I am a public speaker by trade; I speak on the evolution and future of sex, romance, marriage, adultery and divorce. And one of the first questions I am always asked is: "Why homosexuality?"
For years I have given the standard anthropological answer: kin selection. In short, we share our genes with relatives. So those who help their relatives are actually nurturing some of their own DNA. Hence gays and lesbians pass on their genetic proclivity for homosexuality by helping nieces, nephews and other kin.
