L'ordine naturale celato nell'auto-organizzazione biologica

Ilaria Cinelli


The article is an analysis of the theme of life; the survey content is not confined exclusively to a scientific perspective, you can see a weave with philosophical reflections. In an attempt to give a satisfactory definition of life, some more appropriate terms have been introduced in the discussion such as information and perception and meaning. The starting point are the issues addressed by Monod, which shows that the basis of the regulatory capacity of the living – which requires the combination of three features: teleonomy, autonomous morphogenesis, and reproductive invariance – there is a total gratuity, or an arbitrary relationship that is established between a substrate and an allosteric enzyme and the ligands that activate or inhibit its activity. In contrast with the consideration Monod regarding the origin of life, it ranks the position of Ilya Prigogine, the aim of his research is to demonstrate the fact that the emergence of life is not a highly unlikely event whose training was almost nothing, but an event that occurs when the chemical-physical characteristics allow it, or you can see the emergence of life in a condition of equilibrium distance. The systems far from equilibrium and open towards the surrounding environment, in which fluctuations can produce order out of chaos are called dissipative structures. Starting from these considerations, the American biologist Stuart Kauffman investigates in more depth the self-organization principles which are common to all complex adaptive systems, is equivalent to saying sets of elements united by a dense network that are capable of interacting with each other, having also the ability to adapt to changes even from outside. Self-organization according to biologist along with natural selection can explain the phenomenon of life in its extraordinary complexity.
