　　Roopkund Lake is a shallow body of water filled with human bones - the skeletons of hundredsof individuals.
　　路普康湖水体很浅，充满着人骨--数百个人的骷髅。
　　It's these that give the lake its other name, Skeleton Lake, and no one knows how the remainscame to be there.
　　因此这个湖有了另一个名字，骷髅湖。没人知道这些遗骸是如何到达这里的。
　　One hypothesis is that some catastrophe, a single event such as a powerful storm, hadbefallen a large group of people. But DNA analysis of 38 of the skeletons has turned that ideaon its head.
　　一个假说是某些灾难降临了一大群人，比如说强风暴这样的单次事件。但是对38具骷髅的DNA分析完全改变了这个说法的思路。
　　The remains appear to come from distinct groups of people from as far as the Mediterranean, and they arrived at the lake several times over a 1,000-year span.
　　遗骸似乎来自不同的人群，远的来自地中海。他们在1000年的期限中好几次到达了这个湖。
　　"Through the use of biomolecular analyses, such as ancient DNA, stable isotope dietaryreconstruction, and radiocarbon dating, we discovered that the history of Roopkund Lake ismore complex than we ever anticipated," said geneticist David Reich of Harvard MedicalSchool.
　　“通过使用生物分子分析，比如远古DNA、稳定同位素膳食重建以及放射性碳定年法，我们发现路普康湖的历史比我们预料的更为复杂。“哈佛医学院的基因学家大卫·赖希说道。

　　The story began to unfold a decade ago. Geneticist Kumarasamy Thangaraj of India's CSIRCentre for Cellular and Molecular Biology sequenced the mitochondrial DNA of 72 of theskeletons.
　　十年前，这个故事开始展开。印度科学与工业研究会细胞与分子生物中心的基因学家KumarasamyThangaraj测定了72具骷髅的线粒体DNA。
　　As Thangaraj and his late colleague Lalji Singh had expected, some of the skeletons had DNAconsistent with a local Indian origin.
　　正如Thangaraj和他已故的同事Lalji Singh预料的那样，有些骷髅的DNA与当地印度裔一致。
　　But some did not. Several skeletons appeared to have originated around West Eurasia.
　　但有些不是。几具骷髅似乎是起源于西欧亚大陆。
　　This analysis revealed three distinct groups. The largest consisted of 23 individuals with DNAsimilar to that of people from present-day India. Apart from this, they seemed geneticallyunrelated.
