How Best to Propagate Darwins Science 05/31/2007

Two book reviews recently discussed the problem of scientific illiteracy in society,
which the authors equated with doubts about Darwinian evolution.
- Dumb public: In a review in
Science
of A Scientists Guide to Talking to the Media by
Richard Hayes and Daniel Grossman (Rutgers, 2006), Barbara Kline Pope began with an anecdote to illustrate
the pitiful state of scientific literacy in America. She had overheard a lady in a doctors office
waiting room saying, Well, I can sort of believe in evolution, but I just cant see that the
big bang really happened. Kline was appalled at this example of the dismal state of
scientific literacy. She pointed to evolution and the big bang as some of the most
established scientific theories. It was not clear, however, what connection these two theories had with the
rest of her review, which focused on the theme that knowledge of basic scientific ideas is necessary
for adequate citizen participation in decision-making, preparation for employment, and the practical
aspects of daily life. How many include the big bang in their job applications, or evolutionary
theory in their town hall meetings?
- Group conundrum: In
Nature,
Mark Pagel gave a surprisingly unenthusiastic review of David Sloan
Wilsons Evolution for Everyone: How Darwins Theory Can Change the Way We Think About Our Lives
(Delacorte Press, 2007; see entry from 11/01/2005). He left it
doubtful this book will convince anyone to become an evolutionist.
Like the previous review, this one bemoaned why so few people accept Darwins
theory. Its a source of endless frustration to evolutionary biologists that the
number of doubters remains high: currently 54% up from 46% in 1994. One answer might be that creationists are
having more kids. The other answer, however, is the tack Sloan Wilson prefers: evolutionists just
havent done a good enough selling job: if the evidence
for darwinian evolution is presented clearly enough and often enough, any reasonable person will come
around to the darwinian view. But Pagel realizes this will be a hard sell to human-type primates:
What is there to say? The usual answer, that we share more than 98% of our genes with chimpanzees,
is becoming hackneyed. It is the strangeness of human behaviour that really puts the darwinian
view to the test. And here there is much to discuss. We have enormous brains that make us
shrewd beyond belief in comparison to other animals, we have the only fully developed symbolic language
on the planet, we cooperate with and engage in elaborate task-sharing and reciprocal relations
with people we dont know, we help the elderly, give money to charities, put on matching silly
shirts to attend football matches, obediently wait in queues, die for our countries or even sometimes for an
idea, and we positively ripple and snort with righteousness and indignation when we think others
dont do some of these things. We even have a word for this sense of how others ought to behave
morality. Chimpanzees, and for that matter other animals, arent like this. No wonder
the creationists dont believe the darwinian account.
Though Pagel called
it an agreeable little book, he thought Sloan Wilson oversold the group-selectionist view of
human sociality. For every example of evolutionary altruism, Pagel had counter-examples of selfish
individualism. If group selection is so effective, he puzzled, why do bees with much smaller brains do a better job of
cooperation than humans, if we have enjoyed such big brains for 3.5 million years? With the Darwinists
themselves still debating whether human altruism can be explained by group selection or individual selection,
he considered Sloan Wilsons approach too optimistic.
And at this point, we award Mark Pagel Stupid Evolution Quote of the Week for his ending logical
conundrum:
But perhaps even Sloan Wilson should not expect to change peoples minds about religion.
If our minds evolved to help us wade through the complexity of social life, to use groups for our
own gain, and to help us rebound from the slings and arrows of outrageous fortune, which
set of beliefs, on balance, will be more useful, religious ones (whether true or not) or a belief
in natural selection?
This seems to be saying that if evolution invented religion, it must be useful, so dont knock
it. But then why even try to convince anyone that a useless idea like natural selection is true?
A bigger conundrum is raised by Pagels quote: how did
the evolutionary biologists figure out natural selections conspiracy to hide the truth from everyone else?
Maybe they are the ones that are deceived. How could they tell? There is no truth in Darwinland.
There is no standard of usefulness, either; i.e., useful to whom? Is survival even useful?
Whatever useful means, it appears evolutionists arent very useful themselves.
Maybe they are just mutants that need to be selected away from the gene pool. How ironic. By pushing
a useless theory called Darwinism, they won themselves a
Darwin Award.
We need a new category: Evil Evolution Quote of the Week. The rabid atheist
Sam Harris was at it again, as Madelaine Bunting wrote for the
Mail&Guardian
online. Lumping Christians and radical Muslims in the same category, Harris pondered,
some propositions are so dangerous that it may even be ethical to kill people for
believing them. What constitutes an atheistic standard of ethics, he did not say.
Vicki Baker used this quote for a pop quiz on the
Dangerous Intersection blog.
It prompted a variety of heated responses. Apparently, Sam Harris never quite got around
to realizing this has already been tried (see 11/30/2005
entry).

