Albanians are not the Han Chinese therefore
auDNA varies a lot according to which region we are talking about. Malesia and East Kosovans are not even in that reference panel. IA Illyrian auDNA is much higher in our results. As for the E1b-V13, R1b-Z2705 everything indeed points to a more Eastern/Central pathway in the Balkans.
As for all available IA Illyrian Y DNA they are pretty J2b-L283 heavy. In Patterson et. al 8 out 9 IA samples are J2b-L283 the R1b sample was P1312 I think, though I don't recall what he clustered with. In MBA Posusje the only sequenced Y DNA is J2b-L283. The "R1b" clades from the western Balkans so far are all over the place so no real pattern that shows one specific clade being more prevalant.
Also this overestimates by a zillion the IA Illyrian like component in Horvats. Modeling does not show actual ancestry (Southern Germans for sure aren't IA Illyrian heavy

) it barely even gives a hint at a possible ancestral composition. It also is prone to overestimation and overshifting.
It matters more for Germans than Balkan people, because in Germans its more Southern Bell Beaker/Celtic ancestry than anything, in the Balkan a large fraction is basically from the same source, and the composite being that IA_HRV and later populations of the region.
We just don't have enough ancient samples from Albania, Kosovo, Macedonia and Montenegro. BGR_IA does not and cannot represent the autosomal profile of ancient South-Eastern Europe.
Its the best we got, but of course, like I said on every occasion, we all want better samples. Its however not that far fetched to assume that a combination of BGR_IA and Mycenaeans can approach the local Eastern Balkan component. For one, we see it on the PCA that throughout Pannonia and up to the Western steppe such profiles pop up. Where do you think they came from? Not from Greek colonists only, that's a given. They will be brought there also, at least in part, by Basarabi and Psenichevo settlers, which represents kind of a backflow along the Channelled Ware networks established in the LBA-EIA.
Overall the distribution is already quite good, you get higher scores for East vs. West Balkans for group averages in a reasonable ratio.
You'd think Riverman who has such a terrible track record would learn from his mistakes and wait for more samples, but it appears that he simply cannot stop obsessing over undermining Albanians in every turn he gets.
I'm not undermining anything and surely not Albanians, that's ridiculous. And "my theories", what exactly do you mean? That J-L283 being associated with Illyrians-Pannonians and possibly spread with an expansive wave from MBA Tumulus culture groups? Or that E-V13 spread with Channelled Ware and Psenichevo-Basarabi, being basically Proto-Thracian?
What's stupid about that and which mistakes do you see? All samples so far proved me right. No E-V13 in the western groups, a lot North and East of the Danube, just like expected going after such an explanation.
Just in case you didn't notice: E-V13 and J-L283 are not copyrighted by Albanian people and theorising about their origin has not necessarily the goal of "undermining" anything. If anything, such a perception of debates about those haplogroups and ancestries is...
I usually just write something in threads related to Albanians if there is something
a) interesting about E-V13 in them
or
b) theories of more general interest, like about E-V13, related Balkan haplogroups and larger scale prehistorical and historical population movements being debated. If someone writes utter nonsense about West Balkan Illyrian origins of E-V13, I will of course correct that and try to prove my point.
Actually I considered that theory as well, but its the recent samples from the last 3 years which taught me otherwise. Just so you know.
