Chimps Make War, Bonobos Make Love, and Humans?

Journalism about biology often tells us more about our cultural assumptions and prejudices than about the science itself. Nicholas Wade’s most recent article in the New York Times about chimpanzees is no exception. After introducing us to John Mitani, the main chimp researcher in his piece, Wade says
Most days the male chimps behave a lot like frat boys, making a lot of noise or beating each other up. But once every 10 to 14 days, they do something more adult and cooperative: they wage war.
When I read those sentences, my mouth dropped open. My definition of cooperation doesn’t encompass war. In fact, cooperation and conflict are opposites as far as I can tell. And if I were a “frat boy,” I would have some difficulties with Wade’s initial comparison. In fact, as an adult human, I have a problem with all the assumptions that undergird Wade’s article.
His first assumption is that chimps are like humans, like frat boys or soldiers in particular. Watching television specials on chimpanzees, I haven’t noticed a great resemblance between the way these animals behave and the pranks of fraternity boys or the activities of army platoons. And in fact, there’s a lot of controversy about whether aggressive chimpanzees are our closest relatives or their cousins, the peacefull bonobos.
His second assumption is that warfare necessitates cooperation, when, in fact, it’s usually a matter of hierarchy, commands, and coercion. The “grunts” do what they’re told, and until recently, they never had any choice about whether they’d enlist or not. Instead, they were conscripted.
And finally, Wade assumes that warfare is more “adult” than the “frat boy” behavior he describes. Whew! I’ve always believed that war was a failure of mature behavior, an inability to work things out as grown-ups are supposed to do.
Where do these assumptions come from? They’re a part of our patriarchally gendered construction of reality. It’s important within a patriarchal society like ours — where men are in power and define themselves in contrast to women and women define themselves in contrast to men — for people to believe that we’re more closely related to chimps than bonobos. Chimpanzees live in a competitive, male-dominated culture, while bonobo society is peaceful, and matriarchal. Bonobos also engage in considerable same-sex behavior, something anathema to the definition of a “real man” within patriarchy. As I titled this piece, chimps make war, while bonobos make love — a lot actually, with almost every other bonobo in their group. As the Bonobo Conservation Initiative states on their website:
Bonobos live in large groups where harmonious coexistence is the norm. While in many ways, males and females have “separate but equal” roles, females carry the highest rank, and the sons of ranking females are the leaders among males. Females form close bonds and alliances, which is another way they maintain their power among males, who are larger and stronger physically.
Looking at the assumption that the chimps are behaving in an “adult” fashion when making war, we can see that in a patriarchal culture, mature masculinity is supposed to be assertive, a short step away from aggression. In contrast, mature feminity is supposed to involve cooperation, nurutrance, and caring. Socially endorsed masculinity in our culture also involves risk taking. These understandings lead quite “naturally” to the belief that mature masculinity is violent and war-like. So the surprising thing about Wade’s article is that he defines the aggressive behavior of chimps as both cooperative — a feminine attribute — AND warlike — a masculine quality.
Of course, women are not the only people who cooperate. And clearly there’s teamwork during war. Without it, many men wouldn’t survive. But cooperation on a social level is something altogether different, an attitude that would ultimately make war unnecessary. So putting these two concepts together is jarring to say the least.
When it comes to Wade’s assumptions about warfare, he’s way off the mark. The development of warfare coincided with the development of the city state in the 4th millenium BCE. From what we can tell, until the beginnings of the city-state, all societies were communal. In these prehistoric societies, survival depended on mutual cooperation. Certainly violent conflict took place between these prehistoric groups. But it was based on voluntary participation. With the beginnings of hierarchy, slavery, and class structure – all outgrowths of the the city-state – warfare as we know it today began to evolve.
