Anthropology is the study of humans and human behaviour and societies in the past and present. Social anthropology and cultural anthropology study the norms and values of societies. Linguistic anthropology studies how language affects social life. Biological or physical anthropology studies the biological development of humans.
Archaeology, which studies past human cultures through investigation of physical evidence, is thought of as a branch of anthropology in the United States, while in Europe, it is viewed as a discipline in its own right or grouped under other related disciplines, such as history.
