    Cushitic haplogroup

    So what haplogroups fit the criteria for cushitic people? because im researching and there seems to be plenty of haplogroups that belong to the horn of africa but which ones are considered historically and genetically the first "cushitic" haplogroup?

    Thank you in advance

    Here's some threads from a very informative blog that might answer some of your questions:

    Thank you for the informative information bro, but in terms of Y-dna which haplogroup is considered the main haplogroup for Cushites? E-V1515?

    Np compadre!

    Good question - I wish I had an answer for you.
    PM any of these members and they'll be glad to either point you in the right direction for references or provide you with a thorough response: Awale, PuntDNALKing, Lank, Drobbah, Deftextra


    Here's some more Ethiopian Y-DNA info from which you might draw some conclusions; there's E-V1515 data as well: ETHIO HELIX ኢትዮ:ሒሊክስ

    The Kingdom of Kush was an ancient Nubian kingdom and mtDNA haplogroup M2 was found at the highest frequency in Northern and Southern Nubia at 39.1%. A back migration from the Indian subcontinent to East Africa has been suggested by González et al. (2007) as African M lineages are younger than Indian M lineages. The first M1 backflow to Africa, dated around 30,000 ya, could be forced by climatic conditions.

    Mitochondrial M lineages in Ethiopia were first detected by RFLP analyses [51]. To explain its presence in that area the authors suggested two possibilities: 1) the marker was acquired by Ethiopians through interchanges with Asians or 2) it was present in the ancient Ethiopian population and was carried to Asia by groups who migrated out of Africa. Later, the second hypothesis was favored and a single origin of haplogroup M in Africa was suggested, dating the split between Asian and African M branches older than 50,000 ya [22]. Although not completely discarding this last scenario other authors considered that the disjunctive was unsettled. The vast diversity of haplogroup M in Asia compared to Africa pointed to the possibility that M1 is a branch that traces a backflow from Asia to Africa [7,23]. Due to the scarcity of M lineages in the Near East and its richness in India, this region was proposed as the most probable origin of the M1 ancestor [7,52]. However, recent studies based on Indian mtDNA sequences [24,25] have not found any positive evidence that M1 originated in India. Nevertheless, the inclusion of M1 complete mtDNA lineages in the construction of the macrohaplogroup M phylogeny clearly established that the antiquity of Indian lineages, as M2, as compared to Ethiopian M1 lineages support an Asian origin of macrohaplogroup M [24].

    "Based on mitochondrial phylogeography it was proposed that M lineages expanded with the coastal route to southern Asia and Oceania"

    Interesting paper, that might explain some of the ASI and SE Asian affinities I get on different ancient admix-calcs -- there's even the odd accompanied trace of Papuan and Oceanian at ~2% levels. Some of the ASI affinities of family members are >5% which seems pretty out-of-place for persons that score >99% SSA on modern calcs (ie. no modern NA or Horner ancestry) -- I guess that makes sense if this backflow to Africa is far dated; 30kya

    This could be an insightful separate thread, I'd be interested to compare ancient admix results of other Africans.

    These are two different things you are mixing up. The Northern and Southern Nubia data is in reference to Y-Chromosome M2 or E1b1a. So far the distribution of E1b1a in such high frequencies has not been duplicated by modern studies that use the current ISOGG diagnostic SNP's. Its presence in Egypt is generally not that high and in Sudan its non-existant. The second half of your post is speaking of maternal lineage M1.

    A high frequency for hg M1 was observed among Asiatic speakers in East Africa who are associated with Nubia. According to Stevanovitch et al. (2004), the M1 haplogroup frequencies were 20% in the East African population and 10% in the Nubian population. The Cushites were from the area of the kingdom of Kush, also known as the Nubian kingdom of Napata. The wrong frequency in my previous post was actually about hg E-M2, taken from an obscure website on ancient Egypt.

    The M1 haplogroup frequency in Gurna is similar
    to that observed in the East African population (20%)
    (Passarino et al. 1998). The M1 haplogroup was observed
    in the Nile Valley population (7%), Nubian population
    (10%) (Krings et al. 1999), Bedouins (7.1%),
    Druzes (2.2%) and Palestinians (1.7%), but it was not
    found in any other Near Eastern populations (Richards
    et al. 2000).

    According to the population pairwise differentiation
    test (Appendix Ib), most of these populations appear not
    significantly different (with alpha value equal to 0.01),
    with the exception of the outgroup which is different
    from all the other populations. Only the Nubian population
    from Kerma and the Sudanese population from
    Dinka display a significant difference with some populations
    (Kerma with Assiout, Mansoura, Upper Egypt
    and Dongola populations, and Dinka with Kerma and
    Mansoura populations), although the Fst values are under
    0.10 for all these populations.

    Here's a more recent paper (2016) that also suggests a possible back to Africa migration from India to East Africa; the presence of M1 is cited as supporting evidence.

    Using autosmal ancestry-specific allele frequencies and a graph-based model implemented in TreeMix, the paper estimates different migration events which happen to show "non-tree-like behavior" :

The fourth migration event indicated gene flow between Indian ancestry and the common ancestor of Arabian, Levantine-Caucasian, Northern European, and Southern European ancestries. In conjunction with the second migration event, this event connects India to East Africa. Taken together, these two events are consistent with the presence among East Africans of the mitochondrial DNA haplogroup M1, possibly reflecting migration from India to East Africa following the Last Glacial Maximum13,14,15.
