An interesting article looks at understanding the nature of evolution through the lens of thermodynamics. See:
"As a biological ecosystem evolves by the process of natural selection, it disperses energy, increases entropy, and moves toward a stationary state with respect to its surroundings. Similarly, as energy flows in various physical phenomena, they too cause biological systems to move toward stationary states with respect to their surroundings, in accordance with the second law of thermodynamics. Whether an object is animate or inanimate, science does not seem to make a distinction. In both cases, energy flows toward a stationary state, or a state of equilibrium, in the absence of a high-energy external source. "
Note that such shifts in energy utilization may be beneficial for a period of time and then, as the ecosystem changes, less beneficial, where the term "beneficial" refers to persistence and perpetuation of the species.
This also helps to address the erroneous notion that systems only move in a direction of greater simplicity and cannot move in a direction of increased complexity. Clearly, that's just a brain dead notion.
Undoubtedly, there is some scripture somewhere written a few thousand years ago by a half-starved psychotic that might shed more light on the situation.
