Using ancient mtDNA to reconstruct the population history of northeastern North America

Mitochondrial DNA (mtDNA) was extracted and analyzed from the skeletal remains of 44 individuals, representing four prehistoric populations, and compared to that from two other prehistoric and several contemporary Native American populations to investigate biological relationships and demographic history in northeastern North America. The mtDNA haplogroup frequencies of ancient human remains from the Morse (Red Ocher tradition, 2,700 BP) and Orendorf (Mississippian tradition, 800 BP) sites from the Central Illinois River Valley, and the Great Western Park (Western Basin tradition, 800 BP) and Glacial Kame (2,900 BP) populations from southwestern Ontario, change over time while maintaining a regional continuity between localities. Haplotype patterns suggest that some ancestors of present day Native Americans in northeastern North America have been in that region for at least 3,000 years but have experienced extensive gene flow throughout time, resulting, at least in part, from a demic expansion of ancestors of modern Algonquian-speaking people. However, genetic drift has also been a significant force, and together with a major population crash after European contact, has altered haplogroup frequencies and caused the loss of many haplotypes.     

Pollen from archaeological layers and cultural landscape reconstruction: Case studies from the Bradano valley (Basilicata,southern Italy)

Abstract

The article aims at presenting some aspects of environmental reconstruction through pollen analysis from archaeological contexts. The anthropogenic pollen transport into archaeological sites is regarded as an interesting tool to improve knowledge on flora and vegetation in the area of influence of sites. The zoophilous plants can be found more easily than in the regional airborne pollen rain where anemophilous pollen is generally overrepresented. Moreover, pollen from archaeological contexts is mainly a result of the cultural landscape shaped by human activities. Two case studies from the Bradano Valley (Basilicata, southern Italy), rich in archaeological sites dating altogether from the Middle Bronze Age to the Medieval age, are reported. Difesa San Biagio and its surroundings is one of the biggest settlements of the area, settled in early times by Enotrians. Altojanni is an extended area mainly frequented in Hellenistic, Roman late Imperial and Medieval times. A very open landscape, and clear signs of plant exploitation and cultivation, breeding and settlements were present in the two sites. Though samples are disturbed and preservation problems are sometimes observed, the main characters of pollen spectra are recurrent. High percentages of Poaceae and Cichorioideae, together with coprophilous fungal spores, strongly suggest a long tradition of pastoral activities. These case study examples suggest that human activities would have produced a fairly xeric environment.     

Limitations imposed by wearing armour on Medieval soldiers' locomotor performance

In Medieval Europe, soldiers wore steel plate armour for protection during warfare. Armour design reflected a trade-off between protection and mobility it offered the wearer. By the fifteenth century, a typical suit of field armour weighed between 30 and 50 kg and was distributed over the entire body. How much wearing armour affected Medieval soldiers' locomotor energetics and biomechanics is unknown. We investigated the mechanics and the energetic cost of locomotion in armour, and determined the effects on physical performance. We found that the net cost of locomotion (C(met)) during armoured walking and running is much more energetically expensive than unloaded locomotion. C(met) for locomotion in armour was 2.1-2.3 times higher for walking, and 1.9 times higher for running when compared with C(met) for unloaded locomotion at the same speed. An important component of the increased energy use results from the extra force that must be generated to support the additional mass. However, the energetic cost of locomotion in armour was also much higher than equivalent trunk loading. This additional cost is mostly explained by the increased energy required to swing the limbs and impaired breathing. Our findings can predict age-associated decline in Medieval soldiers' physical performance, and have potential implications in understanding the outcomes of past European military battles.     

