Evolution from a Thermodynamic Perspective
Survival of the fittest” is a tautology, because those that are “fit” are the ones that survive, but to survive, a species must be “fit”. Modern evolutionary theory avoids the problem by defining fitness as reproductive success, but the complexity of life that we see today could not have evolved based on selection that favors only reproductive ability. There is nothing inherent in reproductive success alone that could result in higher forms of life. Evolution from a Thermodynamic Perspective presents a non-circular definition of fitness and a thermodynamic definition of evolution. Fitness means maximization of power output, necessary to survive in a competitive world. Evolution is the “storage of entropy”. “Entropy storage” means that solar energy, instead of dissipating as heat in the Earth, is stored in the structure of living organisms and ecosystems. Part one explains this in terms comprehensible to a scientific audience beyond biophysicists and ecosystem modelers. Part two applies thermodynamic theory in non-esoteric language to sustainability of agriculture, and to conservation of endangered species. While natural systems are stabilized by feedback, agricultural systems remain in a mode of perpetual growth, pressured by balance of trade and by a swelling population. The constraints imposed by thermodynamic laws are being increasingly felt as economic expansion destabilizes resource systems on which expansion depends.

How did life on Earth arise? This question has captured the imagination of curious minds ever since the dawn of humanity. Countless myths have been told, but a plausible scientific explanation has resisted 160 years of vigorous research since Darwin. Now, for the first time in this book, physicist Karo Michaelian reviews a bold new theory founded on non-equilibrium thermodynamic principles. As with all irreversible processes, life could only arise, proliferate, and evolve by dissipating an external generalized chemical potential. Michaelian identifies this external potential as the ultraviolet (UV-C) photon potential arriving at Earth's surface during the Archean and the fundamental molecules of life as "self-organized" microscopic dissipative structures, i.e. pigments in the UV-C. The theory is drawing a lot of attention because of its ability to explain many of the salient characteristics of the fundamental molecules of life and because it provides a reason for the evolution of a complex biosphere. Large amounts of empirical data from epochs all the way back to the beginning of life and from some of Michaelian's own experiments all support the new theory. The implications are serious for many contemporary paradigms concerning life and evolution. Even the cherished Darwinian paradigm, with its implicit metaphysical "will to survive," selection only at the level of the organism, and the inescapable tautology in "survival of the survivors" (irrespective of Popper's recanting) must be reformulated on thermodynamic principles, and the way to accomplish this is presented in the book. Michaelian concludes that life similar, and not so similar, to our own should exist everywhere in the Universe wherever there exists the organic elements, UV-C light, and a dissipative solvent medium. In fact, he suggests that we have already discovered extraterrestrial life on other planets of our own solar system, and even within the galactic interstellar clouds of gas and dust, but have yet to recognize it as such under the old paradigms. A program for best searching for this extraterrestrial life at the different stages of its dissipation development is detailed within the book. Karo Michaelian has Ph.D. in physics from the University of Alberta, Canada and has worked at various research institutes throughout the world in topics ranging from nuclear physics and nanoparticles to complex systems and non-equilibrium thermodynamics. His book makes fascinating reading in understandable language for the serious amateur but also contains much detail, including mathematical derivation of thermodynamic principles, for the professional who wants an in-depth understanding. The book contains 422 pages with 140 images and diagrams and 414 references. A detailed historical sketch of origin and evolution of life research is presented and critically analyzed, including; Ideas from Antiquity, Darwinian Theory, the Miller Experiments, the RNA World, Panspermia, and Gaia Theory. The thermodynamic foundations of the new theory are developed in the first 6 chapters and the corroborating evidence presented in the next 12. Another 2 chapters discuss contemporary paradigms in need of reform, and the last discusses dissipative life in other parts of the Universe. Mathematical demonstrations are left to boxes that can be skipped without much loss of continuity of argument. Analogies help to make the theory understandable to those who may not have formal training in mathematics or who lack an understanding of non-equilibrium thermodynamics.
Evolutionary Essays
Evolution is nature's most fascinating process, the possibility given sufficient time to combine simple inorganic compounds to more and more complex biochemical compounds, which make up more and more complex organisms. It is therefore crucial in our effort to understand the evolution to see it from as many different angles as possible. This books draw an image of evolution from the thermodynamic viewpoint, which gives new and surprising insights into the processes and mechanisms that have driven evolution. This new thermodynamic interpretation has made it possible to quantify the various steps of evolution and to show that evolution has followed an exponential growth curve. - The first comprehensive thermodynamic interpretation and explanation of evolution - This thermodynamic interpretation makes it possible to quantify the various steps of evolution - This interpretation explains the wide spectrum of different mechanisms on which the evolution has been based
