People of Helm Peninsula (so called Balkan" which is a disgusting Turkish word) with their dominant I2 haplogroup were on these territories for at least 25 thousand years and did not came from anywhere in recent history. Yes, there were foreign cultural influences and linguistic influences as well but the core DNA of the indigenous people of Helm did not change.
