(3) A process resulting in an increase in oxidation number.


Supplement

Re: Any other explanations other than Mutation?

... very small percentage of large animals get fossilized because to fossilize something it has to be separated from the atmosphere so as to eliminate oxidation and other weathering; landslides, ashes from volcanoes are good fossilizing events. An organism with an disadvantageous trait will die and ...
