Evidence of Earlier Evolution for Cyanobacteria
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. |
