The method used to plot the divergence between sister species as they evolve farther and farther from their common ancestor is termed phylogenetically independent contrasts (PICs). PICs are a statistical tool that allow researchers to compare trait values between different branches of a phylogenetic tree while accounting for the shared evolutionary history of those branches. This method helps to control for the effects of phylogenetic relatedness on trait evolution, which can lead to spurious correlations and misleading results if not properly accounted for.
