Okay so now either or. Either this proves there is genetic continuity between Greeks and Myceneans and Minoans. Or it is just an overlap of Anatolian_N and CHG. Can not really have it both ways.
Knowing the Y DNA of my Maternal Grandfather was found in Heraklion Crete 4.9-3.9 kya, I have my own opinions. But lets be honest here. Some things are mutually exclusive.
I would go on a rant that it is hard to just find pure bred (100%) Anatolian_N and CHG and just somehow go through the generational permutations to create a false positive, false positives mind you for populations that are historically known to have had population movements as well as trade connections. That's a rabbit hole I am not willing to go down on.
Alas. there are three populations in South Italy, two around Palermo, one gulf of Taranto. Two of them have more affinity with these ancient populations than North Italians.
Nevertheless, I am not here to defend these guys
I am sure peer reviewers did that.
