Northwest African Neolithic initiated by migrants from Iberia and Levant.

In northwestern Africa, lifestyle transitioned from foraging to food production around 7,400 years ago but what sparked that change remains unclear. Archaeological data support conflicting views: (1) that migrant European Neolithic farmers brought the new way of life to North Africa1-3 or (2) that local hunter-gatherers adopted technological innovations4,5. The latter view is also supported by archaeogenetic data6. Here we fill key chronological and archaeogenetic gaps for the Maghreb, from Epipalaeolithic to Middle Neolithic, by sequencing the genomes of nine individuals (to between 45.8- and 0.2-fold genome coverage). Notably, we trace 8,000 years of population continuity and isolation from the Upper Palaeolithic, via the Epipaleolithic, to some Maghrebi Neolithic farming groups. However, remains from the earliest Neolithic contexts showed mostly European Neolithic ancestry. We suggest that farming was introduced by European migrants and was then rapidly adopted by local groups. During the Middle Neolithic a new ancestry from the Levant appears in the Maghreb, coinciding with the arrival of pastoralism in the region, and all three ancestries blend together during the Late Neolithic. Our results show ancestry shifts in the Neolithization of northwestern Africa that probably mirrored a heterogeneous economic and cultural landscape, in a more multifaceted process than observed in other regions.

Maternal Lineages from 10-11th Century Commoner Cemeteries of the Carpathian Basin.

Nomadic groups of conquering Hungarians played a predominant role in Hungarian prehistory, but genetic data are available only from the immigrant elite strata. Most of the 10-11th century remains in the Carpathian Basin belong to common people, whose origin and relation to the immigrant elite have been widely debated. Mitogenome sequences were obtained from 202 individuals with next generation sequencing combined with hybridization capture. Median joining networks were used for phylogenetic analysis. The commoner population was compared to 87 ancient Eurasian populations with sequence-based (Fst) and haplogroup-based population genetic methods. The haplogroup composition of the commoner population markedly differs from that of the elite, and, in contrast to the elite, commoners cluster with European populations. Alongside this, detectable sub-haplogroup sharing indicates admixture between the elite and the commoners. The majority of the 10-11th century commoners most likely represent local populations of the Carpathian Basin, which admixed with the eastern immigrant groups (which included conquering Hungarians).

Genetic evidence suggests a sense of family, parity and conquest in the Xiongnu Iron Age nomads of Mongolia.

In an effort to characterize the people who composed the groups known as the Xiongnu, nuclear and whole mitochondrial DNA data were generated from the skeletal remains of 52 individuals excavated from the Tamir Ulaan Khoshuu (TUK) cemetery in Central Mongolia. This burial site, attributed to the Xiongnu period, was used from the first century BC to the first century AD. Kinship analyses were conducted using autosomal and Y-chromosomal DNA markers along with complete sequences of the mitochondrial genome. These analyses suggested close kin relationships between many individuals. Nineteen such individuals composed a large family spanning five generations. Within this family, we determined that a woman was of especially high status; this is a novel insight into the structure and hierarchy of societies from the Xiongnu period. Moreover, our findings confirmed that the Xiongnu had a strongly admixed mitochondrial and Y-chromosome gene pools and revealed a significant western component in the Xiongnu group studied. Using a fine-scale approach (haplotype instead of haplogroup-level information), we propose Scytho-Siberians as ancestors of the Xiongnu and Huns as their descendants.

[Living in the midst of miasmas: The social issue of Chile between 1880 and 1920]. / Viviendo entre miasmas: en torno a la cuestión social, Chile de 1880 a 1920.

INTRODUCTION: The social issue in Chile stems from an accumulation of social problems resulting from the migratory movements of the countryside-city and mining areas. The cities did not have the hygienic conditions necessary to receive migrants, which caused housing and health problems within the population. OBJECTIVE: To analyze the problems of housing, hygiene, and health in Chile between 1880-1920. METHOD: We conduct a qualitative, analytical, and interpretive study using primary sources for the categories of analysis around housing, hygiene, and health of the following cities in Chile: Santiago, Valparaíso, Concepción and Chillán. RESULTS: The economic modernization led to the development of public works in the main cities of Chile, which also experienced a demographic phenomenon known as field-city migration, with urban growth never before seen. In the cities, there were problems of housing, hygiene, and health for the popular urban sectors. CONCLUSION: The State passed laws to regulate the conditions of the conventillos and public spaces to mitigate diseases and vices of the population.

Ancient DNA reveals two paternal lineages C2a1a1b1a/F3830 and C2b1b/F845 in past nomadic peoples distributed on the Mongolian Plateau.

