discovery institute hahahhahahahahahahahahahahah!Here come the liars and misreprenters at Panda's Thumb. And once again it is laid bare that the militant atheists at Panda's Thumb have nothing in common with real scientists...
On June 19, the day after Darwin's Doubt was first available for purchase, Nick Matzke published a 9400-word "review" of the book in which it appears that he tried to anticipate many of Stephen Meyer's arguments. Unfortunately, he often either guessed wrong as to what Meyer would say or -- assuming he actually read the book as he claims -- misread many of Meyer's specific claims. As I showed in a previous response to Matzke, Matzke repeatedly misquoted Meyer, at one point claiming he referred to the Cambrian explosion as "instantaneous," when Meyer nowhere makes that claim. Indeed, Matzke faulted Meyer for not recognizing that the Cambrian explosion "was not really 'instantaneous' nor particularly 'sudden.'" Oddly, he also criticized Meyer for not recognizing that the Cambrian explosion "took at least 30 million years" -- despite expert opinion showing it was far shorter.
Since Matzke published his review, The New Yorker reviewed Meyer's book. Gareth Cook, the science writer who wrote the piece, relied heavily on Matzke's critical evaluation, even though Matzke is a graduate student and not an established Cambrian expert. Cook uncritically recycled Matzke's claim that the Cambrian explosion took "many tens of millions of years," even saying that the main problem with Darwin's Doubt is that Meyer failed to recognize this alleged fact.

In fact, Matzke's preemptive -- or hastily written -- review not only misrepresented Meyer's view, it also misrepresented the length and character of the Cambrian explosion as numerous authoritative peer-reviewed scientific sources on the subject clearly show.
Before going on, let's briefly look first at what Meyer actually says. First, Meyer does not equate the Cambrian explosion with the entire radiation -- as most Cambrian experts also do not. By "radiation" here I mean the period of time in which all the new phyla, classes, orders that first arose during the Cambrian apparently did so. Instead, he equates the Cambrian explosion with the most explosive period of the Cambrian radiation (as most Cambrian experts do) in which the vast majority of the higher taxa arose. He asserts specifically that the re-dating of critical Cambrian strata in 1993 established that the strata documenting the first appearance of the majority of the Cambrian phyla and classes took place within a 10 million year period -- a period Meyer does equate with "the explosion of novel Cambrian animal forms." (pp. 71-72) As he describes it, "these studies [i.e., radiometric analyses of zircon crystals in Siberian rocks] also suggested that the explosion of novel Cambrian animal forms" took about 10 million years. (p. 71)
