How biology explains war.

22 11 2008

Malcom Potts and Thomas Hayden have wirtten a book called ‘Sex and War’, it seems to present an interesting exploration into the evolution of humatiy’s violent tendencies for war. They also cover the issue of how population growth, resource use and violence intersect. This point relates well to my previous post on military expenditure and ecological footprints. I would like not to think of a barbarized future in which millions of people try to migrate to northern latitudes.sexandwar_5inch_bright_op_400_600

“Today’s most brutal wars are also the most primal. They are fought with machetes in West Africa, with fire and rape and fear in Darfur, and with suicide bombs and improvised explosive devices in Israel, Iraq, and elsewhere. But as horrifying as these conflicts are, they are not the greatest threat to our survival as a species. We humans are a frightening animal. Throughout our species’s existence, we have used each new technology we have developed to boost the destructive power of our ancient predisposition for killing members of our own species. From hands and teeth tearing at isolated individuals, to coordinated raids with clubs and bows and arrows, to pitched battles, prolonged sieges, and on into the age of firearms, the impulse has remained the same but as the efficiency of our weapons has increased, the consequences have grown ever more extreme…The evidence of history is that no advance which can be applied to the killing of other human beings goes unused. As scientific knowledge continues to explode, it would be naïve, to expect any different. As if we needed any more reasons to confront the role of warfare in our lives, the present supply and future potential of WMDs should convince us that the time has come once and for all to bring our long, violent history of warring against each other to an end.”

“…all team aggression, all raiding, and all wars are ultimately about resources, even if the combatants aren’t consciously aware of it. All life, in fact, at its most fundamental level is about competition for resources. Evolution has been driven by this competition for billions of years, and today’s animals, plants, bacteria, protozoa, and fungi all exist because they competed successfully with their rivals in the past. If we are to have any chance of avoiding the wars of tomorrow, as the destructive power of today’s weapons tells us we must, then we have to address this most basic of biological problems: The fact that as the population of any species grows, the pressure on its natural resources increases and competition becomes more severe…Biology has invented a million ways for plants and animals to compete with each other. A tree may compete for light by growing taller; early mammals competed with dinosaurs by only coming out at night; humans and chimpanzees—especially the males—compete for food, space, and reproductive opportunities by fighting with each other. Human wars may come wrapped in a veneer of religion or political philosophy, but the battle for resources is usually just below the surface…In World War II, the need for land and resources was expressed as Hitler’s concept of lebensraum, or “living space.” “The aim [of] the efforts and sacrifices of the German people in this war,” he wrote, “must be to win territory in the East for the German people.” The Japanese attacked Pearl Harbor because they knew they had to destroy the American Pacific fleet if they were to access the Indonesian oil they needed to supply their industries.”

“The population of Rwanda was two million people in 1950, and on average each woman had almost 8 children. By 1994, average family size had fallen slightly to 6.2, but the population had quadrupled to almost eight million, resulting in a population density of 292 people per square kilometer, the highest in all of Africa. James Fairhead, an anthropologist from the School of Oriental and African Studies in London, adds an economic dimension to the analysis. Preceding the Rwanda genocide, Fairhead points out, agricultural land prices had reached an astronomical $4,000 per hectare in a country where many people lived on less than $500 a year. “Land,” Fairhead concludes, “is worth fighting for and defending.” Tragically, the fighting which took place in 1994 left between 500,000 and one million dead. It was cast as an ethnic conflict, and senseless. Once its roots in resource competition are laid bare, however, the violent extermination of an identifiable outgroup takes on the all-too familiar logic of team aggression.”

“For billions of years, evolution has been driven by competition caused by the simple fact that, left unchecked, all living things can reproduce faster than their environment can sustain. Our population growth today is largely unchecked by hunger, disease, or predators, and it is highly likely that our numbers and industrial demands have already exceeded the environment’s capacity to support them. Mathias Wackernagel in California, Norman Myers in England, and others calculate that we may have exceeded Earth’s carrying capacity as long ago as 1975. According to these calculations, we already need a planet 20 percent larger than the one we have. Such estimates are difficult to make and open to criticism. But it doesn’t take much more than an open set of eyes to realize that current human population growth and economic expansion are going to be impossible to sustain in the long term. competition for resources is about to increase markedly.”
