[QUOTE]Originally posted by the lioness,: [QB] [QUOTE]Originally posted by Doug M: Case in point, if you sample all the populations in Libya from the coasts all the way down to the Southern regions, you will see a lot more genetic diversity than what is implied by the current sample sets, which tries to fit all Libyans into one population cluster genetically. The problem is all the populations in Libya DON'T fit into the same population cluster. The populations nearer to the coast have more Eurasian ancestry as would be expected and the ones in the South have more African ancestry [/QUOTE]Doug makes a lot of claims but he never has the genetics data from articles to back it up. [IMG]http://www.catsg.org/cheetah/07_map-centre/7_1_entire-range/thematic-maps/human_density_africa_2000.png[/IMG] ^^ this is the population density of Africa. Let's look at Brazil for comparison. Native Brazilians comprise less than a half of one percent of the population. Somebody might say " well what about the people deep in the Amazon rainforest, why didn't they include them in the sample?" You [i]can[/i] include them in the sample. But if talk about the average in Brazil they comprise less than one percent. So it doesn't matter how many remote region you go to and take samples, that population is tiny compared to Europeans and Africans. People seem to not understand demographics. You can sample every group in all the remote regions of a country, that does not change the compound genetic averages for the country or region. And if we look at the YDNA of the berbers in the Maghreb, North Africa it is largely E-M81 and that is not common in Sub Saharan Africa, neither is the most common berber mtDNA, haplogroup H. So there is a notable genetic difference in most berbers. Are there some berbers who have more SSA lineage, yes. But they are not enough in number to say that North Africans are no different genetically from SSA Africans [/QB][/QUOTE]
