| Another commenter has already dealt with marriage - it's much more complex that you think - just to add you appear to forget the womans point of view ( and genes ) entirely in you're assessment of the best strategy - where 'sow wild oats' obviously doesn't apply. Also I'd have to say that one of the great successes of humans as a species is they are much more adaptable without genetic change than most - ie escaping our genetics is something to be acknowledged and celebrated not berated. > Homosexuality, indeed, is a discouragement to species survival (if I understand your meaning correctly). Yet you're claiming it is unlikely that it doesn't originate in genetics? I said the sex drive is likely largely genetic - note that there are two sexes! - women who are attracted generally to men and vice a versa - so both attractions would be encoded in the same genome - each by many factors. The question them becomes in any individual, which ones are switched on to what extent. Genetic variation is a cornerstone of evolution, without it you can't genetically adapt or change. Clearly sexual attraction involves the brain, which is one of the most adaptable organs in the body - so environment is very likely going to play a role - these things are not absolute. Finally you seem to be under some illusion that the current state of humans is perfect adaption, rather than continuous work in progress against a constantly moving target. |
