“…However, studies based on molecular biology and evolution have revealed that, even though the evolutionary processes of different types of eyes seem different, the molecular basis is shared among the various eye types and they arose by divergent evolution (Nilsson 2004;Serb and Eernisse 2008). These phenomena have often been explained by the concepts of convergent and divergent evolution.…”

There are several types of eyes in morphology such as camera eye, compound eye, mirror eye, and single lens eye, and all the eye types have been evolved from the same origin, the prototype eye. Even though there are conserved genes and networks in the eye evolution, little is known about what kinds of genetic basis have been contributed to the eye diversification. It is essential for discovering genes for the morphological diversification to develop a platform of genomic and transcriptomic comparison among species. We, therefore, developed microarray that cover the genes related to development, function, and structure of molluscan eye, as an example, for the evolutionary genomic studies.

“…Coleolid cephalopods have rhabdomeric (microvillous) photoreceptors in a camera-type eye that optically functions in a similar manner to the vertebrate eye, making the cephalopod eye a famous example of convergent evolution (Packard 1972; however, see Serb and Eernisse (2008) and references within for alternative views). Specifically, the cephalopod eye resembles an all-rod elasmobranch eye with similar optics, speed, sensitivity, and resolution (Packard 1972).…”

Several invertebrate systems have been developed to study various aspects of the eye and eye disease including Drosophila, Planaria, Platynereis, and most recently, the cubozoan jellyfish Tripedalia; however, molluscs, the second largest metazoan phylum, so far have been underrepresented in eye research. This is surprising as mollusc systems offer opportunities to study visual processes that may be altered by disease, vision physiology, development of the visual system, behavior, and evolution. Malacologists have labored for over a century as morphologists, systematists, physiologists, and ecologists in order to understand the structural and functional diversity in molluscs at all levels of biological organization. Yet, malacologists have had little opportunity to interact with researchers whose interests are restricted to the biology and development of eyes as model systems as they tend not to publish in the same journals or attend the same meetings. In an effort to highlight the advantages of molluscan eyes as a model system and encourage greater collaboration among researchers, I provide an overview of molluscan eye research from these two perspectives: eye researchers whose interests involve the development, physiology, and disease of the eye and malacologists who study the complete organism in its natural environment. I discuss the developmental and genetic information available for molluscan eyes and the need to place this work in an evolutionary perspective. Finally, I discuss how synergy between these two groups will advance eye research, broaden research in both fields, and aid in developing new molluscan models for eye research.

“…Parallel evolution (e.g., Serb and Eernisse 2008) can be defined as the independent evolution of similar biological traits in at least two different lineages having similar phenotypic trajectories driven by common (developmental) constraints. Parallel evolution is often confused with convergence (Webb 1994) since both can result in taxa with highly similar characters, but the two concepts remain distinct (Serb and Eernisse 2008) even if there may be a continuum between parallelism and convergence (Gould 2002;Donoghue 2005).…”
