Evolution

· Entropy refers to the dissipation of heat by which warm things grow colder. But those are inanimate things. Life preserves and increases energy. Putting on a coat in winter effectively defeats entropy, and so have all living forms for at least four billion years.

· The universe may die a “heat death” as it approaches absolute zero, but in the meantime, complex forms keep arising and surviving. The force that creates them is evolution.

· Unique among the living things yet discovered, Homo sapiens can consciously choose to evolve.
