>>4248006Balts and Slavs are actually the closest and more related modern populations populations to Proto-Indo-Iranics, both share common ancestry by the Middle Dnieper culture, and other eastern Corded Ware groups (like Baltic CWC), both of their lineage have a common ancestor which is R1a-Z645, later some dispersions begin with the Fatyanovo-Balanovo culture. The Scandinavian and Insular Celtitc you usually see on that famous goy25 analysis is due to mathematical algorithms and shit, as well balance of the components (North Germanics and Insular Celts have an equilibrium and quantity of its components which results similar to the one of Proto-Indo-Iranics, and Balto-Slavs have a significant and higher WHG ancestry which correlates with that), and other reasons like when some people use Bell Beaker or CWC as a WSH proxie instead of actual proper and pure Steppe sources (like Sredny Stog Yamnaya Poltavka Catacomb Khvalynsk Repin Dereivka Novodanilovka Russia/Ukraine Steppe Eneolithic Vonyuchka 1 and Progress 2, et cetera).
