  1. a mutation rate: one base substitution in the coding region per 5, 140 years [58].
  2. b mutation rate: one synonymous transition per 6, 764 year [76].
  3. c Calculated using as per calibrated mutation rate of Soares et al. [59].
  4. d 95% confidence interval: negative values are zeroed.
  5. * Excluding branches A2a and A2b.
  6. ** Only two sequences hence coalescent age not reliable.