What bothers me most about Wade’s article is that in making parallels between male chimp behavior and the activities of human men, he normalizes war. In fact, Wade talks about how
The chimps’ waging of war is “adaptive” … meaning that natural selection has wired the behavior into chimps’ neural circuity because it promotes their survival….The chimps are just innately aggressive toward their neighbors…
War, in his way of thinking, is just a natural part of the chimp or human condition. It’s in our genes and in the genes of our closest animal relatives. This would be the logical outcome if you put together all these assumptions of competitive, patriarchal culture.
But patriarchy is just one of many social forms, and certainly not the one that best serves us, especially if we’re women. And I don’t think it serves men very well either, since it forces them into a straightjacket of competition, risk taking, aggression, and stand-alone independence. Wouldn’t we all be better off in a culture of true cooperation, with the ability to compromise rather than imposing our will on everybody else or having it imposed on us (in its extreme called warfare)? Coercion by violent means needs to make way for a future of generosity, tolerance, and interdependence. In other words, realizing that we’re all in this together.




It is not clear to me whether the author is objecting to the anthropomorphism of the scientist or the attribution of maturity to the chimpanzee side of the equation. I do believe that the patriarchy of the scientist is blatant and upsetting. For me the real question is: Is the chimpanzee behavior hardwired, i.e. genetic or is it social? Is the Bonobo behavior social? I will admit that my own bias is for the Bonobos. I believe cooperative behavior is morally superior to aggressive behavior. But from a Darwinian perspective, the argument could be made as Mitani does that aggressive breeds selection and selection improves the survival function of the “race”.
Mitani would probably also argue that the Chimps would kick the bonobos’ ass, proving their superiority!
Without a higher, transcendent moral perspective it is not possible to argue with Mitani. I think he is a moral cretin. This is a case where cultural infects science and makes it replicate culturally dominant values, i.e. patriarchy.
Thank you for this article.
Hi, Jim –
I’m glad you enjoyed my post, and I think you hit on exactly my difficulty in writing it. I tried to do too much in too little space. If I were to write it again, it would probably end up twice as long.
As I said in my introductory sentence, I was mainly objecting to the reproduction of the Nicholas Wade’s patriarchal prejudices translated into a supposedly “objective” science article. But, of course, this implies his anthropomorphizing to begin with (on the one side) and the attribution of “maturity” to war-making within a human context as translated into the article in terms of chimps (on the other side). Does that make any sense?
To answer your questions, I personally believe that the great apes all have their own “cultures,” i.e. socially learned ways of living. Their cultures can’t be as extensive as ours, because of our superior language abilities. But, for instance, when my sister Amy came back from studying the mountain gorillas in Rwanda, she described their interactional style as similar to a human commune, with some of the females enjoying each other and some putting up with an occasional bad apple. Chimp culture is much more top-down than that. And bonobos seem to be very fluid in their interactions. All of these animals are highly intelligent, have long childhoods in which they learn a lot from their parents and other elders, and I don’t see why we shouldn’t consider the sum total of all of that “culture” or social learning.
As to your Darwinian question — which seems to be about group-level selection — if you read the entire NY Times article (http://www.nytimes.com/2010/06/22/science/22chimp.html), you’ll find a short, interesting discussion of whether or not group-level selection could be effective in the case of chimps. Mitani believes it is, but “Many biologists are skeptical, saying it could be effective only cases where there is intense warfare between groups, a reduced rate of selection on individuals, and little interchange of genes between groups” — most of which doesn’t apply to chimps.
What is missing for me, both in the original article and in this critique, is evidence that anything other than instinct operates for either chimps or bonobos. For humans, the element of choice is critical. We make decisions based on experience (understood as having a comprehensive history, taught and cumulative) and on anticipation of future consequences that are symbolically measured.
I recall seeing a description of a chimp in captivity who set aside a pile of stones that could then be used to throw at passersby. That practice, where objects are classified as available for an imagined future, resembles human behavior. However, in this case, as the chimp was in captivity, it might well be explained as immitative of some observed behavior of the chimp’s keepers. Still, even the ability to immitate at that level gives evidence of the fluidity of what I distinguish as a difference between instinct and choice.
