Current Textbooks Misuse Embryology to Argue for Evolution

Sylvia Mader’s 2010 textbook, Biology, uses colorized versions of Haeckel’s embryo drawings with only a few small modifications. As seen in the side-by-side comparison above, the black and white drawings are Haeckel’s original drawings and the colored drawings are from Mader’s 2010 textbook. Just like Haeckel’s original drawings, Mader’s colorized drawings obscure the differences between the early stages of vertebrate development in order to give students the following misleading caption: “At these comparable developmental stages, vertebrate embryos have many features in common, which suggests they evolved from a common ancestor. (These embryos are not drawn to scale.)” (Sylvia S. Mader, Biology, p. 278 (McGraw Hill, 2010).) Click the graphic for the full picture. Haeckel’s long-discredited recapitulation theory is not necessarily Read More ›

Revisiting Those Pesky Embryo Drawings

A few years ago, former NCSE-spokesman Nick Matzke called complaints over the use of Haeckel’s embryo drawings in textbooks a “manufactured scandal.” However, a variety of leading scientific authorities — proponents of neo-Darwinian evolution — have also complained about the use of these drawings and the way that embryology is used to support evolution in biology textbooks. Are these authorities in on the big conspiracy to “manufacture” this “scandal” too? Here’s where things stand today: Despite the fact that (in 2010 at least) out-dated concepts like “ontogeny recapitulates phylogeny” have been almost completely removed from new textbooks and that many (though not all) new textbooks use embryo photographs instead of fudged drawings, an examination of both recent textbooks and complaints Read More ›

Doug Axe Knows His Work Better Than Steve Matheson

When Stephen Meyer faced Steve Matheson and Art Hunt at Biola University last month, one scientist’s research was key in their debate: Doug Axe, Director of Biologic Institute. While there’s a good deal of back and forth on the subject, for the first time Dr. Axe has something of his own to say on the subject of his work. From Biologic Perspectives: The specific work to which Meyer, Matheson and Hunt referred [4] has added to the scientific case for functional protein sequences being extraordinarily rare within the whole space of possibilities. Matheson started off by arguing not that this deduction of extraordinary rarity is incorrect, but rather that it is irrelevant to the debate between Darwinism and Design. Axe Read More ›

The Fact-Free “Science” of Matheson, Hunt and Moran: Ridicule Instead of Reason, Authority Instead of Evidence

I was not in Los Angeles on May 14, when Stephen Meyer debated Stephen Matheson and Arthur Hunt at Biola University. But I have followed some of the blog war that preceded and followed the debate–a blog war that now includes Richard Sternberg and Laurence Moran. Since Matheson, Hunt and Moran are all tenured professors at institutions of higher learning, one might have expected a discussion based on reason and conducted in a collegial spirit. And since the discussion is about science, one might have expected lots of references to evidence published in the scientific literature. But Matheson, Hunt and Moran have abandoned reason and resorted to ridicule; and instead of citing evidence they expect us to bow to their Read More ›
