The basal amniote ankle condition consisted of a simple mesotarsal joint. Based on the anatomy, predict which type of ankle movement this would allow.
a. Dorsoventral flexion (flexing up and down in the longitudinal plane of the limb)
b. Lateral movement (side-to-side movement perpendicular to the longitudinal plane of the limb)
c. Pronation and supination (rotation around the longitudinal plane of the limb)
d. All of the above
e. None of the above
