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.
Chimpanzee and bonobo: comparison The chimpanzee ( P. troglodytes ), which lives north of the Congo River , and the bonobo ( P. paniscus ), which lives south of it, were once considered to be the same species, but since 1928 they have been recognized as distinct. [ 6 ]
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]
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.
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.
In the past, bonobos were incorrectly relegated to subspecies status within the species chimpanzee. It is now understood that bonobos are an entirely different species. After Pan paniscus was differentiated and named as a new species to science, "bonobo" developed into its accepted common name. As bonobos aren't chimpanzees, old common names ...
