Naturalism Extends Into All Realms of Scholarship 04/30/2007

Defenders of evolutionary theory typically argue that their ideas are merely scientific
approaches to explaining biological objects. Why, then, are evolutionary approaches extended to
intangible realms, like psychology, ethics, criminal law, politics, religion, character and morals?
Here are some recent examples to think about:
- Evolution and the Criminal Mind: In a paper this month in the
Public
Library of Science: Biology, four evolutionists gave naturalistic views on
Law, Responsibility, and the Brain. They said we need to examine
the violent behavior of our alleged hominid ancestors to understand the criminal mind.
They also asked, Should we rethink free will? One would think such subjects
belong to the realms of moral philosophy and theology. While they agreed that
Violent and anti-social behaviours undoubtedly arise from a symphony of factors,
they admitted only naturalistic approaches: Optimal understanding will require cooperation
among many disciplines such as economics, sociology, psychology, evolutionary biology,
cellular physiology, and neuroscience. Preachers and philosophers apparently
do not have any opinion worth thinking aboutif, indeed, thinking is even possible
in a world reduced to particles.
- Matter over Mind: In an essay in the same issue of
PLoS
Biology, Kevin J. Mitchell (Trinity College, Dublin) got physical in his essay,
The Genetics of Brain Wiring: From Molecule to Mind.
That his conception of mind did not extend beyond the material world is
clear in his conclusion, Putting It All Together
The challenge for the fields of neurodevelopmental and psychiatric genetics is to develop
methods to take these factors into account in attempting to map from genotype to
anatomical and physiological phenotypes and beyond to behaviour and cognition.
Modelling this complexity may require both new mathematical methods and more detailed
empirical data derived from studies of model organisms. Whichever approaches are taken,
it is clear that to understand the origins of individual differences in psychological traits
we must keep developmental trajectories, and not just phenotypic end points, in mind.
Yet one might ask, is there a mind in which to keep such abstractions?
- Language: The ability to speak in abstract terms using
verbal constructs is no longer a human distinctive. In the evolutionary view, its only a
matter of degree. A duo from Emory University studied chimpanzee gestures for clues to a
natural story of language. Publishing in
PNAS, they began and ended
with Darwinian explanations:
The natural communication of apes may hold clues about language origins, especially because apes
frequently gesture with limbs and hands, a mode of communication thought to have been the starting point of
human language evolution. Popular news sources, like
Live Science and
MSNBC,
quickly featured this speculation as a scientific finding. Ker Than titled the story,
Apes Point to Origins of Human Language. It came complete with photo of a gesturing
chimp. No alternative viewpoints that would question naturalism were considered.
- Natural Politics: Not even political science is exempt from the naturalistic approach
to the world. Two Princeton economists writing in
PNAS discussed
Political Polarization with a Bayesian (i.e., mathematical) model of how groups
tend to polarize on issues. The content of the debates and the weight of arguments were not
elements in the equation: We offer an explanation of
such polarization, based on a natural bimodality of preferences in
political and economic contexts and consistent with Bayesian rationality.
The paper is full of calculus and graphs and models that predict degrees of polarization based
on bimodal inputs. What kind of political issues fall under the spell of their equations? Current examples are
policies concerning discrimination, immigration, gender, religion, welfare state, human rights,
terrorism, civil wars, national sovereignty, and nuclear armament.
Though this last paper is not overtly Darwinian, and does employ concepts of the subjects
world view and opinions, it treats human subjects as mathematical objects that follow natural
laws. The degree of detail with which the authors manipulated human subjects as elements of differential equations
is striking. It raises profound questions about the extent to which such domains fall within natural
science: e.g., are populations of rational agents determined by natural law, and if so, are they really
rational agents? And one would be hard pressed to imagine these scientists giving a naturalistic answer to this question:
On what basis are you assuming that reduction of polarization is a good thing?
If their model is valid, it should be possible to debate that question and plug its variables right back into the equation to arrive
at a degree of polarization, then iterate the process ad infinitum to the vanishing point of the
point: i.e., ultimate pointlessness.
No one asks the questions that deflate these naturalistic studies and
make them shoot their own feet. Each one of these studies is self-refuting
and thereby pointless. If responsibility is an evolutionary by-product, it is not really responsibility.
If crime is an evolutionary by-product, it is not really crime. If language is glorified ape gesturing,
it is not really language. And if voters are pawns of mathematical functions, they are not really
informed, thoughtful voters.
Overarching above all these conundrums is the meta-conundrum that pulls down the curtain
on the whole charade: each of these scientists, according to their own presuppositions, is also a pawn of
evolutionary forces. Nothing they say, therefore, has any validity. If they are thinking
they need to rethink free will, they are not really thinking! They are not free to think.
Their own thoughts are determined by their evolutionary past. This is so obvious, why doesnt
anyone ever call their bluff? On their own assumptions, you can dismiss everything they said.
There is nothing stopping a trickster from turning these same tactics against them.
Lets say, for instance, that David Horowitz were to hire a skilled mathematician to construct a mathematical
model of liberalism in academia. A conservative sociologist could play the game, too.
They could produce an impressive-looking paper, loaded with graphs and
equations, showing the tendency for academics to slide into liberalism as a function of time and peer
pressure. They could even formulate a new natural law: the second law of intellectual thermodynamics.
If they had enough connections to get this published in a major journal, would it not make as much sense as
the paper on political polarization?
What on earth is a paper on poli-sci doing in the Proceedings
of the National Academy of Sciences? What are biologists doing trying to reduce responsibility
and the mind and religion to molecular interactions? Even if their models occasionally correspond with
observations, that would
not ipso facto validate them. The cliche fits: even a broken clock can be right twice a day.
There are things about intelligent agents and their behaviors that science cannot address with laws
and equations. You cant treat human beings like lab rats (the ratomorphic
fallacy). And we cannot let pointy-headed academics with a bad case of the Yoda Complex
(03/21/2007, 09/25/2006)
get away with folly in the name of science, using their minds to claim that minds dont exist.
When a materialist makes material claims, ask them those four little words, How do you know?
If the mind is the result of contingent or determined natural processes, then so are any thoughts about it.
This undermines any truth claimsincluding those of these papers. We must not permit the
evolutionists to stand outside their heads, looking down on the rest of us, telling us how WE evolved.
They must get into the game. But a little reflection shows why they cannot do that. When
they enter the game, the game is over. Without an Umpire, without rules, without standards, without
truth, and without morals, its not a game. Its chaos.

Snot Serious: Artificial Nose Works Better with Mucus 04/30/2007

What will they think of next? Designers of electronic noses cannot yet come close
to the natural nose in sensitivity. But in trying to improve their devices, they tried
another trick from nature: artificial boogers. Yes, believe it or snot, adding a layer of
synthetic mucus improved the performance of their electronic nose allowing it to tell
apart smells such as milk and banana which had previously been challenging smells for the device.
So reported University
of Warwick in all seriousness.
Science Daily also had a nose
for the news.
Why did this work? In the natural nose, a mucus layer entraps incoming particles. This
dissolves scents and separates out different odour molecules in a way they arrive at the
noses receptors at different speeds/times, the press release says. Humans are then
able to use this information on the differences in time taken to reach different nose
receptors to pick apart a diverse range of smells. The electronic nose has only
50 receptors, compared to a humans 100 million specialised receptors or sensors
which act together in complex ways to identify and tell apart the molecules they encounter.
Thats not something to sneeze at.
You probably had no idea that mucus had that function.
You knew that it conveys dust and particles out of the nasal passage and helps keep those sensitive
linings moist, but did you realize it actually enhances your sense of smell? Amazing.
Think of all the information you toss out with each tissue.
Now they need to figure out how to blow an electronic nose. (Do NOT use the electronic finger.)

Swifts Dont Just Dream of Flying... 04/29/2007

...they fly while dreaming. Did you know that swifts, the aerial acrobats of the air,
sleep on the wing? Thats not all, they adapt their wing shape to turn on a dime.
Science Daily
summarized the cover story of Nature this week (April 26) that examined wing
morphing in swifts their ability to change wing shape in flight. Dutch and Swedish scientists ran tests in
wind tunnels to measure the lift and drag for different wing shapes. Extended wings are
more efficient for gliding, but swept wings are good for tight turns and
speed. Swept wings also protect against breakage. Swifts gain a 3-fold advantage in
flight efficiency by continually adjusting the shape of their wings.
Wing morphing is the latest trend in aviation, the article says.
NASA is experimenting with micro-aircraft that can vary wing shape in flight for use in surveillance.
Students in the Netherlands are also imitating the flight of the swift with their model aircraft.
But then, even the Wright brothers observed birds for ideas on how to construct wings for the first airplane.
The article also says that swifts even mate in the air. They only land on their cliff-hanging
nests to lay eggs. Otherwise, its in the air all the timeup to 1.5 km high at
night while roosting in mid-air. European swifts migrate to South Africa and back each year.
In a lifetime, a swift will fly 4.5 million kilometersequivalent
to 100 round trips around the Earth.
Swifts also eat up to 20,000 insects a night. Fortunately, no
evolution fables polluted this story. No one tried to say that a T. rex morphed into a
swift over millions of years. That wouldnt fly on a wing or a prayer.
Who taught swifts the kind of aerodynamics NASA admires? Who gave them both the hardware and
software to live on the wing almost all the time? Who programmed the autopilot that allows them
to roost without a roost? Calling a swift swift is like
calling an orange orange. What would they call a human? Smart? Wise? Sometimes.
Homo is not always sapiens sapiens. For proof, see next entry.

