When Animals Crawled Ashore, There Was Nothing to Eat 04/30/2002
Fossil arthropod trackways in Canadian sandstone, reported in the
May issue of Geology,
predate the first land plants, claims a team of geologists.
These trackways put the land invasion 40 million years earlier than
previously supposed. Cross-bedding and ripple marks lead the
team to believe the rock came from sand dunes, possibly near a
seashore. The tracks were made by what appears to be
16- to 22-legged lobster-sized centipede-like animals that dragged
their tails in between their footprints.
Nature Science
Update claims this find overturns the idea that animals first emerged
from the sea to eat leafy plants, but cautions that more examples need
to be found before rewriting the natural-history books.
If there was nothing to eat, why didnt
they just go back to the water and evolve into something else? The
alternate speculation is that they came ashore to lay eggs or escape
predators. Add your story to the contest, because nobody was there,
and the dating is all based on evolutionary assumptions; sandstone is
notoriously difficult to date, a paleontologist in the
Nature news article warns. The fact that trackways were
preserved in stone indicates unusual circumstances for their preservation,
or else the next gust of wind would erase them within minutes.
Consider the plausibility of each one of their
theories: (1) If they came up to eat plants (but there werent any,
according to this story), how did their feet evolve simultaneously with
the ability to digest a new food source
and breathe air? (2) If they came up to escape predators, how
did they keep from drying out and suffocating before having to go
right back out to the danger zone? And why would they want to colonize
the land if there was no food? (3) If they came up to lay eggs,
how did all the multiple miracles evolve simultaneously to allow them to
dig and lay eggs that would not desiccate in the new environment?
And how would the young know where to go to get back to the water?
More questions arise. How did delicate trackways get preserved
in stone? How do we know the age of these rocks? Why is
there no other evidence of land animals for 40 million years?
How do they know 40 million years, or any of the other dates,
without reference to any evolutionary assumptions?
Whatever these creatures were, and whenever they lived,
they already knew how to crawl and take care of themselves.
They did not evolve upwards; they died out. That is the science;
anything else is pure fiction. Evolutionists keep finding things
that dont fit comfortably into their theory, but they never
call the theory into question; they just stretch it, like silly putty,
to encompass the new data. But if you stretch silly putty too
fast and too far, it breaks.

Evolution of an Enzyme Explained by Lateral Gene Transfer 04/29/2002
In the
April 30
issue of Current Biology,
a team of Canadian scientists claims to have found a relationship in
an enzyme (ATP Sulfurylase) between archaea, bacteria and eukaryotes.
They propose that lateral gene
transfer (LGT) is the mechanism that spread this capability from one
group to the other, and may be more important than mutation during
redundancy (MDR) as a mechanism of evolution. If so, this puts
a new twist on protein evolution: As with the MDR model, it will
be important to determine how functionally identical duplicates can
escape from frequent silencing mutations until one of the duplicates
acquires rare advantageous mutations. In any case ...
the prevalence of LGT among prokaryotes and the quantum
leaps over sequence space it permits (in contrast to point mutation)
suggests it could play a more important role in the evolution of gene
function than previously recognized.
With the title Origin and Evolution
of the Large Subunit of ATP Sulfurylase in Eubacteria, we thought
someone was finally going to try to explain how a molecular machine
evolved, but all we got was glittering
generalities and hand-waving. How can lateral gene transfer
be a mechanism for evolution of an enzyme?
It means the information already existed in another organism; it did not
originate de novo. You did not invent the monkey wrench if
you borrowed it from your neighbor. Lateral gene transfer fits into
both creation and evolution models, but has nothing to do with the
origin of new capabilities. So despite the bluffing title, these
scientists have contributed little or nothing to evolutionary theory
other than to suggest a new storytelling plot. Their little admission
in the second to last sentence, though, destroys all hope:
it will be important to determine how functionally identical
duplicates can escape from frequent silencing
mutations until one of the duplicates acquires rare advantageous
mutations. (emphasis added). Whoops!
How long do we have to wait for one of those?
Has there ever been one case of an unambiguously advantageous
mutation?
Arguably not.
Would you buy a used car from an
Afghani salesman during a bombing raid, who borrowed an engine from another
model, and said it will run better when the right piece of shrapnel
hits it? Yet this is evolutions bottom-line mechanism:
mistakes and accidents! Get real; go to the

Was the Creator a Beetle Fan? 04/26/2002
The evolutionist J.B.S. Haldane is reported to have quipped that the
Creator seemed to
have had an inordinate fondness for beetles, in light of the
remarkable diversity of Coleoptera species.
In the May
7 Biological Proceedings of the Royal Society, Peter Mayhew
of the University of New York counts the insect subgroups to quantify
Haldanes jest. he finds that beetles are not necessarily
more diverse than their sister groups, although they appear to have radiated
rapidly after evolving plant-eating habits.
Mayhew also speculates about the reasons for species diversification:
the development of wing flexion, plant eating, metamorphosis, etc.
He feels more study is needed to resolve conflicts in group ages and family
histories before species diversity among the insects can be understood.
Evolutionists like Carl Sagan have used
Haldanes comment as a jab at creationists; why would a Creator make
so many beetles, if His chief creation was man, in other words.
This biologist has shown that the number of beetle species is not way out
of line with the diversity in other groups. Thus he blunts the
force of Haldanes jab.
But what of it? There is
tremendous diversity in almost every group: orchids, fungi, birds,
dinosaurs. Picking out beetles as the object of the Creators
fondness is a selective evidence
tactic. In the Genesis view, some diversification occurred after creation
within the original kinds, but even if it was minimal, a Creator big enough
to speak quintillions of stars into existence could easily make a few
hundred thousand beetles if He wanted to. We dont know how
many were original; maybe beetle diversity should be seen as a function
of habitats that needed to be filled, rather than a statement of what was
the focus of the Creators fondness. The point is, Gods
love is not necessarily tied to the group with the most species; to claim
otherwise is to commit a non-sequitur.
Mayhews work is another example of scientific papers
that assume evolution as a glittering
generality that fixes all unknowns. Throughout the article,
complex characters like articulated legs, flexible wings, ovipositors etc.
are just assumed to have evolved somehow, and
when they appeared, as if by magic, species radiation and diversification
followed. But each of these organs is a giant structural/functional
leap that would have required the coordination of multiple miraculous
mutations just consider
all the steps involved in metamorphosis, for instance. If evolutionists
are still trying to figure out the variation in finch
beaks, how can they so glibly attribute the origin of flexible wings
(and all the associated marvels muscles, energy conversion, brain
navigation, circulatory/respiratory system changes, genetic information, etc.)
to a processnatural
selectionthat appears so inept at adding just 4% to beak length?
And where is the evidence they did evolve? Every time a
fossil insect is found in amber, scientists
marvel at how modern it looks, with its
wings and all its other complex parts
fully formed.
In his conclusion, the author laments the conflicts between
evolutionary (just-so) stories about taxon ages and phylogenies.
He recommends, as usual, that more study is required. At some point,
we need to quit the stalling tactic of sending Darwinism back to committee,
and vote whether it is a bad bill.

