Continuing my previous testing method I tried to find out if it is possible to make any conclusion about where the IE-language family is from. Did it come from east to Central Europe, from Middle East to South Europe or via another southern route? To analyze it I made two tests, dividing at first the data between two major Bronze Age Central European cultures using Corded Ware and Bell Beaker samples.
It looks like there is nothing common between Central and South Europeans explaining the supposed linguistic root by Central European cultures. Non-IE speakers, Basques and Finns, are placed between those two major IE-groups. Because plotting the difference between Corded Ware and Bell Beaker samples looked however logical in a sense of place in geography I brought those groups together and used Anatolian Neolithic samples on the second axis, trying to reveal how the early farmer ancestry changes the picture.
The result broughtnot Central and South Europeans closer each other, but still the question remains: if IE-languages wer brought to Central Europe via East Europe how we explain the lack of distinct Corded Ware and Bell Beaker drift ainfluence in the south? It looks more like we have in Central Europe a strong southern gene impact instead of any strong northern influence in the south.

Maybe it is not yet clear who are those Local and MostCW Finns. At first they are on European, Eurasian and world level PCA plots almost in a same position, there is no distinct trend separating them towards any other Europen or Asian populations. Both groups act very similarly on PCA-plots constructed of present-day populations, but they clearly differ in wide genome tests and tests implying genetic drift, such as Dstat.
