Human skull that has been disarticulated and reassembled with all the fixed parts at a certain distance from each other, maintaining their relative position. This allows us to see the different bones in the skull: four symmetrical mid bones (occipital, sphenoid, ethmoid and frontal), and two paired, lateral bones (the parietal and temporal bones). We can also see the three types of teeth and both jaws.
Used for the study of human anatomy. Craniometrics became very important in the development of two fundamental disciplines: Comparative Anatomy and Anthropology. The study and measurement of the bones in the skull and their angles was a central theme of the works of some of the most important scientists of the 19th century, such as Geoffroy Saint-Hilaire and Cuvier. The measurements for the human species as compared with those for other groups of mammals, and the comparisons made between the different human ethnic groups were key facts in the debate on the theory of evolution presented by Darwin, especially when it came to possible family relationships between humans and apes.
