In my previous post responding to the National Center for Science Education’s (NCSE) attacks on Explore Evolution‘s treatment of biogeography, I explained that there are many examples where there is inconsistency between evolutionary expectations of biogeography and plate tectonics. The NCSE is thus wrong to have claimed that “The consistency of these sorts of nested patterns cannot be explained without reference to common descent. The creationist ‘orchard’ is scientifically meaningless, since it makes no predictions.” * The classical “universal common descent” view is contrasted with the orchard model at below: The NCSE’s claim is perplexing because, as noted, the NCSE also claimed that “continuity [between biogeographic and evolutionary patterns] is what would be expected of a pattern of common descent, Read More ›

“Go to hell!” said Ron Numbers cheerfully to me, as we greeted each other at the front of Rockefeller Chapel last night. “Hey, did I say that loud enough?” he asked, looking around at the various evolutionary biology and history and philosophy of science worthies — Lewontin, Kitcher, Sober, Ruse, Dennett, Richards, and so on — milling about. Ron’s smiling insult was a mocking attempt to redress the widespread criticism that he had let me off easy in our notorious Bloggingheads conversation. A spirit of raillery was in the air, given a vigorous kick at the beginning of the evening by Harvard geneticist Richard Lewontin. Little of the secular sanctimony of the 1959 Darwin centennial (see below) was in evidence. Read More ›

Two recent papers, one in the Journal of Morphology and another in Ornithological Monographs, as well as a ScienceDaily news release titled “Discovery Raises New Doubts About Dinosaur-bird Links,” contain criticisms by evolutionists of the dino-to-bird hypothesis that you would normally expect to hear only from skeptics of neo-Darwinism. Their remarks not only cover problems facing the dino-to-birds hypothesis, but also lament the politically motivated drive to push that hypothesis and ignore scientific dissent. The ScienceDaily article observes that some aspects of bird morphology are simply incompatible with the standard hypothesis that birds evolved from maniraptoran theropod dinosaurs: It’s been known for decades that the femur, or thigh bone in birds is largely fixed and makes birds into “knee runners,” Read More ›
