In this paper, we discuss the evolution of skin pigmentation. In order to understand the evolution of skin pigmentation, we need to start off at the beginning and learn about melanin the main factor in skin pigmentation. The difference of your production of melanin can be a big factor in the medical issues you can get from ultraviolet radiation. Your skin is a layer of protection and similarly, your skin color is a layer of protection from the sun’s UVR. Based on where you live there are different strengths of UVR that can impact what skin pigmentation you will have illustrating the distribution of skin color with lighter skin in higher latitudes. Skin colors evolutionary cause is both because of natural selection and sexual selection.
Over time, people have evolved and changed developing different skin pigmentation. They have developed different skin colors with different undertones. The pigmentation of the skin occurs due to melanin, which is controlled by at least 6 or more genes in the human body, TYR, TYRP1, TYRP2, OCA2, SLC45A5, MC1R, and more (Yang, Zhaohui; Zhong, Hua; Chen, Jing; et al. 2016). With the constant variety of skin color

Despite having darker skin pigmentation, they live in the northern latitude and have not yet been naturally selected out. Due to their location, there is less UVR that should cause them to gain the Medical problems we discussed in the Medical Issues section about, but these specific groups of people are not vitamin D deficient due to the foods they eat. Their consumption of fish and sea mammal blubber allows them to regain all the vitamin D that the sun cannot penetrate their darker pigmented skin to form. Since they have only lived for 5,000 years there has not been enough time to significantly lower their melanin production to be naturally selected. Down below is a graph showing the distribution based on
Anthropologists and geographers have studied and overtime come to the conclusion that distribution of skin color is not random. Darker skin color has been found to typically come from near the equator and lighter skin colors are typically coming from closer to the north and south poles. Over the years, researchers have found that darker skin colors has protected the skin from having skin cancer. Recent studies have shown that “skin color is the product of natural selection acting to regulate the effects of the sun’s ultraviolet radiation on key nutrients crucial to the reproductive success” (169).
The first chapter focuses on the first impressions between the people of different color also the reasons Africans had evolved or changed into what they now appeared to be. The section on causes of complexion was both fascinating and entertaining. Many of the theories were of the wall and far fetched. One such opinion of how Africans gained their complexion that the book gave includes an ancient Greek myth of Phaeton. This character drove a chariot into the heavens and thus altered in his appearance (p11). Though this Greek myth, probably not the truth of how Africans gained their color many did believe it probably had something to do with the sun. The theory of equatorial dwellers of Africa, this being the reason for the skin pigmentation, became illogical once Africans were compared to the Indians living in the hottest parts of the New World (p14). Some believed that the African was merely dark because they had left their colder northern climate. Experiments quickly ruled this out as a possible answer (p15). The most far-fetched and humorous theory came through the biblical illustration involving Noah. Many believed it the curse given upon Noah’s son Ham for “looking upon his father’s nakedness” (p17). Each of these contrasting views on color needed to be used in this book. For no better reason in that it showed from an initial point that the English viewed the color of the Africans as a plague. Instead of excepting that Africans may in fact be different, the English consistently made attempts to explain the dif...
Based from the film “melanin plays a role on how Africans have been able to create and developed some of the sciences that they have come to be known for”. It is also believe that melanin is a factor to soul because people with more of it moves, speaks, and acts differently than those who do not. According to a group of Africans known as the “melanin scholars” they reported a scientific base that “melanin is involved in the regulation of all psychological and physiological processes of the human body.” This makes people with more melanin stronger and smarter than those with less.² This is why, according to Welsing, whites had ambition to destroy the African race because they were inferior to their genetic superiority. In agreement to Welsing, Wade Nobles, Richard King, and other researchers/ scientists reported that whites are not entirely human since they stopped evolving with the central nervous system
Back in the early 1800’s, the color of one’s skin mattered amongst African Americans and Caucasian people. There was infidelity between the Caucasian slave owners and the African American slaves. Of course, the outcome of that produced a fairer toned child. In most cases the child could pass as white. The mixed toned kids got to be inside doing housework, while the dark Negroes worked in the fields, under extraneous work conditions,”their dark-toned peers toiled in the fields”(Maxwell). From the early 1800’s to modern day, there is controversy that light or bi-racial African Americans are better than dark colored African Americans. African Americans had to go through tests to see if they were able to receive priviledges that white people received,”light-skinned African Amerians receive special priviledges based off of their skin shade”(Maxwell). If an African American did not receive the priviledges similar to white people then they would try to change themselves to fit in,”African Americans are using bleaching creams so that they can make their skin lighter , just to achieve the standard beauty”(Brooke). As much as one will not one to discuss this topic, statistics shows how people are more lenient towards light and fair skin tones.Light oor fair coloredAmericans that poseess Caucasian features are prefiebly preffered.
