On the accuracy of estimating living stature from skeletal length in the grave and by linear regression

This study evaluates a method for obtaining stature estimates for populations represented by skeletal material, with individuals buried in a supine position. During the excavation of a Danish mediaeval cemetery, in situ skeletal length in the grave was measured from a point above the cranial point farthest from the body to the most distal point of the talus. The measurement was made with a folding rule placed on the sagittal midline of the skeleton, allowed to follow any curvature of the skeleton in situ. In the laboratory, stature was reconstructed anatomically, and this stature was regarded as an accurate estimate of living stature. Stature was also reconstructed from femur length by two linear regression procedures: 1) by sample and sex specific formulae, employing a leave‐one‐out approach, and 2) by sex wise formulae for Euro‐Americans from Trotter & Gleser (1952, American Journal of Physical Anthropology 10 : 463–514). Skeletal length in the grave and the two stature estimates based on linear regression were compared to anatomically reconstructed stature. Skeletal length in the grave estimated anatomically reconstructed stature with practically no bias (95% CI: −1.3–1.5 cm). Sample specific regression formulae estimated anatomically reconstructed stature also with no bias (95% CI: −1.2–1.1 cm). In contrast, statures calculated from Trotter & Gleser's regression formulae estimated anatomically reconstructed stature with a bias of about 4 cm (95% CI: 3.3–5.0 cm). Estimates of stature variance were biased for all three estimation procedures. However, for samples of adults, an adjusted variance estimate can be obtained by subtracting 8.7 cm² from the variance obtained from skeletal lengths in the grave. It is recommended to measure skeletal length in the grave whenever possible, and use this measurement for estimating statures for prehistoric and early historic populations.

New regression equations for stature estimation for medieval Scandinavians

Estimating stature from skeletal remains in an archaeological context requires appropriate methods that take into account possible temporal and spatial changes in body proportions. New regression equations—both least squares (LSQ) and reduced major axis (RMA) equations—were thus developed for estimating living stature from the long bone lengths of medieval inhabitants (N = 60) of Westerhus, Sweden. The living stature of these skeletal specimens was determined by using the anatomical method. Findings in this study reveal that LSQ regression equations systematically overestimate statures of short individuals and underestimate those of tall individuals, whereas the RMA equations—both combined sexes and sex‐specific equation—provide more accurate stature estimations for individuals of very different statures. The combined sexes RMA‐equations should be used for cases in which the sex is unknown because they provide more accurate stature estimations than sex‐specific equation with a wrong sex determination. These new equations are more appropriate than generally used regression equations for estimating statures of the medieval period Scandinavians. Copyright © 2009 John Wiley & Sons, Ltd.     

CHALLENGES IN APPROACHES TO SKELETAL STATURE ESTIMATION: AN EXAMPLE FROM PREHISTORIC EASTERN MISSISSIPPI AND WESTERN ALABAMA

Abstract

Although stature is used widely as a bioarchaeological health indicator, its determination and subsequent interpretation are not always straightforward. A study of 77 individuals from eight prehistoric populations from the Tennessee-Tombigbee Waterway illustrates this issue. Application of three common stature estimation formulae to five Middle/Late Woodland and four Mississippian groups strongly suggests that use of partial versus whole bone, choice of element, and stature estimation method can create disparate patterns in health interpretation, not only for the direction of differences but particularly regarding the degree of differences among groups.     

Stature estimation in a central Patagonian prehispanic population: development of new models considering specific body proportions

