The problem is, how do you get the point through to PZ and other biologists who come at the question from an evo-devo PoV?

Why bother? PZ's rather misguided rant isn't doing very much damage. Just ignore him, I figure.

Maybe it is a slow news day. PZ's rant got Slashdotted:

PZ has stooped pretty low with the publicity recently:

Maybe he was trolling with his Kurzweil rant. He does have a history with this subject matter, though:
