The autoctonismo was raised in the last century by the Argentine Florentino Ameghino, was favored by the studies of Darwin on the origin of man.At the end of the century XIX Florentino Ameghino he made important contributions in the fields of paleontology and geology in his country. It also raised a hypothesis about the origin of the American man and the world in general. For him, the human would have evolved in the Argentine Pampas, and from this place I would have migrated to the rest of the planet. This postulate about the hominisation caused uproar, when it was introduced in 1879 in the first International Congress of Americanists, held in Paris.
