Barack Obama: As I said, my views have been evolving... Caveman: Wrong word.
Harley, evolution is a complex thing, and evolutionary selection doesn’t necessarily follow a simple story. For example, there is evidence that female relatives of male homosexuals have higher than normal fertility, in many cases. This supports a hypothesis that some genes which may be associated with homosexuality in males which carry them could support fertility in females which carry them. This, in turn, means that the genes will still be maintained in a relatively high frequency in the population, even if the men that carry the genes have fewer children than normal. Differential benefits to different genders is actually quite a common phenomenon in genetics.
I know that you really weren’t interested in that, and probably won’t even read it, and it is kind of a side note to this political cartoon, but I keep seeing questions like this all the time and I think people ought to know that there IS an answer.
