Question

Quizplus · Accepted Answer

Human ancestors developed bipedalism to more effectively hunt and gather food in grasslands. Walking on two legs allowed them to cover greater distances and carry food back to their groups. While climbing trees and picking fruit may have been secondary benefits of bipedalism, they were not the primary reason for its evolution. Running across hot ash beds and riding elephants were also not factors in the development of bipedalism.
