the spiders descent and allowed it to remain attached
to the vertical surface. The spiders feet were positioned such that the
silk-producing spigots were in contact with the glass, while the dense setae in
adjacent regions were held off the surface.
The silk material appears similar to that produced by the spinnerets on the abdomen.
The finding made them wonder how this came about: Our discovery of secreted tarsal silk forces a reconsideration
of the evolution of spider silks, they speculated. Did the foot organs come first, followed
by the abdominal spinnerets, or vice versa? Both evolutionary hypotheses are
consistent with the homology of legs and spinnerets as arthropod appendages, they
Regardless of whether tarsal silk production is ancestral or secondarily derived,
the silk-producing apparatus of spiders seems to be controlled by developmental
modules that can be expressed in a variety of body parts.
The writeup on National
Geographic took up on this speculation that silk first evolved as an attachment mechanism for
the feet, and later evolved for web spinning. This, however, requires explaining how only tarantulas
retained the original function. The article ended with an Oxford scientist noting that protein
(of which silk is made) is not cheap for the spider. Even if you use very little, it
still costs energy, and energy is the animals money, he said. So why put
it in the feet unless you really need it?
Investigation of the genes involved in tarsal silk production should resolve
whether the original function of spider silk was to increase traction or
whether it was later co-opted for that purpose. Spinneret silk proteins are
encoded by a gene family that has evolved through a series of gene duplications and
subsequent modifications for particular tasks. If tarsal silks belong to the same gene
family, then comparison of tarsal and spinneret silks should help our understanding of
the ancestral function and composition of spider silk.
See also the Live Science
writeup on this story, where a scientist was completely surprised to find spiders
can do this, commenting, This research is a great example of how much there is still to
discover in the world around us. The article contains a brief description about
how abdominal silk is produced, and a table of interesting facts about tarantulas.
1Gorb et al., Biomaterials: Silk-like secretion from tarantula feet,
443, 407(28 September 2006); doi:10.1038/443407a.
Do we really need to spin an evolutionary tale about this?
The authors do not know how the intricate machinery for spinning one of the worlds
ideal materials evolved at all, let alone whether it evolved first on the legs or abdomen.
Heres another example of forcing observations into a reigning paradigm.
The facts merely show that these spiders are exquisitely endowed for coping with
a variety of situations they might encounter. Remember that a gland is an organ,
and an organ is a collection of tissues with a function, and that tissues are made of
specialized cells. It is naive to envision a whole collection of specialized parts
coming into existence simultaneously by some blind process of evolution. Realize, too, that it not only
takes the equipment, but the know-how and reactions to use it. The spider brain
also must have software to quickly turn on the silk production in the feet and simultaneously
retract the setae. How many millions of years did that take to get all this right?
Atheist Dilemma: Fight or Smooth-Talk Religion? 09/25/2006
Instead of getting distracted by some evolutionary tall tale, focus at
the design in these amazing spiders. Look at the handsome markings, the complex
eyes, the coordinated walking movements, and all the other structures and functions that
come together in a single complex animal that can carry on life in its niche and
reproduce all the parts for the next generation. Did you know a female tarantula
can live 20 years? These critters have defensive mechanisms that rightly cause us a little
trepidation (often exaggerated), but are really quite attractive creations in their
own right. Imagine designing a robot this capable. Science should discover, describe
and seek to understand the workings of nature. Fitting the observations into
speculations about origins is a job for philosophy and theology, not Nature.
Next headline on:
The unpopularity of evolutionism and the persistence of religious faith has scientific materialists confounded and dumbfounded
over how to respond. Some want to fight, some want to shrug it off, and some want to
dialog with religious believers, in hopes of convincing some of them that evolution is not
the bogeyman they think. Richard Dawkins is known for the intensity of his
rhetoric against all religion. His strategy is to take no prisoners, but condemn
religion as the opiate of the masses, an evil that must be opposed with militant energy.
The NCSE, on the other hand, plays the line that you can be religious and
still believe in evolution. Eugenie Scott, an atheist, has even produced Sunday
School material to soften the opposition (01/14/2002).
According to Kenneth Silber, writing for
Tech Central, the AAAS has
also entered this arena with a new book entitled The Evolution Dialogues: Science,
Christianity, and the Quest for Understanding:
The book, published by the American Association for the Advancement of Science (AAAS), is
an unusual offering for a scientific society in its focus on religious issues.
Targeted especially at Christian adult-education classes, The Evolution Dialogues
contributes a thoughtful discussion to the highly charged debate about evolution and its
implications. Written by Catherine Baker and edited by James B. Miller, the work
was developed with input from scientists and theologians.
These approaches attempt to woo the faithful into acquiescent acceptance of evolution (with acceptance
of evolution as the unalterable goal). Such tactics usually work only with liberal churches.
Last Februarys Darwin Day (02/11/2006) found willing ranks
of liberal pastors ready to preach from the Origin of Species.
Perhaps the oddest attempt in this vein recently came from
admitted apostate Michael Shermer, leader of the L.A. Skeptics Society, writing for
American. He argued that Christians should embrace evolution because it is good
theology, while creationism is bad theology. Not only that, Shermer argued that
evolution fits in with the political and moral values of the religious right.
It is not likely Pat Robertson and Jerry Falwell will be convinced. They might
even turn the argument back on Shermer and ask why he is a liberal, if conservatism
is more adaptive.
There are also some, like Ronald Numbers, who may not agree with believers
but believe their views should be taken seriously and treated with respect.
More commonly, Darwinist materialists seem content to explain away religion as
an evolutionary artifact. An example is Daniel Dennetts; new book
Breaking the Spell: Religion as a Natural Phenomenon (Viking, 2006), reviewed
by Kim Sterelny on American
Scientist, by Jack Miles in the
Post, and mentioned in a
Newsweek article by Jerry
Adler about modern atheists. Encompassing religion in a Darwinian worldview is the
strategy likely to be endorsed by the mainline science
journals. Though, according to reviewer Sterelny, Dennett devotes much of his energy
to trying to convince his nonsecular readers that it is legitimate to inquire scientifically
into the roots of religious belief and to assess its moral consequences, good and bad,
in the end, Sterelny thinks His intended audience will rightly regard any evolutionary model, indeed
any secular model, of religion as essentially corrosive. Thats because
Dennett believes that religion evolved; it is not a response to anything real in the divine
realm, but is only an artifact of material causes acting by natural selection.
Atheism, by this measure, is not in the dock.
Typically, the evolution of religion theorists use cognitive
neuroscience and game theory to describe religion, altruism and other behaviors as
adaptive strategies among populations of organisms (in this case, people) needing to preserve
their genomes. The more sensitive of the bunch, like Dennett tries to be, attempt to explain
the persistence of religion (for their atheist colleagues) on one hand, but try to assuage
the fears of believers, on the other hand, that Darwinism does not necessarily lead to a
dog-eat-dog moral chaos. They try to attract believers to the beauty of evolutionary
theory, and its advertised ability to explain peacock behavior as well as our own.
Some, like Dennett, even try to calm the battlefield by persuading fellow atheists to learn
more about religion. Miles finds this somewhat hypocritical, though: though
Dennett pays lip service to the need for Darwinian theorists of religion to acquaint themselves
with actual religion as patiently as Darwin acquainted himself with actual animal breeding,
in practice he rarely does so.
Though Dennett tries to be more nuanced, cautious and soft-spoken than Dawkins,
Sterelny argues, he is really a close ally to Dawkins, who along with Richard Harris, Adler
remarks, uses bone-rattling attacks on what they regard as a pernicious and outdated
Apparently religion-by-evolution is becoming a popular vacation topic.
Dennett will be the featured speaker at a conference in Hawaii next January
on the subject, The Evolution of Religion.
There must be an adaptive benefit for this new trend among atheists.
Sad. If Dennett, Dawkins and Harris really believed
and understood what they are arguing, they would realize that they are shooting themselves
in the feet. If belief in God evolved as an adaptive strategy, and therefore has no
validity in its claims, the same can be said for belief in evolution indeed, for
belief in anything. It would make just as much sense for other Darwinists to
explain Dennetts behavior in evolutionary terms, and for him to fight back and explain
theirs in evolutionary terms, till everyone sings, Ashes, ashes, we all fall down.
Deep Field Survey Shows Oldest Galaxies Yet
Speaking of cognitive neuroscience,
Dennett has a bad case of what we will term the Yoda Complex. He makes
himself out to be some kind of exalted master, the Enlightened One,
like some disembodied green god with pointy ears (and a pointy
head), able to talk down to the rest of humanity. In reality, he wears flesh and bones and puts
on pants like the rest of men. Most of us wouldnt promote a guy like him to Exalted Master if we
could. But Dennett rambles on like some Yoda, sipping a soda in his pagoda, as if we
owed assent (or a cent) to his ode. (A girl named Rhoda showed a more rational
response to the evidence than some believers:
While Dawkins recklessly swings his light saber like the dark lord of the Mith, Dennett
talks smooth and deliberately in hushed tones, unaware that the universal acid that flowed away
from his own Darwinian principles was strong enough to corrode a Darwinist container, too.
In case any Ewoks out there are entranced by Yoda Dennett, as if he showed a thing
or two from some enlightened abode, a perceptive mind will know whats up.
Thats because Yoda wrote a coda to his ode,
a line in the review to his book on Amazon.com where he spilled the beans (or his guts,
if theres a difference): I appreciate that many readers will be profoundly
distrustful of the tack I am taking here, he said. They will see me as just
another liberal professor trying to cajole them out of some of their convictions, and they
are dead right about thatthats what I am, and thats exactly what I am trying
to do. So, students, now that he has shown his true colors, what side of The Farce
is he on? (answer: 06/20/2003).
One doesnt have to be dead right. Being alive and right is much preferable.
Keep reading Creation-Evolution Headlines, where you learn how to explode
a load of phony openness before youre snowed. A pretentious Yoda in his own mind,
Daniel Dennett showed a code of bluster, not a display of wisdom bestowed upon him from on high.
A man he is, pretender he is; deceitful times, these. You asked for it, you got it: Toy Yoda.

Astronomers continue to find mature galaxies at higher and higher redshifts.
The latest record, reported in Nature,1 is z=6.96, interpreted to mean
the galaxy was present 700 million years after the big bang (usually dated at 13.7 billion
years ago). A survey of distant galaxies from the Hubble Ultra Deep Field (HUDF), also
reported in Nature,2 found 500 galaxies at z=6 (assumed 900 million years after
the big bang) but only one candidate at z=7 to z=8 (700 million years). They interpreted
this to mean, The simplest explanation is that the Universe is just too young to have
built up many luminous galaxies at z approximately ~7-8 by the hierarchical merging of small
galaxies. Are we, therefore, peering into the dark ages before the
dawn of galaxies? Richard McMahon, commenting on these studies in the same issue of Nature,3
noted that the HUDF study was restricted to an extremely narrow portion of the sky, so better
instruments and more observations will be required; Only then will the presence, or absence,
of further galaxies be able to tell us whether we really are homing in on the era of reionization.
This story was noted by Space.com,
Geographic; a press release is available on the Hubble
Space Telescope site. The European
Space Agency press release includes pictures of the Hubble Ultra Deep Field survey, including
a dramatic animation zooming in from a wide star field to the very narrow spot where one of the
distant galaxies was discovered. The findings also show that these dwarf galaxies were
producing stars at a furious rate, it says, about ten times faster than is happening
now in nearby galaxies. The Hubble press release states,
Astronomers had not seen even one galaxy that existed when the Universe was a billion years old,
so finding 500 in a Hubble survey is a significant leap forward for cosmologists.

It must be remembered that things like starbirth rates and
galaxy formation timelines are inferred from theory. The observations show only colors,
luminosities and chemical compositions of objects, along with other properties of spectra.
The shift of certain absorption lines from their normal wavelength positions is interpreted as
universal expansion, except by the maverick astronomers (12/06/2004).
Even assuming the standard big bang scenario, though, it is a huge
lumpiness problem for cosmologists to find galaxies already formed and producing stars at
prodigious rates so near the beginning. The sample sizes
have been very limited so far. Already, though, it is very surprising to think that
whole galaxies could appear so soon out of a sea of particles by natural causes
(05/11/2006). Watch for new records
to be set in future surveys.
Mars Radiation Would Fry Astronaut Brains 09/23/2006
Next headline on:
Imagine the first Martian astronauts coming home confused, impaired and demented.
This is the risk from solar radiation on Mars, say a group of NASA
medical researchers (see RxPG News).
Among the gravest risks of a manned flight to Mars ranks the possibility that
massive amounts of solar and cosmic radiation will decimate the brains of astronauts,
leaving them in a vegetative state, if they survive at all.
The kinds of radiation astronauts could be exposed could be like that from a nuclear disaster,
one of the researchers said, because, The sun is basically a big nuclear reactor.
Though we are much closer to the sun, we are shielded on Earth by the atmosphere and the
Van Allen Radiation Belts which Mars lacks.
Dubbed Risk 29 by NASA's Mars scientists, the cosmic radiation risk
remains a show-stopper because shielding a spacecraft from all radiation could make it too
heavy to reach Mars, which, at its closest, is 38 million miles from earth.

Earth, passed away last month at the age of 91

Was Archaeopteryx a Biplane? 09/22/2006
Next headline on:
A U of Calgary
PhD student thinks Archaeopteryx flew on all fours. Nick Longrich thinks the early
bird had feathers on its legs that gave it additional lift. The discovery of some Chinese
fossil birds with feathers on the legs lends support to his interpretation, he says.
The idea of a multi-winged Archaeopteryx has been around for more than a century,
but it hasnt received much attention, Longrich said. I believe one reason
for this is that people tend to see what they want or expect to see.
Everybody knows that birds dont have four wings, so we overlooked them even when they
were right under our noses.
He thinks this argues for the
tree-down (arboreal) theory of the origin of flight, instead of the ground-up (cursorial) theory.
Maybe Longrich should dial Ken Dial down in Montana for his opinion.
Dial has staked his reputation on wing-assisted incline running (WAIR) for the origin of flight
(see 05/01/2006, 11/16/2005,
12/22/2003, 01/16/2003), so
this is likely to spoil his spoilers. But were all for peace.
Working toward consensus is a buzzphrase these days. Maybe by working together
they can come up with an even better story. The wingless female was diving off the tree,
you see, and the wingless male, arms outstretched, came running to catch her.
Bacteria Generate Hydrocarbon Reservoirs
If Archaeopteryx had four functional flight surfaces instead of two,
thats not evolution. For structures to persist, they have to help an animal survive.
Incipient structures do not help survival; they only get in the way. If some extinct birds
had more aerodynamic equipment than birds today, it indicates something has been lost, not gained.

These heavy energy-rich hydrocarbons may be widespread in ocean sediments. The authors of a paper in

larger than methane derive only from thermal degradation of fossil organic material.

propane specifically, this surprise announcement includes the possibility that heavier hydrocarbons
could be formed by processes not yet understood. The end of the paper says cryptically,
Specifically, they signal the presence of an additional process, probably significant in
many environments, for extending the terminal degradation of organic material.

