    Early photosynthetic life likely began as bacteria in similar environments.  They then introduced oxygen into the atmosphere which now supports a wide array of animal life.  Oxygen is readily consumed by a reducing atmosphere and exposed rock.  A steady and growing supply of oxygen, supplied by cyanobacteria, was necessary to attain today's near-equilibrium conditions.
