Walser communities that are geographically or topographically remote from the homeland and from other communities showed higher genetic differentiation, likely as a consequence of genetic drift. The genetic similarity among the other communities might be explained by the relatively short divergence time, coupled with cultural and economic exchange among the Walser and Walser-homeland communities.
