I've been following this study of the origins of the Etruscan people for some time, with considerable interest. The EurekaAlert website presents the latest piece of the jigsaw. Here's an extract:

The long-running controversy about the origins of the Etruscan people appears to be very close to being settled once and for all, a geneticist will tell the annual conference of the European Society of Human Genetics today. Professor Alberto Piazza, from the University of Turin, Italy, will say that there is overwhelming evidence that the Etruscans, whose brilliant civilisation flourished 3000 years ago in what is now Tuscany, were settlers from old Anatolia (now in southern Turkey).

. . .

The scientists compared DNA samples taken from healthy males living in Tuscany, Northern Italy, the Southern Balkans, the island of Lemnos in Greece, and the Italian islands of Sicily and Sardinia. The Tuscan samples were taken from individuals who had lived in the area for at least three generations, and were selected on the basis of their surnames, which were required to have a geographical distribution not extending beyond the linguistic area of sampling. The samples were compared with data from modern Turkish, South Italian, European and Middle-Eastern populations.

“We found that the DNA samples from individuals from Murlo and Volterra were more closely related those from near Eastern people than those of the other Italian samples”, says Professor Piazza. “In Murlo particularly, one genetic variant is shared only by people from Turkey, and, of the samples we obtained, the Tuscan ones also show the closest affinity with those from Lemnos.”
