Hybridization and speciation in angiosperms: arole for pollinator shifts?

The majority of convincingly documented cases of hybridization in angiosperms has involved genetic introgression between the parental species or formation of a hybrid species with increased ploidy; however, homoploid (diploid) hybridization may be just as common. Recent studies, including one in BMC Evolutionary Biology , show that pollinator shifts can play a role in both mechanisms of hybrid speciation. See research article {Link}
