Thus, changes in the composition of the earth's atmosphere, the emergence of aerobic metabolism, and finally the development of multicellularity were all brought about by cyanobacteria's release of oxygen.

Oxygen is a chemical element, a type of substance, due to its unique atom composition. The atomic number 8 of an oxygen atom, which is represented by the symbol O in its formal chemical formula, indicates that the oxygen atom contains eight protons in its nucleus.
