Schistosomiasis has been deemed "the most important water-based disease from a global public-health perspective" in modern populations. To better understand the burden of schistosomiasis in ancient populations, we conducted immunologic examinations of desiccated tissue samples from two ancient Nubian populations, Wadi Halfa (N = 46) and Kulubnarti (N = 191). Saqia irrigated agriculture increases the available habitat for the aquatic vector snails and the risk of exposure. On the basis of evidence regarding the impact of saqia irrigation on schistosomiasis prevalence and transmission in modern populations, we predicted that the prevalence of Schistosoma mansoni infection would be higher in Wadi Halfa (saqia irrigation) than Kulubnarti (annual flooding). We also predicted that peak infection prevalence would occur at an earlier age within the Wadi Halfa population than the Kulubnarti population and that in both populations the prevalence of schistosomiasis would be higher in males than females due to differential water contact. The prevalence of S. mansoni was greater in the Wadi Halfa population (26.1%) than at Kulubnarti (9.4%) (P = 0.002). However, peak prevalence of infection did not occur in a younger age category within the Wadi Halfa population; prevalence of infection peaked at 66.7% in the mature adult age group (46+ years) in the Wadi Halfa population and at 16% in the later child age group (6-10 years) in the Kulubnarti population. There were no statistically significant differences in prevalence between males and females of either population. The impact of human alteration of the environment on the transmission of schistosomiasis is clearly shown in these populations. 相似文献

Long bone growth is analyzed for 180 children from a Medieval population at Kulubnarti in Sudanese Nubia (550–1450 A.D.). A regional interpopulation comparison is made with growth data from Wadi Halfa in Lower Nubia, and an intrapopulation analysis is undertaken to assess diachronic changes in growth at Kulubnarti. Changes in growth patterns are interpreted in the context of mortality and morbidity profiles and relationships between the three variables are discussed. It is suggested that changes in the sociopolitical environment may have been responsible in part for altering levels of biological stress and impacting growth. 相似文献

Human remains from two cemeteries at Kulubnarti in Sudanese Nubia present an ideal opportunity to assess the biological impact of political and economic change. Remains from the early cemetery come from Nubia's medieval period, characterized by political unification and important achievements in art and architecture. Remains from the second cemetery come from the later emergent feudal age, characterized by regional isolation and return to a subsistence economy. Patterns of mortality, growth, development, nutrition, and disease revealed by the remains converge on one conclusion: the transformation from the medieval to the feudal age at Kulubnarti witnessed an improvement in human health and survival. 相似文献

One of Denmark's earliest Christian cemeteries is Kongemarken, dating to around AD 1000-1250. A feature of early Scandinavian Christian cemeteries is sex segregation, with females buried on the northern sides and males on the southern sides. However, such separation was never complete; in the few early Christian cemeteries excavated in Scandinavia, there were always a few males placed on the north side, and some females on the south side. At Kongemarken, several males with juxtaposed females were found on the north side of the cemetery. Thus, to evaluate possible kinship relationships, and more general questions of population affinity, we analyzed mitochondrial DNA extracted from nine individuals excavated in two different areas within the cemetery: one male and four females from Area 1, and one male and three females from Area 2. Using stringent laboratory protocols, each individual was unequivocally assigned to a mitochondrial haplogroup. A surprising amount of haplogroup diversity was observed (Area 1: 1 U7 (male), 1 H, 1 I, 1 J, and 1 T2; Area 2: 2 H, 1 I, and 1 T, with one H being male); even the three subjects of haplogroup H were of different subtypes. This indicates that no subjects within each area were maternally related. The observed haplogroup, U7, while common in India and in western Siberian tribes, was not previously observed among present-day ethnic Scandinavians, and haplogroup I is rare (2%) in Scandinavia. These observations suggest that the individuals living in the Roskilde region 1,000 years ago were not all members of a tightly knit local population and comprised individuals with genetic links with populations that were from much farther away. 相似文献

Fluctuating asymmetry is commonly used as a bioindicator of developmental stress. This study addresses asymmetry under nutritional/systemic stress in the human craniofacial skeleton and its utility as an indicator of developmental instability. Crania from the diachronic Christian cemeteries at Kulubnarti (Sudanese Nubia) were chosen as a model for nutrition/systemic stress. Previous studies indicate that individuals from the Early Christian cemetery were subjected to greater developmental stress when compared with individuals from the Late Christian cemetery. Therefore, crania from the Early Christian cemetery should display a greater magnitude of fluctuating asymmetry than crania from the Late Christian cemetery. Thirty adult crania of comparable age and sex were selected from each population. Landmark coordinates were digitized in two separate trials and averaged to minimize error. Euclidean distance matrix analysis (EDMA) was used to measure and compare the magnitude of fluctuating asymmetry in each sample. Results indicate that crania from the Early Christian cemetery display greater amounts of fluctuating asymmetry than those from the Late Christian cemetery, as predicted. The degree of fluctuating asymmetry for each linear distance is highly correlated between the cemeteries, suggesting that all humans may share common patterns of fluctuating asymmetry in the skull. In contrast, there is little correlation between magnitude of fluctuating asymmetry and length of linear distance, between-subject variability, or measurement error. These results support the hypothesis that poor nutrition/systemic stress increases developmental instability in the human skull and that increased fluctuating asymmetry constitutes morphological evidence of this stress. 相似文献

