Abstract:

The rise of atmosphere oxygen that is chiefly resulted from the oxygenic photosynthesis illustrates a genetically consanguineous relation with the biological evolution. Microorganisms may also have played a major role in atmosphere evolution before the rise of oxygen, which shapes a microbial world before the Ediacaran. Even in today, these bacteria, as well as microscopic algae, supply oxygen to the atmosphere and churn out fixed nitrogen in Earth’s vast oceans. Earlier, less animal-influenced biospheres worked quite differently from the one currently occupied, with the Ediacaran-Cambrian radiation of organ-grade animals marking a fundamental shift in macroecological and macroevolutionary expression. Therefore, the rise of the atmosphere oxygen is actually a sophisticated geobiological process. Tracing the complex relationship between evolution and environmental change that is caused by the rise of the atmosphere oxygen will provide some important thinking approaches and researching clues for the further understanding of the sophisticatedly evolutionary history of the Earth.

Key words: rise of atmosphere oxygen, biological evolution and innovation, geobiology, research advancement
