Evolutionary Paper: The Process Of Aging

In particular telomere length has become a required biomarker for anyone analyzing the effect of and variables into human fitness. Telomere length has been related to obesity, bone demineralization and other aging indexes, including high risk of premature death and development of cancer. It has been found believable that the presences of short telomeres trigger cell senescence in vivo, in consequence affecting organ and tissue function. Their observation strongly support that telomere shorting is a major cause of cell senescence in organs with high proliferative potential, detectable in aged human individuals. Which causes the degeneration of organs and bones that lead to the age related diseases that are shorting the lifespan of humans. Telomere length has become an excellent predictive measure for some of these age related disease because of its close correlation to the

Aging, though it is usually defined as a biological process, it is also the gathered development of change with time. Aging is a continuous, complex and dynamic process that begins even before birth and ends with death. Unless death occurs at an early age, all humans grow old and experience the effects of the aging process. The process of aging does not

I do not believe that there is one explanation to describe the aging process. Physiological change is based on different factors like a person’s genetic. Some people are born into different gene pools that makes the aging process different for people. In review of my own family history, my maternal great grandmother lived to the age of 104. I view her aging process as successfully. She was active and mobile. Her health was fair. Physically she appeared to be in decent shape. She was able to recall events and information. Her skin was not youthful, but for her age it was not wrinkled. Her emotional and mental health appeared composed. It was said that her mother age in a similar way. This leads me to believe that hopefully I too may age gracefully due to my genetic

Aging is the amount of changes in person overtime. It is a multidimensional process, which can affect a person physically and psychologically. With age, people weaken and affect their memory. There are four types of aging: intrinsic, universal, progressive and deleterious. Intrinsic aging is chronologic aging, it deals with internal factors, and it decreased fat cells size, and damaged fat cells differentiation. Deleterious aging connects with aging will only be considered as part of the aging process if it “poor” for the individual. Universal aging deals with the process of how aging occur differently in all individual of species.

Aging and senescence, which is the decline in the physical functioning or performance of living organisms with age (Bergstrom, 2012), is also is studied using an evolutionary perspective. Research on aging has shown that it is a life trait that has been shaped over the years by natural selection (Neese, 2008). Aging is a process that occurs due to an accumulation of molecular damage that

Ageing involves the progression of age associated pathologies and diseases and decrease in healthy lifespan with respect to time. The increase in age related disease and decrease in longevity creates a functional foundation on which experimental research into ageing can be performed. Below are some recent studies that highlight current research and foundational studies that formed the basic knowledge on which most age related research has been done.

The article that I chose to examine was the Biological Anthropology of Aging. This article was written by Gillian H. Ice from the Department of Social Medicine. He studied in Ohio University College of Osteopathic Medicine. This article was published in 2005-2006 the publisher is Kluwer Academic Publishers-Plenum, Volume 20 Issue 2 from pages 87-90. It is written in The Journal of Cross-Cultural Gerontology. This journal is discussing the fact that aging in our population is increasing dramatically, and not only developed countries but also in developing nations as well.

In the new age, aging is an event that has confounded biologists for the past several decades. With new advances in medicine, people are living longer than ever before and as a result are experiencing a new phenomenon known as aging, where there is deterioration of physiological functions that are required for survival and fertility over time. Now that people can live past 50 years of age, they are likely to develop grey hair, muscle deterioration, memory loss and slowed sexual responsiveness. While most organisms go through the aging process, there is no single hypothesis that explains how or why aging and senescence, the physiological deterioration, happens. In most organisms, there is a trade-off between the energy allocated for early growth

Aging is the process of becoming older, as we age, multiple mutations occur that concern all the processes of aging well as it compromising a number of different genes. There are many theories of biological aging, such as the Cellular Aging Theory, Immunological Theory, and the Wear and Tear Theory. The Cellular Aging theory describes the process of aging in which cells slow their number of replication, thus giving each species a “biological clock that determines its maximum life span” and how quickly one 's health will deteriorate(Hooyman, 42). After a certain number of years, each cell which follows an apparent biological clock starts to replicate itself less, thus the specific individual or species slowly deteriorates. This theory gives

From the physical point of view, human aging is a process of cumulative changes, both morphological and physiological, resulting in a progressive diminution of our body and organs ability to defend from external aggression and to adapt to changing conditions.

When an individual is getting older it is important to educate them on how to grow old successfully and healthy. It is also important that health professional check for polypharmacy and conduct relevant assessments when necessary. With Reg, whose wife passed away unexpectedly 6 months ago, it is important he alters his lifestyle to lessen the impact of his loss. This can be done by following some social and psychological theories of aging. It is also important that the nurse who does community work for him to assess him daily to ensure he is getting the proper amount of care and to check if he needs additional care to be organised. This includes reviews of his medication to ensure he is not suffering from any side effects

April 6th 1944 in her home in Jacksonville, IL Mary Lee Elizabeth Smith was born. This is my grandma. At 71 years old she is the youngest of 8 children. She herself had 6 kids before having a tubal ligation at the age of 27, which resulted in two adhesions that had wrapped around her colon. Other surgical procedures include getting her tonsils out at sixteen years old, the removal of a benign “knot” from her neck, a cyst removal from under her arm and bunion removal. She currently lives with congestive heart failure, type 2 diabetes, hypertension, and arthritis.

Aging on the other hand is a process that affects the human and other organisms’ as a whole. It is, therefore, basically, the adding damages of tissues, cells, and molecules during the process of growth and development. It is a process that takes place in a lifetime span. The changes in the psychological process are permanent (Finch, 2007). The changes will, therefore, affect the way the organism balances the homeostasis process in the body. (Finch, 2007) The body then begin to become immune to the stress conditions in the long run. The declining capacity of the body to maintaining a balance in the homeostasis process is a risk condition to the health of the organism (Finch,2007). It is the reason the body becomes prone to diseases and complications. Some of the severe health issues that occur due to

Telomeres shorten after each cell division, until senescence marks the point, where they cease to divide. Once cells divide at a reduced rate and then no longer divide at all, the effects of ageing become visible. It should be noted that this is not the inevitable fate of every biological organism. As we reach the heights of sentience, our evolution would be reflected in our extended lifespan. From a scientific viewpoint, the human race has the capacity to expand their lifespan from 150 to 300 years in less than a century. Therefore, we have far from lived up to our full biological

There have been multiple disputes over whether our aging depends on the time our genes were programed to deteriorate, or whether aging solely depends on different factors that effect the way we will age over time. A very early theory of aging was from Leslie Orgel in 1963, he believed that errors in transcription from DNA lead to errors in proteins which build-up over time and cause more errors in transcription, creating an amplifying loop that eventually kills the cell and leads to aging (Orgel, 1973). The first idea is that our genes control how long we live, this means that we have genes that tell us how long we live. Many scientists believe that if you find the gene that determines our life span, we could possibly alter how long we live. The second idea is based on a theory that over time we damage our body and our DNA causing us to
