Question

The modern man differs from the apes in

• A. The absence of tail
• B. Sparse body hair
• C. Broaden chest due to the flattening of sternum
• D. Arms shorter than legs

Answer 1

The correct option is D Arms shorter than legs

Evolution causes the change in the heritable character from one generation to the other. The maximum use of a particular organ in a period of evolution causes its development. The modern man differs from the apes in arms shorter than legs. In apes, the arms help in the locomotion called trachiation, a type of suspension and swinging of the body. The arms of the apes developed more in modern man in course of evolution to adjust in the changing environment.

So, the correct answer is option D.
