This morning you rolled out of bed and did one of the most confounding things known to paleoanthropology: you stood up.
Another theory is that our pre-human ancestors took to the water, becoming aquatic apes. You don’t need hair in water and we have more fat under our skin than all other land mammals. We can also swim better than any other primate and our nostrils are built so we don’t take water when we dive. But no, the fossil record shows huge crocs in the Rift Valley lakes where we are thought to have begun.
All other primates eat what they find, but to bring food home required the ability to carry it and walking on two legs made that possible.

To do that they needed to become bipedal.
