A Paleogenomic Reconstruction of the Deep Population History of the Andes

There are many unanswered questions about the population history of the Central and South Central Andes, particularly regarding the impact of large-scale societies, such as the Moche, Wari, Tiwanaku, and Inca. We assembled genome-wide data on 89 individuals dating from ∼9,000-500 years ago (BP), with a particular focus on the period of the rise and fall of state societies. Today's genetic structure began to develop by 5,800 BP, followed by bi-directional gene flow between the North and South Highlands, and between the Highlands and Coast. We detect minimal admixture among neighboring groups between ∼2,000-500 BP, although we do detect cosmopolitanism (people of diverse ancestries living side-by-side) in the heartlands of the Tiwanaku and Inca polities. We also highlight cases of long-range mobility connecting the Andes to Argentina and the Northwest Andes to the Amazon Basin. VIDEO ABSTRACT.

Ultra close-range digital photogrammetry in skeletal anthropology: A systematic review

Background

Ultra close-range digital photogrammetry (UCR-DP) is emerging as a robust technique for 3D model generation and represents a convenient and low-cost solution for rapid data acquisition in virtual anthropology.

Objectives

This systematic review aims to analyse applications, technical implementation, and performance of UCR-DP in skeletal anthropology.

Methods

The PRISMA guidelines were applied to the study. The bibliographic search was performed on March 1^st, 2019 using Scopus and MEDLINE databases to retrieve peer-reviewed studies accessible in English full-text. The authors worked independently to select the articles meeting inclusion criteria, upon discussion. Studies underwent to quantitative and qualitative syntheses.

Results

Twenty-six studies were selected. The majority appeared in 2016 or after and were focused on methodological aspects; the applications mainly dealt with the documentation of skeletal findings and the identification or comparison of anatomical features and trauma. Most authors used commercial software packages, and an offline approach. Research is still quite heterogeneous concerning methods, terminology and quality of results, and proper validation is still lacking.

Conclusions

UCR-DP has great potential in skeletal anthropology, with many significant advantages: versatility in terms of application range and technical implementation, scalability, and photorealistic restitution. Validation of the technique, and the application of the cloud-based approach, with its reduced requirements relating to hardware, labour, time, and cost, could further facilitate the sharing of large collections for research and communication purposes.

Anthropogenic or non-anthropogenic particulate matter: Which one is more dangerous and how to differentiate between the effects?

The authors have observed that the function linking health outcomes with exposure to particulate-matter (PM) follows a biphasic pattern. It peaks around levels of PM10≤100 μg/m3, then weakens and rises again at PM10 levels in the range of hundreds. This could be due to a different nature of PM, the first peak reflecting a stronger anthropogenic and the second - weaker non-anthropogenic particles' effect. The current analysis is focused at the biphasic pattern on the association between PM levels with BG and asthma exacerbations. Pollutants were assessed by local monitoring stations and a satellitebased model. Local weekends/holidays were used to define nonanthropogenic levels of pollutants featured by lower Nitrogen Dioxide, the proxy for anthropogeneity. The association of PM₁₀ with health outcomes within 24-48h lag was explored using spline functions of generalized additive models. Analysis of 546,420 BG tests (43,569 subjects) showed an almost linear association of PM₁₀ with asthma with BG during the days with anthropogenic activity and no trend on other days. Analysis of asthmatic exacerbations within 1576 children showed no heterogeneity in association with PM₁₀ by anthropogeneity levels, possibly indicating a mechanical impact on alveolar as the main trigger for exacerbations rather than PM₁₀ chemical composition.

What animals do not do or fail to find: A novel observational approach for studying cognition in the wild

To understand how our brain evolved and what it is for, we are in urgent need of knowledge about the cognitive skills of a large variety of animal species and individuals, and their relationships to rapidly disappearing social and ecological conditions. But how do we obtain this knowledge? Studying cognition in the wild is a challenge. Field researchers (and their study subjects) face many factors that can easily interfere with their variables of interest. Although field studies of cognition present unique challenges, they are still invaluable for understanding the evolutionary drivers of cognition. In this review, I discuss the advantages and urgency of field-based studies on animal cognition and introduce a novel observational approach for field research that is guided by three questions: (a) what do animals fail to find?, (b) what do they not do?, and (c) what do they only do when certain conditions are met? My goal is to provide guidance to future field researchers examining primate cognition.

"The dead shall be raised": Multidisciplinary analysis of human skeletons reveals complexity in 19th century immigrant socioeconomic history and identity in New Haven, Connecticut

In July 2011, renovations to Yale-New Haven Hospital inadvertently exposed the cemetery of Christ Church, New Haven, Connecticut’s first Catholic cemetery. While this cemetery was active between 1833 and 1851, both the church and its cemetery disappeared from public records, making the discovery serendipitous. Four relatively well-preserved adult skeletons were recovered with few artifacts. All four individuals show indicators of manual labor, health and disease stressors, and dental health issues. Two show indicators of trauma, with the possibility of judicial hanging in one individual. Musculoskeletal markings are consistent with physical stress, and two individuals have arthritic indicators of repetitive movement/specialized activities. Radiographic analyses show osteopenia, healed trauma, and other pathologies in several individuals. Dental calculus analysis did not identify any tuberculosis indicators, despite osteological markers. Isotopic analyses of teeth indicate that all four were likely recent immigrants to the Northeastern United States. Nuclear and mitochondrial DNA were recovered from three individuals, and these analyses identified ancestry, hair/eye color, and relatedness. Genetic and isotopic results upended our initial ancestry assessment based on burial context alone. These individuals provide biocultural evidence of New Haven’s Industrial Revolution and the plasticity of ethnic and religious identity in the immigrant experience. Their recovery and the multifaceted analyses described here illuminate a previously undescribed part of the city’s rich history. The collective expertise of biological, geochemical, archaeological, and historical researchers interprets socioeconomic and cultural identity better than any one could alone. Our combined efforts changed our initial assumptions of a poor urban Catholic cemetery’s membership, and provide a template for future discoveries and analyses.

