Bio-geographic DNA markers are special cells that contain our DNA that contain special code that is unique to specific areas of the world, called Single Nucleotide Polymorphisms or SNP for short. It is with these SNPs that we can find the differences and similarities between other people in the human race.
Although the ones that are specifically keyed to our so called “race markers” are best described as Ancestry Informative Markers. It is with these key segments of our DNA code that researchers are able to identify our past ancestry dating back thousands of years, to find out that we had a great great great great great grandfather who had East Asian blood in someone, despite looking 100% European.
During much of history we have discriminated each other based on each other's “race” based upon their country of origin via physical characteristics. Although in more modern times we have found that our definitions of race, calling someone African American, because they have dark skin isn't necessarily so accurate. Through the modern discovery of genetics, we have found that there are fewer differences between the so-called races, and then there are within each race, despite popular opinion that likes to think otherwise.
Society would call me “white” or “European” because of my red hair and white skin, yet my DNA shows that I am also Asian by approximately 2%! All of these facts come together to prove that race is not a concept of genetics as we have been previously taught, but a construct of societies meant to keep us further apart, instead of coming together as a whole.
I do not believe that my DNA test results show much, if any, positive results for the Complete Replacement Model. Considering the fact that my DNA test results had 0% African American, with a maximum amount of 2% at the very most for the margin of error. This makes it harder to believe that I had distant relatives who lived in Africa and later migrated over to Europe. If my DNA test results had shown that I had a higher amount of African ancestry in me, even to the point where I had 1% I'd be a little more likely to believe it. Although on the other hand it could merely mean that the bloodline of my African ancestry has been so far diluted over the countless millennia that it would be far too hard to find a reasonable amount of to make a clear linkage to a past ancestor in Africa.
In terms of the Regional Continuity Model I think my DNA test results show a much stronger tie to that theory of early humans. My DNA is almost entirely, 98%, European. This tends to give rise to the thought that my ancestors did not start in Africa and then migrate to Europe, but instead started in Europe and migrated elsewhere.
Biological Determinism holds a stronger case for the Regional Continuity Model then it ever does for the Complete Replacement Model. If we all had descendants from one original place, then it makes no logical sense to believe that people are more morally corrupt or intelligent because of their race. If everyone in the world came from the same original gene pool, then our differences would only be skin and culture deep. However, if we were to look at each race developing separately, then you would have a lot more cause to think that there might be differences of intelligence or morality between each race. Although even then that's rather limiting, without studying more then race, but living conditions, culture, and other influences that might cause differences.
Personally from my own genetics, I view that traditional concepts of race and racism do not apply in our more modern society. Many of these people who claim to be pure in race, are almost always not as pure as they had believed. A member of the KKK may look at me and think me pure, but my DNA says that I have 2% Asian blood in me. Therefore to make any sort of judgments about someone's race as a predicator of someone's intellectual or moral reasoning, will find that science has a much different way of looking at things.
We are no longer a “pure” race, as even with Europeans, we have mixed from England and Germany and many other various European countries. It seems folly to try to say that one's race will have anything to do with a person's morals or social status.
