Thanks a lot! Did you run this through PLINK?
So
all 9 Sinhala samples cluster the closest with Dravidian speakers (HG03667 is a Punjabi Dalit who clusters the closest with south Indians). Considering that the predominant Sinhalese caste is the Govigama, this set of 9 most likely includes them as well (going by simple probability). This suggests that all Sinhalese based in Colombo, regardless of caste are genetically closest to South Indians. This corroborates the following 23andMe results:
https://sldna.blogspot.com/2020/03/sinha...pdate.html
Do you know how to run IBD calculations? To see if there is more IBD segments shared with Gujaratis or Bengalis? These are the two debated predominant sources for the Indo-Aryan speaking ancestry of the Sinhalese (which came via a sea route in the BC period).
Also, is it possible to model the Sinhala samples with multiple source populations to see the closest fit. In the study, the closet fit created was with a combination of Bengali and Savara (table S1):
https://www.cell.com/cms/10.1016/j.isci....f/mmc1.pdf
Yet this was not spoken about or delved in further.
Finally, the study's conclusion of distant ancestry with the Maratha is very questionable. Because the Maratha themselves cluster the closest with South Indian populations on PCAs. This suggests that the Maratha are largely descended from a Dravidian speaking South Indian like population, but with additional minority ancestry from the north acquired during the historic period. This fits with the linguistic and anthropological evidence (Dravidian toponyms in Maharashtra and the Maratha following Dravidian kinship practices, just like the Sinhalese). This is the likely explanation for why they share relatively more IBD segments cumulatively with the Maratha. Although overall, they still share the most IBD segments, both large and small with Tamils.
