With the monkeys large nose, big stomach with compartments, and strong large hind legs. The monkey will survive with help of humans but still need lots of adaptations to live on there own. Most importantly, the proboscis monkey didn't use to have the nose they have today. They use to look like orangutans. Now they are covered in orange fur, have a nose like a banana, and four stomachs just for leaves. The orange fur came from its older self. Also, the nose actually is a defense mechanism to protect a territory and/or there lives. Finally, the four stomachs play out to digest the leaves completely.
