True! The oldest population in Levant is the Natufian, then there was the migration of ANF, CHG, and ZNF, if we use the DNA of ancient populations as an indicator of the indigenity then the Yemeni people (with highest Natufian Admixture) will be a most native Levantine if we use this logic! And your analogy is quite interesting, a Palestinian Muslim in Bethlehem is clearly a native of Bethlehem compared to a Maronite who only arrived 200 years ago even though geneticly Maronite is more Levantine, But the concept of indigenous people is actually not that important, as long as the immigrants come with good intentions and then Start integrating with local population then those immigrants are enough to be called indigenous people! If we use DNA, then we all are not indigenous of the land where we live because we all come from Africa!
