Last Glacial Maximum
The Solutrean hypothesis on the peopling of the Americas claims that the earliest human migration to the Americas took place from Europe, during the Last Glacial Maximum. This hypothesis contrasts with the mainstream view that the North American continent was first reached after the Last Glacial Maximum, by people from North Asia, either by the Bering land bridge (i.e. Beringia), or by maritime travel along the Pacific coast, or by both.
