There's a new massive study on Prehistoric Europe and Anatolian samples, I'll comment on it later in other thread.

But the first thing that struck me while reading it was this
You can see that there are 3 Aegean Basin samples(in purple), 2 of them show a strong affinity with the modern Greek/Albanian and Cretan populations.
First, there's this big cluster of Early European Farmers(EEF) that seem to cluster just with themselves and with Sardinians to some extent.
And then there are this 2 samples, with other 1, the only few among many samples that resemble modern peoples.
But if you look to the right, you can see that there it says that those samples are very HOMOZYGOSITIC.
This people have a very low genetic diversity, and yet they resemble modern populations the most.
The thing is that modern European populations are a 3-way admixture, Greeks are overwhelmingly EEF but still...
As it is obvious this relatedness to a modern ethnicity/people doesn't stem from admixture with Yamnaya incomers...
The only explanation we're left with, is that these SAMPLES were PART of TRIBES that are the GENESIS of the bulk of MODERN ANCESTRY, or at least closely related.
And that these 'tribes' 'suffered' from an intense genetic drift and lack of efective genetic diversity, comparatively with European Hunter-gatherers... (which is crazy)
Think about it, this ""inbred"" populations are the closest to modern Greeks.
This strongly suggests that EEF ancestry is also the product of a few ancestors with high reproductive success.
