Figure 19. Histogram for the tree length distribution of all (nearly 654 × 106) possible trees using 12 terminal taxa and Dipterus as outgroup. The strict consensus tree of the 12 taxa is shown in the frame. The shortest tree length is 27 steps and the mean length of all trees is 44.95 steps (SD = 2.84). The skewness statistic, g1, is −0.745, indicating a strong phylogenetic signal of the data.
