Anthropology is a multidimensional study of humankind, integrating cultural, sociological, historical, and evolutionary perspectives of human diversity within a single discipline. Crossing boundaries that have often separated the humanities and sciences, anthropology examines both the organic evolution of our biological family and the variety and unity of peoples, societies, and cultures worldwide and across millennia. The shared goal of anthropology's various subfields is to contribute to a global picture of the human experience and, accordingly, Dartmouth's Department of Anthropology offers a four-field program of study in archaeology, biological anthropology, cultural anthropology, and linguistic anthropology.
