Paranthropus aethiopicus
Paranthropus boisei
Primate dietary ecology in the context of food mechanical properties
Viewpoints
Recent biomechanical analyses examining the feeding adaptations of early hominins have yielded results consistent with the hypothesis that hard foods exerted a selection pressure that influenced the evolution of australopith morphology. However, this hypothesis appears inconsistent with recent reconstructions of early hominin diet based on dental microwear and stable isotopes. Thus, it is likely that either the diets of some australopiths include…
Measuring the Toughness of Primate Foods and its Ecological Value
Tooth Chipping as a Tool to Reconstruct Diets of Great Apes (Pongo, Gorilla, Pan)
The role of tooth enamel mechanical properties in primate dietary adaptation
Primate teeth adapt to the physical properties of foods in a variety of ways including changes in occlusal morphology, enamel thickness, and overall size. We conducted a comparative study of extant primates to examine whether their teeth also adapt to foods through variation in the mechanical properties of the enamel. Nanoindentation techniques were used to map profiles of elastic modulus and hardness across tooth sections from the enamel‐dentin …
Microwear, mechanics and the feeding adaptations of Australopithecus africanus
Adaptation to hard-object feeding in sea otters and hominins
The feeding biomechanics and dietary ecology of Australopithecus africanus
The African Plio-Pleistocene hominins known as australopiths evolved a distinctive craniofacial morphology that traditionally has been viewed as a dietary adaptation for feeding on either small, hard objects or on large volumes of food. A historically influential interpretation of this morphology hypothesizes that loads applied to the premolars during feeding had a profound influence on the evolution of australopith craniofacial form. Here, we te…
Fallback foraging as a way of life
The genus Cebus is one of the best extant models for examining the role of fallback foods in primate evolution. Cebus includes the tufted capuchins, which exhibit skeletal features for the exploitation of hard and tough foods. Paradoxically, these seemingly “specialized” taxa belong to the most ubiquitous group of closely related primates in South America, thriving in a range of different habitats. This appears to be a consequence of their abilit…
Indentation as a technique to assess the mechanical properties of fallback foods
A number of living primates feed part‐year on seemingly hard food objects as a fallback. We ask here how hardness can be quantified and how this can help understand primate feeding ecology. We report a simple indentation methodology for quantifying hardness, elastic modulus, and toughness in the sense that materials scientists would define them. Suggested categories of fallback foods—nuts, seeds, and root vegetables—were tested, with accuracy che…
The importance of fallback foods in primate ecology and evolution
The role of fallback foods in shaping primate ranging, socioecology, and morphology has recently become a topic of particular interest to biological anthropologists. Although the use of fallback resources has been noted in the ecological and primatological literature for a number of decades, few attempts have been made to define fallback foods or to explore the utility of this concept for primate evolutionary biologists and ecologists. As a prefa…
The influence of fallback foods on great ape tooth enamel
Lucas and colleagues recently proposed a model based on fracture and deformation concepts to describe how mammalian tooth enamel may be adapted to the mechanical demands of diet (Lucas et al.: Bioessays 30 2008 374‐385). Here we review the applicability of that model by examining existing data on the food mechanical properties and enamel morphology of great apes ( Pan , Pongo , and Gorilla ). Particular attention is paid to whether the consumptio…
Mechanical Properties of Plant Underground Storage Organs and Implications for Dietary Models of Early Hominins
The Evolution of Zinjanthropus boisei
Many people assume that OH 5, the type specimen of Paranthropus boisei, collected in 1959, was the first evidence of that taxon to be found, but OH 3, recovered in 1955, predated the discovery of OH 5 by four years. Thus, Paranthropus boisei recently celebrated the equivalent of its fiftieth birthday. This review marks that milestone by examining the way our understanding of this taxon has changed during its fifty, or so, year history
Paranthropus boisei
Paranthropus boisei is a hominin taxon with a distinctive cranial and dental morphology. Its hypodigm has been recovered from sites with good stratigraphic and chronological control, and for some morphological regions, such as the mandible and the mandibular dentition, the samples are not only relatively well dated, but they are, by paleontological standards, reasonably-sized. This means that researchers can trace the evolution of metric and nonm…
