How Life Defends Against Harmful Mutations 01/31/2002
Different populations have different ways of defending themselves
against the destructive effects of harmful mutations, say
David C. Krakauer of the Sante Fe Institute and Joshua B. Plotkin
of Princeton, in a paper Redundancy, antiredundancy, and the
robustness of genomes in the Jan 29
Proceedings
of the National Academy of Sciences. Although presuming
genetic mutations are a source of evolutionary novelty, they explain
that damage must be guarded against.
The authors propose that small populations of large
organisms (like mammals) use redundancy to maintain fitness: i.e.,
copies of genes and backup systems. But large populations of
small organisms, like bacteria, appear to employ antiredundancy
strategies: i.e., they are hypersensitive to mutation, but employ
methods of removing harmful mutants:
Assuming a cost of redundancy, we find that large populations will
evolve antiredundant mechanisms for removing mutants and thereby
bolster the robustness of wild-type genomes; whereas small populations
will evolve redundancy to ensure that all individuals have a high
chance of survival. We propose that antiredundancy is as
important for developmental robustness as redundancy, and is an
essential mechanism for ensuring tissue-level stability in complex
multicellular organisms. We suggest that antiredundancy deserves
greater attention in relation to cancer, mitochondrial disease, and
virus infection.
The authors propose a mathematical model for explaining the dynamics
of redundancy and antiredundancy in differing populations.
Populations exhibiting redundancy have hilly fitness landscapes with
steep, narrow peaks.
Antiredundant populations have a flat fitness landscape with small
peaks, forming a quasispecies of mutants with similar
fitness.
Although this paper is listed in the
category Evolution, it is hard to see how it
helps evolutionary theory. Whether a population is large or
small, it works to shield itself from mutations and achieve stability.
The fitness peak concept comes from graphing fitness as the
vertical axis on a 3D plot of a population. Evolutionists have
been realizing that fitness is not a progressive slope of onward
and upward improvement, but an undulating landscape with peaks
and valleys. A population on a peak is stable, and would actually
have to devolve to get off its peak and onto a higher one.
This is not evolution in the Darwinian sense. It fits in better
with the view that natural selection is a conservative process, allowing
enough variation to compensate for contingencies (like mutations) that would
otherwise destroy the population. The authors do not describe how
evolutionary novelty can become established, nor do they
provide any example of a beneficial mutation. It appears,
therefore, that this paper is promoting a view of life being in a state of
dynamic equilibrium, not upward evolution.

Technology Imitates Nature Dept. 01/30/2002:
Science News
Jan 26, 2002 has a story about how designers are imitating biological
cilia, the little beating hairlike projections on many types of cells,
to coax micro-spacecraft into position. Unlike the complex
biological cilia,
the artificial ones are made of silica and powered by electric heaters
to make them vibrate at about 60 Hz.
Talk of the Walk of Dinosaurs 01/30/2002
The Jan 31 Nature
has two dinosaur articles. A brief communication by four UK scientists
determines the gait of theropod dinosaurs from the extensive
Oxfordshire trackways. They conclude
that the large beasts were able to run and walk, and used different
gaits for each, but additional questions are left unanswered:
Furthermore, the anatomical correlations between leg and hip anatomy
associated with the adoption of wide- and narrow-gauge gaits are not
yet known and we are therefore unable to determine the phylogenetic
distribution of these locomotor styles. Nevertheless, the Ardley
trackways offer new insight into dinosaur locomotor capacity and will
stimulate enquiry into the evolution and biomechanics of large theropod
dinosaurs.
Brian
Maurer discusses the work of Burness on the size of animals related
to land area, asking why dinosaurs grew to be so big:
Dinosaurs present us with a puzzle. In many respects they seemed
to be constructed like warm-blooded animals. Their posture
indicated they were more active than living cold-blooded
vertebrates. They apparently had extended parental care and
complex mating rituals. Yet, ecologically, they filled continents
as if they were cold-blooded. So what on the surface appears to
be a case of convergent evolution between dinosaurs and modern
vertebrates may in fact be the result of unique evolutionary events
occurring in different ways at different times. Dinosaurs lived
in a very different world from any modern animal, and may have
interacted with their environment in ways that have no clear parallels
among living land vertebrates. The more we study them, the more
we get a glimpse into the complex workings of the evolutionary engine.
The references to evolution seem forced. What scientists observe and
what they speculate on about family trees and evolution have no
necessary connection. Maurers comment about the complex
workings of the evolutionary engine could qualify for Stupid
Evolution Quote of the Week. Evolution is a rusting hulk,
not an engine.

Water Lilies: the Missing Link? 01/30/2002
A press release by the
National
Science Foundation argues that water lilies may be a
missing link. The origin of flowering plants, Darwins
abominable mystery, has long
been a problem. Since all angiosperms have triploid endosperm
but water lily endosperm is diploid, it may be represent a precursor
to the divergence of angiosperms from gymnosperms. This is
the theory of two Colorado biologists writing in the
Jan.
31 Nature, who admit (emphasis added):
Recent phylogenetic hypotheses suggest far greater evolutionary
distances between flowering plants and all other extant seed plants than had previously been imagined. Thus, the task of determining the
homologies and evolutionary histories of defining angiosperm characters,
in essence solving Darwin's abominable mystery, appears
as daunting as ever. If diploid endosperm represents the
ancestral condition for flowering plants, a key intermediate condition
in the early evolutionary history of angiosperms has been revealed. ...
The presence of diploid endosperm in an early angiosperm lineage brings
us one step closer to bridging the substantial gap between
flowering plants and their seed plant ancestors.
There is no way to prove this is
a transitional form. Water lilies are doing just fine today
with their diploid endosperm. The NSF project officer gloats
that This is a significant first-time discovery because now
we are a big step closer to understanding the evolution of flowering
plants. Notice his bluffing exaggeration (a big
step closer to understanding the evolution) compared to the
measured optimism of the authors (one step close to bridging the
substantial gap). In actuality, due to other major problems with
evolutionary theories about the origin of plants that keep mounting in
biochemistry, they are taking only small steps north on an iceberg
speeding south.

Birds Evolved Flight Out of Love 01/29/2002
A UC Davis biologist, discontent with both leading theories of the
origin of bird flight, presented his own: parental care.
EurekAlert says that James Carey finds flaws with the two leading
theories: (1) the top-down theory (that wings grew as lizards jumped
out of trees) would predict wings between front and hind legs.
(2) The bottom-up theory (that wings started out as insulation or insect
swatters) would predict that each stage must be advantageous, but
no intermediates are found. So he presents a new theory: that
reptiles, tenderly caring for their eggs, found the trees a safer place.
The report summarizes: In time,
these early ancestors of birds
developed more advanced techniques for caring for their young.
They started to feed their young in the nest, pumping liquid food
or placing small food items in their mouths. They also began
to produce fewer and more dependent offspring and smaller eggs, and
began nesting in bushes and then small trees to better protect their
offspring from predators.
Gradually the forelimbs of these creatures became
feathered and even more elongated, enabling them to better manipulate
their eggs and to parachute from their tree nests to a soft
landing. Later they would develop the ability to glide and
eventually fly by flapping their wings.
Writing in the German journal Archaeopteryx, Carey
also discusses why flying dinosaurs with nonfeathered membrane-like
wings, such as the pterosaurs, became extinct. He
suggests that they perished, not because they were out-competed by
birds but because they lacked the sophisticated parenting skills needed to
cope with a changing environment.
Did you know there was a whole journal
dedicated to
Archaeopteryx,
the discredited link between reptiles
and birds? Weve said it before, and well say it again:
evolution is not a scientific theory, but a
game for storytellers
who amuse themselves by competing for who can tell the biggest whopper.
The only thing worth noting in Careys ridiculous speculation is how he
trashes the other two leading theories for the origin of bird flight.

Briefly Noted 01/29/2002
Gleanings from the Proceedings of
the National Academy of Sciences Jan 29 online preprints
(emphasis added in quotations):
- Biochemistry: A team describes a
Human
Elongator Complex
that helps in the DNA transcription operation. The introduction
states, The formation of a transcription initiation complex at a
particular promoter is a complicated and highly regulated
process. However, the establishment of a transcription initiation
complex seems much simpler than the process of transcription elongation
with respect to the chromatin impediment, where the elongating
polymerase has to traverse a nucleosome approximately every 200 base
pairs. They describe how human Elongator performs
just this function.
- Biochemistry: A
team from
the Netherlands describes a second endonuclease enzyme that
aids in DNA excision repair (see our Jan 4 headline on
DNA Damage Response). This enzyme they
named Cho is even more effective than UvrC and appears
to come into play when the other repair enzymes are unable to complete
the job: If, however, a specific lesion remains because UvrC is
not able to induce 3' incision as argued above, a replication block
at this damage to which UvrB will probably remain bound will trigger the
SOS response, resulting in expression of the Cho protein. The Cho
protein in its turn will attempt to incise the preincision complex.
When this incision is successful the UvrC protein will induce the second
incision and the repair process can be completed. ... Taken together, the
combined action of UvrC and Cho broadens the substrate range of nucleotide
excision repair in E. coli. E. coli, is, of course,
a lowly bacterium, mindless of these fail-safe mechanisms taking place
within its interior.
- Fossils: Symbiotic bacteria and protozoa have been found in the gut of a
remarkably preserved
termite preserved in Miocene amber presumed 20 million years old.
The organisms markedly resemble those in living termites.
- Evolution: A team of geneticists writes that
mtDNA from fossils reveals a radiation of Hawaiian geese recently
derived from the Canada goose. The surprising and unexpected
results lead them to postulate a case of convergent evolution.
- Evolution:
Biologists from
Utah have found a gene for gamma-carboxylation, long thought to be
a vertebrate specialty involved in blood clotting, in a marine mollusc
Conus. The gene had remarkable similarity to its human
counterpart, and to a gene in Drosophila (fruit fly) whose function is
unknown:
The unexpected conclusion that emerges from our study of the
Conus gamma-carboxylase gene is that all eight introns in the
human gene, corresponding to the Conus genomic interval analyzed, are
evolutionarily ancient, older than the Cambrian explosion (~540 million
years ago) when the molluscs and chordates are first detected in the
fossil record. This finding raises the intriguing question of
whether most introns in other human genes have a similarly ancient
lineage. Our results suggest that Drosophila (and perhaps,
other insects) may not be the appropriate invertebrate standard for
evaluating whether vertebrate introns are likely to be relatively
recent or more ancient than the Cambrian explosion.
Surprises, always surprises, for those
who think evolution explains everything.

