As the African tropics changed to savanna, hominins moved onto the savanna while other apes remained in the forest. A major adaptation to the savanna was the evolution of bipedal locomotion. Which of the following is NOT a skeletal change associated with bipedal locomotion?

Question

Quizplus · Accepted Answer

The correct skeletal changes associated with bipedal locomotion include the alignment of the foramen magnum directly beneath the skull, a shortened and broadened pelvis, and an arched foot with the loss of an opposable toe. However, the femur in bipedal locomotion becomes longer and is angled inward (not outward) to accommodate pelvic changes, which helps in maintaining balance during walking.