From Meroitic to Christian times (350 B .C .–A .D . 1400), Sudanese Nubia experienced political, economic, cultural, and environmental upheaval. Change in any one of these aspects of ancient lifeways can affect subsistence. Dietary patterns from this period are reconstructed by measuring stable carbon and nitrogen isotope ratios in tissue samples from 146 mummies excavated from five sites in the Wadi Halfa area. On average, δ13C values of bone collagen, muscle, and skin indicate high consumption levels of C3 plants (presumably wheat or barley staples, mixed vegetables, and fruits) throughout the sequence. However, during the X-Group period (A .D . 350–550), there is a statistically significant increase in consumption of C4 plants (millet or sorghum), which are predominant in both the archeological record and in modern crop production for most of the Northern Sudan. The X-Group period was also associated with a low Nile and political and economic restructuring. Increased use of C4 plants on a seasonal basis is also indicated by shifting δ13C values along hair shafts for both X-Group and Christian periods. δ15N values suggest that the major source of protein for all time periods came from herbivorous animals. A small, but significant increase in 15N over the 1,000-year sequence could be the result of fertilization. © 1994 Wiley-Liss, Inc. 相似文献

Archaeological evidence supports the inhabitation of the Lake Baikal region since the Paleolithic. Both metric and nonmetric osteological studies suggest that Neolithic Cis-Baikal populations are the ancestors of contemporary inhabitants of the region. To date, ancient DNA data have not been used to corroborate this biological continuity hypothesis. This study presents a temporal snapshot of the Cis-Baikal Neolithic by examining mtDNA diversity in two cemetery populations situated on the Angara River downstream of Lake Baikal. The 800 years separating the use of the two cemeteries is thought to represent a biocultural hiatus in the Cis-Baikal region, one that ended when a new group migrated into the area. To assess the likelihood that genetic continuity exists between these two Neolithic groups, we examined both mtDNA coding region and hypervariable region I (HVI) polymorphisms from skeletal remains excavated from both cemeteries (Lokomotiv and Ust'-Ida). The mtDNA haplogroup distributions of the two cemetery populations differ significantly, suggesting that they were biologically distinct groups. When the biological distance between these Neolithic groups is compared with modern Siberian and other East Eurasian groups, the posthiatus group (Serovo-Glazkovo) generally aligns with contemporary Siberians, while the prehiatus (Kitoi) individuals are significantly different from all but modern Kets and Shorians living in the Yenisey and Ob River basins to the west of Lake Baikal. These results suggest that the Lake Baikal region experienced a significant depopulation event during the sixth millennium BP, and was reoccupied by a new immigrant population some 800 years later. 相似文献

Functional analysis of the true pelvis (defined as that portion lying below and including the pelvic brim) was undertaken on a sample of 36 females from the Medieval site of Kulubnarti in Sudanese Nubia. Standard obstetric measurements were taken and compared to four additional prehistoric skeletal samples and to modern American standards for the same obstetric dimensions. Relative to the other prehistoric populations, the Kulubnarti pelves are smaller in most dimensions and, when compared to modern American standards, from one-third to one-half would be diagnosed as contracted in one or more planes. Given the meager, fluctuating resources of these Medieval Nubians' harsh desert environment, pelvic size reduction is a likely result of body size reduction as one biological response to nutritional stress (Mittler and Van Gerven, 1989; Moore et al., 1986; Van Gerven et al., 1981). It is argued, however, that size reduction created a high potential for either maternal-neonatal morbidity and mortality due to fetopelvic disproportion or neonatal loss due to low birth weight. In either case, it is suggested that the Kulubnarti population paid a significant biological price for this aspect of size reduction. 相似文献

