    Haplogroup R1a distribution in Iberia

    I was taking a look throughout Eupedia's table, and I have seen also plenty of studies, and something that caught my attention is the complete absence of haplogroup R1a in Basque, where singletons such as J1, T and even Q have popped up, yet not a single R1a has ever been sampled. On the other hand we see the Cantabrians having a peak in R1a, with 8.5% for the whole regions but up to ~40% in the Pasiegos area. It seems R1a is found at fairly low frequencies throughout Iberia. So could it be that it is a byproduct of the Germanic invasions to Spain, if so, this would suggest nearly zero impact of the Visigoth on the Basque population, yet we do find I1 in Basque though at incredibly low frequencies, and it has popped up only once.

    Are the Visigoth supposed to be R1a?

    It's a possibility, as far as I know they came from Eastern Europe.

    Some of their warrior should be r1a.

    There are quite many possibilities for explaining how R1a arrived in Iberia. But I would be interested in knowing to which kind of subclades Spanish R1a carriers belong if some of them carry Z93 some of it could be brought to Iberia by Alans/Sarmatian mercenaries or even by Arabs or Jews (very speculative). But I guess that most of is a byproduct of Germanic invasions (Visigoths were East Germanics and certainly richer in R1a than most other Germanics) and maybe of slave trade (Slavs or Turks). Many (mostly Turkic) Slaves were recruited as warriors in muslim kingdoms and in some cases they even became quite powerful but I don't know if there were so many slaves of Turkic or Slavic origin in Iberia.

    Wow 40% in Pasiegos that is quite impressive for West Europe/Iberia. I wonder how many people were tested there it could be just a small sample so maybe it is not representative but in small areas founder effects or even small migrations can dramatically change the distribution of various Y-DNA lineages . But I am also impressed that 8,5 % of men in Cantabria carry R1a ( in this case certain the byproduct of Germanic invasions in my opinion)

    We need the proper R1a Iberian sequence and position of SNPs and the frequency in the population.
    One case is here but I don't know the frequency and region.

    Hm, R1a-CTS6, that's rather interesting to say the least...

    My Haplogroup designation is R-Y57 Z93>Z94>Z2124>Z2122>Y57*-x (Big Y needed) I am kit 447312 in the FTDNA R1A1 Project, page 11. I tested my YDNA in 2015 and have had 2 matches at the 37marker level in FTDNA. One is a Mexican match at a genetic distance of 1 and the other is a Portuguese match at a genetic distance of 4. There is not much information on the web about my current subclade. Any opinions, information or insight would be greatly appreciated.

    We can find several Europeans and one Peruvian at Y57 https://www.yfull.com/tree/R-Y57/
    If you have contact with your FTDNA matches ask them if they also have other different matches.

    Hi Jose.

    Given the widespread (but still somewhat limited and more westerly in comparison to many other Z93 subclades) distribution of Y57, I think that this clade is connected with European Scythians and very likely also Alans.

    Taking into consideration their migratory route, ties with Germanic tribes and modern distribution of Y57 (mostly Europe and West Asia/Caucasus) it is plausible that many Europeans who tested Y57 are ancestors of those aforementioned nomads who assimilated into Germanic cultures at some point of history.
