Ancient DNA analysis of two male skeletons from the Late Neolithic Bell Beaker site of Kromsdorf, Germany showed they belonged to Y-DNA haplogroup R1b. More specifically, one skeleton belonged to R1b (M343) with the testing of R1b1a2 (marker M269) having failed and the other skeleton belonged to R1b1a2. Both were ancestral for SNP U106. No other downstream markers were tested. The find is important because it links the widespread Bell Beaker Phenomenon (hereafter BB) with the most frequent Y-DNA haplogroup in modern Western European males. It is also important as R1b has not appeared in any Neolithic or pre-Neolithic ancient DNA to date.
