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.
Both chimpanzees and bonobos are some of the most social great apes, with social bonds occurring throughout large communities. Fruit is the most important component of a chimpanzee's diet; but they will also eat vegetation, bark, honey, insects and even other chimpanzees or monkeys.
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.
Chimpanzees, and the closely related bonobos, are the species nearest genetically to humans, sharing about 98.8% of our DNA. The human and chimpanzee evolutionary lineages split about 6.9 million ...
In the study, scientists worked with 26 chimpanzees and bonobos living in sanctuaries in Japan and Europe. They showed the apes two photos at a time — one of a familiar face and one of a stranger.
Our closest animal relatives are capable of remembering former groupmates they haven't seen in years, or even decades, researchers report.
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.
According to Meinelt, it was an intentional decision by zoo officials to bring in bonobos rather than chimpanzees, recognizing the need to raise awareness about the lesser-known species and to ...
