NCSE has now signed up more than 1,000 Scientists named Steve.

The National Center for Science Education has now signed up more than 1,000 scientists named "Steve." Here's the petition that all 1082 Scientist Steves have signed:

Evolution is a vital, well-supported, unifying principle of the biological sciences, and the scientific evidence is overwhelmingly in favor of the idea that all living things share a common ancestry. Although there are legitimate debates about the patterns and processes of evolution, there is no serious scientific doubt that evolution occurred or that natural selection is a major mechanism in its occurrence. It is scientifically inappropriate and pedagogically irresponsible for creationist pseudoscience, including but not limited to "intelligent design," to be introduced into the science curricula of our nation's public schools.

Kenneth Miller’s unrelenting attack on creationism

Kenneth Miller is a professor of biology at Brown University. He is also a widely published author (co-author of high school and college biology textbooks used by millions of students). He is also a practicing Roman Catholic who has served as an expert in several court cases concerning creationist school boards that have tried to muzzle classroom science. In his most recent book, Only a Theory: Evolution and the Battle for America's Soul, Miller makes an unrelentingly strong case against creationists of all stripes, including those who advocate "intelligent design." I did not realize the strength of the scientific case based upon the analysis of the genomes of human beings and other animals. How strong is it? It is at least as strong as the fossil record, arguably much stronger. I already knew a few things about the arguments based on genome analyses. For instance, I had often read that the genomes of chimpanzees and humans were 99% the same (or, at least, 96% the same). I also knew that all animals possessed Hox genes, essentially "toolkits for generating body form." Miller reminds us that "it is the same kit whether that animal is a honey bee, a fish or an elephant." The Hox genes prove "deep connections between animal groups." Miller points out that these similarities are even much more striking than Haeckel's (admittedly exaggerated) embryonic drawings. In fact, Haeckel "actually understated the evolutionary case each of these embryos possesses the same developmental toolkit, revealing both are common ancestry and the similarity of form and function produced by the workings of the evolutionary process." These profound Evo-Devo findings (the combination of development and the study of evolution) show that we "no longer need to make a distinction between the two types of change known as macro evolution and micro evolution. We don't need to attribute special mechanisms for large-scale changes. Evo-devo "reveals that macro evolution is the product of microevolution writ large." According to Miller, these should be "chilling words" to the ID crowd.

Flooded With Data

I had an urge to think through some implications of a world-wide flood, such as the one Biblical Literalists claim happened a few thousand years ago. Let's suppose that it happened, that the entire world was inundated all at once to cover the highest mountain, and that all surviving land animals and short-range birds were preserved in a single boat. What would the ecological landscape look like? gray worldFirst, all land animals would only be found on a single connected land mass. There is no way that any crawling creature could have reached Australia or the Americas from the Middle East. Most especially tropical animals. Secondly, we expect to see floral panspermia. That is, the waters would have carried every species of seed to every land mass all at once. Vanilla and cocoa and peppercorns should all be found growing in the same places throughout human history. Same for and chile peppers and coffee and potatoes. Wheat and maize should also be seen as combined staples of every ancient diet. Or the opposite: The flood waters killed off all the seeds except what was carried on the ark. Therefore, only the plants found in the middle east could exist anywhere in the world. Also, all modern animal species should be represented in every geological flood stratum. After all, a single massive drowning event doesn't distinguish between creatures of comparable size like an allosaur and an elephant or a trilobite and a mouse. Surely there must be abundant examples of these combined fossils. So it is easy to prove that such a flood actually happened. In fact, it must have been proven beyond a shadow of a doubt when Europeans first sailed to the Americas and found everything there to be just the same as back home.
