The linguistic similarity between “Shardana” and “Sardinia” may be coincidental.

The Nuragic civilization’s development is complex and does not obviously fit a simple model of migration from the eastern Mediterranean.

Ancient DNA evidence from Sardinia has shown that the population of the island was genetically distinct from mainland Mediterranean populations for a very long time, a distinctiveness that reflects their descent from Neolithic farmers who arrived from Anatolia thousands of years before the Bronze Age.

The arrival of Shardana refugees or migrants would have added to this genetic background, but whether it would be detectable as a distinctive component depends on the scale and nature of any migration.