Reconstruction of ancestral footfalls in South Asia using genomic data

Due to its unique geographical position, juxtaposed in the middle of south-central Asia, east Asia and Southeast Asia, the South Asian Region (SAS) has repeatedly come into contact with people from adjacent regions throughout history and prehistory. The antiquity of the populations and the intricate history of admixture have shaped SAS as one of the most genetically diverse regions in the world. In this article we review our current understanding of the peopling and populations structure of SAS. We do not attempt to be exhaustive but summarize the salient conclusions that have been reached using genetic data and evaluate their robustness. We also identify the unanswered questions and suggest possible approaches that may lead to their answers.

Methodological issues in the Indo-European debate

The Indo-European debate has been going on for a century and a half. Initially confined to linguistics, race-based anthropology and comparative mythology, it soon extended to archaeology, especially with the discovery of the Harappan civilization, and peripheral disciplines such as agriculture, archaeometallurgy or archaeoastronomy. The latest entrant in the field, archaeogenetics, is currently all but claiming that it has finally laid to rest the whole issue of a hypothetical migration of Indo-Aryan speakers to the Indian subcontinent in the second millennium BCE. This paper questions the finality of this claim by pointing to inherent limitations, methodological issues and occasional biases in current studies as well as in the interpretation of archaeological evidence.

Peopling of India: Ancient DNA perspectives

To reconstruct and explain patterns of genetic diversity of modern humans, understanding their past and present genetic profile is crucial. While genomes of contemporary people can provide information about present day population structure, analysis of ancient genomes may provide unprecedented insights about the past demographic events that have shaped the contemporary gene pool. Population genetics has recently witnessed an explosion in studies on ancient human population histories, primarily from Europe and America. South Asia has no representation in the ancient genomics literature, despite the wealth of archaeological richness in the form of human skeletal remains that exist in collections all over the country. Representing one-fifth of present day humanity calls for understanding the demographic history of south Asia not merely as a prerequisite but as an urgent need to understand its genetic variations on a global scale. Although the overall picture is taking form, new archaeological and genetic information from the region has started to reveal a more complex scenario of ancient human migrations and admixtures than was ever known before. In this article, we discuss a meaningful insight on the current status of ancient DNA (aDNA) research in India. We have also summarized a few but important aDNA studies, which have been successfully carried out in India. Furthermore, we have highlighted the potential opportunity of aDNA research in the Indian subcontinent.

Historic migration to South Asia in the last two millennia: A case of Jewish and Parsi populations

The South Asian populations have a mosaic of ancestries likely due to the interactions of long-term populations of the landmass and those of East andWest Eurasia. Apart from prehistoric dispersals, there are some known population movements to India. In this study,we focussed on the migration of Jewish and Parsi populations on temporal and spatial scales. The existence of Jewish and Parsi communities in India are recorded since ancient times. However, due to the lack of high-resolution genetic data, their origin and affiliation with other Indian and non-Indian populations remains shrouded in legends. Earlier genetic studies on populations of Indian Jews have found evidence for a minor shared ancestry of Indian Jews with Middle Eastern (Jews) populations, whereas for Parsis, the Iranian link was proposed. Recently, in our high-resolution study, we were able to quantify the admixture dynamics of these groups, which has suggested a male-biased admixture. Here, we added the newly available ancient samples and revisited the interplay of genes and cultures. Thus, in this study we reconstructed a broad genetic profile of Indian Jews and Parsis to paint a fine-grained picture of these ethnic groups.

Development of typological classification and its relationship to microdifferentiation in ethnic India

The history of the racial classification of the people of India can be looked at in three temporal phases: (1) at the national level, the initial studies of racial classification attempted along with the Census of India; (2) at the regional level, studies by anthropologists and statisticians following systematic sampling and statistical procedures were conducted after the initial national-level studies and (3) population-specific studies in different regions across the country including micro-evolutionary studies of individual populations followed the regional studies. Initially the racial classification was part of the Census survey conducted by British anthropologists in some parts of the country among castes and tribes and was based on a few physical traits. This was followed by a systematic anthropometric survey in particulars regions (e.g., UP, Bengal, etc.) by anthropologists and statisticians. This was followed by population specific micro-evolutionary studies across different regions by numerous anthropologists investigating the role of selection, drift, migration and admixture and other population structure variables among endogamous castes and tribes.

Can artificially deforming skulls cause "defects of intelligence"? The observations of a positivist anthropologist on an artificially deformed skull discovered in Naples

We discuss a particular case of an artificially deformed skull discovered in Naples in 1892 and published in the Italian Journal of Natural Sciences by the anthropologist Abele De Blasio. To comprehend the observations of the researcher about the "defects of intelligence" caused by the artificial deformation of the skull, we will also analyze other articles in which De Blasio presented the deformed skulls of ancient Peruvian mummies.

