I thought the prior conventional wisdom was the Etruscans migrated from Anatolia?
Well, that they were related to some peoples that may have existed in Anatolia and Greece, the “Pelasgians” who populated that region before the arrival of the Indo-European speaking ancestors of the Greeks. Its possible, IMHO, that these pre-Aryan native cultures of the northern Med extended to Northern Italy.
That was the ancient view, and since they were much closer to the problem, I'd go with that.
Their language appears to have been rooted in the e Med, DNA research on their midden heaps show that their livestock had roots from the e Med, even their tombs echo the carved tombs of the Aegean. Their trade and cultural links were with the e Med (particularly the Ionian Greeks and the Phoenicians, and with their Carthaginian kindred).
Also I wonder where all this supposed Etruscan DNA came from, considering that, AFAIK, they really preferred cremation.
