Materialist, cultural and biological theories on why Yanomami make war

Abstract

For decades, there have been three primary anthropological perspectives on why people make war: materialist, cultural, and biological. Each has a long history of application to the Yanomami. This paper considers these three alternatives. First, it summarizes the author's materialist models and what they are purported to explain. Second, it discusses more cultural explanations offered by several field researchers, concluding that some might be synthesized with a materialist perspective, while others seem irreconcilable. Finally, a range of hypotheses invoking evolved predispositions are considered and found to be directly contradicted by Yanomami ethnography, even if limited to the works of Napoleon Chagnon.
