The genetic legacy of the expansion of Bantu-speaking peoples in Africa.

The expansion of people speaking Bantu languages is the most dramatic demographic event in Late Holocene Africa and fundamentally reshaped the linguistic, cultural and biological landscape of the continent1-7. With a comprehensive genomic dataset, including newly generated data of modern-day and ancient DNA from previously unsampled regions in Africa, we contribute insights into this expansion that started 6,000-4,000 years ago in western Africa. We genotyped 1,763 participants, including 1,526 Bantu speakers from 147 populations across 14 African countries, and generated whole-genome sequences from 12 Late Iron Age individuals8. We show that genetic diversity amongst Bantu-speaking populations declines with distance from western Africa, with current-day Zambia and the Democratic Republic of Congo as possible crossroads of interaction. Using spatially explicit methods9 and correlating genetic, linguistic and geographical data, we provide cross-disciplinary support for a serial-founder migration model. We further show that Bantu speakers received significant gene flow from local groups in regions they expanded into. Our genetic dataset provides an exhaustive modern-day African comparative dataset for ancient DNA studies10 and will be important to a wide range of disciplines from science and humanities, as well as to the medical sector studying human genetic variation and health in African and African-descendant populations.

The Migration of Lynch Victims' Families, 1880-1930.

We examine the relationship between the lynching of African Americans in the southern United States and subsequent county out-migration of the victims' surviving family members. Using U.S. census records and machine learning methods, we identify the place of residence for family members of Black individuals who were killed by lynch mobs between 1882 and 1929 in the U.S. South. Over the entire period, our analysis finds that lynch victims' family members experienced a 10-percentage-point increase in the probability of migrating to a different county by the next decennial census relative to their same-race neighbors. We also find that surviving family members had a 12-percentage-point increase in the probability of county out-migration compared with their neighbors when the household head was a lynch victim. The out-migration response of the families of lynch victims was most pronounced between 1910 and 1930, suggesting that lynch victims' family members may have been disproportionately represented in the first Great Migration.

Prairie Madness: Mental Illness and Norwegian Immigration to North America in the Late Nineteenth and Early Twentieth Centuries.

In the late nineteenth and twentieth centuries, there was widespread concern about the fate of immigrants to the United States. One area of particular concern was mentally ill immigrants, as illustrated in contemporaneous screening procedures, asylum reports, government commissions, popular media, fiction, and scientific studies. This article examines the depiction of one mentally ill immigrant in O. E. Rølvaag's novel Giants in the Earth within the context of these discussions. The novel, published originally in two parts in 1924 and 1925 in Norwegian, was translated in collaboration with the author into English in 1927. While many explanations were posited for rates of mental illness among immigrants to North America in the late nineteenth and early twentieth centuries, Rølvaag presents a more nuanced view which accounts for mental responses to change of climate, environment, and cultural loss.

Resolving Indigenous village occupations and social history across the long century of European permanent settlement in Northeastern North America: The Mohawk River Valley ~1450-1635 CE.

The timeframe of Indigenous settlements in Northeast North America in the 15th-17th centuries CE has until very recently been largely described in terms of European material culture and history. An independent chronology was usually absent. Radiocarbon dating has recently begun to change this conventional model radically. The challenge, if an alternative, independent timeframe and history is to be created, is to articulate a high-resolution chronology appropriate and comparable with the lived histories of the Indigenous village settlements of the period. Improving substantially on previous initial work, we report here high-resolution defined chronologies for the three most extensively excavated and iconic ancestral Kanien'kehá꞉ka (Mohawk) village sites in New York (Smith-Pagerie, Klock and Garoga), and a fourth early historic Indigenous site, Brigg's Run, and re-assess the wider chronology of the Mohawk River Valley in the mid-15th to earlier 17th centuries. This new chronology confirms initial suggestions from radiocarbon that a wholesale reappraisal of past assumptions is necessary, since our dates conflict completely with past dates and the previously presumed temporal order of these three iconic sites. In turn, a wider reassessment of northeastern North American early history and re-interpretation of Atlantic connectivities in the later 15th through early 17th centuries is required. Our new closely defined date ranges are achieved employing detailed archival analysis of excavation records to establish the contextual history for radiocarbon-dated samples from each site, tree-ring defined short time series from wood charcoal samples fitted against the radiocarbon calibration curve ('wiggle-matching'), and Bayesian chronological modelling for each of the individual sites integrating all available prior knowledge and radiocarbon dating probabilities. We define (our preferred model) most likely (68.3% highest posterior density) village occupation ranges for Smith-Pagerie of ~1478-1498, Klock of ~1499-1521, Garoga of ~1550-1582, and Brigg's Run of ~1619-1632.

"I have had an exceedingly beautiful life" The Jewish gynecopathologist Robert Meyer (1864-1947) and his extraordinary response to Nazi repression.

