Underlying the anthropological study of man is the principle that there is a reality to which man must adapt if he is to survive, reproduce, and to perpetuate himself. Populations must adapt to the realities of the physical world and maintain a proper fit between their biological makeup and the pressures of the various niches of the world in which they seek to live. Social groups - where culture is found - must de velop adaptative mechanisms in the organization of their social relations if there is to be order, regularity, and predictability in patterns of cooperation and competition and if they are to survive as viable units. This three-volume set of readings presents an introduction to anthropology that is unified and made systematic by focus on adaptations that have accompanied the evolution of man, from non-human primate to inhabitant of vast urban areas in modern industrial societies. Man in Adaptation: The Biosocial Background serves as an introduction to Physical Anthropology, Linguistics, and Archeology from the point of view of processes of adaptation.It focuses on the role of biological adaptation in man's attempts to transcend the restrictions of his natural habitats and deals with the principle issues and concepts in the study of human evolution. These volumes are the first attempt to unify the disparate subject matter of anthro pology within a single and powerful explanatory framework. They incorporate the work of the most renowned anthropological experts on man, and they illuminate clearly one of the most important concepts around which one can build an investigation of the nature and scope of anthropology itself. For these reasons, they are recognized as indispensable reading for every professional anthropologist and as perhaps the best available means of introducing new students to the field.