Diet and diversity at later medieval Fishergate: the isotopic evidence

We present the results of stable carbon and nitrogen isotope analysis of bone collagen for 155 individuals buried at the Later Medieval (13th to early 16th century AD) Gilbertine priory of St. Andrew, Fishergate in the city of York (UK). The data show significant variation in the consumption of marine foods between males and females as well as between individuals buried in different areas of the priory. Specifically, individuals from the crossing of the church and the cloister garth had consumed significantly less marine protein than those from other locations. Isotope data for four individuals diagnosed with diffuse idiopathic skeletal hyperostosis (DISH) are consistent with a diet rich in animal protein. We also observe that isotopic signals of individuals with perimortem sharp force trauma are unusual in the context of the Fishergate dataset. We discuss possible explanations for these patterns and suggest that there may have been a specialist hospital or a local tradition of burying victims of violent conflict at the priory. The results demonstrate how the integration of archaeological, osteological, and isotopic data can provide novel information about Medieval burial and society.     

Cranial variation in European populations: a spatial autocorrelation study at three time periods

This study reports on spatial variation of 10 cranial variables in European populations at 3 time periods. Means for these variables, based on 137, 108, and 183 samples from the Early Medieval, Late Medieval, and Recent periods, were subjected to one-dimensional and directional spatial autocorrelation analyses. Significant spatial structure was found for most variables. It becomes more pronounced as time progresses. The spatial patterns are not strongly clinal. Correlograms based on distances computed from all variables are monotonic only to 900, 1,650, and 1,350 km for the three periods. Regional patterns are seen for most variables and become more structured and significant with time. There is little similarity among the correlograms of the variables at any one period and virtually none among periods. Inferences about spatial structure of these populations, based on spatial autocorrelation analysis, suggest a pattern dominated by migration, followed by expansion and admixture rather than selection or chance fluctuations. The patterns of morphometric change seem to reflect the patterns of linguistic change in these areas.     

Migration to the Medieval Middle East with the Crusades

During the 12th and 13th centuries thousands of people moved from Europe to the Middle East to fight, undertake pilgrimage, or settle and make a new life. The aim of this research is to investigate two populations from the Crusader kingdom of Jerusalem, by determining who was born in Europe and who came from the Middle East. Oxygen and strontium stable isotope analyses were conducted on the enamel of teeth from skeletal remains excavated from Crusader contexts. Twenty individuals from the coastal city of Caesarea (10 high status and 10 low status), and two local Near Eastern Christian farmers from the village of Parvum Gerinum (Tel Jezreel) were analyzed as a control sample. Results were compared with known geographic values for oxygen and strontium isotopes. The population of the city of Caesarea appears to have been dominated by European‐born individuals (probably 19/20, but at least 13/20), with few locals. This was surprising as a much higher proportion of locals were expected. Both controls from the farming village of Parvum Gerinum had spent their childhood in the area of the village, which matches our understanding of limited mobility among poor Medieval farmers. This is the first time that stable isotope analysis has been applied to the study of the migration of peoples between Medieval Europe and the Middle East at the time of the crusades. In view of these findings, we must now rethink past estimations of population social structure in Levantine coastal Medieval cities during the Crusader period.

Charlemagne's Summit Canal: An Early Medieval Hydro-Engineering Project for Passing the Central European Watershed

The Central European Watershed divides the Rhine-Main catchment and the Danube catchment. In the Early Medieval period, when ships were important means of transportation, Charlemagne decided to link both catchments by the construction of a canal connecting the Schwabian Rezat and the Altmühl rivers. The artificial waterway would provide a continuous inland navigation route from the North Sea to the Black Sea. The shortcut is known as Fossa Carolina and represents one of the most important Early Medieval engineering achievements in Europe. Despite the important geostrategic relevance of the construction it is not clarified whether the canal was actually used as a navigation waterway. We present new geophysical data and in situ findings from the trench fills that prove for the first time a total length of the constructed Carolingian canal of at least 2300 metres. We have evidence for a conceptual width of the artificial water course between 5 and 6 metres and a water depth of at least 60 to 80 cm. This allows a crossing way passage of Carolingian cargo scows with a payload of several tons. There is strong evidence for clayey to silty layers in the trench fills which reveal suspension load limited stillwater deposition and, therefore, the evidence of former Carolingian and post-Carolingian ponds. These findings are strongly supported by numerous sapropel layers within the trench fills. Our results presented in this study indicate an extraordinarily advanced construction level of the known course of the canal. Here, the excavated levels of Carolingian trench bottoms were generally sufficient for the efficient construction of stepped ponds and prove a final concept for a summit canal. We have evidence for the artificial Carolingian dislocation of the watershed and assume a sophisticated Early Medieval hydrological engineering concept for supplying the summit of the canal with adequate water.     

