Tool making is not a scenario for the evolution of bipedalism. The other options are all theories that suggest why bipedalism evolved in early hominids. Energy efficiency suggests that walking on two legs was more efficient than quadrupedalism, allowing for longer periods of activity and travel. Ecology suggests that environmental changes, such as forests being replaced by savannas, may have forced early hominids to adapt bipedalism to navigate their new environment. Sexual selection suggests that bipedalism was selected for because it made early hominids more attractive mates.
