Anthropology

Anthropology is the science that explores the origins, the physical and society development, the cultural development, as well as the beliefs (religion and philosophy) of a species.

It was considered by 20th century and 21st century humans, as well as 25th century Klingons and Lyrans, as a "dead-end" discipline, one that led university graduates to either low-pay or dead-end jobs. But it was one of the specialities of an archaeology and anthropology officer.
