Something is missing in our swirling national debate about gun control: an appreciation of our species' 500,000-year affinity for weapons.
I have never owned a gun or lived in a household with one. The only time I can remember pulling a trigger is a few .22 shots at a YMCA camp in about 1959. My rational faculties shout that it's crazy for us to allow the widespread circulation of marginally useful implements being used regularly to murder children.
But loudly announcing my rational views will change the mind of precisely ... no one. The prominent social psychologist Jonathan Haidt has taught us that where political values are involved, our rational faculties are like a rider trying to control an elephant. Political progress requires gaining the perspective to see the elephants of instinct and deep-seated sentiments that all of us are riding.
We can start seeing the elephant of gun ownership by looking at a peculiar historical development that has puzzled evolutionary scientists. Our closest evolutionary cousins, chimpanzees and gorillas, typically live in hierarchical bands dominated by an alpha male with perhaps a couple of allies. But the human hunter-gathers that evolved from the same ancestor as the apes almost invariably lived in egalitarian groups with no hierarchy and where resources were shared. What happened?
Anthropologist Christopher Boehm, head of the Goodall Research Center and who worked with her at Gombe, has proposed a persuasive explanation. The combination of language and weapons made it possible for a coalition of rebellious subordinates to depose any bully who attempted to dominate the band. A cave painting in Spain from some 10,000 years ago depicts 10 figures with bows and a body on the ground with 10 arrows in it.
Weapons have been such a long-standing and important feature of our evolution that they have probably contributed to physical changes — shrinkage of the canine teeth used in weaponless combat, loss of the body hair that bristles in displays of prowess, and reduction in the size difference between males and females.
It is likely, then, that we are the descendants of people who successfully used weapons to preserve their autonomy and achieve a measure of equality. After the 20,000 generations of genetic shuffling since weapons first appeared, we are likely to have developed some pretty strong instincts about the importance of being armed.
Recognition of this evolutionary past can contribute two insights to the debate about gun control. First, guns won't go away quietly, at least not in a culture with America's frontier history.
