Answer :
Final answer:
The skeletal adaptations to bipedality include a straight vertebral column and a transverse arch in the foot.
Explanation:
Skeletal adaptation to bipedality:
One skeletal adaptation to bipedality is the straight vertebral column. The curves of the spine help support an upright posture and distribute weight effectively.
Pelvic blades that curve in an anterior/posterior direction are not a skeletal adaptation to bipedality. The pelvis shape is more associated with how humans give birth to large-brained infants.
Obody mass out in front of the chest is also not a skeletal adaptation to bipedality. The position of the center of mass and body weight is influenced by factors such as muscle development and overall body composition.
Another skeletal adaptation related to bipedality is the transverse arch in the foot. This arch helps absorb shock and maintain balance while walking or running.
