Cranial studies involve the examination of skulls to understand various aspects of biology, anthropology, and archaeology. Researchers analyze the shape, size, and features of skulls to gather information about species evolution, health, and behavior. This field can provide insights into human history and the development of different cultures. These studies often utilize techniques such as CT scans and 3D modeling to create detailed images of cranial structures. By comparing skulls from different time periods or regions, scientists can track changes in human anatomy and assess the impact of environmental factors on cranial development.
