Have you notice that some people are just not born with a good physical appearance or good health? This is because some people are not born with the immaculate genes that those fortunate people are born with. The great Aristotle once said, Those who are sprung from better ancestors are likely to be better men, for nobility is excellence of family. (Dobzhansky 8) Genetics determine many birth defects, disease, and cancer as well Our surrounding environment, which could include pollutants contribute to mutating genes which could also lead to disease or other health problems. Genetics isnt simply the study of the inheritance of traits but also with how humans live, grow, and develop. (Bornstein 12) Although genes predetermine and limit someones health, exercise can enhance a persons health and physical appearance.
Our genes influence a persons physical appearance and as well as health. Our growth, development, health, and appearance is effected by our hereditary genes. Hereditary genes are genes which are inherited by ones children. Certain physical characteristics undoubtedly run in the family. Even a newborn baby is declared by admiring relatives to have Dads eyes and Moms mouth or other particular features that are somehow different from the average yet specific to the parents.
All of these and many other characteristics are the results of heredity and of genetic programming involving both parents. (Marshall 7) Everyone shares genes with their relatives, and have half of each of our parents genes. Our genes make us all unique, making no one the same. No one has exactly the same genes, even twin have microscopic differences. Some people are born with the genes which inevitably make them obese.
No matter how healthy they eat or how much they contribute to exercising, good health is virtually impossible. (Marshall 33) Although some people are stricken to bad health, our environment shapes who you finally become from the moment of conception onward. Just as a twig is bent, environment can change the first impression or appearance of something or someone all the same. For example, someones skin color can be strongly changed by outdoor life or can be lightened with no exposure to outdoors. You can not change your genes but you can modify it with your surrounding environment, like exercising. With a balanced diet and proper exercise, that obese person can make some positive change in their physical appearance and as well as the level of health. (Killing 191) But our environment does not always contribute to our health but sometimes deprives it. Environment pollutants contribute to mutating genes, which could cause or lead to disease or other health problems.
Evidence shows that heredity is, rather, a conditioning with which a new individual enters the world. What heredity does is set a stage for the interaction of the developing human with its environment. (Dobzhansky 14) You can say it is an advantage to have good genes but it is up to you to use them. Your genes can only take you so far, health is up to you. Environmentally-influenced characteristics cannot be inherited.
If the child of parent weight lifters could inherit an environmentally-shaped characteristic, they would all have larger muscles. But there is a difference. A child may, however, inherit the potential to develop larger muscles, and the environment effect of intensive training could fully develop the inheriting tendency. (Marshall 33) As I was saying earlier, your genes limit your physical capabilities, which can sometimes not be overcome no matter how much exercise is done. For example, some babies who often have abnormalities or deformities are at birth and result in a child with down syndrome.
These unfortunate ones are usually short in stature, have an extra fold of tissue on their eyelid next to their nose, and are mentally retarded. This shows that exercise does not always guarantee a healthy life. What someone accomplishes in their life is essentially settled and predetermined by their hereditary. From a herditarian point of view, man is a creature born with his character and abilities fixed and unchangeable. (Dobzhansky 8) DNA (deoxyribonucleic acid) sequence differences between people can reveal who is healthy and who is stricken by or susceptible to diseases like cancer. The information within our cells that causes us to develop in a particular way is stored in genes. It is also known that evolution is the process by which individual, with genes that give them an advantage in a particular environment, produce offspring that are more successful then their competitors.
This is also known as Darwin's own, survival of the fittest (Marshall 79) With genes determining a persons health and physical appearance, undoubtedly, exercise is beneficial no matter what the circumstances. Daily exercise can lower risk of obtaining diseases or other harmful health problems. It is shown that those who refuse or do not exercise are prone to a more unhealthy lifestyle compared to those who take the time to exercise daily. It is also shown that daily exercise contributes to a better life and a prolonged life as well.
The most superficial benefit of exercising is your advantage to a more attractive physique. It is true that some have a tendency to have a better physique, even before beginning to understand the meaning of exercise, but this is due to the fact that that person has the proper genes which enables him to have an easier time to in being physically fit. Although some are naturally fit, others can become fit as well with the help of a good workout routine and a proper diet to go along with it. As I have said time and time again, exercise itself cannot guarantee a healthy life because of the many other factors which can cause unavoidable health problems. It is genes which is the basis of how healthy a person is or becomes.
But environmentally-influences genes can aid a persons problem if he does have one with his health and his physical characteristics as well. Just as exercise has helped millions to become healthier and more satisfied with their health as individuals.
