A recent genetic study of Amerindians points to a common ancestor 18,000 years ago. This means that the migration to the Americas happened sometime after that date.

That is true the Amerindians originated within the last 18K years, but what if an EARLIER PEOPLE inhabited the Americas for thousands of years and disapeered at the same time all of the large animals did? Maybe the Amerindians came centuries after this first population suddenly died out.
