Haplogroup R1a, or haplogroup R-M420, is a common Y DNA haplogroup in many parts of Eurasia. One sub-clade (branch) of R1a, haplogroup R1a1, is much more common than the others in all major geographical regions. R1a1, defined by the single-nucleotide polymorphism (SNP) mutation M17, (and sometimes alternatively defined as R-M198), is particularly common in a large region extending from South Asia and southern Siberia to Central Europe and Scandinavia . The R1a family is defined most broadly by the SNP mutation M420, which was discovered after M17. The discovery of M420 resulted in a reorganization of the lineage in particular establishing a new paragroup (designated R-M420 *) for the relatively rare lineages which are not in the R-SRY10831.2 (R1a1) branch leading to R-M17. A large, 2014 study by Underhill et al., using 16,244 individuals from over 126 populations from across Eurasia, concluded there was compelling evidence, that R1a-M420 originated in Iran. 〔http://www.nature.com/ejhg/journal/v23/n1/pdf/ejhg201450a.pdf〕 ==The data on DNA-archeology == Haplogroup R1a was found in the remains of the Corded Ware culture〔(Haak W.
