Anthropology's specialty, more than any other discipline, is the study of human diversity across time and space. The formal establishment of the anthropology program dates from 1953. From that time the department has grown steadily to encompass the major fields of anthropology with strengths in archaeology, behavioral ecology, Native American studies, and applied-development anthropology. It offers the BA and BS degrees at the undergraduate level and the MA at the graduate level. In addition, it offers a specialized masters program in Professional Archaeology and the Indigenous Peoples doctoral specialization in Geography.
