Please remember when you study natural selection you have to factor in geological time scales.
Of course, but whether the time scale is four million or four billion years, change needs to happen. Apparently, the eye lens could have evolved in less than half a million years. If life started in the oceans, then what tools did blind nature have to cause change? There was the tide to swish chemicals around, sunlight, lightning, hot and cold water, an increase in oxygen levels. These tools seem very crude and inadequate to make eyes and a skeletal system for fish.
According to Nisson, random mutation had to make over 1800 improvements to the design of an eye lens. But what tools did random mutation have to come up with these improved incremental modifications each time? Natural selection had to work 1800 times to select the best modification. Failures happened along the way, but the end result was still 1800 wins.
