传统社会通常被组织成称为“血统”、“氏族”和“部落”的血统群体。这些后裔群体中的每一个都声称有一个共同的祖先，这种祖先将该群体的成员与其他人口区分开来。为了检验这些群体内共同祖先的假设，我们比较了五个中亚人群的民族学和遗传数据。我们表明，尽管来自同一血统和氏族的人们通常拥有一个最近的共同祖先，但在部落层面上没有观察到这样的共同祖先。因此，部落可能是氏族的联合体，他们随后发明了一个神话祖先来加强群体团结。
Traditional societies are often organized into descent groups called "lineages," " clans," and "tribes." Each of these descent groups claims to have a common ancestor, and this ancestry distinguishes the group's members from the rest of the population. To test the hypothesis of common ancestry within these groups, we compared ethnological and genetic data from five Central Asian populations. We show that, although people from the same lineage and clan share generally a recent common ancestor, no such common ancestry is observed at the tribal level. Thus, a tribe might be a conglomerate of clans who subsequently invented a mythical ancestor to strengthen group unity.