Dumb Ideas
Molecular Motors Move You 05/30/2007

The realization that cells are filled with molecules that move like machines fascinates many
people. Students who grew up thinking of chemistry as bouncing molecules that did little
more than link up and separate have a whole new paradigm to consider: molecules that walk,
fold and unfold, spin and operate like ratchets, robots, wrenches and motors. Here are
a few recent developments in the world of molecular machines:
- Brownian walk: Researchers in Science1 reported that myosin,
a molecular walking motor used in muscle, harnesses the random force of Brownian
motion to keep on track. Brownian motion is the random shuddering action of small molecules due
to thermal motion in the environment. Like sails in the wind, myosin motors are built in such a way that they can make
use of the vector component corresponding to the direction they need to go. The leading
neck swings unidirectionally forward, whereas the trailing neck, once lifted, undergoes extensive
Brownian rotation in all directions before landing on a site ahead of the leading head,
said Shiroguchi and Kinosita. The neck-neck joint is essentially free, and the neck
motion supports a mechanism where the active swing of the leading neck biases the random motion
of the lifted head to let it eventually land on a forward site. This way they get a
push for free. The authors did not discuss how this mechanism might have evolved.
- Gut-level machinery: Speaking of myosin, did you know it aids digestion?
Your digestive tract is lined with microvilli, tiny projections that vastly increase the surface area
of the intestinal membrane that absorbs nutrients. Now, scientists have found theres a lot
more going on in the tips of these projections.
Science Daily reported
on work at Vanderbilt that showed myosin is concentrated in the tips and appears actively involved
in shedding membrane material at the tips. This process of vesicle formation and detachment
may inject metabolic enzymes into the passing food material, as well as protect the lining of the
intestine from invaders. Its all done with motors: myosin 1a, a protein with the
potential to generate force and move cargo around in cells. Matthew
Tyska figured that there must be a reason these force-generating motors are concentrated in the
microvilli, and sure enough, he found them at work: Its a little machine that can
shed membrane from the tips, he said. This could give a whole new dimension to the
term bowel movement. Now his group is seeing if a similar mechanism
operates in other cellular projections, like the hair cells of the inner ear.
See also EurekAlert.
- Clockworks: A paper in Nature discussed the latest research into the molecular
mechanisms behind biological clocks.2 There is not one clock molecule involved, but a host of
proteins that form feedback loops in cycles that express and repress certain genes in response to
environmental cues. One of the proteins is even nicknamed CLOCK. The article payed
particular attention to PGC-1-alpha, a protein that appears intimately linked to both the circadian
rhythm and metabolism, affecting the production of glucose, fatty acids and haem (iron-containing
molecules). Many questions remain, however. This is clearly a work in progress.
- Splice and dice: Another paper in Nature used the word machinery
six times, speaking of the spliceosome.3 A complex macromolecular machinery in
the nucleus of eukaryotic cells is responsible for pre-mRNA splicing, said Blencowe and Khanna.
They described how alternative splicing is a remarkably efficient mechanism for a cell to increase
the structural and functional diversity of its proteins, and it plays many roles in gene regulation
(see 05/20/2007). The way alternative splicing is controlled
is by RNA riboswitches, including messenger-RNA transcripts that can regulate their own
expression with feedback and feed-forward loops. These riboswitches can actually change shape
in response to cues, and the shape determines how the gene will be expressed. The authors used
the word switch 18 times.
Earlier, riboswitches
were thought to exist only in bacteria and fungi, but now it appears they may be common in higher
animals and in plants. The authors speculated about evolutions place in this:
It seems plausible that splicing-regulatory riboswitches represent a system that has
evolved to coordinately regulate multiple genes in the same biochemical pathway using
feedback and, in some cases, feed-forward mechanisms, they asserted. Presumably, the
rapid kinetics and energy-saving advantages afforded by bypassing protein-mediated regulation
explain why riboswitch aptamers have persisted during evolution and function at many levels of
regulation of gene expression. Yet this seems to assume what needs to be proved.
They used the presence of these switches, and the advantages they appear to confer, as evidence they
evolved, yet provided no details on how that could have occurred by natural selection. By
contrast, the evidence they did provide shows the opposite of evolution: between very distant organisms,
like fungi and higher plants, the genes involved are evolutionarily conserved
(i.e., unevolved).
- Machine language: Two scientists publishing in PNAS sounded like factory
planners, but were talking about cells.4 Experimental and theoretical studies of
proteins, acting as motors, ion pumps, or channels, and enzymes, show that their operation
involves functional conformational motions, they said. A few sentences later,
the machine talk continued: Generally, a machine is a mechanical device that performs
ordered internal motions that are robust against external perturbations. They were
discussing how molecular machines in the cell, particularly myosin and ATP synthase, are examples of
such robustness. In conclusion, they said in the final discussion section,
we have shown that motor proteins possess unique dynamical properties, intrinsically related to
their functioning as machines. This recalls a line Scott Minnich said in the film
Unlocking the Mystery of Life: Its not convenient that we give them these [machine] names;
its truly their function.
Part of the title read, design principles of molecular machines.
Yet the authors attributed this design to undirected chance processes of evolution in this
statement: Actual proteins with specific architectures allowing robust machine operation may
have developed through a natural biological evolution, with the selection favoring such special
dynamical properties. They ran a simulation of an evolutionary computer
optimization process and achieved a artificial elastic network architectures
possessing machine-like properties, but this statement blurs the line between intelligently-selected
outcomes and chance.
Machine language is quite common in the scientific literature. One often finds
matter-of-fact discussion of proteins and enzymes as machines. They use energy and perform
physical work according to tight specifications. The evolutionary conundrum is: how could
functioning machines arise from non-functional matter in motion? Authors of scientific papers
typically either ignore the question, or assume evolution did the design work.
A more fruitful approach was offered by a biophysicist who wrote Nature last week,
suggesting that we Look at biological systems through an engineers eye.5
R. S. Eisenberg said that when approaching a black box, whether an amplifier in a sound system or an
unknown mechanism in a living cell, we should identify the inputs and outputs, the power supply and
the device equation. Looking at biological devices with the eyes of an engineer, he said,
can lead to fruitful experiments:
Complex systems for example, with many internal nonlinear connections like the
integrated circuit modules of digital computers or, perhaps, the central nervous system
may not be easily analysed as devices, no matter how many experimental data are available.
But it seems clear, at least to a physiologist, that productive research is catalysed by assuming that
most biological systems are devices. Thinking today of your biological preparation as a device
tells you what experiments to do tomorrow.
Asking the questions in this way leads to the design of useful experiments that
may eventually lead to the device description or equation, if it exists. If no device description
emerges after extensive investigation of a biological system, one can look for other, more subtle descriptions
of natures machines.
An intelligent design scientist might feel vindicated. No evolutionary theorizing is needed in
this approach. Assuming design in the device, and asking engineering questions, can stimulate a
fruitful experimental program.

These papers speak for themselves. Was anybody impressed
by the evolutionary storytelling? Was it useful? Did it contribute to understanding
in any way? How about, on the other hand, the machine language? Can you talk machine
language without assuming intelligent design? Where do you think science is headed?
Bye-bye, Charlie.

Resisting Science, or Resisting Purposelessness? 05/29/2007

Why do so many adults resist science?, asked Yale psychologists Paul Bloom and Deena Skolnick Weisberg
in an essay on The Edge.
They argued that childhood common sense impressions lead to a teleological view of the world.
These impressions conflict with evolutionary ideas presented at school, but are reinforced
by religious authorities. The job of the teacher, then is to help them overcome their
natural proclivities toward design thinking. They ended,
Given the role of trust in social learning, it is particularly worrying that national surveys
reflect a general decline in the extent to which people trust scientists. To end on a practical
note, then, one way to combat resistance to science is to persuade children and adults that the
institute of science is, for the most part, worthy of trust.
Dr. Albert Mohler launched into a commentary on this essay on his blog for
May 29.
He joked, The attorney who asks a jury, What are you going to believe, my argument
or what you see with your own eyes?, has a fool for a client. More seriously,
he turned the tables on Bloom and Weisberg: Many polls indicate that a majority of Americans
reject the dominant evolutionary theory and believe in some form of divine creation. This
frustrates the evolutionary scientists to no end. But they are asking Americans to reject
what they learned in Sunday School in favor of a theory that insists that the universe is a great
cosmic accident. Its not just children whose brains are hard-wired to reject that.
This interchange provides some good food for thought, but
before digesting it, add this antacid: what on earth do Bloom and Weisberg mean by science,
anyway? Sounds like they could use a purpose-driven life instead of a life divorced of purpose.

Ant Brain: Software Compression Extreme 05/28/2007

How can so much software fit in such a small space? An ant brain cant be very
big, but look what it can do. The BBC
News and Science Daily both told
about the route-finding ability of army ants. Not only do they find the most efficient routes to their
targets, they even plug potholes with their own bodies. The volunteers that agree to get
walked on, providing a living surface for the others, are even specifically matched
to the size of the hole, scientists at University of Bristol found. One team member said,
When it comes to rapid road repairs, the ants have their own do-it-yourself highways agency.
In addition, ants are able to plan far ahead for their own workforce.
Science Daily reported
that ants, one of natures ultimate self-organising species breeds optimum numbers of
each worker type to ensure the smooth running of the colony. They seem to have an
uncanny sense to adjust the expression of key genes to breed the workforce that will be
most in demand in the future. How they do this is a mystery, but one evolutionary biologist
was certain Darwin could explain it: It seems that ants have evolved their own solution to this problem.
Do-it-yourself agency, he said. Self-organizing species,
they called it. Do ants have a sense of
self? Do they complain when they get walked on, like people do? Just a momentary
jest; whatever is going on, a lot of information has to be packed into a tiny space in the head
of an ant. The miniature robots know just what to do and do it extremely well (see
09/12/2001).
And what do you know, they say army ants have been doing this for 100 million years without any evolution
(05/06/2003, 11/14/2000). What do you know.
Notice how in this and the next entry, evolutionists are fond of phrasing their
materialistic theory in the personal, active verb form: such-and-such evolved a solution,
or color vision, or whatever. Foul! The organism did not and could not conspire to
do such a thing. Their own presuppositions disallow it. Dont let an evolutionist
confuse the issues with such personal,
teleological language. Force them to be consistent. This will poke a hole that will leak all the pneuma
out of their theorys tires. Simultaneously, their explanations will be seen not as highways, but as potholes, wider than
their own bodies. Flat tires on a highway that is all pothole and no road will get their theory nowhere fast,
even if they all join hands and feet in a desperate attempt to keep the road from disappearing. (As if
that would help, anyway; they dont even know where their road should go.)

