1. Intro

Libtard scientists keep fabricating silly theories about the origins of the Proto-Indo-Europeans (PIE). For example, Johannes Krause of the Max Planck Institute claimed that the PIE came from Iran in his 2021 book. Now, David Reich of Harvard University has implied that they came from somewhere in West Asia, south of the Caucasus.

This is nothing new, of course. Geneticists have disingenuously described PIE as non-European “Asian invaders” for years now. Perhaps this is an attempt to cover up the extremely politically incorrect history of the PIE, which is basically a multi-millennia genocidal rape rampage throughout Eurasia? Instead of claiming that Europeans were always evil rapist colonizers, which is the Left’s usual propaganda strategy, they claim that Europeans were actually raped and colonized by non-Europeans. Is it a humiliation tactic? Xenophilia? Self-loathing? “See, Europe has always been a continent of immigrants!”? I have no idea.

Still, I get the feeling that they’re about the ramp up the gibberish. I’m not sure how it will go down, since the Eastern European origin of the PIE has been conclusively proven via archaeology, genetics, and linguistics. The case is as good as closed and the only remaining debates are, to be frank, pedantic quibbling over minor details.

2. Basic summary

The summary of Proto-Indo-European origins is as follows:

  1. PIE were a mix of Eastern European Hunter-Gatherers (EHG, most closely related to modern Finnic people e.g. Karelians), and Caucasus Hunter-Gatherers (CHG, most closely related to modern Georgians).
  2. Both of these groups had significant Ancient North Eurasian (ANE) ancestry, meaning that PIE were at least half ANE.
  3. PIE culture was incredibly patriarchal and their male lineages were near-exclusively of EHG origin. So, their language was almost certainly of EHG origin, and the Caucasian influence came from these EHG guys’ CHG wives (see: https://www.academia.edu/39985565).
  4. The Yamnaya (3300-2600 BC) are regarded as the quintessential Late PIE population. They had ~55% EHG, ~35% CHG, and ~10% EEF ancestry.
  5. People with this Yamnaya-related ancestry spread all Indo-European language families around the world (except for Anatolian, which split from PIE before the Yamnaya culture arose).
  6. Populations with similar EHG/CHG mixed ancestry lived in Eastern Europe for thousands of years before the Yamnaya culture arose:
    – The Khvalynsk (4900-3500 BC) of the Middle Volga had ~15-30% CHG ancestry.
    – Hunter-gatherers (5300 BC) of the Middle Don had ~20-30% CHG ancestry (source: https://www.biorxiv.org/content/10.1101/2022.05.04.490594v1).
    – The Sredny Stog of Ukraine (4500-3500 BC) appear to have been genetically identical to Yamnaya (but we only have a few samples from this population).
    – Even Mesolithic Ukrainians seem to have had some minor CHG ancestry.
  7. People with mixed EHG/CHG ancestry also lived in the North Caucasus region from at least 4200 BC, e.g. the Vonyuchka and Progress cemetery people with 50/50 EHG:CHG ancestry (source: https://www.nature.com/articles/s41467-018-08220-8).
  8. Unadmixed CHG ancestry ceased to exist around 5000 BC due to an influx of people from the Levant, Anatolia, and Iran into the Caucasus.
  9. Late PIE were culturally influenced by these later, admixed Caucasus populations (e.g. the Maykop), but did not mix with them genetically.
  10. Most importantly, PIE did not have any Iranian* or Indian ancestry, while modern Iranians and Indians both have Yamnaya-related ancestry.

It is beyond obvious that the PIE race or ethnic group arose north of the Caucasus, on or around the Eastern European steppe, and as a result of admixture between EHG males and CHG females. Any arguments to the contrary are likely motivated by Leftist ideology or ethnic resentment. Claiming that the PIE came from Iran or India is like claiming that eggs come from pancakes.

* Technically, PIE who lived in the Caucasus region often show minor Iran-Neolithic-related ancestry in admixture analyses, but it’s a pretty insignificant amount.

3. Additional genetics nerd info: Precise origin of PIE?

Below is an admixture analysis featuring various PIE-related populations. The source populations are West Euro HG, East Euro HG, West Siberian HG, Early Euro Farmers, Caucasus HG, Iranian Neolithic, Levantine Natufian, Indus Valley Civilization, and East Asian.

The final unanswered question of the PIE origin story is when and where the EHG/CHG admixture took place. I suspect that it occurred in many locations and over many centuries but we currently don’t have enough data to say for certain. Unadmixed CHG ancestry was extinct by ~5000 BC and subsequent Caucasus populations had additional Middle Eastern ancestry, so they cannot be the source of CHG ancestry in PIE. I would guess that CHG ancestry in most PIE populations came via an already admixed EHG/CHG population, with ancestry similar to the Progress cemetery of the North Caucasus. Khvalynsk samples seem to prefer Progress-type ancestry over unadmixed CHG ancestry (see below).

This high-CHG Progress-type ancestry may not have been limited to the North Caucasus. David Anthony has argued that a currently unnamed hunter-gatherer population from the Volga estuary (see map below) are the source of CHG ancestry in PIE peoples. They date to 6200 BC and reportedly have the highest levels of CHG ancestry outside of the Caucasus — even higher than that of the Progress cemetery.

So, it seems that at least some CHG-EHG interactions were taking place hundreds of miles away from the Caucasus and within Eastern Europe. But, again, I doubt that we could pinpoint this EHG/CHG admixture to one location. In any case, we know that it happened sometime before 5000 BC, we know the approximate location, and we know the precise genetic makeup and homeland of their Late PIE descendants who spread all Indo-European language families around the world. The Proto-Indo-European mystery has been conclusively solved.