Stupid Evolution Quote Prizes 04/27/2007

The Stupid Evolution Quote of the Week goes to Mark Gladwin
(04/25/2007) who said something the gentler
sex will probably wince at:
Study the pregnant women, because thats where youll see evolution in action.
No offense intended, we hope. A runner-up goes to Deborah Charlesworth, who in
Current Biology
April 17 named Darwin as a scientific hero and
associated Darwin-doubters with militant ducks. Asked
what is the biggest current challenge facing the scientific community, she said,
I think it is the difficulty of communicating an understanding of what science really is.
This is affecting young people who dont feel the fascination of science, and it is allowing the
spread of all kinds of irrational beliefs, such as quack medicine. Evolutionary biology
is under repeated attack from those who think, or wish, that non-natural processes
must be involved.
Another contestant was Charles Lineweaver in
Astrobiology Magazine who, in reviewing a book about the Gaia hypothesis,
swept away Darwin-doubters with one hand while scratching his head over a fundamental Darwinian question with the other hand:
Forget the debates with creationists and intelligent designers; the scientific debate about the unit of
selection is one of the most important challenges that Darwinism has ever had to face.
A new prize for Stupid Evolution Quote of the Month should probably be instituted for
contestants like the following. David Brooks, a conservative columnist for the New York Times,
wrote in an editorial entitled The Age of Darwin that evolution has become the
unifying grand narrative of the modern age. Writing from Jerusalem, where he
compared the holy sites to the Rockefeller Museum, he wrote in superlatives that would make Darwin blush:
And it occurred to me that while we postmoderns say we detest all-explaining narratives, in fact a
newish grand narrative has crept upon us willy-nilly and is now all around. Once the Bible shaped all
conversation, then Marx, then Freud, but today Darwin is everywhere....
According to this view, human beings, like all other creatures, are machines for passing
along genetic code. We are driven primarily by a desire to perpetuate ourselves and our species....
The cosmologies of the societies represented in the Rockefeller Museum looked up toward the
transcendent. Their descendants still fight over sacred spots like the Holy of Holies a short walk
away. But the evolutionary society is built low to the ground. God may exist and may have set
the process in motion, but hes not active. Evolution doesnt really lead to anything outside
itself. Individuals are predisposed not by innate sinfulness or virtue, but by the epigenetic rules
encoded in their cells.
He ended, We have a grand narrative that explains behavior and gives shape to history.
We have a central cosmology to embrace, argue with or unconsciously submit to.
This editorial by David Brooks (read it in its entirety at
Free Democracy)
brought sharp rebukes from Richard Kirk at
The American Spectator and
Bruce Chapman at the
Discovery Institute.
Kirk accused Brooks of personification in his depiction of the logic
of evolution: One must slip a personifying image of Mother Nature through an intellectual back door to make
the term mean what Brooks implies in his paean-of-sorts to Richard Dawkins Blind Watchmaker.
But the bluntness of the wording in the editorial led some to believe that surely Brooks was satirizing Darwin.
Thats what Logan Gage at Discovery
Institute first thought, but now hes not sure. Maybe our readers can tell if it was
all just a joke.
Update 04/28/2007: The verdict is in. Logan Gage wrote again for
Evolution News that
despite his incredulity Brooks would say such things, he stands corrected: Brooks would, and did.
For the sake of Mr. Brooks reputation, we certainly wish he had been
joking. A worse statement of utter capitulation to Darwin could hardly be found. It is totally groundless,
self refuting, simplistic
and uninformed if he meant it seriously.
Current Biology, true to form, dredged up another Darwin lover for its biweekly
interview. The answer to the obligatory question Do you have any scientific heroes? must
include Darwin or else you get dunked. Its all a game the editors play.
Deborah Charlesworth, like her husband Brian, are card-carrying members of the Darwin Party attack force.
This means they have to portray the peace-loving Visigoths as the attackers. At least she also included
Gregor Mendel as a scientific hero.
Charles Lineweaver showed the childlike faith in Darwin, characteristic of good disciples,
that can permit the most damning questions to remain unanswered while ignoring those who have a different approach.
Oddly, he can give the time of day to weird science like Gaia, but not offer one short sentence to the kind of theistic
science that built modern science in the first place (online book).
Its quotes like these that lead one to resign oneself to the strategy of Max Planck who, when
asked why quantum mechanics became accepted, remarked that the doubters simply died off. Sad to say,
a younger generation of more open-minded scientists willing to consider design arguments will likely have to tolerate
the rantings of Darwins old fogies (like certain Senators) for a few more years.

Update on Plant Communication 04/26/2007

Plants have both an intranet and an extranet. Some recent papers investigated further about how plants, though
rooted in the ground, keep in touch with the inside and outside economy.
- Intranet: In 2001 (07/13/2001), and periodically since
(10/04/2004, 11/09/2004)
we reported the current thinking about
how a plant knows when to flower, and described a kind of email system the plant uses to keep
in touch with itself. Scientists have been hot
on the trail of the mysterious florigen (whatever it is) that travels through the vessels
to the growing tip and turns on the flowering process. They have known since 1865 that something
travels from a sunlit leaf to the apical meristem where flowers are produced. Now, according to
both Science April 20 and
Nature
April 26, they think the packet is not the messenger RNA from the FT gene, as previously
announced (08/12/2005), but the protein it
encodes. Understanding what the protein does upon receipt is an obvious
next step. Then, what in a leaf triggers the email to be sent? And is the packet sent throughout the
entire plant? For now, the botanist hackers are just trying to get good at sniffing the internet to
find the packets, let alone decode the payload.
Down below, at the root level, what happens? A European team reporting in
Current Biology thinks they have unmasked
the signals that turn on (or off) root cell differentiation: Analysis of the root meristems of
cytokinin mutants, spatial cytokinin depletion, and exogenous cytokinin application indicates that
cytokinins act in a restricted region of the root meristem, where they antagonize a non-cell-autonomous
cell-division signal, and we provide evidence that this signal is auxin.
- Extranet; When plants need to talk to their neighbors through their own kind of VPN
(virtual plant network, our joke), they waft volatile compounds into the air. Some of these
compounds are chiral they come in left- and right-handed forms. Scientists are just at the
leading edge of understanding what these compounds are and what they do. A news item in
Nature
described the work of a team that flew a Lear Jet over the forest canopy to gather some of the compounds.
A sophisticated survey of certain volatile organic compounds in the air over forest ecosystems shows
how such work can reveal varied emission patterns of different chiral, or mirror-image, forms of these compounds.
Plants emit more volatiles than animals by orders of magnitude, the article states. Some compounds
can repel insect pests, while others can attract pollinators. This article described how the plant
can send out different chiral forms of the same molecule for different purposes. Some, for instance,
appear to be temperature dependent, while others are light dependent. Volatile organic compounds
have a fundamental role in the coexistence of the flora and fauna in ecosystems, the article explains,
But there is still much to learn about the relationships and interactions between species that can
be related to an effect of naturally produced compounds such as monoterpenes. The compounds
may vary by species, by individual plant, and even by tissues within the plant. The scientists are
comparing forest emissions from South America, Suriname and Finland.
The trees may not talk like the Ents in Lord of the Rings, but they do have a language
that humans are just beginning to translate.
Dont talk to your plants unless you learn the language. Suggested learning tool:
a Lear Jet.