Red Vision Produced Red Hair in Monkeys 05/27/2007

Daily thought so, and so did Live
Science, which said, A new study shows that apes first evolved color vision to help
them forage food, after which nature made red the sexiest color around and spiked apes
evolutionary tree with red hair and skin. Monkey see red, monkey do red.
If there was a 650-nanometer photon around but nobody

Creation Museum Opens 05/26/2007

The $27 million Creation Museum in Florence, Kentucky, built by
Answers
in Genesis, opened to the public on May 26, after years of planning and construction.
It features audio-animatronic dinosaurs, a planetarium, a bookstore, hiking trails and
many elaborate exhibits.
AIG unashamedly presents a Biblical interpretation of origins, science,
history and ultimate destiny of man and the universe within a Genesis timescale.
The entire project was financed by private donations.
The New York Times
printed a surprisingly favorable review of the museum by Edward Rothstein. His only
critical question was as follows:
The other catastrophe, in the museums view, is of more recent vintage: the abandonment of the
Bible by church figures who began to treat the story of creation as if it were merely metaphorical,
and by Enlightenment philosophers, who chipped away at biblical authority. The ministry believes
this is a slippery slope....
But one problem is that scientific activity presumes that the material world is
organized according to unchanging laws, while biblical fundamentalism presumes that those laws
are themselves subject to disruption and miracle. Is not that a slippery slope as well, even
affecting these analyses?
Nevertheless, Rothstein seemed impressed by the experience of walking through the elaborate
dioramas. The visitor, he said, leaves feeling a bit like Adam emerging from Eden, all
the world before him, freshly amazed at its strangeness and extravagant peculiarities.
The answer to Rothstein, of course, is that the Darwinists believe in miracles,
too (see 05/24/2007). Their miracles are more
fantastic and unnatural than anything the Bible ever said. So pick your miracle-worker:
a God who has infinite power and intelligence, or time and chance. And, for extra consideration,
choose the bottom of the slippery slope you would like to live at: a world of hate, sin, strife and
evil, or a world that abides by the moral laws of the Divine lawgiver. Science did pretty well
for centuries before atheists co-opted it for their agenda. Read what Madelaine Bunting
wrote recently about the new hate-filled atheists in
Mail&Guardian
Online. Want to follow their lead?
A regular reader who visited on opening day may provide another
first-hand account soon. In the meantime, watch how the media react to this (and media from
around the world were on hand to practice their spinning skills). Some Darwinista
organizations, as we said
(05/23/2007), are trying to prevent people from going. AIG said that on
opening day a protest group with a rock band set up camp nearby. Here are the typical
spins you are bound to see:
- This is bad science and will make America fall behind the world.
- This museum is brainwashing kids.
- Cant we all just get along?
Monday evening 5/28, Fox News already interviewed an evolutionist using all three against AIG president Ken Ham.
There is only one word you need to know to respond to Darwiniacs who try to use these
ploys. HYPOCRISY.

Stupid Evolution Quote of the Week: Design by Darwin 05/24/2007

Can Darwin get credit for intelligently-planned research? Apparently John Chaput
thinks so. A press release from the
Biodesign Institute at Arizona
State University states this:
Nature, through the trial and error of evolution, has discovered a vast
diversity of life from what can only presumed to have been a primordial pool of building
blocks. Inspired by this success, a new Biodesign Institute research
team, led by John Chaput, is now trying to mimic the process of Darwinian evolution in
the laboratory by evolving new proteins from scratch. Using new tricks of molecular
biology, Chaput and co-workers have evolved several new proteins in a fraction
of the 3 billion years it took nature.
A strange mix of chance and design permeates the article, with evolve or evolution
17 times and design seven times. The Biodesign
Institute itself, according to its information page, seeks to learn from natures designs,
as do Caltech (06/25/2005) and the Georgia Institute of Technology
(10/29/2005).
The inspiration for such ventures is credited to evolution:
Research in the Institute shares a common starting point. It explores the remarkable structure and
function of living systems, which have been honed by thousands of years of evolution and natural selection.
If man could duplicate what nature does routinely, all aspects of society would be transformed....
The list of hopes is impressive: preventive health care, increase in the global food supply, brain repair
and industrial efficiency. Its all tied together in this sentence: The Biodesign
reference in our name reflects a desire to design solutions with the same efficiency and success as living
systems. But those, it goes without repeating, presumably evolved by chance over millions of years.
The Darwin Dogma of Miracles can be summarized: (1) assume
evolution, (2) personify Nature, and (3) wave the magic wand of millions
of years. Then, miracles of exquisite design occur by natural law. (Contradiction intended
for ironic, dramatic effect.)
The Intelligent Design movement should sue for trademark infringement,
plagiarism, and copyright violations when Biomimetics credits the Darwin Party.
Design belongs to intelligent minds, not trial-and-error outcomes of blind, impersonal processes.
How many times do we have to educate the Darwinists and reporters that guided evolution is
a contradiction in terms? That artificial selection is not natural selection, but
intelligent design?
When Dr. Chaput has a goal, designs the parameters, and makes a selection with his mind, he is
exercising intelligent design by definition. Darwin has nothing to do with it.
Mother Nature is a fiction, OK? Give honor to whom honor is due.
Good grief, the next thing well see the Darwinists doing is offering prayers and
sacrifices at the foot of idols of Mother Nature. At least that would be more sensible
than talking this way in a science lab. Recall a worse example by Francisco Ayala earlier this month
(05/10/2007).

Darwinists Combat Creation Displays in Advance 05/23/2007

Even before opening day, pro-evolution groups are launching pre-emptive strikes against
a new $27 million creation museum in Kentucky.
Fox News
reported that Eugenie Scotts National Center for Science Education has sent a petition to
600 scientists in the region to oppose the new museum. Also, the Campaign to Defend the
Constitution is calling the new museum a campaign by the religious right to inject
creationist teachings into science education.
Ken Ham, president of the museums builder Answers in Genesis,
counters that the vast majority of natural history museums and textbooks available to
students are devoted to teaching evolution so it seems odd that they would be worried
about one museum with a different message (see 10/17/2005). Opening day is May 28. The museum does
not inject itself into schools. Visitors have to come to the museum and pay an admission fee.
For the museums response to the NCSE, visit the
AIG website.
The Calgary
Herald reported about another creation museum opening in Alberta on June 5: the
Big Valley Creation Science Museum. As expected, the museum has its detractors,
the article states. Critics quoted in this article were a little less dogmatic, in that
they defended the right of people to weigh evidence and make up their own minds, but one
biology professor called it a propaganda approach and another said that
refuting evolution entirely was a little head in the sand.
Watch for fireworks in the media when the Creation Museum
opens. Evolutionists can have their lying feathered dinosaur displays (05/06/2004) and
their lying early-man displays (03/27/2007,
02/07/2007), often paid for with tax dollars to the tune of tens
of millions, but let a little alternative science be displayed and the Darwin Attack Dogs
come barking and snarling to scare people from entering. The contest in the media
should be interesting to watch. How many reporters will dredge up tired old talking
points and play the warfare-of-science-and-religion card? How many will acknowledge
the freedom and basic intelligence of people to weigh evidence and
make up their own minds? Anticipate some juicy Stupid Evolution Quotes of the Week.

Dino Feathers or Horsefeathers? 05/23/2007

The much-touted feathers on certain dinosaurs may be nothing more than collagen fibers.
An article on ABC France
says Dinosaur feathers are no such thing. Instead, its just
decayed dermal collagen, like that found on sharks and reptiles. A South African team came to
this conclusion after analyzing the alleged feathers on Sinosauropteryx.
If their analysis is correct, this casts
doubt on the birds-from-dinosaurs theory. The team lead called the idea a reckless
leap from the evidence, and said, There is not a single close-up representation of the
integumental structure alleged to be a proto-feather. He called for more scientific
rigor in the analysis of these fossils.
Nature Science Update
also reported on this find, saying Bald dino casts doubt on feather theory. It says,
If Sinosauropteryx was indeed featherless, then it may be that feathers arrived on the evolutionary scene later than palaeontologists had thought. But Nature downplayed the implications.
David Unwin, paleontologist at the University of Leicester,
said,theres no need to panic about the implications of this find. He claimed,
This doesnt in any way challenge the idea that dinosaurs had feathers and that dinosaurs
gave rise to birds. It just throws into doubt the first step in feather evolution.
But Unwin echoed a common theme in evolutionary theories: Things may be more complex than we thought.
PhysOrg was more dramatic.
It said that this announcement had the effect of a thunderclap on scientists who had used
the alleged feathers as evidence for bird evolution. Palaeontologists have fired a broadside
over a fossil which is the cornerstone evidence to back the theory that birds descended from dinosaurs.
Although we dont want to make a conclusion based on one
teams analysis of one fossil, we agree more scientific rigor is called for. Notice how
Nature was quick to hedge about the meaning of this disillusionment. The rest of the media that
love to display artists reconstructions of feathered dinosaurs are strangely silent so far.
We ought to be asking seriously, in the meantime, have we been sold a bill of goods (again) about feathered
dinosaurs? (10/10/2005,
05/06/2004). We have often seen the propensity of the
Darwinists to take flights of fancy based on lightweight evidence
(cf. 02/08/2006, 09/27/2000).