Farewell to the Face on Mars A Teachable Moment
Next headline on:
Express orbiter has just sent back pictures of the Cydonia region on Mars. Objects
seen in early Viking images of this region resembled a face, a skull and pyramids that gave
rise to a cult following on late-night talk shows. NASA always discounted
these resemblances as coincidental, and when JPL released higher-resolution photos from the Mars Global
Surveyor (05/24/2001) it seemed to settle the matter.
The latest high-resolution color photos, showing the view from oblique angles, should put to
final rest any speculations that intelligent aliens made the features as monuments.
Late night talk show hosts and their so-called experts

design that isnt there, or accuse the European Space Agency of conspiracy to fudge
the data. This is the power of belief in spite of evidence. To show our good will,

Teachers, however, can use this episode as an example of design detection principles.
We all tend to see faces in natural phenomena, but most of the time, we can usually tell when
something was designed or not. Compare Vermonts erstwhile
Old Man of the
Mountain with Mount Rushmore. This can be a
fun project. Finding images on the internet is easy with search engines.
Assemble as many lookalike images as you can and give children a test to
see if they can tell which were designed, and which were due to natural causes or chance.
For each picture ask, Designed or not designed? Explain, That covers all the possibilities,
doesnt it? Either something was put together on purpose [by a mind] to say something or to do
something, or else natural causes were sufficient to explain it.

The research team has been gently extracting the
pieces of bone from cemented sandstone for five years. They submitted their initial paper in for
publication in April, but estimate it will take several more years to extract remaining fragments from the matrix.
Based on tooth morphology, they estimate
this specimen to have been a 3-year old female. Because of the species affinity with Lucy
(though found some 10 km from Johansons famous fossil), some are nicknaming this skeleton Lucys baby
(but the discoverers have nicknamed her Salem, peace).
The skeleton from the waist up is very ape-like, indicating a life in the trees, they claim.
Though more complete than previous A. afarensis fossils, it lacks the pelvis;
only a foot, pieces of leg bones, kneecaps as small
as a dried pea provide anatomists with evidence to claim she walked upright one of
the most contentious parts of the debate over the older Lucy fossil.
The authors indicated that several parts of the skeleton have been distorted in the
burial process: The cranium is intact except for parts of the frontal squama and significant
parts of both parietals, which have broken away to reveal the complete natural brain endocast (Fig. 1d),
the paper states. The back of the calvaria is slightly distorted, pushing the nuchal region
forward (Fig. 1f). Later, The articulated postcranial elements in the primary
sandstone block include both scapulae and clavicles, the cervical, thoracic and the first two
lumbar vertebrae, and many ribs. They are displaced from their original anatomical positions,
and are compressed superiorly under the cranial base and the palate, making preparation difficult (Fig. 1b, c).
The scientific papers, furthermore, tend to be less dogmatic than the press releases.
The authors only say that this skeleton resembles Lucy, and are tentative about the age,
which the popular press state confidently as 3 years old. Furthermore, the authors understand
that interpretations of life habits based on bones is not an exact science:
Now that the scapula of this species can be examined in full for the first time, it is unexpected
to find the strongest similarities with Gorilla, an animal in which weight-bearing and
terrestrial knuckle-walking predominately characterize locomotor use of the forelimbs.
Problematic in the interpretation of these findings is that the diversity of scapula
architecture among hominoid species is poorly understood from a functional perspective.
Most surprising, this specimen was apparently
buried suddenly in a watery flood along with many other animals:
This depositional setting, combined with the remarkable preservation of many articulated
faunal remains lacking evidence of preburial weathering, most likely indicates that the
juvenile hominin was buried as an intact corpse shortly after death during a major flood event.
This is echoed by Wynn et al. who, in the same issue of Nature,2 described the
geological setting of the fossil:
This depositional setting, combined with the remarkable preservation of many articulated faunal remains
lacking evidence of preburial weathering, most probably indicates rapid deposition during major flood events,
burying many fossils as intact corpses (including the juvenile hominin).
In the vicinity of the skeleton were found bones of catfish, mouse, rat, monkey, baboon, mongoose,
elephant, extinct horse, rhino, hippo, pig, bushbuck, giraffe, antelope, impala, gazelle, crocodile,
coral snake, tortoise, and other animals.
In the same issue of Nature,3 Bernard Wood called Lucys baby
a precious little bundle. He agrees, The corpse of the infant was buried more or
less intact, and the sediment in flood waters must have swiftly covered it. As to this species
ability to walk upright, Wood is equivocal:
There remains a great deal of controversy regarding the posture and locomotion of A. afarensis.
Most researchers accept that it could stand upright and walk on two feet, but whether it could climb
up and move through trees is still disputed. Some suggest that its adaptations to walking on two feet
preclude any significant arboreal locomotion, and interpret any limb features that support such
locomotion as evolutionary baggage without any useful function. Others suggest that a primitive
limb morphology would not have persisted unless it served a purpose.
Wood leaves any complete understanding to the future. After exploring several questions this fossil
opens, he ended, Whatever the answers to such questions, the Dikika infant has the potential to provide a wealth of information about the growth and development, function and taxonomy of A. afarensis. He
told Associated Press that this find wont settle the debate among scientists,
which he said makes the Middle East look like a picnic.

On the other hand, Carl Wieland, a creationist with
Creation Ministries International,
considers this good news. The more complete skeleton confirms what critics have alleged for years, that Lucy was a
tree-climbing, knuckle-walking ape that did not walk upright.

When you scrape away the hype and artistic license, most of the details of the
actual bones seem to back up criticisms by creationists that this is nothing more than an extinct ape.
The only portions of the skeleton that evolutionists use to claim this creature had something to do with
human evolution are the least preserved: the leg and foot bones. They interpret these to mean it walked upright, as
if walking upright is the main human distinctive. The best-preserved parts of the skeleton, by contrast,
are clearly ape-like and argue against this extinct ape being a walker. Read the articles skeptically, without
assuming what the evolutionists assume, and the evidence is profoundly unconvincing for the claims
made about it. Everything from the backbone up is well within the charts for an ape, not
a human wannabee. The paleontologists admitted, also, that the skeleton has been deformed;
how does that affect the interpretation, when assessing function from structure is poorly understood
under the best of conditions?
Farewell, Cannibal Dino
This fossil also creates other problems for the evolutionists.
Consider, for instance, how the evidence for arboreal (tree-climbing) behavior, based on the fingers
and shoulder blades, scrambles the Lucy story: The foot and other evidence from the
lower limb provide clear evidence for bipedal locomotion [sic], but the gorilla-like scapula and
long and curved manual phalanges raise new questions about the importance of arboreal behaviour
in the A. afarensis locomotor repertoire. This means that evolutionists must now either
consider the tree-climbing equipment as evolutionary baggage or believe that this
creature climbed trees half the time and walked upright the other half. (Only human boys
exhibit this behavior today, but they quickly grow out of it.) If Darwins mechanism
could produce instant phyla at the Cambrian, why couldnt it get rid of its baggage just
as quickly? On the other hand, if Baby Lucy was happy in the treetops, why was there
evolutionary pressure to make her strut on the ground, when other primates found buried with her did not
feel the same pressure? And how can minorities endure the racism implicit in the artwork
that always shows these alleged primitives with dark skin?
The Darwin Party baby shower for Salem is, therefore, highly overblown,
as is usual for human-evolution celebrations. They dont seem to be focusing quite as much on the
remarkable collection of animals buried with the little she-ape. If a sudden flood of this
magnitude occurred today, burying this many animals in the same graveyard all at once, wouldnt
it be international news? This was not a volcanic landslide; it was a watery catastrophe.
Notice how much the media are going out of their way to characterize this ape as a child and
a baby when they wont even afford that dignity to a human embryo.
It is time to get rid of the evolutionary baggage and discover the real

Incidental to the article is a tidbit some may find astonishing:
hundreds of specimens were found buried together in north-central New Mexico back in 1947.
A whole group of animals had died en masse in some catastrophe.
Yes, ideas need testing. Sad to say, nobody appears

two generations of scientists focusing more on the diet of Coelophysis than on the
amazing fact that whole populations of these creatures died together in some
catastrophe. Some catastrophe, indeed.

Genetic Toolkit Manages Dangerous Tools with Safety Switch and Lockbox
Next headline on:
Laymen appreciate scientists who can express complex concepts in everyday terms.
Heres a good example from the Wistar
Around the home, regularly used tools are generally kept close at hand: a can opener
in a kitchen drawer, a broom in the hall closet. Less frequently used tools are more
likely to be stored in less accessible locations, out of immediate reach, perhaps in the
basement or garage. And hazardous tools might even be kept under lock and key.
The article discusses how researchers at Wistar Institute found a two-molecule complex that
governs how the chromatin that packages DNA will become either loosely organized or tightly
condensed. Some unknown switching mechanism determines how ASF1 will bind to one of
two similar molecules, HIRA and CAF1, that determine the degree of tight packing:
Similarly, the human genome has developed a set of sophisticated mechanisms for
keeping selected genes readily available for use while other genes are kept securely
stored away for long periods of time, sometimes forever. Candidate genes for such
long-term storage include those required only for early development and proliferation,
potentially dangerous genes that could well trigger cancers and other disorders should they
be reactivated later in life.
An unanticipated observation from the study centers on the region of association between the
two molecules in the complex. The researchers knew that one of the two molecules in
the complex, called ASF1, associated with a particular molecular partner, HIRA, when directing
assembly of the more condensed form of chromatin. But it could also associate with
a different partner, called CAF1, to shepherd assembly of the less condensed form of chromatin.
However it works, its important: one researcher explained, Appropriate packaging of the
DNA in the cell nucleus is crucial for proper functioning of the cell and suppression
of disease states, such as cancer.
The research has been published online in Nature Structural and Molecular Biology.1
On closer study, the scientists discovered that HIRA and CAF1 have nearly identical
structural motifs in the regions of interaction with ASF1. This means that ASF1 can bind
to one or the other molecular partner, but not to both. In other words, the interaction
is mutually exclusive: A kind of decision is made by ASF1 as to whether to guide the assembly
process towards the more or less condensed forms of chromatin. What determines the choice?
The relevant factors are unknown for now.
1Tang et al., Structure of a human ASF1a-HIRA complex and insights into
specificity of histone chaperone complex assembly,
and Molecular Biology, Oct. 2006, published online: 17 September 2006; doi:10.1038/nsmb1147.
Good work, by scientists operating on design principles (whether
they realize it or not). There was no mention of evolution in the press release. It would
would seem, also, that evolutionary theory would be useless in tracking down the factors that determine
which binding takes place.
Marine Mimics Found Off Thailand
You might not have realized that your genetic toolkit has power tools that

locking up its dangerous equipment. Most of the trillions of cells in your body get it
right for decades, and even when theres an accident, the body has other procedures for
containing the damage. It is mind-boggling that all this goes on without our conscious

Apparently the shark can swim with its fins, but has a habit of walking along the
reef surface. Biologists studying these sharks suggest they could serve as models
for the first animals that moved from marine environments onto land, the article says.
Think of the wonderful new possibilities this opens
up for evolutionary storytelling. The shark is obviously practicing for its
eventual debut on land. And shiver me timbers, shrimp must have retained
developmental genes shared by praying mantises, leading to a most remarkable case of

If nothing else, the scientific investigation of Neanderthal Man is valuable for illustrating
how fluid scientific opinion can be. Since we found out Sept. 1
that Neanderthal genes may be lurking among us, two more unexpected claims have been made about
these wrestler-build members of genus Homo.
Some may think the only scientific law being confirmed here is Dykstras Law:
Everybody is somebody elses weirdo. Another pointed out that finding cave men
does not prove evolution. We still have cave men today Osama bin Ladin.
- Hideouts and Holdouts: Some Neanderthals may have lived thousands of years
longer than earlier believed, said Live
Science, Science Now
Geographic. This controversial claim emerged from radiocarbon-dates of
charcoal from a Gibraltar cave as recent as 24,000 yearssome 6,000 years earlier
than the standard 30,000-year mark when modern humans were said to become dominant.
BBC News has a picture
of the cave and the locale. A possible multi-thousand-year overlap resurrects the
question of whether Neanderthals and modern humans interbred. Skeptics dispute the
dates, claiming the samples must have been contaminated.
- Im OK, Youre Strange: Erik Trinkaus of Washington State got publicity
with this assertion: Neanderthals were normal; its we modern humans that are strange
(see Live Science).
He compared other members of genus Homo and discovered that modern humans
have twice as many uniquely distinct traits as Neanderthals. Whether that
qualifies as making us weird might be debated, but Trinkaus argued, In the broader sweep
of human evolution, the more unusual group is not Neanderthals, whom we tend to
look at as strange, weird and unusual, but its us, modern humans.
Did we hear a scientist doubting the accuracy of
radiocarbon dates? Is it possible somebody is picking and choosing the dates
they want? Evolutionists want us to believe that Neanderthals did little more
than hunt game and paint on cave walls for 70,000 years, even though their average
skull capacities were larger than ours. Does that make any sense?
Whats Inside a Spore? Nanotechnology 09/17/2006
Though Neanderthals (whatever we call them) are classified according
to a set of distinctive anatomical traits, there is more variability among living people
than between average Neanderthals and average modern humans.
Could Neanderthalism be nothing more than an artifact of human classification bias?

conception that accentuates the primitive look. This harks back to
Haeckels ranking of humans to make certain races look less evolved.

They are actually a benefit; they allow larger muscle attachments for chewing.
It could be argued that we modern humans are at a disadvantage without them.
Any trait can be accentuated in a limited gene pool; look at dachshunds vs. huskies. You could
organize dogs into groups based on traits, and set arbitrary boundaries between the

The spores that are emitted from fungi and ferns are so tiny, the appear like dust in
the wind. Who would have ever thought such specks could exhibit nano-technological wonders
like scientists have found recently:
In the second article, the researchers found that a similar compaction method works in the sperm cells
of animals as diverse as fruit flies and mice. To them, this observation is
suggesting that the mechanisms governing genome compaction are evolutionarily ancient,
highly conserved in species whose lineages diverged long ago.
- Evapo-Motors: Scientists at U
of Michigan were intrigued by how ferns turn the power of evaporation into launching pads.
The sporangia (spore ejectors) use a microactuator to eject the spores into the environment
as they dry out. The team was so impressed, they said Oh, we have to build that,
and imitated the mechanism to build microchips that open and close when wetted or dried. They
think they might be able to generate electricity without batteries with this technique.
- Info Compactor: Despite their minute size, spores must carry the entire
genome of the species. A Wistar
Institute press release talked about that. Its incredible: a histone tag on the chromatin
somehow signals a compaction process that reduces the already-tight fit to 5% of the original volume.
All this must be done very delicately, because spores are haploid (one strand of DNA) and much more
subject to disastrous breaks.
Can we just ignore that stupid little evolutionary piddle for a moment,
and enjoy the fascination of these observational facts? The ejection method of spores in ferns is just one of
many highly clever and diverse seed-spreading techniques in the plant kingdom, some of which also use
desiccation to advantage, like the Scotchbroom, whose pods explode to send seeds as far as 50 feet. A beautiful film
Journey of Life illustrates some of these tricks of the plant trade and is well worth watching.
Voles Throw Evolutionary Genetics Into Disarray 09/16/2006
In the second story, think of how delicate and accurate this process has to be.
In the quintillions of sperm and spore cells that are produced throughout the world, most of the
time the process works flawlessly. The article did not even mention that a reverse process
must also take place. Packing is one thing, but what if you cant unpack the information just as
delicately and accurately? Undoubtedly pollen grains have this nanotechnology, too.
A human cell can contain six feet of DNA, contained in the microscopic dot of a cell. Many plants
have even larger genomes. A seed, sperm or spore must contain not only the entire genetic code,
but the nutrients and machinery to unpack it, deliver it and protect it so that the next generation
of the species can continue. Could Darwin have known such things, one wonders how different the
history of science (and politics) might have been. Now, theres no excuse.

