Their distinctive locomotion is the brachiation with their long arms and they can jump up to 50 ft for this feature. But they can also leap (up to 26 ft) and walk bipedally with arms raised for balance. They have long, curved and slender digits on hands and feet with shorter thumb which help them to grab onto branches easily when they brachiate. Also their shoulder muscle is developed due to their locomotion. Their fur is generally gray, black or brown, often with white marks on face, feet and hands. Orangutans are the largest Asian ape. They are slow and careful climbers that use all four limbs to grasp and support. They sometimes move quadrupedally on the ground though they are arboreal (Jurmain, et al, 2011).

The hallux is aligned with other toes which is adapted to bipedal walking patterns. They have flexible limbs and grasping hands that indicate their primate, arboreal past. Humans in current time has lost noticeable amount of hair which covered almost the entire body before. When compared with other species, humans have a highly developed brain capable of abstract reasoning, language, and introspection. This mental capability, combined with an erect body carriage that frees their upper limbs for manipulating objects, has allowed humans to make a far greater use of tools than any other species (Fleagle, 1999).
