What makes humans stand out among primates?
We’re naked and unusually sweaty.
Yes, we’re also distinguished by upright walking, big brains and advanced culture. But here I want to focus on our sweaty bare bods.
Millions of years back our ancestors were likely as hairy as chimpanzees and gorillas. Over the course of human evolution, our lineage traded its fur coat for a covering of minuscule body hairs and a few ample patches over the head, armpits and nether region.