An ethics of dwelling and a politics of world‐building: a critical response to ordinary ethics

In this essay I provide a critical reading of so‐called ‘ordinary ethics’ in order to disclose how it ultimately undoes two of the three major contributions of the anthropology of moralities and ethics: that is, ordinary ethics ultimately equates morality/ethics with all social activity and at the same time only accounts for morality/ethics in terms of the moral concepts already provided by the Western moral philosophical tradition. In the second part of this essay I provide an ethnographic example from anti‐drug war political activism that shows how a critical hermeneutics provides a theoretical‐analytical framework for the radical rethinking of both the moral tradition and the social and political worlds that mobilize the concepts and assumptions of this tradition.     

Phylogeography of a game species: the red-crested pochard (Netta rufina) and consequences for its management

Western European populations of red-crested pochard (Netta rufina) are characterized by low size and high fragmentation, which accentuate their sensitivity to hunting. Uncertainties regarding the demographic trends of these populations highlight the need for pertinent hunting regulations. This requires identification of the limits of the populations under exploitation, i.e. delimiting a management unit. We used the left domain of the mitochondrial control region and seven nuclear loci (four microsatellites and three introns) to assess the level of genetic structure and demographic independence between the fragmented Western European and the large Central Asian populations. The second objective was to investigate the colonization history of the Western European populations. This study demonstrated that the Western European populations of red-crested pochard constitute a separate demographic conservation unit relative to the Asian population as a result of very low female dispersal (mitochondrial DNA: PhiST = 0.152). A morphometric analysis further suggested that Central Asian and Western European specimens of both sexes originate from different pools of individuals. Male dispersal seems higher than female dispersal, as suggested by the lack of clear genetic structure for the nuclear markers at this continental scale. Genetic data, in conjunction with historical demographic data, indicate that the current Western European populations probably originate from a recent colonization from Central Asia. As numbers of red-crested pochards in Western Europe cannot be efficiently supplemented by immigration from the larger Asian populations, a management plan regulating the harvest in Western Europe is required.     

European medicinal mushrooms: Do they have potential for modern medicine? – An update

BackgroundThe application of mushrooms for health purposes has a long tradition and is very common in Asian countries. This trend is also becoming increasingly popular in the western hemisphere. However, mushrooms from European tradition are being treated in a restrained manner despite having significant potential as drugs or as sources of pure bioactive substances.Aim: The present review provides an overview of the most important mushrooms used in European ethnomedical traditions and explores their pharmacological potential and the challenges for the development of new drugs from these sources of natural products.Method: Mushroom species were selected based on information in old herbal books and dispensaries, uninterrupted use and scientific literature in the PubMed database up to June 2019.Results: Traditional experiences and modern studies have demonstrated that medical mushrooms used in European traditions have promising distinct pharmacological potential mediated through defined mechanisms (anti-tumour, anti-inflammatory, anti-oxidative and anti-bacterial). However, the number of modern chemical, biological and pharmacological studies remains relatively small, and some mushroom species have not been studied at all. Unfortunately, no valid clinical studies can be found. Unlike the case with herbal and fungal drugs from traditional Chinese medicine, we are far from comprehensively exploring this potential.Conclusions: Mushrooms from traditional European medicine have the potential to be used in modern medicine. Considerable research, interdisciplinary collaboration, involvement of the pharmaceutical industry, time and money are necessary to explore this potential not only in the form of dietary supplements but also in the form of approved drugs.     

