Procedure for calculating species’ branch lengths. (a) Chronogram from Bayesian analysis. (b) Estimating lineage branch length: species lacking molecular data are inserted sequentially at the half length of the longest branches (dashed, orange branches). (c) Total branch length of the clade is standardized and species polytomized at the stem, which corresponds to the original age of lineage minus the species standardized branch length.
