Abstract

Towards an evolutionary thermodynamics of ecosystems E. Tiezzi & N. Marchettini Department of Chemical and Biosystems Sciences, University of Siena, Italy. Abstract The epistemological and thermodynamic bases to proceed towards an evolutionary physics are presented, having in mind the new theories of the Bruxelles's school (llya Prigogine). Namely the relationship between evolutionary thermodynamics and complexity of ecosystems has been taken into account, focusing the attention on the role of time, emergence and creation of events. Energy vs. entropy is discussed in more details, in terms of dissipative structures and Prigogine's thermodynamics. 1 Introduction Biological activity is a planetary property, a continuous interaction of atmospheres, oceans, plants, animals, microorganisms, molecules, electrons, energies and matter, all part of a global whole. The role of each of these components is essential for the maintenance of life. The relations
