A new study suggests that Sardinians experienced less genetic turnover than populations living in mainland Europe. When large-scale migration is thought to have occurred during the Bronze Age in Europe, Sardinia’s population remained in place.
An international team of scientists analyzed the genomes of 70 Sardinians whose remains were recovered from more than 20 archaeological sites spanning a period of about 6,000 years. The scientists then compared the Sardinian DNA to DNA collected from other ancient and modern peoples. The researchers determined that Neolithic Sardinians were closely related to their contemporaries in mainland Europe. Sardinian genetic ancestry remained stable through 900 BCE, although a new style of stone towers did appear on the island in this century. The 900s BCE are important because that is when major population movements occurred in Europe. But they apparently did not impact Sardinia as much.
The DNA supported later population movement on the island, such as the arrival of the Phoenicians from what is now Lebanon, and the Punics, from what is now Tunisia, as early as 500 BCE During the Roman and medieval periods, the scientists also found evidence of migration to the island from Italy and Spain.
