Why does testosterone lead to men having hairy faces, but not women. That doesn't seem to be for any specific reason does it.

Back to armpits though. I guess that when we used to need hair for warmth, it grew thicker around the main joints (because it had to resist the friction and not fall out) and so now that we're wearing clothes it's the last to go. It was the toughest we had growing on us in the first place so it's stayed with us the longest.

I think that's probably the answer, but it's still a bit weird about the beards though. Maybe because guys are and always have been so visual, and so needed to see their mate's facial features back when we were evolving?
