Humans Have The Same Amount Of Hair As a Chimp….Really

It might seem hard to believe, but we have about the same number of hairs on our bodies as a chimpanzee, it’s just that our hairs are useless, so fine they are almost invisible. We aren’t sure quite why we lost our protective fur. It has been suggested that it may have been to help early humans sweat more easily, or to make life harder for parasites such as lice and ticks, or even because our ancestors were partly aquatic.

But perhaps the most attractive idea is that early humans needed to co-operate more when they moved out of the trees into the savanna.
