Horgan also makes an even more powerful argument against the idea that this study means much about human behaviour: Among bonobos (Pan paniscus, also called pygmy chimpanzees), a species that is less common than the Pan trogodytes (commonly just called chimpanzees) on the other side of the Congo River that the study focuses on, any kind of violence is rare and inter-communal killings all but unknown. (Wilson et aal. examined four bonobo communities and found only one "suspected" killing.) In fact, bonobo behaviour and their social structures are very different than chimps in many ways. For instance, unlike chimps, males are not dominant among bonobos. Since bonobos are as genetically close to modern human beings as chimpanzees, this is a strong counter-argument to the claim that the common ancestors of people and chimps passed on genes for violent behaviour.
What best describes and accounts for the spectacular success of our species is the degree to which human behaviour is not biologically programmed – human beings' ability to change as they change their world. As Karl Marx wrote, "All history is nothing but the continuous transformation of human nature." In a book advancing this understanding, Ardea Skybreak wrote, "Luckily for those of us who don't particularly like the present order of things, all of history points to the prevailing social relations rather than innate constraints in our biological makeup as the key factor mediating every aspect of human social life at different points in history and in different parts of the globe."
There is evidence, including recent archaeological findings, that while there was violence within and especially between communities, war was unknown among modern human beings for more than 100,000 years. Roughly 13,00 years ago, the development of agriculture, raising animals and other developments in the way people produced what they needed to live and made it possible for the emergence of private property and the division of society of into classes. Ever since that time, the dominate ideas in societies have been those corresponding to the interests and outlook of the ruling classes.
As Skybreak says, "How ironic and revealing, then, that just as we finally attain a level where a material basis exists for doing away with oppression and exploitation on a global scale, there are long lines of apologists in the sciences and the media who are bending over backwards to find some kind – any kind – of proof for the notion that there are some unchanging innate characteristics of human nature which would make this leap impossible."
The unjustified conclusions drawn from the Nature paper are an example of "confirmation bias", a kind of circular reasoning where, consciously or unconsciously, people choose to honour some alleged evidence and discard other evidence and arguments because they consider truth to be determined by whatever they have already concluded – or by the prevailing ideas in society, in this case that violence and even war are embedded in human beings' genetic make-up.
The outstanding multi-disciplinary scientist Stephen Jay Gould once described such conclusions about "human nature" as "unsupported speculations with political clout." There is no scientific evidence for the existence of the kind of unchanging and unchangeable "essence" that is meant by the term "human nature".
As the blogger Horgan reminds readers, this conception of inherently violent "human nature" is popular not only among scientists accorded high status, such as Edward O. Wilson and Stephen Pinker, it is also favoured by U.S. political leaders from the Bush administration to Obama. "Barack Obama was alluding to the theory when he said in 2009, while accepting the Nobel Peace Prize, 'War, in one form or another, appeared with the first man," Horgan writes. In other words, even as he was accepting the peace prize, he was arguing that war is an inevitable and eternal consequence of human biology.
This idea is implicit in today's speeches of U.S., UK and French leaders about the situation in Syria and Iraq, which they ascribe to "barbarism" and "savages", as if people who reject the cruel and hypocritical "Western civilization" they represent were reverting to humanity's default state. Some reactionary commentators argue that this makes it wrong to look at the economic, social and political factors that gave rise to the also reactionary Islamist jihadis, such as the effects of their own wars of aggression and occupation and the global imperialist system that has thrived on the domination of whole nations by the monopoly capitalists based in a handful of powers.
To his credit, the paper author Wrangham told The New York Times, "I certainly wouldn't want to say that chimps have anything much to say directly about what's going on in Syria." (17 September 2014). But by arguing that chimpanzee behaviour indicates that human beings are programmed for war, as he repeats in this interview, that is the claim he is giving aid and comfort to with his own faulty conclusions.
Complex human behaviour is not genetically programmed, and still less social behaviour, such as war, on any scale. As has been seen once again in the West over the past few months, a "war mood" is made, not born. It is created when the political representatives of the ruling classes feel the need to go to war – it is the result and not the cause of political decisions.
