*sigh*, I am appalled at the above drivel by the previous poster. First of all, there is plentiful evidence that the Southern American Indians of the North American Continent went in for cultivating grains in a big way, so they were hardly "palaeo". Even the Northernmost American Indians of that particular Continent went in for making lots of pemmican, which consists, partially, of lots of congealed,rendered/cooked animal fat, so they were hardly "rawists".
The Bering Strait is, incidentally, a very tiny fraction of the size required for a land-bridge between Europe and North America. Besides, there are the Aleutian islands which make the Bering Strait a lot shorter than it seems.
As regards Native Americans, they may have eaten a few raw animal foods at times, but they mostly ate cooked foods. Only the Inuit ate a reasonably high proportion of raw animal foods in their diet.
There is also an inferiority-complex among Caucasians which tries to invent ridiculous theories to get away from the fact that Caucasians conquered the Americas. One myth is that Caucasians had supposedly visited the Americas many thousands of years ago. Thor Heyerdahl was one such foolish proponent, since debunked(though evidence exists re Carthaginian and Roman artefacts). The other myth is that the relevant Caucasian in question was supposedly "descended" from a mythical Cherokee "princess" - the idea being that the Cherokee are most known, among NA tribes, of intermixture with Caucasians.
