Humans walk upright using two legs. This is called locomotion.?

Locomotion refers to the movement of an organism from one place to another, and in humans, this is primarily achieved through bipedalism, or walking on two legs. This upright posture allows for greater mobility and the use of hands for tasks while moving. The evolution of bipedal locomotion has also contributed to changes in human anatomy, including the structure of the pelvis and spine. Overall, bipedalism is a key characteristic that distinguishes humans from many other species.
