Cover Story: We tested for congruence in mechanisms of microevolution and macroevolution by comparing patterns of life history divergence among three closely related species of the livebearer genus Brachyrhaphis (Poeciliidae). Within B. rhabdophora, populations occur in either predator or predator-free environments, and sister species B. roseni and B. terrabensis are similarly segregated. Size at maturity, clutch size, and offspring size all diverged according to predation environment, and differences were amplified through evolutionary time. Variation observed among nascent species is a good predictor of variation among established species. Macroevolution in these species can be understood as an accumulation of micro-evolutionary changes. View this paper
