Figure 2. Principal Component Analysis of mitochondrial haplogroup frequencies.

Figure 2

The first two dimensions account for 41.5% of the total variance. Grey arrows represent haplogroup loading vectors, i.e., the contribution of each haplogroup. Red dots represent ancient populations described in this study: aUzPo, Yuzhnyy Oleni Ostrov and Popovo (7,500 uncal. yBP); aBOO, Bol'shoy Oleni Ostrov (3,500 uncal. yBP). Other ancient populations were labeled as follows: aEG, Confederated nomads of the Xiongnu (4,250-2,300 yBP); aHG, Palaeolithic/Mesolithic hunter-gatherers of Central/East Europe (4,250-30,000 yBP); aKAZ, Nomads from Kazakhstan (2,100–3,400 yBP); aKUR, Siberian Kurgans (1,600–3,800 yBP); aLBK, Neolithic individuals from Germany (7,000–7,500 yBP); aLOK, Lokomotiv Kitoi Neolithic individuals (6,130–7,140 yBP); aSP, Neolithic individuals from Spain (5,000–5,500 yBP); aPWC, Scandinavian Pitted-Ware Culture foragers (4,500–5,300 yBP); aUST, Ust'Ida Neolithic population (4,000–5,800 yBP).
