A Comparison of Radiological and Palaeopathological Diagnostic Criteria for Hyperostosis Frontalis Interna

Hyperostosis frontalis interna (HFI) is a common clinical finding in post-menopausal women, less often in men. The characteristic billowing symmetrical new bone formation is found on the endocranial surface of the skull and rarely causes any significant symptoms. In clinical medicine HFI is diagnosed from its X-ray appearance, whereas in palaeopathology it is diagnosed by direct observation of the skull. There are no standard palaeopathological criteria to diagnose HFI. In past populations HFI appears to be much less common than today, with modern prevalences of up to 70 per cent of women over 40 affected, compared with archaeological prevalences of between 1 and 4 per cent. This discrepancy has been attributed to a younger mean age at death in ancient populations. This study aims to test the hypothesis that the difference in prevalence may be due in part to the differential nature of diagnosis between the two disciplines. A sample of 85 skulls was X-rayed, and the presence of HFI was recorded using radiological criteria. Using this method the results showed a marked increase in the number of cases of HFI to 31 per cent in females in the ancient population. © 1997 by John Wiley & Sons, Ltd. Int. J.

A palaeo-opportunistic brachiopod from the Early Permian of Argentina

Neochonetes sp. (Brachiopoda, Chonetoidea) is recorded from the middle to upper part of the early Permian Río del Peñón Formation, Río Blanco Basin, La Rioja, Argentina. It can be recognised as an r-strategist based on distribution, facies, morphological and ontogenic data which agree with the criteria proposed by Levinton and Alexander for recognising palaeo-opportunistic brachiopods. The new record of an opportunistic chonetid suggests that the group may have evolved this adaptative strategy during the late Palaeozoic.     

Essentials in the use of mycolic acid biomarkers for tuberculosis detection: response to “High-throughput mass spectrometric analysis of 1400-year-old mycolic acids as biomarkers for ancient tuberculosis infection” by

High molecular weight long-chain mycolic acids are key structural components of the cell envelope of Mycobacterium tuberculosis and they are established as biomarkers for the identification of both ancient and modern tuberculosis. Mycolic acids from M. tuberculosis have a characteristic profile, reflecting contributions from five major distinct homologous series of mycolate structural types. Diagnosis of tuberculosis in archaeological material, using mycolic acid biomarkers, depends on objective recognition of the key characteristic mycolic acid components. A recent article in this journal claimed that tuberculosis could be confirmed in ancient bones by high throughput mass spectrometric analysis of mycolic acids. Scrutiny of the data presented reveals no convincing evidence for the presence of mycolic acids, characteristic of the M. tuberculosis complex, in the skeletal remains examined. This communication reviews the essential criteria necessary for positive tuberculosis diagnosis, using mycolic acids.     

The Elusive Maya Marketplace: An Archaeological Consideration of the Evidence

The modeling of ancient Maya economies has been a dynamic area of archaeological research in the past few decades, but in most cases there has been little attention on how goods actually changed hands. Through an overview of the literature, this paper considers marketplace exchange as one mechanism of distribution. Researchers have proposed a number of physical features and artifact characteristics that may be expected in association with marketplace activity, and new methods of data collection have been offered that can be used to build a case for marketplace exchange. What remains is the challenge of developing strategies to identify ancient Maya marketplaces convincingly through archaeological excavation.     

