L.L. Ovsyannikov Species life span as a product of evolution


The article is devoted to the problem of species life span, as well as relatedthe problem of aging. The basis of the presented work is the concept of evolutionary optimality. As an optimized adaptive trait the species life span is considered, which, along with other adaptive traits, is a product of evolution. The author presents aging as an increase in energy consumption for self-preservation (metabolism, active metabolism, thermoregulation) with age. According to the proposed mathematical model, an age comes, the excess of which leads to a shortage of energy received by organisms with food. As a result, the body is forced to compensate the deficit of energy by the tissue of vital organs, which leads to death of the body. To determine the value of species life span, the author introduces the concept of aging coefficient, which establishes a relationship between energy expenses on self-preservation and age. Based on the evolutionary optimality of life expectancy, the magnitude of the aging coefficient is determined, which, as a result, makes it possible to express the species life expectancy as a function of other parameters organism and environmental factors. The author not only expounds the theory of the question, but also illustrates its validity with concrete calculate
