The Immigration from the north.

This theory indicates to poblamiento from the northern regions of America by means of successive immigrations of bands leather jackets–recolectoras of big animals, ace the Milodón (kind of to giant peresos), Mammoth and American horse. These groups would have arrived starting from about 12.000 - 10.000 years, in full glaciación of Wisconsin. This theory this laid the foundation in Alex Hardlicka's devises who it outlines the one poblament of America through the Strait of Beregin, in the north of the continent.

Hardlicka outlined the origin the American population's Alóctono, being of origin protomongoloide or mongoloid that crossed starting from the glaciación of Winconsin from

Asia to America in search of foods, the last groups would be the Eskimos. After strong investigations, great part of the theory was discarded, but the step still subsists to inclination of the Beringia.
