The aquatic ape hypothesis

Why do humans differ from other primates? What do those differences tell us about human evolution? Elaine Morgan gives one hypothesis that explains our anatomic anomalies--why we walk on two legs, why we are covered in fat, why we can control our rate of breathing, and more. The answers point to one conclusion: millions of years ago our ancestors were trapped in a semi-aquatic environment.
