重复的进化可以提供对促进适应新的或变化的环境的机制的洞察。在这里，我们研究适应海拔在两个热带蝴蝶，Heliconius erato和H。melpomene，它反复和独立地适应了安第斯山脉两侧的山地栖息地。我们对518个来自海拔样带的全基因组进行了测序，发现许多区域在高地（~ 1200 m）和低地（~ 200 m）种群之间存在差异。我们重复的遗传分化在物种内的重复种群，包括异地比较。相反，这两个物种之间几乎没有分子平行性。通过对五个近亲进行取样，我们发现物种内鉴定出的大部分不同区域都来自高海拔专业物种的常设变异和假定的适应性渐渗。总之，我们的研究支持的作用，常设的遗传变异和基因流从独立适应的物种，促进并行本地适应环境。在这里，作者研究了两种热带蝴蝶的518个全基因组对海拔的适应。他们发现物种内重复的遗传分化，这些物种之间几乎没有分子平行性，以及密切相关物种的渐渗，得出结论认为，持续的遗传变异促进了平行的局部适应。
Repeated evolution can provide insight into the mechanisms that facilitate adaptation to novel or changing environments. Here we study adaptation to altitude in two tropical butterflies, Heliconius erato and H. melpomene, which have repeatedly and independently adapted to montane habitats on either side of the Andes. We sequenced 518 whole genomes from altitudinal transects and found many regions differentiated between highland (~ 1200 m) and lowland (~ 200 m) populations. We show repeated genetic differentiation across replicate populations within species, including allopatric comparisons. In contrast, there is little molecular parallelism between the two species. By sampling five close relatives, we find that a large proportion of divergent regions identified within species have arisen from standing variation and putative adaptive introgression from high-altitude specialist species. Taken together our study supports a role for both standing genetic variation and gene flow from independently adapted species in promoting parallel local adaptation to the environment. Here, the authors study adaptation to altitude in 518 whole genomes from two species of tropical butterflies. They find repeated genetic differentiation within species, little molecular parallelism between these species, and introgression from closely related species, concluding that standing genetic variation promotes parallel local adaptation.