Eternal Universe Is Back 04/26/2002
Unhappy with the big bang with its definite beginning to time and

branes splat against each other forming universes indefinitely.
The April
26 Science, quotes Neil Turok of Cambridge, one of the
authors of the theory, as saying: It seems like a consistent
philosophical framework. Time is infinite, space is infinite, and
they have always been here. Its exactly what the
steady-state-universe people wanted. Our model really realizes
their goal.
Nature
Science Update, however, quotes many cosmologists who are
skeptical of the new idea.
Until they start with absolutely nothing,
theyre cheating. And a cosmology that disallows observation
by definition is not science, it is philosophical hand-waving.
Dr. Robert Jastrow in his book God and the Astronomers
made it clear that cosmologists have been very uncomfortable with the idea of a
beginning to the universe, because of its theological implications.
This new cyclic model is another attempt to get back to an eternally

Darwins Finches Not a Simple Evolution Story 04/26/2002
The April
26 issue of Science has a report on 30 years of study of
the birds that are one of the beacons
of evolution: the finches on the Galápagos Islands that show
variations in coloration and beak size and shape attributed to natural
selection.  Carl Zimmer comments on the 30-year study by Peter
and Rosemary Grant:
Evolution has proven predictable in the short term but unpredictable
over the course of decades, they report. Climate change has been
a powerful influence guiding the evolution of the finchesand its
effects turn out to be surprisingly complex. Natural selection is
not the only force altering the birds: So is their promiscuous sex
life. The two species on Daphne Major can and sometimes do
interbreed, and their hybridsfar from being mulelike reproductive
dead endsare a source of fresh genetic variability.
Interbreeding may be one of the secrets to the fast evolution of
Darwins finches, the Grants suggest, adding that hybrids may be
an unrecognized factor in the evolution of many other animals.
Specifically, cactus finches have been getting blunter beaks, even
though the selection pressure of the food source diminished, because
of interbreeding with ground finches. Also, the Grants watched
beaks grow 4% during a prolonged drought, but shrink back 2.5% when
the rains returned.
Look at this situation, the classic textbook
illustration of natural selection that is supposed to give us giraffe
necks and bat sonar and spider webs and monarch butterflies over time.
All the Grants have observed is a tiny 4% change, that reverted
almost all the way back when the rains returned. And the fact
that the birds can interbreed and produce fertile offspring means that
these are not really distinct species that have evolved apart, let alone
evolved into something new. Most important, there has been no
gain in genetic information. Any observed changes merely oscillated
back and forth depending on climate and food availability.
Wheres the evolution? The birds are still finches,
the beaks are still beaks, and the short-term changes do not translate
into any long-term trend.
The Grants tout their 30-year
study as being significantly longer and more valid than most evolution
research, but 30 years compared to a million is nothing. If
subtle changes could be missed in ten years, scrambling and confusing
the simplistic conclusions of Darwin, what other subtle and
unpredictable changes might be missed in a hundred, or a thousand?
How do they know that all changes they observed would not be totally reversed
in that time? Is there any validity
to the observations at all?
If this is one of the best showcase examples Darwinists can come up with,
evolutionary theory is in serious trouble. Yet the article glibly waltzes
by these problems and speculates out of thin air, hybrids ...
are a source of fresh genetic variability.
... As evolution unfolds on Daphne Major, the Grants and
their students will be watching. I.e., a disproof of
classic Darwinism may explain evolution even better! Lets have
Science explain how finches and beaks got there in the first place,
not how existing traits got shuffled around.
This article, despite its positive spin,
can be viewed as support for Jonathan Wells critical book
Icons of Evolution.
Wells debunked
Darwins finches, and nine other classic examples
of evolution, as providing any meaningful evidence
for natural selections ability to evolve amoebas into man.

Earliest Mammal Found 04/25/2002
The oldest known eutherian mammal was a mouse-sized shrew that apparently

climber) in Chinas fossil treasure trove Liaoning province gave occasion
for Nature Science
Update to surmise that it might have scampered up a tree when
a feathered dinosaur ran past. Its discoverers date it at 125
million years old, 50 million years older than the previous record holder.
The original paper is in the

They found a well-adapted little furry
animal. All the rest is storytelling. Problems: (1) The first
placental mammals must have existed even earlier (too early for comfort);
every time you move one lineage back, it pushes against the others.
(2) Why the 50-million year gap in their scheme, with no other fossils?
(3) The evolution of the complex processes of placental reproduction is
just assumed, not explained, and not clearly evident in this fossil.
(4) And, as one researcher commented, reconstructing fossils lives is
a bit of a guessing game. Why not enter your guess
into the storytelling contest? Sorry, only scientists allowed, and

Hubble Infers Absolute Age of the Universe 04/24/2002
Thats what the
NASA press
release claims, based on measurements of white dwarfs in globular
cluster M4 (see
JPL News
for pictures). They estimate these stars at 12-13 billion years old,
and report that their measurement provides an independent check that
is not related to the expansion of the universe. Age estimates based
on expansion put the universe at about 14 billion years, with the first
stars forming within a billion years of the big bang.
New
Scientist explains that the white dwarf age of 13 billion is based on
a process theoreticians understand well. Early age estimates
from the expansion of the universe were as low as nine billion, but the
recent claim of dark energy that accelerates the expansion
puts that estimate up to 14 billion. This reassures cosmologists
that stars need not be older than the universe they inhabit.
They measured brightness of these
white dwarfs for 67 days, and calculate 12 billion years: thats
like measuring one inch in a dense fog and estimating the line continues
for 1.1 million miles. The estimate is based entirely on stellar
evolution theory, which is not without problems. Actually, having
stars that old, and that soon after the big bang, underscores a major
difficulty of modern cosmology, the
lumpiness problem. What we have
here are two estimates (based on unverifiable assumptions) that did not agree,
but were tweaked into agreement so that astronomers could smile for the
press.

