This is all very speculative but here it goes:I have collected a lot of historical information trust me, but i am new to this genetics thing and was asking about the similarities of albanians to greeks and also to illyrians? Yllirians?

E-v13 were the pelazgians, indigenous inhabitants from the stone-age. Then came minorities of Indo-European invasions of: Greeks, Illyrians, and Thracians. Illyrians and Thracians came from the North-West (Germany) through the Danube corridor, Greeks came from the North-Eastern steppes (Russia, but they're not slavic). These tribes mixed with the Pelasgians. Then the new Illyrians and Greeks were hit by waves of phoenicians, persians, and romans. Then they were hit by waves of slavs. That's why both Albanians and Greeks have close percentages of the same bizarre mix of y-dna.
The Illyrians of Croatia and Bosnia were somewhat decimated after the Bato rebellions. Then there was a period of dark ages after the fall of the Roman Empire, when various barbarian tribes went through that area; and the latest permanent settlers were the slavs around the 6-th century.
