Molecular evidence indicates that the lineage of gibbons (family Hylobatidae) diverged from Great Apes some 18–12 million years ago, and that of orangutans (subfamily Ponginae) diverged from the other Great Apes at about 12 million years; there are no fossils that clearly document the ancestry of gibbons, which may have originated in a so-far ...
Chimpanzees lack the prominent sagittal crest and associated head and neck musculature of gorillas. [14] [41] Chimpanzee hand (left) compared to human hand. Chimpanzee bodies are covered by coarse hair, except for the face, fingers, toes, palms of the hands, and soles of the feet. Chimpanzees lose more hair as they age and develop bald spots.
Apes: great apes and lesser apes : 22–20 Family: Hominidae: Great apes: humans, chimpanzees, gorillas and orangutans—the hominids: 20–15 Subfamily: Homininae: Humans, chimpanzees, and gorillas (the African apes) [1] 14–12 Tribe: Hominini: Includes both Homo and Pan (chimpanzees), but not Gorilla. 10–8 Subtribe: Hominina
The hominoids are descendants of a common ancestor.. Homo sapiens is a distinct species of the hominid family of primates, which also includes all the great apes. [1] Over their evolutionary history, humans gradually developed traits such as bipedalism, dexterity, and complex language, [2] as well as interbreeding with other hominins (a tribe of the African hominid subfamily), [3] indicating ...
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 ...
The Old World species are divided into apes and monkeys depending on the number of cusps on their molars: monkeys have four, apes have five [72] - although humans may have four or five. [78] The main hominid molar cusp ( hypocone ) evolved in early primate history, while the cusp of the corresponding primitive lower molar (paraconid) was lost.
Formerly the bonobo was known as the "pygmy chimpanzee", despite the bonobo having a similar body size to the common chimpanzee. The name "pygmy" was given by the German zoologist Ernst Schwarz in 1929, who classified the species on the basis of a previously mislabeled bonobo cranium, noting its diminutive size compared to chimpanzee skulls.
[6] [7] At the time the New World monkeys dispersed to South America, the Isthmus of Panama had not yet formed, so ocean currents, unlike today, favoured westward dispersal, the climate was quite different, and the width of the Atlantic Ocean was less than the present 2,800 km (1,700 mi) width by about a third (possibly 1,000 km (600 mi) less ...
