A new study of divergence in freshwater fish provides strong evidence of rapid, temperature-mediated adaptation. This study is particularly important in the ongoing debate over the extent and significance of evolutionary response to climate change because divergence has occurred in relatively few generations in spite of ongoing gene flow and in the aftermath of a significant genetic bottleneck, factors that have previously been considered obstacles to evolution. Climate change may thus be more likely to foster contemporary evolutionary responses than has been anticipated, and I argue here for the importance of investigating their possible occurrence.
一项关于淡水鱼类分歧的新研究为快速的、受温度介导的适应提供了强有力的证据。由于在持续的基因流和重大遗传瓶颈之后，尽管发生了分歧，但进化反应的程度和意义仍在持续争论中，因此这项研究对于解决这一争论尤为重要。这些因素以前被认为是进化的障碍。因此，气候变化可能比预期更有可能促进当代进化反应，我在这里主张调查它们可能发生的重要性。
