Just a possibility on this. It is not so much the plant as the photosynthetic process which is relevent. A certain molecule, or complex of molecules could do the job and so survived, despite not being optimal as far as gathering sunlight went. A molecule which was optimal for using light and also optimally suited for incorporation into the structure of a plant, just never got started.

Sorry, that’s NOT a good answer. Surely plants have evolved to absorb the most abundant wavelengths in sunlight, which happens to be green/yellow. If leaves REFLECT GREEN then they have evolved to ABSORB BLUE and RED. What you have not considered is the possibility that the sun has not always had its current spectral distribution.

You will find there is evidence all around us that sunlight has changed. Start with your own eyes. The photopic curve shows that blue is our weakest colour and green our highest sensitivity. This is surely the opposite to what we need now – green being the most plentiful wavelength of this current Sun. Same with many animals and birds too. What has changed? Or did Nature get it wrong?
