 The role played by models in science was studied in Latin America since the first years of the twentieth century. In México, Alfredo López Austin (2005) compiled a volume including five contributions that explore the meaning and the nature of scientific models. Recently, Mario Casanueva and Ximena González-Grandón (2016) edited a special issue of the journal Scientiae Studia, whose articles fall into two groups: those in the first group emphasize that models amplify our capacities of representation, perception, and calculation; those in the second stress the function of models in legitimating scientific knowledge.
