Formerly the bonobo was known as the "pygmy chimpanzee", despite the bonobo having a similar body size to the common chimpanzee. The name "pygmy" was given by the German zoologist Ernst Schwarz in 1929, who classified the species on the basis of a previously mislabeled bonobo cranium, noting its diminutive size compared to chimpanzee skulls.
Bonobos frequently have sex, sometimes to help prevent and resolve conflicts. Different groups of chimpanzees also have different cultural behaviour with preferences for types of tools. [53] The common chimpanzee tends to display greater aggression than does the bonobo. [54] The average captive chimpanzee sleeps 9 hours and 42 minutes per day. [55]
Chimpanzee hand (left) compared to human hand. Chimpanzee bodies are covered by coarse hair, except for the face, fingers, toes, palms of the hands, and soles of the feet. Chimpanzees lose more hair as they age and develop bald spots. The hair of a chimpanzee is typically black but can be brown or ginger.
Chimpanzees, and the closely related bonobos, are the species nearest genetically to humans, sharing about 98.8% of our DNA. ... land use in their range will result in different effects on ...
According to Meinelt, it was an intentional decision by zoo officials to bring in bonobos rather than chimpanzees, recognizing the need to raise awareness about the lesser-known species and to ...
Her bonobo research examines why bonobos have evolved a very different social system compared to the closely related chimpanzee. She graduated from Cambridge University, UK, with a BA in 1980, an MA in 1984, and a PhD from Stony Brook University , Department of Ecology and Evolution, New York in 1986.
Bonobos (Pan paniscus) are social animals that live in less hierarchical structures than chimpanzees. Hare, Melis, Woods, Hastings, and Wrangham set out to compare cooperation in chimpanzees and bonobos. They first ran a cofeeding experiment for each species. Pairs of bonobos were given two food dishes.
This may be due to difference in the rewards gained by tool use: Gombe chimpanzees collect 760 ants/min compared to 180 ants/min for the Tai chimpanzees. [25] Some chimpanzees use tools to hunt large bees (Xylocopa sp.) which make nests in dead branches on the ground or in trees. To get to the grubs and the honey, the chimpanzee first tests for ...