OBJECTIVES: Since the third century CE, a series of nomadic tribes have been active on the eastern part of the Mongolian Plateau. Characterizing the genetic compositions of past nomadic people is significant for research on the nomadic cultures of the Eurasian Steppe region. Ancient DNA analysis facilitates a deeper understanding of the relationship between historical and modern nomadic populations. MATERIALS AND METHODS: Whole-genome shotgun sequencing and capture sequencing of the nonrecombining region of the Y chromosome were performed for six ancient Hg C2/M217 individuals. The individuals were interred at six separate sites on the Mongolian Plateau and represent dates spanning the late Neolithic to Yuan Dynasty (~3,500-700 BP). RESULTS: After NRY capture sequencing, three of the six ancient samples were attributed to C2b1b/F845 and the other three ancient samples belonged to C2a1a1b1a/F3830. Analysis of whole-genome shotgun sequencing data shows that the ancient C2b1b/F845 individuals are closely related to She, Han and other East Asian populations, while the ancient C2a1a1b1a/F3830 individuals are more similar to modern Northeast Asian peoples, such as the Ulchi and Yakut. DISCUSSION: Hg C2/M217, widely distributed in the eastern part of the Eurasian continent, was discovered in the ancient Central Steppe and Baikal region. This study shows that there were two important subclades of Hg C2/M217 among the ancient nomadic peoples: C2a1a1b1a/F3830, which has made important genetic contributions to modern Mongolic- and Manchu-speaking populations, and C2b1b/F845, which probably originated in the farming populations of southern East Asia and made certain genetic contributions to past nomadic peoples on the Mongolian Plateau.

Migrant mortality differences in the 2000s in Belgium: interaction with gender and the role of socioeconomic position.

BACKGROUND: Belgium has a long history of migration. As the migrant population is ageing, it is crucial thoroughly to document their health. Many studies that have assessed this, observed a migrant mortality advantage. This study will extend the knowledge by probing into the interaction between migrant mortality and gender, and to assess the role of socioeconomic position indicators in this paradox. METHODS: Individually linked data of the 2001 Belgian Census, the National Register and death certificates for 2001-2011 were used. Migrant origin was based on both own and parents' origin roots. We included native Belgians and migrants from the largest migrant groups aged 25 to 65 years. Absolute and relative mortality differences by migrant origin were calculated for the most common causes of death. Moreover, the Poisson models were adjusted for educational attainment, home ownership and employment status. RESULTS: We observed a migrant mortality advantage for most causes of death and migrant groups, which was strongest among men. Adjusting for socioeconomic position generally increased the migrant mortality advantage, however with large differences by gender, migrant origin, socioeconomic position indicator and causes of death. CONCLUSIONS: Adjusting for socioeconomic position even accentuated the migrant mortality advantage although the impact varied by causes of death, migrant origin and gender. This highlights the importance of including multiple socioeconomic position indicators when studying mortality inequalities. Future studies should unravel morbidity patterns too since lower mortality not necessarily implies better health. The observed migrant mortality advantage suggests there is room for improvement. However, it is essential to organize preventative and curative healthcare that is equally accessible across social and cultural strata.

Mapping the origins of Imperial Roman workers (1st-4th century CE) at Vagnari, Southern Italy, using 87 Sr/86 Sr and δ18 O variability.

OBJECTIVES: We obtained the oxygen and strontium isotope composition of teeth from Roman period (1st to 4th century CE) inhabitants buried in the Vagnari cemetery (Southern Italy), and present the first strontium isotope variation map of the Italian peninsula using previously published data sets and new strontium data. We test the hypothesis that the Vagnari population was predominantly composed of local individuals, instead of migrants originating from abroad. MATERIALS AND METHODS: We analyzed the oxygen (18 O/16 O) and strontium (87 Sr/86 Sr) isotope composition of 43 teeth. We also report the 87 Sr/86 Sr composition of an additional 13 molars, 87 Sr/86 Sr values from fauna (n = 10), and soil (n = 5) samples local to the area around Vagnari. The 87 Sr/86 Sr variation map of Italy uses 87 Sr/86 Sr values obtained from previously published data sources from across Italy (n = 199). RESULTS: Converted tooth carbonate (δ18 ODW ) and 87 Sr/86 Sr data indicate that the majority of individuals buried at Vagnari were local to the region. ArcGIS bounded Inverse Distance Weighting (IDW) interpolation of the pan-Italian 87 Sr/86 Sr data set approximates the expected 87 Sr/86 Sr range of Italy's geological substratum, producing the first strontium map of the Italian peninsula. DISCUSSION: Results suggest that only 7% of individuals buried at Vagnari were born elsewhere and migrated to Vagnari, while the remaining individuals were either local to Vagnari (58%), or from the southern Italian peninsula (34%). Our results are consistent with the suggestion that Roman Imperial lower-class populations in southern Italy sustained their numbers through local reproduction measures, and not through large-scale immigration from outside the Italian peninsula.

