Apes

Apes are a group of primates that includes gorillas, orang-utans, chimpanzees, and gibbons. These are the primate species that are the most closely related to humans. The hands, feet, and face of an ape are hairless, while the rest of its body is covered with coarse black, brown, or red hair. Apes share some characteristics that set them apart from other primates: they have an appendix, lack a tail, and their skeletal structures have certain features not found in the skeletons of other primates.