Darwins Ethics: All and/or None 05/22/2007

Several stories recently indicate that evolutionists not only want to control the non-tangible
areas of study, such as ethics and morals, they want to prevent anyone else from having a say.
- Psychology: License to sin What would you think of a scientist who
tempted people to sin so that he could observe their actions? Yet that is what a team
did to students, as reported by EurekAlert.
They found that asking people to think about vice increases their likelihood of giving in.
This should raise red flags about the ethics and limits of science.
- Theology: Drosophila philosophy Believe it or not, an article on
EurekAlert asks
whether fruit flies have free will. The article, about a study published on PLoS One,
ponders what combination of chance and necessity (and only those ingredients) can explain the
flys behavior. Free will vs determinism has long been an issue discussed by
theologians and philosophers. Now, biologists are thinking they can give the definitive word.
Presumably, what applies to fruit flies applies to people as well.
- Genetic engineering: Age of the chimera The
BBC News reported that the British
government has bowed to pressure from scientists and overturned prohibitions against human-animal
hybrid experimentation. An ethicist called this appalling and said,
This is a highly controversial and terrifying proposal, which has little justification in
science and even less in ethics. Endorsement by the UK government will elicit horror in
Europe and right across the wider world.
Proponents advertised hoped-for cures for genetic diseases, and argued it was an area where
these [chimeras] could be used for scientific benefit. According to
The Guardian (UK), a
geneticist said Im delighted that common sense has prevailed, calling the hybrids
just cells on a dish.
- Education: Warning signs The scientific press is sounding an alarm: a
Darwin skeptic who was on the Kansas school board is now running unopposed for a post in Washington

Daily had only negative things to say about this development. It has many evolution advocates
concerned, and Ken Miller (Brown U) responded, any situation that provides an opportunity for
the opponents of science education to advance their agenda is a matter of concern.
This presupposes the Darwin supporters have no agenda. It also asserts without proof that candidate
Kenneth R. Willard opposes science education completely, and that only pro-evolutionists are in
favor of science education. If appointed, Kenneth R. Willard would not even start serving till January 2009.
He said in the Hutchinson News that
evolution is not on the agenda of the NASBE, and he does not expect to bring it up. Nevertheless, activists
with Kansas Citizens for Science are urging a write-in campaign to oppose his election on the grounds he is
anti-education.
- Education: Litmus Test Astrobiologist Guillermo Gonzalez, co-author of
The Privileged Planet, was denied tenure at Iowa State
last week, not because he lacked publications (he exceeded the requirement by 350%), or because his scientific work
was substandard (it was acclaimed by peers, see
Evolution
News), but because he is a Darwin skeptic who supports intelligent design.
The news about his tenure denial was widely reported: for more information, see
Evolution News and
its review of report
in Nature on the case.
- History: Darwin letters opened Want to read the innermost thoughts of Charles
Darwin? His letters have been posted on the web, announced the
BBC News.
- Ideology: Biopolitics Can evolutionary theory bring an end to the
clash of ideologies? Apparently psychologist John Jost (New York U) thinks so. He is persuading
colleagues that human tendencies to embrace various ideologies can be analyzed with equations.
See story on EurekAlert.
- Propaganda: Anti-evolutionism as anti-science An article in
Science1 tried to analyze the childhood origins of adult anti-science behavior.
Paul Bloom and Deena Skolnick Weisberg considered creationism and resistance to evolutionary theory as
examples of anti-scientific attitudes, and portrayed them as childish behaviors that were not properly
overcome through education. Surprisingly, they admitted that common sense contributes to resistance
to evolution.
They ended, This is the current situation in the United States, with regard to
the central tenets of neuroscience and evolutionary biology. These concepts clash with intuitive beliefs
about the immaterial nature of the soul and the purposeful design of humans and other animals, and
(in the United States) these beliefs are particularly likely to be endorsed and transmitted by trusted
religious and political authorities. The idea is that scientists and educators need to be
aware of these anti-science tendencies in their efforts to teach science a science
that is congruent with materialistic neuroscience and evolution.
At Access
Research Network, David Tyler wrote a lengthy critique of this article from an intelligent design perspective.
- Emotions: Darwin book redux Another paper in Science2 resembled
Darwins Book The Expression of Emotion in Man and Animals and even included the 1872 book as
a reference. In Embodying Emotion, Paula Niedenthal gave physicalistic interpretations
of emotions in people and in animals. Though she did not refer to evolutionary theory directly,
her paper also lacked any reference to anything like a soul or spirit. She said,
In particular, I discuss insights that have been stimulated by theories of embodied cognition and
show how such theories account for the embodiment effects that you and Darwin might have been able to intuit.
- Morals: Biological morality Jonathan Haidt got a full-page press in Science3
for his ideas on moral evolution (see 05/17/2007). More research is needed on the collective and religious parts of the moral domain, such as loyalty, authority, and spiritual purity, he said,
but it is clear in his paper that he meant all these things have an evolutionary basis, and zero epistemic
authority.
For instance,
he said, From prokaryotes to eukaryotes, from single-celled organisms to plants and animals, and from
individual animals to hives, colonies, and cooperative groups, the simple rules of Darwinian evolution
never change, but the complex game of life changes when radically new kinds of players take the field.
From here he launched into a discussion of the morality exhibited by ants.
Later, he remarked,
because morality may be as much a product of cultural evolution as genetic evolution, it can change
substantially in a generation or two. Thats a clear statement of moral relativism. Throughout his
paper, evolution was one of the most prominent and common words.
These sample articles make clear that evolution is a complete package. From a big bang to the death
of the universe, the evolutionary world view seeks to encompass every concept, even the immaterial ones like
love, morality, and world views themselves. When anyone tries to offer a different perspective that
does not embrace evolutions underlying materialism, the alarms are sounded. Pro-evolutionists
employ scientific morality, whatever it is, to label the challenge anti-science, anti-education,
and just plain wrong.

And so, pray tell, how would they know it is wrong?
Right and wrong are judgments about truths that are immaterial. If morals emerge from
particles in motion, they are not morals at all: they are temporary, arbitrary trends of collectives of objects.
If you base an argument on something arbitrary, you can prove anything including the
idea that materialism is false. Christian theists, by contrast, can prove something is right
or wrong, because their presuppositions include the notion of eternal truths and laws of logic.
Evolutionism is not a science. It is a world view.
It is a silly world view that refutes itself, because it cannot
generate intangibles like morals and truths by appeals to particles in motion.
Any one of the appeals to science that the evolutionist uses to
defend its brand of morality, rationality or ideology is a two-edged sword. Using the same
arguments, a skilled debater can turn the tables and tie the Darwinist in intellectual knots.
For instance, moral relativism is a capitulation to the idea that anything goes. But if anything
goes, then calling anything immoral in any context is bad if the majority likes it such as
creationism. Furthermore, attacking moral relativism itself can be good if the majority so desires which refutes
the idea that morals are relative. Q.E.D.
You cant get moral blood out of a materialist turnip. The same goes for truths, laws
of logic, and consciousness.
Once you understand this, and watch how the radical Darwinists intrude
into every area of scholarship, including fundamental issues far beyond biology, you see why the
radical Darwinists are a threat: a threat to rationality, to morality,
to education, and to civilization itself. Their own words condemn them.

