Radical new theory of first Americans arriving by boat

Excerpts of "Radical theory of first Americans places stone-age Europeans in Delmarva 20,000 years ago" by Brian Vastag, Washington Post

When the crew of the Virginia scallop trawler Cinmar hauled a mastodon tusk onto the deck in 1970, another oddity dropped out of the net: A dark, tapered stone blade, nearly eight inches long and still sharp.

Forty years later, this rediscovered prehistoric slasher has reopened debate on a radical theory about who the first Americans were and when they got here.



Archaeologists have long held that North America remained unpopulated until about 15,000 years ago, when Siberian people walked or boated into Alaska and down the West Coast.

But the mastodon relic turned out to be 22,000 years old, suggesting the blade was just as ancient.

Whoever fashioned that blade was not supposed to be here.

Its makers likely paddled from Europe and arrived in America thousands of years ahead of the western migration, argues Smithsonian Institution anthropologist Dennis Stanford, making them the first Americans.

's feasible," said Tom Dillehay, a prominent archaeologist at Vanderbilt University. "The evidence is building up, and it certainly warrants discussion."

At the height of the last ice age, Stanford says, mysterious Stone Age European people known as the Solutreans paddled along an ice cap jutting into the North Atlantic. They lived like Inuits, harvesting seals and seabirds.

The Solutreans eventually spread across North America, Stanford says, hauling their distinctive blades with them and giving birth to the later Clovis culture, which emerged some 13,000 years ago.

When Stanford proposed this "Solutrean hypothesis" in 1999, colleagues roundly rejected it. One prominent archaeologist suggested that Stanford was throwing his career away.

But now, 13 years later, Stanford and Bruce Bradley, an archaeologist at England's University of Exeter, lay out a detailed case — bolstered by the curious blade and other stone tools recently found in the mid-Atlantic — in a new book, "Across Atlantic Ice."

At the core of Stanford's case are stone tools recovered from five mid-Atlantic sites. Two sites lie on Chesapeake Bay islands, suggesting that the Solutreans settled Delmarva early on. Smithsonian research associate Darrin Lowery found blades, anvils and other tools found stuck in soil at least 20,000 years old.
