ScienceDaily (Oct. 9, 2010) — An international team of scientists, exploiting pioneering techniques at Arizona State University, has taken a significant step toward unlocking the secrets of oxygenation of the Earth's oceans and atmosphere.

the appearance of large predatory fish as well as vascular plants approximately 400 million years ago coincided with an increase in oxygen...

 

The bodies of such plants decompose with difficulty, making it easier for organic carbon to be buried in sediments...

 

The consequence is a rise in the amount of oxygen in the environment...

 

Then, the rise in oxygen made it possible for larger animals to evolve.

Oxygen is the most abundant element on earth making up 46% of the mass. The importance of oxygen is in its ability to accommodate more electrons than it has protons. For example, in oxide or O-2, there are ten electrons and eight protons. This happens because of the integration of the EM force. The magnetic addition of the electron orbitals is stronger than the electro-static repulsion. The net effect is the sum of the EM force favors extra electrons.

 

If we start with a hot earth, 46% mass of oxygen, this means a dominant scavenger of electrons covers the earth, to form oxides of all types, such as water. If we assume an iron core, this means an even higher oxygen elsewhere.This would suggest that even nitrogen gas would become NOx or nitrogen oxides. Was life also responsible for the nitrogen gas within the atmosphere?

 

To form N2 from NOx we need a way to reverse the primal oxidation. Bacteria can do this. But this would mean a competition with plants, who need the nitrates as part of their food supply. I often wonder whether competition, led to the present atmospheric N2/O2 concentration.
