Bonobos help strangers without being asked

A passer-by drops something and you spring to pick it up. Or maybe you hold the door for someone behind you. Such acts of kindness to strangers were long thought to be unique to humans, but recent research on bonobos suggests ...

Peter Gabriel wants to talk with animals online

Peter Gabriel joined big thinkers and one of the Internet's founding fathers Friday in launching an "Interspecies Internet" for animals to communicate with us and each other.

Peaceful bonobos may have something to teach humans

Humans share 98.7 percent of our DNA with chimpanzees, but we share one important similarity with one species of chimp, the common chimpanzee, that we don't share with the other, the bonobo. That similarity is violence. While ...

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 ...

Dutch experiment with 'Tinder for orangutans'

An animal reserve in the Netherlands is having apes respond to images of their fellow creatures on a tablet, a programme dubbed "Tinder for orangutans" by the Dutch press.

In fathering, peace-loving bonobos don't spread the love

Bonobos have a reputation for being the peaceful, free-loving hippies of the primate world. But, researchers reporting in Current Biology on July 10 have discovered that despite friendly relations between the sexes, particular ...

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.
