So here is a question. Who has changed more from the present to modern day -- Sicilians when compared to Late Bronze Age Sicily, or modern Greeks from Mycenaeans?

We cannot say that just because Sicilians plot closely today to LBA Sicilians that they haven't experienced more change by being pulled back and forth across a PCA plot as they mixed with Italics, Berbers, and Levantines among others. Greeks have only changed in one direction (Slavic).

So which group received more foreign input in the last 2500 years overall?
