Head and mandible shapes are highly integrated yet represent two distinct modules within and among worker sub-castes of the ant genus Pheidole

Ants use their mandibles for a wide variety of tasks related to substrate manipulation, brood transport, food processing, and colony defence. Due to constraints involved in colony upkeep, ants evolved a remarkable diversity of mandibular forms, often related to specific roles such as specialized hunting and seed milling. Considering these varied functional demands, we focused on understanding how the mandible and head shape vary within and between Pheidole sub-castes. Using x-ray microtomography and 3D geometric...
