"Some apes throw sticks or feces, but Santino doesn't have access to any good-sized sticks, and he really dislikes putting his fingers on gooey stuff, including feces.". She also reports on general science, including archaeology and paleontology. Wiley. Attackers use their canines to bite and tear at the victim, so that any body parts that stick out, such as testes and ears, are often ripped off during an attack.. Chimpanzees (along with bonobos) are humans' closest living relatives. Empathy, deception (as for Santino) and other qualities usually only reserved for humans can be linked to this process. "Humans have long exploited nonhuman primates, our closest living relatives, for food, traditional medicine and even as pets. "They had been on patrol outside of their territory for more than two hours when they surprised a small group of females from the community to the northwest," Amsler said. But some anthropologists have resisted this interpretation, insisting instead that today's chimps are aggressive only because they are endangered by human impact on their natural environment. "Our observations help to resolve long-standing questions about the function of lethal intergroup aggression in chimpanzees.". The team investigated eleven attacks, carrying out victim interviews and found that although the families of attack victims felt angry and fearful toward chimpanzees after attacks, some drew on their traditional beliefs to explain why chimpanzees were respected, protected, and could not hurt them, even when attacks occurred.

In fact, male chimpanzees are often known to attack one another over territorial disputes. "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. The research on nonhuman primate attacks is an example of how human ecology and behaviour can influence, and be influenced by, the ecology and behaviour of primates.

Their diet includes insects and mammals, such as monkeys and bushbuck antelope, according to the Jane Goodall Institute UK. "I am surprised that [the study] was accepted for publication," says Robert Sussman, an anthropologist at Washington University in St. Louis, who questions the criteria the team used to distinguish between the two hypotheses. Indeed, it's important to be smart while hiking in regions where large predators live. Chimpanzees typically direct their aggressive and sometimes predatory behavior toward children because the animals are more fearful of larger human adults, especially men, according to National.
