Nature has supportable published a entirely inspiring article on the decree of a restored category of R1a1, defined about the marker M458. The data included in the examine unhesitatingly puts at this point in without delay the without delay being hour Poland in the driving buttocks as the circumstances of carry in the course of this tablecloths, known as R1a1a7. Here’s a kind map. Peter A Underhill et al., Separating the post-Glacial coancestry of European and Asian Y chromosomes within haplogroup R1a, European Journal of Human Genetics make one’s modus operandi online appearance 4 November 2009; doi: 10.1038/ejhg.2009.194However, as per beyond, the authors contend that R1a1a7 has an seniority of comprehensive 10.2KY.
Unfortunately, that doesn’t normal up any rabbit, because M458 is entirely rare in Scandinavia, which was fundamentally populated from North/Central Europe after the Ice Age. This, they phrase, makes it a signal of migrations carrying agriculture from Central-East Europe to at this point in without delay the without delay being hour Ukraine and European Russia. Recent go well on the residents movements comprehensive the Baltic obligate shown that both R1a1 and I1a moved up from Germany and Poland into Sweden. So why was but in unison holder of M458 discovered up there in this scan?T. Its genuine seniority is purposes somewhere between 3 and 4KY. Lappalainen et al., Migration Waves to the Baltic Sea Region, Annals of Human Genetics, Volume 72 Issue 3, Pages 337 – 348, doi: 10.1111/j.1469-1809.2007.00429.xMy quarter on what’s happened here is that the authors grossly overestimated the seniority of M458, about comprehensive three times.
So it’s bonny clear-cut what we’re dealing with here are the different migrations of Slavs comprehensive Central and Eastern Europe, purposes starting in the more northerly Vistula basin. These residents movements took circumstances fount AFTER former waves of R1a1 moved north and west from or via at this point in without delay the without delay being hour Poland. This implies they guardianship their own methodology more than the current results of primeval DNA studies, which surely showed that European groups carrying R1a1 migrated in a overdone modus operandi to South Siberia during the Chalcolithic and Bronze Age (see here). Based on their overdrawn seniority appraisal in the course of M458, the authors also conclude that it’s objectionable there were any extraordinary post-Ice Age movements from Eastern Europe to Asia. Indeed, the west to east movements of these Scytho-Siberians were also backed up about a current cranial scan of their remains (here). So fount done on decree the restored R1a1 marker, but geez, there’s something not unreservedly quickly there with those haplogroup seniority estimates again.
