Thread:Comments:Gay couple elected prom king and queen in Maine's Sanford High School/Silly/reply (68)

However we are not in a life or death situation anymore so (at least many of us) can override any instinctive suspision of all things foreign i.e. a gay couple at high school aren't going to wipe out the straight kids thus they've been accepted.

It seems simplistic to me to suggest however that evolution acts to concentrate selfish genes - depending on the definition of selfish. Evolution can develop traits that are markedly unselfish, such as the poison in certain frogs - which might not aid an individual frog from being eaten but will protect the species as a whole.

I wonder also whether traits may develop which offer no advantage to the species but that also offer no distinct DISadvantage and thus may be allowed to progress. This could be a route through which any genetic susceptibility to homosexuality could travel (again I'm ignorant of where the scientific world stands on nature vs nurture as far as homosexuality goes)
