Syrians are genetically closer to Greek Peloponnese, Ashkenazim, Greek Islanders and Southern Italians than to Saudis.

This shows that the "Arab" status of Syrians is mainly due to cultural factors. It did not mean that Syrians (or Lebanese) absorbed a large amount of Arabian Peninsula ancestry. Groups like Greek Islanders, Peloponnese, Southern Italians and Ashkenazi Jews are genetically closer. This fact debunks:

Extreme Palestinian supporters: Who believe Ashkenazi Jews are "Eastern European converts". The European component Ashkenazi Jews is OVERWHELMINGLY Southern European alongside a substantial Levantine ancestry.

White supremacists: Because certain European subgroups have strong affinities with "non-Europeans" debunking the absolute lie that "Europeans are homogenous between themselves but distinct from all others".

Arab supremacists: Who believe that all "Arabs" share a common ancestry. They don't.
