Using ADMIXTURE17 and principal-component analysis (PCA)18 (Figure 1A), we estimated the average proportion of non-African ancestry in the Egyptians to be 80% and dated the midpoint of the admixture event by using ALDER20 to around 750 years ago (Table S2), consistent with the Islamic expansion and dates reported previously. .. The affinity of the Egyptian African component with the modern East and West African populations (green component in Figure 1B, K ¼ 5) could be due to either a continuity of human presence in the area or recent gene flow from neighboring African regions resulting from demographic processes ..” [/i] --Pagani et al 2015.