Spinal degenerative lesions and spinal ligamentous ossifications in ancient Chinese populations of the Yellow River Civilization

Rheumatological diseases, whether inflammatory or degenerative, are ubiquitous among modern Asian people but very few palaeopathological studies have been performed in Asia on this subject. Since 1996, we have been carrying out a palaeoepidemiological survey of rheumatic diseases in ancient Chinese and Japanese skeletal populations. Findings on the spinal column in ancient Chinese populations (ca. 5000 bc –ad 1644) in Henan Province (centre of the Yellow River Civilization) are reported in this study. The examined number of the people over 20 years old was 365 (185 males, 169 females and 11 unsexed). Of these, 248 were young adults, 98 were middle adults and 19 were old adults. Crude prevalence (number/100) in total population of vertebral osteophytosis/facet osteoarthritis was 17.5/7.7, 17/3.7 and 44.6/21.1 at the cervical, thoracic and lumbar spine, respectively. That of ossified anterior longitudinal ligament (OALL) or Forestier's disease was around 3 at each of the cervical, thoracic and lumbar spine. Ossification of the posterior longitudinal ligament (OPLL) of the cervical spine was observed in five out of 114 skeletons with cervical spine preserved, while it did not exist in any thoracic and lumbar segment. Ossification of the ligamentum flavum (OLF) was predominantly observed in the thoracic spine, the crude prevalence of which was 36.7. Overall spinal degenerative lesions seemed to have been more prevalent and spinal ligament ossifications less prevalent in ancient Chinese populations than in modern people. None of the inflammatory lesions like rheumatoid spondylitis, as well as seronegative spondyloarthropathies, were detected. This is the first palaeopathological study in which the prevalence of OPLL and OLF, the two clinically important spinal ligamentous ossifications causing myelopathy in modern mankind, was surveyed in ancient skeletons.

Trepanation in Italy: A Review

This paper reviews and discusses cases of skull trepanation in ancient Italy on the basis of information provided by the literature. A total of 54 individuals from 43 different Italian archaeological sites were found to have evidence of trepanation. The analysis of evidences of trepanation in Italy has demonstrated that no differences can generally be perceived between the trepanned individual and the social context of the burial, leading to exclude a special role of the former within the group. Trepanation in Italy covers a time span of approximately 7000 years, the most ancient cases dating back to the fifth millennium bc and the most recent to the 18th–19th centuries ad . The geographic distribution appears quite homogeneous, with a prevalence of cases in Central Italy and abundant evidence from prehistoric Sardinia. The majority of individuals show a single trepanation, whereas others present skulls with multiple holes. Trepanation in Italy was reserved to adult individuals, except for some rare cases, and shows a relevant preponderance for the male sex. The most diffused technique is scraping; cutting and drilling are less attested, especially as unique techniques for trepanation, but they were used more frequently in combination with scraping. Trepanation could in some cases be hypothesised as therapeutic intervention for the treatment of a traumatic wound or of other pathologies, whereas in other cases, a number of evidences are attested of trepanation performed as probable ritual intervention or as experimental surgery; in the remaining cases, the reasons for trepanation are unclear or not determinable. A high percentage of long‐term healing associated with trepanation has been evidenced. Copyright © 2017 John Wiley & Sons, Ltd.     

Brazil's Bolsa Família: A Double‐Edged Sword?

In common with most Latin American countries, as governments embrace safety nets to attack poverty, conditional cash transfer (CCT) programmes have become part of mainstream social policy in Brazil. Under president Fernando Henrique Cardoso (1995–2002), and especially since Luiz Inácio Lula da Silva took office in 2003, targeted assistance in education, health and nutrition, now united under Bolsa Família, have expanded rapidly to benefit forty‐four million (24 per cent of the total population), absorbing almost two‐fifths of the social assistance budget earmarked for the poorest sectors. Despite its operational problems, Bolsa Família appears to have been effective in providing short‐term relief to some of the most deprived groups in Brazil. Yet it could prove to be a double‐edged sword. There is a risk that, due to its popularity among both the poor and Brazil's politicians, Bolsa Família could greatly increase patronage in the distribution of economic and social benefits and induce a strong dependence on government handouts. There are also early signs that it may be contributing to a reduction in social spending in key sectors such as education, housing and basic sanitation, possibly undermining the country's future social and economic development.     

