When mitochondrial DNA sequence variation is analyzed from a sample of 637 individuals in 14 European populations, most populations show little differentiation with respect to each other. However, the Saami distinguish themselves by a comparatively large amount of sequence difference when compared with the other populations, by a different distribution of sequence diversity within the population, and by the occurrence of particular sequence motifs. Thus, the Saami seem to have a long history distinct from other European populations. Linguistic affiliations are not reflected in the patterns of relationships of mitochondrial lineages in European populations, whereas prior studies of nuclear gene frequencies have shown a correlation between genetic and linguistic evolution. It is argued that this apparent contradiction is attributable to the fact that genetic lineages and gene frequencies reflect different time perspectives on population history, the latter being more in concordance with linguistic evolution.
当对来自欧洲14个群体的637个个体样本进行线粒体DNA序列变异分析时,大多数群体之间的差异很小。然而,与其他群体相比,萨米人在序列差异方面表现出相对较大的差异,在群体内部序列多样性的分布不同,并且存在特定的序列基序。因此,萨米人似乎有着与其他欧洲群体不同的悠久历史。语言归属在欧洲群体线粒体谱系的关系模式中没有体现,而先前对核基因频率的研究表明遗传和语言进化之间存在相关性。有人认为,这种明显的矛盾归因于遗传谱系和基因频率反映了对群体历史不同的时间视角,后者与语言进化更为一致。
