It also serves neat secondary social functions! Among penguins, homosexual couples sometimes adopt orphaned chicks that heterosexual parents would ignore to favor their own offspring.
EXACTLY And this is seen in many other living species as well. Not only does it keep the population at a sustainable number but it also keeps most of the species alive
No. It is not because species that are dying and have 2 members left can be homosexual. Although you could say that due to overpopulation (and people being close) could cause one to realize their homosexuality or however homosexuals find out... I'm not really sure XD
Do you have proof of the last of a species being homosexual, if so please give some examples with sources. Not that I think you are making shit up, but I think you are making shit up
But how is that possible when the genes can't be passed down? It seems more like a bad thing since the propagation of the "gay genes" would actually lead to a downfall of the species. So evolution would actually want to get rid of it. That's how evolution works right?

I read somewhere (don't remember where, so it could be hogwash) that the gene which causes homosexuality in one sex causes enhanced fertility in the opposite sex, so that compensates for the lack of offspring from gay people. Otherwise the gene would have probably died out long ago
Well, thousands of animals go extinct everyday, without Human Intervention. Nature is always killing off species, and Humans are inevitably nearing our expirery date. There's a 90% chance humans will go extinct in 10,000 years, either from pollution an overpopulation, the arrival of the next ice age, or an asteroid similair to that which killed the dinosaurs. Perhaps Homosexuality is humanities greatest defense to combating the most solvable problem, overpopulation?

But how does the gene pass on if gay people can't reproduce? And with the acceptance of gay marriages, gay people aren't pressured to reproduce with the opposite sex. Unless you're telling me that adoption among gay people are actually rare and they get a third party involved. I still don't understand how the gay gene is being naturally selected over the non-gay gene.

Okay so say a mother has a gene which will make her son gay, this gene will make her daughters more fertile. It doesn't matter if gay people don't reproduce because their siblings (which almost everyone would have before modern society) would reproduce more due to the increase in fertility

And it's not selected over another gene, it just managed to not die out up until this point
Again, I don't remember where or when I read this, so this may just be nonsense. However, it kind of makes sense to me
because it is a recessive gene, like for example blue eyes, you might have them but your parents don't but they gave you blue eyes none the less because it was in their genes
OK that makes sense. But wouldn't that mean that she has to be super fertile for it to happen. So in the instance above, the girl has to produce more than twice the average amount for the gene to spread.

Yes, that's what I meant with the enhanced fertility thing
Well, overpopulation in an environment can increase estrogen and other female hormones in a woman's body, as a means of controlling/decreasing her fertility. Increased female hormones during a pregnancy can trigger, or increase the probability of triggering, developmental factors that are known to correlate with homosexuality. There's probably both a developmental and a genetic side to it, and neither is particularly well understood yet.