Stature estimation of individuals from extinct human populations is a classic topic in anthropology. The estimations, using regression formulae generated from different reference samples, display different results. This fact is related to inter‐populational differences in body proportions, which is a phenotypic trait mainly correlated with climatic parameters. The aim of this paper is to address the problem of stature estimation of an archaeological skeletal sample from Patagonia – a region for which there are no specific models available – using different methods and considering differences in body proportions between reference and target populations. The sample used in this analysis is composed of 35 Late Holocene adults of both sexes recovered in central Patagonia (Argentina). The stature of each individual was first reconstructed using the anatomical method [Fully G. 1956 . Une nouvelle me´thode de de´termination de la taille. Annales Medicine Legale 35 : 266–273], which has no assumptions on body proportions. The results were compared with estimations based on 32 different regression formulae [Trotter M, Gleser G. 1958. A re‐evaluation of estimation of stature based on measurements taken during life and the long bones after death. American Journal of Physical Anthropology 16 : 79–124. 10.1002/ajpa.1330160106] and three femur/stature ratios [Feldesman MR, Fountain RL. 1996. Race specificity and the femur/stature ratio. American Journal of Physical Anthropology 100 : 207–224. 10.1002/(SICI)1096‐8644(199606)]. The average reconstructed stature was 160.8 cm for females (95% confidence band = 155.6–166.2 cm), and 170.5 cm for males (95% confidence band = 168.8–172.2 cm). Most of the comparisons of the regression formulae and femur/stature ratios showed significant differences, which are explained by differences in body proportions between the Patagonian sample and the ones chosen as reference. Finally, a set of new equations was developed using simple regression techniques. It is suggested that whenever possible, population‐specific formulae should be used in archaeological studies. In any other situation, the choice of a reference population should be made by taking into account its geographic (latitudinal) provenance. Copyright © 2009 John Wiley & Sons, Ltd.     

The effect of population variation on the accuracy of sex estimates derived from basal occipital discriminant functions

Multiple discriminant functions that estimate sex from the dimensions of the basal occipital have been published. However, as there is limited exploration of basal dimension variation between groups, the accuracy of these functions when applied to archaeological material is unknown. This study compares basal dimensions between four known sex-at-death post-medieval European samples and explores how metric differences impact on the accuracy of sex assessment discriminant functions. Published data from St Bride’s, London (n = 146) and the Georges Olivier collection, Paris (n = 68) were compared with new data from the eighteenth to nineteenth century Dutch Middenbeemster sample (n = 74) and the early twentieth century Rainer sample, Romania (n = 282) using independent t tests. The Middenbeemster and Rainer data were substituted into six published discriminant functions derived from the St Bride’s and the Georges Olivier samples, and the results were compared to their known sex. Multiple statistically significant differences were found between the four groups. Of the six discriminant functions tested, five failed to reach the published accuracy and fell below chance. In addition, even where the samples were statistically comparable in means, trends for difference also impacted the accuracy of discriminant functions. Enough variation in basal occipital dimensions existed in the European groups to decrease the accuracy of sex estimation discriminant functions to unusable. Possible inter-observer error, varying genetic, socioeconomic, and geographical factors are likely causes of dimension variation. This research further highlights the dangers of using sex estimation discriminant functions on samples that differ to the original derivative population and demonstrates the need for more rigorous testing.     

Sex estimation using cervical dental measurements in an archaeological population from Iran

Sex estimation of skeletal remains is one of the major components of forensic identification of unknown individuals. Teeth are a potential source of information on sex and are often recovered in archaeological or forensic contexts due to their post-mortem longevity. Currently, there is limited data on dental sexual dimorphism of archaeological populations from Iran. This paper represents the first study to provide a dental sex estimation method for Iron Age populations. The current study was conducted on the skeletal remains of 143 adults from two Iron Age populations in close temporal and geographic proximity in the Solduz Valley (West Azerbaijan Province of Iran). Mesiodistal and buccolingual cervical measurements of 1334 maxillary and mandibular teeth were used to investigate the degree of sexual dimorphism in permanent dentition and to assess their applicability in sex estimation. Data was analysed using discriminant function analysis (SPSS 23), and posterior probabilities were calculated for all produced formulae. The results showed that incisors and canines were the most sexually dimorphic teeth, providing percentages of correct sex classification between 86.4 and 100 % depending on the measurement used. The combination of canines and other teeth improved significantly the level of correct sex classification. The highest percentages of sex classification were obtained by the combination of canines and incisors (100 %) and canines and molars (92.3 %). The present study provided the first reference standards for sex estimation using odontometric data in an Iranian archaeological population. Cervical measurements were found to be of value for sex assessment, and the method presented here can be a useful tool for establishing accurate demographic data from skeletal remains of the Iron Age from Iran.     

