THREE-DIMENSIONAL THINKING
Primates such as humans and chimpanzees have opposable thumbs,
which means that the thumb can move around to touch the other
fingers on that hand. What type of adaptation is this? Explain why
opposable thumbs are a beneficial adaptation. Record your response
in your Science Notebook.

Answer 1

Opposable thumbs are a beneficial adaptation for primates because they enable dexterity and flexibility in tasks such as tool use and writing.

Step-by-step explanation:

The opposable thumb is an adaptation called prehensility, which allows primates to grasp and manipulate objects with precision. This adaptation is beneficial for primates because it enables them to perform various tasks such as tool use, feeding, grooming, and writing.

For example, humans can use their opposable thumbs to hold a pen and write, while chimpanzees can use their thumbs to grasp and use sticks as tools.

Overall, opposable thumbs provide primates with increased dexterity and flexibility in their daily activities.
