Before searching for examples for each of the terms, it is necessary to define the scope of it: what is natural? Or specifically to this assignment, what is PURE natural and non-human? Is it possible to find a piece of nature and declare that no human being has ever done any impact on it? Given the fact that humans themselves as objects being inseparable parts of nature. The answer is no. So the search is not set to outrun the expansion of the humane realm, but to go beyond it. That is, the meta-nature as a higher level nature to which we all subject to.
example: DNA
The DNA in all cells of a living creature is identical. This is a decentralized strategy for the storage of biological information and the basic fact that allows cloning technology to exist.

example: Chemosynthesis bacteria
These bacteria use the oxidation of inorganic compounds to extract energy and sustain it. This is an alternative approach to biological energy adaptation other than photosynthesis.
