History and Evolution of Cyanobacteria

“Genomics and evolutionary studies have provided insights into the evolution of core proteins involved in oxygenic photosynthesis and the appearance of the Cyanobacteria’s common ancestor. Amongst prokaryotes, Cyanobacteria have left some of the best fossil records enabling molecular clock studies. Age estimates of the gene family of PSI and PSII are consistent with the geological record showing traces of oxygen throughout the Archean eon (4–2.5 Ba); these findings implied that oxygenic photosynthesis was already established by 3.0 Ba.” - Patricia Sánchez‐Baracaldo and Tanai Cardona (2019) On the origin of oxygenic photosynthesis and Cyanobacteria.