Hunter-gatherer studies and human evolution: A very selective review

The century long publication of this journal overlapped major changes in the sciences it covers. We have been eyewitnesses to vast changes during the final third of the last century and beginning of this one, momentous enough to fundamentally alter our work separately and collectively. One (NBJ) from animal ethology, another from western North American archaeology (JOC), and a third (KH) from cultural anthropology came to longtime collaboration as evolutionary ecologists with shared focus on studying modern hunter-gatherers to guide hypotheses about human evolution. Our findings have radically revised hypotheses each of us took for granted when we began. Our (provisional) conclusions are not the consensus among hunter-gatherer specialists; but grateful that personal reflections are invited, we aim to explain how and why we continue to bet on them.

How should we diagnose disease in palaeopathology? Some epistemological considerations

This paper analyses some of the epistemological frameworks that underpin diagnosis in palaeopathology. Currently, the dominant approach is comparative: relationships between skeletal lesions and disease in a reference group in which there is independent evidence of the diseases present in individuals are used to identify disease in unknown archaeological skeletons on the basis of the lesions present. This is essentially a reference sample - target sample approach, analogous to that used to develop methodology in other areas of biological anthropology (e.g. age estimation in palaeodemography). As well as considerable strengths, this approach also has significant weaknesses. Many of these arise from the nature of the reference material (mainly pathology museum and other skeletal collections, and published collations of medical imaging data) used to develop diagnostic criteria. There may also be a tendency toward over-emphasis on pattern-matching between reference and target material, and an under-emphasis on developing our understanding of the biology of bone lesions. Despite its shortcomings, the comparative approach is likely to remain the foundation of most palaeopathological work, but we should increasingly augment it with other diagnostic approaches, especially those grounded in the pathophysiology of bony responses to disease.

Stochasticity in cultural evolution: a revolution yet to happen

Over the last 40 years or so, there has been an explosion of cultural evolution research in anthropology and archaeology. In each discipline, cultural evolutionists investigate how interactions between individuals translate into group level patterns, with the aim of explaining the diachronic dynamics and diversity of cultural traits. However, while much attention has been given to deterministic processes (e.g. cultural transmission biases), we contend that current evolutionary accounts of cultural change are limited because they do not adopt a systematic stochastic approach (i.e. accounting for the role of chance). First, we show that, in contrast with the intense debates in ecology and population genetics, the importance of stochasticity in evolutionary processes has generated little discussion in the sciences of cultural evolution to date. Second, we speculate on the reasons, both ideological and methodological, why that should be so. Third, we highlight the inadequacy of genetically-inspired stochastic models in the context of cultural evolution modelling, and ask which fundamental stochastic processes might be more relevant to take up. We conclude that the field of cultural evolution would benefit from a stochastic revolution. For that to occur, stochastic models ought to be developed specifically for cultural data and not through a copy-pasting of neutral models from population genetics or ecology.

The "in-between writer": Howard Stein, PhD, professor emeritus, psycho-analytic anthropologist, poet, educator, transdisciplinary scholar

This commentary reflects the professional life story of a prolific and well-published poet, Howard Stein. An anthropologist by training, Howard's poetry is well known and well respected by family physicians. It is within family medicine that Howard found his professional home, and in his 45-plus-year career he has shared the value of "patient story"; the value of the doctor-patient relationship; and the art of listening deeply to self, colleagues, and patients. This commentary offers a tribute to Howard's professional life and his contributions to family and narrative medicine. (PsycINFO Database Record

CT Scan of Thirteen Natural Mummies Dating Back to the XVI-XVIII Centuries: An Emerging Tool to Investigate Living Conditions and Diseases in History

Objectives

To correlate the radiologic findings detected with computed tomography scan with anthropological data in 13 naturally mummified bodies discovered during works of recovery of an ancient church in a crypt in Roccapelago, in the Italian Apennines.

Methods

From a group of about sixty not-intentionally mummified bodies, thirteen were selected to be investigated with volumetric computed tomography (CT). Once CT scan was performed, axial images were processed to gather MPR and Volume Rendering reconstructions. Elaborations of these images provided anthropometric measurements and a non-invasive analysis of the residual anatomical structures. For each body the grade of preservation and the eventual pathological changes were recorded. Furthermore, in order to identify nutritional and occupational markers, radiologic signs of bone tropism and degenerative changes were analysed and graded.

Results

Mummies included seven females and six males, with an estimated age ranging from 20 to 60 years. The first relevant finding identified was a general low grade of preservation, due to the lack of anatomic tissues different from bones, tendons and dehydrated skin. The low grade of preservation was related to the natural process of mummification. Analysing bone degenerative changes on CT scan, the majority of the bodies had significant occupational markers consisting of arthritis in the spine, lower limbs and shoulders even in young age. Few were the pathological findings identified. Among these, the most relevant included a severe bilateral congenital hip dysplasia and a wide osteolytic lesion involving left orbit and petrous bone that was likely the cause of death.

Conclusions

Although the low grade of preservation of these mummies, the multidisciplinary approach of anthropologists and radiologists allowed several important advances in knowledge for the epidemiology of Roccapelago. First of all, a profile of living conditions was delineated. It included occupational and nutritional conditions. Moreover, identification of some causes of death and, most importantly the definition of general living conditions.

