Hybridisation and Genome Duplication

Monkey flower hybrids reveal rapid speciation in introduced species. Human transport of plants and animals around the globe, whether accidental or not, is homogeneising the world’s biota. Hybridisation among previously isolated species of monkey flowers (Mimulus spp.)¬†from opposite sides of the American continent, has produced an array of sterile plants that are naturalised and widespread in the United Kingdom. Some of these hybrids have gone on to produce the most recent example of a new species evolving in the last 150 years: Mimulus peregrinus.
