Charles Darwin’s theory of evolution challenged traditional religious explanations of human origins.
Some religious people, seeing divine intent in evolutionary change, embraced Darwin’s theory. Others saw it as a threat.

Only later was it noted that the textbook at the heart of the trial encouraged eugenics—a method of social engineering that valued certain bodies over others.
