Final answer:
Colobines are medium to large monkeys that have higher cusps on their molar teeth and a sacculated stomach, which are adaptations for a leaf-based diet.
Step-by-step explanation:
Colobines are medium to large monkeys (4–20 kg) and differ from cercopithecines in having higher cusps on their molar teeth and in having a sacculated stomach (like cows), both adaptations for a diet of leaves.
This statement is true. Colobines, also known as leaf-eating monkeys, have specialized adaptations in their teeth and digestive system that allow them to efficiently consume and process a diet of leaves. These adaptations include higher cusps on their molar teeth and a sacculated stomach.
