Question

Think about your hand and thumb for a minute. Think about all the things you can do with your thumb and hand, all the things you can grab and pick up. Do you have an evolutionary advantage because you have an opposable thumb? Explain your answer.

Answer 1

The opposable thumb and movable hands in humans are an evolutionary advantage as they allow them to grasp the resources and objects in nature and help in survival.

What is an opposable thumb?

An opposable thumb is the evolutionary adaptation of the primates (humans) that allows the thumb to be placed opposite the fingers in the hand to grasp, handle and lift objects.

It is an evolutionary advantage as it allowed the humans to grasp the objects and resources present in the environment and allowed them to eat and write, unlike the other animals of the primate group.

Therefore, an opposable thumb is an evolutionary advantage.
