evolution, modularity and homosexuality

[luckyme]

There is some support for homosexuality to be carried along on a species fitness level. I haven't bought into that yet, but haven't ruled it out as playing a part. Main reluctance comes from a parsimonious take on modularity.

Until I'm convinced that it isn't a normal spin-off from our modular nature regarding sexual behavior in general, it's hard to support a group level explanation.
To oversimplify it - our mind/brain has lots of modular aspects and given the mixes that occur and the ubiquitousness of the sexual/power/bonding ones we can't help but have some form into various homosexual holistic behavior in some individuals.

From an similar angle - as long as sex is a major focus of a successful social modular-minded species, homosexuality is going to appear. The arousal triggers are not directly hooked to reproductive copulation.

Focused fitness seems a distant second at best ???
