When Paul Kammerer committed suicide in 1926, it was taken by most of his fellow biologists as a tacit admission of guilt that he had faked his experiments purporting to show the inheritance of acquired characteristics. Arthur Koestler joins NOVA in an in-depth examination of Kammerer's infamous experiment.