Origin and genetic diversity of Western European populations of the potato cyst nematode (Globodera pallida) inferred from mitochondrial sequences and microsatellite loci

Native to South America, the potato cyst nematode Globodera pallida is one of the principal pests of Andean potato crops and is also an important global pest following its introduction to Europe, Africa, North America, Asia and Oceania. Building on earlier work showing a clear south to north phylogeographic pattern in Peruvian populations, we have been able to identify the origin of Western European populations with high accuracy. They are all derived from a single restricted area in the extreme south of Peru, located between the north shore of the Lake Titicaca and Cusco. Only four cytochrome b haplotypes are found in Western Europe, one of them being also found in some populations of this area of southern Peru. The allelic richness at seven microsatellite loci observed in the Western European populations, although only one-third of that observed in this part of southern Peru, is comparable to the allelic richness observed in the northern region of Peru. This result could be explained by the fact that most of the genetic variability observed at the scale of a field or even of a region is already observed at the scale of a single plant within a field. Thus, even introduction via a single infected potato plant could result in the relatively high genetic variability observed in Western Europe. This finding has important consequences for the control of this pest and the development of quarantine measures.     

Maxillary sinusitis in Medieval Chichester,England

Maxillary sinusitis is a common medical complaint, affecting more than 30 million people per year in the United States alone. Very little palaeopathological work on this disease has been carried out, probably because of the enclosed nature of the sinuses in intact skulls and the lack of a suitable method for examination. This study tested the hypothesis that maxillary sinusitis was more common in people with leprosy than in people without it in Medieval England. The prevalence of maxillary sinusitis by age and sex was recorded in 133 individuals, some diagnosed as being leprous, derived from a later Medieval (12th to 17th centuries AD) urban hospital population at Chichester, Sussex, England using both macroscopic and endoscopic methods of examination. Of the 133 individuals with one or both sinuses available for examination, 54.9% (73) had evidence of bone change within the sinuses. There was no difference in prevalence between those with leprosy and those without, although clinical studies suggest that over 50% of lepromatous leprous individuals may develop sinusitis. Comparison with another study on Medieval British sites with a 3.6% prevalence (3 of 83) indicates that the prevalence at Chichester is much greater. The problems with diagnosing sinusitis are addressed and reasons behind the high frequency in this study are discussed. Aetiological factors predisposing to maxillary sinusitis are considered with reference to possible environmental conditions prevailing in the later Medieval period in Britain. © 1995 Wiley-Liss, Inc.     

European common frog (Rana temporaria) recolonized Switzerland from multiple glacial refugia in northern Italy via trans‐ and circum‐Alpine routes

The high mountain ranges of Western Europe had a profound effect on the biotic recolonization of Europe from glacial refugia. The Alps present a particularly interesting case because they form an absolute barrier to dispersal for most taxa, obstructing recolonization from multiple refugia in northern Italy. Here, we investigate the effect of the European Alps on the phylogeographic history of the European common frog Rana temporaria. Based on partial cytochrome b and COXI sequences from Switzerland, we find two mitochondrial lineages roughly north and south of the Alpine ridge, with contact zones between them in eastern and western Switzerland. The northern haplogroup falls within the previously identified Western European haplogroup, while the southern haplogroup is unique to Switzerland. We find that the lineages diverged ~110 kya, at approximately the onset of the last glacial glaciation; this indicates that they are from different glacial refugia. Phylogenetic analyses suggest that the northern and southern haplogroups colonized Switzerland via trans‐ and circum‐Alpine routes from at least two separate refugia in northern Italy. Our results illustrate how a complex recolonization history of the central European Alps can arise from the semi‐permeable barrier created by high mountains.     

A newly discovered founder population: the Roma/Gypsies

The Gypsies (a misnomer, derived from an early legend about Egyptian origins) defy the conventional definition of a population: they have no nation-state, speak different languages, belong to many religions and comprise a mosaic of socially and culturally divergent groups separated by strict rules of endogamy. Referred to as "the invisible minority", the Gypsies have for centuries been ignored by Western medicine, and their genetic heritage has only recently attracted attention. Common origins from a small group of ancestors characterise the 8-10 million European Gypsies as an unusual trans-national founder population, whose exodus from India played the role of a profound demographic bottleneck. Social and economic pressures within Europe led to gradual fragmentation, generating multiple genetically differentiated subisolates. The string of population bottlenecks and founder effects have shaped a unique genetic profile, whose potential for genetic research can be met only by study designs that acknowledge cultural tradition and self-identity.     

