11. Hmm, maybe some supporting evidence.

This is a reconstruction of ice coverage for land. Over a short period of time (a few thousand years) after the last glacial maximum, the ice sheets shrank and sea levels rose dramatically.

So your "sudden appearance across wide ranges" correlates well with the existing population moving inland at that time.

The Barbados levels are probably the best index to use for what would have happened to any human populations in the Americas at that time. See page 4 of this article and look at the remarkable two-hump figure:

The thin double-humped line is the corrected time version. The sea was rising very rapidly at that time.

So your theory seems to match well with the geological evidence.
