Molecular Insights into the Eye Evolution of Bivalvian Molluscs

However, recent molecular genetic evidence points to a common genetic program for eye development in all eye-bearing organisms. Based on these findings it was proposed that the various eye types found in Metazoa derive from a common ancestor prototype eye. The author, Lukas Keller, reviews the various eye types found in the animal kingdom and the recent molecular data that lead to the hypothesis of a monophyletic origin of the eye. His own research on eye selector and opsin genes in bivalvian molluscs further strengthen the idea that all animal eyes derive from a common ancestor eye. Furthermore, his results suggest a functional role of Pax-6 and Six1\/2 genes in the gills of the bivalves Arca noae and Pecten maximus and raises the interesting question whether these genes are implicated in the establishment of the chemosensory field.","image":"https:\/\/c4-static.dodax.com\/v2\/180-180-138180218_YGE98-png","url":"https:\/\/www.vergleiche.ch\/unterhaltung\/product\/molecular-insights-into-the-eye-evolution-of-bivalvian-molluscs\/","min_price":93.900000000000005684341886080801486968994140625,"low_price_merchant_id":70254503,"deeplink":"https:\/\/www.awin1.com\/pclick.php?p=41013095042&a=401125&m=13971&pref1=9783838104904","ean":9783838104904,"brand":"undefined"}
