Skull Index

The Skull Index is a measurement used by scientists to compare the shape of skulls across different species or populations. It’s calculated by dividing the width of the skull at its widest point by its length from front to back. A higher Skull Index indicates a relatively wider skull compared to its length, while a lower value suggests a longer, narrower skull. This measurement helps researchers understand evolutionary relationships, adaptations, and variations in skull shape among species or groups without requiring invasive procedures.