A Phylogenetic Comparative Study of Bantu Kinship Terminology Finds Limited Support for Its Co-Evolution with Social Organisation

The classification of kin into structured groups is a diverse phenomenon which is ubiquitous in human culture. For populations which are organized into large agropastoral groupings of sedentary residence but not governed within the context of a centralised state, such as our study sample of 83 historical Bantu-speaking groups of sub-Saharan Africa, cultural kinship norms guide all aspects of everyday life and social organization. Such rules operate in part through the use of differing terminological referential systems of familial organization. Although the cross-cultural study of kinship terminology was foundational in Anthropology, few modern studies have made use of statistical advances to further our sparse understanding of the structuring and diversification of terminological systems of kinship over time. In this study we use Bayesian Markov Chain Monte Carlo methods of phylogenetic comparison to investigate the evolution of Bantu kinship terminology and reconstruct the ancestral state and diversification of cousin terminology in this family of sub-Saharan ethnolinguistic groups. Using a phylogenetic tree of Bantu languages, we then test the prominent hypothesis that structured variation in systems of cousin terminology has co-evolved alongside adaptive change in patterns of descent organization, as well as rules of residence. We find limited support for this hypothesis, and argue that the shaping of systems of kinship terminology is a multifactorial process, concluding with possible avenues of future research.

[Surprisingly old skeleton found at Bornheim-Uedorf (Rhein-Sieg-Kreis)--Research results in forensic medicine, anthropology and archaeology]

On April 15th 2014, human skeletal remains were found during digging activities for constructing a new building at Bornheim-Uedorf (Rhein-Sieg-Kreis) near the river Rhine (about 20 meters) in a pit measuring 10 by 10 meters and having a depth of about 150 cm. The skeletal remains were preserved quite well considering the fact that they were located so near to the Rhine, although several skeletal parts were missing. The preserved skeletal remains comprised some skull fragments (including two ear bones of the right side), right scapula, both humeri, left ulna, left radius, left metacarpal bone 2, right metacarpal bones 1, 3 and 4, rib fragments, three thoracic vertebrae, all lumbar vertebrae, one sacral vertebra, pelvis fragments, left femur, proximal part of the left tibial diaphysis, right tibia and diaphysis of both fibulae. The anthropological analysis revealed that the skeletal remains belonged to a 20-to-30-year-old presumably male individual with a body height of about 163 to 173 cm (depending on the formula used for body height estimation). Evidence of intense physical activity and traumatological findings could not be detected on the preserved bones. Periosteal reactions on the bone surface caused by nonspecific bacterial infection were found on the right humerus close to the elbow and on both tibiae, especially the left one. Besides the skeletal remains, metal fragments were recovered--among them an arrowhead, which was typologically classified as an early medieval finding (6th to 7th century). Radiocarbon dating of a bone sample revealed an age of 1561 ± 19 a BP corresponding to a calibrated age of 436 to 540 AD (1 sigma). So, the archaeological classification of the recovered skeleton into the early medieval period was verified. Amongst the human remains, there was also a metatarsal bone of cattle with cut marks. The animal bone as well as the metal fragments indicated that the find was part of an early medieval burial with typical grave goods.

Digital data collection in paleoanthropology

Understanding patterns of human evolution across space and time requires synthesizing data collected by independent research teams, and this effort is part of a larger trend to develop cyber infrastructure and e-science initiatives. At present, paleoanthropology cannot easily answer basic questions about the total number of fossils and artifacts that have been discovered, or exactly how those items were collected. In this paper, we examine the methodological challenges to data integration, with the hope that mitigating the technical obstacles will further promote data sharing. At a minimum, data integration efforts must document what data exist and how the data were collected (discovery), after which we can begin standardizing data collection practices with the aim of achieving combined analyses (synthesis). This paper outlines a digital data collection system for paleoanthropology. We review the relevant data management principles for a general audience and supplement this with technical details drawn from over 15 years of paleontological and archeological field experience in Africa and Europe. The system outlined here emphasizes free open-source software (FOSS) solutions that work on multiple computer platforms; it builds on recent advances in open-source geospatial software and mobile computing.

Community centrality and social science research

Community centrality is a growing requirement of social science. The field's research practices are increasingly expected to conform to prescribed relationships with the people studied. Expectations about community centrality influence scholarly activities. These expectations can pressure social scientists to adhere to models of community involvement that are immediate and that include community-based co-investigators, advisory boards, and liaisons. In this context, disregarding community centrality can be interpreted as failure. This paper considers evolving norms about the centrality of community in social science. It problematises community inclusion and discusses concerns about the impact of community centrality on incremental theory development, academic integrity, freedom of speech, and the value of liberal versus communitarian knowledge. Through the application of a constructivist approach, this paper argues that social science in which community is omitted or on the periphery is not failed science, because not all social science requires a community base to make a genuine and valuable contribution. The utility of community centrality is not necessarily universal across all social science pursuits. The practices of knowing within social science disciplines may be difficult to transfer to a community. These practices of knowing require degrees of specialisation and interest that not all communities may want or have.

Study of dental occlusion in ancient human remains: a methodological approach

The anthropological dental and maxillary study in human skeletal remains usually refers to alterations or conditions of the oral cavity. These alterations could have repercussions on life style, dietary habits and diseases. In this particular context, dental occlusion is not often analyzed due to the fragmented condition of the remains, and especially due to the lack of methodology adapted to study ancient remains. The aim of this study is to propose an anthropological method based on clinical dental practice. In the method presented in this work, odontological parameters such as overjet, overbite, and Angle's Classification of Malocclusion, are evaluated.

