A large team of researchers affiliated with a host of institutions across Italy has used DNA found in the dental calculus of ancient peoples to help trace changes to the human diet during the transition from hunting to agriculture in Italy over thousands of years. In their paper published in the journal Nature Communications, the group describes their study of calcified plaque found on the teeth of people living during the Copper, Neolithic and Paleolithic Ages to learn more about changes wrought by a move from hunting for food to growing it.
