Estimates of mutation rates and divergence dates from complete versus partial genomes. Imposing carnivore-based estimates of mutation rates and a log-normal distribution shows that the modal time to an observed mutation for the complete fisher mitochondrial genomes is 8,428 years (95% C.I. = 5,004 - 17,364), based on all 3,796 third codon positions in the mitochondrial genome (brown). This value is significantly lower than the modal time to an observed mutation for the 379 third codons of cytochrome b (pink; 84,411 years, 95% C.I. = 50,115-173,914).
