How do scientists calibrate a molecular clock? A)They determine the number of mutations accumulated in a gene of a species of known age. B)They compare the ticking of the molecular clock with that of the atomic clock. C)They use the clock that ticks at the appropriate rate for the divergence rate that they are trying to calculate. D)They compare the number of positive mutations that have occurred in a particular species with the number of negative mutations that have occurred.
