You seem interested in eye evolution - I wasn't sure if you were aware of the high degree of genetic conservation in the eye - the gene Pax6 is considered the master regulator of eye development - the same in binocular human eyes as in the compound eyes of the fruit fly. The same gene, Pax6 activates rhodopsin genes in insects and lens crystallin genes of vertebrates.Recently, a group used the jellyfish Pax6 homolog (the jellyfish has surprisingly vertebrate-like eyes) in a study. Ectopic expression of the jellyfish Pax in fruit flies resulted in the formation of additional eyes:Role of Pax genes in eye evolution: a cnidarian PaxB gene uniting Pax2 and Pax6 functions - PubMedAn additional tidbit to combat the "eyes-couldn't-have-evolved" argument, since a single gene has the evolutionary plasticity to function appropriately during development of different eye systems.
