The creek is clearly doing what creeks do all the time.
Trying to make Arbereshe something distinct from Albanians, of course is nothing new in his country.
He doesn't understand that having less J2b doesn't mean that this population wasn't Albanians but that they probably descended from South Albania where even today there is lot less J2b than North Albania but that doesn't make the less Albanian but simply reflects the Tosk-Gheg difference.
I dont need to do anything the numbers speaks for themselves. South Albanians are mixed too. A mixture of Gheg muslims that settled on the region post 1500 AD , with local Greek and Arvanites.
Ottomans settled gheg gangs all over the place.Even in Greece. If Kolokotronis, the warlord father of the leader of the Greek revolution, hadnt made a 30 feet pyramid with heads of the 20 000 Turkoalbanian thugs that the Turks settled in Peloponese to spread Islam and control the region, today their descendants would have been too in the hundreds of thousands. That said their Genetics wouldnt have been identical with the genetics of North Albania, but something in between those and those of local Peloponneseans. The Turkish census of 1897 reports that the Vilayet of Iskorda , which corresponds to modern day North Albania, had a population bellow 100 000.Catholics were under-counted ,and were probably the majority of the population of Vilayet,but today they are 20%(if you correct for immigration since 1991). Similar demographic upsetting occurred in South Albania, then wholly part of the Vilayet of Yanya, where Gheg muslim colonists, descending from Ottoman garrisons and military units,slowly demographically overwhelmed local Albanian and Greek Orthodox. The population then of South Albania was little more than 300 000, and most were Christians.Today Christians are 25%(if that ) Thus the genetic profiles of the regions adapted accordingly to the different growth rates of the different religious communities that had different origins. Autosomally might be more similar, but the Y-dna differences still linger. Until there is a comparison between the Y-dna of the Muslims of South Albania (that have heavy ancestry from Gheg colonists and muhajirs from the Balkan wars) with the Christians of region, you cant speak of South Albanian profile, as it has been distorted in the last 2-3 centuries from the higher demographic growth of Muslim colonists.
It's probably really hard to get over the fact that these people's language wasn't creek but nevewrtheless we still gonna claim them and pretend they were something different than Albanians
Or it could be the other way around. Arbereshe might be Albanian in origins,as their genetic profile corresponds to that of the other Balkan nations, but the genetic and linguistic evidence suggest that Gheg Albanians:
a) Could have recent origins, as recent as the middle ages, from outside of the region as there is no genetic continuity with any of the near by populations.
b) Their language/dialect wasn't native to North Albania, but transplanted there,as it is substantially different from Arbereshe which was spoken in the same region today inhabited by Ghegs. It also has no Greek influences, in-spite being in the proximity of Byzantine strongholds,and in the Greek linguistic zone of influence.
c) they cant have recent common origins with Arbereshe, as they are genetically very different from Arbereshe.
What ever small genetic similarities they might have, are probably are due to incorporating Arbereshes remnants into the Gheg tribes that resettled in the region.
But instead of looking in Arbereshe's dna the creek should explain how all the ancient Greek dna till now come up to be J2a while in Epirus and Peloponnese today E-V13 is dominant?
E-v13 is less than 30% in Peloponnese. J2a is as high as in the rest of the Greek Regions(very low in Ghegs), while J2b is the lowest in Greece(1/8th than that of ghegs). G2a is at similar rates as in the rest of Greece(also near absent in Ghegs).
So..
