Davidski at his Eurogenes blog notes an interesting disconnect between ancient DNA from the early Bronze Age in Armenia (a.k.a. the Kura-Araxes culture) and the Middle Late Bronze Age in Armenia.
The early Bronze Age ancient DNA from Armenia is pretty much what you would expect:
Armenia_EBA or Kura-Araxes shows strong affinity to Caucasus populations, particularly those from the Northeast Caucasus. This is very cool, and it makes a lot of sense, because historical linguists and archaeologists generally consider Kura-Araxes people to have been early speakers of Hurrian, an ancient language thought to be closely related to present-day Northeast Caucasian languages.
Hurrian and some languages that were probably related (e.g. Hattic) were the principle languages of Anatolia and the highlands near Mesopotamia before the linguistically Indo-European Hittites came along and conquered essentially all of Anatolia, the Northern Levant and northern Mesopotamia. There is good reason to think that the Minoan language also had linguistic family ties to one or more of the non-Indo-European, pre-Hittite languages of Anatolia.
But, the Middle Late Bronze Age Armenian ancient DNA unexpectedly has strong affinities to modern day Latvian and Swedish populations. What contemporary populations could have led to these affinities in the Middle Bronze Age?
Following some statistical testing, he finds that this new component of their ancestry "may have also been closely related to the Sintashta people of the Middle Bronze Age Ural steppes, who do appear very Northern European in terms of genome-wide genetic structure. The time frame fits, so does the expansive and militaristic nature of the Sintashta Culture (see here)." His analysis finds that the Middle Bronze Age Armenians had about 20% Sintashta ancestry with the other 80% from the earlier Early Bronze Age population of the region. The link in his post recounts some of the pertinent information from a new book on the topic by David Anthony (citations in the text omitted in the quotation below):
The violent and transformative Sintashta period, 2100 to 1800 BC, saw the concentration of dispersed MBA mobile herder populations into MBA II fortified settlements east of the Urals, and this settled Sintashta phase ushered in the settled Petrovka-Alakul economy as well as the artifact and grave types of the early LBA Andronovo horizon....Sintashta-Petrovka chariot-driving chiefs contacted the irrigated civilizations of Central Asia (Bactria-Margiana Archaeological Complex [BMAC]), shown at the Petrovka settlement of Tugai near Sarazm and Petrovka-style ceramics inside the walled BMAC town of Gonur. Perhaps Ural copper and steppe horses were exchanged for Asian luxury goods (textiles?) for distribution to local steppe allies. The geographic expansion of Petrovka-style sites from the southeastern Ural steppes into the Zeravshan Valley in Central Asia was the foundation for the later development of Andronovo styles across Kazakhstan....After the formation of the almost pan-continental Srubnaya-Andronovo cultural horizon, beginning around 1900 to 1800 BC, innovations that included bronze casting, chariotry, and some aspects of pastoral subsistence and settlement types began to diffuse between regions that had formerly appeared materially isolated, encouraging the movement of commodities such as copper, tin, and horses and enabling the more patchy diffusion of cultural traits, including language, rituals, and packages of distinctive elite behaviors. At its eastern end, the Andronovo network interacted across the Tien Shan with what is today northwestern China during the rise of the earliest Chinese state in the late Quijia, Erlitou, and early Shang periods and with Central Asia during the declining centuries (1800–1600 BC) of the BMAC and Namazga VI cultures.
The Sintashta culture population's ancient DNA as a source for the Middle Bronze Age demographic shift in Armenia is preferred in statistical comparisons relative to other candidate populations which he labels Potapovka, Corded Ware from Central Europe, Poltavka, Andronovo and Srubnaya populations.
This part of the world was not literate in this era, so there is no historical record of a major invasion or conquest as far as Armenia by chariot driving warriors from the Ural Steppes, and there isn't really any strong archaeological pointer to this significant population upheaval. But, the ancient DNA evidence and what we do know about the archaeological cultures in existence at the time certainly supports Davidski's inference.
This also suggests that one of the reasons that people in the Caucasus mountains look more Northern European than you would expect, for example, from comparing them to nearby Iranians, is that a significant share of them received a significant infusion of Northern European ancestry in the Middle Bronze Age.
This Middle Bronze Age event would also be a plausible historical moment for a language shift from Hurrian or a related language to an Indo-European language such as an early version of the Indo-European Armenian language.

