While there is general agreement that the Americas were first settled from Asia, the pattern of migration, its timing, and the place(s) of origin in Eurasia of the peoples who migrated to the Americas remain unclear.
Selvom der er generel enighed om at Amerika først blev bosat fra Asien, forbliver migrationsmønstrene, timingen, og oprindelsesstedet/oprindelsesstederne for de folk som migrerede til Amerika uklar(e).
