The feature that distinguishes the human skeleton from most other animals, along with an erect structure that enables us to walk on two legs, is opposable thumbs. This trait allows for a greater range of dexterity and the ability to grasp and manipulate objects effectively, which is a significant advantage for tool use and various tasks.
