Pastoralism in East Europe

We have now quite large number of samples before the Yamnaya period in East Europe ( before 3300BC) to have some conclusions about the origins of pastoralism in Pontic Caspian steppe and forest steppe regions.

If we keep aside local hunter gatherer lineages and those associated with Maykop culture in North Caucasus, then we are left with haplotypes that are associated with South Caucasian farmers. Shulaveri Aratashen culture.
  • J2-M319 - an obvious farmer lineage, which usually is associated with Minoans but it's deeper origins are without doubt in historic Armenia. Absent in European farmers.
  • J2b2b from Eneolithic Moldova associated with migrations from east. This branch was never found in any Euro-Anatolian farmer site but was found in Mentesh tepe in northwest of Azerbaijan.
  • J2b2a1-L283 currently the oldest sample from this branch is from Yamnaya but there is little doubt that it was present in Eneolithic steppe also. It became part of Yamnaya communities, moved to west Balkans and had a successful founder effect there. It's parallel branch the J2b2a2 is a lineage found in farmers from Central Asia who from there moved to India. Thus, indirect evidence supports that it was a south Caucasian farmer lineage. Its hunter gatherer origin is less likely.
  • J1b - it was a west Caucasian hunter lineage. It could be a CHG lineage in steppe. But a farmer lineage can't be ruled out completely given that this branch was found in many farmers sites stretched from Pakistan to Crete. In steppe it was found in Volga region and Usatovo cultures.
  • J1-CTS1026 - similar to J1b uncertain affiliation. It's south Caucasian origin in steppe is without doubt.
Besides those cases there were also J1* in Karelia in hunter gatherer context. Those were almost certainly from CHG.
On the other hand, there was no single European farmers lineage found in Pontic Caspian steppe. Archaeologists believed that west Ukraine farmers played an important role in the introduction of pastoralism, but the genetic data do not support that idea. In west Ukraine Cucuteni Trypllia farmers we have G2a2a, G2a2b, E1b-L618, C1a2, I2a2a etc. None of them is found in steppe.
An unpublished sample from Nalchik proves that farmers from South Caucasus moved to north. Despite this southern input, the Eneolithic steppe was predominantly R1b-V1636 and I2-L699. This latter was a Ukraine hunter gatherer lineage in its deep origin.
What was the reason of the mismatch between autosomes and Y DNA is hard to say but a similar scenario occurred in main Europe where after an initial success, the G2 farmers lost their positions and I2 became more frequent. While the autosomes didn't change in a significant manner.
Those genetic results is supported by the linguistics data also. Sahala notice that the Sumerian word gud, gu meaning ox, bull is a good parallel with PIE *gou(s) meaning cow, ox. From which the Armenian word kov is derived.
Matasovic notice that the reconstructed PIE language morphology shares features with North Caucasian languages.
PS You can see the Caucasus Lower Volga cline on the map which had both CHG and South Caucasian farmers ancestry mixed with local hunter gatherers

