Atmospheric oxygen levels during stage 5 (0.54 Ga-present) probably rose to a maximum value of ca 0.3 atm during the Carboniferous before returning to its present value. The shallow oceans were oxygenated, while the oxygenation of the deep oceans fluctuated considerably, perhaps on rather ...
The evolution(演化) of the first animals may have oxygenated(供氧)Earth's oceans.New research led by the University of Exeter challenges the long held belief that oxygenation of the atmosphere and oceans was a precondition for the evolution of complex(复杂的) life forms. The study,published in...

The "Cambrian explosion" is one of the most fascinating episodes of diversification in the history of life; however, its relationship to the oxygenation of the oceans and atmosphere around the Ediacaran–Cambrian transition is not fully understood. Marine inventories of redox-sensitive trace elements ...

land plants and animals. Eukaryote fossils go back to late Paleoproterozoic time and perhaps earlier (Fig.1). Because of the importance of oxygen to animal metabolism, multicellular animals and oxygenation of the atmosphere and ocean co-evolved. Rising oxygen concentrations due to the GOE 2.4 billi...
