How Human Disease Has Impacted Our Evolution - 1332 Words

How Human Disease Has Impacted Our Evolution Human Disease is an issue that is still constantly trying to be solved and cured in our society. Health care is a critical issue in politics because so many people are still seeking and needing treatment for a variety of illnesses. This is kind of surprising to consider since it is the best time in human history to be alive in terms of healthcare. In the past, humans easily died of many diseases that have been completely cured and unheard of today, such as polio. The Black Plague that happened hundreds of years ago is still widely discussed, and could be argued to still be affecting civilization today, as the event caused severe damage on a vast portion of the population. Events such as these†¦show more content†¦Interestingly, the adaptation of humans to disease may date all the way back to the bottleneck that would eventually change our ancestors into behaviorally modern humans. A theory has been proposed that the activation of two genes that affect the human immune system created the modern human around 100,000 years ago. According to the study’s theory, humans have been adapting to disease for thousands of years. Clearly, disease and the adaptations of humans are correlated to their environment (LaFee, S., 2012). Historical events, such as the agricultural revolution and the bottleneck of genes, has forever altered humans’ resistance and as time continued, the significance of medicine only intensifies. The emphasis on medicine and disease prevention caused the second epidemiological transition. The first epidemiological transition occurred during the agricultural revolution and contrary to before, the second transition only occurred in certain global populations. Many infectious diseases were eliminated; however, many chronic diseases became the main area of focus. Chronic diseases led to humans shifting their priorities in terms of lifestyle and adaptations, especially in first world countries. Foods high in fat and sugars became the norm. This caused people with certain genetic codes and personality traits to gain weight at an alarming rate, leading to an obesity epidemic.

Whether these improvements increase physical attractiveness through cosmetic and plastic surgeries, or decrease likelihood of hereditary diseases and disorders in embryos, they have recently become a very controversial topic in all societies around the world.

Moalem writes, â€Å"Why would you take a pill that was guaranteed to kill you in forty years? Because it will save you tomorrow. Why would we select for a gene that will kill us through iron loading by the time we reach what is now Middle Ages? Because it will protect us from a disease that is killing everyone long before that.†Read MoreThe Definition of DNA916 Words   |  4 PagesDNA: DNA is a double-stranded nucleic acid that contains the genetic information for cell growth, division, and function. DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus but a small amount of DNA can also be found in the mitochondria .The information in DNA is stored as a code made up of four nitrogen bases which are adenine (A), guanine (G), cytosine (C), and thymine (T). these nitrogen bases are bind withRead MoreThe Definition of DNA904 Words   |  4 PagesDNA: DNA is a double-stranded nucleic acid that contains the genetic information for cell growth, division, and function.

Imagine a world where most diseases and cancers have either been cured or have treatments to help people with them. Where there is no longer a regular doctors check up and now they would now take a look at what’s inside you. Where doctors will now look at the genes in your genome and find the problem in there. After they find the spot where there is something wrong, they would easily know what it is and give you a diagnosis and a treatment. Due to the Human Genome ProjectRead MoreCharles Darwin : Father Of Evolution1582 Words   |  7 PagesCharles Darwin:Father of Evolution Charles Robert Darwin was born February 12, 1809.

Theoretically, is it really true that an apple so little, contains ingredients that can prevent one from seeing a physician? If this apple is genetically modified with ingredients that can help fight diseases and virus, then assumably there would be no need to see the doctor. The issue of genetically engineered apples may lead to a new set of issues in the supermarket. Andrew Pollack wrote the article, That Fresh Look, Genetically Buffed, in the New
