最近的研究对家养绵羊的历史有了相当大的了解，但还没有扩展到古代绵羊标本。本文对河南二里头遗址出土的8具古羊遗骸进行了DNA分析。公元前2100-1800年）探讨古代绵羊的遗传结构以及古代绵羊与现代绵羊的系统发育关系。采用直接测序法和限制性片段长度多态性分析法分别对该遗骸的线粒体DNA控制区和编码区序列进行了分析。我们的研究结果表明，所有的古代绵羊都属于现代绵羊序列所定义的谱系A。系统发育分析表明盘羊（Ovis阿蒙）和乌利亚羊（Ovis vignei）的mtDNA与二里头古羊的亲缘关系不近。此外，我们的研究结果表明，古代DNA分析可以作为一个强大的嘟嘟在跟踪史前人口流动。(c)2006爱思唯尔有限公司保留所有权利。
Recent research has thrown considerable light on the history of the domestic sheep, but has not extended to ancient sheep specimens. In the present study, ancient DNA analysis was carried out on eight archaeological sheep remains recovered from Erlitou archaeological site in Henan Province (ca. 2100-1800 B.C.) to explore the genetic structure of ancient sheep and the phylogenetic relationship between ancient and modern sheep. We analyzed the control region sequences and coding regions of mitochondrial DNA from the remains by direct sequencing and restriction fragment length polymorphism analysis, respectively. Our results reveal that all ancient sheep belong to lineage A defined by modern sheep sequences. Phylogenetic analysis shows that neither argali (Ovis ammon) nor urial (Ovis vignei) mtDNA is closely related to Erlitou ancient sheep. In addition, our results suggest that ancient DNA analysis can serve as a powerful toot in tracing prehistoric population movement. (c) 2006 Elsevier Ltd. All rights reserved.