The analysis of traumatic fractures can provide valuable information concerning the affects of sociopolitical factors upon
the health of prehistoric populations. However, such information can only be acquired by implementing a quantitative demographic
approach. The present research applies such a method to longbone fractures in two medieval Christian populations excavated
from ancient Nubia. Long-bones of two hundred and eighteen individuals from an early (550 to 750 A.D.) Christian cemetery
and 188 individuals from a late (750 to 1450 A.D.) Christian cemetery were examined for evidence of traumatic fracture. Analysis
included a determination of fracture rates, age and sex related fracture patterns, and rate of fracture per years at risk.
The results of this study indicate that the majority of fractures in both cemeteries were likely caused by accidental falls.
Fractures resulting from direct (possibly interpersonal) violence were found in both samples, though at a higher frequency
in the early Christian population (27% versus 16%). Middle-aged adults (particularly males) of the early cemetery exhibited
a higher than expected risk to fractures indicating an activity related cause of injury. In contrast, the late Christian population
showed a marked increase in fractures among both children and the elderly. This distribution may reflect changes in health
and residential architecture which occurred during the late Christian period. 相似文献

The present research represents a comparison of dental and skeletal development as a means for determining nutritional stress
in a Medieval Christian population from Nubia’sBatn el Hajar. The sample consists of 21 individuals from an early Christian (c 550–750) and 23 individuals from a late Christian cemetery (c mid-16th century) excavated from the site of Kulubnarti, Sudan. Ages at death ranged from 12 to 23 years. For the combined
sample, a large majority (70.5%) of individuals had skeletal ages younger than their dental ages. However, a comparison of
those individuals that could be sexed revealed that the pattern was not consistent for males and females. Females showed no
difference between skeletal and dental age while males showed significant skeletal retardation. This pattern of sex differences
is consistent with that observed for modern living children and subadults experiencing nutritional stress. A comparison by
cemetry also suggests a reduction in stress from early to late Christian times with later Christians showing a closer correspondence
between skeletal and dental ages. While not statistically significant, this apparent reduction is consistent with previous
research on the subadult remains. 相似文献

A biological affinities study based on frequencies of cranial nonmetric traits in skeletal samples from three cemeteries at predynastic Naqada, Egypt, confirms the results of a recent nonmetric dental morphological analysis. Both cranial and dental traits analyses indicate that the individuals buried in a cemetery characterized archaeologically as high status are significantly different from individuals buried in two other, apparently nonelite cemeteries and that the nonelite samples are not significantly different from each other. A comparison with neighbouring Nile Valley skeletal samples suggests that the high status cemetery represents an endogamous ruling or elite segment of the local population at Naqada, which is more closely related to populations in northern Nubia than to neighbouring populations in southern Egypt. © 1996 Wiley-Liss, Inc. 相似文献

This study examined the efficacy of bilateral asymmetry in epiphyseal union as an indicator of environmental stress affecting the skeleton. We compared the extent of asymmetry in the postcranial skeleton between two cemetery samples excavated from Medieval Kulubnarti, Sudanese Nubia. Past studies have strongly suggested that these ancient Nubians experienced environmental stress-the early Christian period (550-750 AD) population to a greater extent than the late Christian period (750-1450 AD) population. We hypothesized that if bilateral asymmetry is a reflection of stress, then it should be present or greater in the more stressed population, the early Christian period population, while absent or found to a lesser extent in the less stressed population, the late Christian period population. We computed two mean values, representative of right-side and left-side epiphyseal union, for each individual in both cemetery samples, and tested for significant differences. Bilateral asymmetry was significant in the combined cemetery sample of 90 individuals (P < 0.019). When cemetery samples were tested separately, bilateral asymmetry was significant for the early Christian period sample (P < 0.001), but not for the late Christian period sample. There were no differences attributable to sex. Finally, we discuss why we conclude that environmental stress was favored over a biomechanic explanation as the cause for asymmetry. To the extent that our results support previous findings that early Christian period individuals were more affected by environmental stress than late Christian period individuals, it is reasonable to consider bilateral asymmetry in skeletal growth and maturation a good indicator of environmental stress. 相似文献

The relationship between advancing age in adults and patterns of cortical bone maintenance has been extensively documented for archaeological populations (Dewey, et al., 1969; Van Gerven et al., 1969; Perzigian, 1973). Most recently, this research has been expanded to include a more thorough consideration of the geometric properties of bone in relationship to adult age changes (Martin and Atkinsin, 1977; Ruff and Hayes, 1983). To date, however, few studies have documented subadult patterns of cortical bone maintenance in archaeological populations and none have incorporated the relationship between patterns of cortical bone loss and gain and the changing geometric properties of growing bone. Using a sample of 172 tibias from children excavated from the Medieval Christian site of Kulubnarti, located in Nubia's Batn el Hajar, the present research examines the relationship between percent cortical area, bone mineral content, and cross-sectional moments of inertia. Among these children, bone mineral content increases steadily from birth in spite of a reduction in percent cortical area during early and late childhood. It appears, therefore, that tissue quality of the bone is not adversely affected by the reduction. Furthermore, the reduction in percent cortical area in later childhood corresponds to a dramatic increase in bending strength measured by cross-sectional moments of inertia. Thus, whether this cortical reduction is due entirely or in part to either normal modeling or nutritional stress, the tissue and organ quality of the bone is not adversely affected. 相似文献

