New evidence suggests that the first settlers might have been Polynesians and Asians who inhabited the western end of North and South America while the eastern seaboard was settled by Europeans who arrived by boat； navigating along the ice pack that spanned the North Atlantic during the ice age and following the migratory birds that flew west。
