How many of you know what ENTROPY is? If not here is the definition Entropy-A measure of the disorder that exists in any system. How does this apply to there theory of evolution? Well you first have to look at the Second Law of Thermodynamics. What is this law? Well here it is The Second Law of Thermodynamics- The entropy of the universe MUST allways stay the same or increase. It can never decrease. How is this applicable to evolution? Well, if an advanced species(which is highly ordered) did evolve from a simple species(which is less ordered), then that organism would have, indeed, experienced a decrease in entropy. To make this consistent with the seconed law of thermodyanmics, then the organisms surroundings would have had to become more disordered so that the decrease in entropy of the organism could be offset. This is the only way evolution can be consistent with the seconed law of thermodyanmics.
Thus suppose a single-celled creature where to evolve into a cell that would cooperate with other cells. Evolutionists will tell you that this can happen if the cell's DNA were to undergo a mutation that would make the DNA a little more advanced. The problem is that the very instant that DNA mutated and became more ordered, there would have to be a corisponding increase in entropyin the organisms surroundings so the the total entropy of the universe would still increase or stay the same. No scientist can come up with a single idea of as to how that can happen. As far as anyone can tell, mutating DNA does not significantly increase the entropy of the surroundings.
So you see that the seconed law of thermodynamics doesnt really disprove evolution, but it does put some pretty strong conditions on it. The seconed saws that if evolution where to occure, then each step of that evolution must be accopanied by an immediate increase in the entropy of the surroundings. If anyone ever comes up with a mechanism by which this might happen, evolution could at least be made consistent with the seconed law of thermodynamics. Currently no one can come up with even a vague notion as how to this might happen. As a result, the current theories of evolutionare not consisten with the seconed law. this does not meen that the seconed law disproves these theories, however. It just meen that no one has come up with a proper mechanism for which this can happen. my personal opinion is that there is no such one.
