Figure 9.

The dependence of tree inconsistency on the split depth. The mean inconsistency value (IS) is shown for each split depth (1 to 46), which was determined by counting the splits in the trees from leaves to the center of the tree. (a) Schematic of the procedure used to determine the split depth. (b) IS plotted against split depth for all 6,901 trees of the forest of life. (c) IS plotted against split depth for the 102 NUTs. The vertical axis on the right in (b, c) shows the z-score, and the grey bars show the z-score values for the respective depths.
