A primate is an animal belonging to the biological order Primates, the group that contains all the species commonly related to the monkeys, apes (including humans), and lemurs. All primates have five fingers, a generalized dental pattern, and an unspecialized body plan. Other distinguishing features of primates are fingernails, opposable thumbs, and long, inward-closing fingers.
