The chunkcount heatmap show much the same as in previous analysis but the new cluster seen in the Fennoscandia analysis also appear here. Chunkcounts is the total number of identical and related segments of DNA between any individual. The intensity of the colors on the heatmap and the closeness in the tree branch indicate relatedness to other individuals or groups.

The PCA overview of Europe appears to be better than previous analysis by using superindividual grouping for "others". We can now for example see a clear differentiation between Finns and Saamis in dimension 3 horizontal and dimension vertical 4. The differentiation in dimension 4 appears to be that Saamis pull to the same level as the Basque and Sardinians in this axis.

The PCA components presented in geographical heatmaps:
Dimension 1 - external peaks in Finns. Opposite Spanish, Sardinians and Romanians. What source "Others" is is not known but appears to be close.
Dimension 2 - external peaks in Albanians, Mordovians, Vologa Russians and Saamis. Opposite Scandinavians. May suggest a non-European influence that have arrived far north and far south into Europe or/and foundereffect among Scandinavians.
Dimension 3 - internal peaks in Finns and Saamis. Opposite Basque and Sardinians. May reflect expansion of agriculture to Europe.
Dimension 4 - internal peaks in Lithuanians, Mordovians, Belorussians, Ukranians. Opposite Basque Sardinians and Saamis. May reflect Eastern European expansion and/or foundereffect. The ancestry sharing along the Western European shores from Iberians to the Saamis may suggest old coastal migrations from the south to the north.
Dimension 5 - internal peaks among Scandinavians and Saamis. Opposite Basque, Sardinians, Spanish and Finns. This may show an agricultural expansion from South-East Europe to Finland.
Dimension 6 - internal peaks among Basque and secondary Saami. Opposite Sardinians. May suggest a common autosomal link between Saamis and Basque.
Dimension 7 - internal peaks among Saamis and secondary Sardinians. Opposite British and Vologda Russians. Appears specific to Saamis as rest of Europe appears quite uniform except for the Sardinians.
