Prosimians are characterized by their rather primitive features compared with those of simians. A more recent classification of primates shows that the primates may be grouped into wet-nosed primates and dry-nosed primates. Whereas all other mammals have claws or hooves on their digits, only primates have flat nails.


The order Primates, with its 300 or more species, is the third most diverse order of mammals, after rodents (Rodentia) and bats (Chiroptera). Again, this feature is not by any means restricted to primates, but it is a general feature seen among predators.

Fossils of the earliest primates date to the Early Eocene Epoch (56 million to 40 million years ago) or perhaps to the Late Paleocene Epoch (59 million to 56 million years ago). Primate teeth are distinguishable from those of other mammals by the low, rounded form of the molar and premolar cusps, which contrast with the high, pointed cusps or elaborate ridges of other placental mammals.
