Quick Picks 03/31/2004
Too many stories came in too fast at the end of March. Here are some
we would have liked to explore in more detail. Theyre all
interesting and some have amazing facts and quotes.
- DNA vs. Evolution: A paper in the
Royal Society Biology
Proceedings1 warned that pleiotropy, the antagonistic effect of
genes that need to mutate together, inhibits natural selection more than is
usually realized. Sarah P. Otto writes,
Pleiotropy is one of the most commonly observed attributes of genes.
Yet the extent and influence of pleiotropy have been underexplored in population genetics models. ...
Under the assumption that pleiotropic effects are extensive and deleterious, the fraction of alleles that are beneficial overall is severely limited by pleiotropy and rises nearly linearly with the strength of directional selection on the focal trait. Over a broad class of distribution of pleiotropic effects, the mean selective effect of those alleles that are beneficial overall is halved, on average, by pleiotropy.
(Emphasis added in all quotes.)
Thus the simplistic notion that a beneficial mutation will be acted on by natural selection
is severely limited by the effect of pleiotropy.
- Starbirth: In an article in the 19 March issue of
Science.2
Robert Irion puzzles over why recent surveys of the heavens seem to indicate
star formation was rapid in the early universe yet so slow today:
As findings from these surveys cascade into the literature, they are shaking up notions about the evolution of star birth in the young cosmos. Observers have found that some galaxies matured quickly after the big bang and then flamed out, forming giant blobs of stars that may have barely changed in at least 10 billion years. Another population of galaxies kept evolving [sic], churning out new stars for eons and gradually settling into mature but mildly fertile galaxies such as our Milky Way.
But these claims seem to belie the uncertainty in the minds of modelers.
The following admissions of ignorance are startling, considering the ease with which the
textbooks present the story of starbirth and galaxy evolution:
Current theories of galaxy formation cant explain why concussive waves of star birth swept through some early galaxies but not others--and why some of those fierce stellar fires got snuffed after a few billion years [sic]. Startled by their own data, a few observers have implied that modelers of the cosmos need new ideas to describe our universe's combustive childhood (Science, 23 January, p. 460).
Theorists arent yet ready to revise equations on their cluttered whiteboards, but they agree that the surveys illuminate serious flaws. Were starting from a shaky foundation, says cosmologist Carlos Frenk of the University of Durham, U.K. We dont understand how a single star forms, yet we want to understand how 10 billion stars form. Fellow theorist Simon White of the Max Planck Institute for Astrophysics in Garching, Germany,
concurs: The simple recipes in published models do not reproduce the star formation we see. Theorists are now having to grow up.
Irion doesnt contradict the predicament; he just hopes that new sky surveys will clear up the mess.
- Alfred Russell Wallace: Nigel Williams reviews Michael Shermers
bio of the man who independently discovered the law of
natural selection.
Wallace was a colorful but tragic character. He went on some legendary
adventures in Malaysia and elsewhere, and graciously played second
fiddle to Charlie, but was also suckered by spiritualism and the fallacies
of his own beliefs. He was another victim of loss of faith in the
credibility of the Bible during his youth. Janet Browne, in
Charles Darwin: The Power of Place (Princeton, 2002) has many interesting insights into
the Wallace-Darwin relationship, practically accusing Charlie of intrigue to
prevent him getting glory for the discovery of natural selection. Whether either of them
deserved any credit is debatable. In the March-May 2004 issue of
Creation Ex Nihilo magazine, Russell Grigg argues that Charlie knew
about and plagiarized the idea of natural selection from half a dozen predecessors
and peers.
- Charlie Worship: In the 23 March issue of Current
Biology,4 interviewee Hugo J. Bellen (Baylor College of Medicine) is asked
if he has a scientific hero:
Yes: Charles Darwin. His ‘Origin of Species’ is in my opinion the most important text in biology that has been published so far. I have read The Origin three times and every time I am in awe at Darwins ability to integrate so many different facts in a simple coherent theory. The principle of natural selection has stood for over 150 years now. Its implications for biology and genetics are far reaching, and the theory still hugely dominates our thinking as biologists.
Follow the chain links on Darwin for differing views about this hero.
- Another Thing You Cant Live Without:
David Carling (Imperial College) provides a quick review of AMPK in the
23 March issue of Current Biology.5 If you dont
know what AMPK is (AMP-activated protein kinase), just be glad you (and
everything else alive) has it:
AMPK has been dubbed the cellular fuel gauge, because it is activated by a drop in the energy status of the cell. If ATP is used up faster than it can be re-synthesized, ATP levels fall and this leads to a rise in AMP. The increase in the AMP:ATP ratio triggers the activation of AMPK and leads to the phosphorylation of a large number of downstream targets. The overall effect of AMPK activation is to switch off energy-using pathways and switch on energy-generating pathways, thus helping to restore the energy balance within the cell. The conservation of AMPK throughout evolution emphasises its importance: homologs have been identified in all eukaryotic species examined to date, including plants.
Other recent articles have focused on this cellular fuel gauge as
a means of controlling appetite and obesity (see, for instance,
Nature April 1, 2004).
When asked Can we live without it, Carlin answers immediately,
Almost certainly not. Mice without it die in embryo, and
it cannot be mutated much: Although a complete loss of AMPK activity is
lethal, subtle changes in AMPK activity can lead to serious clinical consequences.
You dont say. How the first organisms got about without it, he doesnt say.
- Genome Size: Also in
Current Biology,6 Brian Charlesworth and Nick Barton examine the
question of why genome sizes differ so much between organisms, and offer a
suggestion:
Genome sizes vary enormously. This variation in DNA content correlates with effective population size, suggesting that deleterious additions to the genome can accumulate in small populations. On this view, the increased complexity of biological functions associated with large genomes partly reflects evolutionary degeneration.
But judging from the many puzzles, contradictory evidences and lack of
observations mentioned in the article, it doesnt appear that evolutionists
or creationists quite have a handle on this one yet.
- Intron Origins: Another paper in the same issue of
Current Biology7 attempts to put forward a hypothesis
about intron origin and
evolution (see 09/23/2003 headline).
Phylogenetic evidence [sic] indicates that these sequences have been targeted by numerous intron insertions during evolution [sic], but little is known about this process. Here, we test the prediction that exon junction sequences were functional splice sites that existed in the coding sequence of genes prior to the insertion of introns.
Again, neither side seems to have scored a touchdown on this question.
What are introns there for? If they evolved, why doesnt the cell
get rid of them, instead of using such complicated machinery to process them?
As to phylogenetic evidence, it is subject to evolutionary presuppositions.
Until we know more, we should not rule out the possibility that introns have a
function.
- Integrating Your Eyes and Ears: Martin S. Banks (psychologist,
Berkeley), explores the interaction of eyes and ears to help us make decisions.
In Current Biology,8, he gives an example of this complex
process we take for granted:
You enter a crowded room and someone calls your name. You turn to see who it is. You now see several people in the general direction the voice came from. Many are talking. Which one called your name? You hear it again and now the sound seems to come from straight ahead or nearly so. There are still a handful of candidates in your field of view, so you look from one to the other. Finally, you see one whose lips move as you hear your name once more. Sound and sight have come together and you identify the speaker as your college roommate. How does this work? That is, how does the brain find the appropriate auditory–visual correspondence to determine that a sound and sight have come from the same source?
He points to a recent study by Alais and Burr that produces an
important and seemingly pervasive rule for the combination of visual
and auditory cues to spatial location. Whatever it is, its
amazing.
- Thank God for Our Moon:
Lastly, an article in New
Scientist argues that without a moon like earth has, life could not exist.

Plenty of research material above for the curious. We hope Creation-Evolution
Headlines demonstrates to young people that there are still many scientific puzzles
to solve and will stimulate a few to become scientists. Despite their bluff
and bravado, the Darwin Party clearly doesnt have answers to some of the
most basic questions about stars, life, cells, and genes. Lets roll.

