The Truth About Ethiopian DNA Is More Complicated Than We Thought

The Truth About Ethiopian DNA Is More Complicated Than We Thought Ethiopian populations carry some of the most genetically diverse profiles of any people on earth, reflecting a history that includes ancient African lineages predating the out-of-Africa migration, a major back-migration of western Asian ancestry between 3,000 and 7,000 years ago, Nilo-Saharan admixture from the north and west, and deep divergent lineages preserved in southwestern Ethiopian populations like the Gumuz and Ari. The 4,500-year-old Mota cave genome confirmed that western Asian ancestry was absent from the Ethiopian highlands before the mid-Holocene. Ethiopia contains more than eighty ethnolinguistic groups speaking languages from four different language families, and genome-wide studies have confirmed that different Ethiopian populations carry measurably distinct ancestry profiles. Ethiopia is also one of the most important fossil sites in the world, with Homo sapiens remains dating to approximately 195,000 years ago recovered from the Omo Kibish site. This video draws on ancient DNA research, modern population genomics studies, and the broader literature on African genetic diversity. All sources linked below. Sources: Gallego Llorente, M. et al.
