  • I2a - "mega thread"

    I thought I'd start what I hope to be the "main" I2a discussion thread.

    A couple of thread topics for discussion that I personally would like to explore are:

    -- glacial refugium (Iberian penninsula, Dinaric alps, Black sea coast, Caucasus region, Anatolia, etc.)

    -- latest archaeological findings as they relate to European, Eurasian Steppe, and Anatolian genetic testing. Let's talk facts, not run-on speculation based on poor/ brief/ questionable historical accounts.

    -- your earliest ancestor's country/state/city of origin.

    Also, what is your terminal SNP?

    If you feel you need more testing, experts like, Bernie Cullen, Zdenko Markovic, and Lawrence Mayka can hopefully chime-in and guide you.

    Most importantly, DO NOT SPEND A RED CENT until you get advice from these guys. I can't tell you how many hundreds of dollars I saved due to the good advice of these fine gentlemen.

    Paternal: I-A2423 (tested at ySeq.net)

    I2a2 'Dinaric' L621 > CTS10228 > S17250 > BY128 > Z16971 > A2423 (I-A2423)

    The average age of A2423 is 918 years (based on Big Y results to date)

    *********************************

    Maternal: H7c3

    H7 is an uncommon branch of haplogroup H and is found at low frequencies in both Europe and the Near East. Its age is estimated to be around 15,000 years.

    *********************************

    "MyOrigins" (autosomal DNA):

    Eastern Europe: 58%
    Southern Europe: 16%
    Western & Central Europe: 16%
    Finland & Northern Siberia: 6%
    Asia Minor (Anatolia): 3%

    *********************************

    Family Finder Matches (Y-DNA) spread all over the map, which would explain "MyOrigins" above.

    Major Clades of my autosomal DNA matches are:

    R1b -- 16 matches
    R1a -- 11 matches
    I2a -- 8 matches
    I (old I) -- 2 matches
    J2 -- 6 matches
    E1b -- 2 matches
    G -- 2 matches
    N -- 1 match
    T -- 1 match

        Another fantastic, easy-to-read explanation of the origins of ancient Europeans. A must read for all I2 folk!

          from the article above:

          "The man from Kostenki shared close ancestry with hunter-gatherers in Europe—as well as with the early farmers, suggesting that his ancestors interbred with members of the same Middle Eastern population who later turned into farmers and came to Europe themselves. Finally, he also carried the signature of the shadowy western Asians, including a boy who lived 24,000 years ago at Mal’ta in central Siberia. If that finding holds up, the mysterious DNA from western Eurasia must be very ancient, and not solely from a wave of nomads that entered Europe 5000 years ago or so, as proposed by researchers in September."

            An even better article containing all the elements noted in other articles:

              Here is YFull's haplotree for I-A2423 (also called I-Y12911). YFull offers two different dates:

              Formed 1800 ybp - This branch began to diverge from its parent/siblings about 1800 years ago.

              TMRCA 750 ybp - The examples examined by YFull have a Time to Most Recent Common Ancestor (TMRCA) of about 750 years.

              These are clearly very rough numbers, because YFull has only identified one reliable defining SNP (so far) for the clade--an unrealistically low number if the clade was really gestating for 1050 years. Perhaps YFull is waiting for a third example before committing to a full list of common SNPs.

                EDIT: you are correct. I went back to look and the dates have indeed changed: 761 ybp

                Rough, but certainly young.

                  When you think we'll see the full list?

                    My suggestion (not based on any specific knowledge) is that YFull may be waiting for a third example of your subclade. Some SNPs that look iffy on only two people (e.g., if the number of reads is low for both) may look more solid if a third example arrives.

                      Several I2a Project members that are I-Z16971 positive, 3 or 4 of them, have tested negative for both I-A815 and I-A2423. One of them did the Big Y.

                              Sorry I'm late...

                              Forgot there were Forums here...oops.

                              I am I-P37.2*Alpine in the Old Terminology, I-A8689 now, and I-Y11949 at yFull. Very few connections here, the nearest TMCRA being 500 AD or so. Family is from Tai di Cadore, extreme northern Italy (Northern gateway for the Serene Republic, back in the day) with "possible ties" to Hvar, Croatia.
