Here’s another study that homophobic bigots can casually ignore; Two evolutionary psychologists (yes, these guys are making the news a lot recently) have offered a unique explanation as to the evolutionary value of homosexuality. You see, since gays tend to not breed, the basic question of “why would homosexuality persist if the genes for it would be selected out” hasn’t yet been answered definitively.

I’m not sure if homosexuality is actually a genetic trait. I tend to agree it might actually be caused instead by embryological  development (the best explanation I’ve heard has to do with birth order and how the brain may be masculinized or feminized depending on the level of testosterone exposure in the womb, but I’m no scientist). Either way, I think it’s a pretty interesting study, especially in light of how they conducted it. They studied a relatively small tribe in the Pacific called the Samoa, who don’t seem to share our intense bigotry, openly accepting and identifying their gays. Because of their close kinship, they hoped to examine how our more primitive ancestors lived (we tend to be way too independent in North America). Homosexual men were more likely to help take care of their nieces and nephews, and the consensus is that these “super uncles” helped the fitness of their kin, and therefore could help pass on their genes (albeit a smaller portion of them) by being good helpers.
