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.
The chimpanzee–human last common ancestor (CHLCA) is the last common ancestor shared by the extant Homo (human) and Pan (chimpanzee and bonobo) genera of Hominini.Estimates of the divergence date vary widely from thirteen to five million years ago.
The bonobo was recognised as distinct from the chimpanzee by 1933. [11] ... HIV-2 occurs mostly in west Africa. [187] Both types originated in west and central Africa
Native to sub-Saharan Africa, chimpanzees and bonobos are currently both found in the Congo jungle, while only the chimpanzee is also found further north in West Africa. Both species are listed as endangered on the IUCN Red List of Threatened Species , and in 2017 the Convention on Migratory Species selected the chimpanzee for special protection.
Australopithecus fossils become more widely dispersed throughout eastern and southern Africa (the Chadian A. bahrelghazali indicates that the genus was much more widespread than the fossil record suggests), before eventually becoming pseudo-extinct 1.9 million years ago (or 1.2 to 0.6 million years ago if Paranthropus is included).
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 ...
Possible evidence for a third transatlantic dispersal event comes from a fossil molar belonging to Ashaninkacebus simpsoni, which has strong affinities with stem anthropoid primates of South Asian origin, the Eosimiidae. [11] The chromosomal content of the ancestor species appears to have been 2n = 54. [12]
