One of the long-standing debates in anthropological research is the timing of early human migration and peopling of the Americas. We thought we knew that the ancestral Native Americans came from central Siberia, and that they migrated eastward across the Bering Straits about 13 000 BP. However, recent studies from genetics on human populations and the discovery of new occupation sites have challenged the conventional model and the earlier time framework in favor of an earlier human migration into the American continent. The paleomagnetic analyses of the volcanic ash near the Valsequillo basin (Puebla) yield strong evidence of the early arrival of humans in America.
