The mtDNA genetic relationships between Thracians and the other ancient Eurasian populations (Supplementary TableS2) were directly explored through a correspondence analysis (COA, Fig.3). The first component, which accounted for 28.3% of the total variance, clearly separates all hunter-gatherers from the rest of Neolithic, Bronze Age and Iron-Age population groups. Along the second component (10,6% of variance), the ancient populations appear instead distributed along a cline of genetic variation which extends from the Early Neolithic farmers of Southern Europe and Anatolia to the Late Neolithic/Bronze Age Europeans and Steppe pastoralists, in accordance with the genomic structure of ancient Europe29,30,32,33. From an autosomal genetic perspective, besides showing the clear discontinuity of Paleolithic hunter-gatherers, recent genome-wide aDNA studies, have indeed outlined two opposite genetic components contributing to the European genetic ancestry: i.e the ancestry of the Early European farmers related to Anatolian farmers and pre-farming Levant populations and, on the other side, the so-called Steppe ancestry eventually spread into Europe and Asia during the Bronze Age migrations of Yamnaya herders. In this scenario, the mtDNA genetic composition of analyzed Thracian population located them in the middle of this cline, clustering closely to the Peloponnese-Neolithic individu-als (Peloponnese_N) and the Chalcolithic and Bronze Age populations of the Balkans (Balkans_Chalcolithic, Balkans_BA). This finding seems to support a mitochondrial genetic profile of the Thracians that reflects their geographical position at the gateway of Europe. In a more general perspective, Thracians show a mtDNA genetic composition that is thus intermediate between the western Eurasian and the Mediterranean populations, docu-menting a prolonged interaction between people of these regions during the Bronze Age. On the other hand, the relatively higher distance with the Bronze Age populations from the Steppe (Steppe_EMBA and Steppe_MLBA), may support the hypothesis that the Thracians largely derived from local people9–11 with only a low percentage of the gene flow from the Steppe, at least during the early stages of their cultural development. However, in order to better explore this hypothesis, it is worth emphasizing that the perspective offered here by the analysis of mito-chondrial genomes should be integrated by the possibility of testing the results obtained with Y-chromosome and autosomal genome-wide data. At this respect, several studies have indeed pointed out the sex-biased nature of the recent demographic changes and expansions in Eurasia39–43, thus suggesting possible sex-specific patterns of migration.

Several studies demonstrated that Balkan Peninsula has been in different times a crossroad for people moving from and to Europe and beyond16,44. While previous analyses of modern populations demonstrated the impact of such migrations on the genetic makeup of present-day Bulgarians14–16, scarce information were available for the ancient (proto-) Bulgarian maternal gene pool and were mainly limited to HVS1 data from the medieval period19. In this study, we provide, for the frst time, genetic details of an ancient population, which is particu-larly relevant from both a chronological and a geographical point of view. In accordance with their geographical location, Thracians show a genetic composition clearly intermediate between East Europe and Mediterranean, that suggests multiple admixture events and population movements occurred across what is now the modern day Bulgaria. Albeit limited to DNA transmitted along the female lines of descent, our genetic data on ancient Thracians provide a direct evidence of how the Balkan region has been a link between East and West Europe since the prehistoric time, and particularly during the Neolithic and post-Neolithic events. In this perspective, future studies will certainly benefit from the analysis of nuclear genome (Y-chromosome and autosomal genetic varia-tion) in order to integrate the observed mtDNA genetic patterns within a more comprehensive overview and for testing the possibility of different sex-biased migrations in the area.Overall, the ancient mtDNA data presented in this study integrate the existing database and has important implication for understanding the origins of the peopling in this part of Europe and for enlarging the knowledge on the ancient Bronze Age civilizations. How and to what extent ancient Thracian people has contributed to the present-day Bulgarian gene pool remain largely unknown due to the lack of large mitogenomes from contempo-rary populations from the area, necessary for a phylogenetically and demographically informative comparison. https://www.researchgate.net/publication/332131593_Ancient_human_mitochondrial_genomes_from_Bronze_Age_Bulgaria_new_insights_into_the_genetic_history_of_Thracians?fbclid=IwAR1UJXue2ZqoCEH7vhbVBY6zct-ynJ5WWmB3hQBPsVmqznzz3j9zDgdmEnA
