Okay, Consider the Earth as an open system and our universe as the closed system. After all, we're not out to disprove the Second Law of Thermodynamics, and any attempt to do so belongs on a different thread in the physics forum: it's not a hypothesis, it's not a theory, it's a "Law."
The direction of evolution to create diversity of life on Earth, using up energy in the process, energy through life's metabolisms and extinctions, some of that energy of which is lost forever and can never be reused or recovered, is a perfect example that shows the Second Law of Thermodynamics in action. These transformations of life forms resulting in a vast increase and diversity of species leads to disorder and increased entropy. Evolution results in an increase in disorder by the diversity of life that it has created. By definition, this is in increase in entropy: an increase in the number of possible internal configurations available in the system. The more life forms evolution creates (and as I stated on a different thread, the number of species present on Earth today represent only about 0.1% of all species that ever existed on Earth: the other 99.9% went extinct), the more diverse the life forms get, the more disorder there is in the system, and this is an increase in entropy, or stated in another way: an increase in the number of configurations in the universe.
