Figure 2
Scatter plots and regression lines displaying the number of nonsynonymous mutations as a proportion of the total number of mutations (i.e. dN/(dN + dS)) as a function of time (i.e. branch length/node age (Ma)). The blue dots represent the proportion of nonsynonymous mutations for taxa with the ancestral state (R2 = 0.52), while the red dots represent the taxa that illustrate life form shifts (i.e. the alternative state) (R2 = 0.82). The shaded regions represent the 95% confidence intervals of the regression lines.
