A comparison of anthropometric data recently collected from a modern population of Evenki and data collected from a group of Evenki at the turn of the century by the Jesup expedition (Boas 1903) reveals a pattern of significant changes over this time period. The modern Evenki exhibit larger sitting height and biacromial breadth but smaller bizygomatic and nasal breadth and a shorter face. Although the differences in the postcranial characters might be attributable to improvements in health and nutrition over time, those of the head and face might also indicate increased gene flow, perhaps from European populations. The comparative analysis of the anthropometric data was expanded to a multivariate approach by use of canonical variate analysis. This analysis was performed using data from the 10 populations sampled during the Jesup expedition along with the data from a sample of modern Evenki. In general, a pattern of relationships emerged, reflecting known population interactions and linguistic affiliations to a certain extent. However, the sample of modern Evenki differed substantially from all the other samples in the analysis. Although such a separation of the modern Evenki from this set of historical Siberian populations may be the result of a secular trend; it is also highly probable that it reflects new patterns of gene flow resulting from interactions and events associated with Russian colonial expansion and in this century the establishment of the Soviet state.
对最近从现代埃文基人群中收集的人体测量数据，与耶苏普考察队（博厄斯，1903年）在世纪之交从一群埃文基人那里收集的数据进行比较，揭示了这一时期显著的变化模式。现代埃文基人坐高和两肩峰间宽度更大，但颧骨间和鼻宽更小，脸也更短。虽然颅后特征的差异可能归因于长期以来健康和营养状况的改善，但头面部特征的差异也可能表明基因流动增加，或许来自欧洲人群。通过使用典型变量分析，将人体测量数据的比较分析扩展为多变量方法。该分析使用了耶苏普考察期间抽样的10个人群的数据以及现代埃文基人样本的数据。总体而言，出现了一种关系模式，在一定程度上反映了已知的人群互动和语言归属。然而，现代埃文基人的样本在分析中与所有其他样本有很大不同。虽然现代埃文基人与这组历史上的西伯利亚人群的这种分离可能是长期趋势的结果，但也极有可能反映了与俄罗斯殖民扩张以及本世纪苏联国家的建立相关的互动和事件所导致的新的基因流动模式。
