Symposium: Evolution in the dark: unifying understanding of eye loss

Symposium Description: The evolution of eye loss in subterranean, deep sea and nocturnal habitats has fascinated biologists since Darwin wrestled with it in On the Origin of Species. This phenomenon appears consistently throughout the animal kingdom, in groups as diverse as crustaceans, salamanders, gastropods, spiders and the well-known Mexican cave fish, but the nature, extent and evolutionary processes behind eye loss remain elusive. With the advantage of new molecular and developmental tools, eye loss has once again become the subject of intense research focus. The goal of this symposium will be to bring together a cross-disciplinary group of researchers working on the historic question, ‘how does eye loss evolve in the dark?’. The symposium will showcase new progress made in the diverse fields of molecular biology, phylogenetics, development, comparative anatomy, neurobiology, ecology and behaviour in a wide range of study organisms and habitats, and encourage the exchange of ideas between participants and discuss future directions for the field of eye loss.
