[QUOTE]Originally posted by Mystery Solver: [QB] A recap, courtesy of X-ras, his post in: [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=004598;p=1#000000][i]Interesting notes on Delta Egyptian DNA[/i][/URL] Polymorphic Alu insertions and genetic diversity among African populations. Publication Date: 01-OCT-05 Publication Title: Human Biology Author: Herrera, Rene J. "Egypt, which presents the highest number of loci in Hardy-Weinberg disequilibrium, is of particular interest in light of the notoriously heterogeneous genetic composition of this region as a result of past and present migrations. Historically, Egypt has been the recipient of constant genetic flow from northeastern sub-Saharan Africa by means of the Nile River. Moreover, a number of incoming migrations, such as the Middle Eastern penetrations during the introduction of agriculture to Africa as well as later occupations by the Greeks, Romans, and Arabs, have all contributed to a complex genetic landscape in this area (Lucotte and Mercier 2003)." And "The population of Egypt examined in this study [b]was collected in the Nile delta[/b] and represents individuals of Arab, Berber, and possibly ancient Egyptian descent....[b]The observed affinity between Egypt and Europe might represent a North African signature in the European genetic landscape as a result of historical migrations originating in Africa and reaching Europe through the Levantine corridor (Luis et al. 2004)[/b] or the Strait of Gibraltar. Conversely but not exclusively, the European genetic influence on North Africa may be the result of ancient back-flows into the southern Mediterranean basin and/or the consequence of the more recent Minoan, Greek, and Roman penetrations into the area. In light of the proposed Central Asian origin of extant European populations (Semino et al. 2000; Wells et al. 2001), the observed close association between Egypt and Indian groups in the phylogenetic trees may represent a manifestation of this Central Asian footprint in the European genetic background. [b]Furthermore, the fact that in both phylograms (Figure 3) the Kenyan and Rwandan populations (Rwanda in particular) are the most closely related to the Egyptian group attests to the role played by the Nile River as an avenue for genetic flow between groups located to the north and south of the Sahara Desert.[/b] Previous analyses with the HpaI mtDNA marker have also suggested the occurrence of south-north gene flow through the Nile valley between sub-Saharan populations and northeastern Africa (Fox 1997). ^Please note that my posts herein, isn't to support the idea of mass migration from AE to western Africa, but to highlight the futility of argumentation which essentially amount to a euphemism for [i]west Africans being some sort of a distinct "race"[/i], by way of talking about non-overlapping in both cranio-metric traits/phenotype and genotype across the said regions. One need not make such futile assessments to necessarily argue against "mass" migration from the northeastern corner of Africa. [/QB][/QUOTE]