How Did Complex Translation Machinery Evolve? 04/24/2002
In Evolution of RNA polymerase II C-terminal domain,
two North Carolina biochemists writing in the
April 23
Proceedings of the National Academy of Scientists investigate
the cells chief translator. Portions of RNA polymerase II are
highly conserved (unevolved) in most complex eukaryotes,
particularly parts of the C-terminal domain (CTD). Surprisingly,
a pair of tandem repeats in most higher organisms is not present in
some amoebas, red algae and trypanosomes. They weigh various
theories for how these repeats arose and what their purpose is (perhaps
gene regulation), but leave many questions unanswered. The authors
conclude, these analyses suggest that the enhanced control over
RNA polymerase II transcription conveyed by acquired CTD/protein
interactions was an important step in the evolution of intricate
patterns of gene expression that are a hallmark of large,
developmentally complex eukaryotic organisms.
If you thought you were going to read
a paper on how this large, complex translation machine evolved, you
would be disappointed. The authors merely assume it
evolved, and attempt to place various organisms into an evolutionary
tree where they dont fit very well. This is typical of
evolutionary scientific literature that already knows
evolution is a fact never in their wildest dreams
would they entertain notions that grizzly bears did not evolve from
primordial soup. So they are compelled to force all data into
this prior commitment to Darwinist explanations.
A word search would turn up this paper
as an example of evolutionary scientific literature, and would provide
propaganda to a debater, but it achieves nothing of substance to
support evolution; it merely assumes it. Left unsaid is how
a highly complex translation system like RNA polymerase II could ever
have evolved without intelligent design. Here at Creation-Evolution
Headlines we are not impressed with
bluffing and
circular reasoning; we want
evidence. What is the evidence here? highly-complex,
interdependent systems that involve languages, codes, translation,
regulation, feedback, quality control and rapid-fire precision.
Lets hear papers address the origin of the most efficient
information-processing systems known on earth.
The authors actually dig their own hole deeper when
they talk about the information potential in the human genome vastly
exceeding the gene count:
The surprisingly small number of genes
found in the human genome illustrates the importance of evolutionary
advances in the control of gene expression. Developmentally complex
organisms do not appear to be distinguished so much by their total
number of genes, as by the number of ways these genes can be expressed
and controlled. Green plants and metazoans are the only eukaryotic
groups whose members are primarily multicellular and are known to have
developmental programs tightly controlled by regulated expression of homeotic genes. In addition, nuclear mRNA synthesis in animals, plants,
and fungi requires multiple protein-RNA interactions to successfully
cap, splice, polyadenylate, and cleave a completed message. What is
more, these various steps in mRNA synthesis are found to be
interdependent and are accomplished in a coordinated manner by
holoenzyme complexes consisting of the pol II core enzyme and scores of
other proteins.
As usual, Broader examinations
are needed, both of the evolutionary history of the CTD and the types
of physiological interactions that constrain its structure.
We dont understand it, but maybe more funding will help.
Adding to Darwinists headaches over intelligent
design are two other papers in the same issue: one about a
touch-sensitive
transduction channel in the bacterial cell membrane that is
exquisitely designed and effective, and another about how
non-coding
DNA sequences (so-called junk DNA) may be essential
to gene regulation.

They conclude, These findings add to the evidence that Neanderthals
used implements not only for hunting and food processing, but also in
other behavioral contexts. It is hypothesized that the high
intra-group damage potential inherent to weapons might have represented
a major factor during the evolution of hominid social behavior.

For Such a Worm (or Fruit Fly?) as I 04/22/2002
Scientists at
Penn
State Eberly College of Science think we are more closely
related to fruit flies than roundworms. They base this conclusion
on comparison of 100 genes from three completely-sequenced genomes.
This contradicts a five-year old hypothesis based on an earlier,
less-detailed study that made worms a closer ancestor, they claim.
They believe this finding can impact medicine, evolutionary biology,
astrobiology, or any other field concerned with inheritance of traits.
They argue that it is also important for textbooks to present the right family
tree, because it has an effect on how crucial events in the development
of animals are understood by future generations of scientists.
But team leader S. Blair Hedges cautions,
We could be completely wrong. I prefer to view our result
as the best supported, based on the weight of the evidence, rather than
as a proven fact. It is always better to keep an open mind about
these things, not to become married to one hypothesis or another, and
to let the data speak for themselves..
Thats great advice, if they would
follow it. They dont seem to realize the circular reasoning
embedded in their methodology. They compared slowest-evolving
and fastest-evolving genes as part of the analysis, for
instance, which of course assumes evolution rather than proving it.
This team needs to be made aware of how many
other genetic comparisons have
produced controversial and counterintuitive results. In actuality,
this team just reverted to an
old hypothesis which is sure to be championed
again by others. Hedges was surprised by the rapid abandonment
of the older, long-standing hypothesis and acceptance of the new one,
without the intense scrutiny that is typical in science.
We would say that intense scrutiny is rare in evolutionary studies.
They accept evolution as a given, without ever considering alternatives.
The result is conflicting stories about the unobservable past that merely
assume evolution rather than prove it. Which of these dubious
tales should be put into the textbooks, to influence future generations
of scientists? To let the data speak for themselves
requires the courage to doubt ones presuppositions.

Creation Research In Action: Evidence for Catastrophism Mounting 04/19/2002

Cell Water Channels Continue to Amaze 04/18/2002
If you enjoyed our December 20 story
about aquaporins, the water gates of the cell, youll want to
read this update posted by the
University
of Illinois with a cool animation of how the complex channel (made
up of more than 100,000 atoms) allows a water molecule through in a
billionth of a second, but keeps smaller protons out. Summarizing
their paper in the
April
19 Science, they explain:
Aquaporins, a class of proteins, form transmembrane channels found in
cell walls. Plants have 35 different proteins of this type.
Mammals, including humans, have 10, with many of them in the kidney,
brain and lens of the eye.
When working correctly, said Klaus Schulten, the
Swanlund Professor of Physics at the UI, the transport of water between
plant cells lets flowers bloom and leaves stand sturdily, for
example. In mammals, the machinery processes water efficiently to
help maintain optimum health.
They go on to describe the problems that broken channels can cause:
diabetes, cataracts, and breakdown of other organs. The kidneys
process 400 liters of water a day through these channels. A single
aquaporin can process a billion water molecules per second without letting
a single interloper through.
The study of channels in cell membranes
is proving to be one of the most remarkable new discoveries about
the cell. More awe-inspiring design is sure to follow.

