MORPHOLOGICAL COMPARISON OF MANDIBLE IN HUMANS AND GREAT APES: A COMPARATIVE STUDY IN BOTH SEXES
Abstract
This study aimed to compare the morphological changes of the mandible in humans and great apes and analyze the differences between sexes. CT scans of the mandibles of 20 human and 20 great ape specimens, both male and female, were analyzed using 3D reconstruction software. The results showed significant differences in mandibular morphology between humans and great apes, with humans having a more vertically oriented mandible with a more prominent chin and great apes having a flatter, horizontally oriented mandible. Males in both humans and great apes had larger mandibles than females, with a greater degree of sexual dimorphism in great apes. These findings may have implications for understanding the evolution of the craniofacial complex and the factors that contribute to sexual dimorphism in mandibular morphology.
