Question

Which of the following represents a major change in the transition from ape to man?

Options

• Loss of opposable thumbs

• Increased reliance on quadrupedal locomotion

• Increased brain size and complexity with bipedal locomotion

• Decrease in brain size and complexity

Answer 1

Major changes in the transition from ape to man included increased brain size and complexity, greater intelligence, increased cranial capacity, and bipedal locomotion. These changes, along with the development of an opposable thumb and erect posture, were fundamental to human evolution.