Human Adaptation Can Be Rapid 04/25/2007

How long does it take for humans to adapt to environmental changes? Some recent papers
investigated this question.
- Paleface: If it is assumed that humans started out medium or dark-skinned, how
long did it take for Europeans to lose much of that original pigment? An article in
Science April 20 says
maybe just 6,000 to 12,000 years. This contradicts a long-standing hypothesis that
modern humans in Europe grew paler about 40,000 years ago, as soon as they migrated into northern
latitudes, the article states, reporting on a March meeting of the American Association of
Physical Anthropologists. Pale skin is said to have an adaptive value at high latitudes: Under darker skies,
pale skin absorbs more sunlight than dark skin, allowing ultraviolet rays to produce more vitamin D
for bone growth and calcium absorption. The new date was based on genetic studies that suggested
a selective sweep occurred 5300 to 6000 years ago or up to 12,000 years ago, given
the imprecision of method.
- High life: Ann Gibbons in Science
reported on another discussion item from the American Association of Physical Anthropologists: how Tibetan
children can tolerate the high altitude. Researchers seldom see Darwinian natural selection
happening in living people, she began. So physical anthropologist Cynthia Beall was
delighted in 2004 when she discovered a trait that boosts the survival of some Tibetan children,
apparently by raising the level of oxygen in their mothers tissues--a crucial advantage during
pregnancy 4 kilometers above sea level. Updated research has revealed a genetic change that
allows women to boost their blood volume and deliver more oxygen to the tissues. Beall measured
the selective pressure at 1:0.44, stronger than the fitness ratio measured for the sickle-cell gene.
They said, the adaptation represents some of the strongest natural selection yet measured in humans.
Surprisingly, this appears to be a different adaptation mechanism than that found in populations
living in the Andes. There, mothers are able to boost the amount of hemoglobin. These correlations
are uncertain, however; its quite possible that the Tibetans have evolved more than one way to boost
blood oxygen, Beall cautioned. Mark Gladwin threw in a Darwinian proverb:
Study the pregnant women, because thats where youll see evolution in action.
- Got milk? Another strong selection effect in humans is for lactose tolerance.
Current Biology (April 17) had an article on this
phenomenon, which might have meant the difference between life and death to early dairy farmers,
Greg Gibson (North Carolina State U) said. The admittedly imperfect ability to tolerate lactose
represents another selective sweep some 5,000 to 10,000 years ago, about the time humans began to domesticate
cattle. He remarked, It is hard to refute that this is a lovely example of the
coevolution of genes and culture.
Nevertheless, Gibson spent most of the article debunking the thrifty genes hypothesis of evolutionary
selection. This is a 45-year-old idea that the high incidence of diabetes in modern humans is a
result of positive selection for alleles that confer the ability to rapidly sequester rare caches of carbohydrates
as fat that would tide us over during famine. This adaptation now works against us in our urbanized
society, it is claimed: it tends us toward obesity. So why does Gibson think this is a poor hypothesis?
Unfortunately, these three preconditions for natural selection are all too often mistaken by adaptationists as both necessary and sufficient for evolution to occur, he cautioned.
But we need to be more quantitative if sufficiency is to be proven. At the end, he was
even more emphatic: Those inclined toward Darwinian medicine like to explain disease as the
price we pay for the beneficial effects of alleles that have accompanied human adaptation.
These cases of not-so-thrifty genes suggest though that we should not be so quick to jump on the
bandwagon:
the coevolution of genes and culture is tremendously more complex.
Funny he should mention Darwinian medicine. A paper on that very subject appeared in
Public Library of Science: Biology this month.
Catriona J. MacCallum tried again to make the case that medical doctors need to study evolution to understand
disease (cf. 01/13/2003. Distressed that medical schools are not
considering evolution essential to the curriculum (see 06/25/2003), MacCallum
wrote,
It is curious that Charles Darwin, perhaps medicines most famous dropout, provided the impetus
for a subject that figures so rarely in medical education. Indeed, even the iconic textbook
example of evolutionantibiotic resistanceis rarely described as evolution in
relevant papers published in medical journals. Despite potentially valid reasons for this oversight
(e.g., that authors of papers in medical journals would regard the term as too general), it propagates into
the popular press when those papers are reported on, feeding the wider perception of evolutions
irrelevance in general, and to medicine in particular. Yet an understanding of how natural selection
shapes vulnerability to disease can provide fundamental insights into medicine and health and is no less
relevant than an understanding of physiology or biochemistry.
MacCallum agreed that the thrifty gene concept has fallen into disfavor. Some other evolutionary
ideas are also simplistic: The relationship between changing environment, diet, and susceptibility to disease,
however, is also far from clear. Attempts to recreate a Stone-Age Diet can be misleading, she
said. Still, she promoted the idea that evolutionary concepts can help medical practice. Granted, a mechanic may not
need to understand the history of technology to fix a car, but an understanding of the evolutionary principles can
help prepare for outbreaks of infectious disease, like bird flu, she argued.
Why the resistance to evolutionary teaching in medical schools? In some cases, its the
students who rebel:
Although Paul OHiggins thought a comparison of the brachial plexus to the pentadactyl limb was
helpful, not all his students agreedcomplaints were lodged that he was forcing evolution on them.
That lack of support was also reflected in the participation of only three medical students at the York
meeting (albeit enthusiastic ones), despite being widely publicized. It is not clear whether this
is because medical students are more overburdened than most or because of a more deep-rooted resistance
to the subject, reflecting wider political and religious prejudice against evolution.
So whats the solution? But evolutionary medicine isnt and shouldnt be controversial,
and the best way to challenge prejudice is through education. She took refuge in the famous Dobzhansky
quote, Nothing in biology makes sense except in the light of evolution. As an experiment, lets
consider the three cases listed above. It isnt very controversial that survivors of lactose, decreased
sunlight and oxygen will predominate in those environments, but arent they all still human? Is this
really the kind of evolution that Darwin meant?
MacCallum was undaunted by such questions. The time has clearly come for medicine
to explicitly integrate evolutionary biology into its theoretical and practical underpinnings,
she ended with rhetorical flair. The medical students of Charles Darwins day did not have
the advantage of such a powerful framework to inform their thinking; we shouldnt
deprive todays budding medical talent of the potential insights to be gained at the
intersection of these two great disciplines. Convincing the medical students of this may be the hard part.
You do NOT want an evolutionary biologist in the room when you need TLC at the
hospital. Lying in bed with pain and weakness, you are not going to look like a fit individual who deserves to
survive.
MacCallum again exhibited the shallowness and uselessness of evolutionary thinking. Notice
also the elitist snobbery: anyone who doesnt agree with the Darwin Party Framework is prejudiced by
definition, and must be sent to the re-education camp (cf. 12/21/2005).
Despite the pleas to pul-lease teach Darwin in medical school, medicine is doing fine without the
help of Dropout Darwin. Medicine has a multi-thousand year history that was advanced largely by Christians. The examples
she cited, including the iconic textbook example of evolution antibiotic resistance (dealt a blow by Jonathan
Wells in his book Icons of Evolution; see also the Darwinist confession from 09/12/2004)
are all just microevolutionary changes. The three examples reported
above are all microevolutionary changes. Natural selection at the micro level is not the issue. Even
young-earth creationists accept that.
Such evidence has nothing to do with Darwins colossal simplistic
generality, the Mystical Tree of Life
(02/01/2007). It has nothing to do with proving that
humans have bacteria ancestors,
and most medical students and professors know it. You can almost hear the snickers of students in the
classroom when the Prof tells his little fable about how the brachial plexus resembles the pentadactyl limb.
Right, Teach. Will that be on the test? Can I take a pill and call you in the morning?
Maybe the only way to get a higher turnout than three students at
the next well-publicized Medicine and Evolution meeting is to award extra credit, provided the students
are allowed to bring cots and pillows.
Despite the Dobzhansky rallying cry, things make perfect sense without evolution. In none of the
three cases listed above is Darwin vindicated or needed. All the humans in those societies are still one species
with the rest of humanity, capable of
intermarrying and raising children. Whats more, the adaptive changes observed did not take hundreds
of thousands of years. To the consternation of earlier Darwinists whose ideas are now discredited,
the changes fit easily within a Biblical framework of human history. What is Darwins score? Even
MacCallum admits that previous evolutionary ideas like thrifty genes have been discarded. Is anything
left that is not controversial and subject to overthrow? We dont need Darwin. We dont want
Darwin. We want to make sense in the light of the evidence, and help the weak in the process.

Time for Mammals 04/25/2007

Three recent news stories about mammals involve time. Does nature time things well,
or do evolutionists tell swell things about time? Time will tell.
- Placental mammals Watch those assumptions: How much can you trust
dates that can vary by 50%? A report in Science
Daily says the new consensus date for the appearance of placental mammals just jumped from 122 million
years ago to 84 million years ago. The article mentions assumptions three times, though, with
serious caveats about those dates: However, this discrepancy may not be real, but rather appear
because of the violation of implicit assumptions in the estimation procedures, such as abrupt
acceleration of evolutionary rate entangled with gradual variation and large-scale convergent evolution in
molecular level. Later, They emphasize the necessity to scrutinize the implicit assumptions
adopted by the models of molecular evolution and to develop procedures which rely little on those assumptions.
A follow-up question: what are the new assumptions of the new study?
- Laotian Rock Rat Yep, Its a Living Fossil: The unusual rat-like mammal
found in a Laotian food market in 2005 (05/16/2005)
is a living fossil, reported National
Geographic News. Some researchers claim that it belongs to a family of rodents thought to have
gone extinct 11 million years ago.
- Bears Keeping fit while sleeping: On much shorter time scales (months),
bears manage to keep most of their muscle strength during the winter hibernation.
Science Daily reported that
Bears in this study exhibited remarkable conservation of muscle function.... In spite of a size difference
of almost three orders of magnitude and a 30 degree Celsius difference in torpor body temperature, the black bear
may conserve muscle function to the extent of or perhaps better than small-mammal hibernators.
How the authors entered Colorado bear dens to take the measurements sounds like an adventure to be told somewhere.
Anyone see evolution here? Anyone see millions of years here?
Always scrutinize those implicit assumptions.

