Whether you’re at basketball game or in the mall, you can see that people vary in size, skin color, and appearances. But did you know that no matter how different we all are as humans; we are just a single race. The variations that we see in everyday life are just physical differences but genetically humans are the same and “race” is term that has been used to distinguish human because of those physical differences. You may be wondering how one person from Canada and one person from Africa the same race, but it has been proven through the HGP (Human Genome Project). This project was led by scientist from all walks of the earth in order to try to understand and map the genetic structure of humans. They found that the term “race” is a false …show more content…
So in order to distinguish between groups they need a polymorphism that is located in all members of a group but missing in all members of another group. But humans have mixed too much for the differences to be present. Some polymorphisms have different frequencies and that is how they can roughly determine in which group a person belongs. They use a specific class of polymorphism that contains the Alus. Alus are pieces of DNA that are identical to one another. When an Alu infuses itself it will continue to stay there for generations, and it keeps getting transferred from one person to their offspring. So if they find two people with the Alu in the same location of each of their genome than it is certain that they have to be descendents from a common ancestor who also has the Alu in that same location in their DNA. There was an experiment held at the University of Utah, with a group of scientist, which used the 565 people and extracted 100 different Alus from each person. Their experiment concluded that they had 4 different groups of people. With this they discovered their country of origin and realized that to determine these they only needed about 60 Alus to have 90 percent accuracy. Some test concluded that some populations have experienced so much genetic influences that they cannot be placed into a specific group because of their genetic makeup.

Scholars say that the term race should not be used because it does not have any basis in scientific fact and really has no use today. According to the AAA’s statement on race, there is 94% variance in genes of individuals within one “racial” group. Race has its basis in colonization, when trying to conjure reasons why some groups of people, i.e. Native Americans and Africans, had lower places in society than the white people. That’s why the groups of “races” are so broad and meaningless today. The concept of race is just used to spread prejudice and give so called “scientific reasons” to discriminate against another group. The term
There is also a great deal of research done on genetic differences versus perception. It was even proven that the concept of race is merely a social construct and not nearly as scientifically in-tune as many believe it is. A study conducted by Eric D’Arcy of Harvard University in 2002 on alleles revealed a substantial observation on genetic differences between races and a socially constructed perception. Scientists found that, while alleles that were region-specific did show up, they really only appeared and occurred in numbers barely enough to construct any sort of trademark. In fact, they were found only in about 1% of the people of that specific region.
What is race? Some people attach "race" to a biological meaning, yet others use "race" as a socially constructed concept. “Most biologists and anthropologists do not recognize race as a biologically valid classification, in part because there is more genetic variation within groups than between them” (. So, it is clear that even though race does not have a biological meaning, it does have a social meaning - usually detrimental to our social harmony. Race is neither an essence nor an illusion, but
The idea of race in society is truly that; an idea. However, one of the first things one notices about another human is their perceived race. Often, incorrect assumptions are made about a person, based on his race. In addition, many believe race can be determined by biological factors. However, there is no biological basis to race. Without a doubt, genes play a role in our skin, hair, and eye color; however, there are not certain genes present in an entire race and not another. Race is not clear cut; if one were to travel from either pole to the equator, a specific location could not be identified to separate any two races.
The term "race" is a modern concept. It's definition has adopted radically new meaning over the past few centuries. Currently, the term is used to characterize differences among human groups. According to the Oxford English Dictionary the term "race" in 1512 is "a group or class of persons, animals, or things, having some common feature or
The principles of genetics and evolution show that race, biologically does not exist. The differences that appear in humans does not come from an allele that marks for a specific race. Usually most of the variations we see in humans comes from mutations that occur. The change in DNA is a major factor of variation in humans, it is something random which means certain attributes aren’t associated with a specific race. Another important thing to note is that all humans share the basic structure of DNA. This reinforces the idea that race is a social construct, not a reality of nature. Another main source of variation comes from gene flow (the movement of alleles to and from a certain location). Populations have always been moving from one place to another, and through this a trait can become more unique or more common. So there is less to do about
The English term ‘race’ is believed to originate from the Spanish word raza, which means ‘breed’ or ‘stock’ (Race). People use race to define other groups, this separation of groups is based largely on physical features. Features like skin color and hair don’t affect the fundamental biology of human variation (Hotz). Race is truly only skin deep, there are no true biological separations between two ‘racial’ groups. Scientifically speaking, there is more variation between single local groups than there is between two large, global groups; the human variation is constantly altering (Lewontin). The majority of today’s anthropologists agree that race is a form of social categorization, not the separation of groups based on biological
Race is a classification system used to categorize humans into large and distinct populations or groups by anatomical, cultural, ethnic, genetic, geographical,
Sociologist define race as a “socially defined category based on real or percived biological differnces between groups of people”. In the 19th century biologist came up with the three different categories that groups the three human races: Mongoloid, Causasoid and Negroid. They belived that different races where charaterized by biological makeup. But modern sciences have proved that theory to be wrong because there is no such thing as a “pure” race. We are 99.9% genetically idenitcal. Race is just a concept humans made up, it isn’t actually real.
To many people across a variety of different nationalities and cultures, race has been proven to be a key factor for how society views you in the eyes of those who are prominently in charge. The term race has been brought up in recent years, to be considered a form of identification, as the word race is used to describe physical characteristics such as a person’s color of skin, hair, and eyes. When in reality, the correct term they should be using is Ethnicity. As a result, the term race is used to separate people into sub-categories based on the color of their skin. This type of classification, is a man-made creation used by society to classify certain groups of people into lower classes, while keeping the predominate group in charge at the top.
The idea of race has been disproved due to lack of genetic variation within humans. There are not genetically distinguishable differences between humans, contradicting the idea there are subspecies as suggested by Carl Linnaeus’ theory of racial taxonomy (later taken up by Blumenbach in 1779 and expanded upon to categorise five races instead of four). Subspecies within the human race would require much greater genetic variation between ‘races’, whereas it has been determined that there is more genetic variation within a group of people than between groups of people. This can be attributed to the amount of time homo sapiens have
Due to scientist’s interest in human genetic variation, human racial classification became a focus of scientific investigation by evolutionary biologists attempting to categorize individual humans based on presumed patterns of biological difference. Scientists had hoped to classify humans in the same way that they classified other species. These scientists attached hierarchical titles to these categorizations; they claimed that differences in skin color, physiognomy, and geography were associated with scientifically measurable differences in character, aptitude, and temperament (Smedley, 1998). However, studies supporting these claims have been unsound (Gould, 1981). Categorization of humans by racial and ethnic groups continues, as researchers must remain aware of this historical legacy of the science of heredity as the genomic era continues to develop (Bonham et al., 2005).
What if you could design your child before it was even born? What if you could cut out any life threatening diseases, make sure that your child is not susceptible to smoking addictions or alcoholism, and then make your child genius? Would you? Are you asking yourself how this could be done? Have you ever considered human genetic engineering?
The human genome project is something that I have been very interested with ever since first learning of it. I had heard bits and pieces of what it is about, but my interest was greatly stimulated by Dr. Whited in basic genetics 311 last spring. The discussion that we had regarding the project left me with several ideas and questions about not only the process and ethics involved, but the future of the study of genetics as a whole.
Human Genome Project The Human Genome Project is an international project basically sponsored by the U.S Government. It started in October 1990 with an aim to sequence the entire human genome. The complete set of information present in the form of the genes in an organism forms its genome. Each human being has 23 pairs of chromosomes having DNA double helix in each.
