A 2016 study based on testing samples of Druze in the Syria (region) in comparison with ancient humans (including Anatolian and Armenian), and on Geographic Population Structure (GPS) tool by converting genetic distances into geographic distances, concluded that Druze might hail from the Zagros Mountains and the surroundings of Lake Van in eastern Anatolia, then they later migrated south to settle in the mountainous regions in Syria, Lebanon and Israel.
