Bonobo diet of aquatic greens may hold clues to human evolution

Observations of bonobos in the Congo basin foraging in swamps for aquatic herbs rich in iodine, a critical nutrient for brain development and higher cognitive abilities, may explain how the nutritional needs of prehistoric ...

Bonobo moms play an active role in helping their sons find a mate

Many social animals share child-rearing duties, but research publishing May 20 in the journal Current Biology finds that bonobo moms go the extra step and actually take action to ensure their sons will become fathers. From ...

Bonobos and chimps equally love meat

In an African forest where leopards and poisonous mamba dwell, a University of Oregon team once had to flee charging boar. But it was a brief detour in research that adds to the idea that bonobos are neither hippies nor vegans.

Bonobo: great ape with a tiny voice

Although bonobos and chimpanzees are similar in size, bonobo calls sound an octave higher than chimpanzee calls. Researchers at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, explain this discrepancy ...

Bonobos have human-like sense of disgust, researchers find

Even bonobos lose their appetites with enough if they experience disgust. These primates, known for their liberal attitudes toward sex, are also generally open-minded when it comes to new foods—as long as it's is clean.

Bonobos share and share alike

Bonobos are willing to share meat with animals outside their own family groups. This behaviour was observed in the Democratic Republic of the Congo and is documented in a new study in Springer's journal Human Nature. Even ...

Bonobo and chimpanzee gestures share many meanings

If a bonobo and a chimpanzee were to meet face to face, they could probably understand each other's gestures. In an article publishing 27 February in the open access journal PLOS Biology, researchers from the Universities ...

Bonobo

The bonobo (English pronunciation: /bəˈnoʊboʊ/ /ˈbɒnəboʊ/), Pan paniscus, previously called the pygmy chimpanzee and less often, the dwarf or gracile chimpanzee, is a great ape and one of the two species making up the genus Pan. The other species in genus Pan is Pan troglodytes, or the common chimpanzee. Although the name "chimpanzee" is sometimes used to refer to both species together, it is usually understood as referring to the common chimpanzee, while Pan paniscus is usually referred to as the bonobo.

The lifespan of a bonobo in captivity is about 40 years. The lifespan in the wild is unknown.

Bonobos are far less aggressive than chimpanzees and other apes.

The bonobo is endangered and is found in the wild only in the Democratic Republic of the Congo. Along with the common chimpanzee, the bonobo is the closest extant relative to humans. Because the two species are not proficient swimmers, it is possible that the formation of the Congo River 1.5–2 million years ago led to the speciation of the bonobo. They live south of the river, and thereby were separated from the ancestors of the common chimpanzee, which live north of the river.

German anatomist Ernst Schwarz is credited with having discovered the bonobo in 1928, based on his analysis of a skull in the Tervuren museum in Belgium that previously had been thought to have belonged to a juvenile chimpanzee. Schwarz published his findings in 1929. In 1933, American anatomist Harold Coolidge offered a more detailed description of the bonobo, and elevated it to species status. The American psychologist and primatologist Robert Yerkes was also one of the first scientists to notice major differences between bonobos and chimpanzees. These were first discussed in detail in a study by Eduard Paul Tratz and Heinz Heck published in the early 1950s.

The species is distinguished by relatively long legs, pink lips, dark face and tail-tuft through adulthood, and parted long hair on its head.

Bonobos are perceived to be matriarchal: females tend to collectively dominate males by forming alliances; females use their sexuality to control males; a male's rank in the social hierarchy is determined by his mother's rank. However, there are also claims of a special role for the alpha male in group movement.[citation needed] The limited research on Bonobos in the wild was also taken to indicate that these matriarchal behaviors may be exaggerated by captivity, as well as by food provisioning by researchers in the field. This view has recently been challenged, however, by Duke University's Vanessa Woods; Woods noted in a radio interview that she had observed bonobos in a spacious forested sanctuary in the DRC exhibiting the same sort of hypersexuality under these more naturalistic conditions; and, while she acknowledges a hierarchy among males, including an "alpha male", these males are less dominant than the dominant female.
