Society for American Archaeology The Evolution of Social Ranking on the Northwest Coast of North America

Abstract

The small, hierarchically organized societies on the Northwest Coast provide excellent examples of the evolution of social complexity in nonagricultural contexts and thus can serve as an important testing ground for current models. Available archaeological data indicate that ranking appeared on the coast between 3,000 and 2,000 years ago. It is argued here that ranking developed from the interaction of two systems constraints and two processes: subsistence specialization, environmental circumscription and population growth, and pro- motion. Ranking develops because, given certain conditions, it provides both improved monitoring of the en- vironment and improved responses to environmental shifts through information flow. Chiefdoms