Compound Eyes Evolved Multiple Times 01/29/2002
The molecular phylogeny wars are heating up again.
Todd Oakley, biologist at Duke university, writing in the Jan 29 preprints
of the Proceedings
of the National Academy of Sciences explains three reasons biologists
have assumed that compound eyes had a single origin: (1) detailed
similarities appear between diverse groups, even at the gene level;
(2) the number and arrangement
of cells in the eyes of diverse groups are similar; and (3) the neural
circuitry is the same (conserved) across diverse groups of arthropods.
These would seem conclusive, but Oakley argues based on molecular evidence
that compound eyes evolved multiple times separately.
The abstract states (emphasis added):
Eyes often take a central role in discussions of evolution, with
debate focused on how often such complex organs might have
evolved. One such debate is whether arthropod compound eyes
are the product of single or multiple origins. Here we use
molecular phylogeny to address this long-standing debate and
find results favoring the multiple-origins hypothesis. Our
analyses of DNA sequences encoding rRNA unequivocally indicate
that myodocopidsthe only Ostracoda (Crustacea) with compound eyes are
nested phylogenetically within several groups that lack compound
eyes. With our well-supported phylogeny, standard maximum
likelihood (ML) character reconstruction methods significantly
reconstruct ancestral ostracods as lacking compound eyes. We also
introduce a likelihood sensitivity analysis, and show that the
single-origin hypothesis is not significantly favored unless we
assume a highly asymmetric model of evolution (one favoring eye loss
more than 30:1 over gain). These results illustrate exactly
why arthropod compound eye evolution has remained controversial,
because one of two seemingly very unlikely evolutionary histories must
be true. Either compound eyes with detailed similarities evolved
multiple times in different arthropod groups or compound eyes have been
lost in a seemingly inordinate number of arthropod lineages.
If his multiple-origin hypothesis is true (and he sounds confident
it is), then other ways of inferring evolution are all wet:
Our molecular phylogeny clearly indicates that myodocopids are
monophyletic and are nested within several groups lacking compound
eyes. Based on this phylogeny, methods of character
reconstruction significantly favor the independent origin of myodocopid
compound eyes, constituting the strongest phylogenetic evidence to date
for multiple origins of arthropod eyes. If this is not an
independent origin, and compound eyes were actually lost many times,
then this is a case where commonly used methods of historical inference
are positively and significantly misleading. (Emphasis added).
The gullibility of evolutionists is
positively and significantly astounding.
Of course eyes are more easily lost than formed. Why is that
hypothesis hard to believe, unless it fits in with creationist principles?
Instead, in order to rescue evolution at all costs,
he is more willing to believe that organs
that gave Darwin cold shudders evolved multiple times.
Read Michael Behes
description of vision, then realize
that Oakley assumes that a naturalistic miracle occurred not just once, but
numerous times, resulting in structures that are nearly identical!
This story illustrates two things: (1) the growing tension between
molecular phylogenies and morphological phylogenies (genes vs looks), and
(2) the dogma of Darwinism. Evolution is a fixed parameter that must
not be challenged, questioned, or doubted, no matter the evidence.

How Did Jellyfish Fossilize in Wisconsin? 01/25/2002
The February issue of
Geology, Vol 30. No. 2, has a paper
attempting to explain a rare fossil deposit of Cambrian jellyfish.
Commenting on the paper,
EurekAlert
asks, What are those big jellyfish fossils doing in Wisconsin?
Its rare to find a jellyfish fossilnot having a skeleton,
they easily decay. So why is an entire horde of them preserved in
central Wisconsin? The theory of Whitey Hagadorn of Caltech and
his research team is summarized: They believe that the jellyfish were
preserved because of a lack of erosion from sea water and wind, the lack
of scavengers, and the lack of any significant sediment disturbance by
other organisms after the jellyfish were stranded in the sand.
These Cambrian jellyfish are the largest known in the entire fossil record,
about four inches in diameter, but some up to 20 inches.
Apparently they were deposited when Wisconsin had a tropical environment.
The summary in
New
Scientist has pictures of the fossil impressions. See also the
Jan 30 entry in Nature
Science Update which quotes another paleontologist saying, They
must have been buried extremely quickly.
What stranded hundreds of jellyfish
in the sand? We see
stranded
jellyfish on the beach occasionally today, but they are not being
fossilized. It would seem any slow, gradual process would not explain
the fossilization of such soft-bodied organisms, because they would
decay quickly. The abstract begins,
Fossilized impressions of soft-bodied organisms are exceptionally
rare in coarse-grained strata. Fossilized mass-stranding events
of soft-bodied organisms are even rarer. This is only one of
two such deposits known. The authors have to postulate several
improbable settings (lack of scavengers, no erosion for hundreds of
millions of years) to account for the deposit.
Is it possible these medusae were
quickly buried by
deep flood sediments? The fact is, no one was there to know.
All one can do after the fact is postulate a scenario that is consistent with
the present evidence.

Horsehead Nebula Unveiled in New Detail 01/25/2002
Images of the famous Horsehead Nebula in Orion
photographed by the
European
Southern Observatory Very Large Telescope (VLT) have been

impressive color and detail comparable to those taken
by the Hubble
Space Telescope.
The caption says that
the nebulas structures are only temporary as they are being
constantly eroded by the expanding region of ionized gas and are
destroyed on timescales of typically a few thousand years.
The Horsehead as we see it today will therefore not last forever and
minute changes will become observable as the time passes.
Truly stunning photographs, not considered possible from a ground-based
telescope just a few years ago. Notice that the Horsehead
is an eroding feature, not an evolving one, and eroding quickly at that.

Scientists Get Seals-Eye View of the Ocean 01/24/2002

Muslims Use Scientists as Unwitting Defenders of Quran 01/23/2002
According to an article in MSNBC,
Western scientists are sometimes being quoted out of context to
support claims that the Quran must be from God because it is
historically and scientifically accurate in every detail.
For instance, Dr. Joe Leigh Simpson, a Presbyterian, made some
comments in the 1980s at a conference that he now says
sound silly and embarrassing taken out of context about the Quran
and embryology, but he is being quoted as a champion of the book.
Simpson is just one of several non-Muslim scientists who have found
themselves caught up in the publicity machine of a fast-growing branch
of Islamic fundamentalism.
Dubbed Bucailleism, after the French
surgeon Maurice Bucaille, who articulated it in an influential 1976
book, the doctrine is in some ways the Muslim counterpart to Christian
creationism. But while creationism rejects much of modern science,
Bucailleism embraces it. It holds that the Quran prophesied the Big
Bang theory, space travel and other contemporary scientific
breakthroughs. By the same token, it argues, the Bible makes lots of
scientific errors, and so is less reliable as the word of God.
The article discusses how one of the most ardent advocates of
Bucailleism is Sheikh Abdul Majeed Zindani of Yemen, who happens to
also be a friend and mentor to another Bucailleism devotee of
Yemeni descent: Osama bin Laden.
Our Baloney Detector
is flashing many colors on this story. Read the article and then
see if any of these fallacies rear their heads, either from the Muslim
apologists or the comments by MSNBC columnist Daniel Golden:
half truth, guilt by association, card stacking, analogy,
glittering generalities, post hoc, either-or, authority, and bluffing.
The remark about creationism rejecting much of modern
science is close to a Big Lie, and assumes the myth that evolutionary
storytelling is science. Check out this
Answering
Islam site to see if the muslims are being fair in their use of science
to support the Quran. And decide if any of the Quran quotes they

leech supports embryology?). Compare these with
Biblical examples of
scientific accuracy. See who wants you to think, compare,

Bats Upset the Taxonomy Belfry 01/23/2002
A paper by six taxonomists in the Jan 22
Proceedings
of the National Academy of Sciences tries to untangle the confusing
family tree of bats. Stating that The recent history of bat
systematics is rife with controversies, the authors admit that
Morphological evidence does not agree with molecular evidence,
i.e., family trees based on looks do not agree with those based on
DNA. After discussing the pros and cons of conflicting schemes
for grouping microbats (little bats) with megabats (large bats) from
the new and old worlds into larger groups of mammals, these authors
decide from their molecular evidence that some characteristics such
as echolocation through the nose evolved independently by convergent
evolution. They also acknowledge that the oldest known fossil
bat is a microbat. Their proposed solution, they grant, is
in striking contrast to traditional taxonomy, and that
features of the chiropteran skull associated with the nasal
emission of echolocation have more complex evolutionary histories
than previously believed. See also this summary on
Science
Now posted the day after we reported this story. It states,
But evolutionary biologists are quick to note that the work will
likely fuel an already fierce classification controversy in the bat world.
The evidence is a welter of conflicting
characteristics that do not fit naturally into an evolutionary tree.
Notice that the oldest known bat is already fully developed as a bat.
These authors debunk the hypothesis that bats evolved from flying lemurs, but
lump them in with moles, anteaters and carnivores! Yet associating
bats with any other mammal group is pure fiction. And again, as we
have reported here
repeatedly, the molecular and morphological
phylogenies dont match. And trying to explain complex features
by convergent evolution is pure hand waving, expecting us to
believe that unlikely events occurred more than once. Its not
just the mouth or nose that are adapted to the bats amazing
ability to use sonar, but the ears, the brain, and the whole body.
Have you watched the olympic-level aerobatics these animals
perform as they pinpoint the location, size and direction of an insect
that is darting about, and scoop it up in flight in total darkness?
Now the evolutionists expect us to believe this incredible suite of
interrelated hardware and software evolved twice, without a programmer.
Lets get real. The evidence shows, as is the rule, that
complex abilities like bat sonar are already fully developed or have
degenerated
(if some bats lost this ability), but are not seen getting better.
Nothing in living or fossil forms supports the notion that unique
bat characteristics like this evolved through gradual steps. There
are no transitional forms. That is the observational evidence;
evolutionary ancestry theories are forced on uncooperative data, something
like gathering pieces from a thousand unconnected puzzles (thats
how many species of bats there are) and trying to
fit them into another imaginary picture none of them match. If the
preconceived image is wrong, partial success is not progress.

How Similar Are Modern Humans to Archaic Humans? 01/22/2002
Three anthropologists have tried to figure out what skull characteristics
distinguish modern humans from archaic forms like Homo
neanderthalensis. Writing in the Jan 22 preprints of the
Proceedings
of the National Academy of Sciences, they have settled on the
retraction of the face and the roundness of the skull (neurocranial
globularity) as markers, after comparing 100 modern individuals with
bones in the National Museum of Natural History. Their paper,
however, contains a number
of serious admissions of doubt (emphasis added):
- Despite much data, there is no unanimity over how to define
Homo sapiens in the fossil record.
- Paradoxically, our own species, Homo sapiens, is one of the
most poorly defined species of hominids. The recent
human fossil record has a confusing pattern of variation, with numerous
vaguely defined taxa (e.g., archaic H. sapiens,
modern H. sapiens, Homo heidelbergensis, Homo helmei,
Homo rhodesiensis), most of which are not widely accepted.
- ...an increasingly popular view is that AMHS [anatomically modern
Homo sapiens] is a distinct species [based on genetic evidence]. ...
Testing this hypothesis by using cranial features, however, is a
challenge because of the substantial integration that occurs among the
various semi-independent units of the cranium.
- ...further
analyses are necessary to test whether and how growth differences explain these contrasting patterns, especially in terms of facial retraction
and neurocranial globularity.
- [on whether moderns and Neanderthals might have had different
growth patterns.] However, the available sample of
infant AH [archaic human] crania is too small and insufficiently complete,
particularly in the basicranium, to test directly the effects of facial size,
cranial base flexion, anterior cranial base length, and middle and
anterior cranial fossae size on cranial ontogeny. In addition,
there are no well-preserved fossil Neanderthal crania with undistorted
or complete cranial bases, and none younger than 2.2 postnatal years,
by which time most cranial base growth (e.g., flexion) is complete.
- Although a universally acceptable definition of the species unit is a
quixotic endeavor, both phylogenetic and evolutionary species concepts
agree that species should be monophyletic lineages, evolving separately
from other lineages... [thus modern humans appear to be a distinct
species from Neanderthals].
- We have much to learn about the complex processes of cranial growth
and integration, but the above results highlight how efforts to tease
apart these processes have the potential to yield better characters for
testing systematic hypotheses, and to identify possible
targets of selection during speciation.
In spite of the fragmentary data, the authors speculate on which features
appear early in development and which are influenced by environment, such
as heavier brow ridges due to heavier chewing.
They conclude on an optimistic note:
It is exciting to consider that only a few small
shifts in growth, probably in the brain and possibly in the cranial base,
may be responsible for most aspects of the evolution of modern human
cranial form. Viewed in this light, the origin of modern human
cranial form is more likely a result of relatively minor morphogenetic
tinkering than a major shift in developmental processes.
Theres that word tinkering
again; who is the tinkerer, we ask? As usual, the admissions in
this paper are more interesting than the details of bone measurements.
The quotations above demonstrate how much is pure inference and speculation,
how much disagreement there is between anthropologists, how little
is actually known, and how fragmentary the evidence is. This is
how it is written up in the scientific papers, but a very different tale
is told on the Discovery Channel, National Geographic and your
local museum, where artistic license trumps scientific integrity as you
watch actors or mannequins dressed as hairy apemen hunched over in their
caves.
An image of positive proof is portrayed to the masses who will watch a
TV show, but cannot afford
a subscription to PNAS and would get lost in the jargon jungle wherein
the most damaging admissions are communicated. Thats why
were here. Scientific journal notwithstanding,
we show that these evolutionists have presented nothing that would
convince a skeptic who does not already believe man evolved from an
ape-like ancestor, but instead admit numerous problems that undermine
their case. All the
nit-picking over what bone angle and density means to your past sounds
no more convincing than what the folds in a goat liver mean to your future.

