Recent Progress in Bioarchaeology: Approaches to the Osteological Paradox

The publication of The Osteological Paradox (Wood et al., 1992, Current Anthropology, 33:343–370) a decade ago sparked debate about the methods and conclusions drawn from bioarchaeological research. Wood et al. (1992, Current Anthropology, 33:343–370) highlighted the problematic issues of selective mortality and hidden heterogeneity in frailty (susceptibility to illness), and argued that the interpretation of population health status from skeletal remains is not straightforward. Progress in bioarchaeology over the last few years has led to the development of tools that will help us grapple with the issues of this osteological paradox. This paper provides a review of recent literature on age and sex estimation, paleodemography, biodistance, growth disruption, paleopathology, and paleodiet. We consider how these advances may help us address the implications of hidden heterogeneity in frailty and selective mortality for studies of health and adaptation in past societies.     

Trauma and pathology of a buried dog from San Nicolas Island,California, U.S.A.

To date more intact dog remains have been found on San Nicolas than on any of the other seven California Channel Islands. However, little is known about them. During the 2007 summer field season we excavated a medium sized young male dog in a flexed burial position from a pit at CA-SNI-25, a large Native American village site. The dog exhibits hypodontia, noticeable tooth attrition, severe scapular trauma, and vertebral, rib, and phalanx pathologies. Most of the injuries appear to have resulted from a severe blunt force trauma of unknown origin and it is likely the dog would not have survived without human care. The results of our analysis contribute to the, somewhat limited, published data on archaeological dogs in California. In this paper we describe the biological characteristics of the dog especially his anomalies and pathologies and compare them with published reports of other North American archaeological dogs with similar conditions.     

Multiple traumatic dental injuries: a case report in a young individual from the Samnitic necropolis of Opi Val Fondillo (VI-V century BC; Central Italy)

Traumatic dental injuries, although apparently rare in archaeological populations, can be found under certain circumstances affecting the dentition in a variety of ways. This paper contributes to the paleopathology literature by reporting one case of dental trauma. Evidence for differentiating antemortem/perimortem dental trauma from postmortem damage is presented, and it is suggested that these injuries were sustained due to an accidental fall, supported by the morphology, location and extension of the injuries and characterization of the impact. These data provide a valuable information for a reconstruction of past behaviors in the Samnitic necropolis of Opi Val Fondillo (VI-V century BC; Central Italy).     

Recent Advances in Maya Archaeology

This paper focuses on the discoveries of the last decade in Maya archaeology, and assesses their impact on previous models and synthetic frameworks. Although the bibliography includes 700 items published during the last 10 years, it is not exhaustive; on the contrary, a frustratingly large number of discoveries had to be omitted. Two areas exploding with new research are (1) the elicitation of a greater variety of data from hieroglyphic texts, and (2) a series of chemical and biological breakthroughs in the analysis of human burials. The former make it easier to assess the role of elite actors or agents in processes of sociopolitical change. The latter hold out the hope of documenting warfare (through skeletal trauma), migration (by tracing tooth enamel isotopes to ground water), status or gender differences in diet (through bone chemistry), and biological connections of individuals to each other and to earlier populations (through DNA). By combining these new data, we are on our way to integrating humanism and science, and to treating Maya polities as case studies in primary or secondary state formation.     

REPORT The British Contribution to the Neurosciences

The evolution of techniques to manage patients with head injuries has served as the basis for the treatment of other neurosurgical disorders, including brain tumors, intracranial infections, and cerebrovascular disease. In the nineteenth century, advances in anesthesia, asepsis, and cerebral localization slowly took hold and created the groundwork for modern neurosurgery. To better understand the advances in the treatment of brain injuries in the late 1800s and early 1900s, we examine relevant historical literature and, through the courtesy of the Alan Mason Chesney Medical Archives, we review Dr. Harvey Cushing's patient records (1898–1909) in the Johns Hopkins Hospital surgical archives. The original case histories of 10 patients (6 in detail) who suffered head injuries and underwent treatment by Cushing illustrate some of Cushing's early attempts at intracranial surgery. We also examine the influences on Cushing as he developed into a leader in the new era of modern neurosurgery.     

Canary islands aborigin sex determination based on mandible parameters contrasted by amelogenin analysis

Sex determination using mandible parameters is population dependent. In order to assess which measurements better characterize sex in prehispanic individuals from the Canary Islands, we blindly contrasted the results obtained by visual inspection and osteometric measurements with those obtained by molecular sexing using amelogenin ancient DNA analysis on teeth from the same material. Unambiguous sex classification was achieved by amplification of sex specific amelogenin alleles in 56 out of 76 mandibles (73.78% of the cases). Visual inspection led to a correct diagnosis in 66.04% of cases, with a greater proportion of errors for female (54.17%) than male (17.24%) mandibles. Osteometric measurements were able to assign sex correctly in 72.2% in the best of cases (mandibular height), a proportion similar to that obtained using a discriminant function (71.2%). By logistic regression analysis, ramus breadth, index ramus breadth/ramus height and mandibular length were the parameters independently related with a mistaken diagnosis of female sex, whereas bigonial width, ramus height and mandibular length were the parameters more closely and independently related to a mistaken diagnosis of male sex. In conclusion, diagnosis based on visual examination of the mandible or on its metric measurement only serves to roughly estimate sex with an accuracy of around 70% or less, at least among the prehispanic population from Gran Canaria. Amplification of amelogenin alleles leads to unambiguous identification of male and female alleles in 73.68% of cases, at least among the prehispanic population from Gran Canaria.     

Warfare in Prehistoric and Early Historic Eastern North America

Recent criticisms of the use of historically and ethnographically recorded conflicts as models for warfare in prehistoric times force archaeologists to reexamine assumptions about the frequency, severity, and effects of intergroup fighting. In eastern North America, skeletons of victims and palisaded settlements—the only information consistently available on intergroup hostilities—indicate that the prevalence of conflicts varied greatly over time and space. Occasionally the attacks, typically ambushes of small numbers of people, cumulatively resulted in numerous casualties.Variation in palisade strength is consistent with the organizational structure and warrior mobilization potential of late prehistoric societies in different parts of the Eastern Woodlands.     

Reconstructing the massacre at Fort William Henry,New York

Fort William Henry, in upstate New York, was the site of a legendary siege and massacre in 1757 during the French and Indian War. As part of the terms of surrender, the British garrison was to retreat with all their arms and possessions, thus denying the Indian allies of the French their spoils of war. Contemporaneous and fictionalized accounts of the resulting massacre have often been regarded as exaggerations of actual events. Five men buried in a mass grave within the fort, known as the crypt, however, were clearly victims of the massacre. These men were among the sick and wounded who were unable to make the 15 mile (24 km) journey to Fort Edward and were left in the care of the French. Four of the five men sustained pre-mortem leg trauma that would have resulted in their hospitalization and prevented them from walking. The other massive perimortem trauma on these remains vividly depicts the results of the massacre. Three of the five men were shot in the knee; two of these three were shot elsewhere as well. One man was decapitated. Both the front and back of all the bodies bear cut marks, probably from the use of both axes and long-bladed knives as weapons. The numerous gashes in the thoracic and pelvic regions indicate the men were mutilated. Our analysis of the remains from this mass grave confirms and enhances the historical accounts of the massacre at Fort William Henry. The skeletons of these five men provide gruesome testimony of the assault to which they were subjected.
