This includes the modern conception of evolution, which has radically altered humanity’s image of itself. Organisms can be thought of as imperfect self-replicators which produce closely-related species, allowing for selection and evolution. bioshock franchiseThe second law of thermodynamics states that the disorder (entropy) of a physical or chemical system and its surroundings (a closed system) must increase with time. Systems left to themselves become increasingly random, and orderly energy of a system like uniform motion degrades eventually to the random motion of particles in a heat bath. bioshock game studio
