1400 Genes Essential to Grow a Fish
July 16, 2004
A team from MIT scanned the genome of the zebrafish and concluded there are about 1400 genes essential for embryonic and early larval development.  They did hands-on mutation experiments with 315 of these and found that mutations usually produced visible defects within 5 days that were invariably lethal.  Estimating that they had experimented on about […]

Earliest Bilaterian Fossil Claimed
July 14, 2004
Microscopic etchings in rock alleged to be primitive bilaterian fossils have been reported by J.Y. Chen et al. in China.  (Bilateria are organisms displaying symmetry along one axis.)  The report, printed in the July 9 issue of Science,1 dates the fossils at 40-55 million years before the Cambrian.  Erik Stokstad in the same issue2 calls […]

“Domesticated Computer Viruses” Demonstrate Adaptive Radiation
July 4, 2004
Lenski and Adami are at it again (see 05/08/2003 headline), attempting to demonstrate Darwinian evolution in the computer with “digital organisms” which they describe as ”domesticated computer viruses”  Their digital organisms are small computer programs with logic functions that can reproduce and respond to mutations.  They reward the ones that evolve with more resources (CPU […]

Ernst Mayr Recounts 20th Century Evolution Battles
July 2, 2004
apostle of Darwinian evolution, Ernst Mayr, turned 100 recently.  His mind still sharp, he recounted in the July 2 issue of Science1 the battles that led to “Neo-Darwinism” in the 1940s.  Surprising though it may be to some, there was no consensus on speciation, natural selection and other key evolutionary concepts for eighty years since […]

Biochemists Mutate Protein, Make a Catalyst
June 25, 2004
“Enzymes are among the most proficient catalysts known,” wrote three Duke University scientists, “and they catalyze a wide variety of reactions in aqueous solutions under ambient conditions with exquisite selectivity and stereospecificity.”  The team set out to rationally design their own enzyme.  Their work is reported in the June 25 issue of Science.1  Building on […]

Angry Evolutionist Seeks to Revive Peppered Moth Story
June 25, 2004
Michael Majerus has had it with creationists who leaped onto his 1998 book and used it for ammunition against Darwinism.  He had confessed that the simplified textbook story of the peppered moth was inaccurate, but he never meant to cast doubt on evolution.  Majerus (U. of Cambridge) is highlighted in a profile in the June […]

Cleaners Advertise in the Fish Market
June 22, 2004
The plot of this science project seems made for Disney animation, a fishy version of Aesop’s parable of Androcles and the lion.  There are fish that will clean parasites out of the mouths and gills of their predators without getting eaten (see 01/13/2003 headline).  How these “cleaner fish” and their clients developed this risky relationship, […]

Stickleback Fish Achieve Stardom in Evolutionary Labs
June 18, 2004
According to Elizabeth Pennisi in Science June 18,1 the three-spine stickleback is being studied in 100 labs as a model of evolution.  Over the last century, the little fish has been the subject of some 2000 papers, seven textbooks, and a Nobel prize-winning thesis.  Evolutionists have been attracted to this fish because it appears to […]

NASA-Ames Gives Darwin Credit for Antenna Design Project
June 16, 2004
A press release from NASA-Ames Research Center claims, “NASA ‘Evolutionary’ Software Automatically Designs Antenna.”  Using artificial intelligence software, their approach converged on the best design.  The article explains: “The AI software examined millions of potential antenna designs before settling on a final one,” said project lead Jason Lohn, a scientist at NASA’s Ames Research Center, […]

Darwinists Fight Over Niche Construction Theory
June 9, 2004
According to the Sacramento Bee last week, Roseville teachers who rejected the “Quality Science Education Policy” (see 06/04/2004 headline) did so because “there are no scientifically valid arguments against the theory of evolution.”  They must not be reading Nature.     In the current June 10 issue,1 three scientists say there has long been “vigorous […]

Worm Genes Show Non-Evolutionary Pattern
June 9, 2004
Biologists at New York University compared genes of roundworms to look for evidence of evolutionary ancestry.  What they found was not what they expected.  They found more genetic variation between outwardly-similar worms than between mice and men.  Their results were published online in PNAS June 7.1     The roundworm Caenorhabditis elegans is a model […]

The Evolution of Infidelity
June 7, 2004
The BBC News placed a sultry photo of a likely-undressed man and woman about to kiss alongside the headline of a story, “Genes may be to blame for infidelity.”  They report on the speculation by Tim Spector (Twin Research Unit, St. Thomas Hospital) that “if one of a pair of twins had a history of […]

Neural Darwinism: The Evolution of Truth
June 3, 2004
Can evolutionary theory build a bottom-up explanation of higher cognitive functions?  David Papineau (King’s College) doubts it.  In his review of The Physiology of Truth: Neuroscience and Human Knowledge by Jean-Pierre Changeux (transl. Malcolm DeBevoise, Belknap Press: 2004), published in the June 3 issue of Nature,1 he gives the author high marks, but concedes that […]

Darwinist Chides Recklessness of Evolutionists
May 31, 2004
The tendency of some evolutionists to engage in just-so storytelling was intolerable to George C. Williams, an influential Darwinian.  Throughout his life he called them to accountability.  Now elderly, he was recently honored by fellow evolutionists at State University of New York, Stony Brook.  Carl Zimmer described the event in the May 28 issue of […]

DNA: The Mystery of the Ultraconserved Elements
May 27, 2004
As we proceed into the age of genomics, the DNA codes of more and more animals are coming into focus.  The genomes of humans, chimpanzees, mice, chickens, dogs, rats and pufferfish have been sequenced so far, and more are planned.  Evolutionists expected the ancestry of all living things to be traceable in the genetic code […]
