Fig. 2

Comparison between the branching structure of a simulated “true” chronogram (a) and that of the same tree topology with branch lengths reassigned after using BLADJ (pseudo-chronogram) (b). The highlighted nodes in the pseudo-chronogram were fixed, and unknown nodes were placed evenly between fixed nodes. Note the marked difference in branch length variability between both branching structures
