  • Rapid population growth and dispersal foster polyploid species establishment.
  • Introgressive hybridization enhances the persistence of polyploid species.
  • Multiple independent origins of polyploid lineages promote their diversification.
  • The extinction of diploid species favors the production of autopolyploids.
