NOTE: The model I used here SUCKS. These are NOT accurate estimates of Yamnaya ancestry in most populations. I will make my own G25 model and publish an updated version of this article in future. Apologies for the poor information.

UPDATED: Analysis for EUROPE here: https://thuletide.wordpress.com/2021/10/28/proto-indo-european-yamnaya-corded-ware-ancestry-throughout-europe-updated-admixture-analysis-2021/

This article contains a regional breakdown of Proto-Indo-European ancestry in modern Eurasian populations, roughly divided into the groups listed below. If you think I missed any populations, let me know in the comments.

  1. Northwest Europe
  2. Northeast Europe
  3. Southwest Europe
  4. Southeast Europe
  5. Uralic (Finno-Ugric)
  6. Caucasus
  7. Caucasus (Indo-European)
  8. Central Asian
  9. Eastern Iranians
  10. Western Iranians
  11. India and Pakistan

For reference:
This admixture analysis uses Eurogenes Global25 Standard Calculator, which features the following ancient populations (some are modern proxies).

  • TUR_Barcin_N
    = Anatolian Neolithic Farmers (became Early European Farmers via migration)
  • TUR_Tepecik_Ciftlik_N
    = Anatolian Neolithics + Iranian Neolithics (as far as I know)
  • Dinka
    = Modern Nilotic Africans
  • ETH_4500BP
    = Ancient Ethiopians (East African)
  • Gambian
    = Modern West African
  • Han
    = Modern Chinese
  • IRN_Ganj_Dareh_N
    = Neolithic Iranians
    = Dzudzuanas + Ancient North Eurasians
  • IRN_Shahr_I_Sokhta_BA2
    = Bronze Age Iranians
    = Neolithic Iranians + Anatolians + Levantines
  • Jarawa
    = Modern Austro-Melanesians
  • Kura-Araxes_ARM
    = Bronze Age Caucasus/Middle Eastern civilization
    = Caucasus Hunter-Gatherers + Anatolian Neolithic Farmers
  • Levant_PPNB (Pre-Pottery Neolithic B)
    = Neolithic Levant
    = Fertile crescent civilization
  • MAR_Taforalt
    = Paleolithic Morocco
  • Nganassan
    = Modern Siberians
  • WHG
    = Western European Hunter-Gatherer
  • Yamnaya_RUS_Samara
    = Proto-Indo-European
  • Yoruba
    = Modern Subsaharan Africans



In this admixture analysis, PIE ancestry is represented by Russian Yamnaya samples. Although the Corded Ware PIE population was primarily responsible for spreading Indo-European language, culture, and genetics around the world, they had additional ancestry from Early European Farmers (~20%) and Western Hunter-Gatherers (~10%). Yamnaya represents the earlier, unmixed Proto-Indo-European stock.

Will update in future, let me know in comments if you want me to add any populations.
