From: The evolution of anthropoid molar proportions

Fig. 1

Anthropoid lower molar proportions (n=100). Points are species mean molar proportions. Convex hulls denote the range of species values for each higher ranked taxon. Solid line and surrounding polygon ribbon are the estimated mean and 95 % highest density interval for interspecific slope and intercept. Dashed line indicates DIC model’s predicted relationship between molar proportion ratios: M 3/M 1=2(M 2/M 1)−1. White regions are locations in molar proportion morphospace consistent with the DIC model: a high a/i region where M 1<M 2<M 3 and a low a/i region where M 1>M 2>M 3