Frequency of Complete Cleft Sacra in a Native American Sample

The purpose of this paper is to contribute to the current understanding of the variability of complete sacral clefts in human populations by presenting new data on a large prehistoric and historic Native American skeletal sample (n = 1943). Results are examined by age, sex, time period, and regional distribution and compared with reported frequencies of complete sacral clefts in other modern, historic, and ancient populations. In all, 1.6% of the sample exhibited complete sacral clefts, including 2.1% of males and 1.1% of females. Although males exhibit a frequency twice as high as females, this difference is not statistically significant. However, within the Alaskan sample, the sex difference was significant (p = 0.002), with 3.4% of males and 0.5% of females exhibiting complete clefts; these differences may be related to mechanical influences during growth and development in males. Differences among age groups are not significant. Regional comparisons among Alaska, Eastern Woodlands, Great Basin/Northwest/California, Great Plains, and Southwest showed no significant differences overall, but Alaska (2.2%) and Great Plains (0.5%) do show a significant difference (p = 0.024). No significant differences were found between prehistoric, protohistoric, and historic/recent samples, suggesting a lack of a secular trend in frequency of complete sacral clefts in Native American populations. One individual exhibited an enlarged canal, which may be indicative of a more severe condition. Copyright © 2012 John Wiley & Sons, Ltd.     

Genetic sexing to determine the optimal discriminant functions for the analysis of archaeological remains from El Hierro (Canary Islands)

A correct sex assignment of a given bone or bone fragment is of paramount importance for the archaeologist, anthropologist and in forensic medicine. Discriminant functions, combining several anthropometric measurements obtained from individuals with known sex are useful tools for this purpose, but it is essential to know exactly the sex from which the measures are obtained. This is an easy task in modern populations, but it is problematic in ancient ones, since even when the entire skeleton is available, diagnosis of sex is not 100% accurate. Sexing by genetic methods by amplifying the first intron of the amelogenin gene constitutes a much more accurate method for sexing bones and may be the gold standard for further elaboration of discriminant functions which may serve for sexing new bones dug up in future excavations. With this aim we have genetically sexed 52 (out of 59) tibiae belonging to the prehispanic population of El Hierro, in the Canary Islands, identifying 18 women and 34 men, and then, performed discriminant functions combining several anthropometric variables. These functions show a high accuracy in sex diagnosis (94.2%; area under ROC curve = 0.954 with the best of the functions), so that they allow correct sexing of tibiae or tibiae fragments (only proximal third, distal third or midshaft). Thus, genetic sexing obviates the problem of finding an accurate gold standard for the elaboration of discriminant functions for ancient bones. This method could be applied to other populations of different antiquity and different ethnicity.     

Tracking Fish and Human Response to Earthquakes on the Northwest Coast of Washington State,USA: A Preliminary Study at Tse-whit-zen

Evidence of large earthquakes occurring along the Pacific Northwest Coast is reflected in coastal stratigraphy from Oregon to British Columbia, where there also exists an extensive archaeological record of Native American occupation. Tse-whit-zen, a large Native American village dating between ～2800 yrs BP and the historic era, located on the Olympic Peninsula of Washington State, was excavated with exceptionally fine stratigraphic control allowing for precise comparison of these natural and cultural records. Here we report on the ～10,000 fish remains from one 2 × 2 m excavation block; this assemblage spans the timing of one seismic event, allowing study of changes in relative taxonomic abundance through time that may coincide with earthquakes or other environmental changes. Results indicate a wide variety of fish taxa were used throughout the dated occupation. Comparisons of fish use before and after one earthquake event shows a decline in salmon (Oncorhynchus sp.) and an increase in herring (Clupea pallasii), shifts consistent with earthquake-related habitat loss. This serves as a pilot study for a large-scale collaborative project that is drawing on the range in animal types (invertebrates, mammals, birds, and fishes) to assess human response to gradual and abrupt environmental change at Tse-whit-zen.     

