[QUOTE]Originally posted by beyoku: [QB] Here is my "Question". Its somewhat long winded so Dr. Ketia can get a feel of what I am looking for. The genetic community has seen a lot of ancient Eurasian samples over the past few years. There are multiple lines of evidnce showing genetic turnovers in Eurasia. Differnet levels of genetic substructure some of which are quite widespread connect dislocated populations like "Basal Eurasian" and "ANE". While i am not too versed in European genetics it would seem that populations from the Neolithic Near East and Eurasian Steppes were some of the most sucessful latecomers in terms of Uni-Parental DNA, autosomal data and especially language. There have also been some surprises, one being that the main male Haplogroup in Europeans (R), derives from a subclade of the South East Asian lineaege of K2b2. While Ancient DNA in Africa exists and more is forthcoming there is still a lot to be desired. Some of the main avenues for migration such as the Nile Valley and Sahara-Sahel Belt are lacking in samples. [b]Using Eurasia as a model[/b], and drawing from your expertise as far as the study of African physical remains, language, pottery styles, stone/bone tool usage, fossils etc........[b]What type of Genetic Substructure and turnover would you expect to see as the Ancient Samples come in? What population centers would be best sampled in trying to reaveal some of this anceint diveristy and how it relates to population movements of the past and contemporary Africans?[/b] Something like Barbed bone points show an African tradition spaning a very long distance with possible extreme continuity. This could somewhat be said of Sahara Pottery or the aqualithic as well. We (non Academic Hobbiest) can hypothesized some of this stuff but its really going to take some years of study for some of us to really know what this means in terms of populations affinity among contemporary humans in Africa. Thank you for your time. [/QB][/QUOTE]