The genetic prehistory of the Baltic Sea region.

While the series of events that shaped the transition between foraging societies and food producers are well described for Central and Southern Europe, genetic evidence from Northern Europe surrounding the Baltic Sea is still sparse. Here, we report genome-wide DNA data from 38 ancient North Europeans ranging from ~9500 to 2200 years before present. Our analysis provides genetic evidence that hunter-gatherers settled Scandinavia via two routes. We reveal that the first Scandinavian farmers derive their ancestry from Anatolia 1000 years earlier than previously demonstrated. The range of Mesolithic Western hunter-gatherers extended to the east of the Baltic Sea, where these populations persisted without gene-flow from Central European farmers during the Early and Middle Neolithic. The arrival of steppe pastoralists in the Late Neolithic introduced a major shift in economy and mediated the spread of a new ancestry associated with the Corded Ware Complex in Northern Europe.

[Psychosis: the importance of the migratory factor]. / Psychose : l'importance du facteur migratoire.

Migration can be considered as a major risk factor for the incidence of Psychotic disorders. It has observed in first and second-generation migrants. French studies provide concordant results. There is an increased risk in migrants from sub-saharian countries. Various hypotheses have been evoked as involvement of infectious agents, genetics and vitamin deficiency. Environmental factors seem to be of major important and more specifically discrimination. The role of protection factor as the social capital can be an interesting perspective to develop specific preventive strategies.

Ancestry and demography and descendants of Iron Age nomads of the Eurasian Steppe.

During the 1st millennium before the Common Era (BCE), nomadic tribes associated with the Iron Age Scythian culture spread over the Eurasian Steppe, covering a territory of more than 3,500 km in breadth. To understand the demographic processes behind the spread of the Scythian culture, we analysed genomic data from eight individuals and a mitochondrial dataset of 96 individuals originating in eastern and western parts of the Eurasian Steppe. Genomic inference reveals that Scythians in the east and the west of the steppe zone can best be described as a mixture of Yamnaya-related ancestry and an East Asian component. Demographic modelling suggests independent origins for eastern and western groups with ongoing gene-flow between them, plausibly explaining the striking uniformity of their material culture. We also find evidence that significant gene-flow from east to west Eurasia must have occurred early during the Iron Age.

Comparison of observed and expected levels of genetic diversity based on surname frequencies: An example from historical Massachusetts.

OBJECTIVES: The inverse of random inbreeding based on surname frequencies (1/Fr ) is an estimate of genetic diversity, and its expectation is a function of the number of migrants into a population. Observed and expected values of (1/Fr ) were compared to determine if observed diversity matches theoretical expectations under conditions of rapid demographic change using data from historical Massachusetts. MATERIALS AND METHODS: Data on migration and surnames were taken from 6,038 marriage records from the eighteenth and nineteenth centuries from five towns in north-central Massachusetts. Data for each town were broken down into a number of time cohorts defined by year of marriage, giving 33 samples based on town and year of marriage. The number of migrants (M) and the inverse of the random component of inbreeding (1/Fr ) were derived for each sample based on surname frequencies. RESULTS: There was no significant difference between observed and expected values of 1/Fr in samples where there were 100 or more migrants. However, 1/Fr was significantly higher in samples where M < 100, which is possibly due to these samples not having reached equilibrium, resulting in higher than expected values of 1/Fr . Regression of residual values of 1/Fr (observed-expected) on the number of years since settlement supports this interpretation. CONCLUSION: The number of migrants affects the level of genetic diversity inferred from surname frequencies, and the relationship between observed and expected measures depends on the number of migrants and the proximity of a given sample to an equilibrium state.

A Fragmentary Archive: Migratory Feelings in Early Anglo-Saxon Women's Letters.

The letters by Anglo-Saxon women in the Boniface correspondence are connected by cultural practices and emotions centered on the conversion mission that functioned to maintain connections between the Anglo-Saxon diaspora. A striking recurring focus of these letters is on loss and isolation, which connects them to the Old English elegies. Many of the letters describe the writers' traumatic experiences that result from the death or absence of kin. These are women who endured the trauma of being left behind when others migrated overseas or who, in traveling away from their homeland, found themselves isolated in an alien environment, displaced in time as well as space. This article offers an analysis of the letters, focusing on the queer temporalities they explore, the queer emotions they evoke, and the queer kinships that they forge. It argues that the women's letters represent fragments of an early queer archive of migratory feelings.

