Repeated and Time-Correlated Morphological Convergence in Cave-Dwelling Harvestmen (Opiliones, Laniatores) from Montane Western North America
Figure 5
Based on three calibration points (arrows), with 95% confidence intervals for all estimated nodes. Confidence intervals for the root of the tree and the outgroup clade are given below the nodes. Posterior probabilities less than 95 are shown with red node bars. Troglomorphic populations/taxa indicated by special icons.
