This text provides a thorough presentation of the principles and processes of anthropology, both physical and cultural, including ethnology, linguistics and prehistoric archaeology. By integrating research and ideas from several schools of thought, it reflects current scholarship. Features new to this edition include expanded material on objectivity and falsification in science, the replication of results in anthropology, discussion of the Piltdown hoax to illustrate scientific methodology in physical anthropology, the methodology of cross-cultural comparison, and cross-cultural differences in infant sleeping arrangements and the implication of these differences for child development.
