Abstract

In recent years, the study of the ancient human genomes has gained exceptional interest and unsolved questions related to the origin and admixture of populations can now be answered. In Greece, prehistoric human samples that had been analyzed for ancient DNA are mainly originated from the Stone and the Bronze Age. Based on those samples, evidence has emerged that indicates genetic differentiation between the Neolithic era and the Bronze Age. However, a recent study involving only one excavation site showed that individuals from Greece during the Early Bronze Age tended to show more genetic similarities to individuals, which are dated to the Neolithic period of Greece and Western and Central Anatolia rather than to individuals from the Middle and Late Bronze Age of Greece. Due to the small number of sampling sites, the above hypothesis has not been tested, yet. The aim of this thesis is the independent verification of the above hypothesis using genetic data from samples from the cave ossuary of Lake Vouliagmeni in Perachora, Corinthia, which based on archaeological estimates, are dated to the Early Bronze Age (~2,700-2,200 Before Common Era, BCE). The excavation findings consist of six petrous bones and four teeth. An analysis of ancient DNA was carried out and the ancestry of the Perachora individuals and their relationships with populations of neighboring regions of the same era were examined. According to the results of these analyses, Perachora individuals show more genetic similarities to Neolithic individuals than to those of Middle and Late Bronze Age, thus strengthening the prevailing hypothesis regarding the genetic composition of Early Bronze Age individuals in Greece. Finally, the results show genetic differentiation between the Early and later Bronze Age phases in Greece, due to the arrival of an ancestry genetic component from the Steppes, , during the Middle Bronze Age.
