The Tuniit culture(Dorset) died out in the XIc at latest(freeing up Greenland for Norse settlement), the group that died out in 1902 were Inuit. The transAtlantic connection isn't only supported by a mitochrondial lineage(one of five, found in eastern North America)(so not from sailors(female line)), but virtually identity between a European stone tool tradition and the proto-Folsom tools found in Virginia, which are quite inlike the Siberian microblade tradition. there is also a later period of connexion during the period of the Red Paint People/Maritime Archaic(who where succeeded by megalithic cultures in Europe and Mound Builders in North America). Likely, the Asia population came down the coast by ship, and since the food was on the coast they would have taken their time before moving inland. Linguistic evidence supports this(greater linguistic variation along the west coast of the Americas). Probably none of the original settlers belonged to ethnic groups we'd recognize today. -Wayne Chevrier
