Asymmetry in East African skulls.

Skulls from 297 East Africans were examined in relation to their symmetry; 98% were found to be asymmetrical. The most common types of asymmetry were right fronto-petalia, left parieto-petalia, and left occipito-petalia (21.2%). No significant differences were found among the East African populations. Sixteen per cent of the skulls had wormian bones, all of which were found in asymmetrical skulls. The problem of asymmetry of skulls is discussed and the literature on the subject reviewed.
