PZ screwed up badly in the Q&A.
PZ has now put up
his own account onto pharyngula
quote:
Apparently, in the Q&A for my talk (which you can now listen to; MacLatchie is first up), he asked me, I think, question #3 from his list, but I couldn't really tell. As is typical, he turned it into a long-winded turgid mess, and I'll be honest, I really couldn't grasp what he was trying to ask, and I think he was actually getting at two different things. One is that there are differences in the embryological origins of some organs; this bothers him, apparently, because he's sitting there expecting that there shouldn't be any differences in how, for instance, the neural tube forms, because it's a primitive structure, and therefore, because development is supposed to recapitulate evolution, they should be identical. I missed that; I was trying to see a more intelligent question in his verbiage. Now that I've read the papers he was waving around, I can answer a little differently: yes. There are differences in how different organs form in different species.
So?
