Figure 9. Squared-change parsimony traced phylogenies for abdominal aspect ratio and caudal aspect ratio. For each species, the mean of abdominal and caudal aspect ratio was calculated for this analysis. The interrelationships of the seven clades examined are based on Lauder & Liem (1983), and references for the intrarelationships are given in the legend to Fig. 3. Both traces are based on a squared-change parsimony algorithm in MacClade, version 4.06 (Maddison, 1991). Lighter coloured branches (white, yellow) are lower values of aspect ratio and darker branches (purple, black) are higher values of aspect ratio.
