I have a completely unscientific theory that homosexuality is an evolutionary advantage to humans (and maybe some other animals) because homosexual aunts and uncles contribute their resources (time, money, wisdom, etc) to the raising of their sibilings' children since they don't usually have children of their own to raise. So in a family with 2 straight and 1 gay kids, the next generation has the resources of 5 adults to help raise them instead of 4.
