A huge and exciting new study has just been published in Proceedings of the National Academy of Sciences (PNAS) on human genetic variation in Scotland and the Isles - but really it looks at variation across Britain and Ireland (and into Iceland). The study significantly increases the number of testers and geographic resolution of different genetic groups. I am still digesting the results - and implications for the Sproul DNA Project. More on this later. For starters, at the end of this blog is a key dendrogram and map from the study.