In Defense of Men and Women, Body and Soul 03/31/2004
The BBC News
published a male-bashing article by Baroness Susan Greenfield, Director of
The Royal Institution, on March 29. It must have created a stir,
because the
next day,
Prof. Steve Jones of University College, London, tried to restore the male ego.
This was apparently a two-part documentary exploring what would happen
If women ruled the world.
Greenfield had alleged that women will outperform men in 20
years, no longer have need of male muscle power, and have lots of
alternative methods for bearing and raising children.
Her dismissal of men was just slightly less than total:
More probably, it is not so much that men could be extinct, as opposed
to our family lives changing dramatically, she said. They
might be useful to keep around as historical curiosities.
Jones responded with an article illustrated with a superman cartoon.
The caption read, Superhero or zero? Professor Jones says men are
indispensable. His point, however, reeks of Darwinian
kryptonite and seems unlikely to make his buddies feel able to leap tall
buildings in a single bound:
In fact the question of males raises not one, but many
biological issues: the origin of sex, of distinct sexes, of why there are
only two sexes rather than dozens.
And how is that pastime maintained, given that it is so
expensive? A woman, it seems, could much increase the rate at which she
copies her own genes if she avoided having them diluted by those of a man.
Yes, men are a complicated lot, and theres a lot we do
not know. As we look through the living world, one thing is clear: it
is very hard to get rid of them.
The best justification Jones seems to come up with for being male is that
men enable the human race to shuffle the genetic cards. Organisms
without both sexes seem to come to an evolutionary dead end, he claims.
So since women cant get rid of the louts, they might as well tolerate
them.
If you can keep your head while all about you are losing
theirs and blaming it on you ...
Yours is the Earth and everything thats in it,
And - which is more - youll be a Man my son.
-- Rudyard
Kipling
These BBC articles would make Dr. Dobson hopping mad.
And they should make any red-blooded man or woman upset.
This is really ugly. It illustrates the utter devastation Darwinian thinking
has foisted on our culture. Greenfields comments disparage
the Royal Institution, which was brought to its pinnacle of
prestige by an unselfish, honorable, God-fearing, hard-working man: Michael
Faraday.
Male chauvinism is wrong, but so is female
chauvinism whats bad for the gander is bad for the goose.
Neither of these articles has restored any dignity to men or women.
Darwinism has reduced males and females to gene-propagating commodities.
Carl Sagan expressed the Darwinian view of humanity in black ink:
In a very real sense human beings are machines constructed by the
nucleic acids to arrange for the efficient replication of more nucleic
acids. In a sense our strongest urges, noblest enterprises, most
compelling necessities, and apparent free wills are all an expression of
the information coded in the genetic material: We are, in a way,
temporary ambulatory repositories for our nucleic acids. This does
not deny our humanity. It does not prevent us from pursuing the
good, the true, and the beautiful. But it would be a great mistake
to ignore where we have come from in our attempt to determine where
we are going.
The Cosmic Connection (Dell 1960), p. 6.
Talk about schizophrenia; he just denied our humanity and then said it
does not deny our humanity. He used his free will to deny that we
have free will. He left the good, the true,
and the beautiful as undefined terms, and reduced our noblest
enterprises to the action of selfish genes. This is the legacy of
Darwinism, of which Sagan was one of the staunchest evangelists.
It leaves humanity as nothing more than gene-replicating machines
accidentally emerging from nothingness and headed nowhere. How
can machines attempt to determine where we are going?
Want to know where we are going if Darwinism is true? To the
grave, where consciousness and intelligence and noble enterprises
are extinguished, returning to the nothingness from which they emerged.
Had enough? Good. Forget Sagans cynical
and depressing view, because he contradicted himself. The only way
he could make his point was to cheat: he borrowed words from a Christian
vocabulary (good, true, beautiful, noble, information, free will, etc.).
Thus, he shot his straw man in the foot. If he really believed what he
was saying, he would cry
Vanity
of vanities, all is vanity in despair. He would
realize that his own noble enterprises, whether writing books, exploring
Mars or appearing on the Johnny Carson show, were all emptiness and striving after wind.
He would just have sex (to help out the selfish genes) and then die.
And forget the BBCs rant against maleness, which would have even robbed
him of the joy of sex. Forget, too,
Jones wimpy comeback. All these ideas are worthless,
built on a foundation of Darwinian shifting sand. Darwinians cannot answer
any of the questions they raised: the origin of sex, of distinct sexes,
of why there are only two sexes rather than dozens, and why sex persists
when it is so expensive (see 04/14/2003
headline, for example). Sex and gender roles are incomprehensible to a
Darwinian, because they have no solid foundation for ultimate meaning.
Heres the first step for restoring your worth as a real man, or a real
woman: keep your head, like Kipling warned. Dont fall for Darwinian
propaganda. Its contradictory, unsupported by evidence, and leads to
despair. You have a soul, brother; you have a soul, sister; and being
a man or woman is all about soul. Souls did not evolve.
To the degree Darwinism degrades humanity, the Bible
restores it, and then some! God Himself took our physical bodies He
had formed by His intelligent design, and breathed into them the breath of life,
and we became
living
souls. Human beings, both male and female, were
inscribed with the image of God, unlike anything else He had made.
Your purpose is not just to pass on your genes and die. You have worth
as an individual. You are responsible as an individual for what you
do with your life. You, as an individual, will face the judgment of
your Maker.
Physically, God made men and women to need and desire one another.
All higher animals propagate by sexual reproduction, but with humankind,
God instituted the family as a means of passing
on His commandments to future generations, and gave sexual reproduction
a spiritual and emotional meaning beyond mere procreation, as a picture
of love something animals, without Gods image, cannot
experience.
He assigned roles to men and women appropriate to our natures.
But spiritually, He made us much more than mere sexual dimorphisms
of an animal species.
Because of His image we bear, we have minds, and language, and the
possibility of meaningful relationships. We can think, reason,
speak, write, communicate, and love.
His two great commandments are for men and women:
to love
God with all our heart, soul,
strength and mind, and to love our neighbor as ourselves.
As His creations made in His image, we are going to live forever.
Eternity will be either with or without our Creator, depending on our response to His
call. By default it will be without Him, because
we have all sinned. But because the Lord loved us, He offered His Son
as a sacrifice to redeem us from our sins. This is the good news of the
Word of God to us: He offers us reconciliation, without penalty, as
a gift. You can receive this gift by turning from your sin and placing
your trust, your empty hands of faith, into his strong hand of salvation.
That can be the start of a new life, a new relationship with your Maker.
Just how great His love to us was only
hinted at in the recent blockbuster movie The Passion of the Christ.
The movie quoted Jesus proverb and promise from
John 15,
Greater love hath no man than this, that a man lay down his life for his friends.
Ye are my friends, if ye do whatsoever I command you.
The remembrance of that passion of Christ, and the subsequent glorious
resurrection, is approaching. The contrast between the two world views
the dismal, meaningless, gene-propagating Darwinian world expressed by
Sagan and the BBC articles, and the rich relationship between men, women
and a heavenly Father taught in the Word of God
could hardly be more stark. One leads to death, one to life.
So choose life: wont you repent of your sin, and
receive Him today? Then you can find fulfillment and abundant life
as a man or woman of God.
Homework: Watch The Passion of the Christ, then come home and
read how it was prophesied 700 years before it happened by Isaiah
(read Isaiah
52-54, esp. ch. 53). Then read Jesus explanation of why He came
and the importance of being born again by believing (trusting) in Him, in
John
ch. 3. To take your belief to the point of commitment, read the
Apostle Pauls instructions in
Romans
10. Then for a real encouragement, and in preparation for Easter,
read what is in store for those who trust in Christ by reading
I Corinthians
15, the great resurrection chapter of the Bible.
When you get to the last verse, you will see why pursuing the good,
the true, and the beautiful, is indeed a noble enterprise for the redeemed:
whether man or woman, boy or girl.
If you have any questions understanding these things, write here.

Arecibo SETI Project Draws a Blank
03/31/2004
Project Phoenix, a 10-year project searching
for evidence of extraterrestrial intelligence, found nothing, reports
the BBC News.
The project used the worlds most powerful radio telescope at Arecibo,
Puerto Rico, to scan 800 nearby stars for signals.
Project manager Peter Backus claims the team has learned a lot about
searching for ETI, but concludes we live in a quiet neighborhood.
No need to feel lonely. There is
someone out there attempting to make contact. Its your
Creator.
Read the uncoded message in
Isaiah
55. He uses a private wavelength called prayer. You dont
need expensive instruments. You dont need to send coded messages,
and you dont need to wait thousands of years for the answer.
Its the fastest medium of communication in the universe, faster than
light: so fast, in fact, that
the Recipient answers
before the call.
All Carl Sagan could hope for in Contact was a temporary fellowship of
commiseraters waiting for the heat death of the universe. The living
God offers a fountain of eternal
life. Choose today. Dont hesitate; seek the Lord while
He may be found.

