The Diversity of Greece

Greece is a country that is incredibly diverse. When You go up into the northern regions of the country, towards Thessaloniki, people typically have higher levels of paleo Balkan and Balto Slavic related DNA. When you go down towards the south towards the Dodecanese, people typically have higher levels of both Anatolian and Levantine related admixture.

The Greek Genome

The Greek people have a unique genetic makeup that can be underpinned by three ancestral Bronze Age migrations. In this article, we will look at the Greek genome through a variety of different time periods to understand who these people are from a genetic perspective.

Stone Age DNA Breakdown

An interesting breakdown of the average Greek genome shows that around 60 percent of their DNA is Anatolian Neolithic farmer related. The Anatolian Neolithic farmers were one of the first people to discover agriculture, and they migrated into Greece well over 9,000 years ago. These Anatolian Neolithic farmers mostly belong to the haplogroup G2a, which today is found in high frequencies in Sardinia. As a matter of fact, the Sardinians are over 82 percent Anatolian Neolithic derived and serve as the best representation for these ancient people.

If we take a look at this breakdown one more time, we see that around 23 percent of their DNA is Caucaso-Iranian related. During the Bronze Age, there was a migration of Eastern Anatolians. These Eastern Anatolians belong to haploid group J2. It would be the infusion of these G2a and J2a people, which would lay the foundations of the Minoan civilization.

Bronze Age Migrations

Compared to the ancient Greeks, the modern Greek has more European DNA. Ancient Greeks had components of European DNA because of the Indo-European migrations as well as this inherent paleo Balkan source. But because of the Slavic migrations of 600 A.D, the Greek genome was impacted.

The Minoan Civilization

The Minoan civilization was a Bronze Age civilization that arose on the island of Crete and other Aegean islands. The Minoans were a seafaring people who engaged in extensive trade with the Levant and Egypt. They were also known for their art, architecture, and writing system.

Indo-European Migrations

The Indo-European migrations were a series of migrations that occurred between 4000 and 1000 BCE. These migrations brought the Indo-European language family to Europe and Asia. The Greeks were one of the Indo-European groups that migrated to Europe.

Slavic Migrations

The Slavic migrations were a series of migrations that occurred between the 5th and 10th centuries AD. These migrations brought the Slavic language family to Eastern Europe and the Balkans. The Slavs settled in Greece and had a significant impact on the Greek genome.

Iron Age DNA Breakdown

An Iron Age DNA breakdown of a Greek person from Thessaloniki shows that the majority of their DNA is derived from this Anatolian energy and source. But they've got around 20 percent paleo Balkan Illyro-Thracian related DNA as well as around 20 percent Slavic DNA as well.

Modern Greek Populations

The modern Greek populations most similar to the ancient Greeks are actually the Dodecanese and the Cypriot Greeks. As we can see from this genetic breakdown, the Dodecanese have around 77 percent of their DNA from this Anatolian Aegean source. But additionally, they've got Levantine related DNA which comes from contacts Greek people have had with Levantine related groups like the Phoenicians.

Greek Identity

For the most part, the Greek identity is encapsulated by this Aegean and Anatolian Core overlaid with a European genetic input. Obviously, there's a lot more complexity to this because I've had to summarize all the information for you.

Personalized DNA Analysis

If you've got an existing DNA test like 23andMe ancestral DNA my heritage and you're interested in having your own personalized DNA reading, I offer comprehensive DNA analysis where I can tell you all the ancient civilizations you're related to.

Conclusion

In conclusion, the Greek genome is a unique and complex mixture of different ancestral migrations. From the Anatolian Neolithic farmers to the Indo-European migrations and the Slavic migrations, the Greek people have a rich genetic history that is still being uncovered today.