What is it with voles? These little gopher-like furballs with beady eyes, short tails and
tiny ears are giving evolutionary geneticists fits. A press release from
University states, Purdue University research has shown that the vole, a
mouselike rodent, is not only the fastest evolving mammal, but also harbors a
number of puzzling genetic traits that challenge current scientific understanding
and are an evolutionary enigma with many bizarre traits, videlicet:
Why is this an evolutionary puzzle? The study focuses on 60 species within the vole
genus Microtus, which has evolved in the last 500,000 to 2 million years,
the article says.
This means voles are evolving 60-100 times faster than the average vertebrate in
terms of creating different species.
- Chromosome numbers range from 17 to 64 between species.
- X chromosomes in some species carry 20% of the genome.
- Some females carry significant parts of the male Y chromosome.
- In some species, the males and females have different chromosome numbers.
- Despite widely variant genotypes, all voles come out looking basically the same (phenotype).
Some species look so identical it takes a DNA analysis to tell the difference.
It doesnt mean any such thing. It means, rather,
that evolutionists are more incorrigible than ever when faced with conflicting data, to the
point they will believe in miracles.

These findings also mean that geneticists dont understand nearly as much
as they thought. How can you have vastly different genomes that yield identical-looking
animals? What do genetic differences really imply about the fitness of individuals
and populations? Why would a little furball evolve 100 times faster than an elephant, monkey,

67 dinosaurs in a week: thats what diggers from

Most skeletons were Psittacosaurs, thought to be predecessors of the horned ceratopsids, like Triceratops.
Seeking to understand the developmental biology of dinosaurs, the team
was less interested in new species than lots of specimens of one species:
Horner wants a large number of fossils so he can compare variations between skeletons
and changes during growth.
The press release mentioned nothing specific about evolution, nor about how
these skeletons became buried in such large numbers. The one picture shows the hunters
working in an arid, desert environment that must be very different from the world in which
these dinosaurs perished. Lecture notes from

Imagine a peaceful herd of dinosaurs grazing by the lake bed,
then deciding to die en masse and cover themselves with sediments. If that does not

Evolutionary stories and timelines are not essential to

Those following the Titan exploration by Cassini-Huygens
have wondered where the ethane went. Oceans of ethane hundreds of meters deep, if not
kilometers deep, were predicted but not found, as reported previously (see

pre-Huygens reports, 01/15/2005 and
01/21/2005 Huygens early results, and
12/05/2005 review; see also
New Scientist analysis
of the total revolution in thinking about Titan going on because of the
lack of oceans). Now, finally, Cassini found something at least: a cloud
of ethane at the north pole (see
press release) Is it enough to blanket the embarrassment of finding Titan to be
a dry, young surface with only trace amounts of ethane?
The findings made by Cassinis Virtual and Infrared Mapping Spectrometer (VIMS)
were published in Science this week,1 and described in a Perspectives
article by Cassini atmospheric scientist Mike Flasar in the same issue of Science.2
Indeed, a vast tropospheric cloud of ethane was observed over the north pole in a series
of observations between Dec. 2004 and Sept. 2006 (this cloud contrasts with the south-polar cloud
believed composed of methane).3 The abstract leads one to believe this
solves the problem of the missing ethane:
The derived characteristics indicate that this cloud is composed of ethane and forms
as a result of stratospheric subsidence and the particularly cool conditions near the moons
north pole. Preferential condensation of ethane, perhaps as ice, at Titans poles
during the winters may partially explain the lack of liquid ethane oceans on Titans
surface at middle and lower latitudes.
That word partially is key, though, as shown in subsequent discussions in the paper.
First, they restate the problem in stark terms, to show the seriousness of the prediction that failed:
Methane (the second most abundant atmospheric constituent after nitrogen) is
dissociated irreversibly by solar ultraviolet light, producing primarily ethane
and, at one-sixth and one-10th of the ethane production rate, respectively, acetylene and haze,
as well as other less abundant organic molecules. These photochemical by-products precipitate
to Titans surface. Titans atmospheric composition and photochemical models indicate that ethane accumulates as a liquid (at the equatorial surface temperature of 93.5 K) at a rate of ~300 m (if global) over
Titans lifetime of 4.5 billion years, whereas solid sediments, including acetylene
and haze particles, accumulate at roughly one-third of this rate. Thus, unless
methane is a recent addition to Titans atmosphere or ethane incorporates itself
into surface solids, it has been reasoned that a considerable fraction of the
surface should be covered with liquid ethane. Titans surface reveals dunes
of solid sediments, probably including haze particles and acetylene ice. In addition,
the surface is riddled with alluvial features, suggesting the occurrence of methane
rain in the past. Craters are rare, indicating geological relaxation as well
as their burial by photochemical sediments. Yet Titan appears depleted of its most
abundant photochemical by-product. Except for the ethane-damp surface measured
by Huygens, no condensed form of ethane has been detected, despite its rapid production in
Titans stratosphere and the expectation of finding ethane-rich oceans before the Cassini encounter.
The same is admitted by University of Arizonas Lunar and Planetary Lab in a press release
Ethane is by far the most plentiful byproduct when methane breaks down, it
states. If methane has been a constituent of the atmosphere throughout Titans
4.5-billion-year lifetime -- and there was no reason to suspect it had not -- the
large moon would be awash with seas of ethane, scientists theorized.
Thats why most artist conceptions were amply illustrated with liquid before Cassini found
a dry desert (05/04/2006)
with a few possible lakes at high latitudes (07/24/2006).
The science team tried to get a fix on the composition of the cloud and the mass of ethane within
it from the four oblique views obtained by VIMS. Best guess by inferring spectral properties,
particle sizes and altitude is that the cloud is indeed ethane, that condenses at 30-50 km above
the pole and precipitates down, falling at 3 km per month. If conditions remain cool
enough throughout the year, they infer, Titan may accumulate ethane ice each winter
at the poles and develop year-round polar caps. Direct evidence of an ethane ice cap
will have to await future flybys by Cassini (perhaps the high-latitude pass on October 9).
What about the south pole, though, which has been imaged? No simple answers, unfortunately,
and well have to wait to find out, but what we know is not that convincing yet:
Presently, there is no direct evidence of polar caps composed of ethane.
The northern pole has not been imaged. Cassini images of the southern pole do not
indicate the morphology of 2 km of ethane ice, assuming current rates of ethane production over the past 4.5 billion years, accumulated within 35° of the poles. Yet south polar images suggest flow features,
possibly associated with a smaller quantity of ethane ice accumulated on the young surface.
The detection of surficial ethane ice is hindered by the correlation of ethane features and
methane signatures, which obscure the visibility of Titans surface. In addition,
the polar surface is probably distinct and varied. Similarly, other hydrocarbons
would precipitate preferentially at the poles and pollute the ethane ice, and any
lowland methane lakes would dissolve and melt ethane, because the mixtures
eutectic temperature is 72.5 K. Such lakes might condense out of Titans humid
lower troposphere during winter. The surface distribution of liquid or solid ethane,
whether corralled into the polar regions by circulation or transported
by surface flows to lower latitudes, will be determined with radar and near-infrared images
of the geomorphology, radio determinations of the polar temperatures, and infrared measurements
of the polar composition, which are scheduled for future Cassini encounters with Titan.
What does Dr. Flasar think of all this? His commentary focuses primarily on the atmospheric
circulation on Titan. At the end, his reference to this problem is delicately understated:
Until now, clouds of the most abundant product of methane dissociation, ethane, have
eluded detection. The Griffith et al. identification of polar ethane clouds
is reassuring, in that it validates the basic ideas we have about Titans meteorology and
chemistry: first, that condensation does occur, as expected, in the lower stratosphere,
and second, that the inferred altitudes of the ethane cloud (30 to 50 km) are consistent with
subsidence in the winter polar region. This and other clues that we will obtain will
help us to sort out the things we still puzzle over.
The biggest puzzle on his mind is, undoubtedly, where is all the ethane? Its not enough
to answer that it just stacks up at the poles. The U of A press release spoke with lead
author Caitlin Griffith, and reported, If ethane was produced at todays rate
over Titans entire lifetime, a total of two kilometers of ethane would have
precipitated over the poles. But that seems unlikely, Griffith said.
Why? The south pole, which should roughly match the north pole, shows no such ethane ice cap.

3Methane, CH4 is exposed to the solar wind in the upper atmosphere
of Titan, a continuous process that strips off hydrogen
atoms. The ionized methyl groups CH3- rapidly recombine into
ethane C2H6, which has nowhere to go but down. At surface
temperatures on Titan, it should condense as a liquid, or as ethane snow at higher latitudes
where it is colder. Extrapolating the current ethane production rate for the assumed age of
the solar system (4.5 billion years) should have yielded deep oceans of ethane at least 300 meters
deep, but probably much deeper if methane were more abundant in the past, as is commonly believed.
The problem vanishes when you liberate your mind from the
requirement of billions of years. This is really uncanny. Everything about Titan
screams young, but nowhere do you find anyone questioning the linchpin assumption that
Titan is 4.5 billion years old. Its almost like they want to downplay this
puzzle and sweep it under the rug. Dont let them. Most creationists
could live with a young or old Titan, though some would prefer the former. The only
people who would be completely scandalized by a young Titan are the evolutionists who absolutely
depend on billions of years in which to hide their skeletons.
Another Rotary Machine Found in Bacteria 09/13/2006
The ethane cloud is too little, too late. After all, vast quantities
of ethane must be there.
Dr. Flasar admitted it: he was reassured that the ethane condensation does occur and
that the basic ideas about Titans chemistry have been validated. It follows logically
that this process, going on interrupted for billions of years, would leave the evidence in
abundance. OK, so where is it? They cant hide the answer in the future much
longer. Imagine the entire globe covered with an ethane ocean half a mile deep or more.
What happened to it? Did the interior suck it up like a sponge? Did aliens take it?
Did creationists steal in a vast conspiracy to support their young-earth views?
Come on; let the facts speak to the unbiased mind.

A molecular garbage disposer in the cell membrane bearing some resemblance to
the rotating motor ATP synthase has been described in Nature.1
This machine, called AcrB, expels toxins from the cytoplasm through the cell membrane to
the outside. Like ATP synthase, it has three active sites at one end where the binding
occurs, and it operates on proton motive force; but unlike the former, it performs functional rotation instead of
Murukami et al., a team of five in Japan,
described the machine in the 14 Sept issue of Nature.1
Here is a simplified picture of how it works. Picture a pie with three slices and follow a toxin
from the inside of the cell, through the AcrB disposer, to the outside. One of the slices has
a port open and ready for use; we follow the molecule inside as it gets dragged in because of the
proton flow. A trap
door lets us into the first chamber then snaps shut. Inside, we are squeezed into another chamber, then into
a tunnel, then handed off to a membrane protein that ejects us out to the exterior environment.
The squeezing occurred because the
neighboring pie slice opened its port when ours closed. When the third slice opened in turn,
we were ejected into the tunnel. In this functional rotation model of the action,
each of the three segments cycles through three states, and affects the state of the neighboring
segment. The result is a continuous garbage-disposer like operation that sucks in the toxins,
binds them, and ejects them out. Apparently each segment can handle a wide variety of substrates,
and adjacent segments might be working on different molecules simultaneously.
Theres one bad side effect of this technology for us humans. For doctors
trying to administer chemotherapeutic drugs or antibacterial agents, the bacteria put up a challenge;
they can be ejecting the drugs as fast as the doctor administers them. This is one way bacteria
gain immunity to drugs. Finding ways to disable these ubiquitous membrane proteins
may be easier now that we know how they work. This particular machine operates in the lab
bacterium E. coli, but there are other types of these multi-drug transporters (MDTs)
in other organisms that work in other ways. In the same issue of Nature,2
two Swiss researchers described a different MDT in S. aureus called Sav1866. Instead of
proton motive force, this member of the ABC family of MDTs uses ATP to twist the toxin out of the membrane.
In the case of the rotary machine AcrB, both the research team and commentator
Shimon Schuldiner (Hebrew U) couldnt help but notice the resemblance to ATP synthase.
AcrB lacks the mechanical rotation of the gamma subunit, and seems to lack the rotating carousel driven
by protons, but it does have three active sites that appear to operate in turn like a rotary engine.
Schuldiner did not explain any details of a relationship, but speculated that AcrB might be a missing
link of sorts: It is possible that this is a remnant of the evolutionary process that led to
the development of true rotary molecular machines. Other than that, and an
offhand remark earlier in the commentary that MDTs have evolved into many different forms
to act on a wide range of xenobiotics [i.e., alien molecules], the only other reference to evolution
in any of these three papers was a speculation about Sav1866 by Dawson and Locher. Noting the
functional similarity but distinctly different architecture between Sav1866 and another member of the
ABC family of MDTs, the bacterial lipid flippase MsbA in Salmonella, they cannot
see an evolutionary relationship between them: The observed architectures of MsbA and Sav1866
remain incompatible, even when considering that the proteins may have been trapped in distinct states,
they note. So what is the answer? How did these structurally different yet functionally similar machines
originate? They leave it at, the differencesif realwould indicate a convergent evolution
of the two proteins.

biochemists are finding, so that the Darwinists know what they are up against. The cheap calls of
convergent evolution and remnants of the evolutionary process and other
such calls to accept evolution as an assumption are ringing hollow, and need to be ejected with the

