Abstract

Hybridization, or interbreeding between different taxa, was traditionally considered to be rare and to have a largely detrimental impact on biodiversity, sometimes leading to the breakdown of reproductive isolation and even to the reversal of speciation. However, modern genomic and analytical methods have shown that hybridization is common in some of the most diverse clades across the tree of life, sometimes leading to rapid increase of phenotypic variability, to introgression of adaptive alleles, to the formation of hybrid species, and even to entire species radiations. In this review, we identify consensus among diverse research programs to show how the field has progressed. Hybridization is a multifaceted evolutionary process that can strongly influence species formation and facilitate adaptation and persistence of species in a rapidly changing world. Progress on testing this hypothesis will require cooperation among different subdisciplines.

杂交在物种形成和持续存在中的作用。
杂交或不同类群之间的杂交传统上被认为是罕见的,对生物多样性有很大的不利影响,有时会导致生殖隔离的破坏,甚至导致物种分化的逆转。然而,现代基因组学和分析方法表明,杂交在生命树上一些最多样化的支系中很常见,有时会导致表型变异性的迅速增加、适应性等位基因的导入、杂交物种的形成,甚至整个物种的辐射。在这篇综述中,我们确定了不同研究项目之间的共识,以展示该领域的进展情况。杂交是一个多方面的进化过程,可对物种的形成产生重大影响,并促进物种在瞬息万变的世界中适应和生存。要在验证这一假设方面取得进展,需要不同分支学科之间的合作。