India Fossils Too Old for Evolution 01/22/2002
If the rocks in central India are as old as new uranium-lead dates
indicate (1.6 billion years), evolutionists have a problem.
The rocks contain apparent worm burrow markings, which would put
complex life before the Cambrian explosion. These rocks had
been claimed to be ~1 billion years old, and therefore the oldest
fossil evidence for life, but others have contended the rocks are
only 540 million years old. The new date is published in the
Feb 2002 Geology, with
Possible implications for early evolution of animals in
the title. The abstract states, given the doubts expressed
about the origin of the bedding-plane structures, as well as the
surprisingly old age of the host rocks, further studies
are urgently required to provide supportive evidence. (Emphasis
added.)

Science
Magazine makes the claim they are not fossils, but just mud cracks.
Another paper in the
same issue of Geology arrives at similar range dates for these
Vindhyan Supergroup rocks, which calls into
question the identification of fossils found within them.
The authors are not sure who is wrong; These findings are in
conflict with the report of Cambrian small shelly fossils and fossils
of articulate brachiopods in the Rohtasgarh Limestone and argue for a
Mesoproterozoic age for the formation that contains the alleged
trace fossils. Reports of an Ediacaran fossil Spriggina(?)
from the Lower Vindhyan Supergroup from the northern margin of the
Vindhyan Basin suggest either incorrect stratigraphic correlation of
units or misidentification of this fossil.

dates alleged by geologists. Did you notice that the dates disputed by
geologists differ by 1 billion years, the size of the average?
Thats 100% error. Then why feel shy about asserting these
formations as only
a few thousand years old? With error bars this large, it would
appear any date you want is on the table.

Impact Dust Didnt Kill the Dinosaurs 01/22/2002
The Chicxulub crater in the Yucatan, considered by many to be the
smoking gun of the impact that led to the extinction
of the dinosaurs,
apparently wasnt loaded with enough gunpowder to do the job.
In a paper in the Feb 2002 Geology,
Kevin Pope examined impact ejecta at the Cretaceous-Tertiary
boundary layer and estimates there was far too little fine dust lofted
by the impact to affect the climate.
In the abstract, he states: These findings indicate that the
original K-T impact extinction hypothesisthe shutdown of photosynthesis
by submicrometer-size dustis not valid, because it requires more than
two orders of magnitude more fine dust than is estimated here.
Furthermore, estimates of future impact hazards, which rely upon
inaccurate impact-dust loadings, are greatly overstated.
See additional comments by Pope in the summary on
EurekAlert posted the day after we reported this story.
Better go back and revise all the Discovery
Channel documentaries, especially the last episode of Walking with
Dinosaurs, unless you enjoyed it as pure science fiction.

Ohio School Board Fights Over Softening Darwinism, Teaching Design 01/18/2002
Another Kansas-style revolt against evolutionary dogmatism is heating up in Ohio, according to
Phillip Johnson in his Weekly
Wedge Update. Some board members want the science curriculum for K-12 to present
evolution as assumption, not fact and allow freedom to teach the alternative
intelligent design viewpoint, but other board members are afraid of lawsuits and
criticism from science education organizations.
Johnson has promised an update on this developing story
when he returns from a speaking engagement. Expect the usual rhetoric from the
Darwinists about stealth creationism and separation of church and state. Will light

Army Spins Spider Web 01/18/2002
Spider silk has long been admired by material scientists for its
unique combination of high-performance properties including toughness,
strength, lightness and biodegradability, says a report on
EurekAlert
about a joint project by the US Army and Nexia, a biotechnology firm,
that have just announced success in producing fibers of recombinant
spider web silk. The report is published in the
Jan 18
Science. The new fibers, named BioSteel, may show up some day
in biodegradable fishing line, soft body armor, medical sutures
and many other environmentally friendly products. To mass-produce
BioSteel, Nexia is raising genetically modified goats that produce
milk containing the protein for its patented process, ten years in the
making during an agonizingly slow research program.
(No one has been able to herd spiders or find
neighbors that would want to live next to a spider ranch.)
Spider silk is five times stronger, by weight, than steel, yet is
flexible and non polluting, both in its manufacture and degradation.
Spiders can create different weights of dragline with different amounts
of stickiness. Nexia has finally achieved the holy grail
of materials science by getting the proteins to form fibers without clumping;
and while they are flexible and strong, they still are not the equal of
the natural stuff. Dr. Jeffrey Turner, CEO of Nexia, praised
the lowly spider:
Its incredible that a tiny animal found literally in your
backyard can create such an amazing material by using only amino acids,
the same building blocks that are used to make skin and hair.
Spider silk is a material science wonder - a self-assembling,
biodegradable, high-performance, nanofiber structure one-tenth the
width of a human hair that can stop a bee traveling at 20 miles per
hour without breaking. Spider silk has dwarfed Mans
achievements in material science to date.
He described the spiders method of producing this remarkable
substance as a process that has been perfected through 400
million years of evolution.
That last line spoils the story.
Its like the punch line of a bad joke, or finding
a fly in a delicious soup. How can these scientists
wax eloquent in their praise of natures wonders, then
ascribe it all to mindless, purposeless, undirected, unintelligent
forces acting over millions of years? There is no intelligence
or power in mutations or natural selection to organize
thousands of left-handed amino acids in the precise order required to produce
biological steel, let alone to create a tiny robot able to secrete it and
arrange it into a geometrical web. Some day, some day these
naive statements by evolutionists are going to be laughed at by
incredulous readers as the bad jokes they are.

Why Does Titan Still Have an Atmosphere? 01/17/2002
Exclusive The worlds leading
planetary scientists, gathered
for a quarterly planning session at the Jet Propulsion Laboratory for
the Cassini Mission to Saturn
and Titan, discuss many topics. This reporter was conversing
over lunch with a leading atmospheric scientist about the nature of
Titan, target of the
Huygens
Probe riding along Cassini, which (hopefully) will make a soft landing
on the surface in January 2005.
This individual, a key instigator and principal investigator of
Galileos
probe that parachuted into Jupiters atmosphere
in 1995, explained that the evolution of Titans atmosphere is a
problem; it should be long gone by now. Methane in Titans
thick atmosphere provides enough greenhouse effect to sustain the nitrogen
and other ingredients which rain down ethane, acetylene and other hydrocarbons
onto the surface continually, forming a fluffy snow possibly a hundred meters
thick or more. But unlike earth, Titan has no cycle to
recirculate these ingredients, so why is the process continuing today?
Furthermore, solar radiation is eroding
the methane space blanket. When enough methane has been depleted, the
atmosphere will collapse, because the temperature will fall enough to
condense out the nitrogen, carrying it and all the other ingredients down to
the surface. Dr. Atreya put 100 million years as an upper limit on
the sustainability of Titans atmosphere only about one fiftieth
of the assumed age of the solar system. He had no explanation for
why Titan has such a dense atmosphere today, other than perhaps it formed
recently by some unknown mechanism, and we are lucky to see it. When
the reporter remarked that such an answer sounded like the same one the ring
scientists give for why we see Saturns rings (which are also very
short lived), he agreed, with a grin of chagrin.
100 million years is the upper limit;
it could be far less. Whenever you are told the earth and universe
are billions of years old, dont just swallow it: ask questions.
That the earth is 4.5 billion years old is one of those
truisms that everybody knows because the Discovery Channel says so,
but what is the evidence? Here
is another case of a phenomenon that doesnt fit. Its not
that scientists cant find a way to fit anomalies into the timeline;
the important lesson is that the timeline does not come from the data, but
from the assumptions. Be bold and question the assumptions.

Darwinists Question Batemans Principle of Sexual Selection 01/17/2002
A news feature in the Jan 17
Nature, Sexual Stereotypes,
discusses the rethinking of ideas about behavioral biology and sex.
In 1948, Angus John Bateman formalized a hunch of Darwins that
evolution progresses by producing males that are aggressive and profligate
while producing females are coy and choosy. Bateman studied fruit
flies and concluded that promiscuity is more
advantageous for males than females. Batemans principle
was extended to the entire animal kingdom, even humans, and became accepted as
a truism. Since the 1970s, however, dissenting voices have
arisen. Now, even if agreeing with the principle in part, scientists
see the idea as simplistic: Today, behavioural biologists are
finding evidence that the world of sex is more complicated than Bateman
thought. Its not that his principle is invalid, they say,
but rather that it has been used to extend dated preconceptions about
human sexual behaviour to the entire animal kingdom, sometimes to the
detriment of scientific knowledge. ... another example, perhaps, of
the truth being obscured by nineteenth-century sexual stereotypes.
Our Baloney Detector
is beeping on analogy,
extrapolation,
personification, and
glittering generalities.
How many other Darwinian ideas
could be described as simplistic, projections of human stereotypes on
the animal kingdom, and detrimental to scientific knowledge?
Even today, Darwinian truisms have provided a pseudo-scientific
rationalization for all kinds of immoral human sexual practices (see
the PBS Evolution TV series
episode five,
Why Sex? for a recent example). Science cannot provide
justification for promiscuity. Which animal model should man
follow, the birds that mate for life or the bonobos that have group sex?
Any sexual fantasy can find a counterpart in nature that either
supports it or argues against it. Science can only observe, not
command; it has nothing to say to our human moral and ethical
requirements. We are persons made in the image
of God, not fruit flies. What God designs or allows for animals is
His prerogative, but for humans, He commanded,
Thou shalt not commit adultery. Consider whether that
command is trustworthy before rationalizing your life choices on a Darwinian
principle that tomorrow may be dismissed as a myth.