to rectify molecular evidence (that puts the divergence as far back
as 90 million years), and a scrappy fossil record that
represents maybe 5% of the primate species thought to have existed.
Trying to reconstruct the primate family tree from fossils has been like
trying to reconstruct a 1,000-piece jigsaw puzzle using just 50
pieces, according to Robert D. Martin of the Chicago Field Museum,
co-author of the study. This new statistical estimate, while
moving molecular and fossil evidence closer together, raises new questions,
such as why more primate fossils have not been found, and why humans
evolved so late.
If you have ever worked a Rubiks cube,
you know how frustrating it is to have to undo prior successes to get colors
to match. A similar frustration happens when evolutionists
try to reconcile their molecular story with their fossil story.
The cube is being tossed back and forth between the molecular biologists
and paleontologists, who disagree with each others solutions, and
now mathematicians are getting involved.
What if their cube has no solution of the type they expect? Or
to use their puzzle analogy, what if their mental concept of the finished
picture is radically different than the actual one?
To an observer willing to question the conventional wisdom,
it is easy to find overlapping error bars that allow an infinite set of
curves to fit the data. The authors admit, While our results
agree broadly with a molecular estimate of the time of the strepsirrhine
and haplorhine divergence, they contradict widely accepted
palaeontological estimates.
Scientific American speculates about the missing fossils:
As to why such ancient primates have not turned up in the fossil
record, it may be that their remains simply did not have the conditions
necessary for preservation. One would think more time would provide
more opportunities for fossilization.
Evolutionists throw millions of years around
with reckless abandon. Scientific American, for
example, quips, Conventional wisdom
holds that primates arose no earlier than 65 million years ago
(after the demise of the dinosaurs), a date based on the oldest accepted
fossil representatives of the group, which hail from roughly 55 million
years ago, plus a few million years thrown in for good measure. But pulling on that thread unravels another yarn at the other end.
They attempt to put a hopeful spin on
the story that it might help human evolution get its conflicts resolved,
a hopeless shambles as Science
reported February 15. Of course, any story is possible; this new
scenario is written in
if-then-else, but-maybe, and on-the-one-hand on-the-other language, with
both hands waving in an evolutionary fog.
It attempts to explain away missing evidence and fill in gaps between
what should be and what is. Shouldnt science be about what
is found, not what is not found?

New Insect Order: Relative or Puzzle? 04/18/2002
Nature Science
Update reports that a weird insect, something between a walking
stick and a praying mantis, has been found enclosed in amber in the
mountains of Namibia. Entomologists are classifying it into a
new insect order, the first such new insect category since 1914. Is it a
transitional form? Michael Whiting
of BYU is sequencing its DNA to see if it shows an evolutionary relationship,
but cautions against expecting cut-and-dried answers: Weve
known about the other orders for centuries, and we still havent
worked out their relationships. This is one more piece of a large
and complex puzzle: its exciting to have the piece, but its
not going to provide the answer by itself. Others describe this
find as a living fossil, comparable to finding the fish
Coelacanth. The original paper in
Science
says the morphological evidence [of relationship to icecrawlers or
walking sticks] is ambiguous. See also this report by the
Max Planck Society for
the story of the discovery, with pictures.
Whiting is right not to expect to see
evolution in the DNA. We have shown
repeatedly that the ancestry story
in the genes rarely matches the ancestry story inferred from bones.
Maybe the ancestry story is a novel, not a documentary.

Biology Viewed as Computing 04/18/2002
In an essay in the
April 18 Nature,
Mark Schnitzer, a member of a Bell Labs department of Biological
Computation, portrays an organism as just a user of
the hardware and software of the cell. This contrasts with
the mechanistic view of life as an aggregate of simple components;
according to Schnitzer, algorithms must be taken into consideration:
In the algorithmic view, complex algorithms cannot be
deduced from simple mechanisms as there are emergent computational
principles that cannot be found by combining biophysical
components. By analogy, the mathematics involved in rendering
three-dimensional graphics on a computer do not follow from the
workings of transistors. Hence, we should study the
representations and algorithms used by systems that exhibit rich
computational behaviour.
Schnitzer credits the software engineering to evolution:
A shared evolutionary history has often given rise
to similar molecular and genetic mechanisms across a wide range of
organisms....
Schnitzer comes very close to accepting
the Intelligent Design premise that information is a fundamental
entity that must be considered in evaluating complex biological systems,
but he mistakenly believes that natural selection, that magic wand of
evolution, is capable of generating it. The only cause we know
that can generate algorithms is intelligence. Bill Gates does not
employ random number generators to write his software (well, to some
it might seem so, but thats beside the point). Unguided,
purposeless processes are inadequate to generate the most elaborately
detailed assemblage of information in the known universe: the DNA code,
with its associated storage, translation, processing and manufacturing
subsystems. We agree that an algorithmic view is
the only sensible way to evaluate biological systems; that phrase can be
considered almost synonymous with Intelligent Design

Spiders Beat Humans in Materials Engineering 04/16/2002
Another paper on spider silk in the
April 16 online
preprints of the Proceedings of the National Academy of Sciences
praises the lowly spiders materials science:
The last decade has seen a significant increase in the scientific
literature on spider dragline silk. This interest is due to the
impressive mechanical properties of spider dragline silk, at a time
when biomaterials and biomimetics are both exciting interest in the
rapidly growing field of materials research. The viscoelastic
fibers of spider dragline silk combine both a high tensile strength
that is comparable to steel and is only slightly inferior to Kevlar
(2/3 of its tensile strength), and a high elasticity (30% elongation
before failure) that is comparable to rubber. This unique
combination makes spider dragline silk mechanically superior to almost
any other natural or man-made material.
The team from UC Santa Barbara probes the unsolved structure of this
remarkable material and find the structure of spider silk protein to
be distinctively different and novel compared
to other proteins. They propose a model for how it can be both
rigid and flexible, how sacrificial bonds allow it to
stretch, and how stacked and staggered slabs of complex proteins,
made up of 38 amino acids each, interlock with hydrogen bonds
during the draw-down process.
The team tested how much force was required to unfold the neatly-folded
nanofibers, and even then, found that a catastrophic unfolding of a
single protein rarely occurred.
Update
On August 7, a UCLA
press release described how spider silk combines strength and toughness,
is resistant to degradation, and can be spun in air or underwater.
It says tiny spiders are outwitting human materials engineers
by producing this remarkable substance seemingly without effort.
What kid staring at a geometric orb-web
has the faintest clue how much structural engineering went into its
construction? How did a tiny spider figure all this out?

First Cell Not Salt-Tolerant 04/15/2002
Charles Apel of UC Santa Cruz has found that the first cell could
not have formed in salt water, so it must have formed in fresh, reports
Academic
Press and the
NASA
Astrobiology Institute.
This is a wake-up call, says mineralogist Robert Hazen of
the Carnegie Institution of Washington in Washington, D.C.
Weve assumed that life formed in the ocean, but
encapsulation in freshwater bodies on land appears more
likely. Geologist L. Paul Knauth of Arizona State
University in Tempe adds that Earths early oceans were up to
twice as salty as they are todaymaking it even more difficult for
viable cells to arise.
Astrobiologists had assumed lipid molecules would self-organize into
vesicles, but apparently salt makes them fall apart. Apels
findings were delivered at last weeks Astrobiology Conference,
and will be reported in an upcoming issue of Astrobiology Journal.
Another devastating blow to believers in chemical
evolution. Of course, every other assumption they still cling to
has already been shot down. The fresh-water requirement vastly
reduces the playground for molecules (remember how deep-sea vents were
the last hope?), but too fresh and you lack the needed ingredients.
The Miller Time party is over; its time for sober-thinking
Intelligent Design scientists to come to the head of the class.

