Strange bedfellows out of sworn enemies: “Evolutionary scientists and Christian-right literalists both agree, for different reasons, that homosexuality is unnatural.

Now, while the rest of the country is grappling with the issue of gay marriage, Stanford evolutionary ecologist Joan Roughgarden is trying to untangle Darwin’s mess by publishing Evolution’s Rainbow: Diversity, Gender and Sexuality in Nature and People. Roughgarden’s thesis begins with the idea that since homosexuality is not a reproductive strategy, according to Darwin it’s an aberration that should die off. But instead of deciding that homosexuality is wrong from an evolutionary standpoint, Roughgarden arrived at another conclusion: Darwin’s theory of sexual selection must be wrong.” (AlterNet)
