Read an interesting book this morning on the anthropological research in to the basis of warfare.
One of the interesting points it makes is that anthropology rarely studies warfare as an anthropological or social activity. Rather, it studies the tools of warfare, and confuses those with the violence of warfare itself.
It put me in mind of this whole "people don't kill people, guns kill people" argument, and made me think that just maybe they're trying to solve the wrong problem...
