I said to my wife as soon as I saw the headline “I bet that this headline is a breathless exaggeration and scientists haven’t proved a darn thing.”
The Etruscans have the same genetics as the Italic peoples around them, eh? Ok, where did their language come from then, and why isn’t it like theirs?
Etruscan origins has been a 2000-year-old puzzle, and while this study contributes an interesting data set to the discussion, “solved” the matter it certainly hasn’t.
Etruscan was a non-Indo European language.
The Indo-European language “homeland” was the “Pontic Steppe”, from which migrating/conquering tribes (the “Aryans”) went East and West.
Etruscan could have been a native tongue of the pre-Aryan European natives, that persisted in the path of the new peoples. Sort of like the Basques - note that Basque-related languages were once prevalent over a vastly greater area than today, even in historical times. Its possible this is a similar case.
