Prostitution At Monkeyland!
But, who would have thought that paying for sex extends to the animal kingdom?
According to the Discovery Channel, evidence has been found that male monkeys "pay" for sex by untangling and cleaning dirt and parasites from the fur of the females. The higher the ratio of male to female monkeys, the more grooming the male monkeys need to do to get their sex-life going. This process can last from a few seconds up to half-an-hour and turns the monkeys on. Scientists are guessing that this is how foreplay in humans developed. Also, it seems that materialism is part of primate social life as well: the higher status monkeys don't have to work as hard as lower status monkeys have to for sex.
