Nature Communications, Published online: 08 May 2026; doi:10.1038/s41467-026-72784-z Complex spatial structure and environment heterogeneity shape the evolution of natural populations. This study shows that environment heterogeneity can foster the quick fixation of beneficial mutants in populations structured into demes on a graph.
