R1b & Yamnaya Culture History06/22/2005 DF27-1 Add Comment
DNA from the remains of nine individuals associated with the Yamna culture from Samara Oblast and Orenburg Oblast has been analyzed. The remains have been dated to 2700–3339 BCE. Y-chromosome sequencing revealed that one of the individuals belonged to haplogroup R1b1-P25 (the subclade could not be determined), one individual belonged to haplogroup R1b1a2a-L23 (and to neither the Z2103 nor the L51 subclades), and five individuals belonged to R1b1a2a2-Z2103. The individuals belonged to mtDNA haplogroups U4a1, W6, H13a1a1a, T2c1a2, U5a1a1, H2b, W3a1a and H6a1b. A 2015 genome wide study of 94 ancient skeletons from Europe and Russia concluded that Yamnaya autosomal characteristics are very close to the Corded Ware culture people with an estimated a 73% ancestral contribution from the Yamnaya DNA in the DNA of Corded Ware skeletons from Germany. The same study estimated a 40–54% ancestral contribution of the Yamnaya in the DNA of modern Central & Northern Europeans, and a 20–32% contribution in modern Southern Europeans, excluding Sardinians (7,1% or less) and to a lessor extent Sicilians (11,6% or less).
