Humans are bipedal, terrestrial omnivores. As a species, we are adapted to quite a range of habitats, from deserts to mountains and from rain forests to tundra. Ultimately, however, we are descended from early hominids who evolved in African plains, and our body systems tend to reflect this. Your job is to determine how humans might be adapted to specific environments if they had evolved to eat a herbivorous diet (grasses or leaves).
Write a brief description of the digestive system, and why it would look the way it does. Consider the following:
Humans are generally omnivorous can eat both plants and meats. If human is converted to eat only the plant materials such as grasses and leaves may lead to evolve as a herbivorous animal. So many anatomical changes will occur in the body based on the diet. They can prefer eat only leaves(Folivores), fruits (Frugivore) , seeds (Granivore) or all on the availability. But in general the following changes will occurs on anatomically
Mouth and Teeth
If human is not an omnivorous they could be in different in diet may not be related with their structural posture. For example Gorilla is a frugivore can eat fruits by its hands and we can also acquire food by plucking by hands likes what we now doing. But the enzymes and mechanisms will be changed gradually. But as we are omnivores a higher difference may not be seen if we change into frugivory or granivory.
