Have humans always fought and killed each other, or did they peacefully coexist until states developed? Is war an expression of human nature or an artifact of civilization? Questions about the origin and inherent motivations of warfare have long engaged philosophers, ethicists, anthropologists as they speculate on the nature of human existence. In How War Began, author Keith F. Otterbein draws on primate behavior research, archaeological research, data gathered from the Human Relations Area Files and a career spent in research and reflection on war to argue for two separate origins. He identifies two types of military organization: one which developed two million years ago at the dawn of humankind, wherever groups of hunters met and a second which developed some 5,000 years ago, in four identifiable regions, when the first states arose and proceeded to embark upon military conquests. In carefully selected detail, Otterbein marshals the evidence for his case that warfare was possible and likely among early Homo sapiens. He argues from analogy with other primates, from Paleolithic rock art depicting wounded humans, and from rare skeletal remains with embedded weapon points to conclude that warfare existed and reached a peak in big game hunting societies. As the big game disappeared, so did warfare — only to reemerge once agricultural societies achieved a degree of political complexity that allowed the development of professional military organizations. Otterbein concludes his survey with an analysis of how despotism in both ancient and modern states spawns warfare.
