New book reveals Ice Age mariners from Europe were America's first inhabitants | Smithsonian Insider
"Some of the earliest humans to inhabit America came from Europe according to a new book Across Atlantic Ice: The Origin of America’s Clovis Culture.
The book puts forward a compelling case for people from northern Spain traveling to America by boat, following the edge of a sea ice shelf that connected Europe and America during the last Ice Age, 14,000 to 25,000 years ago."
...Through archaeological evidence, they turn the long-held theory of the origins of New World populations on its head.
For more than 400 years, it has been claimed that people first entered America from Asia, via a land bridge that spanned the Bering Sea.
We now know that some people did arrive via this route nearly 15,000 years ago, probably by both land and sea.
...Groundbreaking discoveries from the east coast of North America are demonstrating that people who are believed to be Clovis ancestors arrived in this area no later than 18,450 years ago and possibly as early as 23,000 years ago, probably in boats from Europe. 
...In “Across Atlantic Ice,” the authors trace the origins of Clovis culture from the Solutrean people, who occupied northern Spain and France more than 20,000 years ago..."
