You'll have to read Evolutionary psychology: the adaptive significance of semen flavor to find out what Coyne thinks of evolutionary psychology. I think he's captured the essence of the movement.
P.S. I was looking for an appropriate illustration of the behavior that Coyne describes. Turns out that if you enter the appropriate term in your Google search box, you'll find quite a few photographs out there on the internet. I decided not to use any of them but the search was interesting.
