We have just as much hair all over our bodies as chimpanzees or monkeys or any other furry primate. Most of it is just very short and light. Its called vellus hair or peach fuzz. I think its bizarre that most of our thick hair is on the tops of our heads. Imagine if dogs looked like that! On second thought, maybe its better if you dont imagine that. Research shows that we humans lost all our body hair through evolution about a million years before somebody finally figured out how to purchase clothes at one of the first primitive Walmarts. One theory says that we lost our all body hair in an attempt to avoid parasites like ticks, fleas, and lice, and that weve only kept the hair on our heads because other people think its pretty. As proof, consider that you havent seen many bald pregnant women. There is a very special kind of louse that only lives in human clothing. DNA tests indicate that it evolved from a louse that only lives in human hair, and that this happened about 42,000 to 72,000 years ago. So, thats probably roughly when clothes first went on sale. There are no special lice that live in any form of footwear, so DNA testing cannot solve the troubling mystery of exactly at what point in the past Hello Kitty themed socks were invented.
