Most species are distributed across geography, and so can develop regional differences in different parts of the range. These may often be as a result of natural selection, and the geographic scale on which different solutions to evolutionary problems can appear -- the spatial resolution of adaptation -- is determined by a balance between migration, selection, and availability of genetic variation. I will describe some recent work to develop appropriate stochastic models for this problem, as well as progress using georeferenced whole genomes to fit a geographically explicit population model. A recurrent theme is the use of diffusion theory to describe the spatial motion of lineages.