Molecular paleoparasitological hybridization approach as effective tool for diagnosing human intestinal parasites from scarce archaeological remains

Paleoparasitology is the science that uses parasitological techniques for diagnosing parasitic diseases in the past. Advances in molecular biology brought new insights into this field allowing the study of archaeological material. However, due to technical limitations a proper diagnosis and confirmation of the presence of parasites is not always possible, especially in scarce and degraded archaeological remains. In this study, we developed a Molecular Paleoparasitological Hybridization (MPH) approach using ancient DNA (aDNA) hybridization to confirm and complement paleoparasitological diagnosis. Eight molecular targets from four helminth parasites were included: Ascaris sp., Trichuris trichiura, Enterobius vermicularis, and Strongyloides stercoralis. The MPH analysis using 18th century human remains from Praça XV cemetery (CPXV), Rio de Janeiro, Brazil, revealed for the first time the presence E. vermicularis aDNA (50%) in archaeological sites of Brazil. Besides, the results confirmed T. trichiura and Ascaris sp. infections. The prevalence of infection by Ascaris sp. and E. vermicularis increased considerably when MPH was applied. However, a lower aDNA detection of T. trichiura (40%) was observed when compared to the diagnosis by paleoparasitological analysis (70%). Therefore, based on these data, we suggest a combination of Paleoparasitological and MPH approaches to verify the real panorama of intestinal parasite infection in human archeological samples.

Top 10 research questions related to body composition

An understanding of body composition is crucial to understanding human health, disease, and function. Research in body composition has focused on the development of assessment methods, description of normal changes in body composition with growth and development and aging, and the changes that occur in body composition in response to challenges ranging from illness to planned interventions. Each focus is significant, and in a sense, they are interdependent, because technological advances allow more sophisticated questions to be addressed, which in turn drives the development of better methods. Significant advances have been made in each area, although perhaps surprisingly basic questions remain. For example, growth trajectories are often estimated from cross-sectional data, given the resources needed for long-term observational studies, and thus, longitudinal descriptive data are still needed. Along with advances in laboratory methods, development of field methods remains relevant for screening and clinical practice. Despite recognition of wide interindividual differences in intervention response, average outcomes continue to be emphasized. With technological advances, it is now possible to examine genetic along with nongenetic factors that underlie changes in body composition, and these techniques need to be applied in long-term, well-controlled trials. In this article, we review 10 key questions in related areas in which research is needed to continue to advance the field.

At the crossroads of anthropology and epidemiology: current research in cultural psychiatry in the UK

Cultural psychiatry research in the UK comprises a broad range of diverse methodologies, academic disciplines, and subject areas. Methodologies range from epidemiological to anthropological/ethnographic to health services research; mixed methods research is becoming increasingly popular, as are public health and health promotional topics. After briefly outlining the history of cultural psychiatry in the UK we will discuss contemporary research. Prominent themes include: the epidemiology of schizophrenia among Africans/Afro-Caribbeans, migration and mental health, racism and mental health, cultural identity, pathways to care, explanatory models of mental illness, cultural competence, and the subjective experiences of healthcare provision among specific ethnic groups such as Bangladeshis and Pakistanis. Another strand of research that is attracting increasing academic attention focuses upon the relationship between religion, spirituality, and mental health, in particular, the phenomenology of religious experience and its mental health ramifications, as well as recent work examining the complex links between theology and psychiatry. The paper ends by appraising the contributions of British cultural psychiatrists to the discipline of cultural psychiatry and suggesting promising areas for future research.

Generational changes in the growth of children from Maribor and Slovenia

Among the numerous factors which influence a child's growth and development are also factors of changeable socio-economic environment and life style. Our aim was to evaluate these changes and contribute to preventive measures and evaluation of a child's growth in pediatric practice. Therefore, we decided to estimate the state of body growth in two generations of children from Maribor at five and six years of age of both gender, establish secular changes and define standards. On a representative sample (gender and age) of 1461 children from Maribor measured in 1996 and a sample of 608 children from Maribor, measured in 1966, 28 body features were studied and compared in each population unit. Variables were statistically and epidemiologically assessed and results were controlled by a test. The following anthropometric differences were significant: in 5-year old boys the measures in the 1996 generation are statistically higher than in 1966 - foot length, head length, upper arm skinfold, subscapular skinfold, arm length, arm diameter, upper thigh skinfold, stature (length), suprailiac skinfold, and body weight. Decreased measures are: abdomen circumference, knee circumference, sitting height, elbow circumference, biacromial diameter, and face heigth. In 6-year old boys additional features have increased in comparison with the year 1966: sternal height, tight circumference, hip width, chest circumference; following measures have decreased: face height, head circumference. In 5-year old girls: increased measures in comparison with the generation from 1966 are: lower leg length, head length, ankle circumference, upper arm skinfold, body weight, billiac diameter, body height, subscapular skinfold, chest circumference, hip circumference, sternal height, suprailiac skinfold, decreased measures are: head circumference, elbow circumference, face circumference, shoulder with, sitting height. In 6-year old girls additional measures are increased: wrist circumference, arm length and chest circumference. Changing trends show an increased tendency towards decrease or increase of most body measurements. In everyday practice the most commonly used measurements are: body mass, head circumference, body length in babies and body height in pre-school children. Our measurements proved, with a p-value of 0.001, that measurements of children in 1966, also shown in diagrams, are significantly different from measurements in 1996. In the second part of this paper we present a part of the anthropometric measurement study carried out for the standardization of the DENVER II developmental screening test. There were 1596 healthy Slovene children between zero and six and half years of age included into the observation. Children come from Maribor, Koper, Velenje and Ljubljana. We used the Cameron's measurement and statistical method. Diagrams were made for following body measures: body mass, body height, head circumference, upper arm circumference, thigh circumference and body mass index. A comparative analysis with the Euro-Growth study showed that our results correspond with the European standards. Therefore, our results are suggested to be applied in everyday pediatric practice.

