what is chimpanzee

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. Chimpanzees are unable to swim, but they will wade in water. [159] At least six cases of chimpanzees snatching and eating human babies are documented. Ayumu performed better than human adults who were given the same test. Young chimpanzees learn from observing their mothers and other adults … Movement over any significant distance usually takes place on the ground. Chimpanzees are lively animals with more extraverted dispositions than either gorillas or orangutans. Both males and females sometimes travel alone. Other mammalian prey include red-tailed monkeys, infant and juvenile yellow baboons, bush babies, blue duikers, bushbucks, and common warthogs. [110] Chimps also display signs of culture among groups, with the learning and transmission of variations in grooming, tool use and foraging techniques leading to localised traditions. [13], DNA evidence suggests the bonobo and chimpanzee species separated from each other less than one million years ago (similar in relation between Homo sapiens and Neanderthals). In the trees, where most feeding takes place, chimps use their hands and feet to move about. [46] The chimpanzee makes a night nest in a tree in a new location every night, with every chimpanzee in a separate nest other than infants or juvenile chimpanzees, which sleep with their mothers. [47], The chimpanzee is an omnivorous frugivore. The hair of a chimp is typically black but can be brown or ginger. The chimpanzee is a great ape species that is native to sub-Saharan Africa, where it prefers forests and jungles. Individuals vary considerably in size and appearance, but chimpanzees stand approximately 1–1.7 metres (3–5.5 feet) tall when erect and weigh about 32–60 kg (70–130 pounds). Many attempts have been made to teach languages such as American Sign Language to chimpanzees, with limited success. Instances in which nonhuman primates have expressed joy have been reported. Nevertheless, the status of an adult female may be important for her offspring. [32] In exceptional cases, certain individuals may considerably exceed these measurements, standing over 168 cm (5 feet, 6 inches) on two legs and weighing up to 136 kg (300 pounds) in captivity. The Dutch ministry of science decided to phase out research at the centre from 2001. [152], Jane Goodall undertook the first long-term field study of the chimpanzee, begun in Tanzania at Gombe Stream National Park in 1960. West African chimps crack open hard nuts with stones or branches. There are three main factors affecting chimpanzee populations and they all directly relate to human activity. Look at conditions in your waking life from a distance for perspective. It is larger and more robust than the bonobo, weighing 40–70 kg (88–154 lb) for males and 27–50 kg (60–110 lb) for females and standing 150 cm (4 ft 11 in). & Sanz, C.", "Advancing conservation planning for western chimpanzees using IUCN SSC A.P.E.S.—the case of a taxon-specific database", "Regional action plan for the conservation of the Nigeria-Cameroon chimpanzee (Pan troglodytes ellioti)", "Pan troglodytes ssp. Chimpanzees are very familiar to us humans, perhaps because so much of their behavior reminds us of ourselves. By contrast, the human pubic louse Pthirus pubis is closely related to Pthirus gorillae which infests gorillas. [16] The chimpanzee line split from the last common ancestor of the human line around six million years ago. Humans and chimpanzees share similar ticklish areas of the body, such as the armpits and belly. [115], Experimenters, however, now and then witness behaviour that cannot be readily reconciled with chimpanzee intelligence or theory of mind. Baby chimps are also taken from their mothers and sold as pets. [86][80] While it was traditionally accepted that only female chimpanzees immigrate and males remain in their natal troop for life, there are confirmed cases of adult males safely integrating themselves into new communities among West African chimpanzees, suggesting they are less territorial than other subspecies. They use sticks to fish for insects, poking the twigs into the holes of ant or termite mounds and pulling them out, covered with wiggling food. Chimps are promiscuous; during oestrus, females mate with several males in their community, while males have large testicles for sperm competition. Juveniles remain close to their mothers, but interact an increasing amount with other members of their community. [58][60], The average lifespan of a chimpanzee in the wild is relatively short, usually less than 15 years, although individuals that reach 12 years may live an additional 15. [151], Chimpanzees including the female Ai have been studied at the Primate Research Institute of Kyoto University, Japan, formerly directed by Tetsuro Matsuzawa, since 1978. Because no species other than Homo sapiens has survived from the human line of that branching, both chimpanzee species are the closest living relatives of humans; the lineage of humans and chimpanzees diverged from gorillas (genus Gorilla) about seven million years ago. Chimpanzee appearing in your dreams suggests what you think is the truth is not actually the truth. Chimpanzee. [104] Male chimps hunt more than females. Lions and leopards also prey upon chimpanzees. A community can number from 20 or fewer to well over 100 members. Chimps lack the prominent sagittal crest and associated head and neck musculature of gorillas. When they reach two years of age, they are able to move and sit independently, and start moving beyond the arms reach of their mothers. [168], The biggest threats to the chimpanzee are habitat destruction, poaching, and disease. & Pintea, L.", "Initial sequence of the chimpanzee genome and comparison with the human genome", "Bipedal tool use strengthens chimpanzee hand preferences", "Inhibition of endotoxin-induced activation of coagulation and fibrinolysis by pentoxifylline or by a monoclonal anti-tissue factor antibody in chimpanzees", "Independent evolution of knuckle-walking in African apes shows that humans did not evolve from a knuckle-walking ancestor", "Chimpanzee super strength and human skeletal muscle evolution", "The Tai Chimpanzee Project in Cote d'Ivoire, West Africa", "Feeding ecology of chimpanzees in the Kibale Forest, Uganda", "The Predatory Behavior and Ecology of Wild Chimpanzees", "Africa's Oldest Chimp, a Conservation Icon, Dies", "An Encounter between a leopard and a group of chimpanzees at Gombe National Park", "Gastrointestinal parasite infections and self-medication in wild chimpanzees surviving in degraded forest fragments within an agricultural landscape mosaic in Uganda", "Variation in hunting behaviour in neighbouring chimpanzee communities in the Budongo forest, Uganda", "Agonistic behavior, dominance, and social structure in wild chimpanzees of the Gombe National Park", "The Rise and Fall of a Chimpanzee Matriarchy - Przekrój Magazine", "Reciprocity and interchange in the social relationships of wild male chimpanzees", "Chimpanzee females queue but males compete for social status", "Trade-offs in the production of animal vocal sequences: insights from the structure of wild chimpanzee pant hoots", "How chimpanzees cooperate in a competitive world", "Behavioural Diversity among the Wild Chimpanzee Populations of Bossou and Neighbouring Areas, Guinea and Côte d'Ivoire, West Africa", "Pestle-pounding and nut-cracking by wild chimpanzees at Kpala, Liberia", "Chimpanzees using stones to crack open oil palm nuts in Liberia", "Chimpanzees (Pan troglodytes) and the question of cumulative culture: an experimental approach", "Complex tool sets for honey extraction among chimpanzees in Loango National Park, Gabon", "Chimpanzees routinely fish for algae with tools during the dry season in Bakoun, Guinea", "4,300-year-old chimpanzee sites and the origins of percussive stone technology", "Female Chimps Seen Making, Wielding Spears", "PG Tips chimps: The last of the tea-advertising apes", "Chimpanzee Research: Overview of Research Uses and Costs". A draft version of the chimpanzee genome was published on 1 September 2005 by the Chimpanzee Sequencing and Analysis Consortium. The bonobo was recognised as distinct from the chimpanzee by 1933. [82] Social grooming appears to be important in the formation and maintenance of coalitions. Until then, chimpanzees were believed to be herbivores, like most other great apes. [54], Despite the fact that chimpanzees are known to hunt, and to collect insects and other invertebrates, such food actually makes up a very small portion of their diet, from as little as 2% yearly to as much as 65 grams of animal flesh per day for each adult chimpanzee in peak hunting seasons. [8][9], The first great ape known to Western science in the 17th century was the "orang-outang" (genus Pongo), the local Malay name being recorded in Java by the Dutch physician Jacobus Bontius. The most prevalent species was the protozoan Troglodytella abrassarti. The species has also been found creating sharpened sticks to spear small mammals. [7] The genus name Pan derives from the Greek god, while the specific name troglodytes was taken from the Troglodytae, a mythical race of cave-dwellers.

