Answer 1

The Story of the First Americans When did modern humans colonize the Americas? From where did they come and what routes did they take? These questions have gripped scientists for decades, but until recently answers have proven difficult to find. New techniques of molecular genetic analysis, and a reinvigorated search for early archaeological sites across the western hemisphere, recently have led to some astounding results. From genetics we now know that a single population of modern humans dispersed from southern Siberia toward the Bering Land Bridge as early as ~30,000 years ago, and further dispersed from Beringia to the Americas after ~16,500 years ago. From archaeology, we know that the first Americans appeared south of the Canadian ice sheets by ~15,000 years ago, 2000 years before the emergence and spread of Clovis. The route taken by the first explorers appears to have been along the recently deglaciated north Pacific coastline.(Source: http://www.centerfirstamericans.com/who.php)
