Results from BEAST dating analyses based upon different combinations of calibrations.

<p>The first line presents results based on both calibration points of 52 and 14 million years, while the second and third rows represent results under each individual calibration. The mean and 95% highest posterior densities are given for each node (in millions of years), and we report the per lineage mean rate of evolution per million years for each gene in the last two columns.</p>
