`::Wapondaponda, I think that these studies look only for similarities and what their words mean is ``we do not know which migrations happened we just see these similarities and think they must be caused by something interesting``. For example the Yoruba and Iberian might both have a lot of North African admixture. It is the same point I was making on the deleted article talkpage about Ethiopians. When ``admixture analysis`` clusters Ethiopians as a ``mix`` between Western Eurasians and ``Black Africans`` this does not mean the geneticists are saying that there were two source populations who were mixed together to give a cocktail. It means that they pretended something like this in their mathematical analysis, in order to get a perspective. Many different types of migrations can explain a single result like these. Obviously my point applies to Small Victory as well because what I am saying is that any attempt to take one admixture analysis and make big claims about directions of migrations is something we have to be very careful of.    `
