== 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.<ref name="Shefferly2005">{{cite web |url= http://animaldiversity.ummz.umich.edu/site/accounts/information/Pan_troglodytes.html |title=''Pan troglodytes'' |access-date=August 11, 2007 |work= Animal Diversity Web |publisher=University of Michigan Museum of Zoology |author= Shefferly, N. |year=2005}}</ref> In addition, ''P. troglodytes'' is divided into four [[subspecies]], while ''P. paniscus'' is undivided<!--By definition, it is not possible for a species to have a single subspecies, it either has 2 or more subspecies or none-->. Based on [[genome sequencing]], these two extant ''Pan'' species diverged around one million years ago.

The most obvious differences are that chimpanzees are somewhat larger, more aggressive and male-dominated, while the bonobos are more gracile, peaceful, and female-dominated. Their hair is typically black or brown. Males and females differ in size and appearance. Both chimpanzees and bonobos are some of the most social great apes, with social bonds occurring throughout large communities. Fruit is the most important component of a chimpanzee's diet; but they will also eat vegetation, bark, honey, insects and even other chimpanzees or monkeys. They can live over 30 years in both the wild and captivity.

Chimpanzees and bonobos are equally humanity's closest living relatives. They use a variety of sophisticated tools and construct elaborate sleeping nests each night from branches and foliage. Their learning abilities have been extensively studied. There may even be distinctive cultures within populations. Field studies of ''Pan troglodytes'' were pioneered by primatologist [[Jane Goodall]].