Whoops; Coelacanth Not in the Family Tree 03/30/2004
Sorry; they looked like they were evolving. The ungainly coelacanth, long
thought extinct but then discovered alive and well in the Indian
Ocean in the 1920s, had bony fins that evolutionists presumed were forerunners
of limbs. Now, a report in PNAS1 says lungfish instead
were the distant ancestors of us and our fellow land vertebrates.
The authors, Brinkmann et al.,
considered their work a valiant attempt to solve a big problem:
The colonization of land by tetrapod ancestors is one of the major
questions in the evolution of vertebrates. Despite intense
molecular phylogenetic research on this problem during the last
15 years, there is, until now [sic], no statistically supported answer
to the question of whether coelacanths or lungfish are the closest living
relatives of tetrapods. (Emphasis added in all quotes.)
They compared the DNA of two genes in three lungfish groups and with
coelacanth, and despite some puzzling results, tipped the ancestry score
to the lungfish based on
high bootstrap values, Bayesian posterior probabilities, and
likelihood ratio tests.
1Brinkmann et al.,
Nuclear protein-coding genes support lungfish and not the coelacanth
as the closest living relatives of land vertebrates,
Proceedings
of the National Academy of Sciences USA, 10.1073/pnas.0400609101,
Published online before print March 22, 2004.
OK, so they get their publication in one
journal before someone shoots it down somewhere else. You can pick
the genes that give you the results you want, if you massage them thoroughly
with heavy doses of imagination while under the influence of Darwin whiskey.
What a crazy way to do science. Now anybody with a PhD
and a knowledge of fancy jargon and mathematical hand-waving tricks can
build a fictional account of the unobservable past that can never be proven.
As long as it might be true (provided we can massage away the
protruding bones) its good enough to be published. Should this
be called science, which most people assume has something to do with
discovering truth? Look at this example of what these authors do in
their paper when one of their methods doesnt produce the desired
result. The details dont matter, the medium is the massage:
The ML-based [Maximum-Likelihood] method (QP) shows generally high
support values for all inferred branches, with three exceptions:
(i) the nodes supporting the monophyly of lungfishes, (ii) the
node supporting the sistergroup relationship of tetrapods and
lungfishes, and (iii) the node supporting the monophyly of the
Sarcopterygii (44%). Part of the problem can be explained by the
surprising result that TREE-PUZZLE supports an obviously [sic]
artificial
monophyletic group of Neoceratodus and the coelacanth
with the highest value of 48% in this region of the tree. It is
known [sic] that the TREE-PUZZLE program is rather sensitive to
pronounced differences in evolutionary rates because of the
quartet approach. The African and the South American
lungfishes evolve quite fast [sic], and the Australian lungfish and the
coelacanth sequences evolve comparatively slower [sic]. This constellation
of pronounced differences in evolutionary rates may lead
to an artificial grouping of sequences with similar evolutionary [sic]
speed (usually the slowly evolving ones [sic]). Often a more basal
position of the fast evolving [sic] lineages due to long branch attraction
effects will result, because these faster sequences are
‘‘pulled’’ toward the faster evolving [sic] sequences at the root, i.e.,
outgroup of the tree. This explains [sic] why the highest support of QP
among basal Sarcopterygii (48%) seems to favor a clearly
incorrect grouping of Neoceratodus and the coelacanth, again
supporting the notion that QP might not be the most
appropriate method for this phylogenetic problem.
So well just explain away the data that dont fit our preconceived
notions and adjust the imaginary parameters (evolution rates)
till we get a semblance of congruence. Tweak, tweak, tweak.
The rest of the article uses copious wiggle words might,
probably, possibly, support, etc. Molecular phylogeny is just
a game Darwin Party members like to play, because it has no possibility of
a winner (see 07/25/2002 headline).

evolution, see 07/30/2002,

Swamp Gas Found on Mars
03/30/2004
The European Space Agencys
Mars
Express orbiter has confirmed earlier detections of
methane in the Martian atmosphere, according to the
BBC News.
Because methane could only exist in the atmosphere for a few hundred
years, there must be a source that replenishes it.
Two sources have been proposed: active volcanos, or living organisms.
The BBC is hopeful it is the latter, titling its article, Methane
on Mars could signal life.
Nature
Science Update is more cautious, however, asserting that the low levels
of methane detected rule out the idea of life spread all over the planet.
Instead, it might be leaking from dormant volcanos.
Science
Now is not sure the methane spectra are definitive yet.
They found methane hissing out of crevices
in deep mines on Earth, too (see
04/08/2002 headline), and thought
it was a missing link in the evolution of life. The
same comments apply.

Jaw Mutation Led to Human Brain 03/29/2004
The science news outlets like
Science
News seem to all jump on human evolution stories more
than evolution stories about other life forms. Maybe thats because
were only human. This weeks entry concerns a story published
in Nature1 by Stedman et al2
that a muscle protein mutation might
be correlated with a change in brain size among human ancestors.
The idea is that this change reduced the stiffness of the jaw, shrinking the
massive jaw muscles of gorilla-like primates, and therefore allowing brain size
to grow.
A change in a single muscle protein may have been a key step in the
evolution of modern humans, according to a new theory, echoes
Elizabeth Pennisi in Science3.

Science
Vol 303, Issue 5666, 1957 , 26 March 2004, DOI: 10.1126/science.303.5666.1957a.
If you swallow this line, weve got
a resort vacation to sell you on the Isle of DeBris. The reaction of
Ralph Holloway, a physical anthropologist at Columbia University, is more
calm and rational: To suggest that the brain is constrained by chewing muscles is
just rubbish.
This tale is a pinhead balanced on a house of cards in a
windstorm. It relies on mythical dating methods and flexible estimates
of mutation rates, all supported by the assumption of evolution. We
are not impressed by one putative mutation that might have made
miracles possible (Stedman sidestepped in the Science
article, Were not suggesting that this mutation alone [buys]
you Homo sapiens, but it could make possible brain growth).
We want to see the catalog of 50,000 or more lucky rolls of the die that
supposedly turned a gorilla-like knuckle-walker into a philosopher.
Pete Currie has the gall to open his report in Nature,
Darwins mouthpiece (see 03/04/2004
commentary), with this distortion:
Ever since Bishop Wilberforce famously ridiculed [sic] the possibility that
man was descended from apes, and T. H. Huxley bravely [sic] chose primate
ancestry rather than ignorance [sic], the debate over our origins has claimed
a special place in evolutionary theory. With the acceptance by
most of us [sic] that we are indeed [sic] a product [sic] of natural
selection [sic], discussions surrounding the issue have cooled [sic]
somewhat. But exactly how natural selection acted to produce
the modern human form has remained hotly contested.
(Emphasis added in all quotes.)
Fact is, no one recorded the actual words spoken in the famous interchange
before the British Association at Oxford in 1860, and many if not most in
the crowd sided with Wilberforce. The debate has become somewhat of
an urban legend, more symbolic than substantial (see Janet Brownes
account, Charles Darwin: The Power of Place, ch. 3).
Most of us? Speak for yourself, Pete. Only a few
elitist Darwin Party members think the intricacies of human soul, spirit
and body can be produced by natural selection. But of course, they
have far more faith and more vivid imaginations. Thats why they
are evolutionists. If you think
this is an unfair tirade against the X Clubbers, look what Currie
himself confesses at the end of his article about not just the fossil record
of human evolution, but of all evolution:
What is the significance of these findings, and do they shed any light
on human origins? Although there is a rough consensus [see
12/27/2003 headline]
about the individual features that define fossil species within the
genus Homo, the sequence in which individual traits were acquired
[sic] during hominid evolution [sic] remains controversial.
Furthermore, the definition of which character traits were essential
for the appearance [sic] of the modern human form is equally
contentious. The reasons for this are familiar to anyone
who tries to explain morphological transitions [sic] over large evolutionary
distances [sic] based primarily on the fossil record. Such
explanations hinge on finding so-called transitional
forms, where a particular fossil is [sic] so indelibly etched with
the tell-tale signs of what something was, and what it was going to become [sic],
that an inescapable evolutionary theory simply tumbles out of the dirt.
Not unsurprisingly, such fossils are very rare indeed, and fossils
charting the course of hominid evolution [sic] are no exception.
There you have it. He has just admitted that transitional fossils
are rare indeed. so rare that a senior paleontologist at the British
Museum once
laid it on the line:
there is not one such fossil for which one could make a watertight
argument. Though an evolutionist, Dr. Colin Patterson
continued by criticizing a
bad habit of his brethren: It is easy enough to make up stories
of how one form gave rise to another, and to find reasons why the stages
should be [sic] favoured by natural selection. But such stories
are not part of science, for there is no way of putting them to the
test.a
Deliberately and connivingly, the Darwin Party injected
just-so storytelling into science
(see 12/22/2003 commentary).
Its time to vote the rascals out.

aThe mockers at talk.origins
lambaste creationists for using this old quote, accusing them of taking
it out of context. But read the entire quote, and then
watch them squirm their way around it, trying to make us believe
Patterson really didnt mean what he clearly said.
If they want to dredge up Huxley and Wilberforce in 1860, why not
Patterson in 1981?
As an evolutionist, of course Patterson could afterwards
claim his words were

Even the mockers agree that the quote was accurate, at least in the

accused it of being positively anti-knowledge.
It was an honest and damaging series of admissions he made in front

Trying to make Pattersons words concern only systematics

How Could Polar Dinosaurs Survive Freezing, Darkness?
03/29/2004
National
Geographic News has a report about a new exhibit of
dinosaur fossils that have been found in the northern and southern polar regions.
These unusual creatures had to survive not only the cold, but also,
due to the effects of orbital mechanics, six months of darkness each
year. Intrepid explorers in south Australia, northern Canada,
Patagonia, Alaska and Antarctica have braved the elements since the 1980s
to find dinosaur bones in the extreme polar regions. Their discoveries
have changed our conceptions of dinosaur metabolism and the ecosystems
in which they lived. Polar dinosaurs include:
- Hypsolophodontids: small, speedy, plant-eating dinosaurs that
ran on two feet. They had large eyes, apparently adapted to
low light levels, and bones that grew throughout the year, suggesting
they were warm blooded. The plants on which they fed apparently
did not drop their leaves during the winter.
- A horned dinosaur named Serendipaceratops arthurcclarkei (no
kidding) must have looked like something out of a sci-fi movie.
NG claims this is one of the oldest horned, or frilled, dinosaurs
known, which suggests that horned dinosaurs may have originated in the
southern polar region.
- A sauropod, possibly the largest found in Antarctica, is being
analyzed. It was found at 13,000 feet elevation.
- An allosaurus-like meat eater named
Cryolophosaurus ellioti was 22 feet long.
The exhibit at Seattles Burke Museum is called Dinosaur
of Darkness.
Throughout the world there are mysteries.
Fossils give silent evidence of a very different world in the past; a world
with polar regions that must have supported lush plant life and rich ecologies
of diverse plants and animals larger than those living today. Large redwood
stumps have also been found in the Arctic circle
(see 03/22/2002 headline),
and there are the legendary frozen mammoths of Siberia.
This article suggests that
the climate was warmer then than it is now, but puzzles over the
fact that these dinosaurs must have endured months of darkness and
temperatures that plunged below freezing. For plants to have
supported herbivores and carnivores of this size near the poles,
it would seem there must have been atmospheric conditions that evened out
the lighting and temperature.
As for horned dinosaurs originating near the south pole,
we laugh, ha ha, at this funny joke.

