A genetic probe into the ancient and medieval history of Southern Europe and West Asia

Abstract

Literary and archaeological sources have preserved a rich history of Southern Europe and West Asia since the Bronze Age that can be complemented by genetics. Mycenaean period elites in Greece did not differ from the general population and included both people with some steppe ancestry and others, like the Griffin Warrior, without it. Similarly, people in the central area of the Urartian Kingdom around Lake Van lacked the steppe ancestry characteristic of the kingdom's northern provinces. Anatolia exhibited extraordinary continuity down to the Roman and Byzantine periods, with its people serving as the demographic core of much of the Roman Empire, including the city of Rome itself. During medieval times, migrations associated with Slavic and Turkic speakers profoundly affected the region.

Figures

Fig. 1:
Fig. 1:. Genetic heterogeneity in the Aegean.
(A) A map of Aegean sites. (B) Timeline of Aegean individuals, with vertical jitter added to distinguish contemporaneous individuals. Ancestry changes of five components (C-G) show an increase of Caucasus hunter-gatherer (CHG) and Eastern European hunter-gatherer (EHG) ancestry over time and a dilution of Anatolian Neolithic ancestry. During the Minoan and Mycenaean periods of the Bronze Age (H) Eastern European hunter-gatherer ancestry was variable, absent in Minoan individuals of Crete and present in most, but not all Mycenaean individuals of the mainland.
Fig. 2:
Fig. 2:. The Kingdom of Urartu and its neighbors.
Panels (A-D) show comparisons of ancestry in four ancestral components (SRB_Iron_Gates_HG, the 5th component of the model of (1) is negligible). This analysis shows a stark contrast between Armenia and the other populations in terms of Eastern European hunter-gatherer ancestry (B), and between Van and Assyrian Mesopotamia in terms of Levantine ancestry (C). When unlabeled individuals are ordered in increasing Eastern European hunter-gatherer ancestry, Assyrian Mesopotamia, Van lack this ancestry (except an outlier individual from Van), while individuals from Armenia mostly possess it, and those from Hasanlu have a limited range from zero Eastern European hunter-gatherer ancestry to a maximum level that is less than that seen in Armenia.
Fig. 3:
Fig. 3:. The Roman Empire East and West.
(A) The Imperial period Romans from the vicinity of the city of Rome in Central Italy resembled Roman/Byzantine Anatolians in their average admixture proportions (95% confidence interval (C.I.) of ±1.96 standard errors shown as boxes and a heteroskedastic Gaussian process is fitted to unlabeled Italian and Anatolian individuals; dashed lines indicate 5% and 95% quantiles). (B) P-values of the Baringhaus-Franz multivariate two-sample test(47) for pairs of populations indicate that Imperial Romans can be drawn from the same distribution as Roman/Byzantine ones (p=0.19), but are significantly different (p≤2.16e-03) from all other periods of Italy. (C) Hierarchical clustering of raw ancestry estimates of diverse individuals shows overlapping distributions of Imperial Roman and Anatolian Roman/Byzantine individuals (black) without knowledge of their ancestry labels and differentiated from the distributions of SE Europe, Armenia, and the Levant.
Fig. 4:
Fig. 4:. Central Asian Turkic admixture in Anatolia.
(A) Individuals from Çapalıbağ (1300-1650CE) and present-day Turkish individuals are intermediate between Byzantine Anatolia and 500-1500CE Central Asians along a global principal components analysis distinguishing West from East Eurasians (left-to-right on the horizontal dimension; noise added on the vertical dimension to distinguish points). (B) 2-way unsupervised ADMIXTURE analysis of “eastern” ancestry: Byzantine: (0%), present-day Turkish (9%), Çapalıbağ (18%), Central Asian individuals differ between 100% (in Mongolia) to 43% (some ancient populations of Kazakhstan and Kyrgyzstan). (C) Individuals from Çapalıbağ in Turkey admixed 12.2±1.4 generations (342±39 years) prior to their time using Byzantine Anatolians and Central Asians (from 500-1500CE) as sources. (D) Present-day Turkish people genotyped on the Human Origins array (35) admixed 30.6±1.9 generations ago (857±53 years) using the same sources as in (D).
Fig. 5:
Fig. 5:. Byzantine and Medieval Southeastern Europe.
We sort admixture proportions of Anatolian Neolithic ancestry to investigate the dilution of this ancestry in present-day populations from Southeastern Europe. Roman/Medieval/Byzantine-era individuals are indicated in bold. During the Bronze Age the range of this ancestry was immense as observed in (1), but present-day people from the Balkans have less of this ancestry than was the case from the Bronze Age through the Iron Age and down to the classical antiquity (Ancient). Medieval/Byzantine people from the Balkans were diverse, with some (right) continuing the ancient pattern of high Anatolian Neolithic ancestry, several (middle) overlapping with the range of present-day people, and some (left) having as little such ancestry as present-day Balto-Slavic people from Eastern Europe.
Fig. 6:
Fig. 6:. Pigmentation in West Eurasia.
We show the temporal distribution of genetically predicted Eye (A), Skin (B), and Hair (C) color in West Eurasians of the last 16,000 years; each point represents an individual, with the top row for each subphenotype corresponding to Southern Arc and the bottom row corresponding to northern, central and western Europeans and people of the Eurasian steppe. Panel (D) shows composite phenotypes of all three aspects of pigmentation using the same color scheme as A-C and denoted as eye color (circle), hair color (top), and skin color (bottom) in the composite phenotype symbols. The modal phenotype of West Eurasians had brown eyes, intermediate skin pigmentation, and brown hair, with the highest prevalence (Fisher’s exact test) of low pigmentation outside the Southern Arc (in the rest of Europe and the Eurasian steppe).
