Figure 4

Estimated age of three nodes selected to monitor the effect of alternative methods and parameters. Plot of the estimated ages and confidence intervals for three selected nodes recovered under alternative inference methods and partition schemes. Open circles correspond to mean estimated ages obtained from 100 bootstrapped branch lengths obtained with r8s or from the posterior distribution in BEAST; closed circles correspond to estimated ages obtained with r8s. Error bars represent the maximum and minimum values obtained from 100 bootstrapped branch lengths with r8s or the upper and lower bound of the 95% highest posterior density interval obtained with BEAST. Partition schemes as defined in text. i = models include invariants, otherwise they do not; cal = analyses run removing the opening of the Gibraltar strait as fixed calibration point; nprs = run under nprs clock model, otherwise run under penalized likelihood.
