Final answer:
Bipedalism is a major component of being human and can be analyzed anatomically. Key adaptations include the angling of the femur, spinal curves, foot arch evolution, and big toe repositioning.
Step-by-step explanation:
Bipedalism is a major component of being human, and it can be analyzed from an anatomical perspective. One of the key anatomical changes that facilitate bipedalism is the angling of the femur (upper leg bone) inward at a valgus angle, which positions the knees and feet under the center of the pelvis. Other adaptations include spinal curves, the evolution of the foot arch, and the repositioning of the big toe. These changes help transmit weight during bipedal locomotion.
