If the naturalists and Darwinists were right about the evolution of humankind, we would expect both the quantity and quality of human artwork to increase gradually over time. New research, however, shows that the opposite is the case. Anthropologists have discovered what they call the “big bang” of artistic expression. Previous to about 40,000 years ago, art appears to have been both rare and “rough,” or crude.10 Such “art” (if it can really be called that) reflects the expressive ability we see in some advanced mammalian and avian species. After that date, art becomes suddenly ubiquitous and intricate, art that only humans—spiritual creatures—can produce.
