Human beings do not carry civilization in their genes. All that we do carry in our genes are certain capacities- the capacity to learn to walk upright, to use our brains, to speak, to relate to our fellow men, to construct and use tools, to explore the universe, and to express that exploration in religion, in art, in science, in philosophy.
