During adaption to novel environments, organisms change multiple physiological and life history traits. In contrast to morphological divergence, the molecular genetic mechanisms underlying physiological and life history evolution in wild organisms is largely unknown. To address this question, I use the threespine stickleback (Gasterosteus aculeatus) as a model system.
