Evolucionismo y liberación

The unilinear evolutionary theory, which conceives the evolution of humanity as a natural process, parallel to the biological one, in terms of which all societies must necessarily and chronologically pass through identical stages to finally reach the same degree of development, was set aside in the light of later discoveries demonstrating that this theory was based on partial observations of reality and their generalized application, leaving aside aspects of human development that showed that not necessarily the whole of humanity would progress toward the model of European civilization. This type of evolutionism had as one of its central points, following Darwin's work, a parallel between the natural evolution of the species and the historical evolution of humanity. "Thus, for Margan, the history of historians is only an appearance masking an evolution whose forms and modalities are exactly identical to those of natural evolution."
