“The evidence strongly suggests that small-scale warfare is part of our evolutionary history predating agriculture and sedentism, but that cooperation across group boundaries is also part our evolutionary legacy. . . . our evolutionary history is more complex than one of selection for war or peace; rather, it reflects the complicated lifeways of a highly social and interdependent cultural species for which both cooperation and war were likely important selective forces.”
