Explanation:
Detailed explanation-1: -What makes human hands unique? The human opposable thumb is longer, compared to finger length, than any other primate thumb. This long thumb and its ability to easily touch the other fingers allow humans to firmly grasp and manipulate objects of many different shapes.
Detailed explanation-2: -Humans can move their thumb farther across their hand than any other primate. Having opposable thumbs helps in grasping things more easily, picking up small objects, and eating with one hand.
Detailed explanation-3: -The carpo-metacarpal joint allows the range of thumb movement necessary for both grips (Marzke, 1983).
