Tuscan-like farmer from late Neolithic Iberia
I found this Principal Component Analysis (PCA) in a theses published recently by Uppsala University (see here). It features an ancient human sample from the archeological site of El Portalón, near the city of Burgos in northern Spain. The theses refers to this individual as a late Neolithic farmer, which is probably another way of saying that his remains date back to the Chalcolithic or Copper Age. Indeed, I'm pretty sure that El Portalón is a Chalcolithic site.
Needless to say, it's a shame we don't know what this guy's Y-haplogroup was, because it's now generally believed that haplogroup R1b made its appearance in Western European during the Copper Age, and that it arrived there from somewhere in the east. By the way, his mtDNA belonged to haplogroup U5b1b, which is actually a marker typical of Western and Central European hunter-gatherers.
