Gus > Entropy is the only quantity in the physical sciences that "picks" a particular direction for time, sometimes called an arrow of time. As we go "forward" in time, the Second Law of Thermodynamics tells us that the entropy of an isolated system can only increase or remain the same; it cannot decrease.

Evolution is, in fact, the opposite to entropy which suggests that with time the disorder in a system will increase. Evolution demands more specialization and less disorder. It cannot be driven by existing physical principles as we understand them.

Moreover, evolution actually necessitates that the system transforms to an entirely different state as brand new creatures, albeit with similarities to existing ones, appear. There is, thus, a discontinuity between one system and another and it is this that is hard to explain.