Film and television in Croatia today: production, new technologies and the relationship with visual anthropology

This paper seeks to explain some of the most important recent production and technological changes that have affected the relationship between television and film, especially in Croatia, from the aspect of the development of visual anthropology. In the production segment, special attention was given to the role of Croatian television stations in the production of movies, "splitting" the movies into mini-series, interrupting movies with commercial breaks, and to television movies turned into feature films. This paper tries to perceive and define the structure of methodical processes of visual anthropology (reactive process). The development of photographic and film technology and the events which led to the rapid development of visual culture also point to the inseparable duality of observing visual anthropology within reactive and proactive processes, which are indirectly closely related to the technical aspects of these processes. Defining the technical aspect of visual anthropology as such "service" necessarily interferes with the author's approach in the domain of the script and direction related procedures during pre-production, on the field and during post-production of the movie. The author's approach is important because in dependence on it, the desired spectrum of information "output", susceptible to subsequent scientific analysis, is achieved. Lastly, another important segment is the "distributive-technological process" because, regardless of the approach to the anthropologically relevant phenomenon which is being dealt with in an audio-visual piece of work, it is essential that the work be presented and viewed adequately.

Island of Dugi otok through history: ethnohistorical and demographic processes on the island of Dug otok, Croatia

The present paper aims at describing the most relevant background data on geomorphological, economic, ethnohistoric and demographic features of the island of Dugi otok. As an introduction to future holistic anthropological research on the island, it seeks to identify both internal and external impulses of change and/or continuity of the island population structure within a wider socio-cultural and historical context. As migrations and its demographic fluctuations, we also investigate Dugi otok 's most important economic branch - fishery. The purpose of this paper is to provide insight into these Dugi otok population's activities. For better understanding of migrations, we include amigration matrix of Dugi otok.

Predictors of collective guilt after the violent conflict

After a violent conflict many post-conflict communities remain ethnically divided and normalization of the inter-group relations is hindered not only by in-group norms and interpretation of past events, but also by collective guilt. Although collective guilt has proved to be an important indicator of post-conflict social repair, more research is needed to define its predictors. This study, conducted in an ethnically divided community, confirmed that collective guilt acceptance and collective guilt assignment in our sample are typical for the post-conflict pattern of intergroup relations--people readily assign guilt to the outgroup but are unwilling to accept the guilt of their in-group. This suggests that the process of community social reconstruction has not considerably progressed. Our findings also suggest that the two aspects of collective guilt--assignment and acceptance--are predicted by similar sets of variables. Both collective guilt assignment and collective guilt acceptance are influenced by identification with in-group which influence is fully or partially mediated with the justification of the in-group's wrongdoings. This indicates that in the post-conflict setting relationship towards the in-group may be more important for experiencing collective guilt than the relationship towards the out-group. Relationship towards out-group, although not crucial, also plays a role in experiencing collective guilt. Specifically, both affect towards and cognitions about out-group members predict collective guilt assignment (with cognition being stronger predictor than positive affect), whereas only (absence of) positive affect predicts acceptance of collective guilt and the cognitive aspect is not predictive.

Beautiful fruits taste good: the aesthetic influences of fruit preferences in humans

Although diversity of fruit/seed colouration has received a great amount of attention since Darwin, little is known about its role in eating preferences in humans. We have determined that humans prefer certain fruits/seeds over others and that their willingness to eat them has been significantly influenced by the perceived aesthetic of the presented fruits and seeds. Participants were unable to discriminate between edible and poisonous fruits/ seeds based on their colour. Females rated all the groups of fruits/seeds as more attractive than males with this supporting the role of females in picking fruit in our evolutionary past. Red fruits were rated as more attractive than green or brown fruits. The results support the idea that fruit/seed colouration plays an important role in plant--disperser coevolution and that aesthetic judgment in humans have been shaped by natural selection.

A pilot study comparing furosemide and hydrochlorothiazide in patients with hypertension and stage 4 or 5 chronic kidney disease

Furosemide is the diuretic of choice for the treatment of hypertension in chronic kidney disease but the adaptative changes in the distal nephron may decrease its efficacy. Hydrochlorothiazide is not believed to be efficient in this setting. In a randomized, double-blind, cross-over trial, 23 patients with hypertension and stage 4 or 5 chronic kidney disease received long-acting furosemide (60 mg) and hydrochlorothiazide (25 mg) for 3 months and then both diuretics for 3 months. Sodium and chloride fractional excretions were measured after 3 months of each diuretic and then after their association. A trend towards an increase in the fractional excretion of sodium and chloride was observed with furosemide and hydrochlorothiazide (P=not significant). The association of the two diuretics increased the fractional excretions of sodium and chloride from 3.4±1.8 to 4.9±2.8 and from 3.8±2.0 to 6.0±3.1, respectively (P<.05). Furosemide and hydrochlorothiazide decreased mean blood pressure by the same extent. The association of the two diuretics was more efficient on blood pressure. There were no differences between furosemide and hydrochlorothiazide with respect to natriuresis and blood pressure control in patients with hypertension and chronic kidney disease.

