University of Copenhagen researchers Eske Willerslev, Mikkel Pedersen, and their colleagues found that this harsh route only became viable for human migration 12,600 years ago—when the first plants and animals showed up in the region. Meanwhile, archaeologists have ample evidence that people were living in the Americas long before then.
“We know conclusively that human groups were in the interior before that date—perhaps as early as 15,000 calibrated radiocarbon years before present—so it is highly unlikely that they came south through the corridor,” said Michael O’Brien, an anthropologist and current academic vice president of Texas A&M University–San Antonio, who wasn’t involved in the study. “A more likely scenario is that they came south along the Pacific coast.”
For the study, Pedersen and colleagues drilled sediment cores from beneath the frozen surface of two lakes in western Canada: Charlie Lake and Spring Lake. These were among the last areas to lose their ice cover when the two huge ice sheets that blanketed the region (the Laurentide and Cordilleran ice sheets) split during the end of the last glacial maximum, around 15,000 years ago. The retreating ice opened up a path some 1500 kilometers long into the interior of North America.

The results of the study suggest the route was only usable between 12,600 and 10,000 years ago. This narrow window is too late to match with the once-prevailing “Clovis First” hypothesis...
Recently, several before-Clovis sites have been discovered in the Americas. Fossilized feces more than 14,000 years old have been found in Oregon’s Paisley Caves. Stone tools alongside mastodon bones in Florida were recently found to be 14,550 years old. And much further away from northwestern Canada, in southern Chile, humans inhabited Monte Verde at least 14,000 years ago (and possibly even earlier).

Everyone knows the first Americans came over on the Mayflower.
People spread throughout the Paciifc islands without benefit of a land bridge. Given how small those islands are, it makes sense that some (or most) of this migration would have missed the islands and ended up on the west coast of the American continents.
“Fossilized feces”
When I cast my eyes on those words the first thing
that came into my mind was ‘Harry Reid’.
It’s also possible the “first Americans” were from Europe and not Asia...”Scientific evidence suggests...”
SUV’s
Excellent
Beat me to it! Good call!
Oh, I see that you are just another Alaskan trying
to shirk responsibility for providing a conduit for
illegal immigrants for all of these thousands of
years.
I thought they drove there?
“1491.”
That is what a crap fest looks like.
LOL
Im still going with descendants from Lemuria (the Shasta people ), space ship drop offs or Kon Tiki
Evolution says everyone came from African monkeys.
Creation says everyone came from God, who gave each of us a soul.
I’m going with the God explanation.
I see what you did there...
Not when fossil evidence says people where in North America 2500 years BEFORE the passage opened.
Very good! My thoughts exactly!
No one has absolutely any proof of how the Americas were first settled. It’s all pure speculation.