Think Fast: News Briefs 05/21/2007

Of the many news items that cross the CEH desk, many are noteworthy but go unreported due to lack of time.
Here are a few that deserve honorable mention lest they pass into oblivion.
- Cosmology: Dark future Several sources like
Science Now and
Space.com commented
on the dark future of the universe if cosmic acceleration continues to tear the universe apart.
Its not just a heat death any more. Hundreds of billions of years from now, the story goes,
galaxies will recede from our horizon, making us feel very alone before we freeze to death.
Christians might find it interesting to compare this eschatology with their own.
- Astronomy: Venerable star Is this star really 13.2 billion
years old? Thats what scientists at ESA
said (see also National
Geographic). They called a star in our Milky Way a galactic fossil and claim it was born not long
after the big bang. The fact that it contains heavy elements means that, according to theory, even
earlier stars had to form first, live, die and explode to provide the ingredients.
The dating methods are indirect, naturally. Stars dont have birth certificates.
Nobody seemed to question the estimate.
- Cell biology: Tar babies Imagine cells that can thrive in gooey asphalt.
Thats what biologists have found in the famed La Brea Tar Pits in Los Angeles, reported
EurekAlert.
- Zoology: Frog pharmacy Why would God create highly poisonous frogs?
Maybe He didnt. An article on National
Geographic says that the poison on frog skin, made of alkaloids, comes from mites they eat.
Certain species of frogs seem to have been able to tolerate the alkaloids and shuttle them onto their
skin. The mites pick up the alkaloids from leaf litter. Some frogs end up tasting bitter,
and some are highly poisonous. The toxicity, therefore, may have been a consequence of a natural
concentrating process that did not add any new information to the genome of the frogs or the mites.
In a related story, National
Geographic said that juices in frog skin might provide an ideal bug repellant. The reporter wrote,
frog skin is really a portable pharmacy full of chemicals for keeping the amphibians healthy.
- Planetary science: Enceladus friction a new theory for how Enceladus produces
geysers was offered in Nature and echoed in
EurekAlert,
National Geographic
and Space.com.
The idea is that tidal forces open and close the tiger stripes or cracks in the southern
hemisphere, producing heat like rubbing your hands together. This might permit a geysering
mechanism without water (which, National Geographic lamented, might decrease the odds for life).
The paper did not address how long this mechanism could last, nor why the other nearby moons are not
so affected.
- Genetics: Music of the proteins Someone at UCLA decided to put proteins to
music, reported EurekAlert.
The website allows visitors
to download MP3 files and listen to them. Amino acids were assigned chord values and the sequences
were played in tune. Listeners can judge whether this makes any scientific sense.
- Climate: Global historic warming Evidence for a megadrought in the
12th century has been deduced from tree rings in the Colorado Plateau, reported
EurekAlert.
The U of Arizona researcher was surprised by how deep and long it lasted. He said it
could be an analogue for what we could expect in a warmer world. It is doubtful
the American Indians were burning coal and gasoline at the time, so dont blame them.
Incidentally, prolonged droughts have been suggested as reasons for the decline of the Anasazi.
Their cliffside remains scattered throughout the southwestern United States were left abandoned en masse.
- Marine biology: Cold treasure trove Scientists were amazed to find a rich,
diverse ecology under Antarctic ice. The
Live Science article was published
widely. Evolutionists thought that harsh environments would produce less biodiversity.
See also the National
Geographic report with pictures.
- Marine biology: Demise greatly exaggerated Another Coelacanth was pulled up
in Indonesia, reported PhysOrg.
This classic living fossil species that was thought to have gone extinct in the time
of the dinosaurs was found alive in 1938. Since coelacanths live in deep, cold waters, they normally
do not survive after capture for more than a couple of hours. This one lived 17 hours. Their bony fins, once
thought to be evolving into limbs for land travel, are used for swimming:
The powerful predator is highly mobile with limb-like fins, and it gives birth to live young
rather than laying eggs. The report in
National Geographic
has a photo of the fish and fisherman.
This shows just a little of the material that must be sifted to bring you Creation-Evolution

Genetics: Alternate Reading Frames May Be Common 05/20/2007

Imagine a book written in a language where there were no spaces, and every word was
three letters long. Now imagine that you could get one story by starting at
the first letter, and a different story by starting at the second letter, and another by starting at the third letter.
Thats the situation with some genes in the genetic code. DNA can code for one
protein in the first reading frame, but a different protein in an alternate reading frame.
Since the DNA language has three nucleotide letters per codon word,
and since the opposite strand has three more reading frames, there are potentially six
reading frames per gene. How commonly are alternate reading frames used by an organism?
A paper in PLoS Computational Biology hints that there may be widespread examples
of alternate reading frames (ARFs) in mammalian genomes. ARFs were thought to be rare
in eukaryotes. An international team, using new statistical techniques, found 40
cases in the human genome, but says that this may be a significant underestimate, since their
analysis was very conservative. Their authors summary asks and answers why these
alternate reading frames were not found before:
A textbook human gene encodes a protein using a single reading frame.
Alternative splicing brings some variation to that picture, but the notion of a single
reading frame remains. Although this is true for most of our genes, there are exceptions.
Like viral counterparts, some eukaryotic genes produce structurally unrelated proteins from overlapping
reading frames. The examples are spectacular (G-protein alpha subunit [Gnas1] or INK4a
tumor suppressor), but scarce. The scarcity is anthropogenic in origin: we simply do not
believe that dual-coding genes can occur in eukaryotes. To challenge this assumption,
we performed the first genome-wide scan for mammalian genes containing alternative reading
frames located out of frame relative to the annotated protein-coding region. Using a newly developed
statistical framework, we identified 40 such genes. Because our approach is very conservative,
this number is likely a significant underestimate, and future studies will identify more
alternative reading frame-containing genes with fascinating biology.
They said there was an almost zero probability these ARFs
were due to chance: in fact, one section of the paper is subtitled, Dual Coding Is Virtually
Impossible by Chance. Finding so many ARFs was surprising, they said, because maintaining
ARFs by natural selection is costly i.e., mutations in one reading frame could
disable the information in the alternate frame.
Often, the proteins that result from alternate reading frames are related to
the same function or process in the cell. The researchers compared the well-known ARFs between
humans, mice and some other mammals and found them to be highly conserved (i.e., unevolved).

Try writing a message that could be read three different ways
depending on which letter was the starting point. It is extremely difficult.
If this turns out to be a common mechanism in genetics, it reveals an astonishing level of
intelligent design. How, and why, would a blind process do such a thing? Notice how
geneticists were not even looking for this amount of complexity because they did not believe it
was possible.
This technique of data compression could expand the functional information of the
genome significantly. ARF! The hunt is on. Sic the design community on this fascinating puzzle.
They wont be tied up and muzzled from announcing the return of the Master to biology.

Speaking of conserved genes, remember the mystery of the ultraconserved elements?
The 05/27/2004 entry describes thousands of frozen
strands of DNA with no change between animals as distinct as birds and humans.
Furthermore, not all the ultraconserved elements were in gene-coding regions, and some
are apparently not required for survival.
This announcement produced gasps of amazement among geneticists.
Science Is for the Birds 05/19/2007

