Abstract:
Genetic exchange between independently evolving lineages may give rise to the formation of new taxa, and hypotheses for this have been derived from species with intermediate phenotypes, when compared to potential parental species. Goulet-Scott and collaborators (2021) evaluate such a hypothesis in a wildflower species complex by integrating genomic and trait information. They find no support for hybrid speciation, despite detecting signatures of genetic admixture in some individuals resulting from interspecific gene flow in a hybrid zone.
