The paper analyzes in detail the Meselson-Stahl experiment, identifying two novel difficulties for the crucial experiment account, namely the fragility of the experimental results and the fact that the hypotheses under scrutiny were not mutually exclusive. The crucial experiment account is rejected in favor of an experimental-mechanistic account of the historical significance of the experiment emphasising that the experiment generated data about the biochemistry of DNA replication independently of the testing of the semiconservative, conservative and dispersive hypotheses.
