Which of the Following is an Advantage of Bipedalism in Hominins

Question

Which of the following is an advantage of bipedalism in hominins?
A) Standing on two feet makes it easier to climb trees.
B) Standing on four feet elevates the head, making it easier to see over obstacles and to see farther to allow earlier detection of predators.
C) Walking on two feet requires more muscle groups and more energy than walking on all fours.
D) The hands are free to carry food, tools, and weapons.

Accepted Answer

Bipedalism frees up the hands, allowing hominins to carry food, tools, and weapons, which would have been an advantage in early human societies as it would have increased their ability to gather and hunt for food, defend themselves and their territories, and engage in other complex social behaviors. A, B, and C are all disadvantages or incorrect statements about bipedalism.