The Yamnaya culture and it's legacy

Yamnaya was an Early Bronze Age culture (3300-2700BC) that expanded in Pontic Caspian steppe in East Europe. It is remarkable due to its homogenous population which contrasts to the diversity of the preceding Eneolithic (means Chalcolithic) cultures. In just 1000 years genes associated with Yamnaya culture reached what is now Portugal and western Mongolia, Britain and South-Central Asia. The scale of this expansion can be considered as one of the most important demographic events in West Eurasia after the invention of farming in Fertile Crescent. In 2022 Lazaridis et al. announced that all modern living IE nations languages can be derived from the Yamnaya.
In 2015 the first ancient DNA of Yamnayans was published and it became clear that they do not directly descend from Eastern European hunter gatherers. Roughly the half of their ancestry was from south, and the "Armenian like" term was used to label this southern part. Then in late 2015 the Caucasian hunter gatherers (CHG) were discovered. In 2016 Iranian Zagros Neolithic farmers were published and since then both those populations were used to model the Yamnayans.
Despite those statistical models the formation of Yamnayans gene pool was remaining an obscure subject. Finally in April 2024 two large papers dedicated to this subject provided more clarity. Various Neolithic and Eneolithic groups living in East Europe had both shared ancestry and differences. One group who was living from North Caucasus foothills to Lower Volga (site Berezhnovka ) was labeled as "Caucasus Lower Volga cline". CLV had both southern Caucasian hunters and farmers (Aknashen) ancestry.
I will dedicate a special topic to describe what is CLV but at this stage it's sufficient to say that Yamnayans had up to 80% of their ancestry from CLV. Not only Yamnayans but all Kurganic cultures (Sredni Stog, Khvalynsk, Cernabida, Usatovo) of eastern Europe and Balkans had the CLV ancestry mixed with various local European populations. For the case of Yamnayans the second part of their ancestry was the Ukraine hunter gatherers (UNHG), which made them similar to Sredni Stog. Even though the most important Y DNA's were missing in Sredni Stog which could mean that Proto Yamnaya's exact immediate geographic location is not found yet but shouldn't be outside from Don - Volga - Caucasus triangle. With more sampling we will learn the exact origin of the two most successful lineages. R1b-M269 and R1a-M417.
The samples from the new paper are not available yet but we have two samples from the forementioned CLV cline. They are from the Progress - 2 site in the North Caucasus (4500-4000BC, see the last map for the location). I used them to model various Yamnaya samples and got the same result as in Lazaridis 2024. More than 75-80% of ancestry in regular Yamnaya samples is from the Progress / CLV. Some outliers have extra ancestries which is normal given their location.
You may wonder how "Hittites from east, from historic Armenia" and "Yamnaya from CLV" are connected to each other? After all there is no evidence that Hittites and other Anatolian speakers descend from Yamnaya culture. What is the common shared ancestry between IE Anatolians and Yamnaya?
Another topic will be dedicated to this subject.
And at the end here is the list of Y DNA found in Yamnaya at this stage. R1b-Z2103 (west Asia Balkans), R1b-L51 (west Europe), R1a-M417 (Asia - Europe), I2-L699, J2b-L283 (west Balkans), R1b-PF7562 (Balkans Mycenean ) Q-L939 and isolated cases of J1 and R1b-V1636.

Hittites from east.

Before commenting the deeper origins of Indo Europeans proposed in the new Lazaridis 2024 paper I want to speak about the origins of Anatolians. Since the advent of paleogenetic it became clear that they can't be native to plain Anatolia. They could be either from east or from north-west. Since 2018 the accumulating data was giving clear preference to the eastern origins. From historic Armenia. But a doubt was still persisting, because the Balkanian route was not fully investigated. In 2023 Penske et al. has found a migration from steppe to eastern Balkans before Yamna around 4000BC but they didn't even discuss the possibility that they could be related to Hittites. It's because their autosomes were rapidly diluted having a limited impact in Bulgaria yet alone in Anatolia. Also the Y DNA associated to this migration the I2-L699 was missing from inland ancient Anatolian samples.

While a R1b-V1636 was found in Bronze Age Gaziantep quite close temporaly and geographically to the kingdom Armi mentioned in Eblaite texts around 2500bc. Hittites names have been discovered in this kingdom recently.
The V1636 was popular in CLV cline stretching from Caucasus to Lower Volga and was found in ancient Malatya and Sevan basin also.
Besides this R1b other haplotypes found in Bronze Age Anatolia also show self-evident eastern affiliation.
The J1-Z1828 who's subbranch BY94 can be an Iron Age Luwian lineage like the J2- L70 which itself is derived from the L25 a haplotype from east.
A J2-Z6065 which was found in Masis Blue in Neolithic Armenia. We have also bunch of of J2-M67 and G2-M406, even though this latter is related to Hattic people so it can't be interpreted as a prove of Hittites from east.
In conclusion all ancient Y DNA that we have in inland Anatolia do have an eastern origin, from historic Armenia and around. One of them is further from north of Caucasus region. Their autosomes are also shifted to east compared to the preceding periods.
One exception is the I2-P78 from MBA Yassi Tepe near Izmir, which is clearly from Mycenean Greece, so this person was almost certainly a Greek people representative who probably settled in western Anatolian coasts after the 2000BC. They are mentioned in Hittite texts as Ahhiyawa.
In sum we can now say with high certitude that Indo-European languages were spoken in Armenian Highlands at minimum the last 6300 years. The 4300BC is not a random number it's the date of the start of Late Chalcolithic associated with Chaff faced ware which had a tremendous impact on southern Anatolia. But not much on northern Anatolia where Hattic related people were settled since more earlier times. Probably since 5800BC.
But that would require another thread which I will do the next time.

