=== The Great Oxidation Event ===
Atmospheric and oceanic compositions have drastically changed since the formation of early Earth. One significant event, [[Great Oxidation Event|the Great Oxidation Event (GOE)]], marked the period of time in which oxygen became a major component of Earth’s atmosphere and surface ocean. However, the physical or biochemical drivers responsible for the transition from a reducing to oxidizing environment remains up for debate (Olejarz ''et al.'' 2021).<ref>Olejarz ''et al.'' (2021).

Commun.,'' ''12'': 3985. doi.org/10.1038/s41467-021-23286-7.</ref> To date, the evolution of [[cyanobacteria]] and cyanobacterial photosynthesis is commonly accepted as the primary driver of oxygen production, alongside several physical events behaving as proximal drivers of environmental state change (Kasting 2013; Inupakutika ''et al.'' 2016).<ref>Kasting (2013). What caused the rise of atmospheric O2?
