Here’s the model from Wikipedia:
This hypothesises similarities between the Solutrean industry and the later Clovis culture / Clovis points of North America, and suggests that people with Solutrean tool technology crossed the Ice Age Atlantic by moving along the pack ice edge, using survival skills similar to that of modern Eskimo people. The migrants arrived in northeastern North America and served as the donor culture for what eventually developed into Clovis tool-making technology. Archaeologists Dennis Stanford and Bruce Bradley suggest that the Clovis point derived from the points of the Solutrean culture of southern France (19,000BP) through the Cactus Hill points of Virginia (16,000BP) to the Clovis point…This would mean that people would have had to move from the Bay of Biscay across the edge of the Atlantic ice sheet to North America. Supporters of this hypothesis believe it would have been feasible using traditional Eskimo techniques still in use today….
In my opinion there’s all sorts of things crazy with this model. But genome blogger Diogenes has been harping on the possibility that a low level substratum component among Northern Europeans which has affinities to Siberians and Amerindians may be a remnant of the original European hunter-gatherers.
