Gunpowder is reinvented?

 Reading this study (-> link ) it comes to mind that gunpowder has been reinvented. When the reprocessed Yakut LNBA samples now show a similarity of 100% with Nganasans, 10% with Finns, 2% with Estonians and 0% with Hungarians, one can only say that these proportions match perfectly with, for example, the results of Haak et al. 2015. The only new thing here is the assumption that the Nganasan-type North Siberian genetic type originated in Yakutia in the Late Neolithic period.

The study connects this genetic type to the Seima-Turbino phenomenon. Seima-Turbino was a Bronze Age cultural phenomenon that spread from east to west across present-day Russia. Seima-Turbino has been assumed to be associated with the westward spread of Uralic languages, but is this phenomenon also related to the Late Neolithic or Early Bronze Age settlement of Yakutia in the  Eastnorth Asia and is it possible to tie straightforwardly 4000 years old minor genetic remains to the present?  I would appreciate to see YDNA results of those ancient Yakutians. Did they belong to N-P43 or to N-TAT.  Did Seima-Turbino burials belong to N-P43 or N-TAT? I prefer YDNA in  searching back thousands years.  

If it is now stated that the new samples fully correspond to the Nganasan genetics in terms of the interesting genetics, then it has been proven that the North Siberian genetic type has migrated westward in the northern tundra zone and the same genetic type has been observed as part of almost all the peoples of the northern coniferous forest zone of Europe from present-day Russia to Scandinavia, but it has not been found in the most southerly Hungarians. In my opinion, it would be worth studying the genetics of the more southern Finno-Ugric peoples, such as the Mordvins and Erzyas.

The original study is unfortunately behind the paywall, so the link is to a press article.  It would have been nice to see also detailed results, but the price was too much this time.
