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.
Comparison of size of adult chimpanzee and adult human. The chimpanzee is tailless; its coat is dark; its face, fingers, palms of the hands, and soles of the feet are hairless. The exposed skin of the face, hands, and feet varies from pink to very dark in both species, but is generally lighter in younger individuals and darkens with maturity.
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.
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]
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.
The chimpanzees in the area have little fear of humans, because of a local legend, that humans and bonobos were cousins. "According to this belief, an older brother in a family of bonobos held to their traditional lifestyle and his descendants thus remained in the forest as bonobos. However, his younger brother was tired of eating raw foods.
In the wild, among males, bonobos are half as aggressive as chimpanzees, while female bonobos are more aggressive than female chimpanzees.Both bonobos and chimpanzees exhibit physical aggression more than 100 times as often as humans do.[121] To: "While bonobos are more peaceful than chimpanzees, it is not true that they are unaggressive.[121]
J. Fred Muggs (a chimpanzee born 1952) was a "co-host" with Dave Garroway on NBC's Today Show in the 1950s. Jiggs, a chimpanzee, was the first Cheeta in the Tarzan films in the 1930s. Jimmy, a chimpanzee, appeared in the film Dark Venture; Joe Martin, an orangutan, appeared in several silent-era American films