Plant Protection: A Modern Medieval Castle Story
Next headline on:
Vigilant guards stand at the gates. In times of peace, they let down the drawbridge,
and the townspeople carry on their trade. Farmers bring in their crops for the marketplace,
and local craftsmen and pedlars keep the local economy bustling. Yet the sentries maintain
a watchful eye, aware that numerous interlopers are about. Aliens constantly seek entry into
these most vulnerable points in the castle walls. The guards, however, are well trained.
They know the behavior patterns of most would-be intruders. Any attempted invasion is usually
rebuffed by a rapid drawbridge up! response till the danger has passed. Day and
night, through all seasons and all kinds of weather, these diligent sentries stand ready at their posts,
maintaining security for the townspeople inside.
One day, after the gates had been closed after a day of feasting and celebration,
a clever interloper showed up. He looked a
little strange, but dressed as a local merchant, he insisted he had important business in town
that couldnt wait till morning. The guards, a bit wary at first but in high spirits
from the long party, checked his I.D. He had the necessary documents, and knew the password.
Yet this interloper,
armed and dangerous, carried a secret weapon: a chemical spray able to intoxicate the guards and make
them susceptible to the power of suggestion. Let me in, the interloper whispered
softly after surprising the guards with his potent perfume. Its all right.
Everything will be just fine. No one will ever know. He imitated the motions of
turning the cranks that would relax the heavy chains. Overcome by the hypnotic
vapors, the guards followed his motions, and soon the drawbridge came winding down.
Once inside, the interloper went quickly to work. A local constable was quickly
put out of commission by turning his gun against him. The intruder entered a house, subdued the occupants, and set up a
base of operations. He signaled his cohorts, and before long, before the townspeople even
knew what happened, the defenses in which they had trusted had been compromised: an enemy force
was inside the gates.
A medieval tale? No; look at your house plant. It could be happening
right there. Yellow or sickly leaves could have suffered a similar fate. Scientists
have just discovered that bacteria can trick a leafs guard cells into letting down their
Botanists have known about guard cells for a long time. Leaf surfaces are
pockmarked by openings (sing. stoma, plural stomata), each surrounded by a pair of
guard cells that regulate the opening and closing of the stomata. The openings are important
for exchange of gases and for transpiration, the release of water vapor from cellular respiration
to the atmosphere. Like water balloons under pressure,
the sausage-shaped cells become rigid as water is pumped in, creating turgor pressure.
Unable to increase their girth, the guard cells curve outward, opening a pore between them.
Relaxation of the turgor closes the stoma. There can be a thousand stomata per square
millimeter on a leaf surface (see CSBSJU
lecture notes), each with their own pair of guard cells.
The opening and closing of stomata is not
merely a function of water availability. A host of specialized proteins and molecules
regulate the guard cells actions. The complexity of these regulators was described this month by
a trio of researchers at Penn State. Reporting in PLoS Biology,1
they identified more than 40 components of the guard cell regulatory network, and that the network
is robust against a wide variety of perturbations. From conifers to cacti, from African violets
to garden weeds, stomata with their guard cells keep trillions of leaves operating as effective harvesters of
sunlight, with benefits for all life. To our knowledge, the researchers said without mentioning evolution,
this is one of the most complex biological networks ever modeled in a dynamical fashion.
But back to our castle story. Other scientists just made a surprising discovery.
Stomata are not only avenues for gas and water exchange: they really have guard cells with
a security role. Melotto et al. at Michigan State, writing in Cell,2
found that guard cells respond to the presence of bacteria. They can sense the flagellin molecules
in Pseudomonas syringae, a common leaf pathogen, and close the stomata to defend against invasion.
This clever bacterium, though, like our castle intruder, carries a molecule that mimics the open
sesame command of regulators inside, and can trick the guard cells into letting down the leaf
defenses. Once inside, the bacteria have a much easier time going about their work of using
leaf resources for their own needs. Some infected cells will try to stop the invasion by committing
suicide, but the inner defense system is not nearly as effective as the stomata. We
can no longer think of stomata as simple, passive ports of entry for bacteria.
Surprisingly, they wrote, we found that stomatal closure is part of a plant innate
immune response to restrict bacterial invasion. In the same
issue of Cell,3 Schultz-Lefert and Robatzek commented on this discovery,
adding that pathogenic bacteria have evolved strategies to suppress the closure of stomata.

We tricked you by posing this as a contest between good
and evil, between peace-loving leaf cells and dastardly bacteria up to no good. Metaphors bewitch
you, remember? (see 07/04/2003). Plants and
bacteria are not sentient beings. We should liberate our minds from the tendency to
view these ecological interactions in anthropomorphic terms. The converse is not true;
human beings are sentient moral agents; no one should take this commentary as support
for viewing terrorism as a natural regulatory response to civilization, for instance.
But it is possible that bacteria act as a counterbalance in the overall ecology.
Nature is filled with counterbalances, with accelerator pedals and brakes, with promoters
and terminators. Bacteria invading a leaf may look to us like selfish invaders,
but what if they have a role to play, preventing a plant community from growing
beyond its resources? Many bacterial invasions occur after periods of high humidity
or drenching rainstorms. Its possible to look at the ecological community as a
well-regulated system of checks and balances, responding to perturbations in a way that
ensures the long-term survival of the whole. Most of the time, it works. Plant
communities endure despite major geological and climatic changes. Clearly, things get out of balance
sometimes, but maybe that was not the original intent of these well-regulated systems in the original creation.
We dont need to resort to the evolutionary selfishness metaphors. We should not

Do Mammals Depend on Virus Help? 09/12/2006
The important point of these articles is not in some moral anthropomorphism, but in the realization
that here is another example of an interrelated, regulated system that could never have evolved
by some unguided processes. Stomata may have looked like simple pores to earlier scientists;
now we know that there is a whole network of regulators and detectors, composed of at least 40 parts,
that work together to ensure the proper functioning and security of the photosynthetic factories on
which all multicellular life depends. This has been the pattern of scientific discovery ever
since the discovery of DNA. No matter where you look, life is much more sophisticated than
one could have imagined.
An evolutionary astrobiologist
was heard today commenting on the arrangement of cells in leaves. He pointed out that not only
are individual leaf cells optimized to filter in the solar wavelengths most useful for photosynthesis, but that
they are stacked in formations that act as waveguides, funneling in the vital green wavelengths while
reflecting and passing through the infrared wavelengths that would otherwise overheat the power
generators. In other words, here are two separate and independent designs that contribute to
the optimization of photosynthesis. In a declaration of folly astonishing in its dimensions,
he exclaimed, without even batting an eye, isnt it amazing that plants figured this out by themselves!.

Researchers found that sheep depend on a retrovirus to become pregnant.
Retroviruses (those that can insert themselves into a genome of a host cell) include the dreaded
HIV and generally have a bad reputation. Remnant retroviruses are prevalent in many
animal species and have been considered a class of junk DNA, having mutated
away their ability to cause infection.
Science Daily, however,
reported on research that shows that naturally occurring endogenous retroviruses
are required for pregnancy in sheep. A certain class of retrovirus, enJSRV, is critical for
formation of the placenta without it, embryos cannot implant and are miscarried.
Other retroviruses, rather than causing disease, may be essential for protection from
infection, the article said.
How could such cooperation between virus and host evolve? An
evolutionary explanation was included in the article:
Further, Palmarini said, The enJSRVs arose from
ancient infections of small ruminants during their evolution, said Dr. Massimo Palmarini,
a virologist at The University of Glasgow Veterinary School. This infection was beneficial
to the host and was then positively selected for during evolution.
In other words, animals with enJSRVs were better equipped than those without.
Therefore, enJSRVs became a permanent part of the sheep genome and, in these days,
sheep cant do without them.
Yet this seems merely a post-hoc speculation rather than a
testable hypothesis. Perhaps there is more cooperation going on between mammals and
their tag-alongs than previously realized.
Palmarini ought to read what Jerry Coyne wrote about
evolutionary theory (08/30/2006). Evolution neither
predicted nor expected this surprising discovery. The explanation resembles the
habit of Kruschev-era communists to spin every political and economic observation,
no matter how contradictory, into terms of class conflict and dialectical materialism.

On the day of the attack itself, there was not much that could be said here,
other than to reprint words of great patriotic hymns (following
09/12/2001 entry). Today, 09/11/2006, the 5th anniversary
of the attacks, President George W. Bush ended his address to the nation with a reference to the Creator:
If you think back to the commercials of the Leave-it-to-Beaver era,
all germs were considered evil. Wondrous kitchen products like Lysol helped the
modern homemaker destroy the wretched bugs and keep the kitchen shining
spic-and-span and germ-free. It is becoming apparent now, by contrast,
that most bacteria are beneficial to humans (see 08/02/2006
entry), and that the world is teeming with more viruses than previously conceived, most of which are harmless.
This does not mean we should give up cleanliness and hygiene, but it means that we need to
rethink our view of natural evil.
A new view seems to be emerging that life not only tolerates, but may ultimately
depend on, bacteria and viruses.
The relatively small number that cause disease and harm, like brats in the playground,
steal most of our attention. What if the bratty germs are really beneficial
players gone awry? That would fit a Biblical creation model. A design-based
research program could investigate the beneficial interactions of animals with their
micropartners and retroviruses, instead of giving up and spraying the junk

Patients in Vegetative State May Be Aware
Remember the arguments put forth for why Terry Schiavo should be allowed to die?
They revolved around the awareness of those said to be in a persistent vegetative state.
Now, researchers reported in Science1 that a patient diagnosed in a
vegetative state was aware of what was going on:
We used functional magnetic resonance imaging to demonstrate preserved conscious awareness
in a patient fulfilling the criteria for a diagnosis of vegetative state.
When asked to imagine playing tennis or moving around her home, the patient activated
predicted cortical areas in a manner indistinguishable from that of healthy volunteers.
The researchers called the condition of vegetative state one of the least understood and
most ethically troublesome conditions in modern medicine. The ran tests with functional
MRI on a 23-year-old woman who had suffered severe injury in a car accident. Unresponsive
but with preserved sleep-wake cycles, she was diagnosed as in a vegetative state by international
These results confirm that, despite fulfilling the clinical criteria for a diagnosis
of vegetative state, this patient retained the ability to understand spoken commands
and to respond to them through her brain activity, rather than through speech or movement.
Moreover, her decision to cooperate with the authors by imagining particular tasks when asked
to do so represents a clear act of intention, which confirmed beyond any doubt that she
was consciously aware of herself and her surroundings.. Of course, negative findings in
such patients cannot be used as evidence for lack of awareness, because false negative
findings in functional neuroimaging studies are common, even in healthy volunteers.
However, in the case described here, the presence of reproducible and robust task-dependent responses
to command without the need for any practice or training suggests a method by which some
noncommunicative patients, including those diagnosed as vegetative, minimally conscious, or
locked in, may be able to use their residual cognitive capabilities to communicate their
thoughts to those around them by modulating their own neural activity.
Another case was reported by the BBC
News. A victim of an acute viral infection was diagnosed in a vegetative state.
She could not move her facial muscles to indicate reactions, but was aware of what was
being said around her, and felt scared. I felt trapped inside my body,
she later reported. The only clue to her hopeful parents came from a brain scan that
showed she was processing information presented to her.
Update 09/13/2006: Nature (443, 14 September 2006)
published a news item (pp 132-133) and editorial (pp 121-122) on this
finding, but claimed the patient in this case seems to have been much less severely injured
than the permanently vegetative Terri Schiavo, whose case inflamed the moral debate over whether
those who show no signs of recovery should be allowed to die. Surprisingly, even
though the news item admits that there is a continuum of states, that some on the continuum may
be progressing toward eventual recovery, and that the binary diagnosis
of vegetative state can no longer be taken for granted, the editorial claims,
This case has little bearing on ethical questions over whether or not the most severe cases
should be denied treatment and allowed to die, because in the most severe cases the chances
of finding any sign of awareness is negligible. Yet the parents and friends of Terry Schiavo
constantly argued that she was aware enough to follow objects and display emotions. Since
she was killed in March 2005, we will never know if she could have passed a similar fMRI scan test.
1Owen et al., Detecting Awareness in the Vegetative State,
8 September 2006: Vol. 313. no. 5792, p. 1402, DOI: 10.1126/science.1130197.
Recall the anger and outrage against the people who protested the death of Terry Schiavo.
Remember the claims that they were the ones being unreasonable and insensitive, and
that the compassionate thing to do was to let Terry die, because she was not really living.
Now picture the possibility of her hearing all these things said about her but trapped inside,
unable to communicate. Imagine the fear and helplessness and pain of knowing you were
being intentionally allowed to starve and dehydrate to death. How many other times has a similar
decision been made to a patient assumed to be vegetative and unaware? Remember,
these scientists said that negative responses in the brain scans are not definitive in diagnosing
the awareness of a person.

After Nature printed an upbeat press release last month that stem cells could be extracted
without killing an embryo (see 08/25/2006),

out none of the stem cell lines survived, and that more than one cell had been extracted
from the embryos, contrary to claims made in the press.
Associated Press reported (see Fox News)
that Advanced Cell Technology was accused before a Senate hearing of misrepresenting its

Darwins Tree of Life fruit stand found an upbeat salesman in John Roach at
Geographic this week. In his update on the Assembling the Tree of Life

New cures, supercrops, and secrets of evolution may
emerge from the fast-growing branches of the Tree of Life,
As more animal genomes get sequenced, the task of organizing them into
ancestral trees becomes more complex. There is more hope than accomplishment at
this stage: In trying to figure out how species are related to one another, it
immediately becomes clear this is a very large problem that doesnt have
an end in sight any time very soon, said one researcher. The enormous
task of determining who is related to whom is not a trivial undertaking, nowhere near
This means the fruit is not yet ripe for the picking, either.
Researchers hope that predictions can be made once the structure of the tree takes
root in scientific consensus.
For example, [James] Collins [NSF] says, if scientists want to find an organism that
has properties useful in the cleanup of oil spills, they would first turn to microbes
that have known beneficial properties and then examine the microbes nearest
relatives for good matches.
Yet these promises beg the question whether they depend on the Tree of Life project for fulfillment.
Scientists were making headway on these questions long before the AToL program started.
To help engineer new crops, agricultural researchers might study genetic
traits that make crops drought resistant.
[Michael] Donoghue, the Yale biologist, says scientists can use the tree
to understand where emerging infectious diseases originate and to search for organisms
that have evolved resistance to the diseases in question. Such clues can lead to
the development of new drugs, he says.
Applications are everywhere, he said.
The article also
begs another question: whether Darwins tree is the only paradigm fitting the data
and providing the benefits. Artificial selection has a long history preceding
Darwin himself, let alone his tree analogy or this new AToL project. Also, since
creationists acknowledge a nested hierarchy picture of classification without the
necessity for common ancestry, why wouldnt that structure provide the same
heuristic for scientific research, and the same benefits, without the Darwinian baggage?
Dont count your fruit before it ripens. Darwins tree has already dropped so many

