The top-down pattern of appearance of animal phyla during the Cambrian explosion represents major conflicting evidence for Darwinian evolution.
A bumper sticker I’ve seen around in Seattle protests the War on Terror, warning that “We’re making enemies faster than we can kill them…”
In Chapter 11 of Darwin’s Doubt, Stephen Meyer responds extensively to critics who have claimed that the evolution of new genes is well understood.
Ironically, the rarity of genes and proteins in sequence space means that even thirty million years is not nearly enough time for the neo-Darwinian mechanism to generate a new gene or protein, much less a new animal form.
There’s an old joke about a book critic. Asked if he has read the new book by a certain author, he replies, “No, I only had time to review it.”
