Evolution is nature's so much attention-grabbing strategy, the prospect given adequate time to mix uncomplicated inorganic compounds to an increasing number of advanced biochemical compounds, which make up a growing number of complicated organisms. it really is for that reason the most important in our attempt to appreciate the evolution to work out it from as many alternative angles as attainable. This books draw a picture of evolution from the thermodynamic standpoint, which provides new and fantastic insights into the approaches and mechanisms that experience pushed evolution. This new thermodynamic interpretation has made it attainable to quantify many of the steps of evolution and to teach that evolution has an exponential progress curve. *The first finished thermodynamic interpretation and rationalization of evolution *This thermodynamic interpretation makes it attainable to quantify a number of the steps of evolution *This interpretation explains the large spectrum of other mechanisms on which the evolution has been dependent

Example text

In ecosystems the ultimate exergy influx comes from solar radiation, and the order induced is, for example biochemical molecular order. If deEx > ÀdiEx (the exergy consumption in the system), the system has surplus exergy input, which may be utilized to construct further order in the system, or as Prigogine (1980) calls it: dissipative structure. The system will thereby move further away from the thermodynamic equilibrium. The evolution shows that this situation has been valid for the ecosphere on a long-term basis.

Growth form I covers attributes 1, 3 and 7. The biomass increases according to attribute 1, which implies that also the respiration increases, because it costs more exergy to maintain more biomass. This means that also the entropy production will increase. Growth form II covers 2 and 6. When the network increases, there will be more feedback mechanisms available for regulation of the network. The energy and mass will thereby circle to a higher extent which means that more biomass can be supported with the same total input and output of the eco-exergy.

It means that entropy þ information = constant. When we gain information, entropy decreases, and when we loose information, entropy increases. The constant expresses the total information needed to know all the details of a considered system. When we have the full information about the considered system, information = constant and entropy = 0. When we have no knowledge at all about the system, the entropy = constant and information = 0. 09 10À17 J/K. The entropy is the disorder resulting from 1,000,000 signs selected among 40 possible types.
