Marine Speciation

Recent evolutionary radiations such as Darwin’s finches, East African cichlids or Heliconius butterflies have served as model systems to understand how novel variation and new species arise. These systems, clearly in the early stages of divergence, have stimulated research into the behavioral, ecological, and genetic bases of reproductive isolation that have arguably transformed our understanding of the origins of biodiversity. However, no analogous classic radiation comes to mind in the largest ecosystem on earth, the ocean. The overarching goal of our research is to develop the hamlets (Hypoplectrus spp, Serranidae), simultaneously hermaphroditic reef fishes from the wider Caribbean, into a model system for the study of marine speciation.