“…being weary,they had rebelled”: Pueblo subsistence and labor under Spanish colonialism

Native American responses to Spanish colonialism are explored through an analysis of multiple lines of evidence concerning subsistence practices, diet, and health in the Salinas Pueblo area of central New Mexico. Zooarchaeological and paleoethnobotanical data from three Pueblo villages that experienced different degrees of Spanish missionization are the focus of this study. In addition, human osteological data from one village provide important information on activity patterns and health. These data are used to document the kinds of changes that occurred in Pueblo labor patterns, food consumption, and health from the pre-colonial to colonial periods. Synthetic analyses document the development of some degree of inter-village specialization in large game hunting, hide processing, and corn farming, presumably in response to Spanish tribute levies in corn and antelope hides, and demands on Pueblo labor in other arenas. There also appears to be a degree of divergence in women’s and men’s lives in the colonial period. These southwestern data are then compared with similar information from the southeastern US to identify patterns of similarity and difference in Native American experiences of and strategies for dealing with Spanish colonization.     

Engendering New Netherland: Implications for Interpreting Early Colonial Societies

Here, we study the Algonquian and Iroquoian women who lived in settlements surrounding the Dutch colony of New Netherland, in today’s northeastern United States. We begin by examining their roles in the colony and find that their lives did not fall into the pattern of servitude, concubinage, culture-brokering, and intermarriage that many have seen as the fate of Native or African women in other colonial societies. Instead, these women were, by and large, independent agents and followed their own indigenous customs as they interacted with Europeans. We then go on to explore how this new revisionist view of their actions affects archaeological interpretations of their households and the households of the Europeans as well. We further point out how the role of Native women in New Netherland was influenced in part by the presence and absence of other groups of women—both European and African—there.     

Population-specific stature reconstruction for medieval Trondheim,Norway

Temporal changes in average stature are often used as a measure of a past population's adaptation, or lack of it. Traditionally, stature estimates have been calculated using formulae derived from limb proportions of cadavers. However, many authors have noted the problem of regional or population variation in body proportions of such reconstructed ratios. Before differences in stature can be attributed to environmental adaptation, ‘ethnic’ or population differences in limb ratios must be taken into account. The present paper calculates the stature of a medieval Norwegian skeletal sample using archaeological plan femur length and dry bone femur length. The author presents a variety of formulae and compares the stature derived from these calculations to the stature derived from archaeological plans. The Trondheim statures are then compared to stature reconstructions of other contemporary populations.     

A probable case of gigantism in a fifth Dynasty skeleton from the Western Cemetery at Giza,Egypt

Pituitary gigantism is a rare endocrine disorder caused by excess secretion of growth hormone during childhood. Individuals with this condition exhibit unusually tall stature due to prolonged growth as well as associated degenerative changes. Continued secretion of excess growth hormone during adulthood results in acromegaly, a related condition that results in bony overgrowth of the skull, hands and feet. The remains of a large adult male, probably in his late 20s or early 30s, from a Fifth Dynasty tomb (2494–2345 BC) were excavated in 2001 from Cemetery 2500 in the Western Cemetery at Giza, Egypt, as part of the Howard University Giza Cemetery Project. This individual exhibits characteristics of pituitary gigantism, including tall but normally‐proportioned stature, delayed epiphyseal union, a large sella turcica, advanced arthritis and a transepiphyseal fracture of the left femoral head. Additional pathological features, including osteopenia and thinness of the parietal bones, suggest that this individual may also have been hypogonadal. Craniometric comparisons with other ancient Egyptian groups as well as modern normal and acromegalic patients show some tendency toward acromegalic skull morphology. Differential diagnosis includes eunuchoid gigantism, Sotos syndrome, Beckwith‐Wiedemann syndrome, Marfan syndrome, homocystinuria, Weaver syndrome and Klinefelter syndrome. In conclusion, the pathological features associated with this skeleton are more consistent with pituitary gigantism than any of the other syndromes that result in skeletal overgrowth.

