Survival Of The Sickest Essay

Improved Essays
Dr. Sharon Moalem and Jonathan Prince both collaborated on the New York Times bestseller, Survival of the Sickest, which discusses how organisms surpassed their challenges through methods of evolution or medicine. The human race evolved and used medicine to combat the environment and the invaders trying to enter their body. One form of invader was Malaria, a disease spread from host to host by female mosquitos. Some invaders are already embedded in our DNA like the disease hemochromatosis. This disease is inherited from ancestors and isn’t contagious unlike other invaders. Another disease, Diabetes, is where the body produces no insulin. This disease can be triggered because it is either inherited, caused by the environment, diet, or infections. …show more content…
Some researchers believe that Diabetes is an autoimmune disease that attacks the precise cells in the pancreas that are responsible for the production of insulin. But, diabetes doesn’t attack or target any specific organ. Diabetes is just the relationship between the body and glucose. Glucose is the body’s fuel essential for the body’s survival. Insulin stores glucose into the liver, fat cells, and muscles so it can be used when necessary. Diabetes is a disease where the body produces little to no insulin causing dangerously high sugar levels. These high sugar levels can cause dehydration, coma, and death. Diabetes was originally discovered thousands of years ago. It’s very widespread around the world and has a very particular geographical region of origin for type 1 diabetes. Type 1 diabetes tends to occur more in Northern Europe. Type 2 diabetes tends to occur more in obese people; people who don’t eat right. Diabetes can be treated with insulin shots, disciplined diets and exercise, and extreme attention to blood sugar levels. This disease impacted humanity because it opened the eyes of many people about how their diet affected their health. It revealed that obese kids had a greater chance of getting Type 2 diabetes which shows the connection between diabetes and diet. This disease conferred an evolutionary advantage during the ice age when …show more content…
Hemochromatosis is a hereditary disease that is bred into our genetic code. Hemochromatosis is a disease that targets the iron defense mechanism in the human body. This defense system limits the amount of iron in places susceptible to allowing infectious agents into our body. These agents need iron to thrive and by limiting their iron source, they are fighting the infection. Humans with Hemochromatosis have this defense system on at all times suppling the body’s blood with excess iron. In addition, humans with Hemochromatosis continue absorbing iron and their bodies don’t get rid of the excess iron. Symptoms of Hemochromatosis are tiredness and aching pains in the body. This disease will lead to liver failure, heart failure, diabetes, arthritis, infertility, psychiatric disorders, cancer, and ultimately death. Hemochromatosis is thought to be originated in Northern Europe during the time of the Vikings. The Vikings were thought to have a belligerent and bloodthirsty culture so they lost blood frequently. As a result, their body evolved to produce more iron to account for that major blood loss occurring in their battles. Hemochromatosis is treated through the process of bloodletting or drawing blood from the patient. Bloodletting

    The physiology of a hemochromatosis person always thinks that their body contains low amounts of iron, therefore, continue to absorb iron from the body. Excessive amount of iron is bad because it can damage joints and other physiological functions. Drastic conditions that hemochromatosis causes are liver failure, heart failure, arthritis, cancer, and even death. As suggested in “Ironing it Out,” the Black Plague contributed to the development of hemochromatosis because with increase amount of iron causes an individual to be prone to infections.

    In order for the body to function effectively, the body muscles and tissue need oxygen. If there is too little iron in the blood, it can causes a decrease in the amount of red cells in the blood that delivers oxygen to the body. Anemia is a common diagnostic term describing a decrease in number in function of erythrocytes or red blood cells (RBCs), and is the most widespread hematological disorder. In order to determine types of anemia, the anemia has to be classified by preforming a complete blood count along with other test. These test help provide a diagnosis that directs treatment and prognosis (Gulanick & Myers, 2014).…

    How Diseases Saved Humanity Survival of the Sickest, a book written by Sharon Moalem, discusses various diseases that have stayed in our gene pool due to the positive influence they had on humanity’s evolution. Despite having bad reputations, these diseases have given different populations a survival and evolutionary advantage over other groups hundreds and even thousands of years ago. Those populations, well in health and being, continued to reproduce and passed on the disease to their offspring, and with the evolutionary advantage provided, they also continued to survive and reproduce. Nowadays, these diseases can become a burden to everyday life, hindering someone to complete daily tasks with a lack of effort, due to modern technology…

    There are many diseases in the world that are deadly but acted as an evolutionary advantage in the past to help us, humans survive, reproduce and evolve into the species that we are now. For example, in Survival of the Sickest by Doctor Sharon Moalem and Jonathan Prince, it discusses diseases such as hemochromatosis, diabetes, and favism or glucose 6 phosphate dehydrogenase (G6PD) deficiency which all are deadly but helped humans survive in the past. Hemochromatosis is an inherent disease that disrupts the metabolism of iron in the body. Instead of letting excess iron pass through your body, the disease makes the body think that it never has enough iron and the body will keep absorbing iron for indefinite amounts causing high…

    In most people only 10 to 15% of iron is absorbed from their diets. Hepcidin is the hormone that regulates blood iron concentration. It is secreted by the liver and limits how much iron the small intestine absorbs and how much is released from the body. When there are low iron levels, hepcidin release is put on hold to increase the amount of iron being absorbed and raise blood iron concentration. When there is an excess amount of iron in the diet, hepcidin is secreted to decrease the amount of iron stored in the body (Sizer & Whitney,…

    Sickle Cell Disease Throughout the world, approximately 300 million individuals are heterozygous for a mutation in the β-globin gene, meaning they carry the sickle cell trait (Key, Connes, & Derebail, 2015). Of those 300 million individuals, 100,000 Americans are affected by sickle cell disease, making it the most common inherited blood disorder. Every single cell in our body needs oxygen to function efficiently, and the role of hemoglobin in red blood cells is to transport oxygen from the lungs to the rest of the body (“Sickle Cell Disease”, 2016). In a normal individual, the red blood cells have a disc-like shape that grant it flexibility and allow it to move through the smallest of vessels.…
