| In addition, AhR signaling affects molecular clock genes to influence glucose metabolism. |
| Although a molecular clock is rejected, divergence times may still be estimated by allowing the rates of evolution to evolve along lineages. |
| We introduce a parametric model that relaxes the molecular clock by allowing rates to vary across lineages according to a compound Poisson process. |
| The wide range of dates is due to the different records used to calibrate the molecular clock. |
| Divergence times among clades in the ochrocephala complex were estimated using two different molecular clock calibrations. |
| Using the molecular clock method, it was possible to determine the age of the major branches of the orchid family. |
