How common is speciation-with-gene-flow? How much does gene flow impact on speciation? To answer questions like these requires understanding of the common obstacles to evolving reproductive isolation in the face of gene flow and the factors that favour this crucial step. We provide a common framework for the ways in which gene flow opposes speciation and the potential conditions that may ease divergence. This framework is centred on the challenge shared by most scenarios of speciation-with-gene-flow, i.e. the need for coupling among different components of reproductive isolation. Using this structure, we review and compare the factors favouring speciation with the intention of providing a more integrated picture of speciation-with-gene-flow.
基因流条件下的物种形成有多普遍?基因流对物种形成的影响有多大?要回答诸如此类的问题,需要了解在面对基因流时进化生殖隔离的常见障碍,以及有利于这一关键步骤的因素。我们为基因流阻碍物种形成的方式以及可能促进分歧的潜在条件提供了一个通用框架。这个框架的核心是大多数基因流物种形成情景所面临的挑战,即需要将生殖隔离的不同组成部分结合起来。使用这个结构,我们回顾和比较了有利于物种形成的因素,旨在提供一个更综合的基因流物种形成图景。
