Consistent individual differences in behavior (i.e. animal personality) are often correlated within what are known as behavioral syndromes but the potential of animal personality and behavioral syndromes to affect evolutionary outcomes is unknown. Here we show that geographically isolated populations of field crickets (Gryllus integer) exhibit a genetically conserved syndrome structure and that the degree of genetic constraint was consistent among populations. Moreover, divergence among populations was constrained by this genetically conserved behavioral syndrome. Our results demonstrate that a conserved genetic architecture shaped the evolutionary trajectories of populations in disparate environments.
