Delineating Regions With Permeable Boundaries In New Guinea., Terence Hays

Terence Hays

Hays sets out the linkages among communities and societies as they form networks and regions in New Guinea. Hays reminds us of the long standing concern within the recent literature from New Guinea that supports the "primitive isolates" notion that is still with us. The "my people" syndrome still plagues the legions of researchers who seek to study a small distinct population that is largely uncontaminated by outside influences and remains primitive. He paints the picture of this primitive society by describing New Guinea topographically as a land of inaccessible mountain valleys, impenetrable swamps, and remote rain forests which make …

They Are Beginning To Learn The Use Of Tobacco, Terence Hays

Terence Hays

European colonization attracts laborers whose performance was enhanced by their employers through the use of drugs. Tobacco provided Europeans a way to manipulate populations engaged in new work activities in the non-Western world. Hays argues that control of native labor was the result of control of an addictive American commercial product.

Dental Enamel As A Dietary Indicator In Mammals, Peter Lucas, Paul Constantino, Bernard Wood, Brian Lawn

Paul J. Constantino

The considerable variation in shape, size, structure and properties of the enamel cap covering mammalian teeth is a topic of great evolutionary interest. No existing theories explain how such variations might be fit for the purpose of breaking food particles down. Borrowing from engineering materials science, we use principles of fracture and deformation of solids to provide a quantitative account ofhowmammalian enamelmay be adapted to diet. Particular attention is paid to mammals that feed on ‘hard objects’ such as seeds and dry fruits, the outer casings of which appear to have evolved structures with properties similar to those of enamel. …

Predicting Failure In Mammalian Enamel, Brian Lawn, James Lee, Paul Constantino, Peter Lucas

Paul J. Constantino

Dentition is a vital element of human and animal function, yet there is little fundamental knowledge about how tooth enamel endures under stringent oral conditions. This paper describes a novel approach to the issue. Model glass dome specimens fabricated from glass and back­filled with polymer resin are used as representative of the basic enamel/dentine shell structure. Contact loading is used to deform the dome structures to failure, in simulation of occlusal loading with opposing dentition or food bolus. To investigate the role of enamel microstructure, additional contact tests are conducted on two­phase materials that capture the essence of the mineralized­rod/organic­sheath …

Adaptation To Hard-Object Feeding In Sea Otters And Hominins, Paul Constantino, James Lee, Dylan Morris, Peter Lucas, Adam Hartstone-Rose, Wah-Keat Lee, Nathaniel Dominy, Andrew Cunningham, Mark Wagner, Brian Lawn

Paul J. Constantino

The large, bunodont postcanine teeth in living sea otters (Enhydra lutris) have been likened to those of certain fossil hominins, particularly the ’robust’ australopiths (genus Paranthropus). We examine this evolutionary convergence by conducting fracture experiments on extracted molar teeth of sea otters and modern humans (Homo sapiens) to determine how load-bearing capacity relates to tooth morphology and enamel material properties. In situ optical microscopy and x-ray imaging during simulated occlusal loading reveal the nature of the fracture patterns. Explicit fracture relations are used to analyze the data and to extrapolate the results from humans to earlier hominins. It is shown …

Fracture Susceptibility Of Worn Teeth, Amanda Keown, Mark Bush, James Lee, Chris Ford, Paul Constantino, Brian Lawn

Paul J. Constantino

An experimental simulation study is made to determine the effects of occlusal wear on the capacity of teeth to resist fracture. Tests are carried out on model dome structures, using glass shells to represent enamel and epoxy filler to represent dentin. The top of the domes are ground and polished to produce flat surfaces of prescribed depths relative to shell thickness. The worn surfaces are then loaded axially with a hard sphere, or a hard or soft flat indenter, to represent extremes of food contacts. The loads required to drive longitudinal cracks around the side walls of the enamel to …

Microwear, Mechanics And The Feeding Adaptations Of Australopithecus Africanus, Paul Constantino, Craig Byron, Paul Dechow, Ian Gross, Peter Lucas, Brian Richmond, Callum Ross, Dennis Slice, Mark Spencer, Dennis Strait, Qian Wang, Gerhard Weber, Bernard Wood, Barth Wright

Paul J. Constantino

Recent studies of dental microwear and craniofacial mechanics have yielded contradictory interpretations regarding the feeding ecology and adaptations of Australopithecus africanus. As part of this debate, the methods used in the mechanical studies have been criticized. In particular, it has been claimed that finite element analysis has been poorly applied to this research question. This paper responds to some of these mechanical criticisms, highlights limitations of dental microwear analysis, and identifies avenues of future research.

Properties Of Tooth Enamel In Great Apes, Paul Constantino, Brian Lawn, James Lee, Peter Lucas, Dylan Morris, Tanya Smith

Paul J. Constantino

A comparative study has been made of human and great ape molar tooth enamel. Nanoindentation techniques are used to map profiles of elastic modulus and hardness across sections from the enamel–dentin junction to the outer tooth surface. The measured data profiles overlap between species, suggesting a degree of commonality in material properties. Using established deformation and fracture relations, critical loads to produce function-threatening damage in the enamel of each species are calculated for characteristic tooth sizes and enamel thicknesses. The results suggest that differences in load-bearing capacity of molar teeth in primates are less a function of underlying material properties …

