Species and populations may adapt to climate change by microevolutionary processes. However, standing genetic variation can be insufficient for this to occur. An interesting new study of a system of rainbowfish species shows that intraspecific hybridization enriches gene pools with adaptive variation that may allow persistence in a changing climate.
物种和种群可以通过微进化过程来适应气候变化。然而，现有的遗传变异可能不足以实现这一点。一项关于彩虹鱼物种系统的有趣新研究表明，种内杂交丰富了基因库，带来了适应性变化，这可能使它们在不断变化的气候中得以生存。
