paradox42 said:My own idea on this topic is that the studies that hint at homosexuality (in males at least) being related to an overabundance of testosterone in the womb, or even the homo's own body, are leading us towards the survivability enhancer. To wit, the prime characteristics of testosterone psychologically are that it increases sexual desire and aggressiveness. Add to this, the demonstrable fact that humans fight far more fiercely when defending things they love, and especially people they love.
Now, most studies I've read of mankind's primitive beginnings suggest that our ancestors were loosely organized in tribal bands, with males typically providing hunting and front-line fighting, and females providing gathered food and defense. There's no particular reason to suspect that either males or females were more inclined toward crafting of tools or leadership, aside from the tendency of most male primates to try to force themselves into leadership positions and bully everybody else into going along with them. Child-rearing would be done mostly by the females and any adolescent or elderly males too young or too old and infirm to hunt reasonably well.
If we accept that scenario of the dawn of human society, what use then would a homosexual male be? If he occurs as a result of more testosterone than his hetero clanmates, it would mean he's more aggressive than they are. This, in turn, would mean that when moved to fight, he would fight more fiercely. More interestingly, since a man would not typically hunt by himself, but rather with companions from the tribe, this primitive homosexual would spend much of his time near the healthiest, most virile and strong members of his clan- and would be placing himself in danger with them regularly. It is quite likely that he'd fall in love with one or more of them, at least on some level. This, in turn, means that he would fight more fiercely to defend them without even having other members of the tribe around. He would, in fact, fight more fiercely than a hetero man placed in the same situation. And in a life-or-death struggle, fierce fighting can often make the difference between life and death, as our friendly neighborhood D&D Barbarian teaches us. Finally, since combat is by nature dangerous and sometimes leads to deaths of clan members, we must look at the fact that if a straight man with one or more children was out hunting and got killed, this meant that the children would be down one parent and thus harmed by it. But if they lost their homosexual uncle, who had no children of his own, it would surely have a less traumatic effect in a social perspective.
So to state my idea, finally and clearly, I believe that homosexual males were "designed by evolution" (if you will pardon the obviously-unscientific phrase) to be a clan's supply of expendable, front-line combat troops. We were Nature's own military for the human species. If this explanation is correct, it makes the anti-gay stance of several modern military organizations around the world more than a little ironic! If nothing else, this idea has some potential for coming up with fantasy civilizations and scenarios.
Very interesting theory. However, how would you explain the role of berdache in most tribal societies? For those that don't know, berdaches are typically males of a tribal society who specialized in the work of women and formed emotional and sexual relationships with other men. They really didn't go out hunting with the other men. There are also female berdaches who took on men's work [such as hunting] and married other women--as seen among some Plains Indians tribes.
In many instances, these individuals would also fill a special spiritual role and, therefore, were often times valuable to the tribe. For example, among some California tribes, male berdaches were called upon to bury and mourn the dead, because such close contact with the spirit world was considered too dangerous for others.
I know this is taking the subject out of the genetic realm and placing it more in the sociological, but I'm curious how the role of berdaches would be explained from an evolutionary standpoint [if it can be explained at all]. Also, I'm interested because my background is in Cultural Anthropology.

And to tie the subject back into the Forgotten Realms, there are many tribal societies across the face of Faerun. We have the Uthgardt in the northwestern Silver Marches, the Nar in northeastern Faerun, the Shaaran of the southeastern grasslands, and the southwestern Chultan or "Tabaxi" which is a reference to the "one great tribe" that they feel they belong to. I know this is analogous to tribal societies of own world, but I feel that among the tribal societies of Faerun, homosexuality would probably be present and accepted.