More Candy Found in Junk DNA 04/24/2007
 Powerful regulators that play
a crucial role this is how non-coding sections of DNA are now being described.
A story in Science
Daily says that these regions of junk DNA once dismissed as gene
deserts actually orchestrate the expression of genes during development.
In a related paper in PNAS,1 researchers found regulatory
roles for many conserved noncoding elements (CNEs). We identify nearly 15,000
conserved sites that likely serve as insulators, and we show that nearby genes separated
by predicted CTCF sites2 show markedly reduced correlation in gene expression, they
said. These sites may thus partition the human genome into domains of
expression. They found one family that might have a broad role
for gene expression, and other striking examples of novel functional elements.
This realization is opening eyes to a new realm of genetic marvels.
Right now its like being a kid in a candy warehouse, said one geneticist.
Others who looked at transposons and jumping genes as nuisances that were messing things
up now see them as useful. Evolutionists are invoking the E word in various
ways. Transposons might be a major vehicle for evolutionary novelty,
said one, while another remarked about emerging new view of junk DNA, Its funny
how quickly the field is now evolving.
1Xie et al, Systematic discovery of regulatory motifs in conserved regions of the human genome,
including thousands of CTCF insulator sites,
Proceedings of the National Academy of Sciences
USA, 10.1073/pnas.0701811104, published online before print April 18, 2007.
2From the above paper, CTCF, a protein containing 11 zinc-finger domains, is a major
factor implicated in vertebrate insulator activities. An
insulator is a DNA sequence element that prevents a regulatory
protein binding to the control region of one gene from influencing
the transcription of neighboring genes. When placed between an
enhancer and a promoter, an insulator can block the interaction
between the two. Several dozen insulator sites have been characterized,
and almost all have been shown to contain CTCF binding
sites. In some cases, the CTCF site has been directly shown to be
both necessary and sufficient for enhancer blocking activities in
heterologous settings. The known CTCF sites show considerable
sequence variation, and no clear consensus sequence has been
derived.
Its not funny. For decades, Darwinian preconceptions have
held back a promising field of genetic research with their falsified notion that most of
the genome is composed of evolutionary leftovers. Now that we see the design that
was there all along, can we get on with what science should have been doing? Away with
this new plot line that junk DNA is a source of evolutionary novelty.
Darwinians, you have been exposed as usurpers. Get out of the way. The field is not evolving.
Intelligent design is taking back its rights.

Scientists Track Homing Pigeons with GPS 04/24/2007

How do homing pigeons find their way? Scientists are still not sure. They know that
the birds use a sun compass and magnetic fields, but what other cues guide them back to the
specific roost they know as home? A new study shows they are smarter than we thought.
They use multiple cues and weigh the reliability of conflicting ones. Oxford scientists
reporting in PNAS1 tracked the birds with GPS and found some surprises and more questions.
The team outfitted 32 birds with 28-gram GPS loggers on their backs, attached to clipped feathers
with glue and velcro. As a control, they made them do training flights with dummy weights.
Some birds were very familiar with the route; others were novices. This allowed the researchers to
contrast the influence of landmarks (piloting) with compass-guided flight. They tracked the flight
paths on courses up to 10.6 km.
Once the birds learned the way, the experimenters played tricks on them with sun-shifted
release times. They kept the pigeons in light-tight chambers for a week where the sunrise and sunset times
were shifted by 4 hours, corresponding to a 90° shift in sun position. They found that even when these
jet-lagged birds started off perpendicular to the correct orientation, they quickly found parallel routes to the targets.
The scientists concluded that multiple cues are weighed by the birds when they encounter
unexpected conflicting information.
Thus piloting birds continue to maintain memories of,
attention to, compass information even after they apparently
have the sufficient and necessary route-based information
homeward guidance. While it is possible that such compass
memories are, and have always been, associated with representations
of familiar visual landmarks as hypothesized here,
also possible that they originate from an initial, and now residual,
olfactory navigational map. In addition, a potential role for
magnetic compass acting as a backup to the sun compass when
solar and landmark guidance cues are put in conflict (although
apparently not otherwise; see ref. 9) still remains to be explicitly
investigated. Either way, our results clearly indicate that birds
combining multiple sources of onward guidance information
during the local homing task. Both the origin of this compass
information and the function of its integration with landmark
guidance remain to be elucidated.

in familiar route navigation,
Proceedings of the National Academy of Sciences
USA, 10.1073/pnas.0701575104, published online before print April 23, 2007.
Homing pigeons have fascinated humans for thousands of years.
How do they do it? Here we are in 2007, still trying to figure it out. The birds are
not just robots with a compass. They have the ability somehow to choose what cues to follow
when they are in conflict. Theres more going on in a bird brain than we can fathom.
The origin of this compass information
doesnt really need to be elucidated (if by that they think a Darwinian answer is in the wings).
They know where it came from. In plain English, design reveals a Designer. Make sense

Amazing Facts
Fossil Forest Found in Coal 04/23/2007

A Carboniferous forest extending some 4 square miles has been found in the ceiling of a coal mine, reported
Science Daily,
Live Science and
News@Nature.
About 50 species have been identified, including ferns and horsetails over 10 times taller than
those alive today. News@Nature remarked that the forest contained some mangrove-like
plants. The article quoted a surprised researcher who said, It was always assumed
that mangrove plants had evolved fairly recently.
The fossil forest was found in 2005 but was announced today in the online
journal Geology. The area is now 100 meters underground. The research
team believes an ancient earthquake some 300 million years ago caused a sudden lowering of
the area, resulting in the inundation and fossilization of the forest. Another surprise
was that the ancient forest was so diverse for such an early period. This discovery
also shows that the fundamental processes that guide the complexity and evolution of forests
has been around for hundreds of millions of years, News@Nature said.
Is this a mangrove-like plant or a true mangrove?
If the latter, it sounds like a big out-of-order problem for evolution, because mangroves were
not supposed to appear till the late Cretaceous
(source)
and these forests are Carboniferous, over 200 million years earlier. That would be a bigger problem than
finding a living dinosaur. A quick check of the original paper in Geology (May 2007) does
not reveal any mention of family Rhizophoraceae or any of the other mangroves, but that doesnt mean they were
not found. Well have to see if more of the details come to light. In any case,
gymnosperms were not thought to live in mangrove-like habitats.
This story also illustrates, as seen so often before, that wherever
evolutionists look, they find more complexity farther back in time than they expect.

Bursting Moons: Saturns mini-moon Enceladus is seen spouting away from 2.4 million miles in a new
photo from Cassini.
How long has this been going on? (see 03/28/2007,
bullet 2). Another picture of the huge geyser was posted April 18 at the
Cassini site.
Jupiters volcanic moon Io was imaged in action last month by the
New Horizons spacecraft
while passing by on its way to Pluto. The Tvashtar volcano, observed closely by Galileo,
is still going strong, its plume rising 300 km above the north pole of Io. For a colorized version, visit
Astronomy Picture of the Day, April 4.
For background on Ios anomalous heat, see 03/01/2007 bullet 1,
05/04/2004,
10/04/2001 and CEHs very first news story,
08/16/2000.
Update 04/20/24: Slides from an upcoming CHARM telecon about Enceladus have
been posted on the Cassini website.
The presentation (PDF) by John Spencer gives many fascinating details about the Enceladus plume, what
scientists think might be powering it, the best images and data so far, and plans for upcoming flybys.
A new high-resolution, high-phase image of the geyser may arrive in a few days, April 24 (slide 54).
Slide 30 claims that 20% of the mass of Enceladus would have erupted in 4 billion years (that comment
appended by an exclamation point!) and that is with only 1% of the material escaping into the
E ring (slide 39). The power output in the hottest spots (24 watts per square meter, slide 42) exceeds that
of Yellowstone. No variation in output was seen in two observations 16 months apart (slide 49, 51).
Enceladus is now a major target for the extended mission (slide 56).
The close flyby next March 12 (slide 55) will fly right through the plume! Four other close
encounters are planned by end of October 2008 (slide 57).
Update 04/28/24: Apparently Saturns medium-large moon Dione is active, too.
Space.com reported that evidence of
cryovolcanism and outgassing appears to be occurring today on Dione, though at a lesser rate by about two orders
of magnitude. Dione has a diameter about 2.5 times that of Enceladus. Like its smaller neighbor,
Dione has craters that show evidence of modification by heat.

