Evolution and homosexuality (5)

(Continued)

There is a slow gradual transition from agricultural, pastoral societies to 'civilised' (i.e. more complex and organised) societies. Organisation requires 'leaders'. Natural leadership skills aka charisma works fine in small groups, but without mass media, there has to be a hierarchy of administrators or politicians or priests (all the same thing, really, and all in it for The Greater Good as well as naked self-interest). Advance requires technology and science; an organised society needs artists and craftsmen to celebrate the achievements of The Great And Good*. A society that advances needs an army to protect itself from less successful ones.

Now, if you're an Average Joe with your own family to look after, you'll have little time or enthusiasm for all this (even though in the grander scheme of things, they benefit you). So Nature needs to have some people who don't have to worry about kids. On the one hand, Nature could have just arranged it so that more people were infertile, but this would defeat the object, and humans would die out - far better to have slightly too many children and for some of these to be gay (as covered in Part 4).

Furthermore, Nature is a kindly old soul - it would be downright cruel to have straight but infertile people. So those rôles - as warriors, administrators, artists, scientists etc - are ideally suited for gay people. They can still form happy relationships but their lives aren't bogged down with the minutiae of daily life.

Which sort of brings up to date ... but the story continues ...
