Primates Linnaeus, 1758

Mammalian order to which the lemurs, bushbabies, lorises, tarsiers, monkeys, apes, and humans belong. There is no one characteristic that defines the order; rather, a suite of characters (sometimes listed as evolutionary trends) that include possession of nails, grasping paws with opposable thumb and great toe, binocular vision, and a relatively large brain. The order contains more than 200 extant species. Undoubted members of the order first appear in the fossil record during the Eocene.

See Prosimii, Strepsirhini, Anthropoidea, Haplorhini, and Tarsioidea.
