“This wasn't just survival; it was a flourishing. Today, the highest global frequencies of I2 are found in the heart of former Illyrian territory—specifically in modern-day Croatia and Bosnia. This suggests that the "original" Illyrians were just as much descended from ancient European hunters as they were from Steppe warriors.”

it was flourishing bc whgs had already been killed of. Ironically the i2 in slavs might not even be native to them but admixed through them by eastern germanics or perhaps dacians. this doesnt mean yugos are those, bc white serbia/ croatia was absent of this. its also why sorbs have more ev13 than i2a1b and in general have very little i2a1b.
