  1. Significance of rate differences determined by comparing fully constrained tree likelihood to tree with specified node unconstrained. *p < 0.01, **p < 0.001, ***p < 0.0001. All significant results remain significant after sequential Bonferroni tests as described in Rice, W.R. 1989. Evolution.43: 223–225.
