title: Natural selection: it's a many-small world after all.
abstract: Understanding adaptive phenotypic change and its genetic underpinnings is a major challenge in biology. Threespine stickleback fish, experimentally exposed to divergent semi-natural environments, reveal that adaptive diversification can happen readily, affects many traits and involves numerous genetic loci across the genome.
