| Aborigines were earliest known
inhabitants of a country. The term is generally applied to the original or
native inhabitants of a country, as opposed to a race from another area or
colonists and their descendants. Most nations have instituted measures for the
welfare of the aborigines within their territories. Such measures include those
of the U.S. and Canada concerning Indians and Inuits and those of Australia
concerning its aboriginal groups. All aboriginal peoples have been affected by contact with contemporary civilization; in some cases, the introduction of disease, warfare, alcohol, and drugs has demoralized and destroyed peoples. Others, such as the Ainu of northern Japan, have become almost wholly assimilated. The greatest degree of racial mixture has occurred among the native Polynesians of Hawaii.
