Tollense Valley Bronze Age battle field, standardized PCA-results

Using the same standardized data we have the following PCA plot, which differs from what we see on plots made using only partly overlapping SNP sets.  I don't see any reason to use Mediterranean samples, because of the small SNP number of some samples.  What we see in general on the plot is that most ancient samples  fall between Germans and Poles.  We see also that Finns, Russians, Poles and Norwegians show genetic drift.  The most Polish ancient sample is WEZ56 and WEZ54 falls inside the British cluster.  Samples WEZ39, WEZ40 and WEZ51 fall somewhat closer Finns, being still Central European. WEZ56 is the most Polish sample in the original study graphics too.

  1. Awesome stuff. Some are saying the warriors come from a people who contributed both to Germany and West Slavs. Does that sound plausible to you?

  2. I think so, but I don't know can we use linguistic definitions. The South-European admixture they show is another question. Definitely none of them were South- European, but many of them show on PCA plots more South-European trace than modern Central or Western European people, because PCA show more tendency towards minor affinities, in this case towards old one. WEZ48, WEZ16, WEZ54, WEZ57, WEZ63, WEZ35, WEZ74, they all show South European trace comparable to French, but then also more northern or eastern affinity more than Frenchmen. They simply looks somewhat different to modern Central-Europeans.
