Question

Which of the following is not characteristic of apes?

Options

• Movement on the trees by brachiation

• Wrists that bend backward

• Movement on the ground by knuckle-walking

• Highly mobile shoulder joints

Answer 1

Wrists that bend backward

Explanation:

Apes typically move on trees by brachiation, have highly mobile shoulder joints, and move on the ground by knuckle-walking. However, their wrists do not bend backward; backward bending wrists are not characteristic of apes. This flexibility in wrists is limited in apes and is not used for locomotion or other typical behaviors. Thus, option (b) is the correct answer as it is not characteristic of apes.