The Evolution of TV Dinners 04/20/2007

Humans still have genetic memories of feasting and telling stories around the campfire, says Martin
Jones at Cambridge University. Thats why we gravitate toward eating TV dinners
in front of the telly. This opinion is expressed in all seriousness by
United
Press International, titled Television dinners linked to evolution.
Jones calls todays TV dinners todays campfire.
The article explains, Martin told the London newspaper [The Telegraph] he believes it is natural
for humans to gather and to eat while also consuming information and entertainment.
Other scientists are not sure about this idea. Martins theory has been
called unhelpful, particularly by groups who attribute child obesity to eating in front
of the television.
Perhaps a few Darwinians worry that the all-seeing eyes of Creation-Evolution
Headlines are ever lurking about the internet, searching for candidates for the SEQOTW prize.
Perhaps there is something to this idea but in a philosophical,
not evolutionary sense. Lost humans have always amused themselves in
Platos cave,
thinking they understand the world, when in reality, their backs are to the light, and they see mere shadows
projected on the wall. Now, we have Hollywood to deliver the shadows to us in our own homes.

Fatty Acid Synthesis: A Machine with High Degree of
Architectural Complexity 04/19/2007

As Bruce Alberts said in 1998, the biology of the future was going to be the study of
molecular machines: the entire cell can be viewed as a factory that contains an elaborate
network of interlocking assembly lines, each of which is composed of a set of large protein
machines.1 One of those machines is like a mini-factory in itself. Its
called fatty acid synthase (FAS). Three Yale researchers just published the most detailed description
of this machine in the journal Cell.2 (cf. last years headline,
03/06/2006). They remarked that its most
striking feature is the high degree of architectural complexity some 48
active sites, complete with moving parts, in a particle 27 billionths of a meter high and
23 billionths of a meter wide.
Despite our aversion to fat, fatty acids are essential to life. Its
when fat production goes awry that you can become fat. The authors explain:
Fatty acids are key components of the cell, and their synthesis is essential for all
organisms except archaea. They are major constituents of cellular membranes and are
used for posttranslational protein modifications that are functionally important.
Saturated fatty acids are the main stores of chemical energy in organisms. Deregulation
of fatty acid synthesis affects many cellular functions and may result in aberrant mitosis,
cancer, and obesity.
The chemical steps for building fatty acids appear in the simplest cells and remain
essentially unchanged up to the most complex organisms, although the machinery differs widely
between plants, animals and bacteria. In plants, for instance, the steps are performed
by separate enzymes. In animals, a two-part machine does the work. Which organism
has one of the most elaborate fatty-acid machines of all? The surprising answer: fungi.
The researchers imaged the fatty acid synthase enzymes of yeast and, despite their academic
restraint, were clearly excited as the details came into focus:
Perhaps the most striking feature of fungal FAS is its high degree of architectural complexity, in
which 48 functional centers exist in a single ... particle. Detailed structural information is
essential for delineating how this complex particle coordinates the reactions involved in
many steps of synthesis of fatty acids.... The six alpha subunits form a central wheel in
the assembly, and the beta subunits form domes on the top and bottom of the wheel, creating six
reaction chambers within which each ACP can reach the six active sites through surprisingly
modest movements. This structure now provides a complete framework for understanding the
structural basis of this macromolecular machines important function.
Calling it an
elegant mechanism, they proudly
unveiled a new model that tells the secret inside: a swinging arm delivers
parts to eight different reaction centers in a precise sequence.
Their dazzling color diagrams are, unfortunately, copyrighted inside a technical
journal, but a Google image search shows one reasonable facsimile of the overall shape at a
Swiss website: click here.
Some of the protein parts provide structural support for the delicate moving parts inside.
Taking the structure apart, it looks something like a wagon wheel with tetrahedron-shaped hubcaps
above and below. Picture a horizontal wagon wheel with three spokes, bisecting the equator of the
structure. Now put the hubcaps over the top and bottom axles. The interior gets
divided up into six compartments (reaction chambers) where the magic
takes place.
In each reaction chamber, eight active sites are positioned on the walls
at widely separated angles from the center.
Spaced nearly equidistant between them all is a pivot point, and attached to it by a hinge is
a lever arm. This lever arm, called ACP, is just the right length to reach all of the
reaction sites. From a tunnel on the exterior, the first component arrives and is fastened
to the ACP arm (priming). The arm then swings over to another active site to pick up the next part,
then cycles through the next six reaction sites that each do their part to add ingredients to
the growing fatty acid chain (elongation). The machine cycles through the elongation step
multiple times, adding carbons to the growing fatty acid. When the chain reaches its proper length (16-18
carbons, depending on the fatty acid needed), it is sent to a final active site that stops the
cycle (termination) and delivers the product through an exit channel to the cytoplasm.
The ACP hinged arm, then, is the key to the system. Imagine a life-size
automated factory with a roughly spherical interior. Its task is to build a chain of
parts in a precise order. The first ingredient comes through a shaft and is attached to
the robotic arm in the center. The arm then follows a pre-programmed sequence
that holds out the product to eight different machines on the walls that add their part to
the product. The final operation of the arm delivers the product to an exit channel.
In a cell, though, how does this arm actually move? The answer: electricity.
Yes, folks, yeast cells contain actual electrical machines. Dont visualize
wires of flowing current; instead, picture active sites with concentrations of positive and negative
charges in precise amounts. How does the lever arm use this electrical system?
Owing to the specific kinds of amino acids used, each active site has a net positive charge, while
the ACP lever arm has a negative charge. Each time a part is added to the product, it changes
the overall charge distribution and makes the arm swing over to the next position. Thus, a
blind structure made out of amino acids follows a cyclic pattern that builds up a specific
product molecule one carbon at a time, and automatically delivers it when complete. After
delivery, the system is automatically reset for the next round. Clearly, the precision of
charge on each active site is critical to the function of the machine.3, 4
Now that we have described one reaction chamber, step back and see that the yeast
FAS machine has six such chambers working independently and simultaneously. Another surprise is
that the lever arm inside must be activated from the outside during assembly
of the machine by a structure (PPT) on the exterior wall before it can work. Theres a
reason for this, too:
The crystal structure of yeast FAS reveals that this large, macromolecular assembly functions as a
six-chambered reactor for fatty acid synthesis. Each of the six chambers functions
independently and has in its chamber wall all of the catalytic units required for fatty
acid priming, elongation, and termination, while one substrate-shuttling component, ACP, is
located inside each chamber and functions like a swinging arm. Surprisingly, however,
the step at which the reactor is activated must occur before the complete assembly of the
particle since the PPT domain that attaches the pantetheine arm to ACP lies outside the
assembly, inaccessible to ACP that lies inside. Remarkably, the architectural
complexity of the FAS particle results in the simplicity of the reaction mechanisms for fatty
acid synthesis in fungi.
Maybe the activation step is a quality-control step, to ensure the system doesnt cause trouble
in the cytoplasm before the machinery is completely assembled.
The authors
did not mention how fast the synthesis takes place. But if its anything like the other
machinery in the cell, you can bet the FAS machine cranks out its products swiftly and efficiently, and
life goes on, one molecule at a time. Baking a cake with yeast will never seem the same again.