Humans and Apes Differ in Brain More than Liver 04/12/2002
Scientists at the Max Planck Institute for Evolutionary Anthropology
compared gene expression between chimpanzees and humans in the brain
and liver, and found the most differences in the brain. They feel
this points to gene expression, rather than genome difference, as being
the most important determinant in recent human evolution.
Their results are published in the
April 12
Science. They feel that accelerated gene expression in
the brain led to our humanness, but caution that It should be
noted, however, that the extent of the acceleration is highly dependent
on the metric used.
The finding creates some controversy about the timing,
since the authors believe the gene expression accelerated recently,
but anatomical differences began much
earlier, according to the standard evolutionary timeline.
Others, however, are elated to see these differences in gene expressions
between apes and humans. In her news summary of the paper,
Elizabeth Pennisi quotes Edwin McConkey, a molecular biologist, as saying,
If no differences had been found, then we should all have to take
a course in metaphysics, and religious fundamentalists would be dancing
in the streets.
Come again? Sounds like we have found a
non-sequitur. Religious
fundamentalists feel like dancing in the streets all the time anyway,
and everyone should take a course in metaphysics, because no one reasons
without metaphysical assumptions, including
scientists.
The authors
disclaimer about the metric used means that you can pick and choose the
data that support your conclusion. It also means that comparative
gene studies have little value in constructing evolutionary family
trees, because a simple gene count or comparison wont necessarily
tell you which genes get expressed. We reported on
April 9 that the Hox gene cluster differs more between
sharks and zebrafish than between sharks and humans, so some genes
evolve very fast and others not at all, if the evolutionary time scales
are accepted. A consequence is that they are basically useless for
providing independent corroboration of ancestry.
This paper cites the oft-quoted statistic that human
and ape DNA is 98.7% identical, a doubtful measure since ape genomes
have not been completely mapped yet. But even if true, this
paper clearly shows its not the whole story. How genes are
expressed may be more indicative of differences between organisms.
Regardless, this paper shows that by selecting
the metric you can spin the story either way.
Dr. Gary Parker likes to quip that a 2% difference can mean a lot; both
clouds and watermelons are 98% water. We should also point out
that apes do not have metaphysics, nor do they dance in the streets.

Chimps Trained to Read 04/11/2002
A breakthrough in animal communication, or Stupid Pet Tricks?
Sally Boysen, a psychologist at
Ohio State,
claims she
has taught her pet chimps Keeli and Ivy to read about twelve words.
She couldnt teach them the alphabet, so she tried whole-word
recognition. The next trick is to teach them syntax and maybe
someday to tell us - in their own words - about chimpanzee culture
and society. Her work is featured on this coming Sunday
night on the
Discovery
Channel.
The power of suggestion and conditioned
response can often cloud these kinds of studies. Circus trainers
have taught horses to do arithmetic and parrots to tell jokes.
Who knows what a chimp is thinking? Is it responding to subtle
cues from the trainer in hopes of getting a banana, or does it really
understand what a word is and what it means? There is no question
that animals can be trained to do all kinds of amazing tricks; look at
sea lions and dolphins; they can even clap and laugh and pull stunts enough to
make the audience almost believe they outwitted
their trainers.
Wed like to see the controls that
prove these chimps have really learned vocabulary instead of how to act out
a conditioned response. That they could not put letters together
into words, nor words into sentences, are indications they no comprendo.
And the idea that they are going to tell us
about chimp society someday well, sounds like good grist for
the cartoonists.

Book Review 04/11/2002: In the
April 11 Nature,
theistic evolutionist John Polkinghorne, winner of the 2002 Templeton
Prize for progress in religion, takes Stephen Weinberg to task for his
reductionist philosophy in his 2001 book, Facing Up: Science and
Its Cultural Adversaries But in the end, Polkinghorne explains
the origin of evil with a God (god?) who allows the universe to evolve
itself into good and evil: an evolving world (theologically, a
creation allowed to make itself) is one in which cellular
mutations necessarily bring about not only new forms of life, but also
malignancy.
In this he essentially affirms deism,
not Christianity, because his god is either too weak or unconcerned to
create a world good from the start. Christianity teaches that the
originally good creation fell into sin and was cursed. Gods
solution for evil is not
to crush its every manifestation, else He would destroy the world, but
to provide a refuge to anyone who repents and believes His promise of
salvation, paid for by His Sons sacrifice on the cross.
It is doubtful such a compromising position with evolution as
Polkinghornes will make much of an impression on the readers
of Nature, since it makes suffering part of the intrinsic order
of things instead of an intruder; evil becomes the handiwork of the god.
Bacteria Are Champion Proofreaders 04/10/2002
A team of Australian biochemists has examined the structure of
just one of the proofreading enzymes in E. coli
bacteria in unprecedented detail, and formulated a hypothesis for
how it works. That it does work, and works extremely well,
is described in the introduction to their paper published in the
April
issue of Structure:
Fidelity of DNA replication is determined
by three processes: base selection by a DNA polymerase, editing of
polymerase errors by an associated 3'-5' exonuclease, and
postreplicative mismatch repair. In Escherichia coli,
these processes contribute to duplication of the genome by the
replicative DNA polymerase III (Pol III) holoenzyme with error
frequency ~10-10 per base pair
replicated.
In other words, with its proofreading machinery, the bacterium
makes a error once in 10 billion DNA letters.
Assuming 2000 letters on a page of single-spaced printed text, that would be
roughly equivalent to one typo in about five million pages.
This high degree of fidelity is
necessary; without it, errors would accumulate rapidly, causing
the complete breakdown of the genome in a phenomenon called error
catastrophe. How did a lowly bacterium achieve such
accuracy? The paper mentions evolution three times, but never
explains how such a system evolved; it just assumes that it
did, and notes that the equipment is highly conserved
(unchanged throughout living things).
In the new film on intelligent design,
Unlocking the Mystery of Life, Dr.
Michael Behe describes how he came to doubt Darwinian evolution.
He went through college never hearing how Darwinian evolution
could explain the cell, but just was told that it did explain
it, and assumed it to be true. When he heard some convincing scientific
arguments against Darwinism, he said he became somewhat angry, because
he felt he had been led down the primrose path he had gone through
a graduate program, obtained a doctorate in biochemistry and became a
university faculty member, and he had never heard of these things.
The arguments made him very interested in the subject of evolution,
and he since concluded that Darwinian mechanisms are not sufficient to
explain the complexity of life; they are very inadequate, in
his opinion.
High-fidelity proofreading is just one of thousands of
evidences that undirected natural processes are insufficient to produce
the wonders in living cells. That is part of what makes the case for
intelligent design so convincing to more and more scientists and science
teachers. Too bad the authors of this otherwise wonderful scientific
paper are still on the primrose path.