Wonders of the Salt Gate 01/17/2002
A paper in
Nature 1/17/01 describes for the first time
a detailed description of one of the cells chloride channels,
complex pores in the cell membrane that allow negative ions like
Cl- from table salt to pass through, but restrict others.
(For a good laymans summary and illustration, see this news release on the
Howard Hughes
Medical Institute website.)
Thomas Jentsch describes this as another
spectacular breakthrough by Roderick MacKinnons team.
He opens with an explanation: Ion channels are proteins with a
seemingly simple task - to allow the passive flow of ions across biological
membranes. But this process requires more sophistication than one
would imagine.
The
full text of the paper reveals these channels to be amazingly different
than cation channels (those that allow positively charged ions), and
are shown to be exquisite protein complexes with gates composed of
negatively-charged tips (that would normally repulse chloride ions)
that apparently swing out of the way to let the desired molecules in.
The authors explain the importance of these chloride channels:
Potassium, sodium, calcium and chloride ions are used
ingeniously by living systems in the performance of fundamental
cellular tasks. Through the action of ion pumps, a large fraction
of a cells metabolic energy is spent establishing transmembrane ion
gradients. These gradients, through the action of ion channels,
are used to produce electrical signals, activate signal transduction
pathways, regulate cell volume, and mediate fluid and electrolyte
transport. To carry out these tasks, an ion channel has to be
selective, that is, permit only certain ionic species to flow through
its pore.
The precise placement of charged ends of amino acids along the pore
attracts the chloride ions down the channel, without being so attractive
that the ions would bind to them and get stuck.
Failure of these channels is implicated in some serious muscle and
kidney diseases. Some animals have such
a multitude of these effective ion pumps, they can generate a
powerful electric shock. Says Jentsch: On the basis of elegant
biophysical studies by Miller and White, who showed that the electric
ray Torpedo contains large amounts of a peculiar anion channel,
the first voltage-gated Cl- channel was cloned by my group in
1990. We named it ClC-0, as we assumed that it would found a
family of Cl- channels. This turned out to be true:
CLC channels are found in all kingdoms of life, with humans alone having
nine different CLC genes.
The electric ray can
generate 200 volts. On another related front,
EurekAlert
reported the next day that the UMass scientists have
found microbes on the bottom of the sea that generate electricity,
and the Navy is interested in harvesting these microorganisms
to create living batteries. See the original paper in the
Jan 18
Science.
Speaking of protein families, two creationists writing in the
TJ
Technical Journal 2001 #3 (posted on AIG 16-Jan-02) illustrate how
they make
a powerful case for design and argue against a naturalistic origin.
Update 03/04/2002:
Scientific
American posted an interview with MacKinnon about how his team made
its discovery, and how the potassium channel works. In passing, he
comments, ...the cavity and these helices were just a marvelous
arrangement that Mother Nature used to solve this problem, you know, as
if a very brilliant engineer did it all. I think that was very
satisfying to see.
Update 12/30/2002: In a new paper
in the 12/27/02
issue of Cell,
MacKinnon describes how another type of potassium channel acts as
a sensitive biological rectifier.
All the statements we made about the
wonders of the Water Gate on Dec. 20
apply here, and then some. The cell membrane is covered with
these specialized pores that have selectivity filters and
gates to attract and conduct desired molecules in, but keep unwanted
invaders out. All life has them, they are all extremely complex,
and without them life could not exist.
Compare the above empirical facts with the stories
evolutionists tell about the origin of a living cell. They
usually describe some lipid membrane spontaneously assembling through
electrostatic or hydrophilic attraction into a seamless bag.
Inside are a few RNA nucleotides, amino acids, sugars, and other building
blocks of life (hopefully without nasty oxygen or killer tar
molecules doing their worst). But if the membrane is sealed,
without the ability to perform
active transport of needed ingredients to the inside
or remove unwanted toxins to the outside, the primitive cell
becomes a death trap. The molecules inside are all that
evolution has to work on, like those old jokes about being trapped
in a locked room with Hitler, Stalin, a lawyer and only two bullets.
The situation is not going to improve. Even if by some inconceivable
magical
miracle something wonderful happened inside this infinitesimal subset of
primordial soup, it would still be a death trap.
Unless the protocell could divide into two identical copies,
natural selection, that magic wand of Darwinism, would be powerless.
On the other hand,
if the membrane were leaky, osmosis would dictate mindlessly that the
leakage would go from higher concentration to lower concentration,
the opposite of what a living cell needs. For instance, a cell
needs to be able to import precious water when the environment around
it is drying up, but osmosis would guarantee the reverse, desiccating
the poor cell. For these
reasons, the simplistic evolutionary models of primitive membrane
formation by spontaneous attraction of molecules are unrealistic.
The observations show that all living things, even the most
primitive, already have entire families of these sophisticated
gates to control what goes in and out of the cell. There are
no simple-to-complex intermediates known, and it is unlikely any
could even be conceived that would give rise to working active transport
without a host of genes and proteins controlling the construction and
operation of these highly specialized and effective mechanisms.
MacKinnons paper only mentions evolution twice.
For example, Thus, it would appear that evolution of the
channel has resulted in partial charges to stabilize a Cl-
ion and still permit rapid ionic diffusion rates. Yet
he fails to provide any plausible story how this could have happened by
mindless processes; he basically just admits that it is an elegant arrangement.
So how would the Intelligent Design (ID)
approach explain it? Evolutionists sometimes complain that
ID or creationism simply gives up and says God did it,
but that is a caricature. It is sufficient for science to
describe the phenomenon including its information content
(including the DNA software and protein construction toolkit) without
specifying who done it (to use Eugenie Scotts
favorite vulgarism). Strictly speaking, empirical science
cannot address the Who question, and for the purposes of a scientific
paper like this, it is not necessary to concoct a story of how it evolved,
nor stuff the facts into a naturalistic tale of origins.
Science did not grind to a halt just because these authors omitted
an explanation for the origin of chloride channels. On the contrary, it
is the belief that there is design (information adapted to function)
in the world that has propelled science forward, and continues to do
so today. That is why Intelligent Design is good for science.
Scientists do well
when just uncovering amazing examples of intelligent design like this one.
Evolutionary storytelling is forced, incredible, superfluous.

Public School Enforces Mandatory Islam Course; Casts Christianity in Negative Light 01/15/2002
Many news sources have been reporting the Byron, California school district that started requiring 7th graders to take a three-week
course in Islam, including reading the Koran, studying the important figures of the faith, wearing a robe, adopting a
Muslim name and role-playing their own Jihad. The textbook for the course, adopted by the California school
system, presents Islam in a very positive light, omitting any references to its massacres and mistreatment of
women, but casts Christianity in a negative light, highlighting Salem witch trials, crusades and inquisitions in
bold type. According to the ASSIST News Service echoed on the American
Center for Law and Justice site, a Christian teacher in the district complained that We could never teach Christianity like this ... We cant even
mention the name of Jesus in the public schools, but ... they teach Islam as the true religion, and students are taught about Islam and how to pray to Allah. She was dumbfounded to see that Islam is in at the same time the school system requires that she teach evolution in her science class with no reference to creationism or any contrasting viewpoint to Darwins theory. The American Center for Law and Justice has written a letter to the California school district demanding they allow students
to opt out of the mandatory course. See also the write-ups in the
Washington
Times and at
Pacific
Justic Institute. January 16, WorldNetDaily
dug up more detail about the Islam curriculum, the angry reaction of
some parents, the schools rebuttals, and the textbook contents, and
claims the Byron school incident is nothing unique.
OK, ACLU and People for the American Way, show your honesty,
integrity and impartiality. Here is a clear violation of separation of church and state. Show us
the same zeal with which you go after Christians who want to pray at a football game or mention creation in
a science class. We cant hear you . . . .
Learning about Islam would be fine, but this course advocates the religion
behind the September 11 attacks while denigrating the faith of Americas founding fathers.
Just when you thought you heard everything . . . According to Jay Sekulow of the ACLJ
(not to be confused with the ACLU), the class requires students to pray in the name of Allah the
Compassionate the Merciful, to chant Praise to Allah, Lord of Creation, to pretend
they are Muslims, wear Muslim clothing to school, stage their own Jihad, and select a Muslim name from a list to
replace their own name. Wont
junior high students love practicing jihad on one another. What are we trying to do, raise a whole generation
of John Walkers, to destroy our country with our own crop of terrorists? Come on, National
Center for Science Education, to the rescue! They uttered that horrid phrase Lord of Creation!
Come on, Americans United for Separation of Church and State: lets see some consistency here!
Come on, ACLU, PAW, NCSE, and all: people
might start suspecting your hostility is directed only at Bible-believing Christians, and blow your cover!
If any reader has doubted that there is a massive war of worldviews in our culture,
this story should clinch it. We already have the gay activists with free reign, teachers passing out
condoms and counseling abortion without parental knowledge, and witches in the schools. Whats next, a class on compassionate cannibalism, complete with an assignment to roast and eat your own arm (or that of a fellow student), or a required course in suicide with homework to kill yourself, or a required course in terrorism with an assignment
to blow up a building? What will it take to get Americans up in arms enough to stop this out-of-control education establishment, to realize that all that is required for evil to triumph is for good people to do nothing?

Microbes Fight Each Other in Perpetual Chemical Warfare Games 01/15/2002
A paper on theoretical biology in the
Proceedings
of the National Academy of Sciences tries to figure out why there
are so many different kinds of one-celled organisms. If the
environment they live in is the same, why so much diversity?
This is called the paradox of the plankton, which
seems to defy evolutionary logic. Should not the most diverse
environments give rise to the most diversity of species?
To study this paradox, three European geneticists
used a computer model and game theory to postulate that a modified
scissors-paper-rock game (a spatially explicit game theoretical
model with multiply cyclic dominance structures), seems to
suggest that antibiotic interactions within microbial
communities may be very effective in maintaining diversity.
In other words, there is a constant state of chemical warfare going on;
one species will invent a toxin that kills off rivals, but finds itself
bankrupt from the cost of production, giving an immune species a
chance to grow. Meanwhile, a fast-reproducing but not immune
species swamps the population by sheer numbers, only to be decimated
by the next chemical bomb. Or something like that.
Cute theory, but lets think
this through. Obviously the microbes are not consciously playing
war games. The only way game theory applies is by
coincidence of effects. If kids playing games in the playground
generate the same sound waveform as a flock of ducks, then you could
claim the two causes are analogous in some way; but if you really
believe the ducks are playing dodgeball youre carrying it
too far. The authors observe that many microorganisms give off
toxins, and that biodiversity among microorganisms is high, and yet
populations are dynamically stable. So they invent a computer
game model that produces the same effects between K (killers)
R (resistant strains) and S (sensitive strains with high birth rates).
They tweak how fast new toxins arise, how much species can share their
immunity genes, how resistant the enemy is, and all kinds of parameters:
Depending on the rates of the evolution of novel toxin, resistance
systems, and of their transmission between strains relative to the rates
of genetic diversification in other traits and of speciation, different
interpretations of the model strains are possible. It sounds
kind of like a game of Calvinball.
Putting in generous evolutionary assumptions and preventing any one
group from declaring Winner take all!, of course they get their
model to work. They wouldnt publish in PNAS if it were a
dismal failure. Does it indicate anything about real life?
Does it advance the theory of evolution? You decide.