Ancient Maya Agricultural Installations and the Development of Intensive Agriculture in NW Belize

Abstract

Archaeological study of the spatial arrangement of agricultural features such as terraces and berms yields insight into the scale, mode, and tempo of farm production and the social organization of farming communities. Data from five regions of the Maya lowlands where such features have been extensively documented demonstrate the range of strategies employed by the ancient Maya to organize agricultural production. In some previously studied regions of the lowlands, spatial patterns suggest centralized management of farmland by state institutions, while in others a smallholder strategy seems evident. In the Río Bravo region of NW Belize, the organization of agricultural labor centered neither on the state nor on the individual farm family, but on the farm community. Moreover, the incremental conversion of open lands to terraced agricultural fields was part of a long-term interactive sequence of environmental change and human response over centuries of occupation. This sequence demonstrates that the ancient Maya not only adapted to a degraded environment but used it to their advantage, developing new technologies that were successful for several centuries prior to their ultimate failure. The agricultural history of the lowland Maya demonstrates that indigenous systems of resource management in fragile environments such as the tropics were not always deleterious. The innovations and successful adaptations of ancient farmers should also be recognized.     

Congenital anomalies of the vertebral column: a case study on ancient and modern Egypt

The aim of this paper is to identify the frequency of congenital anomalies of the vertebral column in ancient Egyptians. The material for this study consisted of 272 skeletons excavated from Giza and belonging to the Old Kingdom (the time of the early pyramid builders). The vertebral columns of these skeletons were examined for the different types of congenital anomalies that affect the vertebrae. Nine cases (3.33%) were affected with spina bifida occulta, while six cases (2.22%) had transitional vertebrae at the lumbosacral joint. These frequencies are compared with other ancient populations.

Thalassaemia: Its diagnosis and interpretation in past skeletal populations

The diagnosis of thalassaemia in archaeological populations has long been hindered by a lack of pathogonomic features, and the non‐specific nature of cribra orbitalia and porotic hyperostosis. In fact, clinical research has highlighted more specific diagnostic criteria for thalassaemia major and intermedia based on changes to the thorax (‘rib‐within‐a‐rib’ and costal osteomas). A recent re‐examination of 364 child skeletons from Romano‐British Poundbury Camp, Dorset revealed children with general ‘wasting’ of the bones and three children who demonstrated a variety of severe lesions (e.g. zygomatic bone and rib hypertrophy, porotic hyperostosis, rib lesions, osteopenia and pitted diaphyseal shafts) that are inconsistent with dietary deficiency alone, and more consistent with a diagnosis of genetic anaemia. Two of these children displayed rib lesions typical of those seen in modern cases of thalassaemia. The children of Poundbury Camp represent the first cases of genetic anaemia identified in a British archaeological population. As thalassaemia is a condition strongly linked to Mediterranean communities, the presence of this condition in a child from England, found within a mausoleum, suggests that they were born to wealthy immigrant parents living in this small Roman settlement in Dorset. This paper explores the diagnostic criteria for genetic anaemia in the archaeological literature and what its presence in ancient populations can contribute to our knowledge of past human migration.

Pre‐Columbian Tuberculosis in Northwest Argentina: Skeletal Evidence from Rincón Chico 21 Cemetery

Systematic excavation of collective burial sites makes possible the recovery of skeletal series which may show bony evidence of infectious pathological conditions. This paper presents the first evidence of the existence of tuberculosis in prehistoric populations of NW Argentina with a subsistence economy based on agriculture and pastoralism. The study was carried out on individuals from Rincón Chico 21 cemetery, a burial site located in the Santa María Valley, Catamarca, used between the Late Ceramic Period and the onset of the Inca empire expansion (AD 1000–1400). Six individuals out of the 70 so far excavated showed destructive lesions in the vertebral bodies and periosteal reactions in other bones. The morphology and distribution of bone lesions led us to rule out several diseases from a broad spectrum of possible diseases that could have affected the skeletal system. Thus, the lesions were interpreted as caused by mycobacterial infections (Mycobacterium tuberculosis Complex). Considering previous studies on the dynamics of biocultural interactions which take into account information related from contextual associations and chronology, we can conclude that a tuberculosis‐like disease was present in prehistoric populations from NW Argentina.

