What is the theme in Summer for the Gods: The Scopes Trial and America's Continuing Debate Over Science and Religion by Edward Larson?

One of the central tensions in the events surrounding the trial is that of evolution vs. creationism. Larson shows that during the nineteenth century, science and evolution appear to have coexisted and mingled. Scientists and theologians often saw evolutionary theories in harmony with biblical accounts of creation. This began to change as new fossil discoveries came to light and as more and more students began encountering evolution theories in secondary schools. Theories of evolution came to be seen as contradictory to those of creationism and the biblical account.
