Traditional models have placed Clovis origins in Asia, though one controversial theory contends that Clovis progenitors may have migrated from Iberia (Spain, France, and Portugal). This theory suggests that the descendants of an Upper Pleistocene culture known as Solutrean were the first unquestionable inhabitants of the New World. The recent revitalization of a...

Immigrants from the Other Side? According to the Clovis-First theory, for decades the gospel preached by authorities on the peopling of the Americas, the first Americans walked across the Bering Land Bridge from Asia about 12,000 years ago, and after finding a corridor through the Cordilleran Ice Sheet--admittedly it wasn't an easy trip and the timing was tricky--descended into temperate North America. We know them by their classic fluted points, unlike any others in the world, they left at campsites on their journey south to populate Central and South America.
