An anthropologist is a person engaged in the practice of anthropology. Anthropology is the study of various aspects of humans within past and present societies. 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.
Anthropologists usually cover a breadth of topics within anthropology in their undergraduate education, and then proceed to specialize in topics of their own choice at the graduate level. In some universities, a qualifying exam serves to test both the breadth and depth of a student's understanding of anthropology; the students who pass are permitted to work on a doctoral dissertation.