Comparative study of the prevalence of maxillary sinusitis in later Medieval urban and rural populations in Northern England

Six hundred sixty-three Medieval individuals from Wharram Percy, a rural settlement in the Yorkshire Wolds, and 1,042 individuals from St. Helen-on-the-Walls, a poor parish in the Medieval city of York, were examined in order to test the hypothesis that maxillary sinusitis would be more prevalent in an urban population due to social and environmental conditions characteristic of an industrialized settlement. The results showed that the individuals from St. Helen-on-the-Walls, living in the urban environment, had a greater prevalence of maxillary sinusitis than the rural population; 39% (106) of the individuals from Wharram Percy had evidence of sinusitis compared to 55% (134) of the individuals from St. Helen-on-the-Walls. It is suggested that this pattern may be attributed to occupation and industrial air pollution in the Medieval city of York. © 1995 Wiley-Liss, Inc.     

Human Rights and Japanese Bioethics

The main contentions of this paper are twofold. First, there is a more than century-old Japanese tradition of human rights based on a fusion of Western concepts of natural rights and a radical reinterpretation of Confucianism, the major proponent of which was the Japanese thinker Nakae Chomin. Secondly, this tradition, although a minority view, is crucial for remedying the serious defects in the present Japanese medical system.
In the latter half of the nineteenth century, Nakae Chomin sought to reinterpret Chinese tradition, especially Confucianism, by injecting the concepts of popular sovereignty and democratic equality, drawn from Western sources. The resulting view maintained the Confucian commitment to a moral nexus for society, but replaced hierarchy with egalitarianism.
The pressing need for such an approach to patients' rights in present-day Japan is illustrated by two recent cases: the photographing and commercial exploitation of patients' genitals without serious response by authorities, and the attempt by physicians to manipulate the time of death and, possibly, to improperly pressure family members in order to transplant organs from the brain-dead victim of a criminal assault.
Such problems stem from hierarchy and paternalism, which seem to be a legacy of the rapid, state-sponsored introduction of Western medicine in the mid-nineteenth century, and in particular from the government's adoption of and support for German military medicine as a model for Japan.

Cross-cultural perspectives on music and musicality

Musical behaviours are universal across human populations and, at the same time, highly diverse in their structures, roles and cultural interpretations. Although laboratory studies of isolated listeners and music-makers have yielded important insights into sensorimotor and cognitive skills and their neural underpinnings, they have revealed little about the broader significance of music for individuals, peer groups and communities. This review presents a sampling of musical forms and coordinated musical activity across cultures, with the aim of highlighting key similarities and differences. The focus is on scholarly and everyday ideas about music—what it is and where it originates—as well the antiquity of music and the contribution of musical behaviour to ritual activity, social organization, caregiving and group cohesion. Synchronous arousal, action synchrony and imitative behaviours are among the means by which music facilitates social bonding. The commonalities and differences in musical forms and functions across cultures suggest new directions for ethnomusicology, music cognition and neuroscience, and a pivot away from the predominant scientific focus on instrumental music in the Western European tradition.     

On the cultural unity of Europe and a European dictionary project

There is a cultural unity of Europe, notwithstanding the Reformation. This unity must be 'consciously' recognized, in order to develop the concept of European togetherness. The paper will examine the common roots of the European vocabulary, submitting the project for the compilation of some dictionaries, to which European colleagues will be called to contribute. European languages must be studied no more as 'national' languages, but in the context of the European tradition, emphasizing what they have in common, and not what separates them. Hence the necessity of compiling dictionaries on a new basis, of which early, summary indications are given.
