Sinhala Genetics

[agent_lime]

Someone have a paper to read about how Bengali and Sinhalese are closely related?

When you refer to bengalis, which caste/group are you referring to? It's very hard to refer to them all as bengalis.

Aren't most non-Brahmin Bengalis genetically very similar? The "outliers" would probably be guys from eastern (and maybe central) Bangladesh who may have a lot of East Eurasian. When making this post, I forgot that West Bengalis don't have a lot of East Eurasian like many East Bengalis do (or do they?) so I'd expect them to be like non-Brahmin West Bengalis with some extra AASI.

I don't know how much Bengalis changed genetically from the time that Sinhalas migrated from there, but based on my limited understanding, I'd assume they're like modern Bengalis (non-Brahmin ones) until shown otherwise.

How would that get to Sinhalese? I think it's most likely AA stuff coming from Bengali gene flow. Then again BEB samples have much higher NE Asian. One possibility is the migration from Bengal preceded NE Indian gene flow into modern Bengalis.

Couldn't it be some AASI-related component that gets misread as SE Asian?

Is that the same case with high-AASI groups in close proximity to Sinhalese, like the Tamils and Veddas? Then I can agree with you.

I get few Sinhalas in my matches earlier on FTDNA but not now. I have seen Sinhala match show up in Andhra Kamma samples before

Reza is most familiar with the BEB samples and other samples from Bengal in general. I think he would be the best to answer the W v. E Bengal aspect.
