Great Apes diverged from Lesser Apes about 20 million years ago. Apes have unique characteristics that separate them from monkey, the most obvious one being the lack of a tail. They also have an appendix, a wide and shallow chest, a shoulder structure that allows the arm to rotate freely, and the most complex brain among primates. They are usually larger with a more upright posture that allows some of them them to walk on two legs. It is the ball and socket joint in their shoulder that allows apes and monkeys to swing in trees. Great apes are more intelligent with the ability to use tools, use language, and have complex social lives. The oldest known great apes is the Pierolapithecus catalaunicus, which lived 12 million years ago. It was 77 pounds, ate berries, and may have stood
