The effeminate sheep & other problems with Darwinian sexual selection

The title of this post is actually the subtitle of a fascinating article by Jonah Lehrer, in Seed magazine. It was published about a year ago, so you might have heard something about it.

The article summarizes the theories of Joan Roughgarden, a biology professor at Stanford who wrote a book about homosexuality in the animal kingdom. Her theories are thought out well enough to have merited publication in peer-reviewed journals, although, unsurprisingly, they're controversial, even among other biologists. But she does present a case that seems to answer the question: If Darwin had it right, and you believe being gay is genetic (both views I buy), why didn't this trait get wiped out by thousands of generations of natural selection?

It's an interesting read.

And you know this guy has already read it. Many, many times.
