Tracing Histories of Polyploidy, Admixture, and Diversification in a Hawaiian Plant Radiation through Genomic Analyses

In this study we use genomic data to detail the evolutionary history of the Hawaiian endemic mint radiation. Evolutionary radiations are characterized by rapid speciation with little genetic differentiation, in which genetic markers can leave many questions unanswered. Using genomic data, we were able to characterize the polyploid and hybrid origin of the lineage and also characterize hybridization among species and in a hybrid swarm.