Birds, with all their variety and functionality, are a never-ending source of study for
scientists. Here are some recent feathery findings:
- Memory masters: Scrub jays are like us: they can plan ahead, regardless
of mood. Current Biology did
a study that proved these common western birds can cache tomorrows breakfast
regardless of their motivational state. The authors said, The fact that the birds
act in favor of a future need as opposed to the current one challenges the hypothesis that
this ability is unique to humans.
- Lab masters: A Nevada scientist wrote
Science about
his backyard experience watching his labrador retriever trying to match wits with a crow.
When the dog would get too close to the crows cache, the bird would grab it and move it
to a new location. Watching this regular ritual of food hiding and searching,
he quipped, The crow relied on his memory of his stashed food to beat the
dog to the prize nearly every time.
- Whoops, no sexual selection here: A textbook example of sexual selection
has been called into doubt. Current
Biology reported that the longer tails of male barn swallows are not just for attracting mates.
They apparently are due to naturally selected variation in the aerodynamic optimum for each individual
in other words, they have a function for the males flying behavior.
See also the original paper.
- Whoops, co-evolution in trouble: Elisabeth Pennisi in
Science described a
situation in which co-evolution has apparently stalled out, and is not a simple arms-race
kind of story. Clarks nutcrackers and the pine cones they feed on are in a more
complex situation when the squirrel factor is considered. Ecologists have found that,
in organisms from birds to bacteria, coevolution is not a sure thing, she said,
describing nagging inconsistencies in the observations.
- Rabbit terror: National Geographic had a one-page description of South
Americas terror birds, known only from fossils. These 7-foot monsters
with scary-looking beaks could have outrun an Olympic sprinter, the article by
Peter Gwin says. They were likely driven to extinction when a land bridge from North America allowed big
cats, dogs and bears to enter their territory Despite the artists illustration of the
big bird closing in on a terrified man, Gwin said they likely chased down rabbits (not humans) for food.
In Current Biology, Nicola Clayton
described how fascination with birds led to his career in determining the intelligence behind
their songs: I have always been fascinated by birds, especially by how their minds work and
why they engage in such amazing behavioural displays. Watching birds triggers my two passions: science and dance!
What does a 7-foot, 250-pound terror bird say? (Deep voice)
Polly want a rabbit, NOW! Humans call them terror birds,
but who knows; maybe they were as silly as turkeys. Its
hard to infer behavior from bones. There are living birds dangerous to man, though; the cassowary
can run fast and deliver a disembowelling kick to a human unlucky enough to intrude on its territory.
Thank goodness most birds are cute little things without Alfred Hitchcock conspiracies lurking in
their highly intelligent brains.
Watch the classic nature film Winged Migration to get your
passions triggered about birds. Our feathered friends are an endless source of fascination with their amazing abilities to
fly, swim, run, sing, dance, and communicate with a high degree of intelligence. Think of the tremendous
variety between a terror bird and a hummingbird: visualize penguins
(09/10/2004), condors, swans, egrets, kiwis, pigeons,
toucans, woodpeckers, spoonbills, doves
(09/09/2004), albatross, chickadees, birds of paradise,
flamingos, ostriches
(08/17/2004), swifts (04/29/2007), cormorants
(05/24/2004), parrots, majestic
eagles, owls, and many more. Birds have mastered and adorned the sea, the land and the skies.
Think how many birds add music to the world. How does a little lightweight critter
project its voice over the range of half a mile?
Sing Listen to the mockingbird and then do it. Think; what amazing intelligence lies behind this ability to sing
a rapid-fire repertoire of dozens of unique, complex melodies for hours? Evolutionists are up a tree
even with their textbook cases. Each month it seems they have to scuttle a previous story.
Do a good deed; teach your parrot to say Charlie was a slacker; birds believe in God.

Batting for Stupid Evolution Quote of the Week 05/18/2007

National
Geographic reported that bats are master flyers, whose aerodynamic skills outperform
birds.1 They also have an exquisitely refined sonar sense that allows them to discern
detail as fine as a fish fin sticking out of the water. Coupled with aerobatics and
see-in-the-dark sonar, a bat can swoop down and catch the fish right out of the water.
There is a feature story in the June
National Geographic Magazine
on the bats of Panama. It shows photographs of bats that can fish, catch insects, and
feed on fruit. The first fossil bat was already capable of powered flight
(04/20/2006, bullet 2). There is no evidence,
fossil or genetic, for how they arose from a non-flying mammal (01/28/2005).
This did not stop Jennifer Holland from inventing an evolutionary story out of thin air:
Sixty million years ago, on a planet crawling with mammals, one tree dweller rose above the
crowd on paper thin wings. So goes the story of ancestral bats, which, equipped with
flight and a sixth sense called echolocation, mastered the night sky and flourished.
(NG June 2007, p. 142).
Holland did not mention who the ancestral bats were, or what evidence she had for their existence.
Her tale sounds like an instantaneous evolution of multiple, complete, complex, interacting systems.
It also avoids explaining how this one tree dweller, so well-equipped with new equipment, could have
mated and produced fertile offspring.

Can Morality Be Evolutionized? 05/17/2007

A psychologist at the University
of Virginia is probing the evolutionary origins of morality:
[Jonathan] Haidt shows how evolutionary, neurological and social-psychological insights are
being synthesized in support of three principles: 1) Intuitive primacy, which says that human
emotions and gut feelings generally drive our moral judgments; 2) Moral thinking if [sic]
for social doing, which says that we engage in moral reasoning not to figure out the truth,
but to persuade other people of our virtue or to influence them to support us; and 3)
Morality binds and builds, which says that morality and gossip were crucial for the evolution
of human ultrasociality, which allows humans but no other primates to live in
large and highly cooperative groups.
Putting these three principles together forces us to re-evaluate many
of our most cherished notions about ourselves, says Haidt....
Haidt argues that human morality is a cultural construction built on top of and constrained by
a small set of evolved psychological systems....
We all start off with the same evolved moral capacities, says Haidt,
but then we each learn only a subset of the available human virtues and values.
We often end up demonizing people with different political ideologies because of our
inability to appreciate the moral motives operating on the other side of a conflict.
We are surrounded by moral conflicts, on the personal level, the national level and the
international level. The recent scientific advances in moral psychology can help
explain why these conflicts are so passionate and so intractable. An understanding of
moral psychology can also point to some new ways to bridge these divides, to appeal to
hearts and minds on both sides of a conflict.
Moral psychology is thus squarely built on the notion that morality itself is a product of
evolution not a reflection of universal truths or ideals of right vs. wrong. The article says Haidts
ideas represent a new consensus scientists are reaching on the origins and mechanisms of morality.
Apparently some even think ones world view is an evolutionary artifact. In a related story posted by
EurekAlert,
psychologists at New York University are probing the evolutionary origins of ideology.

Take a Walk in the Biodiversity Park 05/16/2007

A walk in the park is good for your spirit. That much we already knew.
Researchers at the University
of Sheffield now claim, though, that the more biodiversity in the park, the better:
Dr Richard Fuller and colleagues from the Universitys Department of Animal and
Plant Sciences, and De Montfort University in Leicester, have been able to show that
biologically complex surroundings appear to enhance a persons well-being more
than those spaces less rich in species.
Urban planners and city citizens should place value on preserving open space
near town, accessible to people.
The most biodiverse parks of all are the natural ones.
An urban park with all oaks and grass is better than nothing, but how about trying one
with dozens of species of trees and herbaceous plants and a variety of birds and wild animals?

