This is the first text to thoroughly cover nongenetic strategies of human adaptation to a variety of ecosystems. Designed to help students understand the multiple levels at which human populations respond to their surroundings, it is the most complete discussion of environmental, physiological, behavioral, and cultural adaptive strategies available. Among the unique features that make Human Adaptability outstanding as both a textbook and a reference are a complete discussion of the development of ecological anthropology and of relevant research methods; the use of an ecosystem approach with emphasis on arctic, high altitude, arid land, grassland, and tropical rain forest environments; the most extensive bibliography on ecological anthropology published to date, with over 700 references both classic and recent; and a comprehensive glossary of technical terms. In this updated edition, the author also addresses the impact of political economy, global environment change, demography, and health in the study of human ecology.
