Mutations and errors in sexual reproduction allow for variation within a population.
These variations can eventually lead to the complex process of evolution in a species. The genetically derived mutation Polycythemia and the environmentally derived mutation lip augmentations, affect human evolution in a beneficial and detrimental way.
Evolution is change in the aspects of a certain species over a period of time. This is caused by mutations which are variations or differences in the genome. Both genetic and environmental mutations affect the evolution of life in a negative and positive way. Although genetic mutations are heritable some environmental mutations are inheritable because they are not encoded in the genome. Although theories of evolution …show more content…
One scenario where Polycythemia could be beneficial is in sherpas in the Himalayan Mountains. The increase in stamina from the excess amount of red blood cells would allow for better oxygen transportation. In the Himalayas, there is little oxygen due to high altitude. Having
Polycythemia would allow the sherpas the ability to hike and exercise more efficiently than someone who doesn 't have the mutation. This mutation could potentially affect human evolution by increasing our stamina yet making us more susceptible to heart attacks, strokes, and blood clots.The publics ' response to citizens with Polycythemia is minimal because polycythemia is is not a visible disorder. Since Polycythemia is a relatively uncommon disorder, most of the public is not educated enough to know about it. Having Polycythemia doesn’t affect an individual’s fitness in today 's society because there are measures being taken to prevent side affects such as heart attacks and strokes.
Procedures such as phlebotomy help people with Polycythemia by removing blood from the blood stream, decreasing the chance of stroke or heart attack. Medicines such as Hydroxyurea also help with the people affected with Polycythemia by reducing the number of cells in …show more content…
Without treatment some people affected by this disorder would die. Individuals who get treatment are able to reproduce because they have a higher chance of survival. This increases the gene frequency of Polycythemia within the population. This could affect the human population because more people have the gene. However, one could argue that treatment would not increase a person’s fitness because Polycythemia is diagnosed at an older age when people have already had children. In today 's society, people with disorders such as Polycythemia already have a family by the time they are diagnosed. Therefore, competition can 't select against or for it because they will not know if they have it until a later age. A variation that is externally derived is lip augmentations. Factors that cause this external mutation are due to humans being unsatisfied with the way they look. Humans also get lip augmentations to look better for a potential mate. This would increase their fitness by raising their chance to find a potential mate. Lip augmentations are performed by injecting a dermal filler into the lip. The most common dermal filler used today is a small gel called hyalurnic acid. Hyalurnic acid is
