The Holocaust’s discrediting of eugenics, not prior scholarship, ended biological race science.

Evidence

Although black scholars like Kelly Miller, William Monroe Trotter, and W.E.B. Du Bois had questioned biologistic racism at the end of the 19th century, and Chicago sociologists had cast doubt on evolutionbased accounts of racial difference in the 1920s, it was not until after World War II that a sustained attack on the notion of race as a biological concept emerged and gained widespread acceptance. Only after eugenics had been discredited as the basis for racial science in Nazi Germany— eugenics had, of course, flourished in the United States as well— did scientific critiques of biologistic racism become prominent. — Michael Omi, Howard Winant, Racial Formation in the United States, 120