Darkness’s descent on the American Anthropological Association. A cautionary tale

In September 2000, the self-styled “anthropological journalist” Patrick Tierney began to make public his work claiming that the Yanomamö people of South America had been actively—indeed brutally—harmed by the sociobiological anthropologist Napoleon Chagnon and the geneticist-physician James Neel. Following a florid summary of Tierney’s claims by the anthropologists Terence Turner and Leslie Sponsel, the American Anthropological Association (AAA) saw fit to take Tierney’s claims seriously by conducting a major investigation into the matter. This paper focuses on the AAA’s problematic actions in this case but also provides previously unpublished information on Tierney’s falsehoods. The work presented is based on a year of research by a historian of medicine and science. The author intends the work to function as a cautionary tale to scholarly associations, which have the challenging duty of protecting scholarship and scholars from baseless and sensationalistic charges in the era of the Internet and twenty-four-hour news cycles.

Biochemical characterization of major bone-matrix proteins using nanoscale-size bone samples and proteomics methodology

There is growing evidence supporting the need for a broad scale investigation of the proteins and protein modifications in the organic matrix of bone and the use of these measures to predict fragility fractures. However, limitations in sample availability and high heterogeneity of bone tissue cause unique experimental and/or diagnostic problems. We addressed these by an innovative combination of laser capture microscopy with our newly developed liquid chromatography separation methods, followed by gel electrophoresis and mass spectrometry analysis. Our strategy allows in-depth analysis of very limited amounts of bone material, and thus, can be important to medical sciences, biology, forensic, anthropology, and archaeology. The developed strategy permitted unprecedented biochemical analyses of bone-matrix proteins, including collagen modifications, using nearly nanoscale amounts of exceptionally homogenous bone tissue. Dissection of fully mineralized bone-tissue at such degree of homogeneity has not been achieved before. Application of our strategy established that: (1) collagen in older interstitial bone contains higher levels of an advanced glycation end product pentosidine then younger osteonal tissue, an observation contrary to the published data; (2) the levels of two enzymatic crosslinks (pyridinoline and deoxypiridinoline) were higher in osteonal than interstitial tissue and agreed with data reported by others; (3) younger osteonal bone has higher amount of osteopontin and osteocalcin then older interstitial bone and this has not been shown before. Taken together, these data show that the level of fluorescent crosslinks in collagen and the amount of two major noncollagenous bone matrix proteins differ at the level of osteonal and interstitial tissue. We propose that this may have important implications for bone remodeling processes and bone microdamage formation.

Testing for divergent transmission histories among cultural characters: a study using Bayesian phylogenetic methods and Iranian tribal textile data

BACKGROUND

Archaeologists and anthropologists have long recognized that different cultural complexes may have distinct descent histories, but they have lacked analytical techniques capable of easily identifying such incongruence. Here, we show how bayesian phylogenetic analysis can be used to identify incongruent cultural histories. We employ the approach to investigate Iranian tribal textile traditions.

METHODS

We used bayes factor comparisons in a phylogenetic framework to test two models of cultural evolution: the hierarchically integrated system hypothesis and the multiple coherent units hypothesis. In the hierarchically integrated system hypothesis, a core tradition of characters evolves through descent with modification and characters peripheral to the core are exchanged among contemporaneous populations. In the multiple coherent units hypothesis, a core tradition does not exist. Rather, there are several cultural units consisting of sets of characters that have different histories of descent.

RESULTS

For the Iranian textiles, the bayesian phylogenetic analyses supported the multiple coherent units hypothesis over the hierarchically integrated system hypothesis. Our analyses suggest that pile-weave designs represent a distinct cultural unit that has a different phylogenetic history compared to other textile characters.

CONCLUSIONS

The results from the Iranian textiles are consistent with the available ethnographic evidence, which suggests that the commercial rug market has influenced pile-rug designs but not the techniques or designs incorporated in the other textiles produced by the tribes. We anticipate that bayesian phylogenetic tests for inferring cultural units will be of great value for researchers interested in studying the evolution of cultural traits including language, behavior, and material culture.

Anthropological neurology: symptoms and their meanings according to Joseph Prick (1909-1978)

This article describes the life and work of the Dutch neurologist Joseph Prick (1909-1978) and his idea of an anthropological neurology. According to Prick, neurological symptoms should not only be explained from an underlying physico-chemical substrate but also be regarded as meaningful. We present an outline of the historical and philosophical context of his ideas with a focus on the theory of the human body by the French philosopher Maurice Merleau-Ponty (1908-1961) and the concept of anthropology-based medicine developed by Frederik Buytendijk (1887-1974). We give an overview of anthropological neurology as a clinical practice and finally we discuss the value of Prick's approach for clinical neurology today.

Lucy's flat feet: the relationship between the ankle and rearfoot arching in early hominins

BACKGROUND

In the Plio-Pleistocene, the hominin foot evolved from a grasping appendage to a stiff, propulsive lever. Central to this transition was the development of the longitudinal arch, a structure that helps store elastic energy and stiffen the foot during bipedal locomotion. Direct evidence for arch evolution, however, has been somewhat elusive given the failure of soft-tissue to fossilize. Paleoanthropologists have relied on footprints and bony correlates of arch development, though little consensus has emerged as to when the arch evolved.

