Thread: East Eurasian admixture is based on a North-South axis in Europe.

  1. #1

    East Eurasian admixture is based on a North-South axis in Europe.

    It's been thought before it rises as we move from West to East but it rather has to do with Early Mesolithic - Paleolithic migrations from Siberia, Central Asia.
    With the rise of Neolithic farmer admixture the East Eurasian decreases and the same time the Basal Eurasian-African like genetic characteristic increases.

    Gedrosia K3 is the best calculator for this.

    Because it has just three components - West Eurasian, East Eurasian and Sub-Saharan African.

    1) Here is my result (Polish):

    Population
    E_Eurasian 2.83
    SSA -
    W_Eurasian 97.17

    2) Here an ethnic Swedish guy:

    Population
    E_Eurasian 5.00
    SSA 0.20
    W_Eurasian 94.80

    3) Here a North Dutch guy:

    Population
    E_Eurasian 2.21

    4) Here a Scottish guy:

    Population

    5) Here a Sicilian guy:

    Population
    E_Eurasian 2.01
    SSA 3.95
    W_Eurasian 94.04

    Surprisingly, the Scottish guy is actually much more East Eurasian (3,98%) than I am (2,83%).

    Even your chart still looks rising west to east to me.

    And you can see in references that Russians get Northeast Asian basic ancient component and it doesn't even show to 2% level in Baltics to the west. It also shows more to some southeast of the Baltics. It's more of rising to the west but also high in FInland due to Siberian migrations.

    I haven't found Gedrosia all that reliable. The Oralces for K3 put my mom as 0.0000 distance to Ukranian which is crazy.
    I think K3 also has too few components as there seem to be at least two distinct eastern components that come into play, one a very northern one and one or two that are eastern and northereastern (definitely drops off as you go west and to the Baltics).

    Also my dad clearly has some more eastern and northern ancestry than my mom but actually gets less E-Eurasian on this test, opposite of on almost all other tests.

    I think Gedrosia tends to make mistakes with Europeans.

    Oddly the Oracles for this puts my mom 0.0000 distance to Ukrainian when she is way Latvian and about 8-12% German (maybe some of this is Scandinavian) and maybe 2% Dutch and 2% Oceanian and yet my dad who shows some hints of maybe a trace of Ukrainian/ROmanian or such on all other tests mixed in with Latvian gets 0.0000 distance to Lithuanian. My dad also has at least one Finnish ancestor too. So I don't see how main or Oracles from this make sense.

    Yes it's odd for people in West Europe to be getting more East Eurasian than a Polish person.

    Here's my result

    This is outdated nonsense that doesn't take into account the non-Basal vs Basal Eurasian structure in Europe.

    So people from Scotland get a closer match to Lithuania from these Oracles than my mom who is like probably at least 84.5% Latvian for centuries....

    My BigY may indicate paternal line from East Prussia in the 3 to 4K year range. Will submit to Yfull when Bam file becomes available, may help refine range. Interesting what you can find with targeted testing.

    The Oracles weren't the primary point of this calculator. I am not sure why Kurd included them. Several posters were trying to estimate this basic admixture split in other ways that weren't too successful. So, at their request and as a favor, he put it up on Gedmatch for us to use. Setting aside the Oracles, the admixture results seem fine for my family members that I post regularly on this forum. There isn't much distinction at K3 between many populations that are somewhat similar, so I don't think I would pay too much attention to those Oracle results and just use this calculator for what it is - a quick estimation of a West Eurasian / East Eurasian / SSA split.
