More on genetics and homosexuality
A nice piece by Steven Pinker taking off on the pheromone study that I discussed a couple posts ago. He also makes the point that I was trying to make here: "The difference in the brain responses of gay and straight men does not, by itself, prove that homosexuality is innate; after all, learned inclinations, like innate ones, must reside somewhere in the brain."
I'm less sure about his take on the origins of homophobia, but this line is funny enough to quote:
Why didn't evolution shape straight men to react to their gay fellows by thinking: "Great! More women for me!"
