Anthropology from the Greek anthropos ( human ) and logia ( science ) is the scientific study of humankind, from its beginnings millions of years ago to the present day. Its subject matter is both exotic (initiation rites of the Ganda of Uganda) and commonplace (anatomy of the human hand). Its focus is both sweeping and microscopic. Anthropologists may study the environmental impact of a new industry, the folklore of West Virginia, primate disease patterns, prehistoric cultures in North Carolina, or secret societies. A common thread links these vastly different projects. The common goal is to advance knowledge of who we are and how we came to be that way.
