Biological anthropology is a subfield of anthropology that focuses on the biological aspects of human beings. This includes studying human evolution, primatology, human genetics, and the study of human variation and adaptation. Biological anthropologists often use a combination of biological, archaeological, and genetic evidence to understand the biological and evolutionary history of human populations. By studying the physical remains of past human populations, biological anthropologists can gain insights into the origins, development, and diversity of human populations over time.
