Review: The evo-devo of plant speciation

Speciation events result from a combination of molecular, environmental and stochastic (random) factors. Several models developed in the last 150 years help to explain how species emerge, but more recently evolutionary developmental biology (evo-devo) approaches give us tools to decipher plant speciation. In this review, Fernández-Mazueco and Glover show us the available evidence, from macro- to micro-evolutionary scales, of why plants are excellent study systems of speciation. They discuss how an integrative study of intra- and inter-specific variation in polyploidy, morphology, phenotypic plasticity, epigenetic inheritance, etc., could shed light in evolution of new species. This is a nice piece of literature for discussing with students! (Summary by Gaby Auge) Nature Ecol. Evol.  10.1038/s41559-017-0110
