Natural Process - Natural Selection

Abstract
Life is supported by a myriad of chemical reactions. To describe the overall
process we have formulated entropy for an open system undergoing chemical 
reactions. The entropy formula allows us to recognize various ways for the 
system to move towards more probable states.These correspond to the basic 
processes of life i.e. proliferation,differentiation, expansion, energy intake, 
adaptation and maturation. We propose that the RATE OF ENTROPY PRODUCTION by 
various mechanisms is the fitness criterion of natural selection. The quest for 
more probable states results inorganization of matter in functional hierarchies.

“Life is chemistry” is a cliché but it is one that deserves a reinspection.
For a long time, it has been understood that chemical reactions lead to 
chemical 
equilibrium. Gibbs was first to realize that this stationary state, where 
chemical potentials μ on both sides of a reaction formula are equal, 
corresponds 
to the maximum entropy [1]. Chemical reactions as well as other
processes, e.g. diffusion, heat flow from hot to cold and ion currents in 
electric fields that evolve towards increasing entropy are all called natural 
processes [2]. Does this mean that life is a natural process towards 
high-entropy states?

The question has remained open despite many studies [3–8].
Since high-entropy states are often associated with high
disorder and ordered structures are distinctive features of life,
it is customarily thought that living processes work to reduce
entropy rather than to increase it [9]. However, no firm proof
has been given and it has remained obscure what prevents us
from deriving characteristics of living matter from the fundamental
principles. Is it a missing concept or a misconception
or something else?
