How is the digestive system of a human and an ape related?

The digestive systems of humans and apes share significant similarities due to their common evolutionary ancestry. Both possess a similar structure, including a mouth, esophagus, stomach, and intestines, which are adapted for processing a primarily plant-based diet. However, humans have evolved a shorter digestive tract and specialized adaptations for a more varied diet, including cooking and processing food, which contrasts with the more robust digestive systems of apes that are suited for raw vegetation. Overall, these similarities and differences reflect adaptations to their respective diets and lifestyles.
