In the final part of this documentary, Dawkins explains how the theory of evolution is probably the most controversial and questioned theory out there.
He speaks to people who oppose the theory of evolution and questions them on their beliefs while showing them the facts that have been found. He also speaks to the teacher of the science class in the first part and asks why the students had not adequately learned about the theory of evolution, and why they are telling to students that they can believe what they want when there is clear scientific proof that it is true. Dawkins also examines a bit of Darwin’s life and his beliefs before developing the theory. Each part of the series looks at a different inventions. The five inventions explored in this series are: the gun, the jet, the telephone, computers and the television.
