The Division of Anthropology is dedicated to the study of human culture and biology. It was established in 1873, only four years after the founding of the museum. Members of the Division carry out ethnological research in Asia, Africa, North, Central and South America, and study such global topics as warfare and the origins of the state. One of the Anthropology Division's most important missions is the preservation of, and access to, the archaeological, ethnological, and physical anthropology collections, assembled from around the world by Museum personnel from the time the Museum's founding to the present day. The collections include more than 500,000 objects from cultures in the Americas, Africa, Asia, and the Greater North Pacific region. They are irreplaceable cultural documents that provide a window into the lives of the people who produced them, and they are resources to be used again and again as new questions are asked about the human experience.
