"Armenians as Phrygian colonists, or, rolloff analysis of Armenians as a mixture of Sardinians+Balochi
I analyze the Yunusbayev et al. Armenians_Y sample in a similar manner as the South Indian Brahmins. The 30 lowest f3 statistics are:
I carried out rolloff analysis using the Balochi and Sardinians as references, for a total of 510,844 SNPs. Note that the Burusho were not used in this experiment, because they were culled due to more than 5% East Eurasian admixture, as per the followed procedure.
The Balochi are very similar to the Burusho otherwise, and this also gives me the opportunity to see a Sardinian+Balochi population pair to complement a previous analysis of French as Sardinian+Burusho, which presented an f3 signal of quite similar intensity. The exponential fit is seen below.
The jackknife gives an age estimate of 113.194 +/- 14.674 generations, or 3,280 +/- 430 years, assuming a generation length of 29 years.
I had somewhat expected the Armenians to show a more recent signal of admixture than the French, as they lived much closer to the boundary of Europe and Asia, and may have had more opportunity to admix between Sardinian-like populations of Europe and "West Asian"-like populations of Asia.
But, the inferred date also raises another possibility. Herodotus says of the Armenians who were part of the army of King Xerxes:
the Armenians were equipped like Phrygians, being Phrygian colonists" (7.73)
Now, the Phrygians became masters of Central Anatolia during the tumultuous events near the end of the Bronze Age (12th century BC), following the collapse of the Hittite Empire. And, their ancestral homeland was in Thrace. And, there is fairly good evidence that Armenian is the closest language related to Greek within the Indo-European language family. And, we have some tantalising evidence that even during the Iron Age, the population of Thrace was Sardinian-like. And, the Armenians do contrast with their Caucasian neighbors in possessing ~10% of the Sardinian-like Atlantic_Med component that South and Northeast Caucasians lack.
All of the above combine to make a pretty compelling story. Could it be that Armenians preserve a legacy of admixture between a linguistically Indo-European speaking, genetically Sardinian-like population, which arrived in Asia Minor from the Balkans at the end of the Bronze Age, finally settling in the Armenian Highlands, and mixing with the local people they encountered?
The plot thickens. And, this is, certainly, a question that can be answered by ancient DNA research, e.g., by comparing the genomes of historical Phrygians and Armenians with those from Hittite-era, or earlier Anatolians".
