Some landmarks are proposed here to study homologies or breakings while modeling natural phenomena in physical or living world. Diversity is life characteristics, and linking diversity and modeling is not straightforward. It is addressed here with algorithmic complexity of data sets. Observed regularities in living systems seem to be due to statistical regularities from law of large number rather than to universal processes yielding the same pattern repeatedly. The link between processes and pattern is weaker in living systems than in physical systems. In biology, a pattern is the outcome of history, of evolution. Current modeling techniques in ecology work with “here and now” conditions, or “there and now” conditions through interactions. Therefore, there are not sufficient. In biology, current state includes the memory of the past, encapsulated within DNA molecule, whereas in physics, current state usually is sufficient to predict the future with dynamical systems. Thus, a relevant purpose of modeling in biology is to build genealogies, i.e. reconstruction of history. This historical approach takes into the past as the theater where current diversity of living world has been built by evolution processes. It is one of the major breaking-point between modeling physical world and modeling living world.

En utilisant une partie méconnue des suggestions d’Erwin Schrödinger publiées dans son fameux Qu’est-ce que la vie ? (1944), l’auteur rappelle, dans un premier temps, qu’à l’heure de [1] Les résumés de Longo, Keller, Lassègue, Noble, Gandrillon, Mazat, Walliser donnés ici sont en fait extraits de l’introduction rédigée à l’époque par Marc Silberstein & Franck Varenne pour le numéro de la revue Matière première consacré en 2008 à la modélisation, la simulation et la biologie des systèmes (voir le NB de l’avant-propos). © Editions Matériologiques, 2013.
