Analyses were performed on each clade for which the hypothesis of homogeneous slopes was rejected (p-HOST). For positive values of D, p-D is the proportion of permuted values of D that were greater than or equal to the empirical value. For negative values of D, p-D is the proportion of permuted values of D that were less than or equal to the empirical value. Asterisks indicate the significance of p values at different levels (*: p ≤ 0.05; **: p ≤ 0.01; ***: p ≤ 0.001)