How Fast Do Genes Mutate? 01/15/2002
Two Arizona State biologists examined a large number of genes
from many different mammals to estimate how fast genes mutate.
Writing in the
Proceedings of the National Academy of Sciences, they came up with
a result of 2.2 x 10-9 mutations per base pair per year
(i.e., a probability of about two mutations per billion years at a
given spot on the gene), much smaller than earlier estimates.
Also, contradicting a widely held notion, they conclude that mutation
rate is largely independent of generation time (number of years between
generations), implying that humans and mice genes mutate at the same
rate even though mice give birth earlier and more often.
This paper is an example of why you
cannot just accept the conclusions without studying how they arrived
at them. In the paper, they assume evolution, and employ their
assumptions of how long ago different lineages separated as part of
their calculations. They also make judgment calls about which
genes are best to compare and which are not. They arrive at
conclusions that differ with their other evolutionary colleagues.
Looking at the size of the tweak space, its hard to feel
satisfied that anything real has been discovered in their analysis

Evolution Advocacy Group Targets Churches 01/14/2002
In an effort to help churches understand that evolution isnt such a bad thing, the National
Center for Science Education, an organization whose sole purpose is to to keep evolution in the science
classroom and scientific creationism out, has prepared a
Congregational
Study Guide for Evolution, based on the
PBS TV series Evolution
which aired last September across the country. The study guide tries to help pastors
and congregations think about each episode with questions like, Consider some of
your favorite hymns and prayers that speak of creation. How might they better reflect an understanding
that is informed by, not opposed to, evolution?
Its not enough that NCSE has to fight creation science
tooth and nail alongside the ACLU in every public school where criticism of Darwin raises its
meek head, now they have to send their smart bombs right into the church doors in a
pre-emptive strike. The quote above is from Episode Five, the infamous Why Sex?
episode that basically taught that any and every sexual escapade you want to commit is
justified by evolution. The misnamed National Center for Science Education is not a scientific organization,
nor does it care about the quality of science education; it is an
advocacy group committed to fighting its declared enemy Bible believers. (Other religious
people are no threat to their power base; see Episode Seven What About God?). NCSE has all
the trappings of a political action committee.
Here at Creation-Evolution Headlines we scour the top scientific journals for
the best possible sources, searching in vain for real evidence for evolution, and reporting their anomalies
in their own words, with links to the original papers so you can check the facts for yourself. NCSE and PBS,
however, were very selective about their spokesmen on the TV series. They generously quoted Kenneth Miller,
who has no problem compartmentalizing his
brain into mutually exclusive halves, with mindless, purposeless evolution on one side and divine design on the other, but
would not allow one word from critics of evolution, many of whom are not even Christians or religious
at all. On top of that, they put happy faces on some of the worst Christian-bashers and creation-bashers,
making sure they did not say what they really believe on camera. They ignored the worst criticisms
of evolution and the weakest areas of the theory, focusing instead on tales woven out of miniscule data,
glued together with computer graphics. Phillip Johnson, speaking of similar deliberate deception
on the part of the National Academy of Sciences about the real impact of evolution on religion, explains the strategy:
The National Academys way of dealing with the religious implications
of evolution is akin to the two-platoon system in American football. When the leading figures of
evolutionary science feel free to say what they really believe, writers such as Edward O. Wilson,
Richard Dawkins, Daniel Dennett, Carl Sagan, Steven Pinker, Stephen Jay Gould, Richard Lewontin
and others state the God is dead thesis aggressively, invoking the authority of science
to silence any theistic protest. That is the offensive platoon, and the National Academy never
raises any objection to its promoting this worldview.
At other times, however, the scientific elite has to protect the teaching of the
fact of evolution from objections by religious conservatives who know what the offensive
platoon is saying and who argue that the science educators are insinuating a worldview that goes far
beyond the data. When the objectors are too numerous or influential to be ignored, the defensive
platoon takes the field. That is when we read those spin-doctored reassurances saying that many
scientists are religious (in some sense), that science does not claim to have proved that God does not
exist (but merely that he does not affect the natural world), and that science and religion are separate
realms which should never be mixed (unless it is the materialists who are doing the mixing).
Once the defensive platoon has done its job it leaves the field, and the offensive platoon goes right back
to telling the public that science has shown that God is permanently out of business.
(The Wedge of Truth, IVP 2000, pp. 88-89).
So dont believe for a minute this slick hype put out with the blessing of
an avowed atheist, NCSE head Eugenie Scott, that evolution has a wonderful consistency
with Christianity. Listen instead one of her spokesmen
on Evolution, Daniel Dennett, who described the theory of evolution as a universal
acid that eats through all traditional beliefs. Pastors, be on your guard! You are being
handed a corrosive potion with a sweet smile and instructions, Here,
drink this...its good for you. Did Paul warn the churches in Acts 20 and I Timothy 4 for naught?

The Color of Life on Europa? 01/14/2002
NASAs Astrobiology
Institute is holding out tentative hope that life could exist on
or near the surface of Europa, the icy moon of Jupiter thought to have
an ocean deep under the crust. They base this on spectra taken
by the Galileo Spacecraft that
seem to match the biological signature of extremophiles on earth.
...it could be that any number of possible microorganisms that may have evolved on Europa also produce the same sort of IR signature as bacteria
on earth, hopes Brad Dalton who studied the spectra. Im
as surprised as anyone, and Im trying very hard to be skeptical,
he adds. I am not claiming to have found life on Europa.
More work needs to be done.
So eager are astrobiologists to prove
we are not alone, that they will go to great lengths to draw hope out
of the meagerest data. Remember when all it took to start
speculation that Venus had dinosaurs was the presence of a dense
cloud cover (hence tropical climate, hence swamps, hence dinosaurs)?
Deja vu. Try a little harder to be skeptical.

Another Finch Story 01/14/2002
National Geographic
is excited about a finding that pet finches released in
Montana and Alabama have adapted to their new environments
with changes in body size in just 30 years, showing evolution on fast
forward.
(It was the Galápagos finches that became an icon
of evolution in Darwins theory. )
Most people think of evolution as a process that takes millions of
years, said evolutionary biologist Alexander Badyaev of Auburn
University in Alabama, who led the study. But here is an example
of real-time evolution in which two populations of finches developed
characteristics to match their new environments in just a few decades,
he added.
The original paper is in the Jan 11 issue of
Science,
which also contains this summary by
Elizabeth
Pennisi.
This classic case of
equivocation tries to associate
variation (which evolutionists and creationists both accept) with
evolution (which only Darwinists accept). Everybody knows there
is a lot of variation built into living things: just look at dogs!
Finch body size, beak size, egg size etc. are not evolution in the
usual Darwinian sense of molecules to man. These are still the
same species of finch. When we watch them evolve into mammals,
then we will be impressed. Actually, the speed of this adaptation
should alarm evolutionists; if evolution takes place this
quickly (decades instead of millions of years), then where are the
billions of transitional forms that we should see in the fossil record?
The authors state, Thus, the proximate mechanisms
that allowed house finch populations to become established in two
distinct environments and to respond so rapidly to local selection are
not known. They theorize that females might be able to
control hatching order and egg size, but they arent sure about
that either, and how could a dumb bird care? All this crowing
about evolution in the headlines is hardly a feeble chirp in the
text of the paper.

Etched Lines in Rocks Show Early Man Used Abstract Reasoning 01/11/2002
SciNews
says Modern Behavior Emerged Earlier Than Previously Thought
based on the finding in a South African cave of regular etched lines in
rocks thought to be 77,000 years old, written in ochre by early modern
humans. This more than doubles the previously believed piece of
evidence suggesting abstract thought, which is estimated at 35,000 years
old. According to
Nature Science
Update, these could be considered the oldest works of art.
The evolutionary anthropologists
timeline stretches credibility. If anatomically modern humans
have existed for 100,000 years or more, fifteen times longer than all
recorded history, why did they not develop language and art, cultivate
crops, ride horses and build cities in all that time? Instead,
human civilization just bursts on the scene fully formed in the Fertile
Crescent, with commerce and language and mathematics already established
from the beginning. And why didnt the population bomb
hit 90,000 years ago? Something is drastically wrong with the
dating methods. Throughout history there have been recluses who
lived in caves and made markings; there are some today (hippies).
All these findings could be dated more recently using different assumptions.
It is only the Darwinist mentality that has to force observations into
a primitive-to-complex sequence; the actual evidence suggests the abrupt
appearance of human abstract thought and culture. Whether the
universe, stars, planets, life,
plants,
animals, or
humans, we see abrupt appearance everywhere.
This is not evolution.

Radio Message 01/11/2002: Teaching the Controversy.
In his weekly broadcast In the Public Square, Phillip Johnson comments on
the Education Bill recently passed by Congress:
The most important thing about the Education bill that President
Bush recently signed may be something the newspapers arent telling
you. The Committee Report on the bill contains the substance of an
amendment introduced Senator Rick Santorum and passed in the
Senate by a bipartisan 91 to 8 majority.
The Report says that where controversial subjects such as biological
evolution are taught, the curriculum should help students to
understand the full range of scientific views that exist, why such
topics may generate controversy, and how scientific discoveries can
profoundly affect society. Despite the panicky efforts of
Darwinist science educators to remove this language, the full Congress
has said that students should learn both sides of the controversy.
The Congress and the President have done their part, so it is up to us
to make sure that this new freedom to teach the controversy
becomes a reality in the classroom.

Galaxies Continue to Puzzle Theorists 01/11/2002
Writing in the Jan 11
Science,
Italian astronomer Francesco Bertola gives the current State of the
Universe Address, based on a discussions at a recent workshop by the
European Space Agency. There are still tensions between
dark matter theory and observed distribution of unseen material
inferred from the motions of galaxies.
Another ongoing lively debate among cosmologists
is whether galaxies formed in a monolithic collapse
soon after the big bang, and have been aging peacefully ever since, or
whether they formed from hierarchical merging of smaller
galaxies throughout the lifetime of the universe (i.e., top-down vs
bottom-up). A third controversy concerns the Tully-Fisher relation,
which relates galaxy brightness to maximum velocity of rotation.
Plots for distant and nearby galaxies have different slopes, and
intersect for the most massive galaxies. According to Bertola,
This observation may indicate that the most massive galaxies
evolved little during the past 10 billion years. In contrast,
the less massive ones seem to have undergone a remarkable loss of
luminosity during the same period. Explaining this result constitutes
a challenge for different models of galaxy evolution.
When Edwin Hubble made his famous
tuning-fork
diagram of galaxies in the 1920s,
astronomers
disagreed about which direction on the fork galaxies evolved.
Now, 75 years later, with the Hubble Space Telescope and a golden age of
instruments, they are still asking the same question. The recent claim by
NASA (see the January 8 headline) of a gigantic
burst of starbirth and galaxy formation in the early universe lends
credibility to the model that they were fully formed at the start, and
have been aging ever since, with a few collisions and mergers
along the way.
We have been reporting stories that
dispute the concept of dark matter,
but cosmologists depend on the unknown, invisible stuff, whatever it is.
For evolutionists, dark matter plays the role
of Skinners Constant that quantity which, when added to,
subtracted from, multiplied or divided by the answer you got, gives
you the answer you should have gotten.