Samples of Anatolian/Aegean origin from the Roman empire city Vimminacium in what is now the eastern part of Serbia

Samples of Anatolian/Aegean origin from the Roman empire city Vimminacium (Olalde 2023) in what is now the eastern part of Serbia. A large military camp was present in the city.

  • E-L791 is remarkable because it's very close to Napoleon's Y DNA. Another L791 from Roman era Croatia.
    Distance to: Croatia_Zadar_Roman_oLevant.SG:R3742.SG
    0.03003301 Greek_Cappadocia
    0.03236809 Greek_Central_Anatolia
    0.03434637 Greek_Crete_Heraklion
    0.03806465 Armenian_Gesaria
    0.03847296 Greek_Crete
  • I2-Y16419 is ultimately from Trialeti-Vanadzor culture. Based on genetics he was probably from Kesaria/Kayseri.
  • The presence of J2-L70 and J1-BY94 is without surprise. These two haplotypes expanded in Iron Age Anatolia most probably.
  • And the T1a2 could be local but in most likelihood, he was also from Anatolia.
Also, a lot of local Balkanian specific haplotypes like E-V13 with some Germanic ones.
Another evidence that Roman Empire had a significant impact on the genetics of South Europe. Read in more detail in the link below.

Remarks on the Van Urmia ware culture. VUC (2200-1400/1300BC)

Previously I already had a review on VUC. Here I will add some remarks on the frequently asked questions.

+ VUC is a sister culture of Trialeti-Vanadzor culture, it does not descend from it. Both descend from the same parent culture, but despite this they have differences. VUC had painted pottery, while TVC had a different pottery. The grave was directed north-south in VUC while TVC had a east-west orientation. And most importantly TVC were practicing cremation while VUC not.
+ How exactly migrated Proto VUC people is not clear. One option is via Araratian plain but the presence in Aji Chay river basin, toward the Ardabil region suggests that they could have entered from the Mughan region toward the sources of Aji Chay then moved downstream toward the Urmia basin, and then to Van.
+ Karmir-berd culture descend from VUC. We don't have samples from this culture. The Dzori geghi outlier can be related to it. The J2-YP879 from Keti LBA can be another descendant of Karmir berd culture.

+ Unlike the TVC the VUC do not have an evident progeniture. Over time new people settled in Urmia basin from north Mesopotamia and Central Iran cropping the territory of VUC people. You can witness this change with the genetics. Hasanlu MBA (a hypothetical VUC sample) is close to Assyrian - Armenians while the Hasanlu IA is close the Kurds. In most likelihood the regions that best preserved the VUC ancestry are in the eastern Van and northern and western Urmia. South and east of lake Urmia had too much genetic shift. This means that most plausible descendants of VUC culture should be searched in those regions.
+ During Iron Age in forementioned regions we have Biai people from which the Biainili term is derived. We have Armarili (another name Aramali ) supposedly near modern Salmas. According to Sargon the ruling dinasty of Urartu was from Armarili. We have Ayadi near modern Urmia city and Uayis with disputed location. It is quite possible that this Uayis is another name for Biai, which was pronounced as Væy - Vay. According to Petrosyan later terms like Vayoc' dzor are related to this Vay people name. A term that he links with Hittites though.
+ Based on this logic the Manna country doesn't seem to be a good candidate for being a direct descendant from VUC. It has too much Dinkha tepe 2 type ancestry related to Grey ware. Nevertheless, the Hasanlu IA had too much of R1b to be completely unrelated to VUC. One possibility is that some R1b moved further south and east and became part of Grey ware. And reexpanded later with them. This would explain high level of R1b in some Iranian populations like Lurs. Another reason is that some of Hasanlu samples are different genome wide. They are closer to older VUC profile and plot close to Armenians and Assyrians. You can see an example in the fifth chart. Overall, it seems that the Manna country had a multi-ethnic composition and more ancient DNA is needed from south of Urmia to understand better it's structure
