Craniofacial Fluctuating Asymmetry in Cross River Gorillas ( Gorilla gorilla diehli )
Proposed standards for prosthetic foot reuse and considerations for donation of used prosthetic feet to low-and middle-income countries
Prosthetic components from high-income countries (HICs) are often replaced not because they are broken, but because of guidelines or expired warranties, meaning they may still be usable. As most HICs classify prostheses as single patient multi-use devices, components are often disposed of or donated to low- and middle- income countries (LMICs) where medical device regulatory frameworks are limited or non-existent. A lack of standards guaranteeing…
A reliable and inclusive method for assessing failure-causing mechanical wear in prosthetic feet
Wear assessment of prosthetic feet is critical for monitoring device performance and replacement, especially in rural or resource constrained areas where clinical follow-ups can be infrequent. Standardised, reliable methods for wear evaluation are limited. This study investigates the inter-observer reliability of a method for quantifying patterns and relative magnitudes of plantar surface wear of prosthetic feet and presents preliminary results f…
Biomechanics in anthropology
Biomechanics is the set of tools that explain organismal movement and mechanical behavior and links the organism to the physicality of the world. As such, biomechanics can relate behaviors and culture to the physicality of the organism. Scale is critical to biomechanical analyses, as the constitutive equations that matter differ depending on the scale of the question. Within anthropology, biomechanics has had a wide range of applications, from un…
Variation in enamel mechanical properties throughout the crown in catarrhine primates
Enamel mechanical properties vary across molar crowns, but the relationship among mechanical properties, tooth function, and phylogeny are not well understood. Fifteen primate lower molars representing fourteen taxa (catarrhine, n = 13; platyrrhine, n = 1) were sectioned in the lingual-buccal plane through the mesial cusps. Gradients of enamel mechanical properties, specifically hardness and elastic modulus, were quantified using nanoindentation …
The landscape of tooth shape: Over 20 years of dental topography in primates
Diet plays an incontrovertible role in primate evolution, affecting anatomy, growth and development, behavior, and social structure. It should come as no surprise that a myriad of methods for reconstructing diet have developed, mostly utilizing the element that is not only most common in the fossil record but also most pertinent to diet: teeth. Twenty years ago, the union of traditional, anatomical analyses with emerging scanning and imaging tech…
Dental topography and the diet of Homo naledi
Extant ape dental topography and its implications for reconstructing the emergence of early Homo
What did Hadropithecus eat, and why should paleoanthropologists care
Over 40 years ago, Clifford Jolly noted different ways in which Hadropithecus stenognathus converged in its craniodental anatomy with basal hominins and with geladas. The Malagasy subfossil lemur Hadropithecus departs from its sister taxon, Archaeolemur, in that it displays comparatively large molars, reduced incisors and canines, a shortened rostrum, and thickened mandibular corpus. Its molars, however, look nothing like those of basal hominins;…
Food mechanical properties and dietary ecology
Interdisciplinary research has benefitted the fields of anthropology and engineering for decades: a classic example being the application of material science to the field of feeding biomechanics. However, after decades of research, discordances have developed in how mechanical properties are defined, measured, calculated, and used due to disharmonies between and within fields. This is highlighted by "toughness," or energy release rate, the compar…
Tooth cusp sharpness as a dietary correlate in great apes
Mammalian molars have undergone heavy scrutiny to determine correlates between morphology and diet. Here, the relationship between one aspect of occlusal morphology, tooth cusp radius of curvature (RoC), and two broad dietary categories, folivory and frugivory, is analyzed in apes. The author hypothesizes that there is a relationship between tooth cusp RoC and diet, and that folivores have sharper teeth than frugivores, and further test the corre…
Functional implications of squamosal suture size in paranthropus boisei
It has been hypothesized that the extensively overlapping temporal and parietal bones of the squamosal sutures in Paranthropus boisei are adaptations for withstanding loads associated with feeding. Finite element analysis (FEA) was used to investigate the biomechanical effects of suture size (i.e., the area of overlap between the temporal and parietal bones) on stress, strain energy, and strain ratio in the squamosal sutures of Pan troglodytes an…
Viewpoints: Diet and dietary adaptations in early hominins: The hard food perspective
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…