Merchandising and sanctity: the invasive cult of Padre Pio

In the final decades of the twentieth century, the Blessed Padre Pio da Pietrelcina (1887-1968) became a 'saint' of global stature. It is most exceptional for the cult of a saint to acquire such dimensions in so short a time. Further, this is the story not of someone with a modern profile of sanctity,but someone who on the contrary answers to the traditional model of sanctity, and whose cult is moreover characterized by an instrumental devotional repertoire. Despite this 'classic' model, his person and cult are extremely ambiguous. This article describes and analyses the processes which have brought and continue to bring this about, and the recent development of the cult in Italy. By these processes a controversial cult, often associated with anti-ecclesiastical devotional activities and of limited scope, has become one of the most important and irreproachable in Italy. In part through the personal support of Pope John Paul II, in about a decade Padre Pio has grown from a friar in a controversial fundamentalist context to an almost invulnerable national saint, who is beginning to become a part of the Italian identity. The power of his cult is so strong - a devotional avalanche - that it has sidelined other cults, and to an increasingly large degree defines the Italian sacred landscape. The Pio cult encroaches on other devotions, and moreover is becoming its own competitor: to an increasing degree Pio's central pilgrimage site at San Giovanni Rotondo is losing pilgrims to the secondary pilgrimage site at Pietrelcina and to the hundreds of chapels and local shrines that have sprung up the length of Italy.     

Body mass estimation in skeletal samples using the hybrid approach: the effect of population-specific variations and sexual dimorphism

Body mass is estimated from skeletal records with low accuracy, and it is expected that population-specific equations derived by a hybrid approach may help to reduce the error in body mass estimates. We used 204 individuals from five Central European Early Medieval sites to test the effect of population-specific femoral head breadth equations on the accuracy of body mass estimates. The baseline for living body mass was computed using the biiliac breadth and stature. We also analyzed the agreement of five general femoral head techniques that are used in body mass estimation (Elliott et al. (Archaeol Anthropol Sci 1–20, 2015b; Grine et al. (Am J Phys Anthropol 97:151–185, 1995); McHenry (Am J Phys Anthropol 87:407–431, 1992); Ruff et al. (Am J Phys Anthropol 148:601–617, 2012); Ruff et al. (Am J Phys Anthropol 86:397, 1991)). Our results support previous findings showing that body mass is predicted with lower accuracy than stature, even when population-specific equations are derived. However, the population-specific approach increases the agreement with the body mass estimated from the biiliac breadth and stature, particularly when sex-specific equations are used. Thus, our results advocate for the employment of sex-specific equations when possible and show that the possibility of deriving equation for each sex separately is the main advantage of the population-specific approach. The best agreement among the body mass techniques in the Central European Early Medieval samples was observed using the femoral head equations reported by Ruff et al. (Am J Phys Anthropol 148:601–617, 2012) and McHenry (Am J Phys Anthropol 87:407–431, 1992), whereas other studied equations provided lower agreement. The particularly low performance obtained using the technique reported by Elliott et al. (2015b) questioned the use of their equations to estimate body masses.     

Age‐at‐death assessment using the os pubis and the auricular surface of the ilium: a test on an identified Asian sample

This paper reviews the results of blind tests of two morphological methods of age‐at‐death estimation. These tests were performed on a known age‐at‐death and sex sample taken from a collection of a Thai population. The first technique is based on the age related changes of the pubic symphysis according to the Suchey‐Brooks system, and the other concerns the metamorphosis of the auricular surface of the ilium elaborated by Lovejoy and colleagues. This is the first time that these methods have been tested on skeletal material from Asia. The results indicate that, for both methods, bias and inaccuracy increase with age and true age tends to be underestimated. As a consequence, age‐at‐death assessment based on these two techniques should be avoided on Asian archaeological series or forensic cases. Copyright © 2004 John Wiley & Sons, Ltd.     

