New ancient DNA from Greece, specifically from the Corinth region and western Greece. The older samples are similar to other samples from Greece and the Balkans, but the Roman-era samples show a shift toward Anatolia, somewhat consistent with Roman imperial events.
One of the Roman-era Corinthians has Y-DNA R1b-L584, consistent with this eastern shift. Another individual from the Roman era had J2-M92, plausibly reflecting Anatolian affiliation as well. Other Y-DNA haplogroups found at these sites are typical of the Balkans: E1b-L618, R1b-PF7562, J2b-L283, T1a2, and G2.
==========
The consensus of our findings (PCA, ADMIXTURE, and qpAdm using the “Most_Proximate” set of sources) shows that the Amvrakia and Tenea individuals can be considered descendants of the LBA and IA populations of the southern Balkans, especially the area of present-day Greece. In addition, the Roman Tenea individuals appear to have an additional minor contribution from the east, represented by BA Levant and Hellenistic Türkiye (Northwest and West, including Halikarnassos) in the “Most_Proximate” qpAdm analysis. Overall, local genetic continuity is suggested from LBA/IA Greece to Archaic, Classical, and Hellenistic Greece, and to a lesser degree to Roman Greece. However, for the latter, the spatial sampling is inadequate to justify such a generalization.
