This study examines the morphology of the hyoid in three closely related species, Homo sapiens, Pan troglodytes and Gorilla gorilla. Differences and similarities between the hyoids of these species are characterised, and used to interpret the morphology and affinities of the Dikika A. afarensis, Kebara 2 Neanderthal, and other fossil hominin hyoid bones.
Humans and African apes are found to have distinct hyoid morphologies. In humans the maximum width across the distal tips of the articulated greater horns is usually slightly greater than the maximum length (distal greater horn tip to most anterior point of the hyoid body …
