Abstract

The Tlingit from Southeast Alaska belong to the Northwest Coast cultural tradition, which is defined by regionally shared sociocultural practices. A distinctive feature of Tlingit social organization is the matrilineal exogamous marriage system among clans from two opposite moieties: the Raven/Crow and Eagle/Wolf. Clan and moiety membership are determined by matrilineal descent, and previous genetic studies of Northwest Coast populations have shown a relationship between clan membership and genetic variation of matrilines and patrilines. To further understand this association, in this study mitochondrial DNA sequences from the Tlingit (n = 154) were examined. By comparing mitochondrial DNA with moiety membership information, the authors explore the impact of marriage traditions among the Tlingit with their observable genetic variation. At the genetic level, the results support cultural persistence of Tlingit maternal moiety identity despite the negative impacts of European colonization. This study additionally illustrates the relevance of data derived from Tlingit oral traditions to test hypotheses about population history on the Northwest Coast.

Tlingit群的遗传多样性及亲缘关系。

来自阿拉斯加东南部的特林吉特人属于西北海岸的文化传统，这是由区域共享的社会文化习俗所定义的。特林吉特社会组织的一个显著特征是母系异族通婚制度，氏族之间的两个对立的部分:乌鸦/乌鸦和鹰/狼。氏族和部分成员是由母系血统决定的，以前对西北海岸人群的遗传研究表明，氏族成员与母系和父系的遗传变异之间存在关系。为了进一步了解这种关联，本研究检测了来自Tlingit (n = 154)的线粒体DNA序列。通过比较线粒体DNA和部分成员信息，作者通过观察到的遗传变异探索了婚姻传统对特林吉特人的影响。在遗传水平上，尽管受到欧洲殖民的负面影响，研究结果支持特林吉特人母亲部分身份的文化持久性。这项研究还说明了来自特林吉特口述传统的数据与检验西北海岸人口历史假设的相关性。

期刊介绍： Human Biology publishes original scientific articles, brief communications, letters to the editor, and review articles on the general topic of biological anthropology. Our main focus is understanding human biological variation and human evolution through a broad range of approaches. We encourage investigators to submit any study on human biological diversity presented from an evolutionary or adaptive perspective. Priority will be given to interdisciplinary studies that seek to better explain the interaction between cultural processes and biological processes in our evolution. Methodological papers are also encouraged. Any computational approach intended to summarize cultural variation is encouraged. Studies that are essentially descriptive or concern only a limited geographic area are acceptable only when they have a wider relevance to understanding human biological variation. Manuscripts may cover any of the following disciplines, once the anthropological focus is apparent: human population genetics, evolutionary and genetic demography, quantitative genetics, evolutionary biology, ancient DNA studies, biological diversity interpreted in terms of adaptation (biometry, physical anthropology), and interdisciplinary research linking biological and cultural diversity (inferred from linguistic variability, ethnological diversity, archaeological evidence, etc.).
