Final answer:
Forensic anthropology is not one of the main fields of general anthropology; the main fields are biological anthropology, archaeology, cultural anthropology, and linguistic anthropology.
Step-by-step explanation:
The subdiscipline that is not one of the main fields of general anthropology is forensic anthropology. General anthropology traditionally includes four main subdisciplines: biological anthropology, archaeology, cultural anthropology, and linguistic anthropology. Forensic anthropology is a specialized area within biological anthropology that deals with the identification of human skeletal remains for legal purposes. It is not considered one of the four primary subfields that describe general anthropology's broad narrative and interdisciplinary approaches to studying the human experience.
