  1. Node ID corresponds to those shown in Fig. 1. In MCMCtree and Phylobayes, age estimates are given for analyses under the independent rates model33 for both RNA and Proteins. In MCMCtree, two separate models of evolution were implemented for RNA and two for proteins. In Phylobayes the CAT-GTR model was implemented for RNA and proteins. Two separate analyses were performed setting the root with a maximum age at 2,700 Myr63 and at 3,000 Myr64, all analyses implemented a minimum age of 2,320 Myr2. Values in parenthesis correspond to posterior 95% confidence intervals associated with median age estimates.
