Self Aware Monkeys Learn About Anatomy Using Mirrors

Great apes, alongside humans, have long been known to be self aware. Chimpanzees, for instance, are famous for their individuality and remarkably human-like behavior, even playing dress-up in front of mirrors and referring to themselves in sign language. However, a new study shows that "lesser" monkeys can learn the concept of "self" as well, even using mirrors to become familiar with their own bodies.
