The indigenous peoples of the Americas are the pre-Columbian inhabitants of North and South America, their descendants, and many ethnic groups who identify with those peoples. They are often also referred to as Native Americans, Aboriginals, First Nations , and (by Christopher Columbus' geographical and historical mistake) Indians, now disambiguated as the American Indian race, American Indians, Amerindians, Amerinds, or Red Indians.
According to the New World migration model, a migration of humans from Eurasia to the Americas took place via Beringia, a land bridge which connected the two continents across what is now the Bering Strait. The most recent point at which this migration could have taken place is c. 12,000 years ago, with the earliest period remaining a matter of some unresolved contention. These early Paleo-Indians soon spread throughout the Americas, diversifying into many hundreds of culturally distinct nations and tribes. According to the oral histories of many of the indigenous peoples of the Americas, they have been living there since their genesis, described by a wide range of traditional creation accounts.
