Richard Dawkins sits down with The Science Network to talk through the argument of his book The Greatest Show on Earth, which sets out the evidence for evolution the way a prosecutor lays out a case, rather than trying to persuade in the abstract. He runs through the kinds of proof he considers hardest to dismiss: the fossil record, the shared genetic code across species, and the small observable changes in living populations that add up over deep time. The conversation format lets him respond directly to the objections raised by creationism and intelligent design, naming them and explaining why he thinks they fail against the evidence rather than against belief itself. There is no reenactment or location footage here, just Dawkins talking through his reasoning, which is also the point: the book itself was written as a direct answer to people who ask him for the evidence rather than the theory.
