Difference Between Hispanic And Native Americans

1. In modern times, anthropologists have come to realize that race is not a genetic difference between humans, and that we are all the same, yet differ by geographic origin. These geographic differences are what make humans appear different, which has yielded unnecessary and often tragic results in the past. Now, anthropologists study skin color and other “racial” differences to help identify humans for potential diseases or in crime scene investigation. In the paper written by Yann C. Klimentidis, Geoffrey F. Miller and Mark D. Shriver, Hispanic and Native American populations were surveyed and studied to find how their believed genetic background differs from their actual genetic background. The results of their work could be used to better …show more content…

A variety of statistical tests were synthesized to analyze all the data acquired in the methods section. Initially, a Mann-Whitney test is used to display the results of the self-identified race vs the genetic test of race, which showed that most individuals underestimated the percent of their respective genetic heritage. For comparing actual percentage of Native American genetics in individuals who claimed to be Hispanic, R squared tests were performed. In general, if Native American heritage was self-identified, it showed up in some amount on the individual’s genetic test. The survey that asked student to identify their own races yielded similar results; most students were accurate with their self-identifications. Next, the authors compared self-estimate Native American admixture with genetic admixture with a Spearman correlation model. The results were mostly positive, with individuals again being able to somewhat accurately predict their genetic background. However, there were many individuals that predicted that they were no parts Native American, while their genetic testing revealed up to 75% Native American genetic relation. The authors explain that there is a bias; because the tests were done on a proportion of 0-100%, there could be individuals that are over 100% or under 0% genetically Native America, leaving them undefined and not in the graph. Finally, skin pigmentation of the upper arm was more useful in analysis than forehead pigmentation, as in an area with …show more content…

In the discussion section the authors suggest that their study reveals that Hispanics and Native Americans “underestimate” their amount of mixing with other ethnic groups. This point is solidified by the results of the genetic testing compared to the student’s self-prediction of their own genetics, as some students thought they had 0% genetics shared with Native Americans when in reality all had some. The author’s analysis adequately answered the research question and provided information and insight to social vs actual representation of race in current times. In the conclusions section of the paper, the authors state that “This study demonstrates that the relationship between genetic and socially based measures of identification can be confounded by historical, cultural, social and perhaps phenotypic factors.” This sentence alone sums up the idea of the paper well, showing that the social side of race can be based truly on just appearance for most individuals and not actual genetic heritage. In areas where disease is more predisposed to certain genetic factors, presumption that an individual is more likely to get a disease based on physical appearance can likely be incorrect. At the end of the conclusion, the authors, like in many other scientific papers, state that more research is needed to have a more precise and viable
