Prosimians contain two monophyletic groups (the suborder Strepsirrhini, or lemurs, lorises and allies, as well as the tarsiers of the suborder Haplorhini); it is a paraphyletic grouping because it excludes the Simiiformes, which also are descendants of the common ancestor Primates. Monkeys comprise two monophyletic groups, New World monkeys and ...
The order Primates consists of 505 extant species belonging to 81 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 81 genera can be grouped into 16 families; these families are divided between two named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named ...
The prosimians were once a group considered a suborder of the primate order (suborder Prosimii - Gr. pro, before, + Latin simius/simia, ape), which was named in 1811 by Johann Karl Wilhelm Illiger. They have been shown, however, to be paraphyletic - that is, their most recent common ancestor was a prosimian but it has some non-prosimian ...
The Hominidae (/ h ɒ ˈ m ɪ n ɪ d iː /), whose members are known as the great apes [note 1] or hominids (/ ˈ h ɒ m ɪ n ɪ d z /), are a taxonomic family of primates that includes eight extant species in four genera: Pongo (the Bornean, Sumatran and Tapanuli orangutan); Gorilla (the eastern and western gorilla); Pan (the chimpanzee and the bonobo); and Homo, of which only modern humans ...
These first primates included Cantius, Donrussellia, Altanius, and Teilhardina on the northern continents, [30] as well as the more questionable (and fragmentary) fossil Altiatlasius from Paleocene Africa. [19] These earliest fossil primates are often divided into two groups, adapiforms [d] and omomyiforms.
The origin of anthropoid primates was initially thought to be Africa, however, fossil evidence, now suggests they originated in Asia. During the middle to late Eocene, multiple groups of Asian anthropoids crossed the Tethys Sea on natural rafts or floating islands, colonizing Africa alongside other Asian mammals. The earliest African anthropoid ...
A primate is a member of the biological order Primates, the group that contains lemurs, the aye-aye, lorisids, galagos, tarsiers, monkeys, and apes, with the last category including great apes. With the exception of humans, who inhabit every continent on Earth, most primates live in tropical or subtropical regions of the Americas , Africa and ...
Linnaeus placed this group in 1758 together with what we now recognise as the tarsiers and the New World monkeys, in a single genus "Simia" (sans Homo). [15] The Catarrhini are all native to Africa and Asia. Members of this parvorder are called catarrhines. The Catarrhini are the sister group to the New World monkeys, the Platyrrhini.
