In all, the scientists collected data on 18 chimpanzee groups and four bonobo groups living in Africa. Heart disease is common in humans and chimpanzees, but is - PubMed "We believe that human-nonhuman primate interaction is going to be among the most important areas of primatological research in the 21st century," concluded Hockings. Osvath said, "What is interesting is that he made these preparations when the visitors were out of sight, and also that he incorporated innovations into the behavior. The finely tuned motor system in humans gives us the ability to do things like make complex tools, throw accurately and manipulate small objects.