Mars Salt Water Predicted 03/28/2004
Planetary scientists have been very excited about the
Mars
Exploration Rovers discovery of evidence that
salt water existed on Mars in the past. Not too many seem to be
noticing, however, that this was predicted by a creationist.
Dr.
Walt Brown predicted in 2001, Soil in erosion channels on Mars
will contain traces of soluble compounds, such as salt from the
subterranean chamber. Soil far from erosion channels will not.
Dr. Brown has also made other
predictions about water on Mars based on his hydroplate theory.
Visualize a salt water sea while looking at this
magnificent panorama

Dr. Brown (see
January featured scientist)
has been one of few makers of
scientific models to put his reputation on the line and make predictions.
This is not the only one of dozens he made in his book
In the Beginning that have
been confirmed. If detailed predictions of a model seem to be corresponding to
reality on repeated occasions, it should cause other scientists to take
notice.

Animals Are Overengineered for Navigation 03/23/2004
Animals outshine us in many ways, but one capability that should humble us
is animal navigation. From spiders to mice, from birds to bees, the ability
of animals to find their way around is truly astonishing, and James L. Gould
of Princeton
has raised our awareness of just how astonishing in a short article in
Current
Biology (March 23, 2004).1
He starts by explaining that navigation is more than just
knowing which way you are pointed: Nearly all animals move in an oriented
way, he says, but navigation is something more: the directed
movement toward a goal, as opposed to steering toward or away from, say,
light or gravity. Navigation involves the neural processing of
sensory inputs to determine a direction and perhaps distance.
(Emphasis added in all quotes.)
As an example, he mentions how honeybees have to correct for the angle of the
sun from morning to afternoon. This involves much more than orienting at a
fixed angle. The bee has to use changing sensory information to maintain
its internal map.
Gould mentions four stumbling blocks that prevented early
investigators from appreciating the navigational abilities of animals.
Researchers apparently assumed natural selection was sufficient to
explain it all. He writes, Several trends reflecting favorably on natural
selection and poorly on human imagination characterized early studies of
navigation. The stumbling blocks investigators have had to
get over include:
- Spectral Breadth: Early researchers assumed that animals were limited
to our own human senses, but found out they can utilize a shopping list of cues
invisible to us: ultraviolet light, infrared light, magnetic fields,
electric fields, chemical pheromones, ultrasonic sounds and infrasonic sounds.
We were blind to our own blindness, he says, and there is
no reason to assume the list is complete.
- Complexity: Another crippling tendency of early investigators
was what navigation pioneer Donald Griffin called our innate ‘simplicity
filter’: the desire to believe that animals do things in the least complex
way possible. Perhaps it was from our own pride of place, but
according to Gould, we should be humbled:
Experience, however, tells us that animals whose lives depend on
accurate navigation are uniformly overengineered. Not only do
they frequently wring more information out of the cues that surround them
than we can, or use more exotic or weaker cues than we find
conceivable, they usually come equipped with alternative strategies
– a series of backups between which they switch depending on which
is providing the most reliable information.
- Recalibration: Early studies assumed animals just needed to learn
a trick once (a phenomenon called imprinting, true in some short-lived
animals.) Then they found out that some animals are able to recalibrate
their instruments.
- Cognition: The school of psychology known as
behaviorism, which denies instinct, puts a ceiling on the maximum level
of mental activity subject to legitimate investigation, Gould chides.
As a result of this bias, most researchers deliberately ignored
or denigrated the evidence for cognitive processing in navigating
animals. Not all animals exhibit cognitive intervention,
Gould admits. But he then makes a very unDarwinian countercharge:
However, the obvious abilities of hunting spiders and
honey bees to plan novel routes make it equally clear that
phylogenetic distance to humans is no sure guide to the sophistication
of a species orientation strategies.
He gives an example: One of the problems we inherited
from behaviorism was the assumption that exploratory behavior must be
rewarded. However, many species examine their surroundings voluntarily
and, in fact, do so in detail. (See example on mice below.)
Lets look at just a few of the believe it or not examples
Gould showcases in the article:
- Honeybees: Here is an example of switching inputs to get
the most reliable information. A honey bee, for instance, may set
off for a goal using its time-compensated sun compass. When a
cloud covers the sun, it may change to inferring the suns position from
UV patterns in the sky and opt a minute later for a map-like
strategy when it encounters a distinctive landmark. Lastly, it may
ignore all of these cues as it gets close enough to its goal to detect the
odors or visual cues provided by the flowers.
- Mice: Here is an example of the overengineering
Gould spoke of. Many field animals, like mice, have a strong drive to
acquire information about their home range in advance of need, whether or
not (as behaviorism would expect) they get an immediate reward.
Consider mice, he says,
which not only gallop endlessly in
running wheels, but actually prefer difficulty, such as square ‘wheels’, or
wheels with barriers that must be jumped. Given a 430 meter long opaque
three-dimensional maze of pipes, mice will work out the shortest path within
three days, and without reward.
Navigation requires determining direction:
This can be achieved in two ways, and mice use both: they can use
another landmark from their mental map and triangulate
the direction of the goal, or they can use a landmark-independent compass
like the earths magnetic field.
--and they never joined the boy scouts. Whats more, mice
can also navigate perfectly well, even if the habitat fails to
provide useful landmarks. They will remember the
direction and length of each leg of their outward
journey and integrate the result when they are ready to return and
set off home, even without a trail of bread crumbs.
- Pigeons: Daytime provides celestial cues. ...once
the relationship between azimuth and time of day is memorized, Gould
says, the animal has a highly accurate compass. Weve
all heard about the navigational feats of homing pigeons. They can
discern ultraviolet (UV) light, which accentuates polarization patterns of scattered
sunlight, for drawing their mental map, and add to it individual data points
like the average of a nights attempts to escape from a cage, or
some other directional measure. The cues help them derive a mean vector,
with direction pointing to the goal, and length representing scatter.
When all the cues line up, theyve got their bearing.
- Migratory birds: Birds who migrate between nesting grounds
and wintering grounds can use sun cues, star cues, magnetic fields and
landmarks to find their way. Not only that, they can recalibrate the
cues for seasonal changes, latitude, and longitude. This requires
recalibration:
To infer the pole point through broken clouds, the animals map
of the sky must be updated. And as the migrants move south
in the fall, new sets of stars in the southern sky appear, while
northern stars slip below the horizon. Clearly, changes in both
season and latitude make relearning the stars essential.
Only fairly recently has this constant updating been demonstrated.
In fact, for unknown reasons, nocturnal migrants calibrate their star
pole to the magnetic pole. Instead of simply taking the pole point as
the true guide, the birds constantly recalibrate the magnetic pole to the
geographic pole, and then the geographic pole to the magnetic pole.
- Latitude: Fish, turtles, lobsters, and birds all determine their latitude
by the angle of the magnetic field. In theory, Gould says,
animals could obtain the same information from the suns noon
elevation, but I know of no case in which this traditional human solution
is used. The critters must know something we dont.
- Longitude: house wrens, pigeons, sharks, salmon, sea turtles and spiny lobsters
have all conquered a navigational problem that bedeviled human
navigators until very recently, the problem of determining longitude.
How do they know distance east from west?
How can house wrens find their way back, unerringly, to the same nest box after
a long flight at a different time of year from when they left?
The apparent answer to this conundrum is provided
by a map sense, Gould answers. The earths magnetic field
provides both a map and a compass just the tools you would need if
released in an unfamiliar area.
- Pigeons again: When homing pigeons circle around
before heading home, they are reading the local map of magnetic
gradients and extrapolating it from the one they learned at home.
How do pigeons detect the earths magnetic field? They actually
have magnetite grains in their heads, in the ethymoid sinus.
Experiments have shown that magnetic anomalies make the birds disoriented.
A sharp pulse of magnetism can severely impair their compass. But
remagnetize the organ by putting it into a magnetic field, and the bird is
back to normal
Gould ends by pointing out two of the biggest challenges to researchers
studying animal navigation: (1) the nature of the map sense, and
(2) the issue of recalibration, which is still puzzling.
The interaction of these specific learning programs,
he promises, doubtlessly holds many magnificent secrets.
1James L. Gould, Magazine: Animal Navigation,
Current
BiologyVol 14, R221-R224, 23 March 2004.
Wow. Thank you, Dr. Gould.
This article contains absolutely no hints about how such abilities could have evolved;
in fact, it contains a couple of off-handed swipes at the notion that
natural selection could explain them, or that skill correlates with
phylogenetic distance. This is surprising, considering
that James L. Gould is a member of the Department of Ecology and Evolutionary
Biology at Princeton. It could just as well have been written by
Dr. Gary Parker at the Institute for Creation Research. Its
a wonder the editors of Current Biology let this one get by without
the required pinch of incense to Emperor Charlie.
Notice that these highly refined and accurate navigational
skills are possessed by a wide variety of animals: mammals (e.g., mice),
insects (e.g., Monarch butterflies -- see 05/23/2003
and 07/09/2002 headlines),
birds (e.g., Pacific golden plovers, which can navigate over open sea to the
Hawaiian islands without having ever seen them), reptiles (e.g., sea turtles),
crustaceans (e.g., lobsters), and fish (e.g., salmon). Skill does not scale with
presumed evolutionary advancement: for instance, the spiny lobster wins
the prize for magnetic mapping (see 01/06/2003
headline). Even bacteria and plants can orient
themselves with respect to environmental cues. Humans were given
ability to build tools that can navigate a spacecraft to Saturn, but we
must surely stand in awe of a God who could put technology
that outperforms NASA into a bird brain. This article goes to show
that the film Incredible
Creatures That Defy Evolution could become an infinite series.

