> Homosexuality is interesting from this perspective too - common enough that evolution has to be selecting for it,
Are we sure this is the case? I think it's more like homosexuality isn't extremely selected against on a population level. Evolution doesn't really select for, more like evolution is a process in which least-viable-specimens are killed off for their environments. It could very well be that a small number of homosexual specimens are simply irrelevant to evolutionary fitness.
