When Charles Darwin published On the Origin of Species in 1859, he exposed the world to a momentous discovery . For the first time in history, human beings were seen not as creatures of divine origin, but instead, as a product of nature, an animal like every other on the planet. Imagine yourself back in that amazing year. The day before Darwin’s book was published, you wake up thinking yourself the image of God; the next morning you realize you have the face of a monkey. Not everybody immediately embraced this rude demotion from god to goat.