Stupid Evolution Quote of the Week: Cell Networks
03/22/2004
A team of Chinese scientists analyzed protein interactions in yeast cells,
and titled their paper in PNAS1
The yeast cell-cycle network is robustly designed.
They demonstrated that the cell-cycle network is extremely stable
and robust for its function, and able to survive perturbations.
The beginning of the paper expresses the wonder the stimulated their research:
Despite the complex environment in and outside of the cell,
various cellular functions are carried out reliably by the
underlying biomolecular networks. How is the stability of a cell
state achieved? How can a biological pathway take the cell from
one state to another reliably? Evolution must have played a
crucial role in the selection of the architectures of these networks
for them to have such a remarkable property.
(Emphasis added in all quotes.)
After analyzing the stable states, big attractors and checkpoints
in the yeast cell cycle, the scientists remind us that this network is part
of an even bigger marvel:
Note that the network we
studied ... is only a skeleton of a larger cell-cycle network
with many ‘‘redundant’’ components and interactions....
Thus, we expect the complete network
to be even more stable against perturbations.
... Furthermore, our results suggest that not only do biological states
correspond to big fixed points but the biological pathways are also robust.
Functional robustness has been found in other biological networks,
e.g., in the chemotaxis of E. coli (in the response to external
stimuli) and in the gene network setting up the segment
polarity in insects development (with respect to parameter changes)
. It has also been found at the single molecular level, in the
mutational and thermodynamic stability of proteins. In some
sense, biological systems have to be robust to function in complex
(and very noisy) environments.
And now to the climax. In the closing statement, after claiming several
times that these networks are robustly designed (their term),
they suggest that all this complexity, all this robustness, all this
control and regulation is the product of time, chance and contingency.
In fact, the very robustness might even help evolution make it better:
More robust could [sic] also mean more
evolvable, and thus more likely to survive [sic]; a robust ‘‘module’’ is
easier to be modified, adapted, added-on, and combined with
others for new functions and new environments. Indeed,
robustness may provide us with a handle to understand the profound
driving force of evolution.

Congratulations to the winners of this weeks Stupid Evolution
Quote of the Week. Bravo. Now call the schizophrenia ward.
They may actually have a point. In the church, Christians
are more likely to survive, and are easier to be modified, augmented, adapted
and combined with others for new functions and new environments in the body of Christ if they
are more evolvable (malleable) in Gods hand.

can be perfected in weakness, but only by intelligent design.

More Details of Photosynthesis Coming to Light 03/20/2004
Photosynthesis, the light-harvesting capability of plants, was a black box
30 years ago, but more and more details have been elucidated by advanced
probing techniques. In the
March 18 issue of Nature,1, a team of Chinese scientists
determined the X-ray structure of a principal component acts like a light-harvesting
antenna. The structure utilizes special molecules that not only gather
the energy of light, but also get rid of excess energy that could damage the
plant. They write, Four carotenoid-binding sites per monomer have
been observed. The xanthophyll-cycle carotenoid at the monomer–monomer
interface may be involved in the non-radiative dissipation of excessive
energy, one of the photoprotective strategies that have evolved in plants.

Crystal structure of spinach major light-harvesting complex at 2.72 Å resolution,
Nature 428, 287 - 292 (18 March 2004); doi:10.1038/nature02373.
Nice observation, but another example of the Darwinian bad habit of
assuming what ought to be proved. Plants dont evolve
protective strategies. That requires intelligence.

Do Birds of a Feather Demonstrate Parallel Evolution?
03/19/2004
A puzzling phenomenon emerges from evolutionary considerations of bird
plumage coloration and patterning. Hopi E. Hoekstra and Trevor Price
describe the problem in the March 19 issue of
Science1
and provide examples:
The pages of any bird guide reveal a spectacular diversity of colors and
color patterns. Although color patterns vary within species, often
they also distinguish closely related species. Variations in color are
thought to have evolved through the interplay of sexual selection
and natural selection. What is less obvious--because
the birds are on different pages of the guide--is the repeated appearance
of similar color patterns among distantly related species
(parallel evolution) [sic]. A list of 9672 of the worlds bird
species includes a black-capped chickadee, a black-capped pygmy tyrant,
and a black-capped kingfisher as well as 26 other species whose most
conspicuous feature--at least prominent enough to prefix their common
name--is a black cap. There are 41 black-throated species (in 40
different genera), 8 that are blue-capped, 9 that are orange-breasted, and
29 that are red-billed. There are many such examples of parallel
evolution in birds [sic], but the molecular underpinnings of
similar plumage patterns among distantly related or unrelated species
are still not clear.
(Emphasis added in all quotes.)
Hoekstra and Price take encouragement from a study published in the same
issue of Science by Mundy et al.2 The team
identified a single mutation present in two unrelated birds that affects the
degree of melanism (dark coloration) in their plumage. This can only
be a partial solution, however, because they point out that
More than 100 genes that affect the amount and distribution of melanin
in the pelts of laboratory mice have been identified; presumably a similar
diversity of genes influences melanin production in birds.
However, they take heart that a single amino acid mutation in the one gene
studied correlated perfectly with the color variation in the two species:
one an Arctic skua, the other a snow goose. They conclude
that The repeated implication of this same gene suggests that there
may be a more limited number of genetic mechanisms to produce dark plumage
in natural populations than is suggested by genetic studies of lab mice
at least in this case.
An illustration Hoekstra and Price included shows another
remarkable example of parallel evolution among orioles. Two nearly
identical species are more distantly related, according to molecular
phylogeny, than dissimilar ones. Its as if we were shown two
pairs of identical twins, Moe and Joe, and Cindy and Mindy, and told that
Joe is more closely related to Cindy, and Moe to Mindy, than the other
way around. Within the oriole group, there are many such
examples of similar plumage patterns among different species due to
parallel evolution [sic], the caption reads.
The authors are hopeful that the work of Mundy et al.
will lead to solutions to these puzzles. Field studies of
selection, coupled with characterization of the melanin pathways in each
species, will eventually enable a closer tracing of the roles of
selection and mutation in generating the similarities and differences
between the species, they say. Further down the road,
we should be able to dissect the genetic basis of more complicated
color patterns like those of the orioles.

Conserved Genetic Basis of a Quantitative Plumage Trait Involved in Mate Choice,
Science
03/19/2004, 2004 303: 1870-1873.
The Natural Law of the Medes and the Persians in their model is evolution, even
when it contradicts other laws. Evolutionists cling to their mythical
phylogenetic trees like astrologers to horoscopes, but the data suggest a
different paradigm: a sharing and sorting of information
among different species, leading to traits like black caps, wing stripes, crests,
speckles, throat patches, iridescence (see photonic
crystals, 01/29/2003) and much more traits that look designed.
The observations do not support
a common ancestry cosmology, tweaked with epicycles like convergent evolution
and parallel evolution. When you see common design, why not
postulate a common designer?
The authors freely admit that just to get dark color requires
a complex set of molecular machines:
The melanocortin-1 receptor (MC1R)
resides in the membrane of specialized cells known as melanocytes, which are
the site of melanin synthesis in birds and mammals. Circulating
melanocyte-stimulating hormone (MSH) binds to MC1R, turning on the cells
melanin-making machinery.
Are we being asked to believe that up to a hundred
molecular machines that control just the melanin pigment all
evolved in parallel to produce nearly identical species? What about the
hundreds of other genes that produce throat patches, wing bars, and other
plumage patterns and colors? Visualize the exquisite patterns on a peacock,
bird of paradise, crane, red-winged blackbird, parrot, ostrich, ruby-throated hummingbird,
bald eagle, emperor penguin, magpie, rooster or the songbird
in your back yard. These patterns dont just happen; they
all require genetic information. This information is transmitted reliably,
with only rare slight variations, for many generations.
Mundy et al. are confident that they have identified
a rare example where the major molecular genetic determinant of a
quantitative trait has been identified in wild populations, and that
their work on snow geese and Arctic skuas provides strong support for
the notion that, at least in the case of melanism in birds,
evolution is driven by mutation rather than selection on
existing standing genetic variation. Nevertheless, to make
their story work, they have to wave three hands:
This presumably reflects some combination of a high mutability to
functionally novel MC1R alleles, a relative absence of deleterious pleiotropic
effects of these alleles, and the visibility of dominant or codominant
melanic MC1R alleles to natural selection. OK, if you want
to call that science, lets put some quantitative numbers in the
equation and test it, instead of bluffing about some combination of
multiple unknowns. On top of all their other contradictions,
they expect us to swallow their line about
a conserved mechanism of plumage color evolution through many tens of
millions of years of avian history, after they just told us the
gene they studied must have been highly mutable!
The phylogenetic explanation clearly has serious problems,
and this one hyped correlation is trivial. Even if these
evolutionists could establish that orioles diverged from a common ancestor,
they are still orioles: still able to
fly, eat, lay eggs, and do all the things birds are so good at, whether or
not their feather colors are a little darker in one population than another.
Sorting of existing traits has nothing to do with Darwinian evolution in
the sense of producing new genetic information. Something has
sorted and distributed pre-existing complex specified information in bird feathers,
creating beautiful patterns and colorful artwork.
That something could be intelligent design.
Parallel evolution is
just a hand-waving term to describe an observation, not explain it.

