To continue the discussion,since it seems people are not posting here to follow the idea I have started to tell:
On genetics,I think is pretty clear that ancient Thracians and Illyrians were J2 clades bearers,besides other HGs.
Now,if you take Albania Y DNA lines,you can see that J2 is quite significant.
To tell that J2 is from Ancient Greeks,I think is an over-simplifcation.
I think most of that J2 is from Thraco-Ilyrians and was brought by them,in Albania.
There is also about 9% R1A,but according to some Albanian I have talked with,Tosks are having about 15% R1A1.
So I think most of this is still from Thracians and Ilyrians.
As for E-V13 I think was in Albania before Thracians and Ilyrians came and that population was conquered and assimilated by Thraco-Ilyrians.
You can notice from the wars that Burebista went against Celts,that were living in Balkans between Ilyrians,that is not said that Burebista and Dacians attacked Illyrians.
So I think this is a proof that Thracians and Illyrians were populations very closed and their languages had a high degree of mutual inteligibility.
If you take what words are known from Thracian,are cognates from them with Albanian.
Even if some people will dislike what I will tell,I think Iranians/Persians,old Iranians/Persians,were quite closed to Thracians and Illyrians.
You can still notice some resemblances between folk costumes and music from North Iran and folk costumes and music from Romania,Albania and South Slavic countries.
Sure,now Arabs conquered Iran so the people there are very mixed with Arabs,they do not look anymore as ancient Persians were looking like.
As for Balto-Slavs,I think they were closed people to Thracians and Illyrians since are no recorded wars between Thracians and Illyrians on one side and Balto-Slavs on another side.
And when Slavs came and settled in Balkans (with large numbers of them settling in Dacia/Romania and switching to Dacian/Romanian ethnicity,since lots of genetics in Romanians is of Slavic origins) Dacians did not fought with them,but became allied and is known that it existed a South-Romanian-Bulgarian Empire.
There is also the fact that on K36,Russians and Ukrainians I saw are scoring 8-11% Balkanic admixture,so this means that it was either a conquest from Thracians and Illyrians of Balto-Slavs,but this is not recorded anywhere in history,or that these people lived together and mixed between them,for a long time.
I also saw the results of 2 people from Baltic countries (Latvians/Lithuanians,not Estonians) and both were having 5-6% Balkanic admixture,which supports what is wrote above.
So I think the problem of whom are descendants of Thraco-Illyrians is more complex,that telling that just a people is descendant of Illyrians and also,that are no pure descendants of Thraco-Illyrians.
Facts say that Illyrian language has no link with today's Albanian.
And Albanian linguists know, but it is less clear why there is a need of writing about continuity Illyrian and Albanian language, if only for debates it can be possible to debate about anything but we must have facts and strongholds.
Facts:
1. Illyrian ic CENTUM, Albanian is SATEM, and it is enough, but we give more.
2. Albanian first document was in 15 century (Paulus Angelus, 1462), Illyrian language was long gone before (millennium and two hundred years or more)
3. Albanian language has the most Balto Slavic words, for example Professor Gustav Mayer claimed that Albanian is brother of Latvian language, it can be linked probably because Albanian has borrowed much from Dacian, and Dacian was one of variant of the Thracian.
4. Albanian is the closest to Balto Slavic and Armenian (for Armenian there is link because about 15% Albanians have Armenian haplotype R1b ht35)
5. Albanian borrowed about 600 words of Latin
6. Albanian borrowed 1.100 words from Turkish, also Albanian has words from Afro-Asiatic languages
7. Only 30 words in Albanian can be brought to the Illyrian (about 1.000 Illyrian words is known), and it can be borrowed from other Balkan people who had closer link with Illyrian.
Due similarity Albanian with Dacian and Balto Slavic languages a lot of scientists think that original place ancestors of today's Albanian is somewhere in Romania (maybe it can be Bessarabia too, or some space in that region).
Geg Albanian haplogroups (today's) show that region ought to have very strong E-V13 and moderate J2, R1b ht35 Armenian haplotype, are these are three most significant Albanian haplogroups.
According today's knowledge about haplogroups Albanians probably lived somewhere in today's Romania or close in that region.
It is interesting that Albanians have the highest R1b ht35 Armenian haplotype in the Balkans, 14.7%, but Romanians have not much smaller, about 10.2%, (probably with big differences among regions).
It means that based in haplogroups and another things we can fairly precisely to locate place in Romania or somewhere in region from which Albanians came to the south Adriatic coast and neraby mountains. And it is possible that Albanians came after Illyrians merged with another tribes and disappeared from the hystorical scene.
From today's knowledge the most likely conclusion is Albanians can't have link with Illyrians.
