The Thermodynamic Evolution of Heterogeneity



A commentary on Jeremy England's new thermodynamic account of the origin of life—which is no doubt basically correct. It provides a general principle driving the natural selection of complex structures, and a more general framework connecting Darwinism and physics:

The notion that evolution, from simple material forms to complex organic beings, societies, and cultural phenomena, is the consequence of basic thermodynamic principles and obeys simple laws involving the circulation of energy was formulated by Spencer already in the nineteenth century. Dissipation of energy plays an important part in his definition of evolution, which runs thus: "Evolution is an integration of matter and concomitant dissipation of motion; during which the matter passes from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity; and during which the retained motion undergoes a parallel transformation" (First Principles, XVII). Of life he gave a minimalist, structural and ecological definition which favours an evolutionary continuity with non-life, as follows: "life is definable as the continuous adjustment of internal relations to external relations" (IV).