Tanning is a commonly used by Caucasian women to cause their skin tone to darken. Melanin is what gives skin its color. Naturally, when we are exposed to sun, the production of a pigment known as melanin starts which itself acts as a deterrent to the burning effects of ultra violet rays of sun (Pakhare). Some Caucasians find it necessary to tan to increase beauty. It is not necessary to tan to increase beauty.
In today’s society, it is acknowledgeable to assert that the concepts of race and ethnicity have changed enormously across different countries, cultures, eras, and customs. Even more, they have become less connected and tied with ancestral and familial ties but rather more concerned with superficial physical characteristics. Moreover, a great deal can be discussed the relationship between ethnicity and race. Both race and ethnicity are useful and counterproductive in their ways. To begin, the concept of race is, and its ideas are vital to society because it allows those contemporary nationalist movements which include, racist actions; to become more familiar to members of society. Secondly, it has helped to shape and redefine the meaning of
Our daily lives are affected by race whether we are aware of it or not. How we live different aspects of our lives depend on the colour of our skin. From the types of jobs we have, the income we earn, where we live etc. In societies fundamentally structured by race, it is important that we do not abandon the notion of race, but instead pioneer a revolution in the way that races are understood. In this paper, I will examine how the dominant groups in society define race in terms of biology, which leads to the notion of white privilege, which is their advantaged position in society, at the expense of other racial groups.
Albinism happens when one of numerous genes is fault. Each of these genes offers orders for making one of several proteins involved in the making of melanin. This imperfection may outcome in the nonappearance of melanin production or a cheap quantity. Melanin is produced by cells called melanocytes, which are found in your skin and eyes. The amount of coloring varies. Some people gain a little pigmentation in their hair or eyes when aging. Some develop pigmented spots on their skin. A person with total absence of melanin is called an albino. One with only a small amount of melanin is described as albinoid. (What is Albinism by Right Diagnosis April 22, 2014).
Race, as a general understanding is classifying someone based on how they look rather than who they are. It is based on a number of things but more than anything else it’s based on skin's melanin content. A “race” is a social construction which alters over the course of time due to historical and social pressures. Racial formation is defined as how race shapes and is shaped by social structure, and how racial categories are represented and given meaning in media, language and everyday life. Racial formation is something that we see changing overtime because it is rooted in our history. Racial formation also comes with other factors below it like racial projects. Racial projects seek
Oscar Wilde once wrote: “It is only shallow people who judge by appearance. The true mystery of the world is the visible, not the invisible” (qtd in Davis 1). Obviously, humans have all been created differently. That is why we all do not look alike. But now, the idea of having the ideal shape and look is one of the issues everyone has to deal with. Some want to get thinner, while a few do not care about it. Others even change the color of their skin. The desire to be like someone else is getting bigger and bigger for so many reasons that cannot be completely explained. This is due to the fact that people are different and think differently about their own image. But most of the time, they are filled with a desire that Delia, a senior in college expresses well enough in Am I Thin Enough Yet?:“ I always wanted to be the thinnest, the prettiest. ‘Cause I thought, if I look like this, then I am going to have so many boyfriends, and guys are going to be so in love with me, and I will be taken care of for the rest of my life” (qtd in Sharlene 7). According to Richard Rodriguez, there are complexions because the persons, who care for us like a family, are usually the ones who explain us that we have something to be ashamed of (441). On the other side, Bell Hooks thinks that all these complexions take their origin in the historical supremacy of the white race toward the black in particular (446). These are only a few examples of the probable reasons why people decide to change their look. But I personally think that people change the way they look in order to be attractive and appreciated. They believe that this issue can help in their search for happiness.
Organic inks, which are my personal professional preference, are the safest on the market. These types of inks are typically derived from plant matter. Vegan inks are also in the same class as the organic inks as well and are also ranked just as safe as organic inks.Organic inks are also safe to digest. I personally have no plans on digesting tattoo ink, but if I planned on doing so at least I know that it is safe.
Melanin helps reduce the absorption of wavelengths into the skin (Chaplin, Jablonski, 59). The more melanin in the skin, the greater the protection against harmful UV rays, and the amount of melanin in the skin correlates with the skin’s color (more melanin means darker skin)....
Colorism has became a huge issue in today’s society. Colorism is an issue because, it is a form of racism, it reflects back on the days of slavery, it is overall rude, and jail terms are affected.
Race and ethnicity are two terms that are constantly used in today’s society. Understanding these terms can help people to recognize that color of skin or color of hair does not define a person. These terms connect with history, social interaction, and the overall make up of a person. However America is constantly obsessed with labeling people by the way that they look or the way that they act. America seems to encourage the terms race and ethnicity and continue to divide people into categories. It is interesting to comprehend these terms because they are not going to disappear any time soon. Race and ethnicity are apart of America’s history and will be a part of the future.
