Supporters and critics in court battle over "Intelligent Design"

In the United States, an important cultural battle is being waged in a Pennsylvania courtroom. The supporters and critics of evolution are going head to head over whether "Intelligent Design" should be taught in schools. Intelligent Design is a theory that evolution can't satisfactorily explain the diversity of life, and that some sort of designer must have been involved. The battle is happening eight decades after the famous Scopes Monkey Trial, reports North America Correspondent Mark Simkin.
