Figure 7

Developmental programs for opsin expression changes mapped on to the cichlid phylogeny. Tilapia shows a progression from a larval (pink) to a juvenile (violet) to an adult (blue) gene set. In contrast, cichlids from Lake Victoria and sand dwellers from Lake Malawi have a direct developing retina with only the adult gene set expressed throughout life. Rock dwellers from Lake Malawi have a neotenic progression, retaining the larval gene set or progressing slowly from larval to juvenile gene sets.
