Conflict Resolution in Non-Human Apes

Conflict Resolution in Non-Human Apes

Where does violence come from? How violent are we? Are we becoming more or less violent with time? Is violence innate or something learned? How do we deter violence?

The topic of violence has enthralled humans apparently since our inception. I've recently been reading a book on the topic of violence, The Better Angels of Our Nature by Steven Pinker. It is a fascinating book, and made me want to shed some of my own thoughts on the topic. This is such a massive subject that I'm sure I would need to do at least a dozen takes on the subject just for us all to have a passing understanding of the subject. I may do that in time, but for today we'll just stick with one. I pondered where to start on this subject. One of the first questions that we need to address is where violence comes from. Is it something that we picked up from our ancestors, or is it unique to us? For this myTake I wanted to talk about conflict resolution among two of our closest extant cousins, chimpanzees and bonobos. We share approximately 98% of our DNA with both species, and I won't bother trying to teach evolution here. If you don't accept the science of evolution... Just read for interest of their behavior anyway.

Conflict Resolution in Non-Human Apes

Chimpanzees

Lethal Aggression in Pan Is Better Explained by Adaptive Strategies Than Human Impacts by Michael L. Wilson, Christophe Boesch, Barbara Fruth (many more authors! All credit to them, I just have a limited space to work with.) Is one of the most comprehensive studies on the subject of violence in the species Pan. Pan refers to both pan troglodytes and pan paniscus, or Chimpanzee and Bonobo respectively. Frequently people think that chimpanzees resort to violence as a result of human interaction, deforestation and the like, but in this study it was quite conclusively determined that human interaction has very little impact on aggression in chimp males. Actually, it appears that chimps mostly attack other chimp groups to gain land. This is highly reminiscent of violence in human hunter-gatherer groups prior to centration of government. The authors noted lethal violence in 15 of 18 chimpanzee communities. Males made up over 90% of the attacking parties, and when they attacked another chimp they outnumbered their victims 8:1. This is starkly contrasted with human violence only in that it appears we are likely to take greater risks.

Bonobos

The same study noted above also studied violence amongst our other close cousins. The Bonobos greatly differ from the Chimpanzees in that they rarely conduct violence, in fact the researchers had only noted one possible killing in a Bonobo community, and that was only suspected. Frans De Waal further explains that after 100s of hours of observation that he discovered Bonobos use sexual contact as a means of conflict resolution. If a fight is about to break out amongst two Bonobos they will just have sex instead. This happens quite frequently over fights about food, but has been noted between contests over females, over the striking of another Bonobo's child, and general annoyance. It's incredibly interesting to study Bonobo sex because they are so unique. Males and females appear to be equal in their communities, they have front facing sex, kiss profusely, have hetero and homo sex, will have sex between the young and old etc.

What does this mean for us?

Well, I'm not entirely sure. These two cousins have greatly differing means of conflict resolution, and yet both are incredibly closely related to us. I think that studying these two species can grant us valuable insights into our own biological predispositions. In looking at humans throughout antiquity it seems to me that our behavior is much more concordant with Chimpanzees but many societies today seem to be moving more towards a Bonobo type of societal structure. Perhaps many of our ancestors were once quite similar to the Bonobo and they just died out?

Anyway let me know how I did, if there's anything I can improve upon I'd appreciate the information.
