Evolutionary explanations for war posit that coalitional aggression against external social groups resulted in higher fitness over the long duration of the Pleistocene. The essential challenge of these models is to account for the selection for such risky behavior given the potentially high costs to participants in attacks. This entry focuses on one influential hypothesis developed from this body of theory: that war is more likely with higher likelihood of success.
Introduction
The antiquity of warfare is a fundamental question for a wide variety of social science disciplines and an important factor in how conflict might be reduced in the future. Recent multidisciplinary research has provided abundant evidence that warfare has a long chronology, dating far back into the Pleistocene (Allen and Jones 2014; Bowles 2009; Gat 2017). While defensive warfare is readily understood as an adaptive behavior in...
