DNA Reveals Italians Aren t Who They Think They Are

Italy has the highest degree of internal genetic diversity of any country in Europe — and the reason is buried in twelve thousand years of population replacement. A landmark 2019 study in Science sequenced one hundred and twenty-seven ancient genomes from Rome and central Italy spanning the Mesolithic to the Medieval period. The results showed that the people who built Iron Age Rome were genetically almost nothing like the people who lived there during the Empire. By the Imperial period, most residents of Rome carried Eastern Mediterranean and Middle Eastern ancestry, vastly outnumbering those with local Italian profiles. When the Empire collapsed, Germanic and Central European ancestry flooded in. Modern Italians are not one people — they are layers. Northern Italians carry more steppe and Central European ancestry. Southern Italians carry more Eastern Mediterranean, Greek, and North African. Sardinians are the closest living Europeans to the original Neolithic farmers. The Etruscans — long thought to be foreign — turned out to be genetically local. And the Romans themselves were a genetic crossroads that mirrored whatever territory they controlled at the time.