Butterflies in Amber Stun Discoverers 03/17/2004
New
Scientist reports that exquisitely-preserved butterflies have been
found in amber from the Dominican Republic. It was just
incredible, exclaimed a Smithsonian researcher.
Its no different than if you took a modern day butterfly and put it
under a light microscope. But this prompted a puzzle:
the amber is estimated to be up to 25 million years old.
Insects
were thought to have diverged from non-insects 40 to 50 million years
ago, but these Caribbean islands had to have drifted from the
mainland up to 50 million years ago, based on current theories of when
the islands separated from Mexico. It is unlikely that the
delicate butterflies could have crossed an ocean. These specimens,
therefore, must have already been present. If so, Butterflies
may be far more ancient creatures than previously believed, the
article states, and therefore, it is possible butterflies may have
even fluttered around the heads of dinosaurs, which were wiped out 65
million years ago.
Update 04/01/2004: Dick Vane-Wright puzzles
over this find in Nature April 1.1
Its discovery raises key issues, he says, about Caribbean biogeography,
behavioural evolution (or lack of it), and the origin of butterflies (emphasis
added in all quotes.) It looks like a living fossil. If so,
an implication is that the basic ecology of Voltinia has not
changed over this huge time span, (i.e., 15-35 million years,
an order of magnitude greater than the lifetime of the average species
[sic].
Vane-Wright is sensitive to a common fault among the brethren:
In evolutionary biology we must be alert to mere story-telling,
selecting suitable facts to support whatever view of events we favour,
he cautions; nevertheless, he feels compelled to accept the idea that no evolution
in this species occurred for tens of millions of years. Later, in discussing
favored views about when butterflies diverged, he quips, Here again we
have to beware of story-telling. He also borrows a joke from
a friend: As de Jong has wryly observed: We have no idea when
the butterflies originated, although there is no shortage of wild guesses.
1Dick Vane-Wright, Entomology: Butterflies at that awkward age,
Nature 428, 477 - 480 (01 April 2004); doi:10.1038/428477a.
This is a perfect time to review the correct procedure for reading a
science article. Always separate the data from the interpretation.
The data are five amber nuggets containing the best-preserved fossil
of any butterfly yet found. The species is almost identical
to its closest living relative on the Mexican mainland.
The dates, and the stories about
drifting islands and dinosaur wipeouts at such and such a time with
butterflies fluttering about their heads, is all interpretive fluff.
Brush it away like cobwebs. What remains? Butterflies
have always been butterflies. No transitional form was found.
No date came on the samples. No evolution was demonstrated
only beautiful design. Does this discovery provide
vital clues to the evolution of butterflies?
Does it explain why delicate butterflies, with wings like tissue paper,
survived whatever killed macho, muscular dinosaurs?
We report you decide.
Dick Vane-Wrights comments would almost make one think
that Creation-Evolution Headlines is having an impact. Scientists
seem more sensitive lately about the charge of just-so storytelling
(see also 04/01/2004 headline).

The Evolution of Cultural Diversity 03/17/2004
Darwinism can explain anything these days, including
everything from war
(see 09/16/2003 headline)
to the Golden Rule
(see 02/22/2004 headline),
so why not culture? All the arts, sciences, and languages are
candidates for naturalistic explanation this week. The self-proclaimed
successors of Adam Smith, Mark Pagel and Ruth Mace, put forward their
conjectures in The cultural wealth of nations in the
Mar.
18 issue of Nature.1 But first, this
reverie:
Humans are the virtuosos of cultural diversity. We fish, hunt,
shepherd, forage and cultivate. We practise polygyny, polyandry and
monogamy, pay bride-prices and dowries, and have patrilineal and matrilineal
wealth inheritance. We construct or inhabit all manner of shelters,
speak about 7,000 different languages and eat everything from seeds to
whales. And this is not counting many unique, and sometimes bizarre,
belief systems and behavioural practices.
(Emphasis added in all quotes.)
The mystery, in Darwinian terms, is how all this diversity could arise out of
a relatively uniform genetic code:
If the picture of human cultures is one of variability, the human genetic
landscape is one of homogeneity. All of humanity varies less genetically
than does a typical wild population of chimpanzees. This may
reflect our youthfulness as a species [sic]. Anatomically modern [sic] Homo
sapiens emerged [sic] only about 75,000–100,000 years ago [sic], and
may have suffered a demographic bottleneck in the recent past,
meaning [sic] that in evolutionary [sic] terms we are all descended from a
not-so-distant common ancestor. Also, of course, we can interbreed
throughout our entire worldwide range. Add the facts that we regularly
trade, migrate across each others territories and wage war against
each other, and a puzzle emerges: where does our extreme cultural
diversity come from, and what maintains it?
They suggest a new approach to solving this puzzle: think of human cultures
like diverse species, evolving by Darwinian means against each other:
The answers can perhaps be found in thinking about human cultures as if
they are collections of distinct biological species, they suggest.
Just as species carry genetic adaptations to their environments,
we believe that cultural adaptations have evolved in response to social life,
and that such adaptations work to maintain cultural identity and coherence.
Carrying the analogy further, cultural borders are like
cell membranes resistant to gene flow. They draw various analogies
between Darwinian biology and Darwinian cultural evolution, such as
phylogenetic trees of languages, the evolution of altruism, biogeography,
horizontal gene transfer, group selection, etc. Then they end on
what they term an unscientific postscript based on the
competing interests of the desire to control resources and the desire
to gain identity with a group
Putting these forces together, we get a picture of humans as a highly
social and group-focused species. None of this is to say that
selfish behaviour has been erased or that all cultures survive
intact. The all-too-common tragedies of the commons, in which
individual over-exploitation of common resources results in their collapse,
remind us of the price of selfishness. But this picture [sic] of the
nature of cultures suggests that they are surprisingly robust against outside
influences (although not invincible) and that, at least for large cultures,
worries about cultural swamping are overstated. Nevertheless, our
ancient cultural practices may also be telling us that, in a world in which
mass movements of people from poorer to richer areas will become ever more
common, we must be especially vigilant about our own tendencies to protect
the status quo ante.

We assume the authors were excepting themselves when mentioning
unique, and sometimes bizarre, belief systems.
These authors have just pulled the foundation of meaning out from under
all human communication, interaction, art, science and government,
but it doesnt seem to bother them at all.
Social Darwinism is still around, as you can see. Modern day
Marxists will feel warm fuzzies with this article. When scientists
omit the reality of intelligent design, all they have left is matter
in motion. That matter might be molecules, cells, or people,
but never life, liberty and the pursuit of happiness. It is
not self-evident truth to a Darwinist that humans are endowed by a Creator with
anything. Thus government, culture and language must all be just
artifacts of matter in motion. Human culture obeys the same Darwinian
laws as bacterial culture.
Left without design, their pet theory of evolution has to
fulfill the role of designer. Darwinians are always up to the challenge;
in fact, it is their form of entertainment
(see 02/22/2004 commentary).
The basic Darwinian plot provides an endless, malleable storytelling platform
for explaining anything
(see 01/15/2004 commentary),
and since the Starving Storytellers got on King Charlies welfare
programs and grew obese
(see 12/22/2003 commentary),
they no longer have any motivation for hard scientific work.
One outcome is predictable:
Nature, that megaphone for Darwin (see 03/04/2004
commentary), will be eagerly poised to shout the latest propaganda
to the masses.
Exercise Did you catch the admission that the entire human population
seems to have gone through a demographic bottleneck in the recent past?
And that we all might have descended from a not-so-distant common ancestor?
Can you a describe a historical event that fits this observation?
Extra credit: name the ancestor.

