    Default Population genomics of the Viking world (Ashot Margaryan et al. 2019)

    Abstract:

    The Viking maritime expansion from Scandinavia (Denmark, Norway, and Sweden) marks one of the swiftest and most far-flung cultural transformations in global history. During this time (c. 750 to 1050 CE), the Vikings reached most of western Eurasia, Greenland, and North America, and left a cultural legacy that persists till today. To understand the genetic structure and influence of the Viking expansion, we sequenced the genomes of 442 ancient humans from across Europe and Greenland ranging from the Bronze Age (c. 2400 BC) to the early Modern period (c. 1600 CE), with particular emphasis on the Viking Age. We find that the period preceding the Viking Age was accompanied by foreign gene flow into Scandinavia from the south and east: spreading from Denmark and eastern Sweden to the rest of Scandinavia. Despite the close linguistic similarities of modern Scandinavian languages, we observe genetic structure within Scandinavia, suggesting that regional population differences were already present 1,000 years ago. We find evidence for a majority of Danish Viking presence in England, Swedish Viking presence in the Baltic, and Norwegian Viking presence in Ireland, Iceland, and Greenland. Additionally, we see substantial foreign European ancestry entering Scandinavia during the Viking Age. We also find that several of the members of the only archaeologically well-attested Viking expedition were close family members. By comparing Viking Scandinavian genomes with present-day Scandinavian genomes, we find that pigmentation-associated loci have undergone strong population differentiation during the last millennia. Finally, we are able to trace the allele frequency dynamics of positively selected loci with unprecedented detail, including the lactase persistence allele and various alleles associated with the immune response. We conclude that the Viking diaspora was characterized by substantial foreign engagement: distinct Viking populations influenced the genomic makeup of different regions of Europe, while Scandinavia also experienced increased contact with the rest of the continent.

    For my own nationalistic reasons I first looked at individuals with large "Polish-like ancestry" (table S6). I looked at the sample with largest share of "Polish-like ancestry" (0.984) VK474.

    It is decribed as "VK474 Sweden Gotland Kopparsvik, Viking 900-1050 CE. Y-chromosome: E1b1b1b2a1a4 mtDNA: J1d

    What was a "Pole" (with atypical - Balkan? - male haplogroup) doing in Gotland one thousand years ago?

    Some other individuals desribed by the authors of the paper as "Polish-like":

    VK160, "Polish-like" 0.982, Russia Kurevanikha Kurevanikha, Viking, 10-13th centuries CE, R1a1a1b1a1a1c1c, C4a1a+195

    VK139, "Polish-like" 0.968, Denmark Funen Galgedil, Viking, 9-11th centuries CE, R1a1a1b1a1a1c1, J1c3k

    VK541, "Polish-like" 0.952, Ukraine Lutsk Lutsk, Medieval, 13th century, R1a1a1b1a1a1c1, H7

    VK340, "Polish-like" 0.858, Denmark Jutland Hesselbjerg, Viking, 850-900 CE, female, H1c

    VK542, "Polish-like" 0.711, Ukraine Chernigov Chernigov, Viking, 11th century, I2a1a2b1a1a, H5a2a

    VK473, "Polish-like" 0.706, Sweden Gotland Kopparsvik, Viking, 900-1050 CE, I1a1b, N1a1a1a1

    VK478, "Polish-like" 0.693, Sweden Gotland Kopparsvik, Viking, 900-1050 CE, female, H1m

    VK397, "Polish-like" 0.648, Sweden Skara Varnhem, R1a1a1b1a3a, J1b1a1

    I got bored with this, but there are alltogether 17 individuals with "Polish-like" ancestry in the range 50-100%, 8 with such ancestry in the range 25-50%, and 11 with such ancestry in the range 12.5-25%.

    So all these places as rightful Polish clay, right?

    Swedish Viking presence in the Baltic, and Norwegian Viking presence in Ireland, Iceland, and Greenland.
    Shouldn't that not just be Ireland and Iceland but Scotland too like Orkney and the Shetlands and NorthEast Scotland in general ?

    I'm looking at their mtDNA haplogroups to see if any match mine or is close to me. I am H1c12.

    There is an H1c3b, and a H1cg, four H1c, two H1c3, H1c7, and H1c21.



