What is the advantage of walking upright? __

Walking upright, also known as bipedalism, has several advantages for humans. Firstly, it allows for greater energy efficiency during locomotion, as it requires less energy to move the body's center of gravity vertically rather than horizontally. This is because the body's weight is distributed more evenly between the two legs, reducing the strain on each individual leg. Secondly, walking upright frees up the hands for other tasks, such as carrying objects or using tools, which is particularly useful for tasks such as hunting or gathering. Finally, walking upright also allows for greater endurance during physical activities, as it allows for a more efficient use of oxygen and reduces fatigue. Overall, walking upright has played a crucial role in the evolution and success of the human species.
