       | about

         | enclaves of Occitan speakers in far southern Italy would show
         | up.

         | That said, this is a point of contention that even the authors
         | of the paper allude to:
         | 
         | "The most principled approach is thus to build ancestry models
         | in which source and 'outgroup/reference' populations are older
         | than, or at least contemporary with, the target genome or group
         | that we are trying to model. However, this has been
         | challenging, due to the limited statistical power offered by
         | the thousands-fold lower sample sizes and reduced sequence
         | quality of ancient genomes"

       | Do I get this right: genes were flowing from Scandinavia down to
       | mainland Europe in the first half of the first century (i.e.
       | before the Vikings, are they talking about the ancestors of the
       | Goths and Vandals, for example?) and it reversed direction during
       | the Viking period?? Isn't that quite the opposite of what was
       | expected?
       | 
       | Iron age British ancestry being found in Ukraine with Viking
       | graves also sounds really fascinating.

         | scandinavia and other viking held areas because they would
