Denyse O’Leary is a very silly person, but you all knew that. One of her latest entries on her silly Design of Life blog, which purports to be promoting Dembski’s silly book of the same name, is treading old ground. She’s claiming that convergence is common, and that marsupial lions and wolves and squirrels are evidence of some kind of natural destiny. She’s getting all of this from Michael Denton, but the similarities are in ecological niches (sometimes, not even that) and in the names, and contrary to Denton, the similarities are only superficial.
Laelaps has the details on those convergent marsupials. The differences are very easy to spot, especially when you’ve got an expert guide with a battery of photos.
