Neolithic" is not generally used to describe indigenous cultures in the Americas, see Archaeology of the Americas.

The usual theory of the settlement of the Americas is that earliest ancestors of the peoples of the Americas came from Eurasia over a land bridge which connected the two continents across what is now the Bering Strait during a period of glaciation, when the sea water level was lower. The number and nature of these migrations is uncertain but the land bridge is believed to have existed only until about 12,000 years ago, when the land bridge was flooded.[13][14][15]

Three major migrations occurred, as traced by linguistic and genetic data; the early Paleoamericans soon spread throughout the Americas, diversifying into many hundreds of culturally distinct nations and tribes.[16][17] By 8000 BCE the North American climate was very similar to today's.[18]

The Clovis culture, a megafauna hunting culture of about 11,000 B.P., ranged over much of North America and also appeared in South America has been identified by the distinctive Clovis point. Dating of Clovis materials has been by association with animal bones and by the use of carbon dating methods.

Numerous Paleoindian cultures occupied North America. According to their oral histories they have been living on this continent since their genesis, described by a wide range of traditional creation stories. However, genetic and linguistic data connect the indigenous people of this continent with ancient northeast Asians.


A Folsom point for a spear.The Folsom Tradition was characterized by use of Folsom points as projectile tips, and data from kill sites, where slaughter and butchering of bison took place. Folsom tools were left behind between 9000 BCE and 8000 BCE.[19]

Na-Dené-speaking people's entered North America starting around 8000 BCE, reaching the Pacific Northwest by 5000 BCE,[20] and from there migrating along the Pacific Coast and into the interior. It is believed that their ancestors comprised a separate migration into North America, later than the first Paleo-Indians. They migrated into Alaska and northern Canada, south along the Pacific Coast, into the interior of Canada, and south to the Great Plains and the American Southwest. They were the earliest ancestors of the Athabascan- speaking peoples, including the present-day and historical Navajo and Apache.
