There is also a need for a general theoretical framework that may allow researchers to handle an enormous amount of diverse observations related to aging phenomena. Empirical observations on aging have become so numerous and abundant that a special encyclopedia, The Macmillan Encyclopedia of Aging, is now required for even a partial coverage of the accumulated facts[ 1 ]. To transform these numerous and diverse observations into a comprehensive body of knowledge, a general theory of species aging and longevity is required. A general theory of aging may come in the future from a synthesis between systems theory reliability theory and specific biological knowledge. Reliability theory is a general theory about systems failure, which allows researchers to predict age-related failure kinetics for a system of given architecture reliability structure and given reliability of its components[ 2 , 3 ]. As for specific biological knowledge, many researchers believe that it could be provided by evolutionary theories of aging based on the Darwinian theory of biological evolution by natural selection[ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ].

British Dictionary definitions for evolution evolution noun biology a gradual change in the characteristics of a population of animals or plants over successive generations: Used in various senses in medicine, mathematics, and general use, including "growth to maturity and development of an individual living thing" s. Modern use in biology, of species, first attested by Scottish geologist Charles Lyell. Charles Darwin used the word only once, in the closing paragraph of "The Origin of Species" , and preferred descent with modification, in part because evolution already had been used in the 18c.

Biological Aging Theories Theories of biological aging need to explain how aging relates to the evolution process. More specifically, if the evolution process has caused organisms to evolve myriad other ways to survive longer and reproduce more, why does aging still exist? As summarized below, aging theories propose three different answers to this question and are based on three different versions of Darwin's survival of the fittest idea. Simple Deterioration Theories - Fundamental Limitations - "Wear and Tear" Many people believe that biological aging is simply the result of universal deteriorative processes such as oxidation, entropy, or wear and tear that cause aging in machinery, exterior paint, and other inanimate objects. These theories are superficially attractive if only human aging is considered but fail if life span characteristics of other species are also examined.

Paul Gosselin Among the many claims of the "scientific establishment" that of being neutral and objective is surely the most vaunted. The present essay will not seek to make a study of scientific objectivity in general, but rather to analyze the specific neutrality and objectivity manifest in the present day theoretical cornerstone of the scientific establishment: The following has been prepared on the basis of the conviction that scientists are, despite their use of logic and experimentation, still human beings like the rest of us and as such need an explanation of where they come from, a "myth of origin", to use the latest anthropological jargon. The following quote from B.
