Conclusion - the gradient of Yamna culture decreases from the East of Europe to the West. I'd like to check on the G25. Objective: as few intersecting components as possible. That would Yamna culture is not buried in them. That is ancient components Yamaha+EG+SG+EF and exotic for Europe of the impurity type of the Nganasans and the Yoruba and the middle East.

Northwestern Europeans appear to have the most steppe ancestry.

Northwestern Europeans appear to have the most steppe ancestry.

Northwestern Europe has the most Yamna culture in the celto-Germanic continuum. However, northeastern Europeans such as Latvians and Estonians have much more Yamna culture than northwestern Germans. The Sicilians are very few Yamna culture.. They're probably closer to Neolithic farmers.

You should definitely keep the penalty on though

No, still Estonians and Balts have less. The peaks of the Yamna component, Russian Kursk - 45, Irish - 44,2 and Norwegians - 43,4. Interesting combination

Here is a quote from your link

The main conclusion of the work is that representatives of the eastern and western parts of the culture of corded ceramics differ in the mitochondrial genome. Individuals in its eastern part (from Poland and the Czech Republic) are genetically close to individuals of the pit culture, while its western part (from Germany) is genetically different from the pit culture. Thus, there is a gradient of the steppe contribution, decreasing from east to west, probably reflecting the direction of the steppe migration. As for the Baltic part of the culture of corded stoneware, it is also genetically close to the pit culture, which means that intensive steppe migration reached the Baltic. The mtDNA data also shows that with increasing distance from the source of steppe migration, the proportion of genetic contribution from local neolithic farmers increases,

Interesting set, but I had to add simulated AASI to bring the fit distance down. Running me and wife's data in freeform nmonte3 runner:

Did you run this from the online freeform runner? If so, you are missing Yamna, which could mean that your "Step1" has "contains header"... if so, change to "no header" so that the tool can use the Yamna row.
