In a previous paper, Dingle (2003) considered the possibility of gene reactivation leading to the re-appearance of eyes in certain blind ostracod taxa after sightedness had been lost in lineages several million years earlier. These observations were based on two marine genera found at Marion Island in the Southern Ocean (Eocene–Recent Poseidonamicus Benson, and Campanian–Recent Dutoitella Dingle) that have evolved numerous deep-water species that were/are blind. The discovery of Recent, sighted, shallow-water forms led to the suggestion that adaptive pressure from the advantages of sightedness had resulted in the reactivation of genes that allowed an evolutionary advantage to be...
