Answer:
biology.
Explanation:
Anthropology can be defined as the scientific study of humanity with respect to human biology, human behaviors, human societies, cultures, beliefs, survival and the evolutionary history of humans (Homosapiens) through time and space. There are various fields under anthropology and these includes Ethnomusicology, Biological anthropology, Linguistic anthropology, Sociocultural anthropology, Archaeology, Applied anthropology, Economic anthropology, and Visual anthropology.
On the other hand, sociology can be defined as a social science that deals with the study of the socio-cultural interaction of humans with respect to the structure, functioning and development of their society.
The main purpose of sociology is to develop and enhance human knowledge or understanding of important socio-cultural processes through the gathering and analysis of all aspects of the social life of the people living in a society.
Hence, the main difference between anthropology and many other social sciences such as human geography, economics, sociology, law, psychology, political science, etc., is that anthropology is typically concerned with human biology as well as human behavior.
