An anthropologist is a person with an extensive knowledge of anthropology who uses this knowledge in their work, typically to solve problems specific to humanity. Anthropology is concerned with studying the subject matter of fields such as philosophical anthropology, archaeological anthropology, sociocultural anthropology, linguistic anthropology, literary anthropology, as well as biological anthropology and forensic anthropology. There is a sense in which every human being is an anthropologist, if a very humanistic and generous interpretation is accepted. This is to say that every human being is related to others and has a unique way of life. However, a more generally accepted interpretation in academia is that an anthropologist is one who has attained a Ph.D. in anthropology, teaches anthropology or carries out anthropological field research, and has published literature in a field of anthropology in a peer-reviewed journal, or is widely accepted by other anthropologists as an anthropologist.
