Secular Changes in Cranial Morphology and Pattern of Sexual Dimorphism in Modern Japanese: A Geometric Morphometric Analysis Using Post‐Mortem Computed Tomography Data

Key Points

• The aim is to analyze changes in cranial structure over the last century and understand patterns of sexual dimorphism in modern Japanese individuals.
• Conducted a geometric morphometric analysis using post-mortem computed tomography data
• Examined cranial morphology across a century
• Analyzed sexual dimorphism patterns in cranial features
• Significant changes in cranial morphology observed over the last hundred years
• Identified clear patterns of sexual dimorphism in cranial structure
• Findings may enhance forensic accuracy in determining sex from skeletal remains