Cosmogenic Radionuclide Dating Finds Surprises 01/11/2002
Science magazine Jan 11 has
a status report on the progress in cosmogenic radionuclide dating.
The method takes
advantage of the fact that cosmic rays only penetrate about a meter
into the rocks, and when they do, some collide with nuclei to produce
rare radioactive isotopes. More of these isotopes should accumulate
on the surface than at depth. As mountains erode, it should be
possible to infer the erosion rate. This technique
is in its youth, but has already uncovered some surprises:
- Estimates of erosion rates in some Idaho mountains were 17 times
higher than expected (see our June 26
headline) implying that catastrophic events occasionally swamp
uniformitarian observations.
- An ice sheet in Kentucky arrived 700,000 years earlier than previously
thought.
- Climate appears to have no effect on erosion rates, which is odd,
because the process is called weathering.
- Cultivation of land appears to increase erosion up to 100-fold.
The technique requires choosing sample sites carefully, and because of the
cost, You dont have the luxury of trying to test alternative
interpretations rigorously, one researcher says.
Like every other method of dating the
unobservable past, this one requires faith in untestable assumptions.
You can measure how deep an average cosmic ray can penetrate today,
and you can measure the radioactive decay rate of a radionuclide today,
and you can measure the amounts of these nuclides in selected sample
sites: thats it the rest is all inference. No one
knows if the cosmic ray flux is constant (see yesterdays headline about
supernovas, which suggests periods of intense
bombardment). No one knows the rate of catastrophic events.
Even the selection of sites depends on assumptions about which sites are
better than others. When they get differences of 1700% between
theory and observation, and other surprises, its hard to have
any confidence at all in any of the other claims.

Supernovas May Have Blasted Life to Extinction, and Helped
Life Evolve 01/10/2002
Three astronomers speaking at the annual meeting of the American
Astronomical Society believe the earth was nearly sterilized by
supernova blasts from the past. According to the
University
of Texas at Austin (alma mater of one of the researchers), the solar
system has been subjected to several nearby supernova explosions.
(Johns
Hopkins astronomers think they have found a candidate that exploded
close to our sun two million years ago.)
Mars, with its thinner atmosphere (at least recently)
would be unprotected from the sterilizing influence of the blast.
Supernovas and strong solar flares could bathe the earth and Mars in
gamma rays for extended periods, causing high mutation rates and massive
die-offs, but also ... the challenging mutational radiation
environment would accelerate the evolution of life.
Once upon a time, a large army found itself
surrounded by enemies with machine guns. The machine gunners mounted
a sustained and relentless attack, killing off 99% of the hapless
victims. But just by chance, one soldier was hit in a one in a

his wife gave birth to Superbaby. Send us your

Is It Against the Law to Find Flaws in Evolution? 01/09/2002
The Minneapolis Star Tribune reported
that the Supreme Court declined to hear the case of high school biology teacher and coach Rod LeVake,
who was reassigned from teaching biology for saying that he had problems teaching evolution as fact.
He did not want to teach creationism or religion in class, but only wanted to mention flaws in the theory of
evolution. The
ACLJ attorney said, Were disappointed. ... I dont think either of the lower courts
really understood the case; the district turned it into something it never really was.
[LeVake] didnt want to do much beyond saying there are scientists out there
that criticize evolution on scientific grounds, and nothing more. I think the
district decided he was a stealth creationist.
Update 01/15/2001:
Answers in
Genesis reports that according to a new poll,
public school students still want creation taught.
In response to the LeVake story,
Channel
One polled students on which views they wanted taught in science.
Just 17% wanted evolution only,
31% wanted creation, and 52% wanted both views taught. That adds
up to 83% of public school students wanting creation included in the
science classroom.
Stealth creationist hows that for
loaded words and fear
mongering? Are you shocked at this? Teachers in Russia have more
freedom to criticize Darwinism now than they do in America. LeVake did not want
to bring religion into the science class; he just
wanted to present scientific facts that dont
support Darwinism. Such evidence is being published in
science journals all the time; read about it here on these pages. Besides, the
Congress just passed an education bill that encourages
schools to present a diversity of views on controversial subjects like evolution, and
LeVake is trying to be obedient. But so paranoid are the Darwinists, they cannot
allow a calm discussion of the evidence, they have to invoke scare tactics and use raw
power to force indoctrination of their view of origins, even when the evidence
is against it. Stealth creationist good grief, as if he snuck in from
Afghanistan. Sooner or later people are going to realize that if evolution has to be
force-fed to students it must be bad medicine. We can only hope Phillip Johnson is right:
If the situation is as I
have described it, the intellectual bankruptcy of Darwinism cannot be concealed for very
much longer. The Darwinists may delay the day of reckoning for a while by wielding
the weapons of power, but more and more people are learning to press the right questions
and to refuse to take bluff or evasion for an answer. (The Wedge of Truth,

Biology of the Future: Molecular Machines 01/09/2002
With the Human Genome Project a recent memory, the cutting edge now
is the Human Proteome: the map of all the proteins and enzymes in the
cell, how they fold, how they work, and how they interact.
Two large teams of European scientists publishing in
Nature
have sequenced a third of the proteome of bakers yeast, which
they claim is on the same evolutionary branch as humans. Out of
20,000 proteins they sorted through, they were able to identify 17,000.
Most of these have functions that are unknown, and there were many
duplicates. So far, they were able to map the interactions of
1400 proteins, and found that proteins are very sociable and interact
in many and complex ways. They also discovered
232 multi-protein complexes and 134 new molecular machines,
98 of which were previously unknown. It appears that simpler
machines can combine into more complex ones, and be dismantled for
other uses. Said one researcher, It was a big surprise
how social these proteins are ... The whole cell is organized in a
way we were not prepared for. Another commented,
It defies the imagination. The human proteome is
estimated to contain at least 30,000 proteins. For the
full paper in the Jan 10 Nature,
click here (subscription required).
See also this summary of their work in
EurekAlert.
Another article in the same issue discusses the
ongoing investigation of how myosin, a molecular motor, moves.
Full text of original paper.
The summary uses the word
machine 17 times, yet ascribes all this engineering to
evolution. How much longer must we be subjected to an
outworn paradigm that is insufficient to produce the effects?
Machines do not arise from randomness, especially thousands of them
in a brainless yeast cell. Evolutionary
theory extrapolates
minor observed changes into major engineering feats it is profoundly
ill equipped to handle. Some of the most advanced molecular
machines are found in the simplest, supposedly most primitive,
one-celled organisms. When you ask them how a cell could invent
machines without intelligent design,
they give evasive answers that they hope to figure it out some day.
If they were to be held as accountable as your financial adviser,
you would fire them for such lame answers.
For a fascinating yet frustrating look at the
new biology
of molecular machines, read Bruce Alberts 1998 paper in
Cell,
The Cell as a Collection of Protein Machines: Preparing the
Next Generation of Molecular Biologists, in which he stands in
awe of the complexity of protein machines but then ascribes it all to
chance (evolution). Alberts, the President of the National
Academy of Sciences, begins by saying, We have always
underestimated cells, and talks about how simple the cell
seemed when he was a naive graduate student. Now, he says:
But, 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. Proteins make up most
of the dry mass of a cell. But instead of a cell dominated by
randomly colliding individual protein molecules, we now know that
nearly every major process in a cell is carried out by assemblies of 10
or more protein molecules. And, as it carries out its biological
functions, each of these protein assemblies interacts with several
other large complexes of proteins. Indeed, 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.
He describes proteins that act like
motors, assemblers, proofreaders and clocks, and waxes eloquent about
the elegance and efficiency of these vanishingly tiny machines:
We have also come to realize that protein assemblies can
be enormously complex. ... [describing one example, the spliceosome]
As the example of the spliceosome should make clear, the cartoons
thus far used to depict protein machines (e.g., Figure 1) vastly
underestimate the sophistication of many of these remarkable devices.
Then he proceeds to speculate on how they might have evolved, thinking
DNA transcription seems to be more primitive than replication, but
refers to evidence that undercuts his speculation: However,
the argument has certainly been weakened by the unexpected complexity
of DNA transcription processes in eukaryotes, which I would have
predicted to mimic DNA replication in their elegance and their
simplicity. Alberts concludes that we have a lot to learn and
that the future of biology rests in understanding proteins as
molecular machines.
So if you want to be on the cutting edge,
you need to know this: no longer is the cell to be considered a squishy soup of
funny-looking stuff. It is the most complex, efficient, organized
automated factory we have ever seen, composed of systems and subsystems
and interchangeable parts, working at lightning speed, rarely making
an error, its cargo zip-coded and transported on bullet trains,
building and recycling thousands of structures continually, powered by
proton generators, mastered by a central blueprint library, more
complex than a city yet
all this in a package so small, it is invisible to the human eye.
Stand amazed and wonder.

Biomimetics Looks to the Crayfish for Robot Ideas 01/09/2002
The science of biomimetics, or the imitation of natures designs, has some
University
of Melbourne scientists studying an Australian crayfish for ideas for
new Martian robot rovers. Though impressed with the motion and sensing
capabilities of the little animals, especially their
parsimony, that ability to control complex behaviours with an
amazingly small amount of brain power. Biomimetic engineers
hope to reverse-engineer some of these capabilities, such as the crayfishs
feedback system for controlling complex movements that would delight
any engineer. But he attributes these engineering feats to time and chance:
Evolution doesnt always come up with the
best solution from an engineers perspective. ...
Evolution does not necessarily produce an engineers solution
to an animals problem. It simply produces one that works, one
that is selected because its features give the individual an edge -
even a slight one - over its competitors in the game of survival.
Biomimetic researchers also need to be aware that animals carry design
features that reflect their evolutionary history as well as
responses to their present situation. When we dissect them we may
find features and solutions that appear inefficient or counter
intuitive. The human appendix is one example of this.
Hey now, lets think this through.
You are impressed enough with this technology to reverse engineer it,
yet you attribute it to blind, impersonal, unintelligent forces?
Then why not use blind, intelligent forces in your engineering and see
if you can improve on it, or come up with something so compact,
lightweight, efficient and functional from scratch?
And how can you use the phrase design features when
evolutionists reject the inclusion of intelligent design as a cause?
Stick to your own vocabulary: purposeless, undirected, random, pointless.

to whether the human appendix is an inefficient or counter intuitive
device.

Take a Deep Breath: Early Atmosphere Had Abundant Oxygen 01/09/2002
Three geologists claim to have found evidence for the presence
of atmospheric oxygen in rocks 2.7 to 3.5 billion years old,
claims the
Commonwealth Scientific and Industrial Research Organisation of
Australia. They have found pisoliths and sulphates that could
not have formed without an oxygen-rich atmosphere. If true, this
pushes the appearance of oxygen back to the very beginning of earths
atmosphere; Their theory challenges long-held ideas about when
the Earths atmosphere became enriched with oxygen, and pushes the
likely date for formation of an atmosphere resembling todays far
back into the early history of the planet. It may also
revolutionise [sic] the worldwide search for gold and other minerals,
and raises new questions about when and how life could have arisen.
Their paper is published by the Society for Economic Geology.
They claim that the primordial air may
have been breathable. Note that this is before
life evolved, contrary to conventional wisdom that it was life that
gave rise to atmospheric oxygen. If this new claim hold up,
its all over for chemical evolution.
Oxygen is poison to the alleged building blocks of life.
We do not accept the dates,
but just point out that claims made within the evolutionary paradigm
are self-incriminating. If the earth always had atmospheric oxygen,
as more and more geologists admit, then all the Miller-experiment
pictures and primordial soup scenarios youve seen in textbooks
have been falsified.
Parents: print the news story out, hold it
side by side with your childs science textbook next to the diagram
of the Miller experiment, and demand that this kind of contrary
evidence gets mentioned.

