How did humans reach the New World? For years, the ancestors of Native Americans were thought to have arrived near the end of the last ice age, 13,000 years ago. New archaeological finds have now pushed back the age of arrival beyond 15,000 years ago, 20,000 years ago... perhaps even earlier. This is the amazing story of the last great migration of Homo sapiens— the discovery of the New World.

This is quickly becoming one of my favorite channels.
