"The apes nest on the ground like gorillas, but they have a diet and features characteristic of chimpanzees", according to a "National Geographic" report. While preliminary genetic testing with non-nuclear DNA indicates a close relationship with the eastern chimpanzee ("Pan troglodytes schweinfurthii") subspecies of the common chimpanzee, a range of behaviors that are more closely related to those of gorillas have greatly intrigued primatologists from around the globe. Though their taxonomic classification has been clarified, the need for further information about these chimpanzees persists.
