Below is a plot for a K = 12 admixture analysis that includes 45 ancient Near Eastern genomes.
This analysis produced four Caucasoid components, one peaking in European hunter-gatherers, one in the early Neolithic farmers of Asia Minor and Europe, one in the hunter-gatherers of the Caucasus region, and one in the hunter-gatherers of the Epipaleolithic Natufian culture of the Levant.
The plot shows the Mesolithic R1b, R1a, and J1 hunter-gatherers of Samara and Karelia in Russia as being very similar to the other Mesolithic European hunter-gatherers, but also as having some of the Caucasus-related component. The amount of this component increases in the people of the middle Copper Age Khvalynsk culture, and then increases further in the people of the late Copper Age and early Bronze Age Pit Grave culture.

Thanks to Genetiker who let me reblogg this essential serie of information that gives more than I ever expected to the Ancient History and answers for credibility of several written sources from 750 BC on forward. Stories that must have been told from one generation to the next in a long long line of generations.
