This is an interesting analysis that Dienekes carried out last year where he seems to think that the North/East Eurasian ancestry that is shared between Europeans and Native Americans can be tracked using ADMIXTURE at K=4. He calls this analysis globe4. In this he shows that most Europeans especially Northern Europeans show some Amerindian type admixture. This Amerindian admixture is obviously some very ancient type of ancestry that both present day Europeans and Native Americans share together. He released the calculator files for this analysis as well so we can post our results here and compare if you wish. Here are mine below.
90.08% European
1.13% Asian
0.22% African
8.57% Amerindian
