The equilibrium theory of life evolution

Apparent biodiversity on earth exists only if we compare different species separated from their environments. Meanwhile coexisting species have to be identical in terms of energetic interactions. Consider the biosphere as a network of chemical reactions. This leads to the conclusion that forces which drive life evolution may be found inside the process of the transformations of molecules. From the thermodynamic point of view the system of reacting particles reaches a steady state when the chemical potentials of reagents become equal. Interactions between chemical compounds taking part in concurrent reactions and the equilibration of their chemical potentials is the essence of biological evolution and its only driving force.

The Waterwheel in the Waterfall

A fundamental problem in evolutionary ecology research is to explain how different species coexist in natural ecosystems. This question is directly related with species trophic competition. However, competition theory, based on the classical logistic Lotka-Volterra equations, leads to erroneous conclusions about species coexistence. The reason for this is incorrectly interpreted interspecific interactions, expressed in the form of the competition coefficients. Here I use the logistic Lotka-Volterra type competition equations derived from the so called resource competition models to obtain the necessary conditions for species coexistence. These models show that only species with identical competitive abilities may coexist. Due to such relations between competing species ecosystems biodiversity decreases in the course of evolution.
