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]
The Hominidae (/ h ɒ ˈ m ɪ n ɪ d iː /), whose members are known as the great apes [note 1] or hominids (/ ˈ h ɒ m ɪ n ɪ d z /), are a taxonomic family of primates that includes eight extant species in four genera: Pongo (the Bornean, Sumatran and Tapanuli orangutan); Gorilla (the eastern and western gorilla); Pan (the chimpanzee and the bonobo); and Homo, of which only modern humans ...
This is a list of large extant primate species (excluding humans) that can be ordered by average weight or height range.There is no fixed definition of a large primate, it is typically assessed empirically. [1]
Extant primates exhibit a broad range of variation in sexual size dimorphism (SSD), or sexual divergence in body size. [4] It ranges from species such as gibbons and strepsirrhines (including Madagascar's lemurs) in which males and females have almost the same body sizes to species such as chimpanzees and bonobos in which males' body sizes are larger than females' body sizes.
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.
One study analyzed sounds made by human babies and bonobos when tickled. It found that although the bonobo's laugh was a higher frequency, the laugh followed the same sonographic pattern as human babies and included similar facial expressions. Humans and chimpanzees share similar ticklish areas of the body such as the armpits and belly. [6]
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.
