现代美洲原住民的线粒体DNA已被证明属于至少五个单倍型群（A，B，C，D或X）之一，其频率在部落群体中不同。这五个单倍群的频率在收集的古代个体从西内华达州追溯到大约350- 9200年BP。这些数据被用来测试假设，支持考古学和语言学数据，即目前的居民大盆地，努米克发言人，是最近移民到该地区谁取代了以前的非努米克居民。古代和现代美洲原住民的单倍型群频率分布差异显着，这表明古代居民和现代Numic扬声器之间存在遗传不连续性，为最近Numic扩展假说提供了进一步的支持。大盆地古代居民的线粒体单倍型群的分布与加州的一些现代美洲土著居民的线粒体单倍型群的分布最为相似。(C)2001 Wiley-Liss，Inc.
The mitochondrial DNA of modern Native Americans has been shown to fall into one of at least five haplogroups (A, B, C, D, or X) whose frequencies differ among tribal groups. The frequencies of these five haplogroups in a collection of ancient individuals from Western Nevada dating to between approximately 350-9,200 years BP were determined. These data were used to test the hypothesis, supported by archaeological and linguistic data, that the current inhabitants of the Great Basin, the Numic speakers, are recent immigrants into the area who replaced the previous non-Numic inhabitants. The frequency distributions of haplogroups in the ancient and modern Native Americans differed significantly, suggesting that there is a genetic discontinuity between the ancient inhabitants and the modern Numic speakers, providing further support for the Recent Numic Expansion hypothesis. The distribution of mitochondrial haplogroups of the ancient inhabitants of the Great Basin is most similar to those of some of the modern Native American inhabitants of California.
