Cranial morphology refers to the study of the shape and structure of the skull, which houses and protects the brain. It involves analyzing various features such as the size, form, and arrangement of bones in the skull. This field is important in understanding evolutionary biology, as variations in cranial morphology can indicate adaptations to different environments or lifestyles. Researchers often compare cranial morphology across different species, including humans, primates, and other mammals, to identify evolutionary trends. Techniques such as 3D imaging and geometric morphometrics are commonly used to quantify and visualize these differences, providing insights into functional aspects of the skull and its development over time.
