Happy to share this amazing review paper by Bennett et al. 2024 (Dec. 03): "Reconstructing the Human Population History of East Asia through Ancient Genomics"

@SaudiArabian0 As Indians main ancestry is derived from the IVC, which in turn is mostly Iran_N like, they also carry the Basal Eurasian component (indirectly). – Deep East Eurasian among Europe_UP remains is mostly from the local Oase/BachoKiro_IUP like groups (basal East Eurasian).

@_Arbm_ @suso_car H1/H3 is found among modern South Asians, while H2 is found among West Asians/Europeans at low frequency. – E.g. H1/3 would have spread with an early Iran_N like group or earlier to South Asia, while another Iran_N like group spread H2 among West Asians etc. during the Neolithic.

@suso_car @Agamemnonuwa "Unknown hunter-gatherers". It referred initially to a "proto WHG-like" ghost population relevant for the Levant etc. – E.g. it is referring to Levant_UP, a derived lineage of Anatolia_UP/WEC.

@Agamemnonuwa @suso_car The haplogroup variation is independent from the model itself. It is just my interpretation. – IJ may have also been present among WEC2, next to LT and H more common in the eastern area; but yes. – UHG would likely also be IJ as well as C1 and G = 'unadmixed' Anatolia_UP.

@BmacIvc There are two scenarios; 1. suggests that the main ancestry of Iran_N is derived primarily from the deepest West Eurasian branch (WEC2) with subsequent Caucasus_UP and ANE, – 2. suggests that it is a combination of mostly Basal + minor Önge with later Caucasus_UP and ANE input.

@Ugra___ Possible, this is similar to our previous scenario on the Iran_UP and AASI/EEC cline during the UP. – To answer that, we need Paleolithic/Mesolithic South Asian samples. It is at least plausible.

@suso_car Iran_N had J, as well as R2, L, and H. Iran_UP may have been primarily L/LT and H, later an increase of J. – R2 was most likely introduced via ANE geneflow; the oldest R2 is so far found among Iran_N samples.

6/ For clarification, the Vallini et al. 2024 model displaying the divergence patterns of ancient Eurasians; WEC2 represents the deepest split among West Eurasians, with the remainder lienages being on the WEC branch:

@iosif_lazaridis @br_llm_lock Maybe it would be helpful to publish a short review/summary on all those scenarios with explanations why or why not this or that model is plausible. – This would also prevent certain misunderstandings by various groups.

@yajnadevam @iAstroCanopus Those are in fact deeply related (see Transeurasian hypothese). Or either from YR_N, Amur_N or Jomon or even SH_N respectively.

@dantidura @yajnadevam @iAstroCanopus If you mean the supposed specific Iran_N like group relevant for the formation of the IVC, which may have already lived close or within NW India; e.g. "Indus HGs", we do not have such samples yet. But hopefully we soon find/analyze them.

@dantidura @yajnadevam @iAstroCanopus IVCp emerged of Iran_N-like + AASI, later IVCp mixed with additional AASI. – There is no "IVC_N". We have one IVC sample with primarily Iran_N like ancestry.

@yajnadevam @iAstroCanopus No, because it was not Koreanic speakers which migrated, but group(s) with a (mostly) similar mainland makeup (Amur+YR_N). Furthermore, Japonic is generally associated with those mainland migration group(s). Specifically Yayoi. It is not a creol, although such early view existed.
