New World monkeyNew World monkeys are the five families of primates that are found in the tropical regions of Mexico, Central and South America: Callitrichidae, Cebidae, Aotidae, Pitheciidae, and Atelidae. The five families are ranked together as the Ceboidea (), the only extant superfamily in the parvorderPlatyrrhini (). Platyrrhini is derived from the Greek for "broad nosed", and their noses are flatter than those of other simians, with sideways-facing nostrils.
CatarrhiniThe parvorderCatarrhini (known commonly as catarrhine monkeys, Old World anthropoids, or Old World monkeys) consists of the Cercopithecoidea (Old World monkeys) and Hominoidea (apes). In 1812, Geoffroy grouped those two groups together and established the name Catarrhini, "Old World monkeys" (singes de l'Ancien Monde in French). Its sister in the infraorder Simiiformes (simians) is the parvorder Platyrrhini (New World monkeys).
SimianThe simians, anthropoids, or higher primates (simian from Latin: simis, lit.'monkey') are primates of the infraorderSimiiformes (), containing all animals traditionally called monkeys and apes. More precisely, they consist of the parvorders Platyrrhini (New World monkeys) and Catarrhini, the latter of which consists of the family Cercopithecidae (Old World monkeys in the stricter sense) and the superfamily Hominoidea (apes – including humans).
ApeApes, collectively Hominoidea (; hominoids), are a superfamily of Old Worldsimians native to sub-Saharan Africa and Southeast Asia. They were more widespread in Africa, Asia, and Europe in prehistory, and, including humans, are found globally. Apes are more closely related to Old World monkeys (family Cercopithecidae) than to the New World monkeys (Platyrrhini), with both Old World monkeys and apes placed in the cladeCatarrhini.
Old World monkeyOld World monkeys are primates in the family Cercopithecidae (). Twenty-four genera and 139 species are recognized, making it the largest primate family. Old World monkey genera include baboons (genus Papio), red colobus (genus Piliocolobus), and macaques (genus Macaca).
ParaphylyParaphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic with respect to the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and all of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics.
Arboreal locomotionArboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally (scansorial), but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species.
French languageFrench (français or langue française) is a Romance language of the Indo-European family. Like all other Romance languages, French and its closest relatives—the langues d'oïl, historically spoken in northern France and southern Belgium—descended from the Vulgar Latin of the Roman Empire. It was influenced by native Celtic languages of Northern Roman Gaul and by the GermanicFrankish language of the post-Roman Frankish invaders.
Étienne Geoffroy Saint-HilaireÉtienne Geoffroy Saint-Hilaire (French pronunciation:; 15 April 1772 – 19 June 1844) was a French naturalist who established the principle of "unity of composition". He was a colleague of Jean-Baptiste Lamarck and expanded and defended Lamarck's evolutionary theories. Geoffroy's scientific views had a transcendental flavor (unlike Lamarck's materialistic views) and were similar to those of German morphologists like Lorenz Oken.
Order (taxonomy)Order (Latin: ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. Like the other ranks, orders reflect shared ancestry; for example, all owls belong to the order Strigiformes. In biological classification systems, orders and their usage are defined by nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order.*As an Amazon Associate I earn from qualifying purchases.
