Question

During the course of evolution, which part of the brain has shown maximum increase in size.

• A. Midbrain
• B. Forebrain
• C. Hindbrain
• D. All of the above

Answer 1

The correct option is B Forebrain

During the course of vertebrate evolution, there have been few changes in the hindbrain. The truly major evolutionary change has been the steady increase in size and importance of the cerebrum, which is a part of forebrain, with a corresponding decrease in relative size and importance of the midbrain.

Thus, the correct answer is option B.
