A sidenote:
Well, an autosomal "pure-bloodedness" (which does not concern the Nganasans, according to the qpAdm results by Zeng et al. 2023) can be a very recent phenomenon. Within only 7 generations the portion from one ancestor is (calculatively) less than 1 %, and within 10 generations it is less than 0,1 %. Still, paternal and maternal lineages can go back tens of thousands of years.
And in any case the Nganasans are a deviation, not a rule, even among the Samoyedic populations.
Hopefully we will find ancient DNA samples of N-P43, so we can see if it appears within the same population as N-L1026 in Europe. There probably were several east-to-west migrations during the metal ages.
Quote:"The bottom line is, Nganasans cannot be "pure-blooded" descendants of Proto-Uralic speakers if all Proto-Uralic-speaking males have belonged to Y-DNA haplogroup N-L1026 (or, somewhat more broadly, N-Z1957 [TMRCA 8,050 ybp]). There must either be something wrong with any autosomal analysis that has been taken as grounds for making such a claim of "purity," or the Proto-Uralic-speaking population must have included at least some males belonging to N-P43."