3In addition to electrical charges, some amino acids have side chains that attract or
repel water. These hydrophilic and hydrophobic side chains also contribute to the
force fields that cause the conformational changes in the enzyme.
4The diagrams in the paper show the details of each active site. To the uninitiated,
enzyme models appear like random balls of putty stuck together, but humans should not impose their propensity
for straight lines and angles on the world of molecules. The shape and folds of the structure are
critical to the function because they control the charge distribution in the vicinity. The active
sites are recessed within tunnels. The ACP lever arm tip is guided by charge into these tunnels where
ingredients are snapped on to the molecule through precise chemical reactions.
Each reaction changes the charge distribution, leading to the next stage of the cycle.
Reading this paper was almost a transcendent experience.
To imagine this level of precision and master-controlled processing on a level this small,
cannot help but induce a profound sense of wonder and awe. Here, all this time, this
machine has been helping to keep living things functioning and we didnt even know the
details till now. How would such revelations have affected the history of ideas?
The authors did not say a peep about evolution except to note
five times that certain parts are conserved (unevolved). They also assumed
evolution (without evidence) in one astonishing reaction to the fact that certain folds in the
protein parts of this machine are unique in nature: listen They consequentially
represent new folds and may have evolved independently to tether and orient the multiple
active centers of fungal FAS for efficient catalysis. OK, everyone, a
collective rotten-tomato toss for that enlightened suggestion.
Remember that origin-of-life researchers are stumbling and fumbling trying to get
even single amino acids to form (04/04/2007), let alone get
them to join up in useful, functioning chains (see online book).
The fatty acids are useless without the amino acids, and vice versa
(09/03/2004).
Even if some kind of metabolic cycle were to be envisioned under semi-realistic conditions,
how did this elaborate machine, composed of amino acids with precise charge distributions,
arise? Its not just the machine, its the blueprints
and construction process that must be explained. What blind process led to the precise
placement of active sites that process their inputs in a programmed sequence? What put them
into a structure with shared walls where six reaction chambers can work independently?
All this complexity, involving thousands of precision amino acids in
FAS (2.6 million atomic mass units) has to be coded in DNA, then built by the formidably complex
translation process, then assembled together in the right order, or FAS wont work.
But the storage, retrieval, translation and construction systems all need the fatty acids, too,
or they wont work.
We are witnessing an interdependent system of mind-boggling complexity
that defies any explanation besides intelligent design. Yes, Bruce Alberts, as it turns out,
we can walk and we can talk because the chemistry that makes life possible is much more elaborate
and sophisticated than anything we students had ever considered. We have tended to
vastly underestimate the sophistication of many of these remarkable devices.
Yeast. Who could have ever imagined this simple little blob possessed
a high degree of architectural complexity and robotic technology. Many questions remain.
Why do plants and animals
have different mechanisms, but the same chemical steps? Why do fungi, of all things, have
the most elaborate architectures? Are the other architectures equally complex in their own
ways? What other factories regulate this one, and how does this
factory regulate other downstream systems? We have much more to learn about fatty acid synthesis,
but the biology of the future design biology is shedding far more light
than Darwins myths ever did. The fact that life functions so well, from yeast to human,
should spur us on to uncover the design principles that make it all come together as a finely tuned
system, in a finely tuned world, in a finely tuned universe.

Amazing Facts
Spider Silk Admired, Not Duplicated 04/18/2007

Spiders still maintain the edge in a technology humans want: a material that absorbs huge
amounts of energy without breaking. The dragline silk spun by spiders is extremely robust
ounce for ounce stronger than steel, yet more flexible than Kevlar.
If a web the size of a football field could be erected in the air with strands
one centimeter thick arranged in concentric circles 4 cm apart, it could
stop a jumbo jet in flight. (We wont try to envision a passengers view
of the spider sneaking up on the captured plane. Whoops, too late.)
Fascinating facts about spider silk made the
cover story of Science News
(171:15, p. 231, 04/14/2007). Aimee Cunningham told about teams like that of Nikola Kojic (MIT)
that are trying to replicate this ideal material but have not yet succeeded in matching its strength.
Human versions require high temperatures, high pressures and toxic substances to make.
Your humble garden spider has no such limitations:
In contrast, natural spider silk is produced at room temperature with water as a solvent, says
Chris Holland, a zoologist at the University of Oxford in England. Its made
in the spider, and with the spider eating flies. That produces a fiber that we cant
even come close to.
The formula for
synthetic dragline silk is a prize humans eagerly seek. Such a tough and flexible material would
find many applications, from bulletproof vests to suspension cables for bridges. Maybe
even Spiderman toys will come from it. The spider hasnt given us all the secrets,
said one researcher.
Somehow, the spider extrudes a silk dope through ducts in its abdomen, and this
goop solidifies into a strand that is stretchy and very tough. A silk thread contains
hundreds of thousands of protein chains, each of which folds on its own and also arranges itself
among other chains in the fiber. One researcher found that repeating units are able
to snap together like Lego blocks.
Even more amazing, spiders spin seven kinds of silk from the same machinery.
Dragline silk, forming the spokes of the web, absorbs the brunt of the energy. Capture-spiral silk
is stretchy and sticky. Other forms are used to wrap the prey, coat the egg sacs and perform
other functions. One team found that the prey-wrapping silk is up to three times tougher than
dragline silk. This adds drama to that scene of Shelobs lair in The Return of the King.
At this point, the R&D of spider technology is still in the R stage. Spiderman
wannabees will probably not find webshooters under the tree this year. But even though the
researchers interviewed for the article stand in awe of spider silk, they did not shy away from
speculating about how evolution gave the spider a technology our brightest minds cannot emulate.
Spiders and silkworms evolved the capacity to spin silk independently of each other,
said one:
The dopes contain different proteins, and the resulting fibers have distinct properties.
Yet what we see is that the flow properties are very similar, [Chris] Holland [Oxford] says.
Despite their differences, the spider and silkworm use similar tricks, he continues.
This gives fantastic insight into how silk production has evolved and how the production
of an energy-efficient, high-performance fiber is made by nature.
Not only that, it happened a long, long, time ago: Spiders have been spinning these silks for
almost 400 million years. No questions asked.
The evolution-talk ruined an otherwise great article.
Notice that the Darwin storytelling was absolutely useless. Evolution was assumed without evidence
and contributed nothing to helping the scientists on their quest to reverse-engineer the technology.
Most people detest spiders and find them creepy or scary. Lets teach our kids to
admire them and respect them, along with ants, honeybees and the many other critters around us.
Some of our fellow denizens we need to admire at a distance, and yes, its OK to keep them out of the house.
Spiders dont mean to invade your space; they just wander and get disoriented sometimes and need a little help.
Maybe instead of stepping on every spider you see, you should teach kids to scoop them up and let them
play in their own space outside. Your reporter once watched a four-inch-wide
hairy mygalomorph come strutting into
the bedroom just before lights out. Mutually startled, the human jumped up and the spider ran under the bed.
The spider needed a little help for about half
an hour getting rediscovered and assisted into a more suitable habitat. All lived happily ever after.
Help children observe the wonderful ways spiders weave
their webs. Have you ever witnessed the whole web construction process? The material
is amazing enough, but watching how the spider creates the pattern is a lot of fun.
When they wrap their prey, it shouldnt seem that different from what we do with
our food. Think how repulsed a hen in a Far Side Horror Movie would be watching humans cut up a rotisserie
chicken, shrink-wrap the pieces and put them in the refrigerator. Its all in the point of
view. What do you want, a yard full of flies? Spiders do us a service. By capturing, stunning
and wrapping their food, spiders keep their meat fresh and help maintain the balance in nature.
Their ability to turn fly guts into techno-silk should not be minimized. Dont feel slighted.
You can take barbecue chicken and transform it into cerebral cortex.