Welcome to an imaginary world of Red Queens, Green Beards and warring armies: the world of
evolutionary theory. Though its adherents work in prestigious universities and
laboratories in the real world, they seem preoccupied with speculative visions of
imaginative fitness landscapes
even when defending evolutionary theory as the best explanation for natural phenomena,
and essential for our understanding and progress in science. This can be seen in
two recent papers, one pro-evolution and one critical of it, that center on the question:
is evolutionary theory essential to biology?
Ajit Varki defended evolution all the way down in a paper in Cell1
with the self-explanatory title, Nothing in Glycobiology Makes
Sense, except in the Light of Evolution. Adapting the title from a famous quote by
Theodosius Dobzhansky, used more often as a club than a flashlight at school board hearings,
Varki attempted to show the utility of evolutionary theory to one specialty:
glycobiology, the study of biological sugars. This is a complex field of unity
and diversity, complexity and simplicity, conservation and diversification.
Cells use sugars inside and outside for a variety of functions, but pathogens also attach
to them. Glycobiology seems a confusing picture, from highly-conserved enzymes that have
changed little from mouse to human, to variations within species and even within the lifetime of
In his defense of evolution to make sense of it all, he invokes the Red
Queen effect (running in place to get nowhere: see 05/16/2004,
03/31/2006), co-evolution and evolutionary arms races.
Its not clear, however, whether his presentation would convince a critic. For one
thing, most of his examples deal with microevolution, which is not controversial, even among
the most ardent creationists. The only exception is his treatment of possible means of
speciation, one species splitting into two which also fits within most creationist
frameworks. Nowhere in his article, however, does he explain how glycobiology needs evolution
to explain the major changes most often implied by the term evolution.
A critic might also point out that Varkis ideas are amply sweetened with
speculation, by his own admission: Whatever the reader might
think of the speculations in this Essay, he states in conclusion, it is safe to
suggest that approaches to understanding glycan biology must fully take into account the
role of multiple and often simultaneous evolutionary processes, an aspect that has received
limited attention. That seems an admission that many biologists have up till now
not given it much attention a contradiction to Dobzhanskys claim.
Its noteworthy how many times Varkis scenarios are salted with qualifiers and
peppered with hopes:
Overall, one can speculate that some episodes of speciation might be
mediated by pathogens that bind to specific forms of cell-surface glycans.
A lethal pathogen that binds to glycans of a certain species to initiate infection might
markedly reduce the primary population, leaving geographically isolated subpopulations that have
the opportunity to evolve into new species.
Some of the survivors are likely to have been selected because of random
glycan variations that allowed them to escape from infection with the pathogen.
Such survivors may have secondary alterations in glycan biology that are permissive
for pleiotropic changes in embryogenesis and/or morphogenesis.
Glycan changes also might alter fertilization barriers, causing either reproductive
isolation or anomalous fertilization by closely related species.
Any or all of these mechanisms could support the formation of new species.
Many of these speculative ideas are testable by observational studies and possibly by
long-term experiments. [No examples cited.]
Thus, glycans may be trapped in neverending cycles of
evolutionary Red Queen effects in which long-lived hosts must evade the
more rapidly evolving pathogens that infect them by changing their glycan expression patterns,
without compromising their own survival (Van Valen, 1974 and Hamilton et al., 1990).
The colorful term, Red Queen effect, recalls the comment to Alice by the Red Queen
in Lewis Carrolls Through the Looking Glass that it takes all the running
you can do, to keep in the same place. This may explain the remarkable
structural variations of glycans in nature, which contribute to biological diversity and perhaps
even to speciation.
Thus, the glycans of complex multicellular organisms with long life cycles may be
subject to evolutionary Red Queen effects....
For example, cell-type-specific expression of certain glycans can mediate specific
biological roles within an organism (Lowe and Marth, 2003), which thus may be under positive selection.
Additional Red Queen effects may arise from the fact that many pathogens use a
successful form of molecular mimicry,...
Such diversification and redundancy may be driven by sexual selection and sexual conflict....
The question that needs to be asked is not whether evolutionary theory may explain the
phenomenon in question, but whether it is essential for any sensible
explanation: whether or not nothing makes sense except in the light of evolution.
A Biblical creationist, for instance, might be perfectly content with certain aspects of these
mechanisms at the microevolutionary level evolutionary arms races and Red Queen effects
in a world cursed by sin and infected with pathogens. He might claim that the Creator provided
enough versatility for organisms to be able to adapt to changing environments, so that an animal
would not be wiped out by the first encounter. Yet the same creationist would still vehemently deny
molecules-to-man evolution, the kind envisioned by Darwin and Dobzhansky.
Another assertion left unproved is whether biology really needs the kind of speculation
Varki illustrated in its day-to-day business. This question was taken up by a well-known critic of evolution,
Jerry Bergman, who investigated whether practicing biologists actually illustrate Dobzhanskys claim
in their work. In a recent article on TrueOrigin,
Bergman concluded that Dobzhanskys claim is a myth. He interviewed scientists and researched textbooks,
and found that evolutionary theory was rarely mentioned or used, and when it was, it was more an afterthought than
a substantive part of the discussion:
If, as Dobzhansky stated, nothing in biology makes sense except in the light of evolution...,
why is it rarely, if ever, mentioned in most natural science books? We usually use the leading
college texts in each area (for example, the A&P text we use is the 10th edition of Hole, a standard text).
And why is it a minor topic even in most introductory biology books that cover the subject in more
depth than most all other courses except formal classes on evolution?
He concluded, This statement is ideologically not factual.
Biology makes perfect sense without ever mentioning Darwinism.

Flagellar Swimmers Attain Mechanical Nirvana 09/06/2006
Next headline on:
Those little germs that scientists love, E. coli you know, the ones with
the flagella that intelligent-design folk get all excited about well, they move through
the water pretty efficiently with those high-tech outboard motors of theirs. Some Pennsylvania physicists
reporting in PNAS1 measured the swimming efficiency of bacterium Escherichia coli
and concluded, The propulsive efficiency, defined as the ratio of the propulsive power
output to the rotary power input provided by the motors, is found to be ~ 2%, which is consistent
with the efficiency predicted theoretically for a rigid helical coil.
An engineer cant get much more efficient than that, in other words, even in theory.
Later in the paper, they summarized, The measured [epsilon: i.e., propulsive efficiency]
is close to the maximum efficiency for the given
size of the cell body and the shape of the flagellar bundle.
That efficiency rating is the overall measurement for the package. Many
bacteria have multiple flagella, however, and ascertaining the individual contributions of
each component, and the subtle hydrodynamic interactions between them,
is a difficult task. They did, however, assess the length of the flagellum as a factor
in the optimal performance, and concluded that flagella are
as long as required to maximize its propulsive efficiency.2
They measured the swimming efficiency by capturing single bacteria in optical
tweezers and putting them into a measured rate of flow. The work was edited by
Howard Berg of Harvard, a pioneer of flagellum research (see his 1999 article on

Fast-forward to 18:20. How does it know when to stop growing? There must be feedback from
the growing tip to the control mechanism in the cell body.
Man-made outboard motors are stubby-shaped, loud,
polluting, inefficient monstrosities that generate huge wakes. Since the
bacteria have already mastered propulsive efficiency, maybe this will inspire some
boat builder to do a little biomimetics. We should see if flagellar construction scales up
to human proportions and maintains the efficiency rating. If so, lakefront property owners
would love them for it.

My, how history repeats itself often in unexpected ways.
In ancient times, our ancestors got the heavy work done by hitching oxen, horses
or slaves (like Samson, see pictures 1
to a harness and making them turn a grinding wheel. The same principle is now on the cutting
edge of modern applied biological engineering only now, the movement is measured in micrometers, and the
beasts of burden are bacteria. Scientists in Japan, publishing in PNAS,1
have successfully hitched their harnesses to multi-legged crawlers named Mycoplasma mobile
and made them turn a gear 20 micrometers wide, many times their size.
In the contraption rigged by Hiratsuka et al., the bacteria walk inside a
circular track, pushing a six-petal rotor made of silicon dioxide above them. The inventors
(slavedrivers?) developed a surface that would ensure the majority of the cell microtransporters
would move in one direction with the right amount of friction. The cooperative workers achieved forces of
2 to 5 x 10-16 newton-meters, with
rotation rates of 1.5 to 2.6 rpm. To the best of our knowledge, they boasted with some merit,
a micromechanical device that integrates inorganic materials with living bacteria has not
succeeded until this study. (They did, however, reference the PNAS research reported in our
Saddle Up Your Algae.)
The inventors didnt mention evolution once in their paper. Instead, they spoke
in glowing terms about their little microscopic oxen and marveled at their technology.
First, they scanned the arena of biological micro-machinery with the delight of a gadget freak:
Nature provides numerous examples of nanometer-scale molecular
machines. In particular, motor proteins, which efficiently
convert chemical energy into mechanical work, are
fascinating examples of functional nanodevices derived from
living systems. The molecular mechanism underlying the
function of these motors has long been a major focus of
biophysical research, and the information emerging from those
studies should greatly aid in the design and fabrication of novel
How about the machines employed by their chosen beast of burden? The praise service continues:
Turning an eye to higher-order biological structures reveals
many examples of excellent mechanical devices, including bacterial
and eukaryotic flagella and muscle sarcomeres. These
motile units are tens of nanometers to several micrometers in
size and consist of multiprotein complexes built up with atomic
accuracy through the self-assembly and self-organization of
protein molecules within cells. In general, these devices work far
more efficiently and intelligently than the isolated proteins but,
because the principles and mechanisms of self-assembly are only
vaguely understood, we are currently unable to assemble higher order
motile units from the isolated component proteins outside
the cells. Consequently, research aimed at developing hybrid
devices using biological motile units is rare at present.
Mycoplasma mobile, a species of gliding bacteria, is another
example of a higher-order unit (cells in this case) with superb
motility. M. mobile has a pear-shaped cell body ~ 1 micrometer in
length and moves continuously over solid surfaces at speeds up
to 2-5 micrometers per second. The mechanism by which it glides remains
unknown, although a mechanical walking model that makes use
of the rod-like structures protruding from the cell surface has
been proposed. Although three proteins have been
identified as essential for gliding, we speculate that this motile
system may need a dozen additional proteins, including various
So why reinvent the wheel? Why go to all the trouble to invent walking nanorobots, when
bacteria have it all figured out? The inventors list other reasons for enlisting biological
beasts of burden instead of trying to start from scratch:
As a result, it is currently impractical, if not
impossible, to reconstitute fully functional motile units from the
isolated proteins of M. mobile in vitro. For that reason, we have
been attempting to construct micromechanical devices using
intact M. mobile cells instead of the isolated proteins. A key
benefit of this approach is that hybrid devices into which living
cells are integrated enable us to take advantage of preassembled
excellent motor units that have the potential for self-repair or
self-reproduction when damaged.
So there you go: spare parts and repairs come included with the package.
Oxen must be fed, however, and they didnt talk about that (cf.
Someone else may have to invent the nanomanger.

This is nothing less than intelligent-design research in action: intelligent humans

overlap between artificial and biological design is almost seamless. What dividing line
could separate the two domains? Who could claim that mans part represents intelligent
design, but the biological part is the result of a long series of mistakes? The researchers
even spoke of manipulating the bacteria through genetic engineering to conform the
protein moving parts to their
design goals. That will blur the distinction even further.

If Martians found

unguided process of self-organization? The engineers at JPL would justly be
offended. The future belongs to those who think intelligently, and know design

small pieces of DNA will probably always be impossible, [Paabo] says, and from
what we know about the chemical stability of DNA, sequence retrieval will always
be on this side of a million years ago, so dinosaur DNA is beyond our
reach. The problem, he says, is that DNA is extremely hydrophilic, and exposure
to water molecules as well as atmospheric oxygen and background
radiation breaks it down. Even under highly favorable preservation conditions,
such as mummies in a dry and cold desert, DNA disappears from a specimen
within a few hundred thousand years. However, even given such limitations,
many interesting discoveries still lie in ancient DNA.

The bacterial flagellar motor excites considerable interest because of the ordered
expression of its genes, its regulated self-assembly, the complex interactions of its many
proteins, and its startling mechanical abilities, begins a paper in Nature
by three Caltech scientists.1 They performed electron cryotomography
imaging on the flagella of Triponema primita, a different critter with a different
model from the flagellum found
in E. coli, the favorite toy of microbiologists (with an outboard motor that is an icon of the
intelligent design movement). Treponema is a little spirochete that lives in the hindgut of
termites. It has two flagella, one at each end, that apparently rotate on its
inside and make the organism gyrate rather than swim through liquid.
The Caltech team
got good images of the stator for the first time. Their exterior and cross-section
illustrations show a multi-part
circular structure with 16-fold symmetry and complex contours, with rings and other parts of unknown function.
This particular motor apparently operates in low gear. It is larger than the
E. coli or Salmonella
flagella and apparently runs at much higher torque.
These differences have important implications for current models of the functional and
architectural relationships of the components. Whereas the Salmonella
motor spins just the flagellum, because Treponema flagella are periplasmic, it is thought
that they cause the whole cell to gyrate. Thus, each rotation may be much slower
and require greater torque. The unusually large stud ring, C ring and rotor in
Treponema may serve to increase torque by increasing the length of the effective
lever arm through which each stator stud acts. These larger rings
may also accommodate more stator studs and FliG molecules around the ring, in effect
gearing down the Treponema motor so that the passage of
each proton across the membrane produces a smaller angular rotation.
The paper includes a link to
an animation video that shows the motor in operation from different angles.
The authors talk a lot about machine specs, but dont mention anything about evolution.

Theres a little Neanderthal in a lot of us, claims
Telegraph. This is bad news and good news:
People who have large noses, a stocky build and a beetle brow may indeed be a little
Neanderthal, according to a genetic study. But the good news is that other
research concludes that Neanderthals were much more like us than previously thought.
The claim is based on comparisons of linkage disequilibrium statistics in the genomes
of humans from different continents, which cannot be explained by human ancestry without
interbreeding from an archaic population. The authors of a study in
PLoS Genetics1 inferred a Neanderthal origin for the archaic lineage
since West African genes do not appear likely candidates. Another prop in the
Telegraphs good-news-bad-news joke is the finding that
Neanderthals may have been more human-like than previously assumed. The authors
of both studies failed to state whether the concentration of Neanderthal characteristics
reached a peak in the genes of female Olympic athletes in East Germany.
Lost somewhere in the excitement of having an explanation for our tendency
to grunt, scratch, and club each other were the upsets implicit in these findings.
Having Neanderthal genes argues against the popular out of Africa origins.
They also dispute the assumed genetic isolation of Neanderthals and modern humans.

Evolution Back on Federal Funding List
The potential for variability within the modern human population is
probably far greater than realized. The Old Testament talks about races of
giant humans (the Rephaim and others) in isolated populations. Racial and
physical differences could quickly arise between populations segregated by language and then by locale
after Babel, for instance. If the hobbits of Indonesia become accepted
as kinfolk, theres tremendous physical variety between them and Goliath.
Even today, the range in human traits is quite remarkable, yet we are all interfertile,
intelligent, communicative, and fully aware of a sense of right and wrong.
None of genetic variability past or present implies that people have ever been anything less than fully
human, with language and moral responsibility. What anthropologists call Neanderthal could well
have been a group of capable, smart, strong human beings, accustomed to life in harsh climates.
Perhaps they shunned cities and tended to remain strongly tribal, but left some genetic
overlap with the rest of us. The brutishness in the human lineage is not due to
ape in our ancestry, but rather to sin (see
as has been evident in all tribes, kingdoms, nations and peoples around the globe,
regardless of average height, skin color, face shape and cultural preferences.

Boy, that was a close call. Evolution research almost got dropped from federal
funding. Turns out it was an accidental oversight.
Daily reported that the oversight sparked heated protests from academics and
evolution supporters who expressed fears that the omission might have
been part of an attack on Darwinian evolution by religious groups.
The U.S. Department of Education quickly acted to reinstate evolutionary
biology to the list eligible for federal grants for undergraduate research.
Evolutionists welcomed the quick response: If (the omission) was deliberate, it is
certainly the case that when it came to light, wiser heads prevailed, said Becky
Timmons of the American Council on Education. Laurence Krauss of Case Western Reserve
University used the occasion to point out the danger: There are well-funded efforts
in this country that have been inappropriately attempting to attack the teaching of
evolutionary biology on what appear to be religious grounds.
Need we point out to Dr. Krauss that the funding for
these attacks (note the fear-mongering in
the militaristic terminology) is from private sources? And that these attacks
are only concerned with allowing fair and honest investigation of the truth claims of Darwinism,

They are right to be alarmed. A great many people have come to regard Darwinism as tedious,
illiterate, uninformed and tendentious. Darwins theories seem destined to disappear
by negative selection, an interesting but rare example of a Darwinian process reaching a sound conclusion.

