Thanks for the links, I'll take a look
Genetics didn't like it. Genetics seem to agree that America was populated by Northern Asians. Linguistic evidence suggests they came in at least 3 waves. The one that arrived first got all the way to tip of South America based. It is possible this wave arrived 35K years ago or earlier. But it's uncertain. This was followed another population around 12-14K years ago whose descendants formed the most of native american population in both North and South America. The second population genetically displaced or smothered the first population everywhere except southern parts of South America. Finally a third wave arrived last, probably around 12K years or less, and left their genetic indicators and linguistic traces in North western Canada and parts of US South west.
All seem to agree that the second wave, whose descendants really multiplied and formed majority of Native American population throughout both Americas, actually consisted of very small initial population at the time of crossing, and which had developed in genetic isolation from other people of the world since that time. As a result, the range of genetic diversity in the overall Native American population today is unusually low. This is why Native Americans exhibi unusual degree of consistency in susceptible to certain contagious diseases, as well as freedom from certain based diseases.
