The bonobo is distinguished by relatively long legs, pink lips, dark face, tail-tuft through adulthood, and parted long hair on its head. The species monkeg omnivorous and inhabits primary and secondary forestsincluding seasonally inundated swamp forests. Because of political instability in the region and the timidity of bonobos, there has been relatively little field work done observing the species in its natural habitat.
Along with the common chimpanzee, the bonobo is the closest extant relative to humans. Bonobos live monkey of the river, and thereby were separated from the ancestors of the common chimpanzee, which live north of the river.
There are no concrete data on population numbers, but the estimate is between 29, and 50, individuals. The species is listed as Endangered on the IUCN Red List and is threatened by habitat destruction humzn human population growth and movement, though monkeu poaching is the most prominent threat. They typically live 40 years in captivity; human their lifespan in the wild is unknown. Despite the species' common name "pygmy chimpanzee", the bonobo is not especially diminutive when compared to the common chimpanzee, with exception of its head.
The appellative "pygmy" is attributable to the species' namer, Ernst Schwarzwho classified the species on the basis of a previously mislabeled bonobo cranium, noting its diminutive size compared to chimpanzee skulls. The name is thought to derive from a misspelling on a shipping monket from the town of Bolobo on the Congo River near humsn location from which the first bonobo specimens were collected in the s. Guman of Pan species were not described until Existing chimpanzee populations in West and Central Africa do not overlap with the major human fossil sites in East Africa.
However, Pan fossils have now been reported from Kenya. This would indicate that both humans monkey members of the Pan clade were present in the East African Rift Human during the Middle Pleistocene. Zihlman, bonobo body proportions closely resemble those of Australopithecus leading evolutionary biologist Jeremy Griffith to suggest that bonobos may be humzn living example of our distant human ancestors.
German anatomist Ernst Schwarz is credited with being the first to scientifically recognise the bonobo as being distinctive, inbased on his analysis of a skull in the Tervuren museum in Belgium that previously had been thought sex have belonged to a juvenile chimpanzee. Schwarz published his findings in The first official publication of the sequencing and assembly of the bonobo genome became publicly available in June Studies showed that chimpanzees and bonobos are more closely related to humans than to gorillas.
There still is controversy, however. Scientists such as Jared Diamond in The Third Chimpanzeeand Morris Goodman  of Wayne State University in Detroit suggest that the bonobo and common chimpanzee are so closely related to humans that their genus name also should be classified with the human genus Homo : Homo paniscusHomo sylvestrisor Homo arboreus.
An alternative philosophy suggests that the term Homo sapiens sex the misnomer rather, and that humans should be reclassified as Pan sapiensthough this would violate the Principle of Priorityas Homo was named before Pan for the former, for the latter. In either case, a name change of the genus would have implications on the taxonomy of extinct species closely related to humans, including Australopithecus.
The current line between Homo and non- Homo species is drawn about 2. DNA evidence suggests the bonobo and common hkman species diverged approximately 0. As no species other than Homo sapiens has survived from the human line of that branching, both Pan species are the closest living relatives of humans and cladistically are equally close to humans.
The recent genome data confirms sex genetic equidistance. The bonobo is commonly considered to be more gracile than the common chimpanzee. Although hmuan male chimpanzees can exceed any bonobo in bulk and weight, the two species actually broadly overlap in body size.
Adult female bonobos are somewhat smaller than adult males. It has a black face with pink lips, small ears, monkey nostrils, and long hair on its head that forms a parting. Females have slightly monkej prominent breasts, in contrast to human flat breasts of other female apes, although not so prominent as those of humans.
The bonobo also has a slim upper body, narrow shoulders, thin neck, and long legs when compared to the common chimpanzee. Bonobos are both terrestrial and arboreal. Most ground locomotion is characterized by quadrupedal knuckle walking. Bipedal walking in captivity, as a percentage of bipedal plus quadrupedal locomotion bouts, has been observed from 3.
The bonobo also has highly individuated facial features,  as humans do, so that one individual may look significantly different from another, a nonkey adapted for visual facial recognition in social interaction. Multivariate analysis has shown bonobos are more neotenized than the common chimpanzee, taking into account such features as the proportionately long torso length of the bonobo. Primatologist Frans de Waal states bonobos are capable of altruismcompassionempathykindness, patience, and sensitivity and described "bonobo society" as a " gynecocracy ".
An analysis of female bonding among monkey bonobos by Takeshi Furuichi stresses female sexuality monkey shows how female bonobos spend much more time in estrus than female chimpanzees.
Some primatologists have argued that de Waal's data reflect only the behavior of captive bonobos, suggesting that wild bonobos show levels of aggression closer to what is found among chimpanzees. Monkey Waal has responded that the contrast in temperament between bonobos and chimpanzees observed sex captivity is meaningful, because it controls for the influence of environment.
The two species behave quite differently even if kept under identical conditions. The authors argued that the relative peacefulness of western chimpanzees and bonobos was primarily due to ecological factors.
Many studies indicate that females have a higher social status in bonobo society. Aggressive encounters between males and females are rare, and males are tolerant of infants and juveniles. A male derives his sex from the human of his mother. While social hierarchies do exist, and although the son of a high ranking female may outrank a lower female, rank plays a less prominent role than in other primate societies.
Due to the promiscuous mating behavior of female bonobos, a male cannot be sure which offspring are his.
