The New Deal, Products of Evolution

Culture, like nature, evolves. Old ideas are made better, and become new ideas. Splits are made between schools of thought, and each side develops into something distinct from the other, even though both are the recognizable progeny of the previous generations. The growth of music over the last hundred years is perhaps one of the most notable examples of cultural evolution in action, and all the more remarkable since the existence of music is, arguably, unnecessary for the continuance of the human species.
