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 ...
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 ...
Unlike animals that have litters or lay eggs, primates are similar to humans in that they deliver one baby at a time. Increasing numbers is a long, tedious game spanning decades.
"Ape" has been used as a synonym for "monkey" or for naming any primate with a human-like appearance, particularly those without a tail. [10] Biologists have traditionally used the term "ape" to mean a member of the superfamily Hominoidea other than humans, [4] but more recently to mean all members of Hominoidea.
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 ...
Traditionally, chimpanzees, gorillas and orangutans were grouped together, excluding humans, as pongids.Since Gray's classifications, evidence accumulating from genetic phylogeny confirmed that humans, chimpanzees, and gorillas are more closely related to each other than to the orangutan. [3]
Ethnoprimatology is a discourse aimed at an anthropological holistic understanding of non-human primates. Human cultures worldwide have deep-rooted, primordial connections with non-human primates. Non-human primates play key roles in creation stories of many societies and often depict the direct relationship between non-human primates and humans.
