The hyoid bone is one of the few floating bones in the vertebrate skeleton. Its main function in all animals is to depress the tongue to aid in deglution. While variations in vertebrate hyoids do exist, their similarities are more notable. In order to evaluate the significance of the human hyoid, a cross-temporal examination of human hyoids, an analysis of metric variance and a cross-species comparison of hyoid morphology was conducted for this study. Human hyoid samples were obtained from hyoids taken at autopsy from a modern collection, and hyoids recovered from remains of 18th century Londoners disinterred from the crypt of Christ Church Spitalfields. The hyoid recovered with fossilized Neanderthal remains from Kebara Cave in Israel (dated at 60000BP) was also compared to the pooled sample. The results indicate that human variation in the adult hyoid is minimal. Sexual dimorphism was found, but not with reliably predictive results above 70%. Likewise, reliably predictive results determining race from the human hyoid could not be found. Despite claims in the literature to the contrary, the Kebara hyoid fell well within the normal range of human variation. The hyoids of infants in the modern sample did, however, show significant variation between infants who died of SIDS versus infants who died of other causes. The SIDS infants had significantly smaller hyoid bodies, suggesting that this characteristic might lead to a diagnostic method that would identify at risk children before a SIDS event. The last consideration in this study was manual strangulation and its relationship to hyoid fracture. The hyoids of individuals who have not passed reproductive age for females are flexible, resisting external pressures but breaking easily from internal pressures. Consequently, presence or absence of hyoid fracture is not determinative of manual strangulation.
