A Reply to Carl Zimmer on Embryology and Developmental Biology

I recently read Carl Zimmer’s response to my critique of his November, 2006 article in National Geographic. In this post I will discuss Zimmer’s response to me regarding embryology and developmental biology. The embryonic hourglass is the idea that vertebrate embryos (like those of fish, amphibians, reptiles, birds, and mammals) start off developing very differently, converge with some similarities at the pharyngular stage, and then again diverge. I stated in my original article that “vertebrate embryos start off quite differently,” but that “Zimmer’s diagram selectively displays embryos from the encircled stage where they are most similar.” The implication is that this falsifies the idea that evolution proceeds by tacking on new stages of development because these vertebrate groups start off Read More ›

A Tall Tale of Evolution: The Neck of the Giraffe

German geneticist Wolf-Ekkehard Lönnig Tackles Giraffe Evolution Last year, German geneticist Wolf-Ekkehard Lönnig critiqued evolutionary accounts of the infamously complex long neck of the giraffe. He recounts how various Darwinists had claimed things like “the evolution of the long-necked giraffe can be reconstructed through fossils,” but Lönnig concluded that “the fossil evidence for the gradual evolution of the long-necked giraffe is — as expected — completely lacking.” Lönnig has now written part 2 of his refutation of this evolutionary tall tale, where he now shifts the focus away from paleontology and on to giraffe anatomy, diet, behavior, and zoology, tackling evolutionary hypotheses about giraffe origins. Part 2 can be read at “The Evolution of the Long-Necked Giraffe: What Do We Read More ›

The Positive Case for Intelligent Design Presented at Boise State University–Darwinists choose to “abstain.”

On March 19 I lectured at Boise State University (BSU) to about 50 mostly-friendly students and community members on “The Positive Case for Intelligent Design.” (The lecture was largely based upon a document I produced by the same title, available here.) BSU is the notorious home of their beloved undefeated-but-yet-#5-ranked Bronco football team, but my lecture was only sponsored by the IDEA Club at Boise State. The club’s leader reports that he’s recently received unfriendly e-mails from a hostile Darwinist. The club’s leader responded nicely, saying, “I hope that you would be willing to come [to Casey Luskin’s lecture],” and also defended himself saying “I am quite content for someone to disagree with my view, but I do not respect Read More ›

Ken Miller Rewrites his Textbooks, then Rewrites History: Miller’s Evolving Position on Haeckel and Evolution

Last year I wrote about some memory lapses that Brown University biologist and textbook author Ken Miller apparently had while testifying during the Kitzmiller trial regarding his own textbooks. Ken Miller has authored many biology textbooks, and his first textbooks (from the early 1990’s) used Haeckel’s fraudulent embryo drawings and blatantly promoted the idea that ontogeny recapitulates phylogeny. To his credit, Miller fixed later editions of his textbooks–he took out Haeckel’s drawings and replaced them with real embryo photographs, and he also stopped promoting recapitulation theory. Like many Darwinists, however, Miller then tried to rewrite history and pretend that these mistakes had not been promoted by biologists for many decades. First, read what Miller & Levine’s 1994 version of Biology: Read More ›

The Evolutionary Gospel According to Sean B. Carroll: Review of The Making of the Fittest

Over at the International Society for Complexity, Information, and Design (ISCID) archives, I’ve posted a review of Sean B. Carroll’s book entitled, “The Evolutionary Gospel According to Sean B. Carroll: A Review of Sean B. Carroll’s The Making of the Fittest: DNA and the Ultimate Forensic Record of Evolution” (W.W. Norton, 2006). Below are a few excerpts of the review: To ensure the reader adopts his own view of evolution, Carroll resorts to scare tactics. After a bleak discussion of the potentially disastrous consequences of global warming, Carroll explains that “acceptance of [evolutionary biology’s] facts” is not “a matter that should be open to political or philosophical debate.” Carroll, who interestingly always capitalizes the term “Nature,” quotes Peter Medawar, saying Read More ›
