Biological anthropology, also known as physical anthropology, is a scientific discipline concerned with the biological and behavioral aspects of human beings, their related non-human primates and their extinct hominin ancestors. It is a subfield of anthropology that provides a biological perspective to the systematic study of human beings.
As a subfield of anthropology, biological anthropology itself is further divided into several branches. All branches are united in their common application of evolutionary theory to understanding human morphology and behavior.
Scientific physical anthropology began in the 18th century with the study of racial classification. In the 1830s and 1840s, physical anthropology was prominent in the debate about slavery, with the scientific, monogenist works of the British abolitionist James Cowles Prichard (1786–1848) opposing those of the American polygenist Samuel George Morton (1799–1851). The first prominent physical anthropologist, the German physician Johann Friedrich Blumenbach (1752–1840) of Göttingen, amassed a large collection of human skulls.
In the latter 19th century French physical anthropologists, led by Paul Broca (1824–1880), focused on craniometry while the German tradition, led by Rudolf Virchow (1821–1902), emphasized the influence of environment and disease upon the human body. American thought has evolved during the “four-field approach”, the inclusive research of the four sub-fields of Archaeology, Linguistics, Physical Anthropology and Cultural anthropology, based upon studies on the remains of the North American hominin clade.
