Integrative analysis of a specialized metabolic pathway across multiple non-model species illustrates mechanisms of emergence of chemical novelty in plant metabolism.

A nightshade family gene cluster creates phenotypic novelty in trichome defensive metabolites via evolution of lipid metabolic enzymes.

A wild tomato species adopts local fruit color via introgression from an endemic relative, during its invasion onto the Galápagos Islands.

Neotropical outstanding biodiversity emerged from sustained rates of species accumulation over time, although, for some periods, tetrapods were less successful than plants in keeping pace with a changing environment.
