This female chimpanzee pelvis and femur set is from an individual who had given birth to at least three live offspring.
She was recorded as weighing 120 pounds at the age of approximately 25 years.
The chimpanzee pelvis and femur are built to navigate across ground in a quadrupedal knuckle-walking movement.
While able to stand upright and walk for a short distance, the chimp sways from side to side in an inefficient bipedal gait due to the shape of the pelvis and positioning of the attached muscles.
