    Default More DE* found in Nigeria?

    Veeramah et. al 2010 reports DE*(x E) haplotype frequencies found in South Eastern Nigeria for the following samples taken:

    1) Ibibio from Ette; 1/50
    2) Ibibio from Mkpok Ndon Eyo; 1/50
    3) Ibibio from Obong Itam; 1/50
    4) Igbo from Calabar ; 1/100
    5) Oron from Eyo Nsik & Eyo Ekpe ; 1/73
    6) Igbo from Enugu ; 1/57

    Total DE*(xE) found in South Eastern Nigeria; 6/1222 = 0.5% (None found in Cameroon and Ghana)

    Before this paper, Weale et.al 2003 had reported DE*(xM174,M96) in Nigeria; 5/1247 = 0.4%

    So what now? Are people still debating where DE first popped up? I've read about people speculating that it could be due to back migration from Asia. I'm guessing it appeared in North East Africa or the MidEast.

    Whoever said it appeared in the Middle east is a liar, it appears in Nigeria and one person in Tibet, no if it back migrated why isn't it found any place in between Tibet and Nigeria? I'm not asking you specifically this question, just in general.

    Oh, nobody said it was found in the mideast. That was my guess of it's first appearance, based on the geographic distribution of the known DEs. I'm not sure it really matters where it was found, at least to me. It could be anywhere between Tibet and Nigeria. It's looking more and more like Africa than anything now.

    Plus there is Guinea Bissai - 1 DE*
    So we are at 12 DE* in Africa vs 2 DE* in Asia.

    DE* and E* arose first probably in West Euroasia?

    http://www.biomedcentral.com/1741-7007/6/45


    "We identified four E-M40 individuals in the northwestern Han populations, a reflection of recent gene flow from Central Asia"
    D*-M174 is absent in Afrika!

    "In surprise, we observed two DE* in the Tibetan samples, which was previously only observed in Africa (Nigerians), but not in other world populations."


    " the age of D*-M174 is (66,392 ± 1,466)"

    while E-M40 is 50,000 - 55,000 years

    Add this to the 16 or so E* lineages that were found in Africa.

    http://en.wikipedia.org/wiki/Haplogroup_E_(Y-DNA)

    "The most basal lineages, paragroup E*, have been found in a single Bantu-speaking male from South Africa[1], amongst pygmies and Bantus from the Cameroon/Gabon region,[9] and in two individuals from Saudi Arabia."

    All other members of haplogroup E belong to one of its already identified subclades.

    http://www.biomedcentral.com/1471-2156/10/59

    Interestingly, basal E-M96* (n = 2) and J-M304* (n = 3) lineages have been detected, for the first time, in the Arabian Peninsula.


    The point is Haplogroup E* is very rare! Most of its lineages arose in Africa but it is not cleare where E itself first arose!

    5 lebanese men were found to be E*.
