In Omi and Winant, Racial Formation the topic of what race is brought up. They bring up the question of "What is race?" Which lead to the use of pseudo-science to justify the physical difference that were observed. Race is later defined as a social construct which is shaped by broader societal forces.

16. Human populations living in areas of intense sunlight tend to be darker skinned because of the

Scientist found that 85% of genetic differences occur within racial groups and the other 15% occurs between them. (Journal of Human Biology 2009)

In a film of “Race the Power of an Illusion, Part I The Difference Between Us”, it talked about the differences of races such as skin, eye, hair color. However, in our genetic, the human is not very different than we think but we had a similar genetic code. In the 1950s, the athlete champions were all black, and they were much better than any other. Maybe because of that some people think there are different structure bodies than other races. In this case, I think it could make sense that black people have better body structure than white. However, it is the wrong stereotype about skin color. The skin tone is continuously changing, and the reason why a human has different physical appearances is that of different genes we have. Depends on the

From a biological perspective, race is a social construct that has little bias in genetics. In the PBS documentary, episode 1: Race: The Power of Illusion, Microbiologist Pilar

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.

This is interesting to me in that though everyone looks different, we are al vary similar at a the DNA level. Our differences are not so great. There are two historical perspectives on race and ethnicity among geneticist. One is that is a cultural and historical construct with no biological significance, meaning that there is entirely unique to a particular ethnicity. The other argument is that there are biological differences between different ethnicities. As the human genome was being sequenced, different frequencies of genes variants related to disease susceptibility, drug metabolism, and environmental response were found among different populations (). Even though there is a small difference in DNA from person to person, there is some biological distinction. The variations of these genes tend to be similar among certain

Sickle cell disease is a disease that is most prevalent in people of African descent along with people of Mediterranean and Middle Eastern origin. This disease is known to affect about 70, 000 Americans and about 2 million people carry the trait (meaning that, they carry a single gene mutation).

Biological anthropologists have researched that humans evolved mostly in Africa, where they originated. I also agree with this since there are many fossil records of early humans, and more modern humans in Asia, Europe, Australia, and the Americas. As time passed, they evolved, climate changed, and natural selection occurred. With this climate change, populations fluctuate and mutations occur between generations. As you will see, humans have gone through much natural selection to be who we are now. More natural selection is also occurring now faster than ever and will in the future.

Genetically, they are uniform, but their environment can create explicit differences. One may have darker hair, or in more extreme nutritional variation: one may be taller than the other. This is not a matter of genes, this is a matter of resources. Access to care in the region, insurance status, and immigrant status create a health concoction. Health is a matter of intersectionality. No one factor negates the necessity of another; however, when comparing zip code to genetic code, zip code can often be the difference between thriving and

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

3) If the current population is evolving, what type of effect is responsible for genetic drift?

Two theories explaining the origin of humans are popular today among evolutionists. The first theory, multiregional continuity model states, modern humans evolved from several different groups of hominids that interbred at some point at produce modern humans(Actionbioscience.org, 2017). Multiregional continuity contradicted the ‘out of Africa’ theory with the data and the evolutionary development within the homo-species and its culture use and fossil findings. The evolutionary development of the brain in hominins was associated with increasing social complexity and the development of what we know as culture. Culture can be believed as the accumulation of knowledge, rules and mental abilities that humans utilise in order to survive. Obtaining

Sickle-cell disease is more common among people whose ancestors lived in tropical and sub-tropical sub-Saharan regions where malaria was common. In other words, being a heterozygote is advantageous as specifically, humans

The human race as a result of its dynamism, roots, ability to adapt, acute intelligence, amongst other characteristics possessed, is undoubtedly the most unique of all earthly existence. One of it’s amazing characteristics is the peculiarities common to a group of people occupying a particular territorial area; races as they are popularly referred to as. Individuals belonging to each of these races are known to possess similar physical features such as skin color, body proportions, hair structure amongst others. Members of the Caucasian ethnicity are known to possess light skin, straight or wavy light or dark brown hair, gray, gray-green, hazel and wide open blue eyes, moderately developed chin, a narrow protruding nose, thin lips and facial hair for men; Mongoloids possess a yellow or yellow-brown skin, dark straight hair, broad faces, narrow and slightly slanted brown eyes with a fold of the upper eyelid in the inner corner of the eye (epicanthus), flat and rather broad nose, and sparse vegetation on the face and body while Negroids on the other hand are usually dark-skinned possessing curly dark hair, broad noses, brown or black eyes with sparse vegetation on the face and body. Popular explanation by some scientists claim that racial features peculiar to a particular race are as a result of our independent origin from different ancestors in different places. Others
