Hominin dietary specialization is crucial to understanding the evolutionary
changes of craniofacial biomechanics and the interaction of food processing
methods' effects on teeth. However, the diet-related dental wear processes of the
earliest European hominins remain unknown because most of the academic attention
has focused on Neandertals. Non-occlusal dental microwear provides direct
evidence of the effect of chewed food particles on tooth enamel surfaces and
reflects dietary signals over time. Here, we report for the first time the direct
effect of dietary abrasiveness as evidenced by the buccal microwear patterns on
the teeth of the Sima del Elefante-TE9 and Gran Dolina-TD6 Atapuerca hominins
(1.2-0.8 million years ago - Myr) as compared with other Lower and Middle
Pleistocene populations. A unique buccal microwear pattern that is found in Homo
antecessor (0.96-0.8?Myr), a well-known cannibal species, indicates dietary
practices that are consistent with the consumption of hard and brittle foods. Our
findings confirm that the oldest European inhabitants ingested more
mechanically-demanding diets than later populations because they were confronted
with harsh, fluctuating environmental conditions. Furthermore, the influence of
grit-laden food suggests that a high-quality meat diet from butchering processes
could have fueled evolutionary changes in brain size.
