It looks just as advanced as a modern compound eye. This is what we should expect if the time it takes to evolve an eye is negligible by geological standards. A central message of this chapter is that eyes evolve easily and fast, at the drop of a hat. 7 Bear in mind, that there isn't a single fossil with a partially developed eye to support his belief that eyes evolve. But now he has an excuse for lack of positive evidence.
Eyes evolve so rapidly that the chances of finding a partially developed eye is negligible.
Computer Simulations of Evolution Dawkins partially bases his conclusions on some computer programs that he believes simulate evolution. The first such program he published was the Blind Watchmaker, which is described in a previous book with that name. His two new derivative programs he describes in Climbing Mount Improbable are the NetSpinner and Blind Snailmaker. NetSpinner simulates the evolution of spider webs. Blind Snailmaker simulates the evolution of sea shells.
