I. Prigogine Investigation

Prigogine InvestigationAbstractThe origination and evolution of spirit organisms is considered by many scientists , delinquent to general fairnesss of nature , especially the second law of thermodynamics . In this this idea is explored , taking in account the dissipative structures and Prigogine s thermodynamicsIntroductionThe use of thermodynamics in biology has a tenacious history rich in confusion (Morowitz , 92 (Klyce , Brigg , HYPERLINK http / web .panspermia .org /seconlaw .htm http /www .panspermia .org /seconlaw .htm ? 0 (Gibbs , 1928 . exclusively , in case of evolution , the animation schemas increasingly go on to complex avow of much , suggesting that mho in this closed trunk has decreased . This is the riddle that has baffled both(prenominal) biologists and physicists alike . indeed , an initial guess wh ich both physicists and biologists concord upon was : lifespan violates the second law of thermodynamicsEvolution of life and EntropyThe contradiction displace however be explained , by subscribing to one of the two very(prenominal) different schools of thoughtEither we throne accept that the that is seen in the evolution and maturement biological systems is makeed at the disbursement of thermodynamic . That is to say , sustenance in the form of away energy is eternally provided to the organism from outside(a) purlieu and data of this larger system is increasing . Hence , living beings rive negative stochasticity , in to requite for this amplification in the randomness , which explains the . This concept was formed by SchrtzdingerThere is another story , which was proposed by Prof . Ilya Prigogine . According to him , the living organisms buy the farm as dissipative structures , i .e . thermodynamically open systems direct in non-balance environment . These ha ve the capacity for self-organization in the! face of environmental fluctuations .

In other words , they maintain their structure by continuously dissipating energy Such dissipative structures ar permanently in call forths of non- sense of equilibriumDs /dt 0 away from steady stateDs /dt 0 steady state (Prigogine , 1977In this case , equilibrium is the state of supreme entropy . A system that is not in equilibrium exhibits a translation of entropy , which is the sum of the renderings of entropy due to the internal ancestor of entropy , plus the variation of entropy due to the fundamental interaction with the external world The cause is cocksure , but th e latter(prenominal) can be negative . thus , entropy of the system can decrease . Life gibe to this theory can then be summarized as : An organism lives because it absorbs energy from the external world and processes it to generate an internal state of lower entropy . It can live as long as it can avoid falling in the equilibrium stateAccording to the second law , only irreversible processes contribute to entropy production . This subject matter the existence of a function in an isolated system which can only increase in time . It follows that the positive time direction is associated with entropy (Prigogine , 1977Now , biological evolution is class-conscious and can be considered as an irreversible process of the variation of life with respect to the evolutionary time scale .
