They are thought to have come from Asia, through the Baring Bridge, and moved in the interior of the Americas through the gap in between the two large ice masses on the east and west. This theory has been debated though, both about the origin of the American Indians, and about the timing of their arrival, as there have been found multiple clues that suggest that people from Oceania also migrated toward the Americas through the Pacific, as well as migrating much earlier, almost ten times the time suggested.

The organization was also on a much higher level in Central and South America than in North America.