Darwinism and Evolution
- Beginning of article -
For teachers, students and laymen unwilling to wade through all the many paragraphs of technical text
(especially text lacking certainty about what happened during evolution), this issue of Science provided
neat, colorful diagrams called The Evolution of Function & Form for easy downloading and
classroom use. The charts provide
the basic story lines, illustrated and simplified for easy digestion, without all those troubling details.
The caption explains cheerfully, A special two-page feature available as individually
downloadable images (suitable for slides) or in PDF form explores the insights on
the evolution of organs such as the brain, eye, and heart, and on pattern formation in general,
that are emerging from modern genetics and genomics.
- Brain: Elisabeth Pennisi tackled the biggest problem first: the evolution of
the human brain, in Mining the Molecules that Made Our Mind.2
Surprisingly, she began by criticizing news reporters who got carried away with the announcement Aug. 17
(08/22/2006) that a particular gene named HAR1F,
possibly related to the cerebral cortex, contained many more differences between apes and humans than most other genes.
Headlines like A single gene led to humans and Revealed: the gene that gave us bigger brains
she considered way overblown. HAR1F is only one of several candidate genes evolutionists
have speculated might have been involved in brain evolution. Pennisi pointed out the bandwagon
effect of working on stories of human origins, and warned that caution is in order:
Many scientists find the potential to understand ourselves irresistible. A rush
of comparative genomics results about human evolution are being presented at meetings, and
publications are starting to stream out. Everyone is jumping on the
bandwagon, says Bruce Lahn, a human geneticist at
the University of Chicago, Illinois. Progress at identifying the DNA tweaks that
distinguish people from other species should be swift. Within a year or two, we
will have a comprehensive list of genome changes to start looking at, says Christopher A.
Walsh, a neuroscientist at Harvard Medical School in Boston.
Pennisi next emphasized the differences between the human brain and the chimp brain. She
offered only hints of genes that might have undergone positive selection in the alleged pathway
from a common ancestor, HAR1F being the latest headlined candidate.
Emphasize start. Despite what the headlines imply,
genomic data so far offer provocative clues rather than direct answers to what caused humans to
branch out from the primate tree to become walking, talking, creative beings.
Tying genomic events such as a gene duplication
to human evolution is a challenge, because often researchers know little about
what their candidate genes do. To make a concrete connection between a genetic change
and the evolution of the human brain is a much slower process, says Walsh.
are finding that the differences may not be so much in the genes and proteins themselves, but in
their rates of expression. That leads to a new plot line: These extra copies are
material with which evolution can play, perhaps dedicating the activity of one copy of
a gene to a subset of cells, for example, leading to evolutionary innovation.
Nowhere, however, was an explicit example of innovation by duplication provided. Only the
suggestion was proffered: e.g., a particular gene with more copies in humans than mice
may have evolved crucial new functions in the process. In another example
of a gene where humans have a different number than apes, No one knows exactly what the gene does,
so it is certainly premature to expect anyone could understand how it could help produce a human brain.
Even noting that the gene is active in the brain is not conclusive, she said. The work highlights the
potential importance of duplications in the emergence of novel genes within
the hominoid lineage said one researcher thus assuming evolution rather than demonstrating it.
The same flaw exists in plot lines that parts of an ape gene were replaced on the path to humans.
Wishful thinking and imagination become substitutes for scientific demonstration. Notice:
However, at some point in hominid evolution, part of SIGLEC-16 must have
replaced the front part of the DNA of SIGLEC-11, creating a brand-new, human specific
protein, says [Ajit] Varki [UC San Diego]. The gene for this protein now turns on in the
human brain, specifically in microglia, cells known to be important to the growth of nerve cells
(Science, 9 September 2005, p. 1693). The finding is tantalizing, but of uncertain
significance, Varki points out.
A question could be asked whether a tantalizing observation might just as well be
applied to an alternative view, or whether tantalizing findings of uncertain significance
deserve publication in a scientific journal. At this point, shockingly, Pennisi seemed to pull
several rugs out from under all such claims and headline-grabbing genes
For these and other reasons, Pennisi said the glorious headlines about brain evolution being found in the genes
should be doused heavily with the salt of realism.
Pääbo shares Eichlers frustration at the field being unable to move more swiftly
beyond highlighting candidate brain-evolution genes. Its getting a little
stale, he admits, to say, I have another case of positive selection.
The challenge is to link the evidence of positive selection to brain function.
- theres a tendency for people to think this [gene] is it--the explanation for why people are unique....
- For his part, Varki warns that the quest to understand human evolution is too brain-centric.
We are also defined by differences in our reproductive, musculoskeletal, and immune systems, as well as by our skin, he points out.
- Moreover, almost every gene linked to human brain evolution comes with questions about the
strategies used to establish the connection. For example, some scientists are not convinced
that the methods used to detect positive selection in a gene are reliable or that the
results will hold up as more genome sequences are added to these analyses. Genes
that appear to change rapidly may still fall within the range of normal variation, for
example. Moreover, rapid change in a gene or extra copies does not mean that these genes
are [all] important during the evolution of the human brain, says [Xun] Gu [Iowa State].
- Some scientists also question the relevance of certain findings, such as a protein-coding genes mRNA being produced in a brain region. After all, not all mRNAs are translated into proteins.
- [Evan] Eichler [U of Seattle] illustrates the challenges the field faces when he complains about spending the
past 5 years trying in vain to figure out the role of a promising family of genes that emerged
from his survey of segmental duplications.
All Pennisi could do at this point was highlight some of the latest studies trying to
establish the link. Each of them, however, suffers from the same weaknesses, as in the case
of a nerve protein named prodynorphin:
The prodynorphin example is one of the most advanced, but even this evolutionary story is unfinished,
because no one knows exactly what effect the extra prodynorphin has in the human brain, says [Greg] Wray
[Duke U]. And most other examples are in even earlier stages. In virtually all cases,
the link of genes or genomic patterns with human brain evolution is only tentative
and based on suggestive evidence, says Lahn.
The situation may not change anytime soon due to the complexity of the questions
and because we cant redo the experiment that evolution did in many millions of years.
And thats it: that is where the story of human brain evolution stands. Pennisi ended with
a short sentence pregnant with implications for science and society: Headline writers, pay heed.
That was just for starters in this series on genomics and evolution. Is the
situation any better in the story of eye evolution? Next....
- Eyes: Russell D. Fernald tried to cast Genetic Light on the Evolution of Eyes.3
His plot line is somewhat different, but certainly not a straight line from eyelessness to the best eyes.
The story invokes some common Darwinist words such as exploitation, convergence, and co-option that seem to
assume Darwinism rather than demonstrate it.
Light has been exploited for information by organisms through the evolution of photoreceptors and, ultimately, eyes in animals. Only a handful of eye types exist because the physics of light constrains photodetection. In the past few years, genetic tools have revealed several parallel pathways through which light guides behavior and have provided insights into the convergent evolution of eyes. The gene encoding opsin (the primary phototransduction protein) and some developmental genes had very early origins and were recruited repeatedly during eye evolution. Eye lens proteins arose separately and make up a diverse group, many of which were co-opted from other functions. A major challenge now is understanding how newly discovered pathways for processing light evolved and how they collaborate with eyes to harvest information from light.
Challenges to understanding are certainly not lacking in this field, either:
Understanding how eyes evolved into what Darwin called an organ of extreme
perfection requires analysis of evolutionary constraints, key selective forces,
and possible origins. The evolution of photodetection, giving rise to eyes,
offers a kaleidoscopic view of selection acting at both the organ and
molecular levels. The repeated exploitation of some regulatory gene sequences
in eye development and lens formation raises questions about why certain transcription factors
have been regularly recruited to build eyes. The ease with which we can now
analyze the evolution of structural gene sequences across species belies the difficulties
in tracing the selective forces that shaped regulation of gene expression.
His basic idea is that the physics of light constrains the evolution of eyes to what is
possible. This, however, begs the question of how an organism oblivious to the information
in light could care whether it exists, and whether a Darwinian mechanism could ever converge on a
constrained engineering solution to exploit that information and that not once, but multiple times.
Fernalds explanation seems to confuse cause and effect:
In using vision to extract information about the environment, all animals exploit
the same properties of light: intensity differences to produce contrast and wavelength differences to
produce hue. However, no unique solutions exist, and specializations that evolved
to process intensity and wavelength differ among species; these differences reflect how similar problems
are solved via diverse mechanisms through natural selection. For example, mammals
and bees use long wavelength photoreceptors for intensity and color vision, whereas flies and birds
have evolved separate sets of photoreceptors for these two purposes. The genetic substrates
that supported such different evolutionary paths are unknown. Even though blowfly and monkey
photoreceptors evolved independently and use different molecular mechanisms, signal
processing, and other physiological steps, the information about the world delivered to the
nervous system is nearly identical. These few examples reveal the different routes natural
selection has taken during the evolution of eyes in response to the information available in light.
As to actual studies linking genetic changes to evolution, its more of the same plot line
as that of brain evolution (above), but with a more convergent-evolution twist: for example,
Functionally, the exquisite gradient of refractive index necessary to allow
spherical lenses to focus light is a convergent solution that has evolved in
water-dwelling vertebrates and invertebrates alike. I.e., it evolved because it evolved.
Fernalds story is replete with the theme that if a source of information is available,
evolution will find a way to exploit it, even if we have no idea how it happened.
He ended, Light has been such an important source of information that evolution
has exploited it in many ways that remain to be discovered and understood.
Undoubtedly, a critic of evolution like Michael Behe, who wrote about the irreducible complexity of photoreception
in his book Darwins
Black Box, would remain unconvinced by such a statement.
- Heart: Is the story any different with heart evolution? Eric N. Olsen
wrote about this in the same issue of Science.4 He started out with
a flat assertion: The heart, an ancient organ and the first to form and function
during embryogenesis, evolved by the addition of new structures and functions to
a primitive pump. Embryogenesis, though, is not evolution, and is not controversial.
Can the heart really be explained by natural selection? The explanation sounds familiar:
Heart development is controlled by an evolutionarily conserved network of transcription
factors that connect signaling pathways with genes for muscle growth, patterning, and contractility.
During evolution, this ancestral gene network was expanded through gene duplication and co-option
of additional networks. Mutations in components of the cardiac gene network cause congenital
heart disease, the most common human birth defect. The consequences of such mutations
reveal the logic of organogenesis and the evolutionary origins of morphological complexity.
This line of explanation (duplication and co-option) is apparently a skeleton key to Olsen:
The modular addition of innovations to primitive structures,
although speculative, has also been proposed as a mechanism for the genesis
of other vertebrate organs and body structures. A proposal is not a proof.
Since the article is basically just elaboration on this theme, the interested
reader can refer to it for details. Suffice it to say he referred to evolutionary conserved
elements seven times, co-option five times, and duplication seven times (assuming gene duplication
provided the raw material for modular innovation). He used the word primitive eight times,
six of which refer to assumed ancestral hearts: e.g., in vertebrate embryos, Cardiac progenitors
from the primary heart field converge at the ventral midline to form a linear heart tube
that resembles, both structurally and functionally, the primitive heart thought to exist in
ancestral chordates. This could be a reference to Haeckels controversial
recapitulation theory, largely discredited by many of todays leading Darwinists.
As with the other articles, the complete evolutionary story will have to
be told in the future, he said, (though research continues to help advance medicine, whether or
not evolution is true).
Heres his last word: Further analysis of the genetic networks
that govern heart development through the combined use of genomics, genetics, and model
organisms promises to yield insights, not only into general principles of organogenesis,
but also to facilitate therapies for congenital and acquired heart disease.
- Developmental genes: Hox genes, implicated in body plan patterning during
embryonic development, have been suggested as sources of evolutionary innovation. Derek Lemons
and William McGinnis discussed this aspect of evolutionary genomics in their article.5
This, also, is no simple story:
Beginning with Lewis, there has been much speculation
that changes in Hox gene number may have contributed to morphological evolution.
Such ideas are a variation on the old theory that duplicating genes, particularly developmental
control genes, may be an initial step in a process that increases regulatory circuit complexity,
leading to increased morphological complexity, whereas elimination of control genes may be an
initial step leading to less morphological complexity. In one case, gene-replacement experiments
showed that two mammalian Hox paralogs have nearly identical functions in a variety of tissues,
which may be an example of a Hox duplication and functional divergence at an initial stage.
So all they could offer were speculative examples of these possible correlations.
On the other hand, they wrote (hinting of trouble ahead), adult sea urchins and
urochordate tunicates, which exhibit innovative and complex body architectures, have one set of
Hox genes, either scrambled or dispersed. Clearly it would be simplistic to
reduce all evolution to Hox gene duplication and divergence. Perhaps the
novelty of these adult morphologies is dependent on other, equally complex sets of regulatory genes
that resemble the Hox genes in their power to diversify morphology but are as yet not
well understood. This not only points to the complexity of the Hox gene
regulatory networks, but complicates the problem for evolutionists: there may be additional
networks, just as complex, that we dont even know about. The closing paragraph is
notable for its speculative words and lack of certainty:
There is currently no rigorous evidence that connects the loss or gain of specific Hox genes or gene complexes with specific morphological changes in different lineages, but there are a number of intriguing correlations.
Genomic analyses have revealed surprising diversity in Hox gene number,
organization, and expression patterns in different animals. There are still
many animal groups about which little genomic sequence is known, and it
remains to be seen how much more variation in Hox gene organization
and function will emerge, including the numbers and functions of non-protein-coding RNAs.
The property of HOX proteins working as a loosely coordinated system, often with
overlapping patterns of expression and function, has apparently fostered their abilities
to contribute to morphological change during the evolution of animals.
Their colinear [sic] arrangement and coordinated regulation in many animals may assist in
the maintenance of their overlapping expression patterns. This may have allowed
some members of the clusters to subtly and slowly alter their expression patterns
and functions to drive groups of cells toward novel structures. But Hox genes
still can work as an axial patterning system even when partially dispersed in the genome,
and dispersal may foster their rate of functional evolution.
- Tree of Life: The final article in the special series is Genomics and
the Tree of Life by Antonis Rokas.6 The lone photo in the article is Charles Darwins
sketch of a branching tree, a lovely tree as Rokas calls it, depicting
the path of evolutionary diversification through millions of years. Has genomics
confirmed Darwins picture? The dramatic increase in data set sizes has led,
in many cases, to increased confidence in the inference of evolutionary relationships,
he said. But then a few sentences later, the yardage on that first down was lost:
But further increases in data set sizes present challenges as well. Analyzing
many thousands of nucleotides for hundreds or thousands of species requires substantial computational
power to efficiently search among all possible trees. More sophisticated statistical
algorithms are also needed for discovering the trees best supported by the data.
Several clades of the Tree of Life, including the one of Metazoa, are proving difficult to
resolve too. Most parameters of sequence evolution vary across lineages. Slight
biasesamplified by the sheer volume of datacan potentially mislead
phylogenetic algorithms and provide high support for the wrong trees.
(Note: metazoa includes all multicelled organisms, from flatworms to humans; i.e., the entire
tree of plants and animals is proving difficult to resolve.)
It seems apparent that such a situation could lend itself to creative storytelling.
Rokas spoke of phylogenetic riddles and alternative markers in the genes,
one of which produced the discovery of several new clades such as the Pegasoferae,
which unexpectedly combines bats with horses, cats, dogs, and pangolins (see
But even the approach of looking at alternative markers is still in its infancy, he admitted.
Then there is the problem of lateral gene transfer. This writes off any hope of tracing a
phylogenetic tree for non-eukaryote one-celled organisms: the extensive occurrence of lateral gene
transfer in prokaryotes has raised concerns as to the validity of any
gene-based phylogenies for these organisms. These he called evolutionary
networks and not trees, although it is not clear how any kind of evolutionary lineage
could be inferred from this kind of scrambled egg. The only approach he offered (identification
of core orthologs) doesnt really solve the problem: However, given the prevalence
of lateral gene transfermostly in prokaryotes, to a much lesser extent in
eukaryotesas well as the high frequency of gene gain and loss, questions
as to whether these core gene sets are meaningful or how we can reliably identify orthology
among genes remain wide open. Indeed, The integration of genomics data
into the phylogenetics mold is just beginning. Interesting choice
of word: mold. What is a phylogenetics mold, if not an evolutionary stricture into which
the data must be fit? That this is the case he made clear in the next paragraph:
As the choice of genomes to be sequenced is increasingly guided by evolutionary
considerations, and as emerging sequencing technologies promise to drop costs even lower,
the reach and impact of genomics to non-model organisms is rapidly extending....
Given the breadth of organismal diversity, the gene-scale era of phylogenetics is still
an invaluable asset to the pursuit of the Tree if Life. Comparative genomics,
with its ability and potential to vastly increase both the amount and type of molecular data
available for a small but critical fraction of biodiversity, is bound to play an increasingly
important role in efforts to assemble a robust picture of the Tree of Life.
A bystander could well wonder which is the cart, and which is the horse.

