For them to have evolved does not mean they had to have wisdom & knowledge. If you understand the principles of science, biology, and evolution (as you say you do), then you would know that.
They did not change their own functionality. The next generation was slightly (or more) different, giving them an advantage.
Solitary, I fully realize they don't have wisdom or knowledge. I do understand the principles of science and biology. A photocell operates from simple stimulation of light on nerve receptors, a human eye works on a principle of projected images to the retina, through a cornea and lens, and regulated by the iris. They are two entirely different types of function. There is no "evolutionary" process which would have produced this result. Why? Because, evolution doesn't have knowledge and wisdom! The photocell eye doesn't "know" it needs a cornea, lens, retina, etc... evolution doesn't "know" it needs to develop these components! So, without "wisdom and knowledge" the eye couldn't have "evolved" from a primitive photocell to a complex human eye, it's not possible according to Darwin.
Evolution can explain mutations, it can explain adaptations, it can theorize how a flipper became a limb, or how a bear develops a white coat to adapt to the arctic conditions. These are things that could potentially change within a species as part of natural selection, through an evolution process, because there is a fundamental connection in functionality and a purpose for the adaptation, vital to the species existence. The theory you are presenting for the eye, doesn't meet this criteria, because the human eye is far more complex and operates completely different from a simple photocell eyespot, and the eyespot doesn't possess knowledge and understanding to be able to make the kinds of changes required for it to become a human eye. It's impossible!
