Any change in the energetic cost of mammalian mastication will affect the net energy gain
from foods. Although the energetic efficiency of masticatory effort is fundamental in …

As the tissue most directly responsible for breaking down food in the oral cavity, the form and
function of enamel is obviously of evolutionary significance in humans, non-human primates …

The thick-enameled, bunodont dentition shared by most early hominins has traditionally
been interpreted as reflecting durophagy, especially in the robust genus Paranthropus …

Antemortem enamel chipping in living and fossil primates is often interpreted as evidence of
hard-object feeding (ie,'durophagy'). Laboratory analyses of tooth fracture have modeled the …

When a tooth contacts a hard object with enough force, the enamel can fracture to create a
chip (Chai and Lawn, 2007; Fannin et al., 2020). The fractured area can vary depending on …

Size and shape variation of molar crowns in primates plays an important role in
understanding how species adapted to their environment. Gorillas are commonly …

Materials and methods We conducted a survey of hominin postcanine tooth chipping by
examining original fossil specimens at the National Museum of Ethiopia, the National …

Abstract Objectives Capuchin monkeys (Cebus spp. and Sapajus spp.) routinely extract food
resources that are embedded in protective matrices. Features such as relative brain size …

Objectives To test the hypothesis that differences in crown structure, enamel growth, and
crown geometry in Cercocebus and Lophocebus molars covary with differences in the …

Extractive foraging is considered a key selective pressure for the evolution of primate
cognitive abilities—the extractive foraging hypothesis. Although tool‐use and substrate‐use …
