What was the human hisory between North American Asia Eurasia and Europe before the 1450's?

About 12,000 years ago people from northeastern Asia began migrating to the Americas. They probably crossed the Bering landbridge, although some may have come by boat along the shore.
The only European contact was the Viking brief settlement in what is now Nova Scotia, Canada.
