Chesapeake Discoveries and Human Migration

In 2012, archaeologists discovered ancient stone tools on an island off Maryland's coast, suggesting human presence 20,000 years ago, 5,000 years earlier than previously thought. This challenges the theory that the first Americans arrived via Beringia 15,000 years ago, indicating a possible earlier migration route.