METHODOLOGY/PRINCIPAL FINDINGS

Here, we present evidence from radiographs of modern humans (n = 261) that the set of the distal tibia in the sagittal plane, henceforth referred to as the tibial arch angle, is related to rearfoot arching. Non-human primates have a posteriorly directed tibial arch angle, while most humans have an anteriorly directed tibial arch angle. Those humans with a posteriorly directed tibial arch angle (8%) have significantly lower talocalcaneal and talar declination angles, both measures of an asymptomatic flatfoot. Application of these results to the hominin fossil record reveals that a well developed rearfoot arch had evolved in Australopithecus afarensis. However, as in humans today, Australopithecus populations exhibited individual variation in foot morphology and arch development, and "Lucy" (A.L. 288-1), a 3.18 Myr-old female Australopithecus, likely possessed asymptomatic flat feet. Additional distal tibiae from the Plio-Pleistocene show variation in tibial arch angles, including two early Homo tibiae that also have slightly posteriorly directed tibial arch angles.

CONCLUSIONS/SIGNIFICANCE

This study finds that the rearfoot arch was present in the genus Australopithecus. However, the female Australopithecus afarensis "Lucy" has an ankle morphology consistent with non-pathological flat-footedness. This study suggests that, as in humans today, there was variation in arch development in Plio-Pleistocene hominins.

[Culture and nursing care, from a biomedical to an anthropological approach]

Nursing training and practice have for a long time taken a biomedical approach to disease and the body, which fails to guarantee treatment which takes into account the differences of each patient. With transcultural healthcare theories and practices, partly inspired by anthropology, patients are explicitly considered as subjects whose experiences are a result of cultural, ethnic and social dimensions.

Toward a theory of deaf ethnos: deafnicity -- D/deaf (Homaemon - Homoglosson - Homothreskon)

Should ethnicity be used to interpret relations between the Deaf community and the hearing people? Recent scholarship questioning the merits of Deaf ethnicity suggests a need to reexamine the use of ethnicity when describing Deaf identity and culture. This article provides an overview of key contributions to race and ethnicity discourse in the 20th century, identifies epistemological and ontological errors to avoid, suggests adherence to the classical Greek concept of ethnos as an alternative to ethnie, and argues for the continuing significance of Deaf ethnicity. Specifically, I propose that Deaf ethnicity is a triadic relational nexus that approximates communities of origin, language, and religion. This is expressed as Deafnicity approximately D/deaf (Hómaemon * Homóglosson * Homóthreskon). Deafnicity offers a promising alternative for examining relations between Deaf and hearing communities, exploring variance between nationalized Deaf communities, and expanding our understanding of audism.

Molecular anthropology in the genomic era

Molecular Anthropology is a relatively young field of research. In fact, less than 50 years have passed since the symposium "Classification and Human Evolution" (1962, Burg Wartenstein, Austria), where the term was formally introduced by Emil Zuckerkandl. In this time, Molecular Anthropology has developed both methodologically and theoretically and extended its applications, so covering key aspects of human evolution such as the reconstruction of the history of human populations and peopling processes, the characterization of DNA in extinct humans and the role of adaptive processes in shaping the genetic diversity of our species. In the current scientific panorama, molecular anthropologists have to face a double challenge. As members of the anthropological community, we are strongly committed to the integration of biological findings and other lines of evidence (e.g. linguistic and archaeological), while keeping in line with methodological innovations which are moving the approach from the genetic to the genomic level. In this framework, the meeting "DNA Polymorphisms in Human Populations: Molecular Anthropology in the Genomic Era" (Rome, December 3-5, 2009) offered an opportunity for discussion among scholars from different disciplines, while paying attention to the impact of recent methodological innovations. Here we present an overview of the meeting and discuss perspectives and prospects of Molecular Anthropology in the genomic era.

Fieldwork: man in the system of nature and priority of natural laws in human life

Fieldwork is a branch of inseparable unity of natural and humanitarian sciences; it is aimed at the cultural origin of humanity on the maximum level of its variety. Practically all natural sciences have some space determined by ethnic conscience in nature cognition: ethnodemography, ethnobotany, ethnozoology, etc. Fieldwork guides the research of human culture from the laws of nature. This kind of knowledge is useful to balance human relations with nature and avoid conflicts. Peoples should exchange their wisdom in the dialogue with nature to be more safe. Fieldwork understood as traditional culture only, explaining the variety of ethnoses on our earth, is just the narrow and diachronic level of this branch of knowledge. The cosmological knowledge, where fantasy and not exhausted in its cognition understanding the world of nature are mixed, forms the source of fieldwork and in many respects explains the direction of knowledge: the man finds himself under the open sky, he is the child of nature. Then as time went on there appeared a gradual transition--first nature was creating the man, then by and by he began turning to answer nature by his activity. Nowadays the man is actively creating nature. There are two levels of fieldwork: the ancient one which deals with the origin of ethnoses and the modern one which explores how contemporary life is determined by ethnic specific traits. Fieldwork is the core of multidisciplinary situation in man's knowledge. It is related to such humanitarian sciences: semiotics, culturology, sociology, history, philosophy, literature, linguistics. In the cycle of natural sciences fieldwork stands close to anthropology, geography, biology, demography. Fieldwork as a science has the two main levels--the "sophy" level and the logos "level". The first one discovers wisdom of human life, the second one is aimed at logical structuring of knowledge, here proceed various classifications of peoples.