Neanderthals Not Our Cousins, Expert Claims 03/16/2004
The news media are reporting claims that Neanderthals and modern humans
never interbred, based on work from the Max Planck Institute for Evolutionary
Anthropology. Both EurekAlert
and Nature Science
Update repeat the claim that the institutes study of DNA and bones from four Neanderthals and
five modern humans from scattered locations rules out any interbreeding.
Thats until you read the fine print.
Can such things be known? Listen to the disclaimers in the NSU article:
Although the two groups seem to have been genetically separate,
the fossil record is too patchy, and dating methods too unreliable,
to say whether this was because they never met, or because they simply
didnt consider each other an enticing proposition.
Given the small number of fossils studied, its also possible
that interbreeding did occur, he [David Serre] adds, but that we have not
found the evidence yet.
Such a match-up would have been genetically feasible, says Stringer.
The two groups were closer in genetic terms than other primates that
happily breed today, he says.
(Emphasis added.) If these were potentially
interbreeding humans, then forget the racism going on in all this
Neanderthal/modern dichotomizing. All scientists can observe
is that there were a few distinct physical characteristics among the
Neanderthals, such as prominent brows and thicker bones. What can we
know but that early wrestlers and bikers just got together and formed their own
societies?
There are groups of modern humans even today who prefer to
associate with others like themselves. They can and do form distinctive
populations, like pygmies or Watusi. The Bible
speaks of the sons of Anak and the Nephelim who were giants in their
time. Did the Israelites interbreed with them? Probably not.
Was either group non-human? Of course not.
Dead men tell no tales. Living ones, however, often tell whoppers,
especially those in the Darwin population.

Privileged Planet Website Opens 03/16/2004
A website
featuring a new book by Guillermo Gonzalez and Jay Richards, The Privileged
Planet, has opened. The subtitle of the book is How Our Place
in the Cosmos Is Designed for Discovery. The authors take issue with
pessimistic views, such as those of Steven Weinberg and Carl Sagan, that our
planet is pointless or just a lost speck of cosmic dust
in the universe. Au contraire, the authors argue with many
interesting observations: our planet appears to have been intelligently
designed not only for our existence and well-being, but to maximize our
ability to comprehend the creation.
The website also highlights a documentary movie by the same
title due to be released soon by Illustra
Media, producer of the popular documentary Unlocking the Mystery of
Life. The film will feature Robert Jastrow, Paul Davies, Donald
Brownlee, and other prominent astronomers and philosophers. A video clip
of the opening is available on the website.
The book and film are being promoted by
the Discovery
Institute, an intelligent design think tank.
This is not a typical creationist book or film. To the extent it argues
that our universe and earth appear designed for life and discovery,
it makes an old anthropic argument stronger, adding an intriguing original
point that our position makes
science and discovery possible, as if that were the Creators intent.
Dont expect it to argue for a view of special creation by the
Judeo-Christian God, or to argue for a Biblical history or chronology.
It should, however, be a valuable resource to impel
knowledgeable skeptics to consider the evidence for design.
Dr. Gonzalez and Jay Richards have impeccable credentials and know their
specialties well.

Scientific Elitism Trumps Democracy 03/12/2004
They dont want it, but theyre going to get it. Britons
have expressed outrage and anger over genetically-modified foods, such
as pesticide-resistant maize, reports Jim Giles in
Nature.1 But the government has listened to scientists
who have assured government ministers it is safe. On March 9, they
approved commercial planting of GM maize in the face of widespread
public opposition. Giles says, In Britain, opposition to
agricultural biotechnology has been early and strident.
This decision may set a precedent: Both supporters and enemies believe
this weeks decision will influence debates outside Britain about
transgenic crops. How did such a decision get past the voters?
The case for the crops was boosted by a scientific review, released
last July, which found no reason to rule out carefully managed
cultivation of the plants. The review was discussed at a cabinet
meeting last month. Leaked minutes of the meeting state that
ministers acknowledged public opposition, but thought that
it might eventually be worn down by solid [sic], authoritative
[sic] scientific [sic] argument.
(Emphasis added in all quotes.)
Do the GM crops pose any danger of spreading outside the farm?
Farmers will also be wary of planting genetically modified varieties
before the government has clarified rules governing how they should be kept
separate from nearby conventional crops, the article states.
Regarding another ethical-political issue the use
of embryonic stem cells Science editor Donald Kennedy2
announced that South Koreas recent success in cloning a human embryo
makes this a good time for review of the ethics of the
procedure, which is currently banned from receiving federal funding in the United States
and Germany. Kennedy thinks the global scientific community should
be the arbiter of what makes a practice ethical. He writes,
Plainly, these findings may affect the U.S.
ethical debate. Leon Kass, the chairman of the Presidents
Council of Bioethics, sees them as a downward step on a slippery moral
slope: tomorrow, he predicts, cloned blastocysts
for baby-making. After the recent purge of two pro-stem cell
members, Kass has his commission under control. But science is,
after all, an international activity. The Korean success reminds
us that stem cell research, along with its therapeutic promise, is
under way in countries with various cultural and religious traditions.
Our domestic moral terrain is not readily exportable: U.S. politicians
cant make the rules for everyone, and they dont have a
special claim to the ethical high ground.
This seems to mean: others can do it, others are doing it, and who are
we (including the voters and democratically-elected representatives) to
stand in the way of science? Kennedy ends by quoting Harvard stem-cell
biologist Doug Melton: Look, life is short. I dont want
spend the rest of mine reading about exciting advances in my field that can
only be achieved in another country.

Volume 303, Number 5664, Issue of 12 Mar 2004, p. 1581.
They could do it; should they? Could
is technology; should is ethics. Not everything possible is
advisable. Scientists are involved in many activities that could
have profound societal effects: tampering with supergerms or nanobots
that, if released accidentally or by terrorists, might evade all our
defenses; producing chimeras, even combining human and non-human characters;
toying with human genes in ways that might
redefine what it means to be an individual. To whom are these
scientists accountable? Does wearing a white lab coat mean someone knows
the difference between could and should? Are scientists subject
to the rule of law as defined by duly-elected representatives?
Does the international scientific community comprise an elite oligarchy,
granted global powers that supersede the rights of voters?
What constitution gave them this authority?
The American founding fathers made government
accountable to the people. The purpose of government was to protect
individual, unalienable rights to life, liberty, and the pursuit of
happiness. These rights were to be secured through the ballot box
and due process of law. Elected representatives were to be entrusted with
decision-making power only with the consent of the governed.
Here, however, we see political and scientific
elitists making sweeping, dramatic decisions on risky practices riddled with huge
ethical concerns, just because they can, and they think they know what is good for us.
The point of this commentary is not to debate the specific
ethical dilemmas posed by GM crops or therapeutic cloning of embryonic
stem cells. It is not to get embroiled in the emotional arguments
about slippery slopes, countered by utopian promises of better health or
productivity. The point is that the decisions on these highly-charged
ethical issues are being made by elitists who have utter disdain for the
voice of the people.
Giles acknowledged the public outcry but seemed satisfied that if scientists
said its OK, then its OK, even though serious questions remain
unanswered about protecting the environment or human health.
The prior week in both Nature and Science,
editorials expressed outrage that the Bush administration had dismissed
Elizabeth Blackburn from the Presidents Council on Ethics, presumably
because she was so outspoken in her opposition to the administrations
position on stem cell research. The concern seemed to be more about
Big Science getting their consensus opinion represented on the council, not
whether an
elected representative had the right to select his advisors. And no
one was asking the obvious question, what do the voters feel about
stem cell research? How much voice and authority should an unelected
council of scientists have to tell the voters the difference between
could and should?
Kennedys editorial makes it clear he is much more interested in
could than should.
The bulk of his argument rests on pragmatism, if not utter selfishness.
Ethics, shmethics: Melton wants a piece of the action.
The Americans dont want the Koreans and other pinnacles of ethical
civilization to get all the Nobel prizes, whether or not such research leads to
designer baby-making down the road. Voters are idiots.
Scientists know what is good for them. (Now read the
03/04/2004 headline again.)

