Comparison of size of adult chimpanzee and adult human. The chimpanzee is tailless; its coat is dark; its face, fingers, palms of the hands, and soles of the feet are hairless. The exposed skin of the face, hands, and feet varies from pink to very dark in both species, but is generally lighter in younger individuals and darkens with maturity.
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.
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]
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 ...
Kanzi, a 33-year-old bonobo, was born and raised the United States. The bonobo lives at the Primate Learning Sanctuary in Iowa and has grown up in a bi-cultural world of bonobos and humans.
Humans and chimpanzees share similar ticklish areas of the body such as the armpits and belly. [ 6 ] Research has noted the similarity in forms of laughter among humans and other apes ( chimpanzees , gorillas and orangutans ) when tickled, suggesting that laughter derived from a common origin among primate species, and therefore evolved prior ...