Keeping the Media Safe for Darwin 04/17/2007

The worlds mainstream science journals often discuss Darwinian ideas. From these
fountainheads, science reporters and popularizers collect and distribute their libations.
Considering that a large population of the public maintains serious doubts that Darwinism is
true, it is instructive to see how issues of origins are stated, and what parts are left unstated.
Here are some examples from the journals and the popularized reports that followed.
It gets really interesting when problems in evolutionary theory are discussed.
- Multicellularity No contest: In an essay in
Nature
April 5, Paul B. Rainey (U of Auckland) speculated that although the origin of multicellularity
is poorly understood, good old Darwinian survival of the fittest rises to the
explanatory rescue: Could the evolution of multicellular life have been fuelled by conflict
among selective forces acting at different levels of organization? The default answer must
be yes, because no hint of a design alternative was even considered. Instead, considering that
the difficulties produce an impossibly difficult challenge for evolution that looks
at first like an evolutionary dead-end, he offered one plausible scenario
and explained it all with game theory, with cells acting as cooperators and
cheaters. Voilathis is by no means beyond the capacity of evolution
given an appropriate selective environment. No debate, no challenge.
- Marine biology Born again: One would think the phrase born again to be patented by
Christians, but Philippe Janvier in the same April 5 issue of
Nature
titled his news article Evolutionary biology: Born-again hagfishes.
Hagfish are jawless, cartilaginous eel-shaped marine vertebrates whose evolutionary ancestry
is confused: the hagfish puzzle, he calls it. Palaeontology sometimes
settles such conflicts. But it is powerless in this case, because the earliest
(300-million-year-old) hagfishes, preserved as soft-tissue imprints, are very similar to living
ones. But is this an opportunity for non-evolutionary hypotheses to get a hearing?
Clearly not. Janvier discussed findings of a neural crest in one species that
possibly made vertebrates more competitive in the early stage of their evolution.
Thus, even in the absence of evidence, Darwinian hopes can be born of water and the spirit:
Further analyses of the developmental genetics of hagfish embryos might enable us to discover
whether hagfish anatomy is primitive or degenerate, and may help in reconstructing the
theoretical common ancestor to all vertebrates.
- Animal behavior Unguided intelligence: A book review in the April 5
Nature mentioned
intelligent and design several times but not together. Tore
Slagsvold reviewed a book called Animal Architects by James L. Gould. Here was a prime
opportunity to discuss theories of intelligent design, but the subtitle of the book reveals the only
point worthy of discussion: Building and the Evolution of Intelligence. The bulk of the
review was only about how animal intelligence and the architectures animals produce might have
evolved. Humans were not exempt. A sample quote: Bower birds are considered to be
intelligent, suggesting that recursive cycles of selection for a single set of cognitive
building abilities and aesthetic refinements are part of the same sort of positive-feedback loop
that may have led to the evolution of the human mind.
- History of science
A bow to our worthy opponents: Lest this list appear overly selective, here is an example where
non-evolutionary ideas got a plug. Peter Dear (Cornell) reviewed a book in the April 12
Nature that acknowledged
the religious motives of many early scientists: Stephen Gaukrogers The Emergence of a Scientific
Culture: Science and the Shaping of Modernity 1210–1685. Dears review was favorable.
It acknowledged the debt of modern science to religion: Far from separating itself from religion,
European science at the time became the principal tool for underpinning it: understanding nature was the
path towards knowledge of God he says (see online book and recent article
by Michael Egnor). And
having attained this status by the 1680s, argues Gaukroger, science hasnt looked back since.
Nevertheless, it could be argued that a historical survey ending in 1685 poses no threat to
Darwinism. By starting the story in thirteenth-century Latin Europe, Gaukroger presents a
world in which theology, not natural philosophy, was regarded as the
queen of the sciences. He then traces how this gradually ceased to be the case,
and natural philosophy, albeit of a new kind, displaced theology as the touchstone
of cognitive propriety. Indeed, the child grew to devour its mother: By the end of the
seventeenth century, many people were arguing that the standards and procedures of natural philosophy
were appropriate models for all kinds of cognitive enquiry, including those involving theology
and religion. The suggestion was that this was a good, progressive trend.
- Morality All men are evolved equal: Whence the human motive for fairness and equality?
One need look no farther than natural selection, according to a team writing in the April 12 issue of
Nature.
Five scientists presented a paper called Egalitarian motives in humans that placed this
noblest of human ideals squarely on an evolutionary footing. They modeled how a sense of fairness
arises through emotions in social groups based on game theory: The results suggest that egalitarian
motives affect income-altering behaviours, and may therefore be an important factor underlying
the evolution of strong reciprocity and, hence, cooperation in humans.
A question arises: WWJD? (What
would Jefferson declare?) In the scientific community, it is no longer self-evident that all
men are created equal, nor endowed by their Creator with certain unalienable rights.
The Founding Fathers were noticeably absent in the footnotes. All 14 references (John Maynard Smith,
etc.) were to Darwinian papers by Darwinian thinkers presenting Darwinian ideas on this question.
- Tetrapods Bite-size Darwin: A paper in
Proceedings of the National Academy of Sciences
suggested that Terrestrial-style feeding in a very early aquatic tetrapod is supported by evidence from
experimental analysis of suture morphology. In other words, fish developed a bite before invading
the land looking for something to eat. A picture story of the whole tale was promptly supplied by
Live Science: Ability to
Bite Evolved in Fishy Ancestors. No other explanation was hinted at, even though the evolutionary explanation
was only tentative: Did fish make the move to land to escape from predators or to exploit new food sources?
Jeanna Brynner asked. Our findings do support the idea that they came on land to exploit new food sources,
but were not sure, one of the authors admitted. Still, the suggestion was fit enough to print.
- Public policy Framed Darwin: Moving on to Science, the problem about what to do with
antievolutionism was discussed. Matthew Nisbet and Chris Mooney in the April 6 issue of
Science equated evolution with
science and anything else as pseudoscience. The article mentioned creationism and intelligent design
in context of other heated social-policy issues like global warming and stem cell research. The idea
was not so much how to hold fair debates on these issues in the marketplace of ideas, but how scientists
should frame their arguments for best effect: Without misrepresenting scientific information
on highly contested issues, scientists must learn to actively frame information to make it
relevant to different audiences. They justified this tactic on the argument that opposed
groups are also framing their arguments.
Yet Nisbet and Mooney hedged a little on whether framing
arguments for social acceptance amounts to a kind of misrepresentation. Somewhat sheepishly, they
stated at the end, Some readers may consider our proposals too Orwellian, preferring to safely
stick to the facts. Yet scientists must realize that facts will be repeatedly misapplied and twisted
in direct proportion to their relevance to the political debate and decision-making. In short, as
unnatural as it might feel, in many cases, scientists should strategically avoid emphasizing the
technical details of science when trying to defend it. This raises many moral and ethical
issues for a group of professionals often on the public dole who are assumed to be objective.
Launching from that word Orwellian, some of the antievolutionists discussed these
issues on Evolution
News and Access
Research Network.
- Genetics Primates Progress: The rhesus monkey genome made the cover of
Science April 13.
There were surprises, but nothing blocked the evolutionary insights from passing through.
One major surprise was that the chimpanzee seems to have more evidence of positive selection than humans.
This anomaly, however, was no threat to big picture of evolution but will undoubtedly
shed light on how natural selection works. The boon for understanding primate evolution
was promptly echoed in Science News
(Primates Progress),
National Geographic,
BBC News and other science news outlets.
- Paleontology
Dino Protein: Because it deserves mention again in this context, recall how the announcement of
protein fragments in dinosaur bone was framed for the media
(04/12/2007 entry).
- Aesthetics Dance for Darwin: Venturing into the arts, an evolutionary ballet called Orion
was reviewed by John Bohannon in Science
April 13. Except for a few simplistic reductions of
complex subjects and trying to cover too much material, it was gorgeously good, he thought. The script is seamless from
big bang to man: the dancers bring the rapidly evolving universe into being....
From here, we dance through the history of the universe along a logarithmic scale.
By the time we reach the midpoint, weve already seen inflation, solar systems, complex molecules,
cells, and multicellular organisms, and judging by the sound of bird song in the distance,
were past the Cretaceous by the intermission. The final act is devoted to the past few
million years of human evolution, both anatomical and cognitive. Bohannon describes some
of the special effects: During a footrace between knuckle-walking dancers, the losers curl up
and play extinct while the survivors gradually stand erect.... A woman peels herself
out of a full-body condom and collapses in a melodramatic ending that is pure performance art.
One wonders if this is a Darwinist answer to the creation of Eve.
- Cell biology
Die, mascot, die: Lets wrap up this list with a classic example of framing an evolutionary argument
that appeared today in the
Proceedings of the National Academy of Sciences.
Everyone tuned to the Darwin vs. Design controversy has heard
about the bacterial flagellum, a molecular outboard motor found in many species of bacteria.
It has become an unofficial mascot of the Intelligent Design Movement (IDM).
Ever since Dr. Michael Behe (Lehigh U) brought the publics attention to this molecular machine he
described as irreducibly complex in his highly influential 1996 book Darwins Black Box,
the flagellum has been a standard-bearer for the IDM.
It is prominently featured in the intelligent design documentary
Unlocking the Mystery of Life.
Could any scientist publishing in a journal be unaware of this?
Yet the paper in PNAS by Renyi Liu and Howard Ochman, which specifically addressed
the problem of the origin of the bacterial flagellum was startling not only for its claims but its omissions.
The reader will search in vain for any mention of intelligent design, or for any footnote reference to Behe,
Dembski, Johnson, Minnich, Nelson or any of the other leading intelligent-design scientists who, for over a decade,
have held up this molecular machine as a falsification of Darwinian evolution. The reader will also fail
to find any mention that alternative explanations exist: only that Elucidating the origins of complex
biological structures has been one of the major challenges of evolutionary studies, and that
The bacterial flagellum is a primary example of a complex apparatus whose origins and evolutionary
history have proven difficult to reconstruct.
Furthermore, the reader will fail to find a
Darwinian mechanism by which a functional flagellum could emerge by mindless mutations and blind natural selection.
Their entire case relies on homology similarities between parts. Since there are some
sequence similarities in the genes that code
for the 50 parts of the flagellum (24 at the theoretical minimum), and since a smaller rotary motor (ATP synthase)
bears a slight resemblance to the flagellum, the authors proposed a Stepwise formation of the bacterial flagellar system
by means of gene duplication and modification. Within a genome, many of these core genes show
sequence similarity only to other flagellar core genes, indicating that they were derived from one another,
and the relationships among these genes suggest the probable order in which the structural
components of the bacterial flagellum arose. They left it unstated how ATP synthase might have
arrived, considering that it is arguably just as irreducibly complex as the flagellum.
Thus all the arguments offered by the IDM against
this kind of structure forming naturally were ignored: the need for all the parts to function together or not at all,
the failure of co-option to account for irreducible complexity all the way down, and the even more
complex assembly instructions, to mention a few. The authors did acknowledge that the Type-III Secretion
System (TTSS) was probably a devolution, not an ancestor, of the flagellum. But the entirety of their
case rested only on similarities between parts. They assumed that this suggests a common
ancestry not a common Designer.
The huge disparity between what the public thinks about evolution and what the scientific community says is
part of a larger problem, said Joel Belz in an editorial for
World magazine (April 21, p. 6).
Without a conversation on major issues, he said, the medias intent remains suspect.
In Seven Big Lies, Belz singled out Evolution as Number One on his
short list of where the big media regularly get it not just slightly skewed but exactly backwards.
Evolution is one of seven Big Lies we are all subjected to virtually all the time:
Amazingly, according to polls , the massesafter at least two generations of
propagandaarent convinced. By majorities of
at least 2-1, they still think God had something to do with where everything came from.
But evolution remains a basic assumption of the elites who control the media. The evidence?
Almost never will you hear an argument. What you almost always get instead is an expert.
Other lies in his list are global warming (experts instead of serious two-way arguments):
abortion (imagine 45 million people dying from any other cause...and then avoiding painstaking media
analysis); homosexuality (Why no serious pursuit of why homosexuals have a life span 20 years shorter
than the general population?); stem-cell research (The mainstream media so often and so consistently
confuse the two practices that their basic honesty has to be called into question); Islam
(But isnt it a hallmark of serious journalism that the truth must be pursued no matter what
the cost?) and pluralism (Basic test: How do the media determine which movements can be
mocked and ridiculed, and which ones cant?).
Belz sums it up: On all these issuesand theyre not tiny, insignificant
social questionswere not asking that the media agree with us. All we want is an honest
discussion. So long as such a conversation is regularly denied, why should we not conclude that
someone actually means to be lying to us?
Undoubtedly, the PNAS flagellum paper will become the new official answer of the Darwinists to
the IDM challenge of how a complex molecular machine could have evolved. It will be cited endlessly in the journals as proof that the
superweapon of the IDM has been defused once for all. Dont be fooled.
Did you notice something? In every case of Darwin spin, the strategy was twofold:
(1) assume evolution (begging the question) and (2) ignore the
opposition (sidestepping). In case that fails, (3) characterize
the opposition as stupid, insane and wicked with association and
loaded words. The popularizers take the oracles of the gods
and decorate them for the public with visualization,
humor, authority and all the other
tricks of the tirade (pun intended, for our proofreaders). One of the
worst offenders is Lie Science (ditto).
The extent of distortion on their evolution propaganda page is breathtaking. It is only
surpassed by the silliness of their arguments.
Now that you know how the Media Machine operates, you can see how the Darwin Party protects and perpetuates its tyranny.
The strategy is repeated in Current Biology, American Naturalist, BioScience and
nearly every other mainstream science journal. Intelligent design scientists and their arguments
are systematically censored. All arguments are framed to keep Charlies corpse
looking fresh and pink, as materialistic utopia marches onward and upward right past their opponents
behind the soundproof barrier.
Arent you glad for the alternative media? If you have a reaction to these revelations,
write here and describe your feelings.

