Primatologists from the University of Zurich say they have observed so-called “policing” among chimpanzee groups that provides the conflict resolution necessary to ensure there is peace and order among the primates.

They found that high-ranking males and females are almost always the most successful when it comes to intervening impartially as peacemakers.

Writing in the journal PLoS ONE, the researchers say they determined the behavior is entirely for conflict resolution and not for the direct benefit of the chimp or chimps doing the policing.

“The interest in community concern that is highly developed in us humans and forms the basis for our moral behavior is deeply rooted. It can also be observed in our closest relatives,” concludes researcher Rudolf von Rohr.
