[QUOTE]Originally posted by rasol: [QB] [QUOTE]Originally posted by qoucela: No one knows what lineages were in Arabia in ancient times so we don't know what lineages originated in Arabia. [/QUOTE]Respectfully, this is not and accurate statement either. In fact it's a not atypical comment of those very unfamiliar with genetics. The basic principal of modern population genetics is that your blood carries your history. We can tell a goodly amount about the ancient historical physical relationships between any two populations by examining their current dna. DNA is biological history. You are well intended and make many good remarks. So I will add some information about haplogroup E which hoepfully you will find useful. Halogroup E originated in Africa 45 thousand years ago. Outside of Africa this halogroup and all it's pre mesolithic variations are almost uknown. There are serveral subgroups E1, E2 and E3, further E3 is divisible to E3a and E3b. E1 and E2 originate in the sahel and are 'almost' non existent outside Africa. E3 originates in East Africa and splits into E3a which branches off into West Africa and E3b which is East African. E3b spread from East and SouthEast Africa into West Africa, SouthWest Asia and Europe. By contrast, in Arabia the most common lineage is J. J is considered native to WestEurasia. E3b and E3a are present in lower levels and denote "African admixture" in Arabs. Understand then that Taureg have overwhelming E lineages and a very high amount of E1/E2 which are native to the Sahel from 40 thousand years back. They have relatively little non African paternal lineage and what little they do have likely reflect post Islamic Arabian admixtures. Therefore they do *not* come from Arabia. Arabia is the most over-rated - in terms of genetic ancestry - region of the world for Africans, because many Muslims, including some Hausa Nigerian, try to trace their ancesty back to Mohammad, and some Jews try to trace back to King Soloman. European theorists often exploit this and run with it, but actually at present, no geneticist theorises and Arabian origin for the Taureg because they can be proven genetically to be native to AFrica. Genetics as ever, is a merciless gadfly to many exotic origin theories which otherwise float around forever, because they are vague and speculative enough that they can not literally be proven nor disproven. Hope this helps. [/QB][/QUOTE]
