[QUOTE]Originally posted by xyyman: [QB] Quote from Reviewers -- Saharan admixture in more recent times” was shown in 2012 using genomewide SNP array data from Egyptians (Henn et al., PLoS Genetics: Table 1). That is, the sub-Saharan African ancestry is of recent origin in Egyptians dating to AD 1250 (~24 generations ago). Indeed those authors argued that the source of this sub-Saharan ancestry is more likely to be Nilotic than West African as modeled in the current analyses. For example, Kujanova et al. (2009) analysis of mtDNA and Y-chromosomal data from an Egyptian oasis isolate from middle Egypt is not cited. They found that sub-Saharan mtDNA L-lineages constituted 30% of their dataset, indicating a strong sub-Saharan component on the maternal side, which was largely absent on the Y (6% M2-derived lineages). And in Pagani et al. (2015, AJHG) show that "the average proportion of non-African ancestry in the Egyptians to be 80% and dated the midpoint of the admixture event by using ALDER to around 750 years ago (Table S2), consistent with the Islamic expansion and dates reported previously.” -- [/QB][/QUOTE]
