Ashkenazim are mixed and isolated

What this means is that after you mix 50/50, if you become an island (separated by religious discrimination in Europe) you develop some traits that are unique and basically become a new group, because you mix in with yourself again and again

That said Ashkenazim do produce Levantine looking people often. Sacha Baron Cohen is well known for playing MENA people in comedy, but his cousin Simon Baron Cohen (UK psychologist) looks white as hell like Mark Zuckerberg. But it’s still in every family to make people of both types

Mixed Euro-MENA people also make people that look like European Jews, like Steve Jobs (Syrian/German) or Kevin O’Leary (Lebanese/Irish)

Euro Jews are definitely descended from Levantine people, however I don’t think this means indigenous. Indigenous implies a generational connection. Grandfathers of your grandfathers that lived there. Ashkenazim have a historical connection to Israel, through the Roman diaspora

Which is similar but different. And it becomes very political when you have things like Nationalism
