Fig. 3From: Revisiting phylogenetic signal; strong or negligible impacts of polytomies and branch length information?Frequency histograms showing differences in branch length variability (standard deviation) between “true” chronograms and pseudo-chronograms calibrated with BLADJ (fixing 5% of the nodes). Note that overall, pseudo-chronograms show lower branch length variability (i.e. branch lengths are more homogeneous) than perfectly dated “true” chronogramsBack to article page
