In any event, we can start our classification system at the "phylum" level.
If you do not understand the coeffcients of nuclear (solar and galactic)radiation as an energy inputand its qualitative energy budget or the biochemistry of say refrigerant bacteria such as phylum Pseudomonas the activators and inhibitors of chemical thermodynamics and thermodiffusion state it in your discourse,ie provide a risk matrix of the levels of understanding of unquantified variables and the correlation of accuracy (proof) of the gcm.
This, though, was a different line of evolution, even a different phylum, if "phylum" meant anything here.