If you have never gotten angry about the snow job that
professional evolutionists have pulled in science, you should be hopping mad now. We provided
plenty of quotations and links so that you can savor the baloney in all its rottenness.
A cursory glance at the cover, Building the Body from Genes, would give an
unsuspecting reader the impression that scientists are well on their way explaining all the most
complex features of our body the heart, eye, and brain by Darwins tall
tale. The caption boasts,
Back to beginning of this entry.
Through comparative genomics, scientists are learning about the forces that
have promoted diversity or imposed constraints on our biological machinery.
As described in a special section beginning on page 1907, comparative genomics
not only gives us a view of our evolutionary history but also illuminates human physiology
and suggests new approaches to attacking diseases.
Dont be fooled. The references to physiology and medicine are tossed in
as distractions to give an aura of undeserved legitimacy to the bankrupt
yarns of the Darwin Party, like perfume to mask B.O. (baloney odor).
You just read the real situation for yourself. Strip away the
paragraphs of impertinent details about what scientists in a laboratory have observed about real genes, i.e., all
the observational details irrelevant to evolution, and what is left? Only a house of cards
built out of hope, hype, assumption and wishful thinking. Not a single observational fact supported
their tale, and most of the facts were contrary to it. But since the stretch and squish theory of
molds itself to the most uncooperative facts, like The Blob to a bicycle, honest investigation
has come to a halt. Evolutionary theory is like a castle in the air, burdened down by facts that
would otherwise bring it crashing down to the ground, were it not for the continual stream of hot air
blown by Darwin Party windbags.
Yet this is the only theory allowed in our public schools, museums, national
parks, mainstream media, government-funded research institutions and (incredibly) many liberal churches.
How many classrooms will use the simplified charts, and come away with a completely false picture,
where all the facts fit neatly into a story with a happy ending? If you are still reading this,
you are one of the few to know the true situation. You thought this was Science, but now it is
clear that the Darwinists have been just making this stuff up as they go along and force-fitting it
into a plot that was determined by faith in their materialistic worldview. Facts be damned;
they are just props to The Endless Story, a fictional tale where machinery emerges by itself and
begins to think.
If you are sick and tired of the shenanigans the Darwin Party has pulled these 147 years, making
it seem like their story had triumphed over every other possible explanation, such that everybody
had to acquiesce to Charlie worship whether they liked it or not,
its time to call their bluff and demand accountability. Darwin did not lead us to
the Tree of Life, but to a Tree of Death millions of years of death and destruction,
out of which endless forms most beautiful emerged, they told us. Well, weve gotten nothing
for trusting these charlatans but endless promises of vaporware on back order. Bedtime storytime is over;
wispy dreams of convergent evolution have evaporated into the morning light;
Creation-Evolution Headlines has sounded the alarm, and were all wide awake now.

Congratulations for the 6th Anniversary. The work you do is very important.
Please dont ever give up. God bless the whole team.
(an engineer and computer consultant in Virginia)
I really appreciate your work in this topic, so you should never stop doing what you do,
cause you have a lot of readers out there, even in small countries in Europe, like Slovenia
is... I use crev.info for all my signatures on Internet forums etc., it really is fantastic site,
the best site! You see, we(your pleased readers) exist all over the world, so you must be
doing great work! Well i hope you have understand my bad english.
(a biology student in Slovenia)
Thanks for your time, effort, expertise, and humor. As a public school biology teacher I
peruse your site constantly for new information that will challenge evolutionary belief and share much
of what I learn with my students. Your site is pounding a huge dent in evolutions supposed
solid exterior. Keep it up.
(a biology teacher in the eastern USA)
Several years ago, I became aware of your Creation-Evolution Headlines web site.
For several years now, it has been one of my favorite internet sites. I many times check your
website first, before going on to check the secular news and other creation web sites.
I continue to be impressed with your writing and research skills, your humor,
and your technical and scientific knowledge and understanding. Your ability to cut through
the inconsequentials and zero in on the principle issues is one of the characteristics that
is a valuable asset....
I commend you for the completeness and thoroughness with which you provide
coverage of the issues. You obviously spend a great deal of time on this work.
It is apparent in ever so many ways.
Also, your background topics of logic and propaganda techniques have been useful
as classroom aides, helping others to learn to use their baloney detectors.
Through the years, I have directed many to your site. For their sake and mine,
I hope you will be able to continue providing this very important, very much needed, educational,
humorous, thought provoking work.
(an engineer in Missouri)
I am so glad I found your site. I love reading short blurbs about recent discoveries, etc,
and your commentary often highlights that the discovery can be interpreted in two differing ways,
and usually with the pro-God/Design viewpoint making more sense. Its such a refreshing difference
from the usual media spin. Often youll have a story up along with comment before the masses
even know about the story yet.
(a system administrator in Texas, who calls CEH the UnSpin Zone)
You are indeed the Rush Limbaugh Truth Detector of science falsely so-called.
Keep up the excellent work.
(a safety director in Michigan)
Just wanted to drop you a line to congratulate you on the 6th anniversary of Creation-Evolution headlines,
and to thank you once again for the laborious but necessary work that you do. I know of no better way to stay
informed with current scientific research than to read your site everyday, which in turn has helped me understand
many of the concepts not in my area (particle physics) and which I hear about in school or in the media.
Also, I just love the commentaries and the baloney detecting!!
(a grad student in particle physics)
I thank you for your ministry. May God bless you! You are doing great job effectively
exposing pagan lie of evolution. Among all known to me creation ministries [well-known organizations listed]
Creationsafaris stands unique thanks to qualitative survey and analysis of scientific publications and news.
I became permanent reader ever since discovered your site half a year ago. Moreover your ministry is
effective tool for intensive and deep education for cristians.
(a webmaster in Ukraine, seeking permission to translate CEH articles into Russian to reach
countries across the former Soviet Union)
The scholarship of the editors is unquestionable. The objectivity of the editors is
admirable in face of all the unfounded claims of evolutionists and Darwinists. The amount
of new data available each day on the site is phenomenal (I cant wait to see the next new
article each time I log on). Most importantly, the TRUTH is always and forever the primary
goal of the people who run this website. Thank you so very much for 6 years of consistent
dedication to the TRUTH.
(11 months earlier): I just completed reading each entry from each month. I found your site about
6 months ago and as soon as I understood the format, I just started at the very first entry
and started reading.... Your work has blessed my education and determination to bold in
showing the unscientific nature of evolution in general and Darwinism in particular.

Thanks for the showing courage in marching against a popular unproven unscientific belief system.
I dont think I missed 1 article in the past couple of years.

I do not know and cannot imagine how much time you must spend to read, research and
compile your analysis of current findings in almost every area of science. But I do know
I thank you for it.
(a practice administrator in Maryland)
Yes, it does take a lot of time, and it's lonely work. It is very encouraging when readers write and
say they benefit from this service.
Since finding your insightful comments some 18 or more months ago, Ive
visited your site daily.... You
so very adeptly and adroitly undress the emperor daily; so much so one
wonders if he might not soon catch cold and fall ill off his throne! ....
To you I wish much continued success and many more years of fun and
frolicking undoing the damage taxpayers are forced to fund through
unending story spinning by ideologically biased scientists.

I really like your articles. You do a fabulous job of cutting through
the double-talk and exposing the real issues. Thank you for your hard
work and diligence.
(an engineer in Texas)
I love your site. Found it about maybe
two years ago and I read it every day. I love the closing comments in
green. You have a real knack for exposing the toothless claims of the
evolutionists. Your comments are very helpful for many us who dont know
enough to respond to their claims. Thanks for your good work and keep it

Your insights ... been some of the most helpful not surprising considering the caliber of
your most-excellent website! Im serious, ..., your website has to be the
best creation website out there....
(a biologist and science writer in southern California)
I first learned of your web site on March 29.... Your site has far exceeded my expectations and is
consulted daily for the latest. I join with other readers in praising your time and energy spent to educate,
illuminate, expose errors.... The links are a great help in understanding the news items.
The archival structure is marvelous.... Your site brings back dignity to Science conducted as it
should be. Best regards for your continuing work and influence. Lives are being changed and
sustained every day.
(a manufacturing quality engineer in Mississippi)
I wrote you over three years ago letting you know how much I enjoyed your Creation-Evolution headlines,
as well as your Creation Safaris site. I stated then that I read your headlines and commentary every day,
and that is still true! My interest in many sites has come and gone over the years, but your site is
still at the top of my list! I am so thankful that you take the time to read and analyze some of the
scientific journals out there; which I dont have the time to read myself. Your commentary is very,
very much appreciated.
(a hike leader and nature-lover in Ontario, Canada)
...just wanted to say how much I admire your site and your writing.
Youre very insightful and have quite a broad range of knowledge.
Anyway, just wanted to say that I am a big fan!
(a PhD biochemist at a major university)
I love your site and syndicate your content on my church website....
The stories you highlight show the irrelevancy
of evolutionary theory and that evolutionists have perpetual foot and
mouth disease; doing a great job of discrediting themselves. Keep up
the good work.

I cant tell you how much I enjoy your article reviews on your
websiteits a HUGE asset!

Really, really, really a fantastic site. Your wit makes a razor appear dull!...
A million thanks for your site.
(a small business owner in Oregon and father of children who love your site too.)
Thank God for ... Creation
Evolution Headlines. This site is right at the cutting edge in the debate
over bio-origins and is crucial in working to undermine the
deceived mindset of naturalism. The arguments presented are unassailable
(all articles having first been thoroughly baloney detected) and the
narrative always lands just on the right side of the laymans comprehension
limits... Very highly recommended to all, especially, of course, to those who
have never thought to question the fact of evolution.
(a business owner in Somerset, UK)
I continue to note the difference between the dismal derogations of the darwinite devotees, opposed to the openness and
humor of rigorous, follow-the-evidence scientists on the Truth side. Keep up the great work.

Your material is clearly among the best I have ever read on evolution problems!
I hope a book is in the works!

I have enjoyed reading the sardonic apologetics on the Creation/Evolution Headlines section
of your web site. Keep up the good work!

I was grateful for creationsafaris.com for help with baloney detecting. I had read about
the fish-o-pod and wanted to see what you thought. Your comments were helpful and encouraged me
that my own baloney detecting skill are improving. I also enjoyed reading your reaction
to the article on evolution teachers doing battle with students.... I will ask my girls to read your
comments on the proper way to question their teachers.
(a home-schooling mom)
I just want to express how dissapointed [sic] I am in your website. Instead of being objective, the
website is entirely one sided, favoring creationism over evolution, as if the two are contradictory....
Did man and simien [sic] evovlve [sic] at random from a common ancestor? Or did God guide this evolution?
I dont know. But all things, including the laws of nature, originate from God....
To deny evolution is to deny Gods creation. To embrace evolution is to not only embrace his creation,
but to better appreciate it.
(a student in Saginaw, Michigan)
I immensely enjoy reading the Creation-Evolution Headlines. The way you use words
exposes the bankruptcy of the evolutionary worldview.

...standing O for crev.info.
(a database programmer in California)
Just wanted to say that I am thrilled to have found your website! Although I
regularly visit numerous creation/evolution sites, Ive found that many of them do
not stay current with relative information. I love the almost daily updates to
your headlines section. Ive since made it my browser home page, and have
recommended it to several of my friends. Absolutely great site!
(a network engineer in Florida)
After I heard about Creation-Evolution Headlines,
it soon became my favorite Evolution resource site on the web. I visit several times a
day cause I cant wait for the next update. Thats pathetic, I know ...
but not nearly as pathetic as Evolution, something you make completely obvious with your snappy,
intelligent commentary on scientific current events. It should be a textbook for science
classrooms around the country. You rock!

I set it [crev.info] up as my homepage. That way I am less likely to miss some really interesting events....
I really appreciate what you are doing with Creation-Evolution Headlines. I
tell everybody I think might be interested, to check it out.

Creation-Evolution Headlines is my favorite
anti-evolution website. With almost giddy anticipation, I check
it several times a week for the latest postings. May God bless you and
empower you to keep up this FANTASTIC work!

I read your pages on a daily basis and I would like to let you know
that your hard work has been a great help in increasing my knowledge
and growing in my faith. Besides the huge variety of scientific
disciplines covered, I also enormously enjoy your great sense of humor
and your creativity in wording your thoughts, which make reading your
website even more enjoyable.

I am an ardent reader of your site. I applaud your efforts and pass on
your website to all I talk to. I have recently given your web site info
to all my grandchildren to have them present it to their science
teachers.... Your Supporter and fan..God bless you all...
(a health services manager in Florida)
Why your readership keeps doubling: I came across your website at a time when I was just getting to know what creation science is all about. A friend of mine was telling me about what he had been finding out. I was highly skeptical and sought to read as many pro/con articles as I could find and vowed to be open-minded toward his seemingly crazy claims. At first I had no idea of the magnitude of research and information thats been going on. Now, Im simply overwhelmed by the sophistication and availability of scientific research and information on what I now know to be the truth about creation.
Your website was one of dozens that I found in my search. Now, there are only a handful of sites I check every day. Yours is at the top of my list... I find your news page to be the most insightful and well-written of the creation news blogs out there. The quick wit, baloney detector, in-depth scientific knowledge you bring to the table and the superb writing style on your site has kept me interested in the day-to-day happenings of what is clearly a growing movement. Your site ... has given me a place to point them toward to find out more and realize that theyve been missing a huge volume of information when it comes to the creation-evolution issue.
Another thing I really like about this site is the links to articles in science journals and news references. That helps me get a better picture of what you're talking about.... Keep it up and I promise to send as many people as will listen to this website and others.

Im a small town newspaper editor in southwest Wyoming. Were pretty
isolated, and finding your site was a great as finding a gold mine. I read
it daily, and if theres nothing new, I re-read everything. I follow links.
I read the Scientist of the Month. Its the best site Ive run across. Our
local school board is all Darwinist and determined to remain that way.

