The evolutionary Theory of Aging - Essay ExampleThe following discussions will try to lucubrate the distinguishable theories that have been suggested to explain how these changes take place. The following discussions would be a on the different theories as they try to explain how the genes responsible aging evolved over clock. Evolutionary possibility of aging is one of the widely used theories to explain aging of individual animals. According Weismann (1999), evolutionary theory of aging is relevant as it gives go account of evolution of individuals with respect to the aging of the cells that are possessed by those particular individuals. He as well argues that the most important aspect of evolutionary theory is that it gives an account of the possible evolutions of the cells that may result into the death of the cells or reduced performance and hence increases their susceptibility to death. Several researches that have been done by different researchers hence however reveled th at it is difficult for this theory to contradict the Darwins theory of evolution. ... In this context, the genetic materials that are supposed to play vital part during this time are lost and hence the negative impact begins. For example, the replacement of the tissues and other body parts may be done but the coding remains may not take place accordingly and hence this result to the production of cells and the appearance of old tissues. The other important aspect of this model is also the appearance of the late acting genes that are harmful to the genetic system. It is important to note that it is these late harmful genes that contribute to the aging butt againstes. It is believed that these genes interfere with the processes of normal surgery of individuals and hence it is difficult for the normal genes to act accordingly. Whether the lack of the late acting genes or the dangerous late acting genes, the main idea of this model is that the presentation of the aging process takes place as a result of complication in the late acting genes within individuals. While it is a strong guide on to explain the aging process in theory, the question that remains unexplained is that the initial process that initiates aging is not well explained. In this context, it is clear that the process does start as a result of genetic complication. However, the theory remains dormant on the sources as this is not explained why these genes do not conk on the young people or those who have only lived for few years. However, this model has strength in explaining the genetic problem which is more explanatory to the unimaginative aspect of aging. The other model is that which was suggested by William assert that the aging that occurs to individuals takes place as a result of pleiotropic effect from the genes. It is believed that these genes are beneficial in the beforehand(predicate) years but
