I have been busy lately, but managed time to make a map of the EEF.
It would be nice to have some data for North Africa (besides Egypt) and Kazakhstan.
There is some conflicting data between the Lazaridis paper and the Eurogenes data based on the K13 admixtures. For example Lazaridis found that the Spaniards and the Basques had respectively 80% and 71% of EEF, while Eurogenes has 66-69% and 59%. Another odd difference is for Sardinians who have respectively 81% and 90%.
Percentages for other regions seem much more similar in the two sets of data though (e.g. Orcadians are both at 45%, Belarussians are at 40% vs 42%, Estonains at 32% vs 33%, Tuscans at 75% vs 78%, Hungarians 56% vs 52%, etc.).
I had to split some countries in two regions when the data was borderline between Lazaridis and Eurogenes. For example Bulgaria has values of 71% and 68%, Greece 79% and 82%, Scotland 39% and 45%...
I had to extrapolate a bit for some regions based on other data (Dodecad, Y-DNA).
There was no data for Montenegro or Macedonia, so I used to the same average as for Albania, Kosovo and southern Bulgaria.
In the Volga region, I assumed that the Tatars had more Neolithic farmer ancestry than their Chuvash and Mordvin neighbours, because they have considerably higher Near Eastern Y-DNA and Dodecad admixture.
In Scandinavia, individual data showed less than 40% of EEF in northern Sweden. Since the mountainous border between Norway and Sweden has substantial levels of mixed Saami-Scandinavian ancestry, it makes more sense if that region is more similar to northern Sweden.
I am not going to explain my reasoning for every single region, but nothing is arbitrary.
