Well there was one E-M78* in a Gheg from Arberesh study who was V13-, V22-, V12- so likely some L618*.
I think E-V13 spread about 8000 years ago via maritime route to Southern Italy and from there to Dalmatia as part of Cardial Impresso culture. Genetically mostly same as other Anatolian EEF's with the small Natufian-like influence and also these weren't much of farmers to begin with, more of fisherman population which adopted farming later. V13 developed on Dalmatian coast as part of subsequently Danilo, Hvar and few other cultures. When IE pastoralists came V13 adapted well unlike most EEF's. May be that being Afroasiatic pastoralists in distant origin, Phalic cult being likely present in Neolithic Dalmatia unlike other G2a EEF's where Matriarchy was the norm. Archaeologists spoke of this potential indication of some Patriarchy in Neolithic Dalmatia which was unusual, but as we now know genetically these were a different people (not G2a2).
Likely source of V13 is Pre Pottery Neolithic B, there is one Middle-eastern clade of L618, found in a Saudi, and an Algerian who clusters with him.
So with an influence of some R1a and R-Z2103 they formed Cetina culture, and they flourished at that time. At the same time Bell Beaker IE groups were also penetrating from NW bringing more J-L283, Cetina people migrated to Greece (some PH1246 there), but also towards the East forming the Bubanj Hum III, Armenochori, Belotic-Bela Crkva complex. These should have been the E-CTS1273, then they became part of a large Danubian archaeological complex in cultures such as Vatin, Verbicioara etc. spreading towards Carpathians. Cetina died out in the West with the remnants joining J-L283 dominated cultures.
At this stage the languages brought by J-L283 might have been Veneto-Liburnian while in the East some other language related to Greek was spoken, like Paeonian, Phrygian. Albanian itself has some distant connections to Greek itself. Possibly Dorian was spoken by some cultures which included some V13 clades such as Y3183 and L241. So it seems some older Z2103 languages were prominent.
But if L283 brought classical Illyrian, maybe that originally Cetina people (so V13) spoke Veneto-Liburnian.
One of peoples are also the Pelastians, Strymon rivers former name was Palaistinos, and some R-Z2103 clades such as Y5586 are very divrse in the area as are some CTS1273 and especially E-FGC44169 which is very diverse in the Middle East, and at least some of these might be Philistines (one was R-M269). "Pelasgian" is likely a Greek corruption (which designated different peoples), but as attested by Egyptian P'R'S'T, Philistines and river Palaistinos this must be the original name of this people that spoke some IE language. Though as seen by most Greek Philistine burial the European component was mostly Anatolian EEF. So already in Bronze age formed this Balkan mixture of EEF + some Yamnaya, with those Delmatae being in cluster not with modern Albanians but with modern Catalans etc.
Then the late Bronze Age collapse came. From Central Europe a wave of Urnfield R-U152 heavy peoples invaded including proto-Illyrians. Meanwhile from the East appeared Noua culture a Srubnaya variant which might have brought the Thracian language, and being R-Z93 + R-Z92.
Urnfield Illyrians and other Urnfield peoples overwhelmed the Western Balkan, they pushed some V13 clades like L241, and Y3183 to the East all the way to Greece which likely included Dorians, others being assimilated. In the Central Balkans some E-V13's were pushed to the South (hence some diversity in the South of Albania) where they might have formed the subsequent Southern Illyrian Tumulus culture. Along the way some R-U152 became Dorian increasing Central European autosomal profile such as the one seen in Cretan sample.
Some V13 clades such as CTS9320 which originate in Eastern Balkans (maybe Carpathians) likely backstabbed the others and spread the new Thracian language around. :grin:
I think linguistic picture of the Balkan might have changed dramatically in Bronze Age collapse.
This is of course with Thracian being newer arrival, which I think is quite likely, might be same with the Illyrian.
