Biological Anthropology also called Physical Anthropology and is characterized by the anthropological study of human behavior through observation of the human being as well as evidence of behavior and biology of his ancestors, whether hominids or not.
Being a complex science it is easy to understand why Biological Anthropology is divided into subdisciplines. Among the branches of study are: Anthropometry, Paleoanthropology, Primatology, Osteology, Paleopathology and Genetics. The practices in this field can occur both in skeletal remains and in living people.
