Homosexuality either occur because of random genetical mutations, or because of a special sort of enviroment that they grow up in. I go for the first.

So my point is that homosexuality doesn`t reallly benefit a specie, the more of a specie, the better. Especially for specie like homo sapiens, who get few children. Otherwise, there should have been an increase in percentage of the amount of homosexuals thru time, but I haven`t seen anything pointing out that.
True... but if it was genetics we would also see a decline of homosexuals in the modern world (since they don't breed). We do not.
In fact there should by all standards be far more homosexuals just prior to the sexual liberation period (you can call it differently but you know what I mean). Nothing seems to indicate as much.

Neither does it explain how identical twins can have different sexuality...
