Once hominins became bipedal, they almost immediately lost their arboreal traits. Despite these advantages, bipedalism also has considerable disadvantages. Being bipedal allows humans to have a more comprehensive view of the surroundings, unlike the quadrupedal animals who have limited view. Other chimps acquired a different type of locomotion that made it easier to walk and run on the ground, as seen in humans. It is not uncommon to see animals standing or walking on 2 legs, but only a few animals practice bipedalism as their usual means of locomotion.
