New Mesopotamian samples from Bakr Awa. Very cool stuff. Upper Mesopotamian ancestry here likely comes from Hurrians (and to a lesser extent possibly East Semites). The Southern Caspian ancestry may be from Kassites (Burnished Grey Ware intrusion into the Northern-central Zagros and surrounding foothills). The Canaanite ancestry is likely from Aramaeans (we need the dates for these new samples to confirm this) The Indo-Iranian likely comes from Mitanni (we need dates to confirm these aren't simply West Iranians) The Lchashen Metsamor is a placeholder for Trialeti-Vanadzor ancestry (which has a lower quality average). This ancestry likely comes from Northern-central Zagros populations (like Lullubians, Turukkaeans, and Gutians) There's likely Amorite admixture here but it's difficult to parse the Northern Levantine profile from the Upper Mesopotamian one. The Amorite related gene flow will fall into the Canaanite and/or Upper Mesopotamian buckets in this overly complicated model
