Jacob, I'm new to this to a certain extent, but consider that the mating ball of snakes is most likely not actually 10k, simply because it could possibly be picked up by 10k snakes. In addition, this mating ritual continues with all female snakes of the breed. So it isn't a a matter of best snake gets the girl.....natural selection wins! It's a slow moving process over many many breeding cycles.
Regarding fur/hair, I'm actually most interested why we retain any. In particular as I approach my late 30's, why does it want to disappear from my head, and make its way to my earlobe?
