Reconstructing the diet of African hominid Australopithecus anamensis
See on - Pre-Modern Africa and Middle East

The diet of Australopithecus anamensis, a hominid that lived in the east of the African continent more than 4 million years ago, was very specialized and, according to a new study, it included foods typical of open environments (seeds, sedges,…

Traditionally, the reconstruction of the diet of Australopithecus anamensis was carried out by means of indirect evidence (specifically, studies of microstructure and enamel thickness, and the dental size and morphology). In this new study, the team of the UB analyzes the pattern of microstriation of the post-canine dentition, from microscopic traces that some structural components of plants (phytoliths) and other external elements (sand, dust, etc.) leave in the dental enamel during the chewing of food. It is, therefore, a direct analysis of the result of the interaction of the diet with the teeth.
