what do you mean ''autochthonous''? as i said, greeks are not only native within the borders of modern greece but also turkey. dorians come from the north (modern day thessaloniki area)  ionians from the south (peloponese) achaeans from modern day izmir area in turkey. aeolians from thessaly. pelasgians is a term of the inhabitants of greece before greek civilization (written history) emerged. we don't know exactly who they were and if they are or aren't the same people as the greeks. and lastly, it's ''autocthony''. ''autoctony'' means suicide.
