History and Biological Evolution
Philosophy of Science, 1941What is the relationship of history to the phylogenetic evolution of man? Historians, like all specialists, are wont to restrict themselves to their own problems and, therefore, do not deal with this question. Only some popular books on the history of the world cross the dividing line between social and natural science.

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 ...

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 ...

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.

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.

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.

The essence of biological evolution
Uspekhi Fizicheskih Nauk, 1983The current state of the theory of biological evolution is reviewed. Evolution is compared with the cosmological processes of structure formation. Both occur in dissipative systems and are governed by export of entropy. The objections to Darwin's theory are discussed and rejected.

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).

2020
Biological evolution, the theory of natural selection and of common descent, is a triumph both of human reasoning and scientific undertaking. The biological discipline of evolution contains both a chronicle of human endeavour and the story of life on Earth.

The evolution of biological macromolecules
Contemporary Physics, 1984Abstract The red colour of blood has excited the emotions and interest of man since the earliest records of history, yet never has the most imaginative of the literati conjured up a proposal that this incarnadine hue could reveal a story of the evolution of all animals, going back hundreds of millions of years to a common ancestor (Thomas H.
