"American" Indians are neither native to this continent, NOR Indian NOR the "first" Americans here. They are descendants of Siberian hunter groups who migrated to this continent over the Bering straits: oriental Asians.
That came out publicly when DNA reared its scientific head. It sure blasted the hole out of the "poor native Americans" myth.
This continent had NO indigenous people but the FIRST humans here were Caucasian. They hunted mammoths. They would dig huge traps for them to fall into, then get in there to kill the beasts.
Thanks to archeological digs they found that some of the hunters didn't make it out of the trap. Their human remains showed skulls that were oval. Oriental Asians, "american indians" have ROUND heads.
The HAN Chinese (92% of all Chinese) also have ROUND nostrils. That's how other Asian Orientals can tell which is which.
If someone is half and half, then all bets are off.
Why the rant? These are Indians in India. Geez.
What was that all about? A bit much and out of context.
Show me one Caucasian skeleton that is older than 12,000 years old on the American continent. There are australoid skeletons. They were probably the first in Latin America. Native Americans who crossed the Bering Strait were genetically mixed, about 80% East Asian and 20% European. Apparently they mixed in Siberia before the came over.
