Is craniofacial asymmetry and adaptation for masticatory function an evolutionary process?

Abstract

MANY workers have investigated asymmetry of primate skulls. Woo1 carried out direct chordal and arcual measurement on a large number of human skulls from the 26th to the 30th Egyptian dynasties. He found the bones of the cranium exhibited an asymmetry with the right side being larger, reflecting the development of the right hemisphere of the brain. The contralateral side of the facial complex exhibited an asymmetry with the left zygoma and left maxilla being larger. The lower third of the face was not investigated. © 1974 Nature Publishing Group.
