Re Ashkenazi DNA - there’s an old Scientific American in a closet somewhere, that touched on this. Mostly it dealt with Mitochondrial DNA and humanity’s spread from Africa, but one little side box mentioned European Jews as a special case. I never would have guessed lactose intolerance was ~5% for Northern-Europeans, but like 70% for the European Jewish population. It’s very indirect evidence indeed, but the authors and I would have guessed at more inter-marriage (or other ways to intermingle DNA) than that genetic quirk would allow.
