Abstract

Homoploid hybrid speciation (HHS) has been historically considered as rare until the wide exploitation of genome sequences over the last few years. It is now widely believed that pervasive HHS was involved in the evolution of a wide range of plant and animal species (Mallet, 2007; Abbott et al., 2013; Sousa & Hey, 2013; Payseur & Rieseberg, 2016; Taylor & Larson, 2019). However, the majority of the reported cases of HHS have been deduced from analysis of sequence data only, while crucial evidence in support of such claims (including reproductive isolation between parental and hybrid lineages, and evidence of hybridization derived reproductive isolation) remains missing (Schumer et al., 2014).
