snoopdogg Posted December 12, 2009 Report Posted December 12, 2009 Well, my problem is, given the context of the thread, I have no clue by what you mean by the word "symmetry". Even your description in an earlier post did not help at all. Perhaps you could be more explicit. Pyro See Noether's theorem (which, in greatly simplified form, states that for every continuous mathematical symmetry, there is a corresponding conserved quantity. It is this conserved quantity that passed information from a simple form to a complex form. Symmetry allows for such complex systems such as evolution to persist without violating 2LOT. As the forest grow and becomes more complex on a macro level, it really only follows natural paths of symmetry on a micro level. This in terns leads to greater entropy although perceived as complexity. Quote
nevaeh.aaric Posted February 9, 2010 Report Posted February 9, 2010 Life and evolution don't play by these rules in every sense. If we start with simply RNA replicators, and move toward a simple integrated cell precursor, and do an atom by atom assessment, we are going from the high degree of disorder of chemicals in solution into definitive order. Evolution is a state of non-equilibrium which is changing over time. But life becomes more ordered.Random changes in the DNA will increase the entropy of the DNA, since improper base pairing creates defects within the original order. If this entropy increase projects into increasing cellular entropy, so the cell is losing all sense of order, it dies. Then the second law would be satisfied. But life avoid this if possible. Evolution requires this initial disorder or entropy, lower or become integrated into a new cellular order. Eventually even the DNA defect or entropy, is not a defect, but part of the new DNA order.

Entropy is not a measure of "disorder". This is a common yet misleading high school physics mistake made by either incompetent or lazy teachers. Disorder — A Cracked Crutch For Supporting Entropy Discussions But life becomes more ordered. "Life" is an ordering of atoms, but in order to remain ordered :) , life INCREASES entropy readily as all living things are dissipative structures. Dissipative system - Wikipedia, the free encyclopedia The rest of your statements are meaningless and demonstrate a complete lack of the knowledge of the subject, which is of course common amongst those who parrot statements rather than seek to understand. The second law of thermodynamics relates to closed systems. Living things are open systems. The argument upon which this entire thread is based is entirely ludicrous. Quote
