Comparative nutrition, growth and longevity.
are already aware of all these many difficulties and are ready to accept the convenience of the concept of ‘fitness’ in evolutionary theory, when faced with the necessity to explain. Finally, I think that it is only right to point out that man refuses to conform to many of the generalizations which have arisen in comparative study. All would agree that Adrian Spigelius of Padua in the 16th cent...
متن کاملNutritional intake and longevity. International comparative study.
We tried to make the relation between the state of nutritional intake and the life span of human beings clear by comparing them internationally. 1. Observing the correlation of nutrition and life span of both advanced and the other nations, the tendency is almost the same with that of the middle and low developed nations. It can be concluded that in any case the more the nutritional intake is, ...
متن کاملComparative Endocrinology of Aging and Longevity Regulation
Hormones regulate growth, development, metabolism, and other complex processes in multicellular animals. For many years it has been suggested that hormones may also influence the rate of the aging process. Aging is a multifactorial process that causes biological systems to break down and cease to function in adult organisms as time passes, eventually leading to death. The exact underlying cause...
متن کاملMitochondrial DNA Damage and Animal Longevity: Insights from Comparative Studies
Chemical reactions in living cells are under strict enzyme control and conform to a tightly regulated metabolic program. However, uncontrolled and potentially deleterious endogenous reactions occur, even under physiological conditions. Aging, in this chemical context, could be viewed as an entropic process, the result of chemical side reactions that chronically and cumulatively degrade the func...
متن کاملWide‐scale comparative analysis of longevity genes and interventions
Hundreds of genes, when manipulated, affect the lifespan of model organisms (yeast, worm, fruit fly, and mouse) and thus can be defined as longevity-associated genes (LAGs). A major challenge is to determine whether these LAGs are model-specific or may play a universal role as longevity regulators across diverse taxa. A wide-scale comparative analysis of the 1805 known LAGs across 205 species r...
