Abstract
Although two decades have passed since the first biogeochemical studies of early hominin diet were published, the field has only picked up steam in the last few years. There have been major increases in available hominin carbon isotope data which allow exploration of temporal, taxonomic, and biogeographic differences in hominin diet, as well as further investigation of the relationship between diet and masticatory morphology. There have been fewer recent advances in hominin trace element studies (Sr/Ca, Ba/Ca), although evidence of intraindividual dietary variation, including a weaning signal, are likely to spur future research.
