Monkey Trial (PBS, check local listings): "All the ills from which America suffers can be traced to the teaching of evolution," said William Jennings Bryan, a man who had fought for the common people throughout his career and saw the damage that the so-called "social Darwinism" had wrought on the national economy. He fought for women's suffrage, for farmers, for the underdog. For him, politics and religion were intertwined. But as the prosecutor of John Scopes, the teacher who taught evolution, Bryan is figured as the bad guy in the drama of the famous Scopes Monkey Trial. Clarence Darrow, the defense attorney, had fought on the same side as Bryan on many issues before religion separated them. But the actual Scopes trial, this documentary says, was all a put-up job - a conspiracy between the popular teacher and the local business community, who wanted publicity for their town and the business boom that would follow.
