“…Other putative recipient population samples from northern and central Italy were made available (N = 201; Brisighelli et al 12 ). In addition, DNA samples from Albania, 22 Croatia 23 and West Anatolia 24 were obtained as reference populations. To analyse samples of source, recipient and reference populations of comparable size, Italian populations were clustered into six main groups following geographical and historical criteria (Supplementary Table S1).…”

Greek colonisation of South Italy and Sicily (Magna Graecia) was a defining event in European cultural history, although the demographic processes and genetic impacts involved have not been systematically investigated. Here, we combine highresolution surveys of the variability at the uni-parentally inherited Y chromosome and mitochondrial DNA in selected samples of putative source and recipient populations with forward-in-time simulations of alternative demographic models to detect signatures of that impact. Using a subset of haplotypes chosen to represent historical sources, we recover a clear signature of Greek ancestry in East Sicily compatible with the settlement from Euboea during the Archaic Period (eighth to fifth century BCE). We inferred moderate sex-bias in the numbers of individuals involved in the colonisation: a few thousand breeding men and a few hundred breeding women were the estimated number of migrants. Last, we demonstrate that studies aimed at quantifying Hellenic genetic flow by the proportion of specific lineages surviving in present-day populations may be misleading.

Shared language, diverging genetic histories: high-resolution analysis of Y-chromosome variability in Calabrian and Sicilian Arbereshe

The relationship between genetic and linguistic diversification in human populations has been often explored to interpret some specific issues in human history. The Albanian-speaking minorities of Sicily and Southern Italy (Arbereshe) constitute an important portion of the ethnolinguistic variability of Italy. Their linguistic isolation from neighboring Italian populations and their documented migration history, make such minorities particularly effective for investigating the interplay between cultural, geographic and historical factors. Nevertheless, the extent of Arbereshe genetic relationships with the Balkan homeland and the Italian recipient populations has been only partially investigated. In the present study we address the genetic history of Arbereshe people by combining highly resolved analyses of Y-chromosome lineages and extensive computer simulations. A large set of slow- and fast-evolving molecular markers was typed in different Arbereshe communities from Sicily and Southern Italy (Calabria), as well as in both the putative Balkan source and Italian sink populations. Our results revealed that the considered Arbereshe groups, despite speaking closely related languages and sharing common cultural features, actually experienced diverging genetic histories. The estimated proportions of genetic admixture confirm the tight relationship of Calabrian Arbereshe with modern Albanian populations, in accordance with linguistic hypotheses. On the other hand, population stratification and/or an increased permeability of linguistic and geographic barriers may be hypothesized for Sicilian groups, to account for their partial similarity with Greek populations and their higher levels of local admixture. These processes ultimately resulted in the differential acquisition or preservation of specific paternal lineages by the present-day Arbereshe communities.

“…41,42 Parental groups were assembled as specified in Table 1 for mtDNA and in Supplementary Table 2 for the Y-chromosome. 1,14,18,[43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60] To gauge significant deviations from neutral theory, 61 the Ewens-Watterson homozygosity test 62,63 was performed on Iranian mtDNA control region sequences (nucleotide positions 16 019-16 569). In addition, mtDNA control region sequence diversity was evaluated by nucleotide diversity index.…”

Mitochondrial DNA and Y-chromosomal stratification in Iran: relationship between Iran and the Arabian Peninsula

et al. 2011

Modern day Iran is strategically located in the tri-continental corridor uniting Africa, Europe and Asia. Several ethnic groups belonging to distinct religions, speaking different languages and claiming divergent ancestries inhabit the region, generating a potentially diverse genetic reservoir. In addition, past pre-historical and historical events such as the out-of-Africa migrations, the Neolithic expansion from the Fertile Crescent, the Indo-Aryan treks from the Central Asian steppes, the westward Mongol expansions and the Muslim invasions may have chiseled their genetic fingerprints within the genealogical substrata of the Persians. On the other hand, the Iranian perimeter is bounded by the Zagros and Albrez mountain ranges, and the Dasht-e Kavir and Dash-e Lut deserts, which may have restricted gene flow from neighboring regions. By utilizing high-resolution mitochondrial DNA (mtDNA) markers and reanalyzing our previously published Y-chromosomal data, we have found a previously unexplored, genetic connection between Iranian populations and the Arabian Peninsula, likely the result of both ancient and recent gene flow. Furthermore, the regional distribution of mtDNA haplogroups J, I, U2 and U7 also provides evidence of barriers to gene flow posed by the two major Iranian deserts and the Zagros mountain range.
