Climate change, urbanisation and exploitation of natural resources increasingly alter the environment, posingsignificant challenges for plants and animals. For species to adapt to such fast paced change, they will either need todraw on new genetic variation, which is likely to emerge very slowly, or on existing standing variation, which ispotentially very fast. Another possibility is that adaptive alleles will be acquired via hybridisation with closely relatedspecies, facilitating rapid adaptation through the re-use of existing adaptive variation. Repeated evolution of the sameadaptive trait offers unique opportunities to investigate genetic underpinning of rapid adaptation, ultimately informingus about the extent to which evolutionary responses to a changing climate might be predictable.

气候变化，城市化和自然资源的剥削日益改变环境，对动植物构成重要挑战。为了使物种适应如此快的节奏变化，它们要么需要绘制新的遗传变异，因此可能会非常缓慢地出现，或者对现有的静态变异，这是非常快速的。另一种可能性是，自适应等位基因将通过杂交与紧密相关的种类获取，从而通过重复使用现有的自适应变异来促进快速适应。 Sameadaptive性状的重复演变提供了研究快速适应的遗传基础的独特机会，最终将进化对气候变化的进化反应的程度告知可能是可以预测的。
