Fun fact 2/18/2017

The aquatic ape theory, popularized in the 1970s and 1980s, suggests that early hominids lived in water at least part of the time. This aquatic lifestyle supposedly accounts for our hairless bodies, which made us more streamlined for swimming and diving; our upright, two-legged walking, which made wading easier; our layers of subcutaneous fat, which made us better insulated in water (think whale blubber); and pruney fingers after being soaked in water which made gripping easier underwater.
