But would we still be just as diverse, perhaps even more so if we were purely descended from AASI/hunter gatherers? Compare for example AASI south to AASI northwest:

    "sample": "Simulated_AASI_South_by_DMXX:Average",
    "fit": 20.6155,
    "Simulated_AASI_NW_by_DMXX": 100,

    Now comparing a modern standard northwestern group to a scheduled caste group from the south.

    "sample": "Madiga:Average",
    "fit": 17.6634,
    "Khatri": 100,

    Tribal shifted AG member:
    "sample": "Custom:AGUser_Arlus",
    "fit": 14.4086,
    "Khatri": 100,

    The distance is actually less. The only people this doesn't apply to are extreme outliers like the Paniya or Irula but otherwise, the pattern is similar.
    The AASI NW and South are an average of the HG populations in those specific areas. They are theoretical. This in turn shows the genetic variation between the 2 groups. It seems what is connecting all of us are Iran_N, ANE, less the HG populations. The AASI classification only makes sense because we don't have good samples. Also Khatris are closer to other foreign groups.

    "sample": "Khatri:Average",
    "fit": 3.7663,
    "Pashtun_Averaged": 100,

    "sample": "Khatri:Average",
    "fit": 10.7971,

    This thread has turned into a compendium of modelling thoughts - that was quite a read.

    I'm trying to model Bangladeshis with ancients (and simulated AASI) but getting hopelessly muddled. Any input would be much appreciated.

    This is the best that I've managed to get so far.



    Rationale:

    Simulated AASI NW and S (the fit is a little better using only AASI NW but in the absence of a Gangetic AASI, I suspect I needed something more interior/tribal like)
    Simulated basal AA to cover austroasiatic
    SIS BA3 as pIVC / likely vector for migration into gangetic plains
    Gonur 1 for excess (?) BMAC
    Sintashta MLBA for steppe
    WSHG for excess ANE (+/- for NE Asian in Bengalis)
    Hoabinhian and Chokhopani for E Asian

    Does the above make sense? Is there any point in removing SIS BA3 for Sarazm + simulated AASI?

    This is the only run where I can get my mother's fit below 3 .. any suggestions as to how to improve hers further?
    - compared to some, she seems to prefer a bit more Gonur over purely SIS BA3

    Hoabinhian is very Onge/Jarawa like so I'm not sure it would reflect non AA East Asian very well.

    What is the story behind this sample? Is it part of the indigenous negrito population of SE Asia?

    It's from 6000BCE IIRC, so that would make sense.

    Hmm, does anyone know how long ago it was that the Andaman islanders got stranded where they are? I always believed them to be a very archaic population 10s of thousands of years old, but if there were Onge/Jarawa like people roaming SE Asia just 8,000 years ago it may not have been so long ago.

    Secondly, could it be argued that AASI or at least some form of it was not unique to South Asia, but rather extended into SE Asia as well? Onge is after all used as a proxy for AASI, and if these negritos are similar to Onge then there was probably some sort of cline imo

    This is something Ive always thought about-the idea that negritos/Onge are to AASI what Siberian hunter gatherer is to EHG.

    Can someone point me to the latest G25 sheet as well as member coordinate sheet? The one stickied is out of date.

    I think you need to use a modern like Han to account for NE asian. I would also replace Gonur with Dzarkhutan (though this is more of a personal preference). Also, you don't need the Lao_Hoabinhian since Simulated AA Basal already accounts for the SE Asian (Austro-asiatic) ancestry.

    Lao_Hoabinhian is negrito-like, whereas AA Basal, if I understand correctly, would be like the original AA people similar to isolated AA groups like Nicobarese or Shompen. Both are needed for Bengali and NE Indian groups.

    Simulated AA Basal is calculated from the non-AASI/Iranian neolithic components of isolated tribes like Juang/Bonda etc. That ancestry should already account for whatever incoming admixture Austro-Asiatic rice farmers brought into Southern Asia.
