Ах да. Вот, кстати, генетики проводили исследования по останкам из археологической культуры с территории Германии(откуда произошло вторжение славян в сторону Дании до н.э.)
Interestingly, this picture could be also confirmed by expansion time of Y-chromosome subcluster R1a1a1-M458 [51]. Thus, one may exclude the migrationist assumption that Central European territories were populated by the Slavs only at the very beginning of sixth century, following whole scale depopulation of the northern areas of Central Europe [1]. Indeed, the data presented herein indicates that visible changes of material culture of Central Europe in the fifth century did not result from extensive demographic changes, but were rather accompanied by continuity of some maternal and paternal lineages between Bronze and early Middle Ages...The genetic similarity of most samples to modern western Slavic populations (as well as Austrians and Scots) gives support to the origin of Balto-Slavic in Bronze Age north-central Europe, and more specifically in the Lusatian culture.”.(Alena Kushniarevich , Olga Utevska , Marina Chuhryaeva, Anastasia Agdzhoyan, Khadizhat Dibirova, Ingrida Uktveryte, Märt Möls, Lejla Mulahasanovic, Andrey Pshenichnov, Svetlana Frolova, Andrey Shanko, Ene Metspalu, Maere Reidla, Kristiina Tambets, Erika Tamm, Sergey Koshel, Valery Zaporozhchenko, Lubov Atramentova, Vaidutis Kučinskas, Oleg Davydenko, Olga Goncharova, Irina Evseeva, Michail Churnosov, Elvira Pocheshchova, Bayazit Yunusbayev, Elza Khusnutdinova, Damir Marjanović, Pavao Rudan, Siiri Rootsi, Nick Yankovsky, Phillip Endicott, Alexei Kassian, Anna Dybo, The Genographic Consortium , Chris Tyler-Smith, Elena Balanovska, Mait Metspalu, Toomas Kivisild, Richard Villems , Oleg Balanovsky)
