Chimpanzee and bonobo males A comparison of chimpanzees' and bonobos' performance on various cognitive tests [142] In 2020, the first whole-genome comparison between chimpanzees and bonobos was published and showed genomic aspects that may underlie or have resulted from their divergence and behavioral differences , including selection for genes ...
Bonobos frequently have sex, sometimes to help prevent and resolve conflicts. Different groups of chimpanzees also have different cultural behaviour with preferences for types of tools. [52] The common chimpanzee tends to display greater aggression than does the bonobo. [53] The average captive chimpanzee sleeps 9 hours and 42 minutes per day. [54]
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 ...
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 ...
They comprise two extant genera: Homo and Pan (chimpanzees and bonobos), and in standard usage exclude the genus Gorilla , which is grouped separately within subfamily Homininae. The term Hominini was originally introduced by Camille Arambourg (1948), who combined the categories of Hominina and Simiina pursuant to Gray 's classifications (1825).
Chimpanzees lack the prominent sagittal crest and associated head and neck musculature of gorillas. [14] [39] 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.
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.
In the past, bonobos were incorrectly relegated to subspecies status within the species chimpanzee. It is now understood that bonobos are an entirely different species. After Pan paniscus was differentiated and named as a new species to science, "bonobo" developed into its accepted common name. As bonobos aren't chimpanzees, old common names ...