Language And Living Things, Terence Hays

Terence Hays

Ethnobiology is often regarded as a quaint and excessively particularistic specialty, as its modern practitioners trace the complexities and subtleties of specific systems of folk classification and nomenclature. Their finegrained descriptions and elegant analyses are at once too “thick” and too “thin” for most nonspecialists, who, in any event, await syntheses of what has been learned from such inquiries, preferably in the form of comparative studies in the tradition of anthropology’s concern with generalizations that illuminate the wider human condition. Rising to this challenge, Cecil Brown has long pursued, in numerous papers and now in this book, crosscultural “uniformities” as …

Ndumba Folk Biology And General Principles Of Ethnobotanical Classification And Nomenclature, Terence Hays

Terence Hays

Brent Berlin's proposed "general principles of classification and nomenclature" are examined as they apply to folk biology in Ndumba, a Papua New Guinea hzghlands society. Focusing on Ndumba folk zoology, supplemented with a previous analysis of their folk botany, Berlin's analytical schema for ethnobiological classification is supported, but principles of nomenclature in ethnobiology appear to be in need of reconsideration.

Failure Of Treatment / Book Review, Terence Hays

Terence Hays

This is an extraordinary book, and one that I believe is unique in the literature of medical anthropology. Inspired by Victor Turner's "social drama, the extended case method" (p. 3), Gilbert Lewis presents "the ethnography of an illness" (p. 1), a detailed—sometimes day-by-day—account of a protracted illness suffered by Dauwaras, a Gnau-speaking man of the upper Sepik River in Papua New Guinea.

The Sweet Potato And Oceania, Terence Hays

Terence Hays

Debates about the introduction and diffusion of Ipomoea batatas in the Pacific have gone on for a century although largely without the benefit of a thorough botanical understanding of the plant. That is now provided in Yen’s monograph, which synthesizes the results and implications of his own two decades of research with the now massive literature on the subject.

Tzeltal Folk Zoology, Terence Hays

Terence Hays

In some respects, this volume might be viewed as a companion piece to Berlin et al.’s Principles of Tzeltal Plant Classification. It deals with the same people of highland Chiapas, Mexico, and an earlier version was Hunn’s doctoral thesis, supervised by Berlin. Nevertheless, it can also clearly stand on its own as a significant contribution to ethnology, with additional relevance to biosystematists, ecologists, linguists, and psychologists.

Gis And Paleoanthropology: Incorporating New Approaches From The Geospatial Sciences In The Analysis Of Primate And Human Evolution, Robert L. Anemone, Glenn C. Conroy, Charles W. Emerson

Robert L. Anemone

The incorporation of research tools and analytical approaches from the geospatial sciences is a welcome trend for the study of primate and human evolution. The use of remote sensing (RS) imagery and geographic information systems (GIS) allows vertebrate paleontologists, paleoanthropologists, and functional morphologists to study fossil localities, landscapes, and individual specimens in new and innovative ways that recognize and analyze the spatial nature of much paleoanthropological data. Whether one is interested in locating and mapping fossiliferous rock units in the field, creating a searchable and georeferenced database to catalog fossil localities and specimens, or studying the functional morphology of fossil …

Participation in this documentary directed by Julian Thomas and produced by Electric Sky for History Channel International.

"The legend of blood sucking vampires has captured peoples’ imagination for generations. Mysterious tales of the undead rising from their coffins to terrorise the living and drain their blood are the stuff of horror movies and novels. But a crack team of archaeologists and forensic scientists have uncovered hard evidence for the existence of the legend – a legend that continues to haunt communities in the present day…"

Messengers From The Past, Anastasia Tsaliki

Participation in this documentary directed by Gianni Minelli and produced by Zeeva Production in English and in Italian.

"On September 26th, 1997, a violent earthquake shook central Italy. The effects were devastating. Television stations from all over the world broadcasted images of the incomparable artistic heritage that risked being destroyed forever. In Monsanpolo del Tronto, a small town in the Marches, the earthquake damaged the beautiful church Maria Santissima Assunta. A few years later, during the restoration of the church, a sensational discovery was made: twenty perfectly preserved mummies from the middle of the sixteenth century wearing their original clothes. …

Longitudinal Study Of Dental Development In Chimpanzees Of Known Chronological Age: Implications For Understanding The Age At Death Of Plio-Pleistocene Hominids, Robert Anemone, Mark Mooney

Robert L. Anemone

Reconstruction of life history variables of fossil hominids on the basis of dental development requires understanding of and comparison with the pattern and timing of dental development among both living humans and pongids. Whether dental development among living apes or humans provides a better model for comparison with that of Plio-Pleistocene hominids of the genus Australopithecus remains a contentious point. This paper presents new data on chimpanzees documenting developmental differences in the dentitions of modern humans and apes and discusses their significance in light of recent controversies over the human or pongid nature of australopithecine dental development. Longitudinal analysis of …

The Vcl Hypothesis Revisited: Patterns Of Femoral Morphology Among Quadrupedal And Saltatorial Prosimian Primates, Robert Anemone

Robert L. Anemone

The descriptive and functional morphology of the postcranium of the vertical clinging and leaping prosimians is of great interest in both adaptational and phylogenetic studies of extant and extinct primates. An analysis of patterns of femoral morphology among quadrupedal and saltatory living prosimians indicates the presence of at least two, and possibly three, distinct femoral adaptations to the demands of an arboreal, saltatory existence. Osteological measurements were taken on 277 postcranial skeletons representing eight prosimian families, with skeletal trunk length (Biegert and Maurer, Folia Primatol. 17:142–156, 1972) used as an estimator of body size in both bivariate and multivariate (discriminant …
