Brief synopsis of current research:
My students and I use comparative and experimental studies of marine invertebrate morphology and ecology to address issues of evolutionary significance: origin and maintenance of morphological diversity, ecological and historical context of adaptation, and costs and benefits of functionally significant traits. We focus either on diverse groups (molluscs or crustaceans) or on groups pivotal to theories of higher taxon origins (hemichordates). Because of its central place in the debate over mechanisms of evolution, our ongoing research focuses mainly on the evolution of innovations. We are examining three well-defined and conspicuous morphological innovations:
1) bilateral asymmetry in metazoans in general and crustacean claws in particular,
2) shell-loss and carcinization in lithodid crabs, and
3) gill slits in hemichordate worms.
