Since we know that entropy = information, one of the testable and confirmable facts of the second law is that information and complexity are guaranteed to increase with time, not decrease. Reminds me again about: Information = Entropy and Chance = Choice. I hope the author ( Granville Sewell) can catch up on the conversation a bit.
Here is what the author writes:
I hesitate to bring the second law back into this debate because of the controversy it always generates. But people sometimes say that the second law only requires that order should not increase (entropy should not decrease), it does not require that order must actually decrease, so there is nothing unnatural about species simply maintaining their complex structures and passing them on generation after generation without significant degradation. Yet common sense tells us that, when only natural forces are at work, complex things must degrade, and slowly only if everything is almost “frozen in time” (nothing is changing), or else they are already degraded to nearly simplest form.
Obviously, neither of these conditions holds for the case of animal reproduction. Common sense is actually confirmed by the equations of entropy change when we consider the application of the second law to diffusion of a substance X. Notice that since usually J = -D*gradient(C), equation A7 of my Physics Essays article (equation A4 for the case where X-entropy is just thermal entropy) says that if “X-order” is not imported from outside (the boundary integral term is zero), the only way X-order can not decrease rapidly is when either things are almost frozen in time (the diffusion coefficient D is small), or the X-order is already close to the minimum possible (gradient(C) is small).

I hope that Sewell can join us. Should be very interesting.
