Human Variation and Race

Does skin color tell us anything about a person’s cultural or individual identity?

In our society we seem to easily classify individuals based on racial stereotypes. Cultural anthropologists have been able to determine real biological differences in humans which explain the reasons why people in different regions of the world have varying skin color. The study of how and why the physical traits of human populations vary across the world is known as the study of human variation.

According to geneticist Jeffrey C. Long, “None of the observable traits that

people associate with race are simple genetic traits. Complex traits are influenced by several genes as well as environment.” There seem to be only subtle changes in the genetic makeup of humans from one place to another. Anthropologists’ have explained this simply as a consequence of people marrying those who live near them versus marrying those who live across large distances. An example of this is how several generations of families seem to share many of the same inherited traits. (the American Anthropological Association, 2011)

To begin the process of understanding why there are distinct patterns in the genetic composition of people from various regions, biological anthropologists gather data about genetically inherited traits. Tests such as blood typing and DNA sequencing have given researchers very detailed information to help understand the biological diversity of humans.

Most of our DNA is passed on as a pairs of chromosomes-half of each pair from the mother and half from the father. Each parent also has a special type of DNA that is exclusive to them that they then pass to their offspring. Mothers pass on Mitochondrial DNA, while Y-chromosome DNA is passed do...
