I don't have hair all over my face because I shave every day. However, this is not true of all men.Can you tell me why humans do not have hair all over their bodies and face like gorillas and bonobos do? Without guessing? Missing chromosomes? Where are the intermediaries? Hair? No hair? They disappeared perhaps?
More seriously, our ancestors may have evolved to lose their body hair so as to be able to lose heat by sweating when pursuing prey animals over long distances.
