Biomedical knowledge in Mexico during the Cold War and its impact in pictorial representations of Homo sapiens and racial hierarchies

Abstract This paper provides an overview of the state of Mexican genetics and biomedical knowledge during the second half of the twentieth century, as well as its impact on the visual representation of human groups and racial hierarchies, based on social studies of scientific imaging and visualization (SIV) and theoretical concepts and methods. It also addresses the genealogy and shifts of the concept of race and racialization of Mexican bodies, concluding with the novel visual culture that resulted from genetic knowledge merged with the racist phenomenon in the second half of the twentieth century in Mexico.
