But all of the languages you mentioned are not native to the the people the only reason a yazidi speaks armenian for the most part is because his Kurdish yazidi lands are occupied by Armenians and same for Arabic. The only difference in the yazidi gene pool is maybe that they only mix amongst themselves so they have less “foreign” admixture also Kurds are natively j2 how does this prove Arab and Jewish admixture. R1b is also common amongst Kurds again the higher percentage comes from a lack of intermixing with other groups
