Limited evidence for a positive relationship between hybridization and diversification across seed plant families

Nora Mitchell & Kenneth Whitney
Hybridization has experimental and observational ties to evolutionary processes and outcomes such as adaptation, speciation, and radiation. Although it has been hypothesized that hybridization and diversification are positively correlated, this idea remains largely untested empirically, and hybridization can also potentially reduce diversity. Here, we use a hybridization database on 170 seed plant families, life history information, and a time-calibrated phylogeny to test for phylogenetically-corrected associations between hybridization and diversification rates, while also taking into account...
