Fifteen of the Roopkund Lake samples from the Harney et al. paper published today at Nature Communications made it into the Global25 datasheets. Look for the prefix IND_Roopkund here…
Their genotypes are freely available in a ~590K SNP dataset via the Reich Lab here. I might be able to run more of the samples at some point if and when they’re released in a dataset with more SNPs.
In any case, much like everyone else, I don’t have a clue how those Mediterranean migrants ended up in the Himalayas back in the 1800s, but I certainly do know where they came from. Most appear to have been from Crete, while others from mainland Greece. However, one of the individuals that I was able to analyze with the Global25 was almost certainly an Anatolian Greek. Below are a couple of Principal Component Analyses (PCA) based on the Global25 data. The relevant datasheet is available here.
I don’t yet have a strong opinion about the origins of the earlier, typically South Asian Roopkund dead. They may have been visitors from all over India, or members of different castes from northern India. A PCA with six of these individuals can be seen here. Any thoughts? Feel free to share them in the comments below.
