"So, it says they weren't the Indians ancestors. I read it, and maybe I overlooked it, but where does it theorize they were from? "Thanks! So, then, if I understand correctly, the issue is: Who got to North America first, right?The artifacts that are being found (Topper Site) are like those (forgot what they're called) found on the Iberian (Spain) penensula. Also, the Cactus Hill site.
My take on things are that there were Caucasian types coming to North America thousands of years ago from two different directions, through Asia (Siberia/Japan) and then across the European ice bridge and also 'hopping' along both coasts by boat. The Native Americans (as we know them today) did not arrive until about 6,000 years ago.
Ming, the first part of my screen name, is from mainland China. I have told her that the American Indians are the descendants from the people in Asia. So what I wanted to do was make sure I'm not giving her bad information (and I'd just like to know). My Grandmother (my Dad's mother) was 1/2 Cherokee. That would make me 1/8th Cherokee (if math applies to genetics like that, lol).
Now that my interest is piqued here, I'd appreciate it if you have any links to:
1. The migration of Asians to North America and the origin of North American Indians.
2. Your theory regarding Caucasian migration via the two routes.
In the meantime, I'll be doing some Google Searches, etc. to see what I can find.
Thanks, FRiend! 
Have a cup while you FReep !
