Recent studies have identified Northeast Africa as an important area for human movements during the
Holocene.Eurasian populations have moved back into Northeastern Africa and contributed to the genetic
composition of its people. By gathering the largest reference dataset to date of Northeast, North, and East
African as well as Middle Eastern populations, we give new depth to our knowledge of Northeast African
demographic history. By employing local ancestry methods, we isolated the Non-African parts of modern-day
Northeast African genomes and identified the best putative source populations. Egyptians and Sudanese Copts
bore most similarities to Levantine populations whilst other populations in the region generally had predomi-
nantly genetic contributions from Arabian peninsula rather than Levantine populations for their Non-African
genetic component. We also date admixture events and investigated which factors influenced the date of ad-
mixture and find that major linguistic families were associated with the date of Eurasian admixture. Taken
as a whole we detect complex patterns of admixture and diverse origins of Eurasian admixture in Northeast
African populations of today.
