Again, your dates are badly wrong. You might want to research this subject before you comment on it. In terms of the Eskimo and other aboriginal people who migrated into or across Beringia, the relevant dates would be: "It is believed that a small human population of at most a few thousand arrived in Beringia from eastern Siberia during the Last Glacial Maximum before expanding into the settlement of the Americas sometime after 16,500 years Before Present (YBP). This would have occurred as the American glaciers blocking the way southward melted, but before the bridge was covered by the sea about 11,000 YBP." https://en.wikipedia.org/wiki/Beringia https://en.wikipedia.org/wiki/Beringia This is extremely far north, as far north as 78.0 latitude, so again, you cannot put together a coherent theory that maps skin color to latitude in any simple way, therefore you need some additional theory, beyond UV rays, to explain the unique whiteness of northern Europeans.