Universe Began with Fireworks Grand Finale 01/08/2002
At a NASA press conference
January 8, a bombshell announcement was made that
could have numerous ramifications across all of astronomy: the
grand finale came first. A huge burst of starbirth occurred
early in the universe, just a few hundred million years after the
big bang. From the very beginning, things were faster and
brighter, judging from infrared studies of the deepest galaxies
studied by the
Hubble
Space Telescope.
Lead astronomer
Ken
Lanzetta of State University of New York
deduced the early starburst by inferring a 3D map of the
Hubble
Deep Field, the famous 1996 image of the farthest and faintest
galaxies. He inferred distances from the color, assuming
redshifts as distance indicators and taking into account absorption
by intergalactic hydrogen, the expansion of space-time and other factors.
Lanzetta concludes that 90% of the light from the early universe (mostly
ultraviolet) is missing.
The idea that the fireworks ran backwards, according to
Dr. Bruce Margon of the Space Telescope Science Institute, is
not at all intuitively what one would have predicted.
Although they are still married to
the big bang theory and its attendant timescales, their announcement
has to be grievous for naturalistic cosmology. It seems to
compound the lumpiness problem many-fold. They are pushing the
formation of stars and galaxies into the first
5-8% of the assumed age of the universe, and saying
everything was fully formed as far back as it was possible to
imagine, and that there
were 10 times as many stars forming in the distant early universe as
there are today. Compounding the problem is that all known stars
have heavy elements, implying they are second- or third-generation
stars.
This announcement is bound to have a ripple effect on
theories of dark matter, galaxy formation, star formation, planet
formation practically everything else in astronomy.
Of course it must be remembered that their measurements
are at the bleeding edge of the possible, and built on many questionable
assumptions. The point of this story is that here, again, is a
major upset to conventional wisdom about cosmology. Even within
their own community, things are in turmoil as a result of this
announcement. Is it reasonable to expect that our knowledge
is improving, or instead, needs a major paradigm turnover?
How long must we trust the people who keep
coming to us and saying, Everything you know is wrong?
Is this progress, or are we being led down the primrose path from mirage
to mirage, like Coronado, whose Indian guide kept telling him the Seven Cities
of Cibola are just over the next hill, then the next, ad infinitum?
Dr. Margon admitted emphatically that the Holy
Grail of astronomy, finding pure hydrogen-helium stars,
has still not been found, even though they have been
saying for a century that the solution is just 3 to 4 years away.
There are no good candidates and maybe there arent
any. It is a theory without evidence.
The only explanation they could suggest was that all the first stars
were high-mass and went supernova quickly, seeding the second generation
of stars with elements heavier than the hydrogen and helium produced by
the big bang. Or, Dr. Margon jokingly admitted, if one wanted to be
a mischief maker he could just claim our whole theory is
wrong. Stand up for your right to be a mischief maker and
not take bluff or evasion for an answer (as Phillip Johnson
encouraged).
Also, Dr. Lanzetta admitted that star formation is so poorly
understood, it is always an ad hoc assumption that has to be adjusted
in any model of cosmology. (Whoa! We used to be told that
star formation was the best-understood thing in astronomy!)
They claim that this finding shows there was no slow,
gradual, childhood-through-adolescence evolution of stars and galaxies,
but that the universe looked mature as far back as we can see.
That sounds remarkably like what creationists believe; God formed a
fully-functioning, mature universe
in the beginning. With news of
this type, however, dont be surprised if other astronomers argue
that Lanzettas findings are all wet. Or, they can just
re-tweak all their variables and claim its not a problem, or
invoke Finagles Second Law.
And even these astronomers hedge their bets with the idea that the only
we can know for sure is with bigger and better telescopes ($$$).
If nothing else, we
learn from this announcement to have a healthy skepticism about the ability
of naturalistic astronomers really know what is going on out there, and
to take popular TV documentaries and their computer animations with a
grain of salt. One of the panelists recalled a popular university
joke, If we knew what we were doing, it wouldnt be called
research.

Ancient Cells Proofread Better 01/08/2002
Four biochemists from Stratagene in California, writing in the
Proceedings of
the National Academy of Sciences, have identified a
complex proofreading enzyme that improves DNA copying
accuracy up to 100-fold.
The enzyme is composed of multiple protein chains and can survive high
temperatures (around 200oF).
Although with this proofreading enzyme copying is slowed down (550 nucleotides
per minute instead of 2,800 without the proofreading), the fidelity
is greatly increased. It apparently works by breaking down a
product called dUTP produced by other construction pathways. dUTP
can poison a replicating DNA chain by substituting uracil. All living
things contain a suite of proofreading enzymes, including
members of this family of enzymes (dUTPases) that read ahead
and find dUTP to cut it out of the growing DNA strand.
But this one is not only highly effective, it works at
high temperatures. The surprise is that this bulky, complex
enzyme was found in a single-celled organism of the kingdom Archaea
(ancient ones) which includes bacteria that thrive in hot
springs.
This paper demonstrates that it is a
serious injustice to label one-celled organisms primitive.
They may be small and unicellular, but they are not primitive. In
fact, they appear to have superior engineering in many ways (notice that
this enzyme works a lot faster than a human typist!).
Astrobiologists frequently talk about extremophiles (organisms that can
tolerate extreme environments like hot springs, high salt, cold Antarctic
ice and deep sea vents), as if they demonstrate that life is easy to
evolve on other planets. Their name Archaea imply that they
are ancient, primitive organisms. A better paradigm is to view these
organisms as over-engineered so that they can adapt to special situations,
similar to how a race car engine, designed to push the envelope
at higher speeds and temperatures, is superior to your sedan.
Just think for a moment about the amazing fact (discovered
in our lifetime) that living things have editors and proofreaders!
Many word processors today include automatic spell checkers; would anyone
believe for a moment that Microsoft Word XP was a result of impersonal
trial and error? Now that we observe superior hardware and software
engineering in the living cell, the time is come for scientists to abandon
their allegiance to the untenable philosophy of naturalism, and face the music:
intelligence is an indispensable causative factor in the life sciences.
Note: Several other papers on DNA proofreading can be found in the
January 8 preprints of PNAS,
each equally interesting and amazing, such as this paper by biochemists
at the University
of Washington on nucleotide excision repair (NER), the ability of
enzymes to repair breaks in DNA caused by ultraviolet light damage.

Evolution) did an about face after Congress passed a resolution on
science education policy. The resolution, which called on schools to allow a diversity of
viewpoints on controversial issues like evolution, was first strenuously opposed by the NCSE
when the Senate passed the Santorum Resolution last June. But now that the full house
overwhelmingly passed similar language in December, Scott is proclaiming it
as a victory for their side. West, a fellow of the Seattle-based

While they claim devotion to the scientific method, their defense of evolution has

DNA Damage Response Team to the Rescue 01/04/2002
Americans proudly hail the firefighters and cops that go to work when terror strikes,
but did you know your body has an even more heroic team that flies into action when
DNA gets damaged? Its called the DDR - DNA Damage Response team.
The hearty band of specialized enzymes can handle any contingency: broken strands, loose
ends, typos, kinks,
twists and numerous other emergencies. During complex operations like duplication
and translation, the DDR team has its P&P (policies and procedures) down pat, including
checkpoints and feedback mechanisms to ensure repairs are made quickly, or that irreparable
damage triggers the appropriate salvage and disposal operations. Writing in the
Jan 4 issue of Science,
a team of seven geneticists, biochemists and biologists have determined that no less than 23 separate
genes code for the DDR (and there are probably more). In addition, they noted
an extraordinary level of
conservation of molecular mechanisms in DDR pathways in all living things, from the
worms they studied to man. Many kinds of cancer can be traced to defects or mutations
in these genes, that leave the cell like a city without a fire department.
You have to feel sorry for poor evolutionists having to deal
with of discoveries like this day after day.
Dr. Lee Spetner described the DNA repair mechanisms as so
effective, they can reduce the error rate to one in 100 billion, the equivalent of one
typo in 50 million pages of text, the lifetime output of 100
professional typists! (Lee Spetner,
Not By Chance!, p. 39).
Dont let the Discovery Channel, PBS, or
any other slick Darwin agent pull the wool over your eyes about the origin of life from
nonliving chemicals, when evolutionary theory has to deal with such monstrous leaps of faith.
Instead, be surprised and thankful that your DDR works so well, so much of the time. These
systems, so vital and proficient, eventually cease when we
return
to the dust from which we came. But dust without
intelligent
design is insufficient to produce such marvels. If you are an evolutionist, wont you
consider Creation?

Visualize Martian Seas 01/04/2002
Dutch artist Kees Veenenbos has taken images from the Mars Global Surveyor
and rendered them with rivers and crater-shaped lakes, according to
Space.Com,
(see the websites slide show of the renderings). In some of the pictures
he adds colors suggestive of life. Of course no one yet knows whether
liquid water ever existed on the surface (these days it would freeze or vaporize),
but the article postulates that
Mars, if wet, was probably also rather violent. Scientists have
suggested that floods likely came in chaotic episodes separated by thousands
of years of relative quietude.
In a related story, the venerable Griffith
Observatory of Los Angeles, closing Jan 7 for a three-year renovation, gave its closing
planetarium show to record crowds Sunday on the subject The Oceans of Mars.
While the show presented both sides of the debate on whether water ever flowed on the Martian
surface, it included picturesque artists renditions of balmy, beachfront property on the now dry,
windswept planet, and described astronomers search for water around the rest of the solar system and
around other stars with the teaser that if water is found, life might not be far behind.
Fantasy works overtime in the absence of proof.

astronomers), it would have had to be a nearly pure hydrogen star;
however, no hydrogen stars have been observed. The authors begin:
Chemical elements heavier than lithium are
synthesized in stars. Such "metals" are observed at times when the
Universe was only ~ <10% of its current age in the intergalactic medium (IGM)
as absorption lines in quasar spectra. ... Hence, these heavy
elements not only had to be synthesized but also released and distributed
in the IGM within the first billion years. Only supernovae of
sufficiently short-lived massive stars are known to provide such an enrichment
mechanism. This leads to the prediction that the first
generation of cosmic structures formed massive stars (although not
necessarily only massive stars).
In the past 30 years, it has been argued that the
first cosmological objects formed globular clusters, supermassive black holes,
or even low-mass stars. This disagreement of theoretical studies might at
first seem surprising. However, the first objects formed via the gravitational
collapse of a thermally unstable reactive medium, which inhibits conclusive
analytical calculations. The problem is particularly acute because the evolution
of all other cosmological objects (and in particular the larger galaxies that
follow) depends on the evolution of the first stars.
Lacking observational evidence, the authors turn to their computers.
Although previous simulations show gas clouds fragmenting too quickly to
allow collapse into stars, these authors simulate conditions (assuming a flat
cold dark matter cosmology) that produce a massive stars in isolation fairly rapidly
(within 10,000 years), starting 100 million years after the Big Bang.
They discuss a number of problems and unknowns
regarding such parameters as magnetic fields, accretion rates, and angular momentum.
In their simulation, only one atom in a thousand makes it into the first stars.
In the same issue, Martin Rees
gives his perspective on the problem and proposed solution.
The first stars are a problem for cosmologists, comparable
to the first life for biologists: according to currently-accepted theories of
the origin of life, life emerged quickly too quickly for comfort.
A similar problem exists for the first stars and galaxies, called the lumpiness
problem too much structure too soon. In a universe of particles
flying apart, how could they combine into a dense object like a star? Readers
may find this model more or less believable, but it should be apparent that with
enough parameters to tweak, you can weave any story. Necessity is the mother
of simulation.