Sharks Closer to Humans than to Bony Fish 04/09/2002
A paper by a team of biochemists in the April 9 online preprints of the
Proceedings
of the National Academy of Sciences, Molecular evolution of
the HoxA cluster in the three major gnathostome lineages, puzzles
over why horn sharks appear closer to humans than zebrafish.
They studied the clusters of genes (Hox) responsible for body-plan
development and uncovered three unusual patterns (in addition to the fact
that horn sharks and humans have only one HoxA cluster, but zebrafish have
two):
- Bony fish do not have many homologous gene markers found in horn sharks and humans.
- Very few of the animals studied have all the markers.
- Zebrafish have some compressed subsets of markers from bony fish and
humans; these are found in non-coding sequences between genes.
The scientists puzzle over these findings, especially the fact that
clusters of two distantly related taxa, the horn shark and human,
are remarkably conserved in architecture and putatively functional
cis-regulatory sequences. Some of the zebrafish differences
they attribute to cluster duplication, but the various evolutionary
mechanisms they propose each have problems that dont match
expectations. They marvel at the similarity of horn shark and
human HoxA clusters:
Nevertheless, our results are intriguing, because despite the fact that
human and horn shark diverged from one another more than 400 million
years ago and have considerable differences in morphology, selection
acting on the HoxA clusters has been strong enough to maintain their
remarkable conservation in putatively functional cis-regulatory
sequences in the absence of a cluster duplication. Yet, after
HoxA cluster duplication in the zebrafish, radical remodeling of cis
sequences occurred even when only one gene is retained to perform these
functions. Interestingly, some of the cis elements conserved in
human and horn shark and absent in zebrafish are retained in the
striped bass and vice versa (Table 1). If modification of
cis-regulatory elements is caused only by relaxed selection, then the
homologous, ancestral cis elements in all teleost lineages should be
affected. The retention of different ancestral elements in
zebrafish and striped bass suggests that cis-regulatory elements in
elements in these different lineages have been shaped by distinct and
different selection pressures.
To interpret the unexpected findings, they propose that maybe Hox
clusters evolve differently than other clusters after they have been
duplicated.
So there you have it: no clear evolutionary
ancestry in the genes (again). These scientists would have us believe
that this HoxA gene underwent essentially no evolution for 400 million
years, while the family tree evolved through amphibians, reptiles,
mice, elephants and man, but simultaneously in all that time, the
homologous genes in zebrafish evolved extensively. So is evolution
an inexorable force, or not? It acts on different genes differently,
and at different rates, so that even when the evidence contradicts evolution,
it can be spin-doctored to support it.
Notice how these scientists
accept without question the 400-million year divergence time for
shark and human lineages. This a priori assumption forces
them into logical contortions when looking at the evidence.
Sharks closer to humans than to zebrafish; can you believe it?
Evolutionists were optimistic that DNA sequences were going to tell the
true evolutionary history of life on earth, but the genome has proven
to be like

Cheating Female Birds Do Their Fling 04/09/2002
Scientists reporting in the April 9 preprints of the
Proceedings
of the National Academy of Sciences studied collared flycatchers
for evidence of sperm competition as a means of sexual
selection. They claim to have found that the cuckolding female
times her affairs to help the sperm of the more attractive male succeed in
fertilizing the eggs. They measured a 5 to 1 advantage of the
extramarital sperm despite 1.33 affairs per female. They say,
Our results suggest a possible behavioral
mechanism for female control of sperm competition.
This paper reeks with the
personification fallacy.
They rate the size of a males forehead patch as a measure of
attractiveness, as if the female has human aesthetics.
Why didnt the girl bird marry the handsome guy to begin with?
How come there are any male flycatchers with small forehead patches left,
after millions of years of evolution?
And why dont all male birds have forehead patches?
The authors invoke the weird-science
idea of sperm competition as if single cells care about winning
some olympic event.
But then they portray the female timing her affairs so that the adulterer
succeeds (this idea feeds the feminist agenda, because it puts the woman
in charge).
But neither males nor females matter: its the genes themselves
that are selfishly using the birds (and us) as pawns in their quest for
eternal life.
Materialists are not allowed to attribute any of these
personality traits to objects, in their philosophy.
We need an umpire to call

Dying Cell Does Orderly Shutdown 04/09/2002
Cells go the way of all the earth, too, and when its time to expire,
a cell performs an orderly shutdown called programmed cell death
or apoptosis. When a factory goes out of business, somebody
needs to stick around to finish the paperwork, recycle the raw materials,
and call in the wrecking crew but in the proper order.
Similarly, cells have some final work to do in a logical sequence, and
scientists are just beginning to understand all the steps involved.
In the April 9 online preprints of the
Proceedings of
the National Academy of Sciences, Israeli biochemists have studied
just a few of the procedures. They found that not only are existing
proteins activated for the grisly job, but additional death
proteins are built before the assembly line is shut down. As
a result, the cells parts can be recycled for the next generation.
The Creator thought of everything.
To get a taste of just how complex a simple thing like dying is, consider
this excerpt, included not for your comprehension, but your wonderment:
Apoptosis induction in several cell lines
and by numerous triggers has been associated with a rapid and
substantial reduction in protein translation rate primarily because of
reduced translation initiation. This reduced translation has been
correlated with caspase-mediated activation of the dsRNA-activated
protein kinase (PKR), which inhibits initiation of protein translation
by phosphorylating eukaryotic initiation factor (eIF)2 as well as with
the caspase-mediated inactivation of several translation initiation
factors including eIF4B, eIF3/p35, eIF2, and proteins of the eIF4G
family. It was correlated also with alterations in the
phosphorylation state of eIF4E, 4E-BP1, and eIF2.
Importantly, 30% of the normal level of translation events persist, at
least in some apoptotic circumstances. It seems that the
translation rate is not inhibited in a global and uniform
fashion. Rather, the translation of a subset of mRNAs prevails in
the dying cells. These mRNAs include those of the proapoptotic
proteins death-associated protein 5 (DAP5), c-Myc, and Apaf-1 and the
antiapoptotic protein XIAP. A common feature of these mRNAs is
their translation via an alternative mode named cap-independent
translation, mediated by internal ribosome entry site (IRES) elements
in their 5' untranslated regions (UTRs). Furthermore, each of
these IRES elements suffices to maintain the translation of a reporter
gene in dying cells, whereas the cap-dependent translation mode is
abrogated severely. These IRESs are referred to in this work as
"death IRESs," because they maintain their translation rate in the
dying cell.

