Science has a New Explanation for Homosexuality
When James O’Keefe’s 18-year-old son Jimmy came out as gay, James felt like he had failed him and regretted that Jimmy wouldn’t have kids of his own. Though he now realizes that Jimmy might one day have kids, as a medical doctor O’Keefe still wondered about the genetic and evolutionary factors that made his son gay.
“Viewed in the light of evolution,” O’Keefe said in a recent TED Talk (video below), “homosexuality seems to be a real self-defeating non-productive strategy. Gays have 80 percent fewer kids than heterosexuals. This is a trait that ought to go extinct in a few generations, yet down through recorded history in every culture and many animal species as well, homosexuality has been a small but distinct subgroup. If this were a genetic error, natural selection should have long ago culled this from the gene pool.”
