The high proportion of Yakutia_LNBA type ancestry along with the strongly Uralic associated N1a1a1a1a L392 in some of the burials from the Rostovka site just east of the Koptyaki culture and presented in the Zeng paper provides some pretty suggestive evidence to me, considering the acknowledged southern (Sintashta-Andronovo) and eastern (Seima-Turbino) influences in the formation of Koptyaki.
No problem with that either. However, from the linguistic point of view that street seems to be a dead end. Yakutia_LNBA related adstratum/substratum in Uralic however might still be visible. I'm not sure if anyone has really been looking at that yet? Most material I've seen is about Uralic-Altaic or smthg.
The amount of WSHG in the Rostovka burials make me think if the migration of Yakutia_LNBA was based on a couple of waves, instead of just one. Following the migration model towards North in Finland, the first groups might have stayed in the areas East of Ural mountains, mixing with the typical Rostovka individuals, hence we have people like modern Mansi. The following waves just passed the future Mansi area and mixed with the locals West of Ural mountains, ending up having no WSHG. The N-Z1936 of Rostovka seem to have split into East and West Uralic sub lineages around modern Kazan, which might be about right also, taking into account the ancient, much more western speech area of Ugric, including of course Hungarian.
