[QUOTE]Originally posted by Amun-Ra The Ultimate: [QB] [QUOTE]Originally posted by xyyman: [qb] 3. In other words. These Sudanese Sahara region Great Lakes people seems to be the source of ALL the world's population. ALL REGIONAL SPECIFIC SNPs are found there!!!!! This is s strong indication of the source. Ie ORIGIN. [/qb][/QUOTE]Modern African people are not the origin of all the world population. Most of the modern A, B and E haplogroup developed much later than the exit of non-African from Africa (F descendant mutations on the Y-DNA side. M,N descendants on the MtDNA side). [b]This is what the study of haplogroup and population structure is all about. That is the time between the exit out of Africa and now.[/b] For example the P2 mutation is relatively rare in the rest of the world (beside in neighboring regions of Africa like Southern Europe, Yemen, the Levant). Same for any other African "SNP" like A-M13, B-M150, E-M2, E-M215, etc. For example, an African like you and me, assuming of course, who exited Africa relatively recently (after the OOA) probably met a F descendant (and M and N descendant) population when doing so. Ultimately admixing with them to various degree. Usually people in Europe or the Middle East for example who still carry a E-P2 (M215) mutation on their direct male line will still cluster with other specific Europeans or Middle Easterners from the region who don't carry the E-P2 mutation like R or J carriers. Their whole genome is more influenced by the rest of the F descendant population from the region than the relatively more recent P2/M215 migration. The same could be said about R carriers in Cameroon. [/QB][/QUOTE]
