 The traditional topic of natural selection is treated in relation to its explanatory power by Pablo Lorenzano in collaboration with the Spanish philosopher José Díez (Díez and Lorenzano 2013, 2015). Santiago Ginnobili (2016) offers a metatheoretical structuralist reconstruction of Darwin’s theory with the purpose of elucidating the concept of ecological fitness, and Mario Casanueva (2011) proposes a structuralist reconstruction of the mechanism of natural selection by means of graph resources. In turn, Gustavo Caponi (2013) studies the concepts of function, fitness, and adaptation in natural selection theory.
