Phylogenetic evolutionary rate (σ2) of shape evolution among ecomorphs for the left (circle) and right (square) valves, with their 95% CIs. Abscissa values are ×10−7. Dashed and dotted lines represent the overall evolutionary rate for the left and right valves respectively. Pairwise comparisons between ecomorphs by valve are presented in Table 1. Confidence intervals were calculated via bootstrapping specimens in species-means estimations
