Ancient ‘lost world’ discovered off the US West coast rewrites story of first Americans who arrived 13,000 years ago

A remote ‘lost world’ off California‘s coast could rewrite the story of the first Americans. 

Hidden among the Channel Islands are 13,000-year-old human remains, ancient settlements and evidence suggesting some of the continent’s earliest inhabitants may have arrived by boat rather than crossing an inland ice corridor. 

If correct, the theory would overturn decades of conventional thinking that the first Americans crossed a land bridge from Siberia and traveled south through an ice-free corridor in western Canada

Instead, it suggests Ice Age humans reached North America thousands of years ago by following a coastal ‘kelp highway,’ using boats to move along the Pacific
