Carl Zimmer,who is of course, THE MAN! of parasite parables and paraphenalia, has posted a more in-depth analysis of this story at his weblog, The Loom , going into the genetic/molecular mechanism. Additionally, Zimmer responds to the creationist take on the story (the usual move-the-goalpost panic of those advocating irreduceable complexity). Of larger concern, why does this incredibly fascinating discussion about scientific sleuthing and the potential and beauty of proteomics, get automatically sidelined into a discussion on "what does creationism say about this?" I don't blame Zimmer for responding; indeed, that's the duty of science writers as gifted as he. But it diminishes the power of the story itself to have to ask, imnsho.
