    I ran the model using the (presumably) V3 scaled coords you had Pm’d for the compact ancients+moderns run.

    The subcontinent is large and thus, itís very unlikely that the hunter-gatherers of the region were homogenous. This difference in the AASI found in NW ancients and AASI found in South Indian Tribals is reflected by the difference between AASI NW and AASI south.

    so I am assuming AASI NW will have some possible West Eurasian dna? and AASI south almost completely East Eurasian? is that right? Also from which region do they think AASI NW were present, mainly in Balochistan?

    Neither of the AASIs should really have West Eurasian. It’s just that AASI isn’t a homogenous component most likely and there are differences between the hunter gatherers living in the NW and the ones living in the South, despite both being East Eurasian. Region wise for AASI NW I’m not exactly sure, but other users can probably chime in about that.

    Basically they're sister populations. Both east eurasians, like east asian, but still different because of being apart for long time. Imagine two similar communities that branched off from same source and developed some mutations that gives them a separate identity.

    Finally uploaded DMXX's latest simulated AASI_S. Those replace the old AASI_South coordinates. You can check them individually using the dropdowns. Again, thank you so much DMXX for taking your time to simulate these.

    @Arjun,

    AASI was, ostensibly, a mostly autochthonous Subcontinental HG of deep antiquity (going back to the Achulean potentially). You haven't specified if you're focused on AASI on a conceptual basis, or on my simulations. I'll address both.

    There probably was some ANE-derived admixture in the Subcontinent at some point in prehistory (search my posts for a recent explanation of the basis of that hypothesis). Recently confirmed by Kale's qpAdm runs. As such, we'd expect heterogeneity in the component scores, once we get aDNA from across the Subcontinent. Given the substantial West Eurasian ancestry cline that exists between the Kalash to the Irula-Paniya, I would expect that hypothetical prehistoric ANE-derived admixture to increase the further one heads towards the Subcontinent's peripheries.

    Depending on how you read the archaeological data, you may infer that something related to Iran_N was present in the Subcontinent prior to the Neolithic West Asian agricultural wave reaching there. I personally don't subscribe to that idea (the material evidence is too scant + there's no obvious impetus for Iranian HG's to migrate eastwards + there are 4-5 mostly impermeable geographical barriers in the way between central Iran and the Ganges).

    There shouldn't be any West Eurasian within my NW_AASI simulation, as the qpAdm runs that Narasimhan undertook for those Afpak ancients satisfactorily addressed the prerequisite components. There also shouldn't be any in the S_AASI ones, either. However, there probably is surplus ANE present (Kale did a bunch of qpAdm runs that confirmed as much).

    @All,

    You're very welcome Poi, and thank you for uploading the files so soon.

    Here's a reasoned run with 262.., Censored, Kulin and Reza (individuals such as these gents will be the ones who benefit from the expansion of AASI_S).

    Running first without my simulations or a living proxy for AASI (let's called this the "GenePlaza-worthy" model). All runs cyc=1k, bat=500, pen=def:

    Code:
    	Sample	Details					Fit	Map		IRN Shahr I Sokhta BA1	LAO Hoabinhian	NPL Chokhopani 2700BP	RUS Sintashta MLBA	TKM Gonur1 BA	TKM Namazga Tepe En
    1	Bengali_Bangladesh:Kulin_AGUser	Modern;		7.694 	Open Map	13.4			61.4		0			4.2			18.8		2.2
    2	Bengali_Bangladesh:Reza_AGUser	Modern;		8.9554 	Open Map	15.8			64.4		0			1.4			17.2		1.2
    3	Brahmin_Tamil_Nadu_Mixed:26284729292_v3_AGUser	9.3652 	Open Map	47.6			41.2		0			0.8			10.4		0
    4	Custom:AGUser_censored				10.1407 Open Map	52.4			47.6		0			0			0		0
    Reza and Kulin, being ~60% ancient SE Asian with a fit of 10? Definitely GenePlaza-worthy.

    Now, without my simulations (replaced with the Onge, which we would've had to have resorted to a year ago).

    Code:
    Sample	Details								Fit	Map		IRN Shahr I Sokhta BA1	LAO Hoabinhian	NPL Chokhopani 2700BP	Onge	RUS Sintashta MLBA	TKM Gonur1 BA	TKM Namazga Tepe En
    1	Bengali_Bangladesh:Kulin_AGUser	Modern;				7.8941 	Open Map	5.8			37.8		0			24.2	9.6			19.4		3.2
    2	Bengali_Bangladesh:Reza_AGUser	Modern;				9.3278 	Open Map	7			47.8		0			18	7.4			17.4		2.4
    3	Brahmin_Tamil_Nadu_Mixed:26284729292_v3_AGUser			9.2133 	Open Map	50.4			1.8		0			39	2.2			6.6		0
    4	Custom:AGUser_censored						9.9598 	Open Map	54			5.6		0			40	0.4			0		0
    The fit either doesn't change or improves slightly, though the results don't make much sense, due to the inappropriate use of the highly-drifted Onge as an AASI proxy. Humourously, Lao_BA looks as good as the Onge based on this.

    Replacing Onge with my AASI_S:

    Code:
    	Sample	Details					Fit	Map		IRN Shahr I Sokhta BA1	LAO Hoabinhian	NPL Chokhopani 2700BP	RUS Sintashta MLBA	Simulated AASI South By DMXX	TKM Gonur1 BA	TKM Namazga Tepe En
    1	Bengali_Bangladesh:Kulin_AGUser	Modern;		3.0433 	Open Map	7.6			13.2		4.8			12.2			36.2				23.6		2.4
    2	Bengali_Bangladesh:Reza_AGUser	Modern;		4.0586 	Open Map	9			10.6		7.2			9.8			38.8				21		3.6
    3	Brahmin_Tamil_Nadu_Mixed:26284729292_v3_AGUser	4.0334 	Open Map	30.4			5.2		1			8.4			32.8				22.2		0
    4	Custom:AGUser_censored				3.4833 	Open Map	29.2			0		0			4.6			43.6				21.4		1.2
    Drastic improvements in the fits. Can we do better?

    Adding in AASI_NW:

    Code:
    	Sample	Details						Fit	Map		IRN Shahr I Sokhta BA1	LAO Hoabinhian	NPL Chokhopani 2700BP	RUS Sintashta MLBA	Simulated AASI NW By DMXX	Simulated AASI South By DMXX	TKM Gonur1 BA	TKM Namazga Tepe En
    1	Bengali_Bangladesh:Kulin_AGUser	Modern;			2.6927 	Open Map	5.2			19.8		5			13.6			8.8				22.6				21.2		3.8
    2	Bengali_Bangladesh:Reza_AGUser	Modern;			3.5705 	Open Map	6.4			24.6		2.8			10.8			11.6				20.8				20.2		2.8
    3	Brahmin_Tamil_Nadu_Mixed:26284729292_v3_AGUser		2.6733 	Open Map	27			5.2		2.6			11			11.8				20				22.4		0
    4	Custom:AGUser_censored					2.2382 	Open Map	32.2			3.6		1.2			10.2			13.4				24.6				14		0.8
    The fits have once more improved.

    You guys can probably find a more robust individualised fit for each individual, but that's a good start. There's probably a need for something WSHG-ANE-rich to account for the MLBA steppe inflation IMO, which could push things down to the excellent 1-2 fit range.

    Using DMXX's AASI (NW and now the South), draw S/SC Asian 2D PCA plots (including ancients)... this is mainly to see how various AASIs look:
