The third law of thermodynamics states that
any system left on its own will advance to a state that is worse and more confused than the one it started at.

I am probably not the best person to explain the evolution of the Earth. But from what I know it is a rather complicated phenomenon. Partly due to plate tectonics--the movement of the continental plates, impacts of meteorites, climatic changes such as the ice ages and perhaps even by the bombardment of cosmic rays on the Earth. Also the natural selection of life forms--survival of the fittest.

to me the evolution of the earth seems to survival of the smartest rather than survival of the fittest. The smart survive, the stupid don't. Yet....somehow, the "stupid" genes keeps getting passed down. It's a rather curious phenomenon.

3.9 Ga, earth melted due to radioactive elements, U, Th and K.
3.7 Ga. (?) earth solidified.
3.3 Ga, (?) Completion of he differentation of the core/mantle
3.7 Ga to present, ongoing differentation of the mantle/crust boundary.

Earth is a dynamic system. It evolves because of its atmosphere, plate tectonics, vulcanism, etc.,.
