An adaptive or evolutionary grade among the primates, with representatives divided into Old World and New World groups. The term monkey is not indicative of a taxonomic or phylogenetic relationship. Instead, it is a common name used to describe any of the nonhuman primate mammals categorized into Old World and New World species. The extant Old World or catarrhine monkeys belong to the superfamily Cercopithecoidea in the parvorder Catarrhini (note that the other superfamily in this parvorder is Hominoidea, which comprises apes and humans), whereas the extant New World or platyrrhine monkeys (Fig. 1) are assigned to the superfamily Ceboidea in the parvorder Platyrrhini. The Old World and New World forms probably reached a monkey level of adaptation independently some time after their separation from a common ancestor, perhaps 45–55 million years ago (MYA).