In a recent articleBocquet-Appel & Masset (1985) renew their criticism of paleodemography and criticizeVan Gerven & Armelagos' (1983) defense of paleodemographic methods. In the present analysis we respond toBocquet-Appel andMasset's criticisms ofVan Gerven andArmelagos and then address the question of whether paleodemographic methods are capable of producing plausible results based on what
is known about contemporary human populations. This is done by expanding the life tables previously analysed byVan Gerven and co-workers for the Medieval Christian site of Kulubnarti in Nubia'sBatn el Hajar. The expanded results are then compared to data obtained from contemporary human populations as well as interpreted in light
of Nubian culture history. 相似文献

The main aim of this study was to explore the usefulness of several types of vertebral pathology as activity markers in osteological populations. A total of 2165 vertebrae from 124 individuals were studied. They were derived from cemeteries in two villages: Villanueva de Soportilla (Burgos, north of Spain), with a Christian population, and La Torrecilla (Granada, south of Spain), inhabited by Muslims. Degenerative joint diseases, Schmorl's nodes, compression fractures and spondylolysis with spondylolisthesis were analysed in individuals and separate vertebral pieces. All pathological conditions, except compression fractures, were significantly more frequent in males than in females, reflecting more intensive labour conditions for males. They were significantly more frequent in males from Villanueva, a border population of peasant-soldiers, than in males from La Torrecilla. They were also significantly more frequent in females from Christian Villanueva than in those from Muslim La Torrecilla, where the women mainly worked at home. The benefits and limitations of the study of these vertebral pathologies are discussed. 相似文献

Cortical bone growth is analyzed for 174 children from a Medieval Christian population at Kulubnarti in the Batn el Hajar of Sudanese Nubia (550–1450 AD ). Using the tibia as a representative long bone, total subperiosteal area, cortical area, medullary area, and percent cortical area at midshaft were calculated. While growth in total and cortical areas, as well as in length, appear to be fairly well maintained, percent cortical area reveals unusual growth patterns which reflect excessive endosteal resorption. Compared to the relative reduction in bone mass which has been observed in malnourished living children, as well as with previously reported evidence for stress in the Kulubnarti population, the present data support an interpretation of nutritionally related stress and of no major diachronic dietary change. 相似文献

The Roman conquest of Britain was previously shown to have negatively impacted health, particularly for children, older adults, and men. We build upon this previous research by investigating the effect that status had on risks of mortality within the Roman Britain populations of Dorset. This study incorporates a sample of 291 individuals excavated from several cemeteries in the county of Dorset dating between the first to early fifth centuries AD. To assess the effect of status on risks of mortality, burial type was used as a proxy for status and modeled as a covariate affecting the Siler and Gompertz-Makeham models of mortality. The results of these analyses indicate that high-status individuals, particularly children, had a lower mortality risk compared to lower-status groups; and for those buried in urban cemeteries, higher-status individuals of all age-groups had a lower mortality risk. As with our previous study (Redfern and DeWitte: Am J Phys Anthropol 144 (2011) 269-285), we found that male mortality risk was higher than females, which we consider to reflect underlying sex-differences in immunity and disease response. 相似文献

Analysis of the pattern of dental disease in two Late Medieval populations from cemeteries excavated at archaeological sites in western Serbia was based on the study of tooth wear, ante-mortem tooth loss, caries, dental enamel hypoplasia, alveolar resorption, abscesses and calculus. The findings reported here show a high prevalence of attrition, alveolar resorption and caries, which suggest an abrasive diet and poor oral hygiene. 相似文献

以军都山墓地为代表的"玉皇庙文化"系中国北方青铜时代的一支具有鲜明地方特色的少数部族文化。本文对军都山墓地出土人骨牙齿标本作牙齿磨耗状况分析,试图为其饮食结构和社会经济形态的探讨提供线索。结果显示:军都山古代人群中,相同年龄组的男女两性牙齿磨耗差异不大;前部牙齿磨耗轻于后部臼齿,第一臼齿磨耗最重;臼齿磨耗样式大多呈现"正常平匀"式,臼齿磨耗角度大多较小,两者均随年龄而变化但没有显著的性别差异。经与其他样本组的对比认为军都山古代人群牙齿磨耗的特点可能与其社会经济农牧兼营的性质有关,推测动物性食物(肉食)可能在军都山古代人群主要饮食结构中占据重要比例,并包含有一定的农业经济成分。不同游牧人群牙齿磨耗程度差异较大,只有结合了磨耗形态及其他信息才有可能更切实地反映其饮食状况。 相似文献
