From 420 records of ethnic locations and movements since 2000 B.C., we computed vectors describing the proportions which peoples of the various European language families contributed to the gene pools within 85 land-based 5 x 5-degree quadrats in Europe. Using these language family vectors, we computed ethnohistorical affinities as arc distances between all pairs of the 85 quadrats. These affinities are significantly correlated with genetic distances based on 26 genetic systems, even when geographic distances, a common causative factor, are held constant. Thus, the ethnohistorical distances explain a significant amount of the genetic variation observed in modern populations. Randomizations of the records by chronology result in loss of significance for the observed partial correlation between genetics and ethnohistory, when geography is held constant. However, a randomization of records by location only results in reduced significance. Thus, while the historical sequence of the movements does not seem to matter in Europe, their geographic locations do. We discuss the implications of these findings.
从公元前2000年以来的420条种族位置和迁移记录中，我们计算出了向量，这些向量描述了不同欧洲语系的民族对欧洲85个陆地5×5度方格内基因库的贡献比例。利用这些语系向量，我们计算了85个方格中所有两两之间的民族历史亲缘关系，以弧距离表示。即使在作为共同影响因素的地理距离保持不变的情况下，这些亲缘关系与基于26个遗传系统的遗传距离也显著相关。因此，民族历史距离解释了现代人群中观察到的大量遗传变异。按年代顺序对记录进行随机排列，在地理因素保持不变的情况下，会导致观察到的遗传学与民族历史之间的部分相关性失去显著性。然而，仅按位置对记录进行随机排列只会导致显著性降低。因此，虽然迁移的历史顺序在欧洲似乎并不重要，但它们的地理位置却很重要。我们讨论了这些发现的意义。
