  1. The upper-right triangle shows the functional divergence (θ) values for all pairwise comparisons, data is presented as value ± standard error, the lower-left triangle shows the functional distance between two groups, the diagonal shows the functional branch length (b F ) values of each group, arbitrarily constraining b F (PBP) = 0.
