Lambert & Whitham (2001) posit that the cheek pouches is an anatomical solution to maximizing energetic input while mitigating competition over limited food resources. Smith et al. (2008) posit that cheek pouches use could also reflect the differences in the distribution of food resources (such as leaf feeding sites).
What are cheek pouch monkeys?

Baby monkeys live with their mothers for one year to 18 months. Similar to humans, young monkeys are forced to live independently and discover their destiny.
Can humans Brachiate?
Although great apes do not normally brachiate (with the exception of orangutans), human anatomy suggests that brachiation may be an exaptation to bipedalism, and healthy modern humans are still capable of brachiating. Some children’s parks include monkey bars which children play on by brachiating.
Are chipmunks good for anything?
Though they do climb trees in search of food, generally they forage on the ground for seeds, insects and other small edibles, including special fungi that live around tree roots and that are critical to tree survival. Chipmunks help to spread fungi within a forest, just as they help spread seeds.
