Extensive introgression in a malaria vector species complex revealed by phylogenomics

Introduction The notion that species boundaries can be porous to introgression is increasingly accepted. Yet the broader role of introgression in evolution remains contentious and poorly documented, partly because of the challenges involved in accurately identifying introgression in the very groups where it is most likely to occur. Recently diverged species often have incomplete reproductive barriers and may hybridize where they overlap. However, because of retention and stochastic sorting of ancestral polymorphisms, inference of the correct species branching order is notoriously challenging for recent speciation events, especially those closely spaced in time. Without knowledge of species relationships, it is…
