Chimpanzees have policemen, too

http://cdn.physorg.com/newman/gfx/news/2012/chimpanzeesh.jpgConflict management is crucial for social group cohesion, and while humans may still be working out some of the details, new research shows that some chimpanzees engage in impartial, third-party “policing” activity as well.Conflicts are inevitable wherever there is cohabitation. This is no different with our closest relatives, the chimpanzees. Sound conflict management is crucial for group cohesion. Individuals in chimpanzee communities also ensure that there is peace and order in their group. This form of conflict management is called “policing” – the impartial intervention of a third party in a conflict. Until now, this morally motivated behavior in chimpanzees was only ever documented anecdotally. However, primatologists from the University of Zurich can now confirm that chimpanzees intervene impartially in a conflict to guarantee the stability of their group. They therefore exhibit prosocial behavior based on an interest in community concern.

The willingness of the arbitrators to intervene impartially is greatest if several quarrelers are involved in a dispute as such conflicts particularly jeopardize group peace. The researchers observed and compared the behavior of four different captive chimpanzee groups. At Walter Zoo in Gossau, they encountered special circumstances: “We were lucky enough to be able to observe a group of chimpanzees into which new females had recently been introduced and in which the ranking of the males was also being redefined. The stability of the group began to waver. This also occurs in the wild,” explains Claudia Rudolf von Rohr, the lead author of the study.

Not every chimpanzee makes a suitable arbitrator. It is primarily high-ranking males or females or animals that are highly respected in the group that intervene in a conflict. Otherwise, the arbitrators are unable to end the conflict successfully. As with humans, there are also authorities among chimpanzees. “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 Rudolf von Rohr. …

    There’s another way looking at this. Instead of saying champanzees have policemen too, one could say humans haven’t evolved much above their nearest cousins, forest-dwelling chimps, because humans apparently still need “police” around, telling them what not to do. What places humans above chimps, it seems, is their technology, … Yet considering the recent technological catastrophies (as well as the ongoing and relentless technological assault on the environment) which all living species must contend, one might wonder if that is saying much, evolutionarily speaking. The human genotype is … what? … something like 98% similar to those of champanzees.