The Jewish scientist Robert Meyer received worldwide professional recognition as a pioneer gynecopathologist. Before his death, he wrote a memoir in which he gave an entirely positive assessment of his life. The latter, however, is at odds with the fact that he was disenfranchised by the National Socialists and driven into emigration. But even before Hitler's seizure of power, he had to cope with several strokes in private as well as in professional life. This article takes these apparent inconsistencies as an occasion for a fundamental analysis of Robert Meyer's life and work. Special attention is paid to his scientific achievements, but also to repressive experiences in the Third Reich, the background of his emigration and his specific handling of these adversities. Various archival documents, Meyer's memoirs, and other contemporary writings by and about Robert Meyer and about the development of the field of gynecopathology serve as central sources. The study concludes that Meyer made fundamental contributions to the embryology of the vagina, ovarian tumors, cancer diagnosis, endometriosis, and genital and fetal abnormalities. Despite his scientific merits, he was never granted a regular professorship - mainly, because he was professionally caught between two stools (gynecology and pathology), but also due to low career ambition. Nevertheless, thanks to influential supporters, he was able to hold out in Germany until 1939, when he emigrated to the United States. Meyer considered his life "beautiful" despite many misfortunes because he defined happiness in life primarily in terms of fulfilling personal relationships and was willing to accept life as it comes. In addition, he found distraction and fulfillment in his scientific work.

Four Athenas - Europe's first female neurosurgeons.

In the early 20th century, a tumultuous era was yielding geopolitical and social change. Europe at large was undergoing redefinition of borders, political structures, and economies, while rebuilding societies after World War I. At the same time, neurosurgery was emerging as a new specialty, and women were allowed to study medicine for the first time in many European countries. These factors created a synergy, setting the stage for Europe's four first female neurosurgeons to emerge. In 1924, Germany's Alice Rosenstein began her neurosurgical career and contributed to the refinement of pneumoencephalography. Due to her Jewish background, she was forced to flee Europe, emigrating to the United States, where she did not continue to practice neurosurgery. In 1929, Russia's Serafima Bryusova began her neurosurgical training. She studied intracranial pressure in trephined patients and wrote the first Russian monograph on cerebral angiography before she was immobilized by severe arthritis. England's Diana Beck began her neurosurgical career in 1939. She contributed to the surgical treatment of intracerebral hemorrhage and researched idiopathic intracranial hypertension, even though many believed she could not be a successful surgeon due to her myasthenia gravis. In 1943, Romania's Sofia Ionescu started a prolific academic neurosurgical career. She developed a minimally-invasive technique to treat intracerebral hematomas and worked tirelessly to bring neurosurgery to all corners of her country. Europe's first women in neurosurgery were marked by war and adversity. Their stories carry within them a spirit of resilience, fortitude, and tenacity that continues to characterize women in neurosurgery today.

Success or failure? Pathologists persecuted under National Socialism and their careers after emigrating to the United States.

This study examines the biographies of pathologists persecuted by the National Socialists after their emigration from the German Reich to the USA. The work is based on primary sources from various archives and a systematic evaluation of secondary literature on the persons concerned. The study yields five central results: (1) Out of 118 identified persecuted pathologists, a total of 91 persons left the German Reich, 60 of them demonstrably to the USA. (2) The majority of the pathologists immigrated to the USA between 1938 and 1941. (3) A good two thirds of the pathologists were (again) employed in the USA as university teachers, the majority in the leading position of Full Professor. (4) The preferred area of employment was the East Coast of the USA. (5) The labor market situation was particularly favorable for specialized pathologists. It can be concluded that the majority of the emigrated pathologists studied succeeded in continuing or even expanding their professional careers in the USA, with existing academic networks playing a noticeable role. Pathology thus occupies a special position in the context of the migration history of persecuted physicians under National Socialism.

Fleeing mass starvation: what we (do not) know about the famine-migration nexus.

The relationship between famine and migration has not been studied adequately to date. A systematic review of scholarship centred on famine and its demographic, political, and socioeconomic effects demonstrates the paucity of academic attention to the issue. This paper surveys the dominant hypotheses and findings regarding the connection between famine and migration. It delineates key questions that an interdisciplinary and case-based exploration of the subject should address, highlighting gaps in the literature with respect to population-level analyses. Primary observations about the literature reviewed include tenuous generalisations about the linkage between famine and migration and partial examination of the role of politics in enabling or prohibiting mobility during hunger-related crises. In addition, disciplinary silos influence which particular aspects of a famine are scrutinised and which are not appraised. In view of these concerns, international legal and humanitarian norms governing migration also need to pay closer attention to its association with famine.

The early Aurignacian dispersal of modern humans into westernmost Eurasia.

