Homosexuality has been around as long as diabetes. I think it is a genetic abnormality and its allele has been protected by nature from being ex sponged from the species by hybrid protection. The recessive allele has always been protected in the heterozygous condition from being deleted from the genome. So two normal individuals can have homosexual offsprings. It seems a bit far fetched right now to think of homosexuality as an organic disease. There is more and more research, not only in humans but other animals that is leading in that direction. So when it happens don't be surprised.

Well considering it would evolve a species into extinction, I'm thinking no. Even if you believe evolution tries variations to see what works it's an adaptation that would be doomed to fail.
I'm not bashing the choices of others, but purely on the basis of evolution it does not make sense. There are species that are hermaphrodites, but that evolution would be several million years down the road for humans as a species.

There are many conditions which are not conducive to reproduction of offspring, such as Sickle cell disease and Cystic Fibrosis. But in their carrier states confer a selective advantage to the group/ village/ family as a whole. Perhaps homosexuality, although obviously not a disease, in some way contributes to society in this way. It certainly has been maintained in the gene pool, as you rightly point out. As to whether it is a genetic trait or not is still being debated, but it certainly acts like one. Perhaps, like Sickle Cell anaemia and Cystic Fibrosis, it is the homozygous form of a beneficial condition.
Just my thoughts.

Variation is absolutely critical to evolution by natural selection. So variation in sexual orientation would absolutely be consistent with the same type of variation in many other aspects of human behavior (agression, nurturing, intelligence, physical strength, endurance, right-vs-left-handedness, etc. etc.)
E.g. just as the majority of people are right-handed, which is evidence that it was once associated with some gene that had survival benefits, there are still a minority of left-handed people, and a large range from strongly right-handed to strongly left-handed to all ranges of ambidexterity in between (like my brother who throws a ball with his left hand, but writes and draws with his right hand).
So, yes, homosexuality does seem to be a natural consequence of the same variation that causes evolution. But that does not mean we are evolving towards a more gender-neutral species (if that's what you mean).
Homosexuality is as natural as left-handedness. (And I say this as a right-handed heterosexual.)

How can it be, such a trait would be heavily selected against by natural selection since it is a dead end for reproduction.
