    Ancient Nordic MtDNA

    Ancient Nordic mtDNA (Melchior et al. 2010)

    Linea Melchior et al.

    Using established criteria for work with fossil DNA we have analysed mitochondrial DNA from 92 individuals from 18 locations in Denmark ranging in time from the Mesolithic to the Medieval Age. Unequivocal assignment of mtDNA haplotypes was possible for 56 of the ancient individuals; however, the success rate varied substantially between sites; the highest rates were obtained with untouched, freshly excavated material, whereas heavy handling, archeological preservation and storage for many years influenced the ability to obtain authentic endogenic DNA.

    While the nucleotide diversity at two locations was similar to that among extant Danes, the diversity at four sites was considerably higher. This supports previous observations for ancient Britons.

    The overall occurrence of haplogroups did not deviate from extant Scandinavians, however, haplogroup I was significantly more frequent among the ancient Danes (average 13%) than among extant Danes and Scandinavians (~2.5%) as well as among other ancient population samples reported. Haplogroup I could therefore have been an ancient Southern Scandinavian type “diluted” by later immigration events. Interestingly, the two Neolithic samples (4,200 YBP, Bell Beaker culture) that were typed were haplogroup U4 and U5a, respectively, and the single Bronze Age sample (3,300–3,500 YBP) was haplogroup U4.

    These two haplogroups have been associated with the Mesolithic populations of Central and Northern Europe. Therefore, at least for Southern Scandinavia, our findings do not support a possible replacement of a haplogroup U dominated hunter-gatherer population by a more haplogroup diverse Neolithic Culture.

    With many interests I read the message about the frequency of haplogroup I
    in Denmark. I supposed that it is a typical Germanic haplogroup and it came
    from the Cro-Magnons and Aurignacs from France. From where came the
    haplogroup of the Germanics of the Iron Age? From Germany, France and
    Spain?

    The MTDNA studies are more rare and aren't that developed so i would be cautious in taking big conclusions right now.

    "I: Principally a European haplogroup, haplogroup I is detected at very low frequency across west Eurasia with slightly greater representation in northern and western Europe. Given its wide, but sparse, distribution, it is likely that it was present in those populations that first colonized Europe. This hypothesis is supported by the estimate its age—approximately 30,000 years. Bonnie Schrack in her mtDNA Haplogroup I project named this mtDNA haplogroup Iris."