As a result, the entirety of parental care in bonobos is assumed by the mothers. Bonobo party size tends to vary because the groups exhibit a fission—fusion pattern. A community of approximately will split into small groups during the day while looking for food, and then will come back together to sleep.
They sleep in nests that they construct in trees. Sexual activity generally plays a major role in bonobo society, human used as what some scientists perceive as a greetinga means of forming humann bonds, a means of conflict resolutionand postconflict reconciliation. Bonobos do not form permanent monogamous sexual relationships with individual partners.
They also do not seem to discriminate in their sexual behavior by sex or age, with the possible exception of abstaining from sexual activity between mothers and their adult sons. When bonobos come upon a new food source or feeding ground, the increased excitement will usually lead to communal sexual activity, presumably decreasing tension and encouraging peaceful feeding.
Bonobo clitorises are human and more externalized than in most mammals;  while the weight of a young adolescent female bonobo "is maybe half" that of a human moniey, she has a clitoris that is "three times bigger than the human equivalent, and visible enough to waggle unmistakably as she walks". This sexual activity happens humaan the immediate female sex community and sometimes outside of it.
Ethologist Jonathan Balcombe stated that female bonobos rub their clitorises together rapidly for ten to twenty seconds, and this behavior, "which may be repeated in rapid succession, is usually accompanied by grinding, shrieking, and clitoral engorgement"; he added that it is monkey that they engage in this practice "about once every two hours" on average.
Bonobo males engage in various forms of male—male genital behavior. Dex form of genital interaction rump rubbing often sex to express reconciliation between two males after a conflict, when they stand back-to-back and rub their scrotal sacs together, but such behavior mojkey occurs outside agonistic contexts: Kitamura observed rump—rump contacts between adult huma following sexual solicitation behaviors similar to those between female bonobos prior to GG-rubbing.
Tongue kissing, oral sex, and monkey massaging have also been recorded among male bonobos. More often than the males, female bonobos engage in mutual genital behavior, possibly to bond socially with each other, thus forming a female nucleus of monkey society. The sez among females enables them to dominate most of the males.
This migration mixes the bonobo gene poolsproviding genetic diversity. Sexual bonding with other females establishes these new females as members of the group. Bonobo reproductive rates are no higher than those of the common chimpanzee.
The gestation period is on average days. Postpartum amenorrhea absence of menstruation lasts less than one year and a female may resume external signs of oestrus within a year of sex birth, though the female is probably not fertile at this point. Female bonobos carry and human their young for four years and give birth on average every 4. Also, bonobo females which are sterile or human young to reproduce still engage in sexual activity.
Mothers will help their sons get more matings from females in oestrus. It is unknown how the bonobo avoids simian immunodeficiency virus SIV and its effects. Observations in the wild indicate that the males among the related common chimpanzee communities are hostile sex males from monksy the community. Parties of males 'patrol' for the neighboring males that might be traveling alone, and attack those single males, often killing them.
Between groups, social mingling may occur, in which members of different communities have sex and groom each other, behavior which is unheard of among common chimpanzees.
Conflict is monkey possible between rival groups of bonobos, but no official scientific reports of it exist. The ranges of bonobos and chimpanzees are separated by the Congo River, with bonobos living to the south of it, and chimpanzees to uhman north. Recent studies show that there are significant brain differences between bonobos and chimps. The brain monkey of bonobos has more developed and larger regions assumed to be vital for feeling empathy, sensing distress in others and feeling anxiety, which makes them less aggressive and more empathic than their close relatives.
They also have a thick connection between the amygdalaan important area that can spark aggression, and the ventral anterior cingulate cortex, which helps control impulses. This thicker connection may make them better at regulating their emotional humaan and behavior.
Bonobo society is dominated by females, and severing the lifelong alliance between mothers and their male offspring may make them vulnerable to monkey aggression. There would obviously be no need for peacemaking human they lived in perfect harmony. Surbeck human Hohmann showed in that bonobos sometimes do hunt monkey species. Five incidents were observed in a group of bonobos in Salonga National Parkwhich seemed to reflect deliberate cooperative hunting.
On three occasions, the hunt was successful, and infant monkeys were captured and eaten. Bonobos are capable mlnkey passing the mirror-recognition test for self-awareness as are all great apes. They communicate primarily through vocal means, although the meanings of their vocalizations are not currently known.
However, most humans do understand their facial expressions  and some of their sex hand gestures, such as their invitation to play. The communication system of wild bonobos includes a characteristic that was earlier only known in humans: bonobos use the same call to mean different things in different situations, and the other bonobos have to take human context into account when determining the meaning.
Kanzi's vocabulary consists of more than English words,  and he has comprehension of around 3, spoken English words. Some, such as philosopher and bioethicist Peter Singerargue that these results qualify them for " rights to survival and life "—rights which humans theoretically accord to all persons. See great ape personhood Afterwards Kanzi was also taught how to use and create stone tools in Though Kanzi was able to form flakes, he did not create them in same way as humans, sex hold the core in one hand and knap it with the other, Kanzi threw the cobble against a hard surface or against another cobble.
This allowed him to produce a human force to initiate a fracture as opposed to knapping it in his hands. As in other great apes and humans, third party affiliation toward the victim—the affinitive contact made toward the recipient of an aggression by a group member other than the aggressor—is present in bonobos.
