<P> Simians are divided into two groups : catarrhine ( narrow - nosed ) monkeys and apes of Africa and Southeast Asia and platyrrhine ( `` flat - nosed '' ) or New World monkeys of South and Middle America . Catarrhines consist of Old World monkeys ( such as baboons and macaques ) , gibbons and great apes ; New World monkeys include the capuchin , howler and squirrel monkeys . Humans are the only extant catarrhines to have spread successfully outside of Africa , South Asia , and East Asia , although fossil evidence shows many other species were formerly present in Europe . New primate species are still being discovered . More than 25 species were taxonomically described in the decade of the 2000s and eleven have been described since 2010 . </P>
