Final answer:
The statement that a woman's skull is usually bumpy compared to a man's skull is false. Human skulls have sutures which can feel like bumps, but there is no gender-based pattern in their bumpiness. Sexual dimorphism exists in aspects like pelvis shape but not in the bumpiness of skulls.
Step-by-step explanation:
The statement that a woman's skull is usually bumpy compared to a man's skull is false. Both male and female skulls have areas where sutures join the bones of the cranium, and these can be felt as ridges or bumps. However, there is no consistent pattern that would suggest female skulls are generally bumpier than male skulls.
Human skulls, whether male or female, consist of 22 bones that provide a framework for the head. These bones include eight cranium bones and 14 facial bones. Sutures such as the sagittal, coronal, lambdoid, and squamous sutures join these bones with dense, fibrous connective tissue, accounting for the sometimes palpable 'bumps' on the skull.
Sexual dimorphism in the human skeleton does exist, manifesting in differences such as the shape of the pelvis, but the bumpy nature of skulls is not a sexually dimorphic trait. While discussing hominid skulls such as Neanderthals or Australopithecus, note that their skulls had distinctive shapes and sizes compared to modern human skulls, but this is separate from the differences between contemporary male and female human skulls.
