There’s been many discussions about who the Greeks are/are not, where they came from, and – most importantly – what’s their racial make-up.
I think I put together a comprehensive data-set to establish their ethnic history, which will make it possible to answer a lot of questions.
First - their history.
In the PCA image their evolution is clear. The first people populating Greece were the Neolithic peoples who populated the Mediterranean area in that time.
Then they shifted towards the Levant and Anatolia, which is seen by the Minoans.
Then the Mycenaean period came, and so did the northern Europeans – it’s the first time we see a shift towards the north (and the first time any northern admixture appears, which will be shown in the next pic).
From now on, that shift will continue, until the Classical Era, where I used the best 2 samples I could find, from northern Macedonia.
Now we see the Near Eastern gene flow again (mostly in the southern islands), and the Slavic gene flow, which makes modern Greece sit somewhat inbetween the Near East, the Balkans and Classical Greeks.
