The current population of Tuscany is not descended from the Etruscans, the people that lived in the region during the Bronze Age, a new Italian study has shown. Researchers at the universities of Florence, Ferrara, Pisa, Venice and Parma discovered the genealogical discontinuity by testing samples of mitochondrial DNA from remains of Etruscans and people who lived in the Middle Age as well as from people living in the region today. While there was a clear genetic link between Medieval Tuscans and the current population, the relationship between modern Tuscans and their Bronze Age ancestors could not be proven, the study showed.
     "Some people have hypothesised that the most ancient DNA sequences, those from the Etruscan era, could contain errors or have been contaminated but tests conducted with new methods exclude this," said David Caramelli of Florence University and Guido Barbujani of Ferrara University. "The most simple explanation is that the structure of the Tuscan population underwent important demographic changes in the first millennium before Christ," they said. "Immigration and forced migration have diluted the Etruscan genetic inheritance so much as to make it difficult to recognise".
     The scientific data does not necessarily mean that the Etruscans died out, the researchers said. Teams from Florence and Ferrara universities are working to identify whether traces of the Etruscans' genetic inheritance may still exist in people living in isolated locations in the region.
     The Etruscans lived mainly between the rivers Tiber and Arno in modern-day Umbria, Lazio and Tuscany, in the first millennium BC. By the sixth century BC they had become the dominant force in central Italy, but repeated attacks from Gauls and Syracusans later forced them into an alliance with the embryonic Roman state, which gradually absorbed Etruscan civilization.
