While there are various theories about the reasons for the transition to bipedality, there is no strong evidence to suggest that it was solely driven by the need to forage in a particular environment. It is likely that a combination of factors such as climate change, predation pressure, and adaptations for tool use played a role in the evolution of bipedality.
