    The South Asian and Southeast Asian are interesting. I have not seen this in Amerindians from North America, but it supports what I have read about the possibility of a second wave of migration coming from SE Asia through Polynesia before landing in South America, supplementing the original Siberian-oriented migration across the Bering Strait.

    Dodecad K12b Oracle results:
    The GEDmatch version of Oracle may give slightly different results from Dienekes version. The GEDmatch version uses FST weighting in its calculations.

    So my hypothesis is incorrect then. Interesting. I would be interested to know the origin of these influences. Or are they present in Siberia too?

    They possibly are. One has to take with a grain of salt the label of those components. The Northern European component of Dodecad k12b, f.e, peaks in Northeast and Eastern Europe rather than in "Northern Europe".

    Hmm from what I read in a recent paper, the tiny South Asian" and "Southeast Asian" admixture actually has something to do with Austromelanesians like Papuans, Australian Aborgiines, Onge/other Andaman Islanders and Negrito populations rather than from actual modern day SE Asians who are a later population to the region.

    There are some R1b variants among natives of North American Indians which likely came from an Early European migration. (possibly Vikings)Some hypothesis says that some Oceanians have reached the coasts of South America, but We need more Autosomal DNA analysis on South Americans to fully discover their heritage.
