Final answer:
The opposable thumb is advantageous to humans as it allows for precise and coordinated movements. It enables us to grasp objects with precision and provides the ability to create and use complex tools.
Step-by-step explanation:
The opposable thumb is an advantageous adaptation for humans as it allows for precise and coordinated movements of the hand. This is because the thumb can touch and move across each of the other fingers, enabling humans to grasp objects with precision and strength.
For example, when picking up a pen or using tools, the thumb can oppose the other fingers, providing a stable and secure grip. This ability greatly enhances our dexterity and fine motor skills, enabling us to perform intricate tasks such as playing musical instruments or typing on a keyboard.
Additionally, the opposable thumb gives humans the ability to create and use complex tools. By manipulating objects and tools with their thumbs, humans are able to perform tasks more efficiently, which has contributed to our survival and technological advancements.
