Gay genes and gay rights: On the science and politics of sexuality
If homosexuality has a genetic basis, and if gay sex produces no offspring, why hasn’t the culling force of natural selection bred it right out of the species? Neuroscientist Simon LeVay has recently taken to the electronic pages of the Huffington Post to tout his latest book and offer a few hypotheses.
In light of the article’s popularity, Professor LeVay was asked to join a panel of speakers to discuss not only the genetics of sexual preference, but also the social and political implications of such research. Since I had written on this topic on the Practical Ethics blog, I was invited to take part as well.
