3. Chagnon vs. Harris Causes of Yanomamo Warfare Chagnon:--Fighting over Women --”We like meat, but we like women better.” Harris:--Protein Scarcity --Mechanism of Population Control --Male Supremacy Complex --female infanticide

(Warfare, therefore, not explained.) --proximate explanation -- emic explanation Harris:--Protein Scarcity vs. Protein Deficiency (Big Mac) --Yanomamo Shamatari population increase -- from 200 to 2,000 people, 1900 - 1970

Than the Dobe Ju/’hoansi 4.Reliance on insects for food. (cost/benefit) 5.Evidence of recent adaptation a. Boil bananas only b. Fish only with poison c. Poorly constructed canoes
