It's dubbed the Solutrean Hypothesis and it basically states that before the Mongloids crossed Beringia (Bering Sea when it was frozen). The Europeans crossed the Atlantic Ice Shelf chasing and living on monk seals way sooner. I believe they are the Long House Building Algonquian Speaking X Haplogroup in America A B C and D Haplogroups are all Mongloid. It all stems with some theory with the Clovis Point which I believe is the oldest civilization in America and it's ties to the same weapon in Europe. They have the Spirit Cave Mummies of Lovelock Nevada who were Giant red heads before the Mongloid tribes killed them off btw the Smithsonian Museum "lost" the Giant red headed mummies. Then you have the bog mummies and the list goes on and on but none of them get talked about. NAGPRA actually prevents mummies that have been found from getting a genetic sequence test btw NAGPRA means North American Grave Protection Right Act where the Native tribe leaders pretty much has the authority to prevent actual genetic testing to see who the first American skeletons belong to. One last thing their is actually a pretty good docudrama called the Solutreans and it's definitely not bad production value worth the watch.
