Present-day anthropologists support the idea that American Indians have their origins in Mongolian ancestors who migrated across the Bering Strait. This theory suggests a historical connection between these two groups, emphasizing the migration patterns that shaped the indigenous populations of North America.

Barbara W. Tuchman, in her book "Bible and Sword: England and Palestine from the Bronze Age to Balfour," explores the implications of this migration theory, reflecting on how such movements have influenced cultural and historical narratives. This perspective invites further examination of the origins and development of American Indian societies.
