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 western chimpanzee or West African chimpanzee [1] (Pan troglodytes verus) is a Critically Endangered subspecies of the common chimpanzee. It inhabits western Africa, specifically Côte d'Ivoire , Guinea , Liberia , Mali , Senegal , Ghana , Guinea-Bissau , but has been extirpated in three countries: Benin , Burkina Faso , and Togo .
Duplications of small parts of chromosomes have been the major source of differences between human and chimpanzee genetic material; about 2.7% of the corresponding modern genomes represent differences, produced by gene duplications or deletions [failed verification], since humans and chimpanzees diverged from their common evolutionary ancestor.
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 ...
The only place you can find bonobos in the wild is The Republic of Congo, where there are estimated to be as few as 15,000 left. The Ape Initiative in Des Moines is the only bonobo research ...
Sumatran orangutan (Pongo abelli) Hominoidea is a superfamily of primates. Members of this superfamily are called hominoids or apes, and include gorillas, chimpanzees, orangutans, gibbons, bonobos, and humans. Hominoidea is one of the six major groups in the order Primates. The majority are found in forests in Southeastern Asia and Equatorial Africa, with the exception of humans, which have ...
A new study looked at how the behaviour of bonobos, chimpanzees, western lowland gorillas and olive baboons changed as people started to return to zoos. As visitors returned, bonobos and gorillas ...
