Indian Skin Pigmentation Of India

Geographical isolation in the past has caused a variation in skin color; natural selection selected specific skin pigments depending on environmental factors. Early humans who moved to Europe were introduced to a place that had less sunlight than their former place of residence. Overtime, light skin (skin with lower levels of melanin) was selected for since there were not as many UV rays that the skin needed protection from. But, what was wrong with having dark skin in Europe? How is extra melanin a disadvantage in this case? One thing to remember is that even though the sun can provide UV rays, sunlight is also a great source of natural vitamin D (Jablonski; Kirchweger). Vitamin D helps bones absorb calcium and is particularly essential for developing embryos in pregnant women. The adaptation for lighter skin was important because the skin needed to absorb as much sunlight as it could in order to receive optimal amounts of vitamin D (Kirchweger). However, too much vitamin D can be fatal. So as high amounts of melanin protected the skin from excessive UV rays in Africa, they also protected it from excessive vitamin D (Kirchweger).

In 1991, Jablonski came across a paper written by Richard F. Branda and John W. Eaton, in this paper they showed that people with lighter skin that had

In the book, Color of man written by Robert Cohen, he said that our skin color is determined by the amount of melanin pigment in our skin. Dark skin has a lot of melanin while Lighter skin have less. Although, the difference in our skin are very real, anthropologies long ago rejected the idea of races connected to skin color because it was believed that there is no culture in color, no muscular or mental abilities connected to melanin, no character trait, virtue or values associated to skin color, yet at an early age children are learning their color and the differences between other kinds. What parents refuse to teach their kids is why we have different colors and what melanin is but instead kids are taught an eternally different thing. Recent studies have shown where children get their racial ideas from, Ali Michael and Eleanor Bartoli described what was found in a study of white parents and their white

Caucasians have the lowest amount of melanin in their skin cells when being compared to other cultures. Melanin is crucial to protecting our skin from UV rays, and so someone with a darker skin tone is better protected.

5. In the film, Dr. Jablonski explains that melanin, located in the top layer of human skin, absorbs UV radiation, protecting cells from the damaging effects of UV. Genetics determines the type of melanin (i.e., brown/black eumelanin or red/brown pheomelanin) and the amount of melanin present in an individual’s cells. Based on this information, write a hypothesis for where in the world you would expect to find human populations with

Additionally, there is a substantial lack of real evidence that the divisions between groups that we often specify as “races” actually have specific genetic identities. The extreme presence of ambiguity central to races, and the plentiful variations within these races point towards evidence that even two randomly selected citizens of European descent could be more genetically related to a person of Asian descent than they are to each other.

The PBS series “Race: The Power of an Illusion” effectively works to expose race as a social construct and deconstructs the false notions that race is a biological marker. The series first discusses that all human beings originated from Africa but dispersed about 70,000 years ago to various places in the world. As a result of this migration, people were spread to different locations throughout the world with different environmental conditions that affected their physical traits. It was many years after the migration in which people began to display these new physical traits such as slanted eyes, fair skin, and differing hair textures. While the series notes the physical changes that occurred during the migration it also emphasizes that race while it may seem apparent in skin color and other physical features has no real biological basis.

As the research continues it becomes ever more important to discuss how exactly the differing pigmentation of one race of people actually occurs, because I feel that it has an effect on the way colorism is handled throughout the African American community. There are two ways in which a person of African descent can be of a lighter complexion; the first being amalgamation, which is the coming together of both the black and white races and reproducing to make a mulatto or mixed race child and the second is the use of cosmetic creams in attempt to bleach one’s skin until they too appear mulatto (Dorman 48). This is relevant because, it shows the extremes that people are willing to go to reach the highest plateau of social acceptance. Many of these creams were painful acidic chemicals slowly burning away the pigmentation as people slept, while others were considered mild abrasive materials used to “gently” scrape away dark pigments (Dorman

Numerous studies have proven to show that there are genetic differences between racial groups as noted in the article, “Racial Disparities Noted in the Immune System” by ScienceDaily. The study showed different gene

Physical features do not always explain the person’s descent. They could have many different cultures and not even know they have one of them. People believe everything they hear without doing any research on the matter. People ignorantly say that they are strictly one race. They do not understand they can have multiple descents. In the article “Why Race Isn’t As “Black” and “White” As We Think” by Brent Staples, he explains “The result that knocked me off my chair showed that one-fifth of my ancestry is Asian.” (Staples 325) This shows how little people know about themselves. Most people go based off their skin color; this is why people do not do any research on the

The tests for normality, examining standardized skewness and the Shapiro-Wilks test indicated the data were statistically normal for origination rates. However, the Levene's F test revealed a violation of the homogeneity of variance assumption by race was not met for female originations (p = .025). As such, the Welch's F test and the posthoc James-Howell procedures were used. The results presented in Table 4 capture the one-way ANOVA for the race effect on origination rate. For females, the one-way ANOVA revealed a statistically significant main race effect on origination rates, Welch’s F(4, 9.87) = 30.07, p < .001, ω2 = .83. Omega squared has shown approximately 83% of the total variation in females’ origination

The skin tones represented were pale, tan, brown and dark (Swami et al., 2008). There was also a constant color for hair color, which was black. The swimsuit color remained unchanged as the color white. The participants were anonymously emailed the survey.

The MC1R gene plays an important role in determining if a person has red hair, fair skin, and sensitivity to UV radiation, it also regulates the synthesis of melanin. MC1R is more common in Northern European countries posing a greater risk of skin cancer to those who have high exposure to ultraviolet rays. People who have olive and darker skin and who carry one or more variations of this gene have a higher than average risk for melanoma. The MC1R gene, which being whiter – ‘fair skinned’ is also associated with an increased susceptibility to melanoma.

Not unlike early, but modern humans, the humans of today are also varied. Skin color is one of the most obvious difference among humans today. There are Caucasian, white skinned people, Negro people with black skin, “red skinned” Native Americans, “yellow skinned” Asians, and “brown skinned” Indians. And even among those many groups, the skin color can vary. Mixing of Negro and Caucasion for example produces a skin color similar to cocoa. Not black, but not white. When humans were first categorized into race, there were five basic races that were defined simply as white, yellow, red, black and brown. Now, it's no longer that simple or concise. Through interbreeding, humans now come in many varieties of skin colors. Eye color is also a modern human variation that depends on genetics to determine the color your eyes will be. Hair color and texture is another variation that again, relies on genetics to determine. And internally, a human's blood type is also a variation, though, there are only a few

For a long time, the term “albinism” referred only to people who had white hair, white skin, and blue eyes. Individuals who had OCA and pigmented hair and eyes were identified, particularly in the African and
