Decline of Racial Studies After 1930

Several social and political developments that occurred at the end of the 19th century and into the 20th century led to the transformation in the discourse of race. Three movements that historians have considered are: the coming of mass democracy, the age of imperialist expansion, and the impact of Nazism. More than any other, the violence of Nazi rule, the Holocaust, and World War II transformed the whole discussion of race. Nazism made an argument for racial superiority based on a biological basis. This led to the idea that people could be divided into discrete groups and based on the divisions, there would be severe, tortuous, and often fatal consequence. The exposition of racial theory beginning in the Third Reich, up to the Final Solution, created a popular moral revolution against racism. In 1950, and as a response to the genocide of Nazism, UNESCO was formed and released a statement saying that there was no biological determinant or basis for race.

Consequently, studies of human variation focused more on actual patterns of variation and evolutionary patterns among populations and less about classification. Some scientists point to three discoveries. Firstly, African populations exhibit greater genetic diversity and less linkage disequilibrium because of their long history. Secondly, genetic similarity is directly correlated with geographic proximity. Lastly, some loci reflect selection in response to environmental gradients. Therefore, some argue, human racial groups do not appear to be distinct ethnic groups.