Aging: It's Interpersonal! Reflections From Two Life Course Migrants.

We start with the observation that aging gerontologists often engage in two distinct discourses on aging-one public and one private. This separation entails "othering," which reproduces agism and stigma. Based on personal experience, insight from colleagues and writers, and concepts from symbolic interaction perspectives, we argue that becoming old to some degree involves becoming a stranger. Before reaching old age, both of us have been in the position of strangers due to social experiences that left us "off the line" or "on the margins." Examples are crossing social borders related to nations, class structures, gender, race, health status, and generations. Our stories illustrate how aging is more than personal. It is interpersonal-shaped by social history, policies, interdependence in relationships, and the precariousness of old age. Such phenomena often show sharp contrasts in the interpersonal worlds and social experiences of women and men. Reflecting on our own journeys as life course migrants leaves us acutely aware of both the social problems and potential promises of aging.

Dynamics of Indian Ocean Slavery Revealed through Isotopic Data from the Colonial Era Cobern Street Burial Site, Cape Town, South Africa (1750-1827).

The Dutch East India Company (VOC) intended the Cape of Good Hope to be a refreshment stop for ships travelling between the Netherlands and its eastern colonies. The indigenous Khoisan, however, did not constitute an adequate workforce, therefore the VOC imported slaves from East Africa, Madagascar and Asia to expand the workforce. Cape Town became a cosmopolitan settlement with different categories of people, amongst them a non-European underclass that consisted of slaves, exiles, convicts and free-blacks. This study integrated new strontium isotope data with carbon and nitrogen isotope results from an 18th-19th century burial ground at Cobern Street, Cape Town, to identify non-European forced migrants to the Cape. The aim of the study was to elucidate individual mobility patterns, the age at which the forced migration took place and, if possible, geographical provenance. Using three proxies, 87Sr/86Sr, δ13Cdentine and the presence of dental modifications, a majority (54.5%) of the individuals were found to be born non-locally. In addition, the 87Sr/86Sr data suggested that the non-locally born men came from more diverse geographic origins than the migrant women. Possible provenances were suggested for two individuals. These results contribute to an improved understanding of the dynamics of slave trading in the Indian Ocean world.

Why was Infant Mortality so High in Eastern England in the mid Nineteenth Century?

This paper re-examines the high rates of infant mortality observed in rural areas of eastern England in the early years of civil registration. Infant mortality rates in some rural registration districts in the East Riding of Yorkshire, Cambridgeshire and Norfolk were higher than those in the mill towns of Lancashire. After describing the areas affected, this paper considers three potential explanations: environmental factors, poor-quality child care associated with the employment of women in agriculture, and the possibility that the high rates were the artefactual consequence of migrant women workers bringing their children to these areas. These explanations are then assessed using a range of evidence. In the absence of reliable cause of death data, recourse is had to three alternative approaches. The first involves the use of the exceptionally detailed tabulations of ages at death within the first year of life provided in the Registrar General's Annual Reports for the 1840s to assess whether the 'excess' infant deaths in rural areas of eastern England happened in the immediate post-natal period or later in the first year of life. Second, data on the seasonality of mortality in the 1840s are examined to see whether the zone of 'excess' infant mortality manifested a distinctive seasonal pattern. Finally, a regression approach is employed involving the addition of covariates to regression models. The conclusion is that no single factor was responsible for the 'excess' infant mortality, but a plausible account can be constructed which blends elements of all three of the potential explanations mentioned above with the specific historical context of these areas of eastern England.

[Migrants' masculinity and health. Taking care for one's health and coping with sickness of German migrants in the US in 19th and early 20th centuries]. / Männlichkeit und Gesundheit im Kontext von Migration. Praktiken der Gesundheitsfürsorge und KrankheitsbewäItigung deutscher Migranten in den USA im 19. Jahrhundert und frühen 20. Jahrhundert.

In 19. and early 20. centuries several million emigrants from German speaking countries entered the United States of America. How migrants coped with sickness, how they preserved their health and to which ressources and institutions of help they had access is yet an academic void. Using Ego-documents--letters, autobiographic texts and diaries--of near-illiterate men this paper will analyse 'healthy lifestyles' and practices of coping with sickness and contrast them with recent research findings in the field of 'mens' health'. Thereby the recent concept of ,male health-idiots' will be challenged in historical perspective.
