This chapter reviews the evolution of life forms that sense, respond to, and exploit various wavelengths of life-sustaining light. It discusses the photosensitive systems that have specialized in environmental information. This chapter shows that photosensory systems evolved to perform different functions. It draws the major environmental and biological events in the photo-biological history of the planet: prebiotic molecules, Archean bacterial photosynthesis, bacterial chlorophyll, protest symbioses and accessory pigments, invasion of land by embryophytes, and the revolution in image formation that occurred during the Cambrian period. It demonstrates that the color-signal overlap between species helped integrate ecosystems and, in turn, fostered progressively subtler color patterns, visual apparatuses, discriminating awareness, and analytic evaluations of what is illusion and what is real.

Keywords:   life, light, photosensitive systems, photosensory systems, prebiotic molecules, bacterial photosynthesis, bacterial chlorophyll, illusion
