What is the plausibility of an additional Bering migration from Asia to the Americas somewhere between 3000 BC and 1500 BC? Not huge numbers of people but perhaps a few hundred to a few thousand. Clearly this would have to take place largely by boat as sea levels would not be substantially different than today.
If it is implausible, what POD would be needed to make it happen?
