Why do we have hair in certain places of our body? I understand that the hair on our head keeps heat from escaping because the majority of the heat that we lose is through our head. I understand that eyebrows and eyelashes keep sweat and other particles out of our eyes. I know that nose and ear hair act as filters. But why do we have hair under our arms or on our legs?
I've also been reading about evolution in my science class and I have a theory. We have evolved into a species that no longer needs hair to keep warm - we've invented other ways to tackle this problem. So, that being said, perhaps baldness is evolution in progress! Maybe in 1,000 years, everyone will be bald. Just my odd thought for the day.
