Fields of Anthropology. There are now four major fields of anthropology: biological anthropology, cultural anthropology, linguistic anthropology, and archaeology. Each focuses on a different set of research interests and generally uses different research techniques. The methods range from those commonly used by the social sciences and humanities to those of biology and geology. Biological anthropology and archaeology are generally the closest to the biological and physical sciences in methods and approach to learning about the human experience.
