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 ...
As a rule, primate brains are "significantly larger" than those of other mammals with similar body sizes. [4] Until well into the 19th century, juvenile orangutans were taken from the wild and died within short order, eventually leading naturalists to mistakenly assume that the living specimens they briefly encountered and skeletons of adult ...
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 Asia.
Sumatran orangutan (Pongo abelli) Hominoidea is a superfamily of primates. Members of this superfamily are called hominoids or apes, and include gorillas, chimpanzees, orangutans, gibbons, bonobos, and humans. Hominoidea is one of the six major groups in the order Primates. The majority are found in forests in Southeastern Asia and Equatorial Africa, with the exception of humans, which have ...
One of the 25 most endangered primates. [7] Delacour's langur: Trachypithecus delacouri: 234–275 [8] CR [8] [8] The population of the species has radically decreased over the past decade. [8] Silky sifaka: Propithecus candidus: 250 [9] CR [9] [9] Estimate is believed to be a maximum. [9] Tonkin snub-nosed monkey: Rhinopithecus avunculus: 250 ...
Being an evolutionary grade rather than a clade, the prosimians are united by being primates with traits otherwise found in non-primate mammals. Their diets typically are less dominated by fruit than those of the simians, and many are active arboreal predators, hunting for insects and other small animals in the trees. [ 5 ]
The divergence of a "proto-human" or "pre-human" lineage separate from Pan appears to have been a process of complex speciation-hybridization rather than a clean split, taking place over the period of anywhere between 13 Mya (close to the age of the tribe Hominini itself) and some 4 Mya.
The earliest anthropoids were small primates with varied diets, forward-facing eyes, acute color vision for daytime lifestyles, and brains devoted more to vision and less to smell. [6] Living simians in both the New World and the Old World have larger brains than other primates, but they evolved these larger brains independently. [6]
