Native to sub-Saharan Africa, chimpanzees and bonobos are currently both found in the Congo jungle, while only the chimpanzee is also found further north in West Africa. Both species are listed as endangered on the IUCN Red List of Threatened Species , and in 2017 the Convention on Migratory Species selected the chimpanzee for special protection.
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.
The same set-up was then used for pairs of chimpanzees. When both dishes had food, there was no difference in behavior between bonobos and chimpanzees. But when only one dish contained food, bonobos were more than twice as likely to share food than chimpanzees. Bonobos were more tolerant of each other than chimpanzees. [67]
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.

The split between the common ancestors of the chimpanzee and bonobos then took place about 1.5 to 2 million years ago with the two lineages giving rise to the two current extant species. In the past, bonobos were incorrectly relegated to subspecies status within the species chimpanzee. It is now understood that bonobos are an entirely different ...

Biologists classify humans, along with only a few other species, as great apes (species in the family Hominidae).The living Hominidae include two distinct species of chimpanzee (the bonobo, Pan paniscus, and the chimpanzee, Pan troglodytes), two species of gorilla (the western gorilla, Gorilla gorilla, and the eastern gorilla, Gorilla graueri), and two species of orangutan (the Bornean ...
