When oxygen 1st developed on earth, it wiped out near 99% of all life….. Yup this is right (according to our present knowledge and proof). This is known as “The huge Oxygenation Event (GOE)”- this is as well recognized as Oxygen Catastrophe, Oxygen Crisis, Oxygen Holocaust, Oxygen Revolution, or huge Oxidation. According to Geological, isotopic, and chemical sign this major environmental modify occurred around 2.3 billion years ago.
Cyanobacteria, which appear on Earth some 200 million years previous to the The Great Oxygenation Event, initiated generate oxygen by photosynthesis. Before the GOE, any free oxygen they shaped was chemically seized by dissolved iron or organic substance. The GOE was the certain point when these oxygen basins turn out to be soaked and could not capture all of the oxygen that was shaped by cyanobacterial photosynthesis. After the The Great Oxygenation Event, the extra free oxygen started to gather in the atmosphere.
Free oxygen is toxic to obligate anaerobic creatures, and the growing concentration may have wiped out maximum of the Earth's anaerobic inhabitants at the time. Cyanobacteria were thus answerable for one of the majority important extinction events in Earth's history.
