Roopkund Lake is a small body of water nestled deep in the Himalayan mountains. The Lake is known colloquially as Skeleton Lake due to the remains of several hundred ancient human scattered around its shores. The skeletons have never been studied so little was known of the origins.
Graduate student, Eadaoin Harney (Wakeley Lab) and researchers analyzed the remains using bioarcheological analyses (including ancient DNA, radiocarbon dating, stable isotope dietary reconstruction and osteological analysis) and discovered three genetically distinct groups deposited at different times approximately 1000 years apart. Of the 38 skeletons examined, 23 are typical of present-day South Asians, 14 are typical of eastern Mediterranean. The study published in Nature Communications refute previous suggestions that the skeletons were deposited in a single catastrophic event. Harney's study has been covered by National Geographic and The Atlantic,
