Below is a plot for a K = 13 admixture analysis that includes 45 ancient Near Eastern genomes.
This analysis produced five Caucasoid components. Three of them are similar to components in the preceding K = 12 analysis, while a fourth represents Western European hunter-gatherer DNA, and a fifth represents DNA from the hunter-gatherers of Eastern Europe and Western Siberia, and the later Copper and Bronze Age populations of Eastern Europe.
Over the past week I began to suspect that the Caucasus-related pine green component appearing in large amounts in European samples in my recent K = 13 analyses, which I thought was linked with the spread of R1b-L51 people, was somehow spurious. This analysis, along with others I’ve done over the past few days, confirms my suspicion. The plot below shows most European populations as having only small amounts of the Caucasus-related pine green component.