[105], In controlled experiments on cooperation, chimpanzees show a basic understanding of cooperation, and recruit the best collaborators. They are also taken, often illegally, for the pet trade, and are hunted for medicinal purposes in some areas. Although chimps take care of orphaned infants, they also tease handicapped individuals, conceal information that would bring disadvantage to themselves, and manipulate others for their own advantage by expressing deceptive postures, gestures, and facial expressions. Chimpanzee habitats have been limited by deforestation in both West and Central Africa. Each consists of several subgroups of varying size and unstable composition. Female chimpanzees spend most of their time with their young or with other females. [49][55] Female chimpanzees appear to consume much less animal flesh than males, according to several studies. Relations between different chimp communities tend to be hostile. "Drivers" serve to keep the prey running in a certain direction and follow them without attempting to make a catch. Although deforestation rates are low in western Central Africa, selective logging may take place outside national parks. Chimpanzees mate throughout the year, although the number of females in oestrus varies seasonally... Communication. [66] Four chimpanzees could have fallen prey to lions at Mahale Mountains National Park. The bonobo is found only in lowland rainforests along the south bank of the Congo River in the Democratic Republic of the Congo. Take advantage of our Presidents' Day bonus! [140] Outside their range, chimpanzees are popular as exotic pets despite their strength and aggression. As they get older, white or grey patches may appear, particularly on the chin and lower region. In one case chimps cared for a dying elder, then attended and cleaned the corpse.

[88] Female chimps are more likely to come into oestrus when food is readily available. A male and female can form a consortship and mate outside their community. In addition, females sometimes leave their community and mate with males from neighboring communities. Afterward, they avoided the spot where the elder died and behaved in a more subdued manner. [35] As a result, individual chimpanzees often forage for food alone, or in smaller groups as opposed to the much larger "parent" group, which encompasses all the chimpanzees which regularly come into contact and congregate into parties in a particular area.