Jurassic Park Gets Overhaul 04/17/2007

How much do we understand the dinosaurs?
ABC News reported on some big-time
updates and revisions being made to the Carnegie Museum of Natural History dinosaur exhibits.
The title of the article is, Getting Their Dinosaur Facts Right, at Least for Now.
The problem is that even though the newest of the dinosaurs are 65 million years old, scientists
understanding of them has been racing along, changing with each new find. So the
Carnegie staff has decided to dismantle and rethink its entire collection.
Our image of dinosaurs comes mostly from what one finds in old sci-fi films big, lumbering creatures,
dragging their tails on the ground. In recent years, scientists have decided they were probably much
more energetic and agile and the way most fossils were displayed was wrong.
Unfortunately, they dont come with instruction manuals, Matt Lamanna, a
paleontologist at the museum, said with a smile.
The project requires a small army of painters, sculptors, welders and former museum staffers
to fix the newly-found errors and set the dinosaurs to rights.
The scientists back then certainly had the best of intentions but
not the best information. Very few of the fossil skeletons they dug up were complete,
so they made educated guesses, sometimes based on their knowledge of other species.
This may satisfy the purists for now. But the article speculated that
years from now, as the scientists learn more, they say theyll probably have to change
the exhibits all over again.
Evolutionists insist that some of their theorys greatest
strengths are the very driving forces of the theory itself: change and adaptation. However,
when an idea that you defend constantly changes, very few would consider that a strength.
Indeed, Charles Darwin himself would scarcely recognize his own theory today.
This is illustrated in scientific interpretations of dinosaurs. When putting the
bones together, they had to place the backs out of joint merely to fit with their beliefs of dinosaur
skeletal structures literally, forcing the evidence to match their theories.
Notably, the Carnegie collection itself has not changed. Those old bones remain the same,
and it is only evolutionists understanding that has changed. And as ABC aptly pointed out,
it will probably all need to be changed again mere generations from now which means that even this
updated display is probably wrong in ways we cannot recognize. So what is racing along?
Understanding? Scientific progress? Human imagination? The bones arent saying.

Are the Red Dwarfs Ready for SETI? 04/16/2007

There are oodles of M-type red dwarf stars. Before now, most SETI researchers didnt
pay them much attention, because their habitable zones are narrow. Also, because the
habitable zones are closer in, any planets in the lucky radius would most likely be tidally
locked to the star, leaving one hemisphere in darkness and the other scorched in ceaseless
heat and light if not sterilized by deadly flares. Those constraints appear to be
loosening, according to a SETI Institute article on
Space.com.
The advantage of M-type stars is their long life. Presumably, this gives
intelligent life more time to evolve and mature. They are also the most common stars.
Its hard for SETI scientists to overlook all that potential real estate, even if not as
suitable as the zone around our sun. Edna DeVore, public outreach director for the SETI Institute, wrote:
Theres considerable interest in the question of whether M-Stars could host habitable planets.
Would the planets be tidally locked with one face always directed toward the M-Star? Would
flares wipe out life on the local planet? If M-Stars could host habitable planets, life may
be much more widespread that weve previously thought. Thus, M-Stars are of interest
to astrobiologists including SETI scientists who are searching for life beyond Earth.
A study just published in the Feb. 2007 Astrobiology journal includes papers from the NASA Astrobiology
Program about the habitability of planets around M-type stars. If DeVores summary is
representative, the papers focused on the long lifetime of the stars as the major reason for exploring
their environments. Though their habitable zones are narrow, potential warming from CO2
in the atmospheres of terrestrial planets was considered, and some of the drawbacks and hazards were
re-evaluated. This particular issue is free for
download at the Astrobiology journal site.
Wishing upon a star does not make SETI dreams come true.
Ms. DeVores article did not delve into the problems: flares, narrow zones, tidal locking.
Notably, she remarked that initial hopes that solar systems would be arranged like ours have been dealt
a blow. We also expected to find solar systems like our own with small terrestrial
planets near the star, and larger gaseous planets farther out, she said. This
particular pre-conception was discarded with the discovery of hot Jupiters on 4-day orbits
about their stars. Theres the fallacy of extrapolating
from a sample of one.
Choosing M-Stars as a backup plan, though, may not be a cause for joy. It might turn out like the following
hypothetical bad-news, good-news joke. Two pioneers crossing a mountain range hope to live
off the bounty of fruit trees on the other side. Upon arriving, the trees that havent
been destroyed are very few and far between. But look, the younger one chimes
in, trying to be helpful. Theres an endless supply of poison oak.
Research Project: Some of the free papers in the
Astrobiology journal deal directly the
problems of flares, tidal locking and other habitability issues of M-Stars. Perhaps one of our readers would
like to evaluate the claims and see if their hopes are plausible. Keep in mind, though, that
finding billions of suitable zones does not imply they have renters. Thats a different question.

Cosmology: Crisis or Confidence? 04/13/2007

What is it with cosmology these days? On the one hand, astronomers seem more confident than
ever. They speak of this as the era of precision cosmology, when the only task
remaining seems to be refining the decimal points; e.g., the first refinements of the cosmic microwave
background (CMB) won John Mather and George Smoot a Nobel Prize this year. On the other hand, there have been
disturbing comments from respectable quarters hinting that if a complete collapse is not imminent,
at least major rethinking is going on. Some of the most fundamental evidences for and assumptions
behind the standard model, presented as fact in popular publications and planetarium shows,
are being questioned.
The confident claims are so ubiquitous as to need no documentation (see, for instance,
11/02/2002, 02/21/2005,
10/31/2006). As reported here
recently, however, there are rumblings of discontent bordering on revolution (see
02/18/2007,
09/05/2006). Alarming statements of cracks in the
cosmological edifice have intensified in recent weeks. Lets take a look at some examples.
- String at the breaking point: As noted previously,
(02/18/2007), string theory seems to be on trial for
impersonating a science. Whats notable in a book review in
The New Criterion,
though, is that for a long time, it has been the only game
