Insectivores have forward vision, with eyes facing front rather than on side, allowing stereoscopic vision and space for larger frontal lobes.
hand
Insectivores have grasping hands, with opposing thumb across from fingers, for more eye-hand coordination and precise hand and arm movements.
evolution
Primitive insectivores evolved from placental mammals. Primates evolved from primitive insectivores.
types
Insectivores include mole, hedgehog, and shrew.