Size and shape of the Eurasian wild boar (Sus scrofa), with a view to the reconstruction of its Holocene history

Abstract

A large assortment of skulls and skeletons of recent wild boar (Sus scrofa) from across the world has been used to collect tooth and bone measurements that can be compared to those from archaeological specimens. The data provide useful information for a reconstruction of the Holocene history of the species. The evidence collected so far highlights the great variability of the species and provides a baseline to be used for the interpretation of ancient material. It is shown that not only the size, but also the shape of teeth and mandibles can help in highlighting patterns of variability in wild boar from different areas. A number of geographic trends are identified in the variation of S. scrofa across its range, mainly concerning the differentiation of insular forms, and the existence of South–North and West–East clines. Other factors such as hybridisation with domestic stock, feralisation and human-induced movement of animals may also play an important role. A comparison with ancient material emphasises the existence of similarities as well as differences between modern and ancient populations. Although some of the geographic trends identified on the basis of the analysis of modern material seem to date back to early Holocene times, the morphological history of the species appears to be complex, and in more than one area fluctuations in body size seem to have occurred.     

Evaluation of carnivory in inland Jomon hunter–gatherers based on nitrogen isotopic compositions of individual amino acids in bone collagen

Archaeological studies including stable carbon and nitrogen isotope analyses of bone collagen from human remains have suggested their heavy dependence on terrestrial foods during the Jomon period in the inland central region in Japan. However, it is not easy to quantitatively evaluate the extent of carnivory for archaeological human remains based on the bulk collagen chemistry, because of variable ¹⁵N-enrichment factor along the trophic step and background isotopic variations in ecosystems. In order to overcome these problems and more precisely evaluate diets of prehistoric humans who strongly adapted to terrestrial environment, in this study we applied nitrogen isotope analysis of individual amino acids in bone collagen to two inland human populations in the Jomon period. Our results suggest that the two populations were predominantly dependent on the C₃-plant-based terrestrial ecosystem and consumed little aquatic resources. Furthermore, their mean trophic positions (2.7 for both cases) are closer to that of the fox (2.8–3.0) rather than those of pure herbivores (2.0–2.2), and show little change over time. These results are the first evidence that inland Jomon populations may have had more carnivorous diets than is traditionally considered.     

Deficiencies and challenges in the study of ancient tuberculosis DNA

We explore the standards of research and reporting needed to justify the destructive analysis of archaeological human bone for biomolecular studies of ancient tuberculosis (TB). Acceptable standards in osteological interpretation have been met in some biomolecular papers, but there are also cases where insufficient care has been taken in distinguishing between pathognomonic lesions and those that are ‘consistent with’ a diagnosis of TB. Some biomolecular studies have failed to recognize that archaeological bones might be contaminated with environmental mycobacteria whose DNA could give rise to false positives in polymerase chain reactions directed at members of the Mycobacterium tuberculosis complex. The difficulties of applying spoligotyping to ancient DNA have also been underestimated and conclusions drawn from such analyses are often weakly supported. Assumptions that mycobacterial DNA preserves better than human DNA, and that contamination with modern DNA is less of a problem, has led in some cases to a laxity in research standards with insufficient attention paid to the need to authenticate ancient DNA results. We illustrate our concerns by reference to a recent paper reporting biomolecular detection of ancient TB DNA in skeletons from the eastern Mediterranean Neolithic settlement of Atlit-Yam. We are unconvinced that the skeletal evidence presented in this paper gives sufficient indication of TB to warrant destructive analysis, and we are concerned that during the biomolecular part of the project inadequate attention was paid to the possibility that results might be due to laboratory cross-contamination or to amplification of environmental mycobacterial DNA present in the bones.     

