Existing chimpanzee populations in West and Central Africa do not overlap with the major human fossil sites in East Africa, but chimpanzee fossils have now been reported from Kenya. This indicates that both humans and members of the Pan clade were present in the East African Rift Valley during the Middle Pleistocene .
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. They can live over 30 years in both the wild and captivity.
Male chimpanzee with his prey, a bushbuck. Chimpanzees are omnivorous and eat seeds, fruits, honey, leaves, bark, fungi, insects such as termites, ants and small prey such as birds and monkeys. They often use a twig as a tool to reach termites or ants in nests and have been seen using sticks to hunt other small mammals. There are also instances ...
All species are omnivorous, [26] although chimpanzees and orangutans primarily eat fruit. When gorillas run short of fruit at certain times of the year or in certain regions, they resort to eating shoots and leaves, often of bamboo, a type of grass. Gorillas have extreme adaptations for chewing and digesting such low-quality forage, but they ...
The bonobo (/ b ə ˈ n oʊ b oʊ, ˈ b ɒ n ə b oʊ /; Pan paniscus), also historically called the pygmy chimpanzee (less often the dwarf chimpanzee or gracile chimpanzee), is an endangered great ape and one of the two species making up the genus Pan (the other being the common chimpanzee, Pan troglodytes). [4]
Chimpanzees often eat the marrow of long bones of colobus monkeys with the help of small sticks, after opening the ends of the bones with their teeth. [39] A juvenile female was observed to eat small parts of the brain of an intact skull that she could not break open by inserting a small stick through the foramen magnum. On another occasion, an ...
Each chimp is provided with a fresh stash of hay each day so that they can build an intricate nest to fall asleep in — a behavior chimps engage in in the wild. While they may see the care staff ...
Apart from humans and gorillas, apes eat a predominantly frugivorous diet, mostly fruit, but supplemented with a variety of other foods. Gorillas are predominantly folivorous, eating mostly stalks, shoots, roots and leaves with some fruit and other foods. Non-human apes usually eat a small amount of raw animal foods such as insects or eggs.
