Cultural anthropology is a branch of anthropology focused on the study of cultural variation among humans. Cultural anthropologists systematically explore topics such as technology and material culture, social organization, economies, political and legal systems, language, ideologies and religions, health and illness, and social change. Cultural anthropology is the study of human ways of life in the broadest possible comparative perspective. The book presents anthropology as a set of tools for both research strategies and a set of practical ideas that help us better understand and engage the world around us. The aim of cultural anthropology is to document the full range of human cultural adaptations and achievements and to discern in this great diversity the underlying covariations among and changes in human ecology, institutions and ideologies.
