Biological anthropology differs from cultural anthropology in that it looks at the role that genetics, history and evolution have played in making humans and societies into what they are today.

biological, anthropology focuses on the study of biological aspects of human beings, past and present. Physical anthropology is essentially a biological science; it often seems to have more in common with biology than with the other subfields of anthropology. The importance of this subdiscipline in anthropology, however, is its contribution to the holistic understanding of humans. Physical anthropologists focus on both the biological nature of, as well as the evolution of, humans. By studying primates, physical anthropologists are able to contribute to our knowledge about the evolution of our own behavior. Examining fossil hominids allows physical anthropologists to study and understand the evolution of humans as a distinct species. Human variability is another major focus of physical anthropology; physical anthropologists are concerned with human variation, such as the differences in hair and skin color, the differences in blood types, the relationship between behavior and health, as well as the distribution of genetic traits. Using knowledge gained through such studies contributes to increased health and the decreased spread of diseases.

is a scientific discipline concerned with the biological and behavioral aspects of human beings, their extinct hominin ancestors, and related non-human primates, particularly from an evolutionary perspective.[1] This subfield of anthropology systematically studies human beings from a biological perspective.

It is a branch of Anthropology which attempts to explore human mystery related to their origin, differentiation, diversities and distributions. With the advancement of genetical sciences, it becomes more and more biology oriented, and by virtue of it, its area of study got considerable extension. By considering the whole situations, it can be divided into the following sub-branches.
