Postural Feeding Hypothesis – The idea that bipedalism initially evolved for reaching and collecting food in trees.

Provisioning Hypothesis – A theory that bipedalism helped males gather and provide food for their mates and offspring.

Carrying Hypothesis – The theory that bipedalism evolved to allow early humans to carry tools, food, or infants.
