Chimpanzees may react to lions by fleeing up trees, vocalising, or hiding in silence. [82] The chimpanzee louse Pediculus schaeffi is closely related to the human body louse P. humanus. Chimpanzees and humans share only 50% of their parasite and microbe species. This is due to the differences in environmental and dietary adaptations; human ...
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 ...
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 first South American primates gave rise to an impressive evolutionary radiation: more than 120 species in five families. These primates are known as platyrrhine (flat-nosed) primates and are closely related to Old World apes and monkeys (catarrhine primates).
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 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.
Sometimes, chimpanzees have adopted young that come from unrelated groups. And in some rare cases, even male chimpanzees have been shown to take care of abandoned infant chimpanzees of an unrelated group, though in most cases they would kill the infant.
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.