India Retires Pigeon Service 04/08/2002
In an underdeveloped area of east India, e-mail is replacing p-mail; after
55 years of reliable service, the states 800 carrier pigeons, and
the 40 cops who trained them, are being retired from duty.
According to the
Washington
Times, the state of Orissa began a carrier pigeon service in 1946 to
get messages through in spite of cyclones, floods and drought, when remote
areas were otherwise inaccessible. The pigeons, who can travel 50 miles
an hour, proved their worth many times.
With messages in little metal
cylinders banded to their legs, they could be counted on to reliably
fly home. In addition, describes the article, The boomerang
service, operated by better-trained recruits, offers a two-way exchange of
messages. The birds fly to a police station or an outpost, feed
from a wooden box stacked with grain, and then make the return journey
home with their message. Modern instantaneous
telecommunications has rendered the service obsolete, but many are
sentimental about the loss of the pigeon service, the only one of its
kind in the world. An official who hopes to keep a skeleton crew
operating in case of a paralyzing natural disaster, commented,
Machines will fail you, but birds never will.
Two wonders of creation are here displayed.
One is the wonder of a birds brain, that is able to reliably

Foul-Smelling Gas, Over Time, Becomes People 04/08/2002
The discovery of methane in deep crevices in mine shafts sheds
clues about the origin of life, thinks
National
Geographic: As far back as the 1880s, miners in North Canada,
South Africa, and Scandinavia have reported mysterious, foul smelling
gases that hiss and spit from crevices deep in mine shafts. Now
scientists have discovered the origin of these gases and have found
that these anomalous emissions may provide a missing link in the
evolution of life on Earth. The news article is based on
a paper in the April 4 Nature.
The paper only claims the gas in the mines
did not come from the usual biological sources (rotting carcasses, bovine
flatulence etc.). It says nothing about the origin of life.
Ever since
Stanley
Millers presumed early atmosphere of methane and ammonia has been
debunked, evolutionists have looked for a source of gases that
could produce hydrocarbons and the building blocks of life.
That phrase building blocks of life is profoundly misleading.
It glosses over the major differences between naturally-forming compounds
and information-rich DNA, between bricks and cities, between
scattered alphabet letters and books.
National Geographic does a great disservice to leap from the
discovery of foul-smelling gas to the origin of life. It not only
keeps false hopes alive; it really hurts our self-esteem, turning us
all into a bunch of old you-know-whats.

Two Unlike Proteins Do the Same Job 04/06/2002
Two unlike organisms, yeast and a protozoan, have proteins that bind
to telomeres; these proteins are required for chromosome end protection
and telomere replication. They look alike and do the same job,
but are very different in amino acid sequence, reports a paper in the
April
5 Science. The authors believe this indicates
that mechanisms of telomeric end protection are widely conserved
throughout evolution.
In another paper in the same issue,
British
biochemists have found a chromatin protein that is conserved in
archaea, bacteria, and eukaryotes (including people). The protein
Sir2, in combination with Alba, is important for repressing expression
of genes not needed at the time. They conclude that this
partnership may have been highly conserved throughout evolution.
Evolution is, again, just assumed, not
demonstrated. How two different sequences could have ended up
with the same basic shape and function only multiplies the improbability
either of them could have hit the lucky jackpot. In the second
case, you have complex systems in place in the most primitive living
things, right from the start. That is the rule, not the exception.
Remember that amino acid sequences must be very specific,
and must be
assisted to fold properly by other specifically-sequenced proteins.
Nature
said this week (April 4) that misfolding
can turn benevolent proteins into instruments of death.

Why Cancer Is Rare 04/04/2002
Anyone who has been diagnosed with cancer, or had a loved one with it,
knows what a frightening and unwelcome surprise it is. But according
to Robert Weinberg, cancer researcher at the Whitehead Institute for
Biomedical Research, the surprise is that our bodies are usually so successful
in preventing it:
There are so many things that need to go wrong, so it is not surprising
that, in a lifetime, cancer is actually rare. Most cancers are
caused by mutations, and very few cancers are caused by a single
mutation. Mutations tend to accumulate as the cancer progresses;
that is why early treatment is usually successful.
Weinbergs comment appears in a status report on cancer research
by Alison Abbott in the
April 4 Nature.
Life is so complex, and there are so
many factors (cosmic rays, chemicals, etc.) that can cause damage,
it is a wonder most people live as long and healthy as they do.
The only way that happens is for the cell to have elaborate
repair mechanisms and
quality control systems to check
for errors and fix them. If you are healthy now, enjoy it, because
sooner or later, one way or another,
God has ordained that your
earthly body will not last forever. But there is a
resurrection
body prepared for those who
put
their trust in the
risen
Messiah, Jesus Christ, that will
no
longer be subject to the ravages of disease and death. If the
earthly body is so well equipped to survive in a
world
cursed by sin, how much more amazing will be our
resurrection
body where
sin,
disease, pain and death have been removed forever?
Until then, those going through cancer or other trials can have
hope in the promises of God.

Cell Assembly Line Workers Tethered Together 04/04/2002 A paper by two Harvard biochemists in the
April 4 Nature
explores new findings that the molecular machines that perform
gene expression are all tied together (coupled) in assembly-line
fashion, so that one process hands off to the next instead of
waiting for the next machine to show up by chance:
Recent studies lead to the view that, in
contrast to a simple linear assembly line, a complex and extensively
coupled network has evolved to coordinate the activities of the gene
expression machines. The extensive coupling is consistent with a model
in which the machines are tethered to each other to form gene
expression factories that maximize the efficiency and specificity
of each step in gene expression.
In describing the elaborate processes that read and translate DNA,
the paper uses the words machine or machinery 53 times, and
factory or factories 10 times. And theres more:
Superimposed on this pathway is an RNA surveillance system
that eliminates aberrantly processed or mutant pre-mRNAs and mRNAs
i.e., a quality control subsystem.
Our modern discovery of the cell as a highly
complex factory of molecular machines (as shown so beautifully in the
film Unlocking the Mystery of Life)
should be awe-inspiring, and a cause of great fear to Darwinists.
Every week, papers like this seem to make the idea that this level of
complexity could just evolve increasingly untenable. Note that this paper
contains just a passing reference to evolution in the introduction, but it
is forced, useless, and unnecessary, as if the authors feel obliged to
offer their pinch of incense to the emperor and get it over with.
This paper has nothing to do with evolution, and everything to do with
intelligent design.
Critics of intelligent design make a big deal of the
claim that no scientific papers are written from an intelligent design perspective,
but thousands are written from an evolutionary perspective. This
argument is pure sophistry, as this and many other scientific papers
in our archives demonstrate (search on the Chain Links amazing
and Cell). Sure, a word search on this paper in Nature
will turn up the word evolved but not the words intelligent
design, but what a misleading impression it would
give! Nowhere in this paper do the authors explain how an
automated factory could evolve; they simply assume it. But then
they go on to describe almost with a sense of awe the amazing processes
of gene expression, as a system of machines in a coordinated factory,
with even quality control built it!

