The origin of novelty is one of the central questions of evolution. We seek to understand, in general, the relative contributions of different mechanisms – gene co-option, gene duplication and loss, regulatory and protein sequence changes – to the evolution of different kinds of traits. Our research has focused on the evolution of morphological traits in animals, and more recently, on biochemical novelties such as the evolution of snake venom.
