Modern Tuscans show no genetic relationship to the Etruscans who occupied the area during the Bronze Age, Italian researchers have found. While there is a genetic link between Medieval Tuscans and the current population, no link could be found to inhabitants from the Bronze Age, David Caramelli of Florence University and Guido Barbujani of Ferrara University said. Immigration and forced migration have diluted the Etruscan genetic inheritance so much as to make it difficult to recognize, the researchers said in a release.