OOL Study Substitutes Computer for Chemistry 05/15/2007

Upon reading a recent origin-of-life paper in PNAS,1 you might think the authors
ran experiments with real chemicals and real deep-sea rocks. A more careful look, however,
reveals that their model only worked in cyberspace. This raises interesting questions about
the ability of simulations to substitute for empirical evidence.
Their claims were dramatic accumulation of the building blocks of life by
factors of 100 million and more. The paper makes optimistic, if not enthusiastic, claims that nucleotides
and other important biochemicals can be highly concentrated in micropores in deep-sea geological
formations: We find that interlinked mineral pores in a thermal gradient provide a compelling
high-concentration starting point for the molecular evolution of life. This, they advertised,
can overcome the concentration problem that has plagued other models: how does one get
a significant number of prebiotic chemicals close enough together to interact?
From the first-sentence reference to Miller and Urey,
who used real lab apparatus and real chemicals, the paper appeared to follow the experimental tradition.
It focused on the problem of concentrating chemicals in a plausible environment.
By positing convection currents inside microscopic pores of rocks around deep-sea vents, the model
overcame by at least two orders of magnitude a minimum set by the Second Law
of Thermodynamics on how many molecules are needed for interaction to be considered probable.
True, the authors used the word simulated in the title and 14 times in the paper.
Their references to nucleotides and other real chemicals were qualified with indirect references.
Nevertheless, until the
Materials and Methods section at the end of the paper, it seemed they were talking about real
chemicals and physical pores in real rocks. One of the figures showed photographs from real hydrothermal
vents. They mentioned nucleotides 37 times including the title.
The body of the paper was filled with references to temperatures, pressures, volumes, and concentrations
that looked real. Actually, the entire model was done within two software programs,
Comsol and Femlab. The nucleotides, pores, and thermometers were virtual, not physical.
They tried to plug in real-world values into the programs and use
realistic boundary conditions. They input known properties of real molecules. Putative pore sizes were based on
photographs of real hydrothermal vents. The bottom line, though, is that
none of the concentration results were observed or measured in the wild.2 The model revolved around simplified
geometries of pores as programmed into a computer and that, of pores in only two dimensions.
Here was their concluding paragraph. Note the lack of reference to a computer simulation. Is it real,
or is it memo tricks?
In conclusion, we propose a type of mechanism, driven solely
by a temperature gradient, which strongly accumulates even
small protobiological molecules in semiclosed hydrothermal
pore systems. This setting provides a compelling, dissipative
microenvironment to promote the first steps in the molecular
evolution of life.
The line between real and virtual was blurred in another passing thought near the end of the paper:
Equally, freshly precipitated mesoscopic mineral grains are
subjected to thermal cycling by the convection. Their catalytic
surfaces might generate nucleic acid multimers by thermally
triggered periodic condensation and unbinding reactions. In
this context, we note that, in a comparable thermal convection
setting, DNA was shown to replicate exponentially by using the,
albeit protein-catalyzed, PCR.
Critics of origin-of-life studies might be stunned at this line. PCR, or polymerase chain reaction, is an
intelligently-guided reaction, performed by machines in laboratories by scientists with PhDs. PCR depends
on protein catalysts
highly complex molecules from living systems, whose specificity enables them to react with DNA.
By associating
a guided process that uses complex biological parts with a theoretical process that is unguided and uses simple
abiological parts, can the one be properly compared to the other without
assuming what needs to be proved the origin of complex
biological processes?
This paper was presented as part of a colloquium by the National Academy of Sciences last December
on In the Light of Evolution I: Adaptation and Complex Design (see 05/10/2007
entry), published May 9 on the Proceedings website.
1Baaske, Weinert, Duhr, Lemke, Russell and Braun, Extreme accumulation of nucleotides
in simulated hydrothermal pore systems,
Proceedings of the National Academy of Sciences
USA, 10.1073/pnas.0609592104, published online before print May 9, 2007.
2In addition, they did not test complications, such as whether pores might become clogged with tar and
sediments they just speculated and dismissed the possibilities, viz: One may ask whether the strong
accumulation of solvated organic molecules would lead to the tarring of the pore. This is
not expected because thermophoretic coefficients become small for concentrations in the molar range.
Models are OK, and have a long history in science, but the bluffing-to-proof
ratio in this paper was beyond the pale. These authors might be able to defend it by claiming they said it
was just a simulation in a computer, but nobody scanning the contents
would think so. Few readers are going to look at the Materials and Methods section (usually
boring, unless youre trying to replicate the results). This paper gave every appearance of being an empirical,
laboratory experiment in the real world. It was all done with software smoke and model mirrors.
As we saw 12/03/2004, one of the conspirators (Russell) is
a master bluffer. He has a propensity to gloss over major problems and swap out experimental facts for cartoon pictures on a
screen. In his 2004 lecture, he made everything look so simple, so problem-free, life should just pop out of
the pore. If life by the yard is hard, and life by the inch is a cinch, wouldnt life by the micron
be right on? Its a foregone conclusion. The hard part over, little Poregum would just gloriously
evolve into us. Some unbiased, objective scientist he is. He should read Shapiros devastating
critique (02/15/2007) of such notions.
Observational facts have a way of tarring up computer models. Let us ask a simple question: where are these
nucleotides supposed to get their ribose? Doesnt Russell and gang know that deep-sea vents
are the last place one would expect to find ribose? It is so difficult to imagine it forming
by chance, in fact, that Steven Benner (11/05/2004) had to envision it forming
in a desert in the presence of borate. (Not Borat, mind you no humans allowed, no matter how
perverse. Its borate.)
Now, since Benners surface model falsifies Russells deep-sea
model, and vice versa (Russell thinks the surface environment is disastrous for life),
this one little problem we raised is enough
to gum up the software and send their little computer instantly into BSOD (blue screen of death,
pun intended). We would continue with more real-world pressure, but as Windows users know,
one BSOD is enough to ruin your whole day.

intact and complete than previous specimens. Two surprises were noted; the amount
of sexual dimorphism (differences between male and female) was more than expected, and
the brain size was smaller than expected.
This specimen, in fact, seems more un-human than before.
Despite the surprises, several news reports about this fossil are noteworthy for their degree of
certainty that this particular ape belongs in the human family tree.
The surprises have not cast any doubt on the human-ancestry interpretation.
The headline on EurekAlert
was perhaps the mildest, focusing at least some attention on the problems: Brain, size and gender
surprises in latest fossil tying humans, apes and monkeys.
National
Geographic was brash: Human Ancestor had Lime-Size Brain.
Ditto for Live Science:
Human Ancestor Had a Pea Brain.
In these articles, one can look in vain for doubt that we descended from
these extinct lemurs. Jeanna Brynner wrote flatly in Live Science,
The skull belonged to a common ancestor of humans, monkeys and apes.
National Geographics scrambled lineage confuses who begat whom: apes, humans, and monkeys.
How could the discovery of such a tiny brain be used as support for an evolutionary link to humans?
National Geographic explained,
The skullof a species related to apes, humans, and monkeysis evidence that the more
advanced and bigger brains of African primates developed later than previously believed, researchers said.
You see how they do it, dont you? Evolution is
never subject to any doubt. Evolution is a fact. This IS a human ancestor, got that?
Dont even THINK of anything else. Now that you are sufficiently brainwashed to
follow the tale, uncooperative evidence can be molded to fit. They just rearrange the plot a little:
large brain size evolved a little later in the sequence that led to us. Never would it enter their
pointy-headed pea-brains that this extinct monkey, designated Human Ancestor by the Darwin Party, might be irrelevant to
the family line of Beethoven and Einstein.
True to form, the news lemmings followed the
script precisely (10/11/2006 commentary):
(1) assume evolution, (2) observe a fact, (3) make up a story to fit the fact into the assumption.
The Darwin Party is so skilled at this fability (01/16/2007
commentary), we need to coin another new word, fogma, to describe it. Fogma is dogma so thick
you cant see through it unless youre outside it. Once surrounded by fogma, it begins to represent all of realitya
shifting, shapeless mass of evolutionary change. The only thing providing a sense of
stability in all the fability is the voice of the Darwin Party announcer speaking through the fogma and
interpreting the ever-shifting view. (It is not politically correct to ask the announcer how he
knows this.)
The Charlie and Tinker Bell Theater uses state-of-the-art fogma machines with Charlies secret
recipe. It produces the perfect colloid of mythoids (05/29/2003
commentary). The stage hands aim the fogma so that it reveals only the
things they want the audience to see
the props that fit the script at the right time and conceals everything else. Surprises
are inserted occasionally to keep the audience awake. After all, every good work of fiction needs a
crisis. But not to worry; the entire production crew
knows how to bring the plot to a proper denouement.
This works well indoors under controlled conditions. Take the fogma out into the
real world, though, and the sunlight of evidence quickly dissipates it. The design of the world
then stands out in clear relief.

