…biological energy via oxygenic photosynthesis. Cyanobacteria originated in a freshwater or terrestrial environment, and first appeared in the middle Archean eon. They are probably the most numerous taxon to have ever existed on Earth. The name "cyanobacteria" (from Ancient Greek κύανος (kúanos) 'blue') refers…
