A thermodynamic theory of evolution

As a closed thermodynamic system subject to an essentially constant free energy gradient, the biosphere must evolve toward a stationary state of maximum structuring and minimum dissipation with respect to this applied gradient. Since biological evolution occurs opportunistically through chance and selection, rather than as a direct response to the free energy gradient, the conformance of this phase of evolution with thermodynamics requires that natural selection, and the particular adaptive strategies employed by species of organisms, be related to the principles of increasing structuring and decreasing dissipation. In this paper, some general features of this relationship are proposed.
