The eastern European plain, has seen the comings and goings of many different groups, of Iranic, Uralic, Turkic, and Slavic origin. The current discontinuity between it and the Caucasus largely reflects the eastward settlement of eastern Slavs during the medieval period and has no relevance for prehistory.<br /><br />Also, it's not clear how Indo-Europeans entered northern Europe. There are three options on the table: from the Balkans, across the Caucasus or from the trans-Caspian steppe. <br /><br />We will know more about the timing and routes of the spread of the IEs as more aDNA becomes available.Dienekeshttps://www.blogger.com/profile/02082684850093948970noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-35260367155934139472012-08-21T11:25:03.446+03:002012-08-21T11:25:03.446+03:00"The latter have more of the Caucasus compone..."The latter have more of the Caucasus component, a probable legacy of the Bronze Age Indo-European invasion of Europe."<br /><br />There's hardly a need to explain this apart from geography.princenuadhahttps://www.blogger.com/profile/02165977957244158593noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-26489126514248490532012-08-21T04:39:18.153+03:002012-08-21T04:39:18.153+03:00The "Caucasus" in Poles and Russians is ...The "Caucasus" in Poles and Russians is Neolithic ancestry via the Balkans.<br /><br />It probably also includes Bronze Age admixtures from non-Indo European groups that settled in Southeastern Europe.<br /><br />You can see the cline between Poland and the Balkans produced by these admixtures on any half decent PCA/MDS plots. But there's never any cline between Poland and the Caucasus.<br /><br />The South Central Asian admixture in Kurds and Iranians makes sense too, and it arrived in West Asia with R-Z93, and with North European admixture, from the east.<br /><br />R1a1a expanded from the Volga delta region into Asia. Most of that was R-Z93, but probably also some R-Z283. It then moved around the Caspian Sea into Central and South Central Asia, along with North European autosomal admix, and then finally into West Asia.<br /><br />Everything is becoming clear thanks to a better understanding of R1a, which certainly comes from Neolithic West Asia, but expanded in number and diversity in Central Europe during the late Neolithic/Copper Age.Davidskihttps://www.blogger.com/profile/04637918905430604850noreply@blogger.com
