Social and cultural anthropology, one of the four sub-disciplines of anthropology, covers a rich field from the simplest primitive society to the most complex industrial society. Individuals who wish to work in this field learn to describe social and cultural differences while studying people and culture. By considering the similarities and differences among people, it studies people with a comparative perspective. The program of the department is designed to include courses and practices related to social anthropology, cultural anthropology, the historical development of anthropology, anthropological theories and theorists, anthropological research methods, and field studies. This discipline is distinguished from others by the importance it places on field studies. Why do people and societies change and how do they change? Why are they similar or dissimilar?
