That was extremely interesting, John. Thanks. I'm not M222+, but I was
intrigued by your idea about a LGM refuge outside of Iberia. I have no
near-hits with anyone in Iberia and am 13 mismatches off the R1b modal. I
wonder if my own ancestors wintered the LGM someplace outside Iberia, like
in Italy or Anatolia, or perhaps near the Black Sea.
