Réseaux et genèse de la forme: perspectives épistémologiques

Our paper focuses on Stuart Kauffman’s theory from 1993 to 2004. Kauffman is looking for an explanation of the genesis of living beings by genetic networks. From interactions to cell types, Kauffman’s viewpoint is concerned with differentiation and self-organization as network’s properties. His approach of morphogenetic processes is interesting but it is insufficient. According to Sole, Fernandez and Kauffman [2003], networks would give an explanation of the diversity in patterns and cell types. Some other authors [as Perkins et al., 2004] consider that it is necessary to explore interactions, not with logical methods only, but non-linear systems too. Network’s structure is related to biological diversity. It supposes genes’ power’s mediators within the cells and between them.
