Brain Is Faster Than the Blink of an Eye
July 26, 2005
You blink about every 4-6 seconds, says David Burr in Current Biology,1 adding to over 17,000 blinks a day. Each time the world goes black for 100 to 150 milliseconds, as the eyelids attenuate the light a hundredfold. Why don’t we see the world like a flickering movie? We generally perceive an uninterrupted stream of […]
Life on Mars and Titan?
July 26, 2005
Life has not been found on Mars, but some scientists, according to National Geographic News, are worried that we are contaminating the planet with Earth germs that will make the search for Martians more difficult. Speaking of Mars, a report in Science Now claims that Mars rarely got above freezing in its entire history. […]
Do Butterflies Evolve Via Team Stripes?
July 25, 2005
A BBC News story is claiming that butterflies split into competing teams when differences in their wing patterns emerge. Based on a paper in Nature,1 this is supposed to be an example of a rarely-observed mechanism for speciation, called reinforcement: in this case, “These wing colours apparently evolved as a sort of ‘team strip’, allowing […]
What Is Really Known About the Genetic Basis of Evolution?
July 25, 2005
Now that the genomes of a variety of plants and animals have been published, is there a clear picture of evolution emerging? Sean Carroll (Howard Hughes Medical Institute) wrote a review in PLoS Biology,1 in which he explored the current thinking about the evolution of anatomy at the genetic level. The thing to watch for […]
Michael Ruse Balances the Scales in Creation-Evolution Conflict
July 22, 2005
Sahotra Sarkar seems in a bit of dilemma about how to treat Michael Ruse’s new book, The Evolution-Creation Struggle (Harvard, 2005). In his review of the book in Science,1 Sarkar knew that Ruse is an important ally in the fight against intelligent design (see 02/18/2003 entry), but he seemed a little bit put off by […]
A Day in the Life of an Evolutionary Biologist
July 21, 2005
Meet Dr. Judith X. Becerra. She is an expert on plants of Mexico. Her latest research strove to determine the rate of evolutionary diversification of a genus of trees with a name similar to her own surname: Bursera. These trees inhabit a range of biomes in the tropical dry forests of Mexico and are well […]
Lung Link to Dinos and Birds Disputed
July 21, 2005
Carl Wieland at AIG has given a creationist response to the widely-publicized claim last week that dinosaurs breathed like birds (see Live Science and News@Nature). Creationists are good for evolutionists. Otherwise, who would keep their rampant speculations in check? If evolutionists were really interested in truth, they would welcome debate over interpretations of evidence from […]
Bone Has Built-In Shock Absorbers with Molecular Springs
July 19, 2005
Your bones have little molecular springs in them that unwind and keep the collagen fibrils “glued” together when stress threatens a fracture. See the description, with electron micrographs and diagrams, in a press release from UC Santa Barbara. Said co-author Daniel Morse, director of UCSB’s Institute for Collaborative Biotechnologies: “It’s especially exciting for us to […]
Has Anti-Semitism Been Good for Jewish Evolution?
July 19, 2005
National Geographic News gave favorable coverage to a controversial theory by anthropologists at University of Utah that anti-semitism was a form of natural selection. The racism against Jews in Europe, while selecting for higher intelligence, also selected for certain types of diseases. Reporter James Owen did point out that not all anthropologists agree with the […]
Scopes 80th Anniversary Leads to Reanalysis
July 19, 2005
Alex Johnson, reporter for MSNBC News, has written a piece trying to set the record straight about the Scopes Trial of 1925. Often portrayed as a battle of science vs religion and a group of hillbilly hicks against enlightened intellectuals (the “Inherit the Wind” stereotype), the historical trial was much different, he demonstrates. William Jennings […]
First-Generation Star Claim Discounted
July 18, 2005
e first generation of stars, made of pure hydrogen, might have been detected, are now shown to be erroneous (this is an update on the 04/24/2003 entry). Iwamoto et al. in Science1 have shown that the two hyper-metal-poor stars are actually second-generation stars, seeded with heavy elements by supernovae. Timothy C. Beers (Michigan […]
School Evolution Bills Listed
July 18, 2005
In response to claims in the media that many states are passing bills to mandate the teaching of intelligent design along with evolution, Seth Cooper on the Evolution News blog has listed 10 states where evolution bills are being debated and three more where discussions are taking place in the legislature. Contrary to media reports, […]
Junk Cells Maintain the Brain
July 16, 2005
The most abundant immune cells in your brain are not the neurons, but microglia – spindly cells that were thought to be static and immobile, the smallest of the glia cells that were once considered mere scaffolding to support the more important gray matter (see 11/20/2001 and 01/29/2001 entries). When two scientists recently applied the […]
Sharks and Beavers Inspire Humans
July 16, 2005
Animals never cease to amaze us with their clever solutions to problems that plague human technology. EurekAlert told of work being done by the Society for Experimental Biology to emulate shark skin as a self-cleaning surface for boats; National Geographic News has pictures of the new product, and a comparison with shark skin. The navy […]
Tulsa Zoo Tolerates Religion – Except the Bible Kind
July 16, 2005
It’s OK to praise the Hindu god Ganesha and preach pantheism at the Tulsa zoo, but not to mention Genesis. The zoo board reversed itself after first agreeing to permit an exhibit of the biblical creation account, reported Agape Press. Christian supporters argued that the zoo “already features religious symbols in other displays, including a […]

David Coppedge, B.S. Education, B.S. Physics, founded Creation-Evolution Headlines in late 2000 as a way to share science news he was encountering at NASA. It has grown into a highly-trusted source of news and commentary critical of the pro-Darwin consensus, providing analysis of breaking news of interest to creationists and evolutionists, without the Darwin spin. He has authored over 7,000 entries at CEH since its inception.