Much Ado About Nothing 03/12/2004
How much can you say about nothing? Some people can say quite a lot.
One astrobiologist just wrote a large book about it: Lonely Planets:
The Natural Philosophy of Alien Life by David Grinspoon
(Harper Collins, 2003).
Larry R. Nittler reviewed this new book in the
March 12
issue of Science.1 Nittler describes how interest
in alien life fell into the scientific sub-basements of
exobiology and radio searches for extraterrestrial intelligence
(SETI) after pictures of Mars in 1965 revealed disappointing
deserts of lifelessness. But thirty years later,
three developments led to a resurgence of interest in alien life:
(1) the discovery
of extrasolar planets (see 07/21/2003
headline), (2) evidence for probable oceans under the ice of
Europa (see 02/11/2002 headline),
and (3) claims of fossil bacteria in a Martian meteorite
(see 03/18/2002 and
05/15/2002 headlines).
NASA launched its Astrobiology Institute in 1998
(see 08/23/2001 headline),
imbuing new respectability into the study of alien life.
Nittler explains, however, why astrobiology
is essentially the science of nothing:
Given the current surge in scientific attention to alien life, it is easy
to think that recent developments constitute a revolution of
sorts. However, our actual knowledge of alien life
remains the same as it has been for centuries and can be summarized
by a single word: nothing. Nonetheless, in Lonely Planets
David Grinspoon provides a masterful [sic] synthesis of the history, science,
philosophy, and even theological implications of extraterrestrial life.
(Emphasis added in all quotes.)
So what can be said about nothing to fill 460 pages? Grinspoon divided
the nothingness into three sections: history, science, and belief.
In the history section, he examined beliefs about alien life from
Kepler
to the present. Nittlers review points out that pessimism about
alien life has been rare. Up until the 1960s, for instance,
most people believed the dark patches on Mars were signs of vegetation.
In the science section, Grinspoon weaves a tale of
cosmic evolution from the Big Bang through the formation of the solar
system and the evolution of life on Earth, Nittler says
(see 07/15/2002 headline for more on
Grinspoons beliefs).
The author strenuously argues against the Rare Earth
hypothesis of Peter Ward and Robert Brownlee (see
12/19/2000 and
01/14/2003 headlines), preferring to trust
in the adaptability of life to different environments and especially
the role life has played in shaping Earths unusual characteristics.
As to this role, and its meaning for the definition of life,
Grinspoon uses the Gaia hypothesis (that Earth can in some sense be
considered a super-organism of interconnected biogeochemical
feedback mechanisms) and complexity theory to argue for a more
generous definition of habitable worlds. He holds that a key
characteristic of living worlds [sic] should be chemical
disequilibrium, with large flows of energy and/or matter. By these
criteria [sic], he suggests, we should [sic] also be searching for cloud
creatures [sic] on Venus and sulfur-based critters [sic] on the
volcanic Jovian moon Io.
(For more on Gaia, see 12/18/2003
headline.)
The third section of the book deals with beliefs about aliens, from
UFOs to SETI to politics. There is the ubiquitous Drake equation,
speculation about the future of human evolution, and much more.
Given that most evolutionists dismiss claims of UFO abductions and conspiracy
theories, Grinspoon is surprisingly open-minded about the nothing we
know. But the reviewer detects a little hypocrisy:
His emphasis continues to be on keeping an open [sic] mind. SETI
assumes that aliens would continuously broadcast radio transmissions for
thousands of years. Anti-UFO skeptics argue that UFOs are not alien
spacecraft, because aliens just wouldnt act that way.
But both assumptions are based on preconceived notions of alien
behavior [sic], about which we actually know nothing. (Grinspoon
falls into his own trap as well, dismissing popular ideas about UFOs
basically because they are so B-movie.)
Grinspoon doesnt think humans are intelligent yet. He seems
to measure intelligence in global terms, and so does Nittler. Here is
where politics enters the discussion about nothing, where it is difficult
for either of them to know where rational discussion ends and
wild speculation begins:
The book becomes increasingly personal in the final chapters as Grinspoon
delves deeper into more speculative ideas regarding spirituality
and the nature of intelligence. He muses that humans are not yet
truly intelligent and that to become so will require much better
collective behavior as a species. He seems overly pessimistic
in his assessment of our likelihood of becoming such a species, based
on our propensity for perpetrating violence on one another.
I would argue that such developments as the global eradication of certain
diseases and the advent of international courts to try war criminals
paint a more optimistic [sic] picture than the examples he gives of
SETI@home and world music. The author closes with even wilder
speculation regarding species immortality and machine civilizations
[sic].
Nittler sees the author as a product of the 70s, considering Isaac Asimov
and Carl Sagan were family friends of the Grinspoons.
This background clearly colors his thinking about his subject,
Nittler says, and his optimism about the existence of alien life
sometimes comes off as wishful thinking informed by too many Star Trek
episodes. But overall, he compliments the book for its
writing style, and the fact that Grinspoon tries to be clear about where
the science leaves off and the
intellectually squishy natural philosophy begins.
In the end, Nittler concludes on a happy note, Lonely
Planets is an entertaining and thought-provoking [sic] book about
a great deal more than nothing.

Looking for Life in Far Distant Places,
Science
Volume 303, Number 5664, Issue of 12 Mar 2004, p. 1614.
We didnt say the book was about
nothing: he did. We didnt say the book contained wild
speculation: he did. We didnt say the author was selectively
open-minded: he did. We didnt call it a tale of
cosmic evolution: he did. We didnt use the phrases
intellectually squishy and wishful thinking to
describe Grinspoons ideas: he did. Cloud creatures on Venus,
sulfur critters on volcanic Io, machine civilizations, international courts as
a measure of intelligence... good grief.
Yet Nittler calls this
book a masterful synthesis of ideas on well, nothing.
That makes Nittler a co-conspirator, an accessory to the crime of allowing
stupid ideas to get good press in Americas premiere science journal.
If a creationist made claims on this level, they wouldnt get past the
National Enquirer. The code of silence in the Darwin Party requires
that none of the brethren are to be publicly humiliated. Even if lightly
tapped with padded gloves, they must be praised as defenders of the
tale of cosmic evolution.
Dont be fooled by the
talk about spirituality and theological implications
of finding alien life. We know what they mean, and its not
asking what must I do to be
saved?
(see 03/11/2004 headline).
Both men unfairly attack Kepler (see our
online biography). Nittler lets him
get away with libel: Grinspoon reminds [sic] us
that Johannes Kepler was [sic] a philosopher/freak who walked
the fine line between genius and delusion. Speak for
yourselves. Both of you would do well to read the life and writings
of the father of planetary science, and learn to respect his integrity
and intelligence. His wildest speculations were
tame compared to these.

Major Cave with Fossils Found in Arizona 03/11/2004
Arizona
Central has announced a major cave discovery east of Tucson.
The cave, named La Tetera, was discovered eight years ago but was kept
secret till today. The first human exploration only began New Years
Day 2002. The cave, located within Colossal Cave State
Park, is said to rival or exceed Kartchner Caverns in the size and beauty
of its formations. One large chamber has a floor covered in delicate
crystal, with huge multicolored domes reaching to the ceiling.
State officials intend to keep the cavern available to
scientists
only; it will probably never be open to the public.
Much of the cave still remains to be explored; about 2000
feet of passageways have been mapped so far. It appears in pristine
condition, moist and growing in fact, vapor rising from an orifice
gave it the name La Tetera, Spanish for teakettle.
Unlike Kartchner, La Tetera Cave contains many bones of
animals said to have gone extinct 10,000 years ago, including
prehistoric horses, camels, rattlesnakes and other animals.
The article states, Experts estimate that La Tetera is about 10
million years old - compared with less than 1 million years of age for
Kartchner.
Discoveries like this make exciting news. Only the underground
environment provides opportunities for 21st century explorers to discover
virgin territory. Click the photo gallery link in the article
to view beautiful pictures of the interior of this cave.
What other magnificent caves on this vast
planet remain to be discovered?
What is uncalled for in such reports is the obligatory reference to millions
of years. If you read the scientific report on nearby Kartchner
Caverns (available in the bookstore), you find that the dating methods are
compromises of conflicting measurements based on prior assumptions.
Think about it;
if there had been 9,990,000 years available for animals to stumble into this
cave, wouldnt it be totally filled with bones?
The long ages that tour guides and reports typically
spout are usually stated in a glib, matter-of-fact way, without
revealing the many assumptions that go into the estimates, or the many
evidences around the world that contradict the dates.
Ball park figures for cave dates are usually established
beforehand from uniformitarian and Darwinian assumptions, so that they fit
into the evolution-based geologic column (but see the
03/05/2004 headline).
Furthermore, the dating methods commit the fallacy of
extrapolation of current processes
far beyond what is justifiable. Check out the following three articles, two by Ph.D.
geologists, that explain how cave and speleothem formation do not require such
vast periods of time: Snelling,
Oard,
and Austin.
Next time on a cave tour, politely ask the guide how he or she knows the cave
is x million years old. Unless trained in anti-creationist tactics,
the guide will usually stutter and stammer, admitting that he/she is just repeating what
the script says. Then, for fun, show the guide
this
picture.
Here is a great new DVD to expand your mind about cave formation
and geology in general, by a world-class caver and PhD geologist, Dr. Emil
Silvestru:
Geology
and Cave Formation. It contains stunning photographs and just as
stunning facts, by someone who knows caves better inside and out than most
people. Just as good is another DVD by Dr. Silvestru entitled,

The Evolution of Omnipotence
03/11/2004
With a headline like New Theory: Universe Created by
Intelligent Being, one might think that
National
Geographic News has gone creationist and rediscovered Genesis 1.
The opposite would be true. The article by John Roach explores the
radical thinking of a lawyer/scientist named James Gardner, who has just
published a book, Biocosm: The New Scientific Theory of Evolution:
Intelligent Life Is the Architect of the Universe. It is the
ultimate statement, not of creation, but of evolution.
Basically, Gardner believes that intelligent life inevitably evolves to the point
of being omnipotent, at which time it will learn how to create a new universe.
He calls intelligent life the reproductive organ of the cosmos.
Intelligence gets passed on to the next universe like a DNA code, ensuring
the daughter universe is fine-tuned for life. This explains the
Anthropic Principle (see 02/28/04
headline), the observation that our universe is life-friendly.
As to ultimate origins, he postulates a closed time-like curve wherein
the universe serves as its own mother.
But the all-powerful, intelligent creator Gardner imagines
was no benevolent, self-existent Person, Someone who might love His creatures
enough to become incarnate with them
and die for their sins.
On the contrary; Gardners creator is selfish. He calls
his cosmology the selfish biocosm theory, an extension to the
nth degree of Dawkins selfish gene concept that
there are entities that use organisms for their own propagation.
Gardner makes it clear his inspiration was Charles Darwin.
