The naked truth about Dstat and Nganasan ancestry in Europe, updated

Maybe you are already bored of this issue, but I have to return to it, because it is so crazy and studies still use Nganasans to prove historical events in Europe.  It is also important to correct false conclusions.

In following tests I compare Nganasans, Native Americans, Europeans and some Asian populations and I prove that tests using Dstat and Nganasans are the craziest folly I have seen in population genetics.    My results imply that Nganasans went through a genetic drift during thousands years losing almost all ANE (Ancient North Eurasian) ancestry.  ANE is commonly found everywhere in Western and Northern Eurasian  and Native American people.   It is possible that they later got some genes from early Uralic speakers and albeit of the all  homogeneity they show in simplified comparisons the latest admixture event they have.

Update 26.4.18 10:20

After testing all available Siberians and their ANE/ENA ratios I found that actually Ket-people share highest drift with Finns, much more than Nganasans.  What probably is misleading people with Nganasans is that when comparing to other Siberians, the Finns share proportionally more drift with Nganasans than for example Lithuanians.  Still Lithuanians share more drift with Ket people than Finns with Nganasans.   My reckoning about this is that we (Finns) have received two Siberian migrations, the first one occurred when the Uralic language was brought to the Baltic Sea region and the second one via northeastern route and was forwarded by Saami people.
