The history of biology in Mexico has focused largely on showing the impact that theories like Charles Darwin's had during the late 19th and early 20th centuries. Recently, there has been an attempt to broaden the scope of this research by highlighting the impact of other visions such as those like Herbert Spencer's - fundamental in Mexican education and politics - and Francis Galton's - of importance in the institutionalization of eugenics in Mexico. However, an issue that has not been addressed is that of anarchism, which has taken up biological/evolutionary proposals (from authors such as Herbert Spencer himself, Piotr Kropotkin, among others) to found a basis for a revolutionary discourse that sought an authentic change in Mexican society. Another example, the French geographer Élisée Reclus, who maintained that "Science did not establish any difference between the words of evolution and revolution", both of which reflected, according to Reclus, in a continuous way, the infinite movement of transformation of the universe, of nature, of life, of species, of society, an interpretation shared by other authors, which Flores Magón brought together in the so-called Sociological Library of Regeneration.
We want to focus this paper on the discourses that appeared in the anarchist newspaper Regeneración (Regeneration), which was edited by the Mexican revolutionary Ricardo Flores Magón. Through various examples, we want to show the influence of the biological/evolutionary theories that served Flores Magón to articulate a revolutionary discourse that distinguished itself from others by seeking authentic social change, based on biological change.
