Students have asked these similar questions
Do you think that the digestive system of humans is similar to those of other animals? Where might you see the most prominent differences especially between humans and animals with different diets?
Enzymes are proteins, and therefore are structurally linked to DNA sequences. How could natural selection alter the metabolism of an organism?
Question:
1. Explain how the processes of Evolution have shaped the development of features especially adapted to their function within the Digestive System. Describe one example from each part of the digestive system.