Comparative Study of Perimortem Weapon Trauma in Two Early Medieval Skeletal Populations (AD 400–1200) from Ireland

Violence was a reality of life in early medieval Ireland (AD 400–1200). Its omnipresence is indicated from numerous narratives of regicide, mortal conflicts, battles and warfare that survive in ancient myths, legends and annalistic accounts. The archaeological evidence of violence and conflict is mainly identified in the osteoarchaeological record, and approximately 13% of all skeletal populations from excavated early medieval cemeteries in Ireland have shown evidence of weapon trauma. This study considers the osteological representation of violent deaths in two contemporaneous Irish skeletal populations dating to this period: Mount Gamble in County Dublin and Owenbristy in County Galway. This analysis involves assessing the different anatomical regions of the body for evidence of lesions that can be attributed to weapon trauma. The results indicate that these populations are likely to have been exposed to violence under differing circumstances; the evidence suggests that the individuals from Mount Gamble may have been well equipped or skilled at interpersonal battle, in contrast to the majority of individuals from Owenbristy who may have been unprotected and unprepared. The presence of two adolescents and two adult females amongst the victims from the latter population gives insight into a wider social dimension of weapon trauma in early medieval Ireland. There is also evidence of postmortem mutilations and decapitations, which reflect ritualistic aspects of violence. Copyright © 2012 John Wiley & Sons, Ltd.     

The periodontal disease status of the historical population of Assos

The science of anthropology obtains data on health, disease and death from ancient populations. Research on the skeletal remains of human teeth and surrounding tissues provides useful information on the evolutionary perspective of dental and periodontal diseases. The aim of this study was to determine the prevalence and severity of periodontal diseases in the skeletal remains of 33 Assos inhabitants of the 4th century BC. Three age groups were constituted for the studied population. Periodontal disease status was determined based on the textural and architectural variations of the interdental septum and the extent of bone loss. It was found that the prevalence of periodontal diseases increased with age. The severity of periodontal bone loss also increased with age and the mean alveolar bone loss between age groups was statistically significant (P = 0.004). This analysis of the dental health of ancient populations provides insights into the aetiology, patterns and distribution of periodontitis, which has a very complex disease pathogenesis.

Rice archaeological remains and the possibility of DNA archaeology: examples from Yayoi and Heian periods of Northern Japan

Japanese rice cultivation in paddy fields has 2,400∼3,000 years of history. Most of modern Japanese rice varieties are classified as Temperate-japonica (Tm-J). Few landraces are recognized as Tropical-japonica (Tr-J) only in southwestern Japan. However, ancient DNA studies and phytolith analysis suggest that Tr-J strains were more popular in the past than now. Maekawa is a complex archaeological site composed of paddies dated from the Yayoi (2,100 years BP) to the Heian (1,100 years BP) periods. Phytolith analysis indicates that intensive rice cultivation was practiced in both periods, but there was no cultivation in the intervening period. Morphological features of bulliform phytoliths suggest that Tr-J was cultivated during both periods. Locally, rice cultivation during the Heian period was brought to a close by a flood event, in which immature rice plants were pulled down and buried in silt to be preserved in a quasi-carbonized/ waterlogged state. Ancient DNA (aDNA) analysis of the carbonized plant culm from Heian Maekawa recovered chloroplast DNA sequences of the 6C7A plastid subtype, which is common to both Tr-J and Tm-J, whereas two plastid subtypes, such as 6C7A and also 7C6A, were found in aDNA of carbonized grains from the Tareyanagi site of the Yayoi period. The latter plastid subtype was specific only to Tr-J. In order to better characterize the past rice populations, modern landraces collected in the local area were classified with morphophysiological traits. Some of the landraces were found to carry several traits of Tr-J, including bulliform phytolith types, but mixed with Tm-J traits. Based on the discontinuous distribution of rice phytoliths between the Yayoi and the Heian period, the early introduction of rice cultivation may have been discontinuous and locally reintroduced after a ∼1,000-year hiatus, but with a genetically different rice population. Such populations were composed from Tr-J like strains as shown by landraces but with reduced diversity in plastid types. Through such changes, since the Yayoi era, Tr-J was largely replaced by Tm-J, although ancient Tr-J continued to participate in the genetic makeup of later rice populations and may have aided the local adaptation of introduced Tm-J.     