How Butterfly Wings Shine 01/04/2002
Three scientists writing for the Jan 7
Biological
Proceedings B of the Royal Society have studied the way butterflies can flash
a lot of color with just a little flick of the wing. Their abstract has pictures
that reveal how this and other optical effects are produced from remarkable
nano-scale architecture on the wing scales of the butterfly, affording colour
through a combination of interference and diffraction; mechanisms responsible for
colour in soap films and on compact disks. As a result the butterfly signals
with remarkably strong colour flicker using very minimal wing movement.
The same property exists in pheasant and peacock
feathers. How did these creatures figure out the optics, let alone the
aesthetics, of their brilliant colors? Remember, for natural selection to
explain it, every member of the population that did not have the optical engineering would
have to die (cost of selection). Yet coloration is not vital to the
organisms fitness; after all, some butterflies are dull in color.
Design is a more viable alternative.

Eagle Nebula Pillars Unveiled 01/04/2002
Astronomy Picture of the
Day for Jan 3 and Jan 4
features two images from the European Space Agencys
VLT-8.2m-Antu Telescope
in Chile. The Very Large Telescope (VLT), equipped with an Infrared Spectrometer
and Array Camera ISAAC, re-imaged
the M16 Eagle Nebula Pillars of Creation made famous by the
Hubble Space
Telescope in 1995. Now, viewing the pillars at longer wavelengths,
astronomers were able to look deeper into the small dark stems of gas which were
dubbed Evaporating Gaseous Globules (EGGs), assumed to birthplaces of stars.
Of the 73 EGGs, ESO found only 11 of them contained stars in this survey, but more
may lie undetected in dense gas impenetrable by the near-infrared wavelength used by
the instrument. It is also not clear which came first, the stars or the EGGs.
If stars are truly being born in the gas pillars, the ultraviolet pressure from bright
stars in nearby cluster NGC 6611 is eroding and evaporating the gas, depriving the
stars (and any emerging planetary systems) of material.
Note: the Jan 4 issue of
Science is devoted to
theories of star formation; it contains a
web
supplement.
As interesting and beautiful as these images are, it is
important to distinguish between the observations and the interpretations.
Astronomers and newscasters frequently use phrases like stellar nursery, newborn
stars, a star is born and the like, when all they are really seeing is existing
stars and gas being eroded in a destructive process. They admit that they are
not sure the stars were already present or formed because of compression of the gas
by the cluster. And despite their optimism, (The new VLT infrared image
shows that there is now firm evidence for the recent birth of stars in the Eagle
Nebula and that at least some of the Eagles EGGs are fertile, not sterile! -
emphasis theirs), the
ESO astronomers seemed a little disappointed that only one in seven EGGs had an
embedded star (so far). We might also ask, what about all the other stars in
the image that have no gas nursery near them, and how do bright stars form near
each other if they blow each others gas envelopes away? The NASA
Astrobiology
Institute, nevertheless, calls these Young Stars in the Pillars of
creation in support of their quest to explain the origin of stars and planets.
There is just too much we dont know to be so overconfident. Whether
stars are being born is theory, but that stars are dying (e.g., novas, supernovas,
erosion and depletion of material) is observable fact.

Stark Black Clouds Stand Out in New Hubble Image 01/03/2002
A new Hubble
Space Telescope image released today shows mysterious
dark clouds standing out in bold relief against a red starry background.
Known as Thackerays Globules in the nebula IC 2944, astronomers
still know very little about their origin and nature except that they
are associated with dense clouds of doubly ionized hydrogen, assumed to be
active star-forming regions.
In another Hubble teaser, the press has been alerted to
an upcoming announcement for Monday: New findings about starbirth
in the early universe findings that could overturn current theories
if verified will be presented in a Space Science Update at 2:00 p.m.

Astrobiology: The Next Generation 01/03/2002
A new report Signs of Life produced by a multidisciplinary
group of scientists has been released, according to
Space.Com.
The report is a compendium of findings and conclusions by the Committee on the
Origins and Evolution of Life of the National Research Council.
At a kickoff workshop in Washington DC in April 2000, the group of
astrobiologists had a vigorous discussion about tools for detecting life,
policies for protecting from contamination, and models for planetary
environments that might harbor life. Committee Chair Jonathan
Lunine of the University of Arizona at Tucson feels it is a whole new
ball game from that of the Viking missions to Mars in 1976; new
findings of life in extreme environments are encouraging scientists
that life might be more adaptable than previously imagined (although
the search is still focused on life based on carbon and water).
Additionally, the technologies to detect life have improved greatly
since the Viking era.
Ames Research Center will be hosting a big
Astrobiology
Conference in April with Lunine and other principal players.
But in an article Jan 4 on Science
Daily, Andrew Lawler describes how other planetary scientists are upset
at all the attention astrobiology is getting:
But astrobiology gets little respect from many traditional planetary scientists,
who see it more as a creation of Washington politicians than as a
legitimate research area. ... The complaint against astrobiology is that the
field is heavy on hype and light on results.
Are we selling packaging or content?" asks Sykes.
Briefings to lawmakers about the Europa mission, he says, leave them with
the impression that [the spacecraft] will capture caribou walking
across the ice. He warns that overselling astrobiology could be disastrous.
Nevertheless, astrobiology seems to be NASAs shining star.
Space.Com describes Lunine as feeling that the
key to success in life detection in the field is to try a range of
techniques that vary in their specificity and need for prior
assumptions about the nature of life.
Thus they guarantee job security for years.
In their optimistic discussions, one thing is sadly
lacking: a serious attempt to explain the origin of information.
Instead, they pounce on the logical fallacy that life in extreme
environments is evidence that life can evolve anywhere. On
the contrary, extremophiles possess superior engineering compared to other
forms of life, that allow them to live where they do. Until and
unless astrobiologists can explain how the high degree of order and
information in living systems could arise without intelligent design,
they are just chasing mirages.

Evolution Has a Speed Limit 01/03/2002
James W. Kirchner, geologist at Berkeley, thinks he has found a speed
limit to evolutionary diversification after extinction events.
In a letter
to Nature (03 Jan 2002), Evolutionary speed limits inferred
from the fossil record, he applied Fourier analysis
to timelines of
extinction and speciation based on the fossil record of marine
invertebrates. Although extinction appeared random,
the ability of ecosystems to recover
and diversify appeared to be constrained over short time scales (25Myr or
less). These results imply that evolutionary responses to
extinction events are constrained by intrinsic speed
limits, says Kirchner. It has been shown previously
that evolutionary responses to extinction events are delayed in time;
the current analysis shows that they are also strongly damped in
amplitude. He feels his results indicate that human-caused
extinctions could be long-lasting: If the continuing anthropogenic
extinction episode turns out to be comparable to those in the fossil
record (which is not yet clear), my analysis shows that diversification
rates are unlikely to accelerate enough to keep pace with it. Thus,
widespread depletion of biodiversity would probably be permanent on
multimillion-year timescales.
Science
Now reported the thesis favorably, but gave the last word to Smithsonian curator
Douglas Erwin, who says,
Im not sure that the analysis is sufficiently robust to
support the conclusions.
This is absurd. Kirchner is applying
physics to the history of life, as if biodiversity has a wavelength
or the fossil record has a spectrum. His whole approach assumes
evolution is true and assumes the geologic timescale is reliable.
But the geologic timescale is a classic case of circular reasoning,
pieced together and calibrated on the assumption of evolution.
All the jargon (Lomb-Scargle Fourier transform, Nyquist frequency, etc.)
is sheer bluff if his starting assumptions are wrong. This is as
crazy as finding patterns in the snow on a disconnected TV. He
partially admits it (at least for extinctions), saying, Whereas
the power spectra of extinction rates generally lie within the confidence
limits for random white noise, the power spectra of origination rates
generally lie well outside those confidence limits at wavelengths [sic!]
shorter than about 25 Myr. But there is no confidence in his
confidence limits if the calibration of dating
is off and the assumption of evolution is wrong. It is amazing
this kind of thinking gets published. It is no more valid than
the detailed horoscopes of astrologers (who, incidentally, have better
source data).

Liar, Liar, Face on Fire 01/02/2002
In a brief communication to
Nature 03 Jan 2002,
scientists from the Mayo Clinic have developed a new non-invasive tool to
fight terrorism at airports. They developed a heat-sensing
machine that distinguishes deceit in facial heat patterns.
The new high definition technology involves the measurement of the
heat patterns created by the face; these heat patterns change dramatically
with lying, especially around the eyes. For a summary, see
this entry on
EurekAlert.
Mark Twain used to quip that
Man is the only animal that blushes. Or needs to.
Blushing is the external manifestation of conscience, a spiritual
aspect of man, who is more than an animal by virtue of this and other
attributes. Those who ignore their conscience long enough, however,
lose
all sensitivity to it.
The scientists claim their device works on 80% of liars
tested. The other 20% must be so far gone, they
dont
even know how to blush.

What to Watch For in 2002 01/02/2002
Science
Now posted its crystal ball list of research areas to keep
an eye on in 2002. Stem cell research, with its political and ethical
overtones, heads the list. Also hot is research into the human
proteome, the protein counterpart to the genome. New giant telescopes
on the ground should see as well as the Hubble, and a networked data
avalanche is coming. The editors also expect more precision tests
of the constants of nature using new optical clocks.
Finally, better imaging technologies may allow
biologists to watch cellular processes and signaling in real time.
One didnt have to wait long for the
Wonders of Creation show to begin. The same day, the Proceedings
of the National Academy of Sciences contained several papers
highlighting the near-miracles occurring in the cell:
- Biophysicists
armed with new techniques
watched an enzyme named cytochrome c fold into its complex shape in
three distinct stages, all within 16 thousandths of a second. (Read
our May 3 headline to get an idea of what
a trick that is.)
- Another
paper in the same issue found that the organization of the retina of
the eye depends heavily on a complex nuclear receptor enzyme;
mutations in this molecule can cause blindness.
It begins with the statement,
Normal human retinal development involves orderly generation of
rods and cones by complex mechanisms.
- Two cellular
biologists found that dendritic cells regulate the bodys
powerful T cells (soldiers in the immune system), preventing them from
action until they learn to recognize the enemy. Thus they prevent
friendly fire accidents (autoimmune disorders), but sound the
charge when an invasion begins.
As the cell
continues to reveal its machinery, watch for more evolutionists straining
to fathom how all this complexity could have evolved. The article
mentions that there are at least 35,000 genes, but there might be
millions of proteins each a finely-crafted, intricate tool
in a symphony of coordinated interactions that make even the simplest
life possible. Creationists can expect to see continued reasons
to stand in awe of God for the new wonders just now coming into view.