    I may be wrong but it's cool to think that one of the H1c's could be my ancestor (ancestress).

    My male haplogroup I1a3-Z63 found in Wielbark culture (supposedly Gothic) is absent in this dataset.

    Samples from Poland:

    VK153 Poland Bodzia Bodzia Viking 10-11th centuries CE Male R1a1a H1c3
    VK154 Poland Bodzia Bodzia Viking 10-11th centuries CE Female H1c3
    VK155 Poland Bodzia Bodzia Viking 10-11th centuries CE Female H1c
    VK156 Poland Bodzia Bodzia Viking 10-11th centuries CE Male R1a1a1b1a2a J1c2c2a
    VK157 Poland Bodzia Bodzia Viking 10-11th centuries CE Male I1 H1c
    VK200 Poland Czersk Czersk Viking 11-12th centuries CE Male R J1b1a1b
    VK210 Poland Kraków Kraków Medieval 11-13th centuries CE Male I2a H5e1a1
    VK211 Poland Cedynia Cedynia Medieval 11-13 centuries CE Male R1b1a1b W6
    VK212 Poland Cedynia Cedynia Viking 11-12th centuries CE Male R1a1a1b H1+152
    VK494 Poland Sandomierz Sandomierz Viking 10-11th centuries CE Male R1a1a X2c2

    R1a1a1b1a2a should be Z280/Z92.

    So out of 8 males 1 is I1, one is I2a, and 6 are R.

    Out of these 6 R, one is R, one is R1b1a1b, and four are R1a1a.

    It seems to look more or less like modern Polish distribution:

    R1a1 57.5%
    R1b 12.5%
    I1 8.5%
    I2*/I2a 5.5%

    Ancestry estimates are available for the 2 samples one female and one R1a1a1b1a2a-Z280/Z92 male:

    Sample British-like/North Atlantic Danish-like Swedish-like Norwegian-like Polish-like Southern European-like Finnish-like
    VK154 0 0.101 0.268 0.01 0.506 0 0.115
    VK156 0.001 0.013 0.209 0.001 0.513 0.006 0.258

    So they were half-Poles with the rest of their ancestry mostly from Sweden (20.9-26.8%), Finland (11.5-25.8%) and Denmark (1.3-10.1%).

    R1b1a1b1b-Z2105 was found in a single sample from Italy (VK535). The vast majority of other R1b
    samples belonged instead to the R1b1a1b1a-L11 clade, and were mostly distributed within its two
    main subclades: P312/S116-R1b1a1b1a1a2 and U106/M405-R1b1a1b1a1a1, of western and
    eastern distribution relative to the Rhine river basin.

    Baltic ancestry in Gotland
    Genetic clustering using IBS-UMAP suggested genetic affinities of some Viking Age individuals
    with Bronze Age individuals from the Baltic. To further test these, we quantified excess allele sharing
    of Viking Age individuals with Baltic BA compared to early Viking Age individuals from Salme
    using f4 statistics. We find that many individuals from the island of Gotland share a significant excess
    of alleles with Baltic BA (Extended Data Fig. 4), consistent with other evidence of this site being a
    trading post with contacts across the Baltic Sea.

    Several features are clear from Figure S11.9. Firstly, modern Finnish individuals are not like ancient
    Finnish individuals, modern individuals have ancestry of a population not in the reference; most likely
    Steppe/Russian ancestry, as Chinese are in the reference and do not share this direction.
    Ancient
    Swedes and Norwegians are more extreme than modern individuals in PC2 and 4. Ancient UK
    individuals were more extreme than Modern UK individuals in PC3 and 4. Ancient Danish
    individuals look rather similar to modern individuals from all over Scandinavia.

    The SNPs with strongest association with lighter hair and eye pigmentation phenotypes such as the
    ones in HERC2, OCA2 and TYR genes in humans are elevated in the Viking population, and the
    profile of allele frequency distribution is close to the present-day Northern European population
    represented here by the “CEU” (1000 Genomes Project) and the modern Danish population (“DK”)
    from IPSYCH case-cohort study. The frequencies of informative SNPs associated with pigmentation
    are presented in Figure S13.1.
    This suggests that the genetic profile of pigmentation SNPs we observe in northern Europeans today
    had been largely formed at the onset of the Viking period.
