It is interesting to look at the various eyes found in nature today. There seems to be a gradation of eyes but these eyes have evolved independently. "Salvini-Plawen and Mayr tallied all the independent events and estimated that the lineages leading to living animals have invented eyes somewhere between 40 and 60 times."(Raff, 1996) These events have been driven genetic events of the type that Dr. Rosenberg mentioned as macroevolutionary changes.
