Bong-outlier!


Using my own data to test some stuff, and I notice

1) My parents are both “outliers” from the Bangladeshis collected in Dhaka. Not too surprising, as my family is from low country Comilla, and more “East Asian” than usual.

2) My father is more “steppe shifted.” This always shows up in various analyses. And, it is not surprising. His maternal grandfather was from a Bengali Brahmin family (they all converted the previous generation).

3) Weirdly, I am quite near my father on this plot. Mendelian segregation I assume. I have a 23andMe and a SNP file generated from 30x WGS, and they land on the same spot. So it’s not some artifact.

  1. It seems most people from Eastern Bangladesh(Comilla, Chittagong, Sylhet etc.) are slightly more east Asian shifted, but also slightly more ANI shifted as well compared to other Bangladeshis. The ANI shift seems due to extra Steppe in eastern Bangladeshis.

    1. Yeah I’ve noticed a similar thing too re E Asian and being more ANI shifted in comparison to BEB samples.

      Maybe something to do with the eastern region’s generally more recent clearance of jungles and settlement, with founder ‘Indic’ population / individuals being from further West in Bengal region +/- more mid/higher castes, mixing with tribal groups. Comparison of Y-DNA proportions would be interesting.

      Speculative, but I also suspect the BEB samples collected by a GI/cholera research group may represent lower socioeconomic stata of society compared to most of the ex pat samples from other regions. So not necessary a like for like comparison for the different regions.

      Razib, could you plot all the other regional Bengali samples you have on that PCA?

      I know I sound like a broken record, but you’ve got a decent regional spread and it would be great to compare.

      I have a couple of Bengali samples from the Barak Valley in Assam – Silchar and Hailakandi, which seem similar to other Sylhetis without much extra E Asian (given their more Eastern location).

  2. Razib, potentially an off topic question but wanted to ask since you in a way are qualified to speak on this matter in some manner, is the framing that “Race is a Social Construct” true or not.

    As in sure we know we use this word to mean something and that meaning has been defined, molded, polluted, etc by human societies over time but is the concept itself a purely Social Construction, i.e. Human Invention.

    Or is it a taboo topic to ask this because saying No implies some form of Scientific Racism by somehow admitting Races exist (whatever their distribution and mix) regardless of whether or not Humans know of them.

    Thoughts?

    it’s a semantic shift on the part of a lot of population geneticists from what i can see. the main issue i have with the ‘race is a social construct’ is that most the public take a different lesson from it than pop gen ppl mean to indicate, so i think it’s deceptive.

    but i lost that war. it is well known that population genetics confirms the prior beliefs of the latest in SJW thinking. you can read all about it in the guardian.

    i am no longer a liberal anymore so the lying doesn’t bother me like it used to. the key is to gain power and just force people to parrot what you want them to say. they are weak of will, so it won’t be hard 🙂

  4. Anyone know how i can get commentator to speak to me? THat guy promised me to show some dna analyses+ i also what him to model with my g25 coordinates

  5. I have noticed that you have become pessimistic as of late.

    i’m optimistic about our enemies being crushed. make your proscription list. check it twice. if the enemies win, we all hang apart 😉