Some very interesting replies to your piece, some of which I agree with, and some that I don’t. The notion that genetic and behavioral links between humans and great apes are anthropomorphic is mostly self serving, as humans have choices regarding their collective behaviors, and clearly we have made the wrong ones; we also possess an advantage over both the bonobo and the chimp, in that we are capable of collective thought and discourse.
As Jim states, it could be argued that aggression breeds survival success, and that may be true in more base instinctual societies, but we, as humans, possess the capacity to transcend such limits. Our survival needs have long been satisfied. It is our resolution behaviors that need modification. And, to be clear, we have long since abandoned any true desire to be communally tribal; long abandoned any action that might benefit the whole of humanity. We do not live to assure the survival of the species. We live to assure individual survival.
I will continue to believe that the human species fell prey to a gigantic, evolutionary misstep. And I will continue to find that misstep in the following paraphrased quote
Chimps resolve sexual issues through power; bonobos resolve power issues through sex. Feel free to replace ‘sex’ with ‘love’ in the human context.
If Tikkun Olam is really about repairing the world, then perhaps it is time to realize that we, as a culture, continue on the chimp path, with the accompanying historical blindness, and actually possess the consciousness to decide to follow the bonobo’s lead.
Thanks for listening.
Hi Rex and Larry –
It took me a while to get hold of my sister Amy Vedder (she’s a busy woman) to answer your questions about whether chimps and bonobos have learned “social behavior”‘/”culture” of if they’re just instinctual. She reminded me of several articles I had already read that indicate pretty strongly that the great apes and even some of the smaller primates have a lot of learned behavior. Thirty or so years ago researchers were feeding a group of rhesus macaques on an island potatoes. One of the younger monkeys started to wash its potatoes in the salt water, and s/he taught some of the others how to do it. It caught on so that eventually the entire island’s population of macaques washed their potatoes, but the islands around them didn’t, clearly a “cultural” difference between these populations. There are also chimps that use smaller rocks that they pound on larger, flat rocks to crack open fruit and nuts, a trait they then have passed on to their children. And most recently, it’s been discovered that chimps in Congo/Brazzaville are not only using tools and teaching their young how to do this, but also modifying tools for specific functions — one kind of stick for “termite fishing” and another for hunting stinging ants. In fact, there’s a video on YouTube showing them doing this at http://www.youtube.com/watch?v=EaEDeRJKN0s.
I’m not quite as pessimistic as you are, Larry, about how humans have fallen “prey to a gigantic, evolutionary misstep” and abandoned our communal traits for pure individualism. It’s true that most Western nations are dominated by competitive individualism, but even in those countries there ais usually a large cohort of people who interact much more communally than the dominant culture — namely, women. Communal cultures — and these include most indigenous societies and many other non-Western cultures, plus women’s culture — have at least six significant values that can help us to change to a more caring society: cooperation, compromise (which in the US is a dirty word), tolerance, flexibility, and interdependence (which really encompasses the first five). I believe that if we start listening to women and feminist men more frequently, we will change. And I believe that we must change if we are to survive. Tikkun Olam is possible, but it will be hard work in the U.S., which is the most individualistic culture in the world. I just wrote an article for SageWoman about all of this, but unfortunately, it won’t be out until the winter.
Hi Larry –
I forgot to add the sixth communal value, namely generosity which could offset the greedy attitudes of many Americans these days
Years ago at the Washington DC zoo, I wanted to film a gorilla who was sitting on a hillside eating some of the grass there. He glanced up to see my camera and from that point would never let me have an opportunity to film him in a candid way. He made sure I could not see his face fully. I finally gave up and apologized and promised I would never do such a thing again. I just enjoy the local chimps and other simians at the local zoo. Talk about a come down! I never underestimate the intelligence of any species no matter the behavior.
