What is the focus of biological anthropology?

The focus of biological anthropology is on understanding human biology and evolution. This branch of anthropology specifically investigates the biological and physiological aspects of human beings, including our genetic heritage, evolutionary processes, and how evolutionary adaptations have shaped human diversity over time. Biological anthropologists explore subjects such as human skeletal biology, primatology, and the evolutionary history of humans, offering insights into how our physical forms and biological functions have developed through natural selection and environmental influences.

In contrast, the other areas mentioned in the incorrect options pertain to different specializations within anthropology. The study of past human behaviors through artifacts relates to archaeology, while the exploration of social norms in modern societies is a focus of cultural anthropology. The examination of cultural expressions through art falls within the domain of artistic anthropology or ethnography, making the correct answer distinctly aligned with the scope of biological anthropology.
