    Icelandic R2-Y130994

    I sometimes find myself looking around yfull as a pass time and this sample intrigues me , it is an ancient sample from arond 1200 CE Iceland.
    https://www.yfull.com/tree/R-Y130994/
    from this study:
    https://www.nature.com/articles/s41586-020-2688-8
    Quite the odd y dna, how can it be explained, neolithic remnant ? CHG paternal origin?Descendent of a adventurous arab merchant ?
    Do any of you guys know how this man autossomal composition was ?
    I looked around the forum for this study but could not find it , maybe this individual was discussed on here before.

    There is also a somewhat interesting viking period L y dna https://www.yfull.com/tree/L-BY106184*/ , but this ones appears more clearly as a rare old european clade from neolithic times, so I would not be very surprised if he was just a normal swede, tho i would also be interested in his autossomals if you guys have it around.

    If I remember correctly there was one Imperial era sample from Italy with R2 as well

    Correct, that was sample R66. There is another R2 sample (R10337) from Tarquinia (151-3 calBC) who's autosomal DNA points to a Levantine origin. Like I tell people all the time when they ask me, not every Y-DNA finding is part of any single/specific migration event. Sometimes it is a handful of minor events over thousands of years. Needless to say, most folks don't like that answer

    People often lump all R2 folks into one group because the lineage is not that big and it loses most of the attention to the other R sibling. Also since most modern R2 comes from India, its often labeled as the South Asian lineage and not much focus takes place after that. In reality, there are lots of R2 lineages, and many of them have very ancient roots that most likely are not tied to India, rather, the other way around (Migration into India). The oldest samples of R2 are found among Neolithic Iranian samples, followed by samples among the BMAC civilizations, then we see younger R2 lineages (L295+) found in the Swat samples, so based on this data alone we see the migration pattern, and surely enough, the most dominant R2 branch in South Asia today is L295+.

    Anyhow, in regards to the Viking sample you speak of, it's only 800 years old. If you look at the branch that sample falls under, it was likely from the Middle East originally. But I remember seeing the autosomal data for it and it didn't seem out of the ordinary for when compared to the other Vikings. So odds are the R2 lineage for this individual existed in Europe for much longer time before 1200 AD.

    Which study is this from? This is a very ancient and way west beyond the Zagros, which is rather unusual for this lineage.

    Could be some backflow from the Central Asian steppe through e.g. Sarmatians of which some entered Germanic groups which in turn could have gone to Scandinavia. Like we do know that Gothic-related groups moved back to Scandinavia, sometimes even as elites and spread new innovations there.

    There is no evidence for that as not even one sample out of the hundreds we have from the Scythian horizon has R2. It didnt even have a strong presence in bronze age south Central Asia, and those clades arent even frequent amongst Sarmatians either. For example I cant recall any samples with J for instance although I dont doubt that some Sarmatians must've had it because we have a Ukrainian Scythian with J2. Same goes for other southern central asian clades. Sarmatian Y-dna seems to be overwhelmingly derived from Srubnaya-Alakul and Karasuk groups.
