The study is grounded on information as a property of the constituent elements of both material and non-material systems. Through these interactions, a function is performed, or a structure is formed, which in turn performs a function analogous to the behavior of an intelligent agent. Information and self-organization give rise to modules at the molecular, cellular, and individual levels. Species, likewise, can be understood as modules, real and objective units of life, that emerge as cognitive, linguistic, and biological modules. In the framework of the biological module concept, species can be viewed as a temporal chain of living organisms, where each link comprises three successive populations that behave among themselves as intelligent agents. The intelligent agent is zygotic information in sexually reproducing organisms and an affordance of the environment in asexually reproducing organisms. However, a new model has been developed in which the stability of the species is argued, analogous to the stability observed in other biological modules.
