Elaine Morgan embraced the aquatic ape theory publishing many articles showing her beliefs and theories about the aquatic ape. The theory had been rejected for many years until Morgan stood up and questioned our origins. The argument supporting the aquatic ape hypothesis grows in strength as new evidence and theories are being discovered.
             There are many features that set Homo sapiens apart from the apes and those features appear to relate them to aquatic animals. The absence of fur on mammals only occurs in two types of habitat, a subterranean one and an aquatic one. There are certain types of moles called 'Somalian mole rats' that never venture above ground, the only other hairless mammals are those that live in the water, such as the whales, dolphins and walruses. There are also the waders or wallowers that spend a lot of their time wading in the water, such as the elephants and rhinoceros. The loss of hair in the water makes the body more streamlined and fur was not needed to protect from the sunrays.
             The savannah theory says that humans lost their hair in order to "prevent over heating in the savannah" (AAT leaflet), but no other mammal's evolution has ever naturally selected this strategy. The mammals that live on the savannah have a covering of fur to protect them from the harsh sun, a coat of fur reflects a certain amount of sunlight. Another theory for hair loss is that it facilitates sweating, but again most of the mammals on the savannah can sweat quite effectively without having to lose their fur. One theory by a man called Phil Nicholls states "advantageous in mammals because it reduces drag and thereby lowers the energetic cost of locomotion". Nicholls also argues that only extremely large sea creatures lose their fur.
             Humans have different sweat glands to most mammals, these glands lose large amounts of water and salt. If humans were evolved on the savannah with these sweat glands ...
