But in the early days of life on this planet random mutation and natural selection stumbled upon a key molecule in the photosynthesis process, chlorophyll, that just happens to be green and it works OK, not perfectly but OK. In Evolution you don't have to be perfect you just have to be better than the competition. And once Evolution started to go down the chlorophyll path it soon became committed and it became virtually impossible to backtrack and look for something better than chlorophyll.
