In the case of an adult victim, the attacking males take turns beating and jumping on the victim. 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. The team concluded that the conservation of primate habitat is crucial to preventing resource based attacks on humans by primates. Then in the summer of 2009, the Ngogo chimpanzees began to use the area where two-thirds of these events occurred, expanding their territory by 22 percent.

The Jane Goodall Institute UK noted that pet chimpanzees are destructive and too dangerous to be kept as part of the family, and that it is difficult to keep them stimulated and satisfied in a human environment.
