    EDIT: I see this was also posted in the forum under DNA in the News which is probably the more appropriate thread for comments...

    Thank you for the link.

    From the paper (via Dienekes' blog):




    All Ashkenazi J, T, and H, or ~30% of the total frequency are "European" ?? I need to read the paper.

    EDIT - Another reason I need to read the paper, the entirety of mtDNA K, or ~32% is labelled "European" ?

    mtDNA K is significant in Syrians (Syrian and Jordanian frequencies from Badro et al. below). One should consider Jewish tradition, and the "wandering Aramean [~Syrian]." Not that there is necessarily a connection, but I firmly believe that the collective record should always be considered in such analyses.

    Code:
    ----	N=234	N=98	N=290
    ----	SYR	ASY	JOR
    A	0.4%	0.0%	0.3%
    D	0.0%	0.0%	0.3%
    H	24.4%	25.5%	26.2%
    HV	7.7%	14.3%	6.6%
    I	0.9%	1.0%	1.4%
    J	11.5%	19.4%	8.6%
    JT	0.4%	0.0%	0.0%
    K	10.3%	2.0%	3.8%
    L	6.0%	0.0%	10.0%
    M	0.9%	0.0%	1.4%
    N	4.7%	1.0%	5.9%
    R	2.6%	0.0%	0.0%
    R0	2.6%	0.0%	3.4%
    R2	0.0%	0.0%	0.3%
    T	11.1%	8.2%	9.0%
    U	10.3%	26.5%	19.3%
    V	1.3%	0.0%	0.3%
    W	3.4%	1.0%	1.4%
    X	1.7%	1.0%	1.7%

    From the paper:
    Here we focus on both major and minor founders, with a much larger database from potential source populations.
    Sorry to vent, but this does nothing but convince me that many of the folks who conduct these studies are ignorant of the realities of the Middle East.

    From a past post:

    Zero Published Autosomal Samples (Y-DNA and mtDNA data is lacking for many groups as well)

    Levant
    Maronites
    Melkites
    Ma'loula Aramaeans of Syria
    Alawites
    Palestinian Christians (?)

    Mesopotamia
    Assyrians – "Nestorian" Church
    Assyrians – Chaldean Catholic Church
    Assyrians – Syriac Orthodox Church
    Jews - North Iraq, North Iran, SE Turkey
    Mandaeans

    ^^ Not an exhaustive list.

    For those who come upon this thread, it is worth referring to this thread: Ancient DNA Analysis of PPNB farmers.

    One bit in particular is relevant to the findings of the Costa et al. paper "A substantial prehistoric European ancestry amongst Ashkenazi maternal lineages":

    Another interesting case are the Ashkenazi Jews, who display a frequency of haplogroup K similar to the PPNB sample together with low non-significant pairwise Fst values, which taken together suggests an ancient Near Eastern origin. This observation clearly contradicts the results of a recent study [Costa et al.], where a detailed phylogeographical analysis of mtDNA lineages has suggested a predominantly European origin for the Ashkenazi communities.
