Predictions of dp1 area (y-axis) based on the inhibitory cascade (orange circles) in living and fossil hyracoids with distinct deciduous (green) and permanent (blue) generations at the first premolar locus. Procacap = Procavia capensis, Saghabow = Saghatherium bowni, Thyrolit = Thyrohyrax litholagus, Thyromey = Thyrohyrax meyeri.
