Evidence of Earlier Evolution for Cyanobacteria

Evidence of Earlier Evolution for Cyanobacteria
Sep-08-2015 0 comments Cube Biosystems

Shifting the paradigm of the Great Oxygen Event (GOE), researchers provide evidence that shallow archaen oceans contained dissolved oxygen as long as 3.2 billion years ago rather than 2.2 to 2.4 BYA, as widely held.  This implies that the oxygen producing cyanobacteria evolved earlier than previously thought.
