Archaeologists have long held that North America remained unpopulated until about 15,000 years ago, when Siberian people walked or boated into Alaska and then moved down the West Coast.
But a mastodon relic found near the mouth of the Chesapeake Bay turned out to be 22,000 years old, suggesting that the blade found with it was just as ancient.
Whoever fashioned that blade was not supposed to be here.
Its makers probably paddled from Europe and arrived in America thousands of years ahead of the western migration, making them the first Americans, argues Smithsonian Institution anthropologist Dennis Stanford...
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...
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.
Further, the Eastern Shore blades strongly resemble those found at dozens of Solutrean sites from the Stone Age in Spain and France, Stanford says. “We can match each one of 18 styles up to the sites in Europe...
