We do not see with the eyes but with information gathered by the eyes and processed in the brain /mind. An organism can't make use of a mutation that gives it sensory information as for instance photosensitive cells as to have an advantage over another organism without that mutation, if it has not already developed a brain with the capacity to process that information. The brain has to have developed first in anticipation of the eye developing. This means that a brain with the capacity for processing signals from a photosensitive cells develops in anticipation for such an event by natural selection? We are not talking here about one or two chance mutations that might be useful sometime later but a capacity to give some degree of sight to an organism no matter how slight. I cannot see how this is possible by natural selection. What do you think?