Trends in adult stature of peoples who inhabited the modern Portuguese territory from the Mesolithic to the late 20th century

This study documents long‐term changes in stature from the Mesolithic to the late 20^th century in the territory of modern Portugal. Data utilised originated from published sources and from a sample of the Lisbon identified skeletal collection, where long bone lengths were collected. Mean long bone lengths were obtained from 20 population samples and compiled into nine periods. Pooled long bone lengths for each period were then converted to stature estimates. Results show three major trends: (1) a slow increase in stature from prehistory to the Middle Ages; (2) a negative trend from the Middle Ages to the late 19^th century; and (3) a very rapid increase in mean stature during the second half of the 20^th century. The political and territorial stability of the Kingdom of Portugal may have contributed to the greater heights of the medieval Portuguese, compared with the Roman and Modern periods. The negative secular trend was rooted in poor and unsanitary living conditions and the spread of infectious disease, brought about by increased population growth and urbanisation. Although the end of the Middle Ages coincided with the age of discoveries, the population may not have benefited from the overall prosperity of this period. The 20^th century witnessed minor and slow changes in the health status of the Portuguese, but it was not until major improvements in social and economic conditions that were initiated in the 1960s, and further progress in the 1970s, that the Portuguese grew taller than ever before. Since the Middle Ages other European countries have experienced similar oscillations, but showed an earlier recovery in stature after the industrial period.

“‘I just don’t ever use that word’: investigating stakeholders’ understanding of heritage”

Abstract

Understanding the value of heritage sites for diverse stakeholders requires both paying attention to the fields of power in which the sites operate and applying methodologies that are open to user-defined paradigms of value. In the U.S., official discourse often frames the value of heritage sites associated the deep Native American past as archaeological sites, an interpretation that is consistent with settler colonial ideologies. This narrative generally obfuscates connections between the heritage of the sites and contemporary peoples, and it effaces the history of colonialism and dispossession. A study of stakeholder-defined heritage at two contested sites in the central Midwest revealed both congruencies and conflicts among diverse constituencies’ articulations of the sites’ value. At Mounds State Park a proposed dam and reservoir ‘Mounds Lake’ project would inundate a large portion of the site. At Strawtown Koteewi, Native American tribes have made repatriation claims under the federal Native American Graves Protection and Repatriation Act (NAGPRA).The study also problematised the term ‘cultural heritage’ as it is understood and used by the different constituencies, particularly for culturally and historically affiliated Native Americans. It also highlighted the positions of the constituencies within the broader fields of power implicated in these contested sites.     

Evaluations of sex assessment using weighted traits on incomplete skeletal remains

Several studies have presented a variety of sexually dimorphic traits on the skeleton offering possibilities to score these traits for sex determination. However, few have discussed how fragmentation of skeletons affects the reliability of the results, and how to assess sex attribution based on a variety of methods. In the present study sex was determined for 354 skeletons from the medieval Swedish town Sigtuna, using well‐recognized sexing techniques on the pelvis, skull and femur. The preservation of the skeletons varied markedly, thus affecting possibilities for sex assessments. An attempt was made to evaluate the result of the sex assessment when weighting of different traits with different scales was used. The resulting estimation for each individual was called total mean value A. In addition, a total mean value B that considers unobservable missing traits was estimated. It can be concluded that both weighting and fragmentation affect sex assessments of incomplete skeletons. Copyright © 2004 John Wiley & Sons, Ltd.     

Stature and frailty during the Black Death: the effect of stature on risks of epidemic mortality in London,A.D. 1348–1350

Recent research has shown that preexisting health condition affected an individual's risk of dying during the 14th-century Black Death. However, a previous study of the effect of adult stature on risk of mortality during the epidemic failed to find a relationship between the two; this result is perhaps surprising given the well-documented inverse association between stature and mortality in human populations. We suggest that the previous study used an analytical approach that was more complex than was necessary for an assessment of the effect of adult stature on risk of mortality. This study presents a reanalysis of data on adult stature and age-at-death during the Black Death in London, 1348–1350 AD. The results indicate that short stature increased risks of mortality during the medieval epidemic, consistent with previous work that revealed a negative effect of poor health on risk of mortality during the Black Death. However, the results from a normal, non-epidemic mortality comparison sample do not show an association between stature and risks of mortality among adults under conditions of normal mortality. Fisher's exact tests, used to determine whether individuals who were growing during the Great Famine of 1315–1322 were more likely to be of short stature than those who did not endure the famine, revealed no differences between the two groups, suggesting that the famine was not a source of variation in stature among those who died during the Black Death.
