In order to reconstruct relationships between cave burials in the Meuse River Basin of Belgium during the Middle to Terminal Neolithic, dental remains from five sites are compared. Because molar morphology and the presence or absence of nonadaptive dental traits are highly heritable and biologically neutral, they can potentially yield clues as to the chronological and spatial relationships between sites and the variation within these collective burials. Dental microwear is brought to bear on the dietary proclivities of the individuals represented in the caves and is compared to the variation in molar morphology.
