9) The Aquatic Ape Theory
Why aren’t humans just covered in body hair? We are the most hairless ape on the planet, and one theory attempting to explain why ws called the ‘Aquatic Ape’ theory. This theory goes that our long-ago ancestors started swimming to forage for food, promoting hair loss and bipedalism in the process. Evidence includes the fact that babies, when born, will hold their breath and make swimming motions until their heads come up above water.
