Bering Strait Theory, Pt. 5: The Theory Comes Crashing Down
The fact that the oldest site in the Americas was located almost 8,000 miles from the presumed gateway did not go unnoticed. One might have assumed that if the Bering Strait Theory were correct, and Paleoindians migrated from Asia, then the sites in South America would be much younger than those in North America, and the further north one excavated, the older the sites would be. But that had never been the case, as the accepted sites in Canada were even younger than those in the U.S. Indeed the archaeological evidence was pointed towards a migration, but a migration the other way.
With Clovis First now dead and with it the Ice-Free Corridor, Coastal Migration was now the only alternative. The new dates from Monte Verde had pushed back human occupation of the Americas to 14,800 years ago, but geologists had already determined that 17,000 years ago the coastal route was completely blocked by ice from Russia all the way to Seattle. The Paleoindians would have had to have sailed a distance of almost 3,000 miles alongside the massive ice sheets without being able to land. Even 16,000 years ago the coastal route would have been largely clogged with ice. Once again the Paleoindians would have had to race, this time in tiny boats through treacherous waters, if they were to reach Monte Verde in time to leave traces of their occupation.
The line was drawn once again by the Bering Strait advocates at 15,000 years ago, and it could not go back much further than that without the collapse of the whole theory. So this meant that according to the newest version of the Bering Strait Theory, the Paleoindians essentially sailed down the coast directly to Monte Verde, Chile, before later deciding to settle in the Americas. But as absurd as that idea was, new evidence was making even that far-fetched concept impossible.
