Extinct members of the order of mammals to which humans belong. All current classifications divide the living primates into two major groups (suborders): the Strepsirhini or “lower” primates (lemurs, lorises, and bushbabies) and the Haplorhini or “higher” primates [tarsiers and anthropoids (New and Old World monkeys, greater and lesser apes, and humans)]. Some fossil groups (omomyiforms and adapiforms) can be placed with or near these two extant groupings; however, there is contention whether the Plesiadapiformes represent the earliest relatives of primates and are best placed within the order (as here) or outside it.
