My point was that it might have been native to Greece but it wasn't native to the Peloponnese at the beginning
but to more Northern parts of Greece Thessaly,Epiros and arrived from there to the Peloponnese.
Just one possibility
Another thing which might be interesting is that there exists a specific EV13 clade in the Cyclades which is found only there as it seems.
I am sceptic about the one in Cyclades. It could be a recent mutation. It may be that our sample size is very small. It could be a certain colonisation of the islands before the Mycenaean period. Sample sizes make conclusions with that accuracy problematic
