This is the fifth article in a series describing the subsequent chapters of the book "Draft of the Deductive Theory of Life" in a very short and accessible way. The titular integron concerns the level of organization of a theoretical object interpreted as alive (e.g. cellular, multicellular, colony of multicellular organisms), and not the structure within genetics. Subsequent levels arise gradually, at the same time selection at a higher level gains importance and natural selection at a lower level disappears, which is important in the controversial issue of group selection. Statistical mechanisms leading to the formation of higher-level integrons resulting from selection at different levels are indicated. During the process of integration, an exchange of hereditary information is created in the form of exchange of similar components of integrons, which leads to a strong acceleration of adaptation - the population mechanism and generative reproduction. A special case is the extremely probable integration of sister objects during reproduction, creating colonies. Maintaining optimized acceleration through the exchange of hereditary information at a lower level leads to the formation of ontogeny. The identified mechanisms of integration also describe biogenesis in terms of organization.
