The aboriginal people in Canada are composed of the Inuit and Metis, the first nations. The words "Indian" and "Eskimo" are no longer used. Old Raven Beach and Blue Fish Cave are the earliest archaeological sites inhabited by human beings in Canada. Clovis culture, Plenot culture and pre-Dorset culture in ancient India were earlier than Native American and Inuit culture. Dropping tools, spears, pottery, bracelets, chisels and scrapers mark archaeological sites, thus distinguishing cultural periods, traditions and reduced styles of the Stone Age. Hundreds of indigenous peoples have developed trade, spiritual and social hierarchies. The mixed-race Mé tis culture originated in the middle of the17th century, when the First Nations and indigenous Inuit intermarried with European settlers. In the early days, Inuit had more limited interaction with European settlers. Various laws, treaties and legislation have been formulated between European immigrants and First Nations in Canada. The right of indigenous autonomy provides opportunities to manage history, culture, politics, health care and economic control within indigenous communities. At present, there are more than 600 recognized First Nations governments or tribes, including 1,172,790 2006 ethnic groups, which are spread all over Canada and have unique aboriginal culture, language, art and music. National Indigenous Day recognizes the culture and contribution of Canada's indigenous people. Among the first nations in all walks of life, Inuit and Metis have become outstanding figures in indigenous communities and become role models for shaping Canadian cultural characteristics.
