Monkey is a common name that may refer to most mammals of the infraorder Simiiformes, also known as the simians. Traditionally, all animals in the group now known as simians are counted as monkeys except the apes, a grouping known as paraphyletic; however in the broader sense based on cladistics, apes (Hominoidea) are also included, making the terms monkeys and simians synonyms in regard of their scope. Monkeys are divided into the families of New World monkeys (Platyrrhini) and Old World monkeys (Cercopithecidae in the strict sense; Catarrhini in the broad sense, which again includes apes).
Many monkey species are tree-dwelling (arboreal), although there are species that live primarily on the ground, such as baboons. Most species are mainly active during the day (diurnal). Monkeys are generally considered to be intelligent, especially the Old World monkeys.
Simians and tarsiers, the two members of the suborder Haplorhini, emerged some 60 million years ago. New World monkeys and catarrhine monkeys emerged within the simians some 35 million years ago. Old World monkeys and apes emerged within the catarrhine monkeys some 25 million years ago. Extinct basal simians such as Aegyptopithecus or Parapithecus [35–32 million years ago] are also considered monkeys by primatologists.
Lemurs, lorises, and galagos are not monkeys; instead they are strepsirrhine primates (suborder Strepsirrhini). The simians' sister group, the tarsiers are also haplorhine primates; however, they are also not monkeys.
Apes emerged within "monkeys" as sister of the Cercopithecidae in the Catarrhini, so cladistically they are monkeys as well. There has been resistance to directly designate apes (and thus humans) as monkeys, so "Old World monkey" may be taken to mean either the Cercopithecoidea (not including apes) or the Catarrhini (including apes). That apes are monkeys was already realized by Georges-Louis Leclerc, Comte de Buffon in the 18th century.
Monkeys, including apes, can be distinguished from other primates by having only two pectoral nipples, a pendulous penis, and a lack of sensory whiskers.
