Health in Prehistoric Populations of the Santa Barbara Channel Islands

Abstract

Skeletal remains from the Santa Barbara Channel Islands, California were analyzed to evaluate the health consequences of an economic shift from a generalized maritime hunting-and-gathering adaptation to one focused increasingly on fishing. Changes in stature and in the frequency of inflammatory bone lesions suggest that health generally declined during this economic shift. This occurred despite an increase in the protein content of the diet. These data provide a basis for evaluating the significance of protein deficiency as a cause of the deterioration in health seen with the development of intensive agriculture.
