The title is tongue in cheek. But I have been noting with interest Dienekes' trial runs with TreeMix. With it he has discovered a very peculiar admixture event, at least as determined by the software. The results are below, with my clarifying labels:
Basically the software seems to be implying that there has been gene flow into the Yoruba of West Africa from from populations related to the Basque & Sardinians. The most plausible explanation for this would be that this migration event was ancient, so that later admixtures of European populations are not reflected. Whether you believe that the Basque/Sardinians are Neolithic or pre-Neolithic (i.e., that they derive from Holocene settlers, or derive from Paleolithic European substrate), it is probably true that they have a relatively long period of residence in Western Europe.
