On the thermodynamics of biological evolution
Journal of Theoretical Biology, 1978Abstract A theory is proposed which explains the peculiarities of biological evolution on the basis of classical thermodynamics. Notions are introduced of particular evolutions as components of the general evolution of the biosphere. Thermodynamic criteria of evolutions are formulated allowing experimental proof of the applicability of classical ...

Consciousness and Biological Evolution
Journal of Theoretical Biology, 1997It has been suggested that if the preservation and development of consciousness in the biological evolution is a result of natural selection, it is plausible that consciousness not only has been influenced by neural processes, but has had a survival value itself; and it could only have had this, if it had also been efficacious.

Economics and biological evolution
Environmental & Resource Economics, 1997The employment of insecticides raises the relative fitness of resistant insects; the use of antibiotics applies selection pressure in favour of resistant strains of bacteria; lower limits on fish net mesh size raises the advantages of smaller adults.

Acta Biotheoretica, 1968
Some theoretical examples of possibilities for natural selection in a prebiotic organic medium at the molecular level are given. These examples, presented in the form of simple kinetic models, are based on the idea that the occurrence of autocatalysis and self-duplication broke through the limitations imposed by contacts by chance with rare but ...

Copper and the biological evolution
Biosystems, 1983Copper is contained in a number of enzymes and proteins. A remarkable feature is that except for the electron-carrying blue copper proteins (azurin and plastocyanin) and copper-containing cytochrome c oxidase found in some cyanobacteria and some aerobic bacteria, all copper enzymes and proteins are found only in eukaryotes.

Abstract The chapter discusses the history of life on Earth, and the lessons to be learned from the neo-Darwinian synthesis of evolutionary biology. The long and complex sequence of events in the evolutionary history of life on Earth requires considered interpretation.

Human evolution is biological & technological evolution
Biosystems, 2020We are the human & machine species. The homo is just the inner part. The evolution of the human & machine species is oriented in time from the naked man to the man with progressively more powerful add-ons (artifacts, contrivances, devices, machines, science).

A mathematical model of biological evolution
Journal of Mathematical Biology, 1982In order to understand generally how the biological evolution rate depends on relevant parameters such as mutation rate, intensity of selection pressure and its persistence time, the following mathematical model is proposed: dNn(t)/dt = (mn(t) - mu)Nn(t) + muNn-1(t) (n = 0,1,2,3,...), where Nn(t) and mn(t) are respectively the number and Malthusian ...

The evolution of the chemical isotopes as an analog of biological evolution
Journal of Theoretical Biology, 1980Abstract A comparison is made between a biological adaptive landscape and the chemical isotopic landscape defined with three dimensions: the number of protons, the number of neutrons, and the stability of each isotopic nucleus. The courses of both biological and elemental evolution have been stochastic, leading from the simple to the complex; this is

Computational optimization and biological evolution
Biochemical Society Transactions, 2010Modelling and optimization principles become a key concept in many biological areas, especially in biochemistry. Definitions of objective function, fitness and co-evolution, although they differ between biology and mathematics, are similar in a general sense.