Are new patterns of low‐income distribution emerging in Canadian metropolitan areas?

Recent studies on urban poverty in Canadian cities suggest a growing spatial concentration of poor populations within metropolitan regions. This article assesses trends in the intra‐urban distribution of the poor population from 1986 to 2006 in eight of Canada's largest cities. We consider five well‐known dimensions of segregation, as identified by Massey and Denton (1988) , in order to examine changes in the spatial distribution of poor populations within metropolitan areas: evenness, exposure, concentration, clustering, and centralization. These indices were calculated for low‐income populations at the census tract level using data from five Canadian censuses. Although each metropolitan area has distinctive characteristics, we were able to identify some general trends. The results suggest that, in 2006 compared to 1986, low‐income populations lived in more spatially concentrated areas, which were, at the same time, socioeconomically more homogeneous and more dispersed throughout the metropolitan area. In addition, we observed that over the last twenty years areas of poverty have been located, for the most part, in neighbourhoods adjacent to downtown cores. Nevertheless, we found that poverty has mostly increased in suburban areas located outside inner‐city neighbourhoods. Growing socioeconomic homogeneity and dispersion of low income areas in metropolitan areas reveal new spatial patterns of urban poverty distribution. These findings should be cause for concern as social isolation in the most disadvantaged neighbourhoods could affect the life chances and opportunities for the residents of those areas.     

New evidence for Bronze Age agricultural settlements in the Zhunge’er (Junggar) Basin,China

Abstract

The Zhunge’er (Junggar) Basin in northern Xinjiang was a key crossroads in antiquity for the dispersal of ideas and technological innovations from the Eurasian steppe into the heartland of central China. The Bronze Age chronology of the Zhunge’er Basin is chiefly based on relative dating and little is known about subsistence strategies, although the strong tradition of nomadic and transhumant pastoralism among modern populations suggests that there may have been a high degree of mobility. The visibility of ancient cemeteries and the need to salvage graves before they are looted have resulted in a lack of focus on settlements, with a consequent assumption that in antiquity agriculture played a limited role. This assumption has been challenged by rescue excavations at the Jimusa’er (Jimsar) Luanzagangzi site, which indicate that agriculture may have been a significant component of Bronze Age subsistence strategies. Small-scale soundings at settlement sites provide well-stratified sequences of material for absolute dating which can be used to place the artifacts recovered from graves in a more secure chronological context.     

Reconsideration of criteria for differentiating faunal assemblages accumulated by hyenas and hominids

Zooarchaeologists have established several criteria for differentiating hominid‐ and hyena‐derived faunal assemblages. In some cases, however, the patterns of skeletal part representation and bone surface modification on which these criteria are ultimately based have been observed in fossil bone assemblages of unknown origin, rather than in modern assemblages of known origin. When the proposed criteria are evaluated within an actualistic framework, only three are able to differentiate between hominid‐ and hyena‐created faunal assemblages. I suggest that only these three criteria—proportions of carnivores to ungulates in the assemblage, the preserved condition of long bone specimens (either as whole cylinders or as splintered shaft fragments), and the types of bone surface modifications—should be retained as important factors in a diagnosis of the ancient bone‐collector. The remaining four criteria—the relative proportion of horn pieces in the assemblage, the relative representation of podial bones, the relative representation of small and large bovid skeletal parts, and bovid mortality profiles—are not relevant or applicable to the problem of differentiating hominid‐ from hyena‐derived faunal assemblages.