I'm not sure I'd go with the appearance assumption re: the Caucuses. What I think David's work shows is a strong case for Sintashta as the origin of all Satem languages - including Persian.
ReplyDeleteInteresting hypothesis.
ReplyDeleteI am Azerbaijani, I just found out that I am close to the population who lived in the Bronz Age (via DNA test). But it should not be called Armenian MBA. Armenians came from Balkans.

ReplyDeleteWell, in the academic papers the ancient DNA samples from the territory of the modern Republic of Armenia (RoA) are all labeled as "Armenia" instead of "Armenian". Andrew apparently favors the Middle Bronze Age arrival of Armenians to what is now the RoA and environs, that must be why he wrote "Armenian" instead of "Armenia" when talking about the Middle and Late Bronze Age samples from there.
Anyway, even if Armenians came to the historical Armenian lands from the Balkans during the Iron Age, modern Armenians are also largely descended from the Bronze Age peoples of those lands as modern Armenians are also genetically close to the Bronze Age samples from the RoA.
In my humble opinion, Armenia has one of the trickiest and most complex pre-historic periods in West Eurasia, certainly linguistically. I will try to post about it when I get a chance.

ReplyDeleteAzeri is, I believe, alluding to a popular hypothesis for the origins of the Armenian people (or at least their language and one key genetic component of the Armenian people), which is almost conventional wisdom and dates to antiquity. According to this hypothesis, the core of the Armenian language (which subsequently probably had multiple language contact based influences which make it hard to match to an Indo-European language subfamily) derives originally from a a folk migration of people from the Balkans to the Caucuses via Anatolia, in the wake of the collapse of the Hittite Empire, around the time of Bronze Age Collapse (ca. 1200 BCE) or the early Iron Age. Wikipedia at https://en.wikipedia.org/wiki/Armenians#Origin recounts some of the key points:
"While the Armenian language is classified as an Indo-European language, its placement within the broader Indo-European language family is a matter of debate. Until fairly recently, scholars believed Armenian to be most closely related to Greek and Ancient Macedonian. Eric P. Hamp placed Armenian in the Pontic Indo-European (also called Graeco-Armenian or Helleno-Armenian) subgroup of Indo-European languages in his 2012 Indo-European family tree. There are two possible explanations, not mutually exclusive, for a common origin of the Armenian and Greek languages. . . .
Ancient Greek historian Herodotus (writing circa 440 BCE), suggested that the Phrygians of western Anatolia, who spoke a poorly-attested Indo-European language, had contributed to the ethnogenesis of the Armenians: "the Armenians were equipped like Phrygians, being Phrygian colonists" (7.73) (Ἀρμένιοι δὲ κατά περ Φρύγες ἐσεσάχατο, ἐόντες Φρυγῶν ἄποικοι.). This appears to imply that some Phrygians migrated eastward to Armenia following the destruction of Phrygia by a Cimmerian invasion in the late 7th century BCE. Greek scholars also believed that the Phrygians had originated in the Balkans, in an area adjoining Macedonia, from where they had emigrated to Anatolia many centuries earlier. However, the theory that Armenians (or their language) originated in the Balkans, which was once widely accepted, has been facing increased scrutiny in recent years due to discrepancies in the timeline and lack of genetic and archeological evidence. The view that Armenians are native to the South Caucasus is supported by ancient Armenian historical accounts and legends, which place the Ararat Plain as the cradle of Armenian culture, as well as modern genetic research. In fact, some scholars have suggested that the Phrygians and/or the apparently related Mushki people were originally from Armenia and moved westward.
Most researchers now believe that the Armenian language is as close to Indo-Iranian languages as it is to Greek. . . . Genetic studies explain Armenian diversity by several mixtures of Eurasian populations that occurred between 3000 and 2000 BCE. But genetic signals of population mixture cease after 1200 BCE when Bronze Age civilizations in the Eastern Mediterranean world suddenly and violently collapsed. . . . In the Bronze Age, several states flourished in the area of Greater Armenia, including the Hittite Empire (at the height of its power in the 14th century BCE), (Mitanni (South-Western historical Armenia, 1500-1300 BCE), and Hayasa-Azzi (1500–1200 BCE). Soon after Hayasa-Azzi came Arme-Shupria (1300s–1190 BCE), the Nairi Confederation (1200–900 BCE), and the Kingdom of Urartu (860–590 BCE), who successively established their sovereignty over the Armenian Highland. Each of the aforementioned nations and tribes participated in the ethnogenesis of the Armenian people. Under Ashurbanipal (669–627 BCE), the Assyrian empire reached the Caucasus Mountains (modern Armenia, Georgia and Azerbaijan)"
