How transcriptional gene networks operate during development and how they have emerged during evolution are two fundamental and interconnected questions in the evo-devo field (Davidson in The regulatory genome: gene regulatory networks in development and evolution. Academic Press, Amsterdam, 2006; Carroll in Cell 134(1):25–36, 2008). In this chapter we discuss the origin of the vertebrate eye from a common ancestor and its gene regulatory network (GRN). In an attempt to shed light on the evolutionary history of the vertebrate eye, photoreceptive structures present in our chordate sister groups cephalochordates (lancelets) and urochordates (tunicates) will be examined. Additionally, we summarize the still fragmentary information on the specification of visual organs in these chordate groups.
