Maps indicate the phylogeographic spread of a J2b2-L283 around 6 kya, 4 kya, 2 kya and in the present, and b E2a1-CTS1273 around 5–6 kya, 4 kya, 2 kya and in the present. Shaded in pink are the 80% HPD areas of the node locations inferred by Bayesian continuous phylogeographic analysis with Beast v1.10.4 software. White circles indicate the median locations of the nodes, while black lines indicate the branches of the maximum clade credibility tree.