Sponges Hint at the Fungus Among Us 04/0
3/2002
An evolutionist thinks we came from sponges, which are similar to fungi,
therefore it would mean that the entire animal family is just a branch
on the evolutionary tree of the fungi. In a sense, peopleand all
animalswould be highly evolved fungi. Well, maybe some
people more than others. The colorful story can be found on
National Geographic.
This story is included for your
amusement. It assumes evolution through every spore, breathes it through
every pore. What hath natural selection wrought!
No hint that anyone, anytime, anywhere, believed something different.
Browse and look at the amazing claims made for evolution just on the
basis of authority.
Lets see, somewhere there was some raw data in this article; where
was it? Oh yes, there it is: Sogin extracted genetic
material called RNA from the various organisms and compared two types
of genetic data from each. The two types of RNA told slightly different
versions of the family history of the animals, but both sets of
evidence agreed on many accounts. Once deciphered, the genetic clues
revealed that, of all animals, sponges are the most genetically
distinct. Most of his findings were a surprise, and not
expected from evolutionary assumptions. Nevertheless, were
here, therefore we are highly evolved fungi.
Evolution is not a process that just stops, says
Sogin. Well, it seemed to stop for living
fossils.

Scientists Coax Molecules to Self-Assemble 04/02/2002
A hot topic in biochemistry is self-assembly, the designing of
molecules that can join into structures like tubes, lattices and helical
shapes.
Traditional chemistry dealt with atoms and molecules; the new
supramolecular chemistry deals with groups of molecules that
form larger structures by virtue of their electrical and chemical
attractions and repulsions. Biological molecules depend on supramolecular
interactions, and now scientists are trying to follow their example.
The April 2 online preprints of the
Proceedings of the National
Academy of Sciences contains several papers by chemists working in this
microscopic realm of engineering. One group got peptides to form
nanotubes and
nanovesicles, and concludes, This surfactant peptide system
also may capture the prebiotic environments simple origin and
complex outcome. Another team got
helical
shapes out of polymers.
The authors of another paper begin with these comments:
Life could not exist without motion induced by a variety of molecular
motors. The construction of artificial motors by chemical
synthesis, which can power motions that lead to macroscopic detectable
effects in a system, is a major endeavor in contemporary science. ...
Inspired by natures nanomachinery, there is great current interest in
the design of molecular systems that mimic motor functions and are
capable of performing linear or rotary movement. Among the
fascinating structures designed to induce mechanical motions are
shuttles, muscles, ratchets, pseudorotaxanes, and switches.
They reported getting two molecules in a liquid crystal film to
rotate relative to each other, forming a primitive
molecular
motor.
Although these are interesting experiments
on a cutting-edge area of chemistry, they are of no help to evolution.
- These structures carry no information. They are repetitive
structures, larger than but similar to crystals. Like a broken
record, they are ordered but not informative.
- They are very primitive compared to living molecular machines.
The motor
that one team described was made of two simple molecules rotating with
respect to each other in one direction only, with the input of
light. By contrast, ATP synthase, a biological motor, is made up of
hundreds of precisely ordered amino acids. It not only rotates,
it clamps together ATP molecules in a three-phase assembly cycle,
rotates at nearly 6000 RPM, and is reversible. The bacterial
flagellum rotates at 100,000 RPM and is also reversible; it is made up of
40 protein parts.
- Each of these structures required the
input of intelligent design by the scientists. These molecules
never would have been found together nor organized into the structures
without specific guidance by skilled, intelligent scientists.
In living cells, DNA codes for and directs the assembly of molecular
machines; they do not self-assemble. Another critical
point is that the scientists selected single-handed ingredients, which
would have been astronomically improbable in nature.
- Natural selection cannot help a self-assembling structure to
evolve or even survive. Even if a simple molecular machine formed
by chance (a wild speculation), it would be useless by itself.
Unless it were part of a cell that could reproduce all its parts, and
unless it provided some functional advantage to that cell, there would be
no natural selection. No one would care if it survived or fell
apart with the next cosmic ray.
Evolutionists are not allowed to inject intelligent guidance at any
point in their naturalistic explanations of origins, or else they shoot
themselves in the foot. Claims of self-organization and
self-assembly, therefore, need to be qualified with these essential
differences between their intelligently-designed work and the theory
of chemical evolution, before assuming such experiments provide
evidence for the plausibility of a naturalistic origin of life.

Book Review 04/02/2002: Kevin Padian in the online edition of the
March 29
issue of Science, reviews Robert Pennocks new book
Intelligent Design Creationism and Its Critics.
This review breathes fire.
It is startling to see the hatred some scientists have for creationism;
it borders on hysteria. The review is full of ad hominems, genetic
fallacy, second-guessing the agenda, loaded words, association,
and other hot-air arguments devoid of
a rational look at the evidence. Phillip Johnson, one of the evil
perpetrators of ID, keeps his cool, though; in his
Weekly
Wedge Update, he sees it as a backhanded endorsement:
everyone is talking about us, or issues related to us, and the Darwinians
are very worried. They still like to claim that they can't teach
the controversy because there is no scientific controversy to teach,
but then, what are Science and the MIT Press so absorbed
with?
Watch the film and you be the judge.

Humans Evolved Narcotics Use 04/01/2002
According to
New
Scientist, two anthropologists have a theory that humans evolved
the use of narcotics as a survival strategy. Stimulant alkaloids
like nicotine and cocaine could have been exploited by our human
ancestors to help them endure harsh environmental conditions,
says Robert Sullivan of the University of Auckland.
Note: This is not an April Fools
joke! Well, I guess we should release all the offenders in
our jails. Its not their responsibility; its
evolution; its survival of the stoned.

ABC News Reports Ohio Intelligent-Design Controversy 04/01/2002
In Charles Darwin is in the hot seat again,
Amanda
Onion of ABC News reports on the ongoing controversy over the
teaching of evolution in Ohio schools, and whether criticisms or
alternatives should be permitted to be taught.
Again, you will look in vain for
any argument of substance against teaching intelligent design.
I have great concern that we will be a worse joke than Kansas,
= ridicule. If we point out that
evolution is unproven, well need to point out that the theory of
gravity is also unproven = faulty
analogy. And evolution is a much stronger theory than
the theory of gravity = Big Lie.
Evolution is the scientific view that needs to be presented =
authority. Discovery Institute ...
is funded in part by Christian foundations =
guilt
by association.
The fact that the theorys explanation is mystical, says Behe,
is beside the point, -- they do not quote Behe here, and it is
doubtful he would have used the loaded word
mystical. (Even if he did, the point is irrelevant, since
intelligent design is about observations, not explanations).
The people pushing the agenda in Kansas learned a lot ... This
approach is more subtle than creation and, frankly, more clever =
scare tactics and hate mongering;
the fallacy of the hidden agenda. 2700 citizens sign a pro-Darwin
petition to counter the 52 scientists
who petitioned for alternatives to be heard =
bandwagon. (Notice also, this depends
on the character and knowledge of the signers, not the numbers;
a million imbeciles can outvote, but not outsmart, one Einstein).
As these excerpts show, opponents have nothing but hot air to argue that
students should be prevented from hearing
arguments against Darwinism and for intelligent design.
