  abstract =     "The impact of population structure on evolving
                 populations is difficult to study. Populations broken
                 up into groups of organisms and connected by low levels
                 of migration will experience different types of
                 geneflow than normal unstructured populations. Various
                 studies, spanning decades of research, have lead to
                 seemingly contradictory conclusions. Some point to
                 population structure as a means to improve adaptation,
                 others argue that population structure hinders
                 evolution. We investigate how population structure
                 impacts the evolution of complex functions in
                 environments with limited resources. We find that
                 structured populations with limited resources tend to
                 evolve complex functions at a higher rate than
                 unstructured populations, across a broad range of
                 migration rates. This suggests that population
                 structure may have an important impact on evolution, in
                 both sexual and asexual populations, at least at
                 certain migration rates.",
