Question

Quizplus · Accepted Answer

Human skeletons are characterized by an erect posture and a large skull, which houses our relatively large brain. While we do use two limbs for movement, that is not a defining feature of the skeleton, unlike the erect posture and large skull. Therefore, B and D are both incorrect. A small skull would not be expected for a human skeleton, as our brain size is one of our unique features, so A is also incorrect.