Congratulations on your 5th anniversary. I have been reading your page for about 2 years or so....
I read it every day. I ...am well educated, with a BA in Applied Physics
from Harvard and an MBA in Finance from Wharton.
(a reader in Delaware)
I came across your website by accident about 4 months ago and look at it every day....
About 8 months ago I was reading a letter to the editor of the Seattle Times that was written
by a staunch anti-Creationist and it sparked my interest enough to research the
topic and within a week I was yelling, my whole lifes education has been a lie!!!
Ive put more study into Biblical Creation in the last 8 months than any other topic in my life.
Past that, through resources like your website...Ive been able to convince my father (professional mathematician and amateur geologist), my best friend (mechanical engineer and fellow USAF Academy Grad/Creation Science nutcase), my pastor (he was the hardest to crack), and many others to realize the Truth of Creation.... Resources like your website help the rest of us at the grassroots level drum up interest in the subject. And regardless of what the major media says: Creationism is spreading like wildfire, so please keep your website going to help fan the flames.
(an Air Force Academy graduate and officer)
I love your site! I **really** enjoy reading it for several specific reasons: 1.It uses the latest (as in this month!) research as a launch pad for opinion; for years I have searched for this from a creation science viewpoint, and now, Ive found it. 2. You have balanced fun with this topic. This is hugely valuable! Smug Christianity is ugly, and I dont perceive that attitude in your comments. 3. I enjoy the expansive breadth of scientific news that you cover. 4. I am not a trained scientist but I know evolutionary bologna/(boloney) when I see it; you help me to see it. I really appreciate this.

I love your site. Thats why I was more than happy to
mention it in the local paper.... I mentioned your site as the place

I use the internet a lot to catch up on news back
home and also to read up on the creation-evolution controversy, one of my favourite topics.
Your site is always my first port of call for the latest news and views and I really appreciate
the work you put into keeping it up to date and all the helpful links you provide. You are a
beacon of light for anyone who wants to hear frank, honest conclusions instead of the usual diluted
garbage we are spoon-fed by the media.... Keep up the good work and know that youre changing lives.

[Creation-Evolution Headlines] is the place to go for late-breaking
news [on origins]; it has the most information and the quickest turnaround.
Its incredible I dont know how you do it.
I cant believe all the articles you find. God bless you!
(a radio producer in Riverside, CA)
Just thought I let you know how much I enjoy
reading your Headlines section. I really appreciate
how you are keeping your ear to the ground in so
many different areas. It seems that there is almost
no scientific discipline that has been unaffected
by Darwins Folly.
(a programmer in aerospace from Gardena, CA)
I enjoy reading the comments on news articles on your site very much. It is incredible
how much refuse is being published in several scientific fields regarding evolution.
It is good to notice that the efforts of true scientists have an increasing influence at schools,
but also in the media.... May God bless your efforts and open the eyes of the blinded evolutionists
and the general public that are being deceived by pseudo-scientists.... I enjoy the site very much
and I highly respect the work you and the team are doing to spread the truth.
(an ebusiness manager in the Netherlands)
I discovered your site through a link at certain website...
It has greatly helped me being updated with the latest development in science and with
critical comments from you. I also love your baloney detector
and in fact have translated some part of the baloney detector into our language (Indonesian).
I plan to translate them all for my friends so as to empower them.

I found your site several months ago and within weeks
had gone through your entire archives.... I check in several times a day for further
information and am always excited to read the new
articles. Your insight into the difference between
what is actually known versus what is reported has
given me the confidence to stand up for what I
believe. I always felt there was more to the story,
and your articles have given me the tools to read
through the hype....
You are an invaluable help and I commend your efforts.
Keep up the great work.
(a sound technician in Alberta)
I discovered your site (through a link from a blog) a few weeks ago and I cant stop reading it....
I also enjoy your insightful and humorous commentary at the end of each story. If the evolutionists
blindness wasnt so sad, I would laugh harder.
I have a masters degree in mechanical engineering from a leading University. When I read the descriptions, see the pictures, and watch the movies of the inner workings of the cell, Im absolutely amazed.... Thanks for bringing these amazing stories daily. Keep up the good work.

I stumbled across your site several months ago and have
been reading it practically daily. I enjoy the inter-links
to previous material as well as the links to the quoted
research. I've been in head-to-head debate with a
materialist for over a year now. Evolution is just one of
those debates. Your site is among others that have been a
real help in expanding my understanding.

I was in the April 28, 2005 issue of Nature [see 04/27/2005
story] regarding the rise of intelligent design in the universities. It was through your website
that I began my journey out of the crisis of faith which was mentioned in that article. It was an honor to see you all highlighting the article in Nature. Thank you for all you have done!
(Salvador Cordova, George Mason University)
I shudder to think of the many ways in which you mislead readers, encouraging them to build a faith based on misunderstanding and ignorance. Why dont you allow people to have a faith that is grounded in a fuller understanding of the world?...
Your website is a sham.
(a co-author of the paper reviewed in the 12/03/2003
entry who did not appreciate the unflattering commentary. This led to a cordial
interchange, but he could not divorce his reasoning from the science vs. faith dichotomy,
and resulted in an impasse over definitions but, at least, a more mutually respectful dialogue.
He never did explain how his paper supported Darwinian macroevolution. He just claimed
evolution is a fact.)
I absolutely love creation-evolution news. As a Finnish university student very
interested in science, I frequent your site to find out about all the new science
stuff thats been happening you have such a knack for finding all this
information! I have been able to stump evolutionists with knowledge gleaned from
your site many times.

I have spent quite a few hours at Creation Evolution Headlines in the past week
or so going over every article in the archives. I thank you for such an informative

Ive had your Creation/Evolution Headlines site on my favourites list for
18 months now, and I can truthfully say that its one of the best on the Internet,
and I check in several times a week. The constant stream of new information on
such a variety of science issues should impress anyone, but the rigorous and
humourous way that every thought is taken captive is inspiring. Im pleased
that some Christians, and indeed, some webmasters, are devoting themselves to
producing real content that leaves the reader in a better state than when they found him.
(a community safety manager in England)
I really appreciate the effort that you are making to provide the public with
information about the problems with the General Theory of Evolution. It gives me

Answering your invitation for thoughts on your site is not difficult because
of the excellent commentary I find. Because of the breadth and depth of erudition
apparent in the commentaries, I hope Im not being presumptuous in suspecting
the existence of contributions from a Truth Underground comprised of
dissident college faculty, teachers, scientists, and engineers. If thats
not the case, then it is surely a potential only waiting to be realized. Regardless,
I remain in awe of the care taken in decomposing the evolutionary cant that bombards
us from the specialist as well as popular press.

I wholeheartedly agree with you when you say that science is not
hostile towards religion. It is the dogmatically religious that are
unwaveringly hostile towards any kind of science which threatens their
dearly-held precepts. Science (real, open-minded science) is not
interested in theological navel-gazing.

Featured Creation Scientist for September
This months great scientist is a character from ancient history,
predating even the Greeks by a long shot. Yet in many
ways, he exceeded them all.
He was a veritable philosopher-king, a many-talented
individual with a reputation that is legendary to this day.
He was a mineralogist, taxonomist, botanist, zoologist, ornithologist,
ichthyologist, and entomologist. His writings even convey
an understanding of thermodynamics and the
hydrologic cycle principles that are not always intuitively
obvious long before they were rediscovered in the 19th century.
And though a religious man (at times), he was one of the
earliest practitioners of
what is known today as methodological naturalism (at least
until he got older and wiser).
Although records of his scientific work are scanty, they are
intriguing. They provide a glimpse into what must have
been a profound analytical mind. His photographic memory
was phenomenal. He seems to have taken special interest in
gymnosperms and angiosperms; we know that he was an expert on
Cedrus libani and Origanum syriacum, but probably
hundreds more between these extremes; he cultivated many varieties of plants
in his own experimental arboreta. In fact,
he was sufficiently wealthy to employ a small army of lab
assistants, not only in his gardens, but his ranches and
zoos. He was particularly fond of Equus, collecting
an extensive assortment of specimens.
Exotic mammals and birds imported from distant lands were
a special hobby in which he delighted.
We know that this scientist published a great deal; unfortunately,
only tantalizing fragments and short biographical references remain.
But in his day, his reputation spread far and wide; fellow
scientists and intellectuals travelled great distances to
converse with and learn from him. We can easily imagine that he had a
large retinue of students and disciples.
This scientist was one of the first to approach the study of
natural phenomena mechanistically. You might say he was
a naturalist naturalist, using two diverse
meanings of the word side by side:
he loved nature, but approached his systematic study and
classification of phenomena without reference to spiritual
or miraculous elements. In other words, though he was a
theist, not a philosophical naturalist, he
practiced methodological naturalism in his
scientific approach. Apparently this served him well, for
a time. It provided him a great deal of satisfaction and
motivation to classify things, describe them, and learn about
them. He also sought to understand their underlying causes and
build theories: he said, I applied my heart to know,
To search and seek out wisdom and the reason of things.
He apparently felt no need for what we would call today creationism
or intelligent design thinking, except in a general sense (he was not
an atheist, after all).
Yet in his later years, his thinking underwent a dramatic reversal.
Over time, this scientist began to despair of ever really achieving
a unified theory or even believing that getting a substantial grasp
on science was even possible. He lost interest in the
particulars and became more concerned with general principles;
less stamp-collecting and more philosophy, in other words.
One of his fundamental conclusions sounds remarkably like Godels
Theorem, i.e., that it is impossible to establish the validity
of system without reference to external axioms.
Contemplation of this principle, and his increasing dissatisfaction
with collecting and publishing the minutiae,
gradually opened his mind to his own inadequacy, and the
absolute requirement to build on the foundation of divine
revelation. He became a creationist.
Have you figured out who we are talking about? His name
is Solomon. King Solomon, richest man of his day and
wisest man who ever lived (with a wisdom given him by God),
is often overlooked as a scientist. But I Kings 4 says
he spoke of trees, from the cedar of Lebanon
to the hyssop that springs out of the wall; he spoke also of
animals, of birds, of creeping things, and of fish.
From the context, these are clearly the meagerest of samples.
Kings and dignitaries from around the world came to hear the
wisdom and knowledge of Solomon. In his book
Ecclesiastes, the summation of his old-age philosophical
musings, he recalls some of his earlier efforts in horticulture,
ranching, engineering and architecture.
The Proverbs of Solomon are frequently peppered with animal and plant
allusions that provide glimpses into his natural knowledge,
which must have been encyclopedic. He enjoyed the exotic
gifts foreign dignitaries would bring, including apes and peacocks.
Living in peacetime with unlimited wealth, he was almost
single-handedly responsible for
the greatest scientific renaissance the world had ever seen.
The theistic (Hebrew) world view that permitted Solomon to view
the work as a great machine or puzzle to be solved also permitted
Solomon to get wrapped up in his own efforts. That is why
he seemed to approach his science and all his works
as under the sun a grievous task given by God
to mankind, devoid of meaning, purpose, and value when approached
without reference to the Creator. Under the sun
is analogous to methodological naturalism: the pursuit of knowledge
for its own sake, forgetting the Creator, trying to figure it all
out by human effort. Solomon eventually realized it cannot
Thus his famous phrase, Vanity of vanities: all is
Solomon never lost his love for nature, but realized that there is
more to it than meets the eye. There is a spiritual element
to man that resists naturalistic explanation, and that there are
purposes we can never know in and of ourselves.
He [God] has made everything beautiful in its time. Also He
has put eternity in their hearts, except that no one can find out
the work that God does from beginning to end (Eccl. 3:11).
For the logical positivist who thinks there is no limit to scientific
inquiry, he speaks from experience: When I applied my heart to know
wisdom and to see the business that is done on earth, even
though one sees no sleep day or night, then I saw all the work of
God, that a man cannot find out the work that is done under the sun.
For though a man labors to discover it, yet he will not find it;
moreover, though a wise man attempts to know it, he will not be able
to find it (Eccl. 8:16-17). Todays scientists
would do well to avoid trying to hoe that row again, unless they
think they can reach infinity.
So after years of self-centered searching for knowledge,
Solomon came to his senses and rearranged his priorities.
He decided that much study is a weariness of the flesh, and
of the making of many books there is no end. He called
his final anthropic principle the whole duty of man (Eccl. 12):
Fear God, and keep His commandments. In other words,
realize that natural revelation without special revelation is
pointless and ultimately dissatisfying.
For aspiring scientists young enough to avoid his mistake, he has sober
advice: Remember now your Creator in the days of your youth.

Creation Scientists from Y1K to Y2K.
A Concise Guide|
You can observe a lot by just watching.
First Law of Scientific Progress
The advance of science can be measured by the rate at which exceptions to previously held laws accumulate.
1. Exceptions always outnumber rules.
2. There are always exceptions to established exceptions.
3. By the time one masters the exceptions, no one recalls the rules to which they apply.
Nature will tell you a direct lie if she can.
So will Darwinists.
Science is true. Dont be misled by facts.
Finagles 2nd Law
No matter what the anticipated result, there
will always be someone eager to (a) misinterpret it, (b) fake it, or (c)
believe it happened according to his own pet theory.
3. Draw your curves, then plot your data.
4. In case of doubt, make it sound convincing.
6. Do not believe in miracles rely on them.
Murphys Law of Research
Enough research will tend to support your theory.
If the facts do not conform to the theory, they must be disposed of.
1. The bigger the theory, the better.
2. The experiments may be considered a success if no more than 50%
of the observed measurements must be discarded to obtain a correspondence
with the theory.
The number of different hypotheses erected to explain a given biological phenomenon
is inversely proportional to the available knowledge.
All great discoveries are made by mistake.
The greater the funding, the longer it takes to make the mistake.
The solution to a problem changes the nature of the problem.
Peters Law of Evolution
Competence always contains the seed of incompetence.
An expert is a person who avoids the small errors while sweeping on to the grand fallacy.
Repetition does not establish validity.
What really matters is the name you succeed in imposing on the facts not the facts themselves.
For every action, there is an equal and opposite criticism.
Thumbs Second Postulate
An easily-understood, workable falsehood is more useful than a complex, incomprehensible truth.
There is nothing so small that it cant be blown out of proportion
Hawkins Theory of Progress
Progress does not consist in replacing a theory that is wrong
with one that is right. It consists
in replacing a theory that is wrong with one that is more subtly wrong.
The best theory is not ipso facto a good theory.
Error is often more earnest than truth.
Advice from Paul|
Guard what was committed to your trust, avoiding the profane and idle
babblings and contradictions of what is falsely called knowledge by
professing it some have strayed concerning the faith.
I Timothy 6:20-21
Song of the True Scientist
O Lord, how manifold are Your works! In wisdom You have made
them all. The earth is full of Your possessions . . . . May the glory of the Lord endure forever. May the
Lord rejoice in His works . . . . I will sing to the Lord s long as I live; I will sing praise to my God while I have my
being. May my meditation be sweet to Him; I will be glad in the Lord. May sinners be
consumed from the earth, and the wicked be no more. Bless the Lord, O my soul! Praise the Lord!
from Psalm 104
Through the creatures Thou hast made
Show the brightness of Thy glory.
Be eternal truth displayed
In their substance transitory.
Till green earth and ocean hoary,
Massy rock and tender blade,
Tell the same unending story:
We are truth in form arrayed.
Teach me thus Thy works to read,
That my faith, new strength accruing
May from world to world proceed,
Wisdoms fruitful search pursuing
Till, thy truth my mind imbuing,
I proclaim the eternal Creed
Oft the glorious theme renewing,
God our Lord is God indeed.
James Clerk Maxwell
One of the greatest physicists
of all time (a creationist).
