Spear Points Reveal New Story of How North America Was Populated

(From UPI)

New analysis of ancient spear points suggests the first people to settle North America took the Pacific coastal route, while the interior Canadian route remained unexplored until several thousand years later.

The traditional story of America’s peopling puts the first settlers on the interior Canadian route. As the ice-free corridor of interior western Canada emerged, the first Americans trekked across Alaska and Canada and into the Great Plains — that’s how the story goes, anyways.

But newer genetic studies of ancient Siberians, Alaskans and Americans have challenged the narratives, suggesting instead that the earliest settlers had made their way to southern Canada before an ice-free corridor made migration across Canada’s interior possible.
