The earliest finds of humans in NA have Caucasian DNA. Looks like the first wave of the Yellow Peril was devastating to the original inhabitants. I was reading that the tribes in Alaska stopped all DNA research on their lands when the truth was discovered. No surprise their. Pretending to be the original inhabitants is a main linchpin of the grift.
Aren’t the caucuses in Asia?
The original inhabitants of NA, whoever they were, predate the Out of Africa Theory by 150,000 years or more - perhaps twice that
The Clovis were of the Solutrean stone culture, but they were not the first by any means. A Denisovian-Neanderthal-Human hybrids came even earlier they likely also crossed following the ice from Europe. There were Australo-Melanesians who populated South America are documented to the 300,000 years ago.
This whole field is topsy-turvy with the introduction of hDNA , mDNA, and blood group tracing, not to mention the consensus meme is badly injured and crumbling.
The Treaty and Aboriginal Tribal claims all hinge on their meme that they were created here. Obviously false, but the cannot be challenged since they are specifically mentioned in the Constitution - their Rights are sacrosanct - big error on the Founders part (because that left the rest of us hanging on SCOTUS for privileges which too many believe are Rights, but are not).
