Besides the two most well-known cases, the local bifurcations of the saddle-node and Hopf type, biochemical systems may show a variety of transitions between qualitatively different dynamic behavior [13, 17, 293, 294, 297 301]. Transitions between different regimes, induced by variation of kinetic parameters, are usually depicted in a bifurcation diagram. Within the chemical literature, a substantial number of articles seek to identify the possible bifurcation of a chemical system. Two prominent frameworks are Chemical Reaction Network Theory (CRNT), developed mainly by M. Feinberg [79, 80], and Stoichiometric Network Analysis (SNA), developed by B. L. Clarke [81 83]. An analysis of the (local) bifurcations of metabolic networks, as determinants of the dynamic behavior of metabolic states, constitutes the main topic of Section VIII. In addition to the scenarios discussed above, more complicated quasiperiodic or chaotic dynamics is sometimes reported for models of metabolic pathways [302 304]. However, apart from few special cases, the possible relevance of such complicated dynamics is, at best, unclear. Quite on the contrary, at least for central metabolism, we observe a striking absence of complicated dynamic phenomena. To what extent this might be an inherent feature of (bio)chemical systems, or brought about by evolutionary adaption, will be briefly discussed in Section IX. [Pg.171]

And now, when at the stage of the noosphere, which is a stage of the revolutionary reorganization of the whole process of the planetary development, the determining factor of evolution is human activity, we should realize that Mind becomes a participant of the evolutionary process, exactly the participant which with all its power follows the common laws. And under such conditions, considering all limits, barriers inherent to Nature, we have the right to speak about the directed development of the biosphere. ... [Pg.109]

The threats posed by ice formation in the intracellular and extracellular fluids have favored selection in diverse types of organisms for mechanisms that either prevent the formation of ice or minimize the potential for enlargement of any small ice crystals that do form in the internal fluids. These mechanisms are under intense study, both because of their inherent interest to evolutionary and ecological physiol-... [Pg.406]

Evolutionary optimization then is not just a blind stochastic trial-and-error search for a better adapted mutant but rather follows an inherent logic ... [Pg.234]
