Principal Component Analysis of mitochondrial haplogroup frequencies. The first two dimensions account for 46.38 % of the total variance. Grey arrows represent haplogroup loading vectors, i.e., the contribution of each haplogroup. Ancient populations included in this study: aXH: Xiaohe cemetery; aCA: Nomads from Kazakhstan (2,100–3,400 yBP); aKur: Siberian Kurgans (1,600–3,800 yBP); aPWC: Scandinavian Pitted-Ware Culture foragers (4,500–5,300 yBP); aLBK: German early Neolithic Linear Pottery Culture population(6,900–7,500 yBP);aNEE: North East European ancient people (3,500–7,500 yBP):aLB: Neolithic Lake Baikal population (6,130–7,140 yBP); aHM: Xinjiang Hami people (4000yBP); aHB: Chinese Shanxi Hengbei people (3000yBP); aMG and aLJ: late Neolithic Qijia Culture peopulions in Ganqing region of China (4000yBP); aXN: nomads from Mongolia (2500yBP). Detailed information on the ancient and modern populations is provided in Additional file 3: Table S3
