I suspect that the real reason that the Paiute's do not want the mummy DNA tested is because if it is Caucasoid, as is "Kennewick Man" it provides another data point showing that the Indians were NOT the first inhabitants of the North American Continent. So, the real reason is ethnic politics.
Of course there will be narrow parochial assertions made by the "White is Right" crowd as though this proves anything beyond the established evidence suggesting that North America has been inhabited much longer than the Lamestream Archaeologists wish to put forth and by more than one group having disparate geographical origins. Both groups are likely to have hissy fits.
I appreciate you bringing this to light, but this is hardly new news - One great book is Kyle Bristow's "White Apocalypse," one of my favorite reads of the last year and apparently he is coming out with a new book soon. He canvasses the Solutrean Hypothesis in this entertaining fictional book, and bold defenders of our people should be supported (IMO; autographed at bristow1@msu.edu)
One can glimpse the totalitarian nature of the Judæo-Liberal Orthodoxy by witnessing the dearth of information on the Solutrean Hypothesis. Like all great things in the history of humans, White's quite likely "discovered" The Americas thousands of years prior to Yellows wandering over the Aleutian Bridge. It wouldn't take long for your research grant to be pulled as an Archeologist if you lent any credence to the extant evidence.
Another good source is an old History Channel presentation, "Ice Age Columbus," which used to be available on YouTube and if not, I'd gladly send it to anyone via DropBox.
Keep fighting our fight... it isn't only right, it is true. Mike
