Impact of accounting for dependent sites on the dating of the tree of life. Ultrametric trees resulting from an analysis with the penalized likelihood method (27) configured to accommodate for large rate variation ($\lambda =0$) of the majority rule consensus trees inferred by CoevRJ (left) and a purely independent sites model (GTR+$\mathrm{\Gamma }$, right). The root age is arbitrarily placed at 1.