Documenting the first appearance of modern humans in a given region is key to understanding the dispersal process and the replacement or assimilation of indigenous human populations such as the Neanderthals. The Iberian Peninsula was the last refuge of Neanderthal populations as modern humans advanced across Eurasia. Here we present evidence of an early Aurignacian occupation at Lapa do Picareiro in central Portugal. Diagnostic artifacts were found in a sealed stratigraphic layer dated 41.1 to 38.1 ka cal BP, documenting a modern human presence on the western margin of Iberia ∼5,000 years earlier than previously known. The data indicate a rapid modern human dispersal across southern Europe, reaching the westernmost edge where Neanderthals were thought to persist. The results support the notion of a mosaic process of modern human dispersal and replacement of indigenous Neanderthal populations.

A multi-isotope, multi-tissue study of colonial origins and diet in New Zealand.

OBJECTIVES: Colonial period New Zealand was lauded as a land of plenty, where colonists could improve their station in life and secure a future for their families. Our understanding of colonial experience, however, is often shaped by historical records which communicate a state-sponsored version of history. This study aims to reconstruct the lives of settlers using isotopic evidence from the colonial skeletons themselves. MATERIALS AND METHODS: We use skeletal remains from recently excavated colonial sites in Otago (South Island, New Zealand) to illustrate the information that can be gleaned from the isotopic analysis of individuals. We use 87 Sr/86 Sr to identify European settlers, and δ13 C and δ15 N from collagen and hair keratin, as well as dental enamel carbonate δ13 C to trace dietary change over their life-courses. RESULTS: Strontium isotope analysis shows that all adults in our sample are non-local. Dietary isotopes show that while most individuals had relatively consistent childhood diet, one individual with more rural origins likely had seasonal use of resources during childhood. While some members of the population seem to have increased their meat intake in the new colony most do not have clear evidence for this. DISCUSSION: We show the diversity of human experience in first-generation New Zealanders both prior to emigration and in the new colony. Despite colonial propaganda claiming that circumstances in New Zealand were improved for all settlers, we have little evidence for this, aside from among individuals of potentially high status.

Terapia ocupacional en situaciones de emergencia: reflexiones desde la historia / Occupational therapy in emergency situations: reflections from history

The main objective of this article is to provide reflections on the potential impact of the VOC-19 pandemic on the future of occupational therapy based on the analysis of other emergencies that occurred in the first half of the 20th century

A family affair: Evidence of chain migration during the mass emigration from the county of Halland in Sweden to the United States in the 1890s.

This paper examines the influence of individual and household factors on an individual's propensity to emigrate from Halland, a region in south-west Sweden, to the United States during the era of mass migration in the late nineteenth century. The study has a case-control design, using individual-level longitudinal data for a group of emigrants (cases) and a group of non-emigrants (controls). Results indicate the importance of a family's emigration history; individuals whose relatives had previously moved to the United States were more likely to emigrate themselves. In addition, the results also show how this impact varied between groups and how other factors relating to the individual's life situation affected the migration decision. Thus, this paper shows how chain migration and migration networks play important roles during times of mass migration.

Ancient Rome: A genetic crossroads of Europe and the Mediterranean.

Ancient Rome was the capital of an empire of ~70 million inhabitants, but little is known about the genetics of ancient Romans. Here we present 127 genomes from 29 archaeological sites in and around Rome, spanning the past 12,000 years. We observe two major prehistoric ancestry transitions: one with the introduction of farming and another prior to the Iron Age. By the founding of Rome, the genetic composition of the region approximated that of modern Mediterranean populations. During the Imperial period, Rome's population received net immigration from the Near East, followed by an increase in genetic contributions from Europe. These ancestry shifts mirrored the geopolitical affiliations of Rome and were accompanied by marked interindividual diversity, reflecting gene flow from across the Mediterranean, Europe, and North Africa.

Ancient DNA and contemporary politics: The analysis of ancient DNA challenges long-held beliefs about identity and history with potential for political abuse.

The sequencing and analysis of ancient human DNA has helped to rewrite human history. But it is also tempting politicians, nationalists and supremacists to abuse this research for their agendas.

In the shadow of National Socialism: Early emigration and suicide of the oral pathologist Rudolf Kronfeld (1901-1940).

The physician Rudolf Kronfeld (1901-1940) is undoubtedly one of the pioneering and most influential representatives of modern histopathology and oral pathology. Already at a young age he became a protagonist of the renowned, internationally leading "Vienna School". Kronfeld's outstanding professional significance stands in a peculiar contrast to the research situation to date: His curriculum vitae, but also his family background - and here in particular the fate of his family members in the Third Reich - have received little attention so far. Thus, the present study attempts to shed light on Kronfeld's life and work and, in particular, the complex implications of his Jewish background. It is based on archival sources and a systematic re-analysis of the relevant specialist literature. The analysis demonstrates that Kronfeld's early emigration was driven in part by the anti-Semitism that was tangible in Vienna in the 1920s. The last years of his life were considerably burdened by a serious illness and by repressive experiences which his Jewish family members and companions underwent after the "Anschluss" of Austria into Nazi Germany. Both essential events presumably contributed significantly to Kronfeld's sudden suicide in 1940, at the height of his professional success.