Seeds Muscle Their Way into the Soil 05/11/2007

A biological motor has been found, of all places, on the seeds of wild wheat.
A team of German and Israeli scientists watched wheat seeds and found they could dig themselves
into the ground. How can a dry seed, with no muscles, nerves or circulatory system,
accomplish such a feat? It all becomes clear when you look under the awning.
Youve probably seen the long strands attached to the seeds of grasses like
wheat and oats. These are called awns. Theyre not just decorative; they are
actively involved in seed dispersal. Once the seed drops to the ground, with awns still
attached, a remarkable mechanism goes into action. As the humidity rises and falls throughout
the day and night, the awns respond by bending or twisting.
How does the bending take place? At first, it seemed surprising anything
would happen, because the tissues in cross section look uniform under an electron microscope.
The authors, though, found a
remarkable feature: a huge acoustic impedance contrast in cross section that affects the stiffness
of the awn shaft from one side to the other. In cross section, the shaft resembles the shape of
a mushroom with a cap. The cap portion had twice the Youngs modulus as the stem
a stiffness the equivalent of spruce wood. As humidity changes, the differential stiffness causes the entire awn to
bend. By analogy, consider how a bimetal strip, like the coil in a thermostat,
bends and straightens in response to temperature. Not only that, silica tiles stiffen the
epidermis and protect the structure as it interacts with the soil.
So lets follow the action in the wild. The seed, awns and all, falls to
the ground. In real time, it might look like nothing
is happening. The seed, after all, is dead; its tissues are removed from any source of nourishment or internal energy.
A time lapse movie, however, shows the seed appearing to spring back to life. This time,
its a robotic life exacting its energy from the air. The
alternate bending and unbending of the awns gives a kind of muscle
to the seed, propelling it along the ground and even into the soil!
This mechanism for seed dispersal has been known for some time. Whats new
is that the scientists found tiny silicified hairs on the outside of the awns that act like a ratchet
they force the motion to go one way. As a result, when oriented horizontally, the
seed will swim like a frog along the ground. (They actually said this:
The movement is reversible; thus, the humidity cycle causes a periodic movement of the awns,
which resembles the swimming stroke of frog legs.) When oriented vertically, the
seed acts like a power shovel. The awns open and close like the handles of a post hole
digger. Meanwhile, those silicified hairs latch onto the soil particles, only allowing the seed to go down,
not up. Thus, the seed works its way deeper and deeper into the soil safely out of the reach of
predators, fire and drought. This suggests that the dead tissue is analogous to a
motor, they said. Fueled by the daily humidity cycle, the awns induce the
motility required for seed dispersal.
This mechanism is optimized, they said, for the soil environment of the Fertile Crescent,
where civilization first began to farm wheat thousands of years ago.
In some kinds of domesticated wheat, the awns are no longer active. The authors
speculated that the length of time since domestication has reduced the function of the awns without
removing them entirely. Because humans now provide the muscle to plow the seeds into the soil,
the awns have atrophied.
Apparently use it or lose it applies to seed muscle as well as the animal kind.
In their summary, the authors suggested that humans might gain additional nourishment from wheat
food for thought, that is. The passive-muscle mechanism in wheat seeds might inspire, among other things,
new ways to move weed killers where needed:
The understanding of this seed dispersal mechanism may help in developing new concepts in weed
control. The microscopic mechanism found to provide motility to the seed may
also serve as a model in biomimetic materials research. Indeed, a hydration-dependent
bending movement was recently reported in an artificial system consisting of nano-silicon columns
embedded in a hydrogel film. From a mechanistic point of view, we have discovered a
device for movement that is composed of passive elements. Locomotion is provided by
a volume containing nonoriented cellulose crystallites that shortens on drying and pulls
the awn like a muscle. The energy source for this active movement is the
daily cycle of air humidity.
Maybe someday artificial muscles in robotic devices will work without batteries, extracting the energy
they need from the environment all inspired by the slender filaments on the grass at your feet.

A passive muscle driven by moisture in the airamazing.
Could a lowly grass figure out that it needed both a tissue differential with the right acoustic
impedance to produce bending at the correct Youngs modulus, at the same time that it needed
silicified hairs to act as a ratchet? Without both, this frog would swim in place
and get nowhere. And what contractor laid the silica tiles? Silicon is not a normal
part of plant tissue; it had to be guided into place by epidermal cells while the seed was growing.
The fibrils in the awns, also, need to be arranged exactly right to produce the differential
impedance. The arrangement of all the parts needs
to be complete before the mechanism will work. Think of that then think about the additional
wonder that there are more motors, ratchets and machines at work, on a much smaller scale, inside every cell of the plant.
It was nice of the authors to spare us any evolutionary just-so stories about how this all came together
by chance. Their only use of the E word was in reference to human history: The short evolutionary
time since domestication (about 10,000 years), probably allowed the complete loss of awns in several
domesticated wheat lines, but not the alteration of the awn structure. If so, this is a case of
devolution, not evolution. They actually used the word design twice.*
Anyone believing evolution could design this mechanism needs to eat more whole wheat to provide better nourishment
to the brain.
The authors provided a couple of short time-lapse video clips to illustrate the bending action,
but the best way to see this is to get a copy of the wonderful Moody Video production called
Journey of Life. The filmmakers made an eye-popping time-lapse sequence
of wild oat seeds, which propel themselves by a similar mechanism, but with twisting action instead of bending.
You would swear you were looking at insects crawling along the ground instead of plant seeds.
This and many other ingenious seed-dispersal mechanisms are wonderfully illustrated in this film
(also recapped in Part 1 of the trilogy
Wonders of Gods Creation).**
Plants may seem passive, anchored
to the ground. In their own ways, though, they get around like world travelers: crawling, climbing, boating, ballooning,
launching, helicoptering, hitchhiking and hunting (e.g., Venus flytrap), surprising us each time with their built-in ingenuity.
*Anecdote: One of the authors of the paper works for the Biotechnology Department of the Tel Hai Academic
College in Upper Galilee, Israel. This is in the vicinity where a certain Teacher told some
parables about wheat and sowing (e.g.,
Matthew 13).
He also said, I tell you the truth, unless a kernel of
wheat falls to the ground and dies, it remains only a single seed. But if it dies, it produces many seeds.
(John 12:24).
He was speaking in reference to the results His impending death would accomplish.
**Project: This article and the Moody films suggest a science project for your junior-high or high-school
student. Many video camcorders have a time-lapse function (sometimes called interval timer).
If you already own one, you have the most expensive part of a good science project. Look for backyard weeds
and grasses with awns or other external structures; for instance, the seeds of filaree (Erodium cicurarium)
work like little power drills. Suggest a hypothesis
for how the shape of the seed contributes to its dispersal. Build a terrarium where you can
control the cycles of temperature and humidity using electrical timers, and use the camcorder interval timer to
record the action. Show your video clips with your display at the science fair. This seems like
a sure way to attract the attention of the judges and the envy of the other students.
Better still, a demonstration of biological design might kindle some thoughts about a Designer.

Stupid Evolution Quote of the Week: Design without
a Designer 05/10/2007

Apparently Francisco Ayala (UC Irvine) thinks that just stating something dogmatically is enough to
end all discussion. The scope of his paper in PNAS is grandiose and sweeping,
enough to keep philosophers and theologians from around the world busy for years, but
Ayala just put out his opinions without any hint of dispute, and stamped it with the
seal of the National Academy of Sciences. Here is the abstract from his paper,
Darwins greatest discovery: Design without a designer
Darwins greatest contribution to science is that he completed the Copernican
Revolution by drawing out for biology the notion of nature as a system of matter in motion
governed by natural laws. With Darwins discovery of natural selection, the
origin and adaptations of organisms were brought into the realm of science. The
adaptive features of organisms could now be explained, like the phenomena of the inanimate world,
as the result of natural processes, without recourse to an Intelligent Designer. The
Copernican and the Darwinian Revolutions may be seen as the two stages of the one Scientific
Revolution. They jointly ushered in the beginning of science in the modern sense
of the word: explanation through natural laws. Darwins theory of natural selection
accounts for the design of organisms, and for their wondrous diversity,
as the result of natural processes, the gradual accumulation of spontaneously arisen variations
(mutations) sorted out by natural selection. Which characteristics will be selected depends on
which variations happen to be present at a given time in a given place. This in turn depends on
the random process of mutation as well as on the previous history of the organisms.
Mutation and selection have jointly driven the marvelous process that, starting from microscopic
organisms, has yielded orchids, birds, and humans. The theory of evolution conveys
chance and necessity, randomness and determinism, jointly enmeshed in the stuff of life.
This was Darwins fundamental discovery, that there is a process that is creative,
although not conscious.
There is hardly a line in this paragraph that is not disputed by some of the greatest minds of this
and past ages, yet Ayala stated it all as a fact of science and a discovery of Charles Darwin.
The paper mostly summarized the history of mechanistic science and construed
the Darwinian Revolution as supplanting natural theology. Ignoring the
Cambrian explosion, he judiciously began his tale of gradualism after the sudden appearance of all the animal phyla:
Several hundred million generations separate modern animals from the early animals of the Cambrian
geological period (542 million years ago).... we can readily understand that the accumulation of
millions of small, functionally advantageous changes could yield
remarkably complex and adaptive organs, such as the eye, he said.
He also attributed mental and moral qualities aesthetics, rationality and even free will
to matter in motion: organisms that populate the Earth, including humans who think and
love, endowed with free will and creative powers, and able to
analyze the process of evolution itself that brought them into
existence, he said, not blinking a philosophical eye.
This is Darwins fundamental discovery, that there is a
process that is creative although not conscious. He did not ask whether a product of
unconsciousness could determine the presence or absence of consciousness in another, nor
how a product of irrational forces could rationally defend the truth of such a claim.
Apparently this was all intuitively obvious and needed no defense:
And this is the
conceptual revolution that Darwin completed: the idea that the
design of living organisms can be accounted for as the result of
natural processes governed by n |
