Figure 4 : A cubic function describes ear closure across species.

From: Comparative analysis of ear-hole closure identifies epimorphic regeneration as a discrete trait in mammals

Figure 4

Ear-hole area modelled over time following a 4-mm ear-hole punch for each species (box and whiskers). The estimated cubic function is overlaid from D5–D30, and the data are graphed separately for each sex (male=solid line and female=dashed line). For comparison, all cubic functions are overlaid in bottom right panel.
