WOOD HOLE, Mass. – Many crustaceans, including lobsters, crabs, and barnacles, have a cape-like shell protruding from the head that can serve a variety of roles, such as a small cave for storing eggs, or a protective shield to keep the gills moist. This shell (carapace), it has been proposed, did not evolve from a similar structure in a crustacean ancestor, but emerged de novo (or suddenly) through the rather random co-optation of genes that also determine insect wings. However, in a new study from the Marine Biological Laboratory (MBL), Research Associate Heather Bruce and Director Nipam Patel provide evidence for an alternative view: The carapace, along with other plate-like structures in arthropods (crustaceans, insects, arachnids, and myriapods) all evolved from the lateral toe lobe in a common ancestor. This evidence underpins their proposal for a new concept of how new structures evolve – which suggests that they are not so new. A study of the carapace of Daphnia crustacea...
