Mixed Race Studies

Scholarly perspectives on the mixed race experience.

One of [Richard] Lewontin’s pathbreaking works was to find out how much genetic diversity exists within species. This was at a time when we did not know how many genes humans had. Lewontin’s inspired guess was 20,000, far smaller than what most biologists thought then and remarkably close to what is known today. Most biologists then also believed that races had significant biological differences, which was one of the reasons why they thought that there was a much larger number of genes carrying different traits. Lewontin and geneticist John Hubby used a technique, protein gel electrophoresis, developed by Hubby, to quantify the genetic diversity in fruit flies. At that time, fruit flies were the favorite target for testing genetic theories in the laboratory. This pathbreaking exercise traced evolution at the species level to changes at the molecular level—a foundation for the field of molecular evolution—using statistical methods. The result was startling. Contrary to what most biologists believed, the exercise showed a surprising amount of genetic diversity within a given population and further revealed that evolution led to stable and diverse populations within a species. Later on, Lewontin used this method on human blood groups, to show that the result of stable genetic diversity held true for humans as well. The other result of the human blood group study was that it showed that 85.4 percent of the genetic diversity in humans was found within a population, and only 6.3 percent between ‘races.’ Race was not a biological construct but a social one.
