Here: Aging Is Unavoidable For Humans
| COMPARING HAMLET AND THE GODFATHER | Aging is inevitable: this is gerontological dogma. And humans do inevitably grow old, which is probably why it seems so unlikely to us that other forms of life could escape aging. Escaping aging is not escaping death. Death is an inherent part of life, and it can strike any time. Jan 31, · Aging is an unavoidable outcome of life characterized by a progressive decline in tissue and organ function along with an increased mortality risk (Flatt, ). Aging is also the primary risk factor for major human pathologies, including cancer, diabetes, cardiovascular disorders, and neurodegen-erative diseases. Enquiry into the evolution of ageing aims to explain why a detrimental process such as aging would evolve, and why there is so much variability in the lifespans of living organisms. The classical theories of evolution (mutation accumulation, antagonistic pleiotropy, and disposable soma) suggest that environmental factors such as predation, accidents, disease, starvation, etc. ensure that most. |

Janet Simon Schreck Loyola Clinical Centers, Loyola University Maryland Baltimore Maryland Abstract The process of aging is unavoidable and unrelenting in human beings. Is aging a normal stage of human development or a disease that can be treated, delayed, or perhaps even cured? This article explores the aging process . |

Getting old is an inevitable part of life as no one can stop time. From getting wrinkles and bruising more easily, to growing small growths known as skin tags, there are unfortunately many signs of aging that show up as the years go on. It may seem impossible to hold onto your youth! The good news is that you can make some simple lifestyle changes that may help reverse the aging process, or at least slow it down so that you can keep it under control. Read on to learn 7 steps on how to reverse premature aging. The first way to help reverse the aging process is to always keep yourself hydrated. The average adult human needs to drink around 8 cups of water per day. Aging Is Unavoidable For Humans.
Enquiry into the evolution of ageing aims to explain why a detrimental process such as aging would evolve, and why there is so much variability in the lifespans of living organisms. The classical theories of evolution mutation accumulation, antagonistic pleiotropy, and disposable soma [1] [2] [3] suggest that environmental factors such as predation, accidents, disease, starvation, etc.

Natural selection will instead strongly favor genes which ensure early maturation and rapid reproduction, and the selection for genetic traits which promote molecular and cellular self-maintenance will decline with age for most organisms. August Weismann was responsible for interpreting and formalizing the mechanisms of Darwinian evolution in a modern theoretical framework.
Inhere theorized that ageing was part of life's program to make room for the next generation in order to sustain the turnover that is necessary for evolution. Natural selection is a process that allows organisms to better adapt to the environment, it is the survival of the fittest which are predicted to produce more offsprings. Natural selection acts on life history traits in order to optimize reproductive success and lifetime fitness.

Fitness in this context refers to how likely an organism is to survive and reproduce. It is based on the environment and is also relative to other individuals in the population.
Marathon of life history traits include; age and size at first reproduction, number of size and offsprings produced, and the period of reproductive lifespan. Organisms put energy into growth, reproduction, and maintenance by following a particular pattern which changes throughout their lifetime due to the trade-offs that exist between the different energy allocations. Investment in current vs future reproduction, for example, comes at the expense of the other. Natural selection, however is not so effective on organisms as they age. Mutation accumulation MA and antagonistic pleiotropy AP are two factors which contribute to senescence.

Note that somatic mutations are not heritable, they are only a source of developmental variation. Studies done on Drosophila melanogaster have shown that mutation accumulation drives the combination of alleles which have "age-specific additive effects" that cause a decline in stress response and ultimately an age-related decline in fitness. The first modern theory of mammal ageing was formulated by Peter Medawar in This theory formed in the previous decade with J. Haldane and his selection shadow concept. The development of human civilization has shifted Unavoidabe selective shadow as the conditions that humans now live in include improved quality of victuals, living conditions, and healthcare. This improved healthcare includes read article medicine such as antibiotics and new medical technology.]
