Contemporary evolution is a growing issue in a world where human activity generates rapid changes to the environment and dramatically alters the selective landscape. Understanding how species respond to human impacts can help us address the challenge of mitigating our effects on natural systems. Linking phenotypic responses to their genetic or environmental basis and uncovering the genetic associations between different traits may help us predict how species will evolve in response to intense selection in the future. Here I use three important fish species to examine evolution in morphology, performance and behavior as a result of anthropogenic disturbance or artificial selection. In creek chub (Semotilus atromaculatus) and blacknose dace (Rhinichthys obtusus), I examine the effect of urbanization on body form and swimming kinematics. Changes in urban fish and the results of a laboratory rearing experiment suggest adaptive evolution to altered water flow regimes in urban streams. In zebrafish (Danio rerio), I test associations among morphology, performance, and behavioral syndromes. Artificial selection for behavior resulted in altered morphology and performance characteristics, indicating a genetic link between traits that are not usually considered together. Many species today may be undergoing undocumented evolution in human-altered habitats, and experiencing a wide range of unexpected trait shifts. A better understanding of contemporary evolution is needed to increase our ability to make informed choices and manage our impact on evolutionary processes.
