Biological Anthropology is the study of human biology within the framework of human evolution, with an emphasis on the interaction between biology and culture.  There are several subdisciplines within Biological Anthropology. 

Paleoanthropology is the interdisciplinary approach to the study of early hominids--their physical characteristics, their chronology, the archaeological remains, etc.

Primatology is the study of the behavior and biology of nonhuman primates, including prosimians, monkeys, and apes.

Osteology is the study of the skeleton.  This focuses on the skeletal remains of past groups.  Paleopathology is a branch of osteology studies the traces of disease and injury in human skeletons.

Forensic Anthropology is an applied anthropological approach dealing with legal matters.  Forensic anthropologists often work with coroners and other law enforcement officials in the analysis and identification of human remains.
