Another key argument for Stanford and Bradley’s proposal is the complete absence of any human activity in north-east Siberia and Alaska prior to around 15,500 years ago.If the Maryland and other east coast people of 26,000 to 19,000 years ago had come from Asia, not Europe, early material, dating from before 19,000 years ago, should have turned up in those two northern areas, but none have been found.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.The entire district was condemned, and most of the structures razed, in preparation for a vast reservoir that was to cover the communities and farms that once stood along the old road.
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.
Still, the road's natural beauty and solitude make for a beautiful drive along its accessible portions.
And knowing what was once along the route gives a better appreciation of the character of the old road and the people who have lived along its edges.
Some genetic markers for Stone Age western Europeans simply don’t exist in north- east Asia – but they do in tiny quantities among some north American Indian groups.
Scientific tests on ancient DNA extracted from 8000 year old skeletons from Florida have revealed a high level of a key probable European-originating genetic marker.
