What’s more, chemical analysis carried out last year on a European-style stone knife found in Virginia back in 1971 revealed that it was made of French-originating flint.Professor Dennis Stanford, of the Smithsonian Institution in Washington DC, and Professor Bruce Bradley of the University of Exeter, the two leading archaeologists who have analysed all the evidence, are proposing that Stone Age people from Western Europe migrated to North America at the height of the Ice Age by travelling (over the ice surface and/or by boat) along the edge of the frozen northern part of the Atlantic.
At the peak of the Ice Age, around three million square miles of the North Atlantic was covered in thick ice for all or part of the year.
Three of the sites are on the Delmarva Peninsular in Maryland, discovered by archaeologist Dr Darrin Lowery of the University of Delaware. A sixth was discovered by scallop-dredging fishermen on the seabed 60 miles from the Virginian coast on what, in prehistoric times, would have been dry land.
The new discoveries are among the most important archaeological breakthroughs for several decades - and are set to add substantially to our understanding of humanity's spread around the globe.
However, the seasonally shifting zone where the ice ended and the open ocean began would have been extremely rich in food resources – migrating seals, sea birds, fish and the now-extinct northern hemisphere penguin-like species, the great auk.
Stanford and Bradley have long argued that Stone Age humans were quite capable of making the 1500 mile journey across the Atlantic ice - but till now there was comparatively little evidence to support their thinking.
