The last few years have witnessed an explosive generation of genomic data from ancient and modern Native American populations. These data shed light on key demographic shifts that occurred in geographically diverse territories of South America, such as the Andean highlands, Southern Patagonia and the Amazon basin. We used genomic data to study the recent population history of the Mapuche, who are the major Native population from the Southern Cone (Chile and Argentina). We found evidence of specific shared genetic ancestry between the Mapuche and ancient populations from Southern Patagonia, Central Chile and the Argentine Pampas. Despite previous evidence of cultural influence of Inca and Tiwanaku polities over the Mapuche, we did not find evidence of specific shared ancestry between them, nor with Amazonian groups. We estimated the effective population size dynamics of the Mapuche ancestral population during the last millennia, identifying a population bottleneck around 1650 AD, coinciding with a period of Spaniards invasions into the territory inhabited by the Mapuche. Finally, we show that admixed Chileans underwent post-admixture adaptation in their Mapuche subancestry component in genes related with lipid metabolism, suggesting adaptation to scarce food availability.

This chapter examines how King Philip’s War gave rise to a significant but often ignored or misperceived history of bondage, enslavement, and diaspora that took Native Americans far from their northeast homelands, and subjected them to a range of brutal conditions across an Atlantic World. It focuses on Algonquians’ transits into captivity as a consequence of the war, and historicizes this process within longer trajectories of European subjugation of Indigenous populations for labor. The chapter examines how Algonquian individuals and families were forcibly placed into New England colonial as well as Native communities at the war’s conclusion, and how others were transported out of the region for sale across the Atlantic World. The case of King Philip’s wife and son is especially complex, and the chapter considers how traditions around their purported sale into slavery in Bermuda interact with challenging racial politics and archival traces. Modern-day “reconnection” events have linked St. David’s Island community members in Bermuda to Native American tribes in New England. The chapter also reflects on wider dimensions of this Algonquian diaspora, which likely brought Natives to the Caribbean, Azores, and Tangier in North Africa, and propelled Native migrants/refugees into Wabanaki homelands.

The Spanish conquest of the Americas was one of the most dramatic cultural and biological transformations in the history of the world. Small groups of conquistadores toppled enormous empires. Millions of Native Americans died from epidemic disease. Old World animals and plants revolutionized Native American societies, while New World crops fundamentally altered the diet and land-tenure of peasants across Europe. In the words of historian Alfred Crosby (1972: 3),The two worlds, which God had cast asunder, were reunited, and the two worlds, which were so very different, began on that day [I1 October 14921 to become alike.

This chapter provides an overview of landscape studies in archaeology, particularly as practiced in the southeastern United States. There is an extended discussion justifying historical anthropology as an important point of departure for this study, in particular because of its usefulness for exploring processes of colonialism. The chapter provides summaries of the major Native American groups and European powers that appear in the remainder of the volume. Generally speaking, the three major European players, or the Spanish, English, and French had different goals and methods of colonization. These methods cumulatively spurred a highly ramified history of landscape transformations for Native Americans. The chapter’s approach resonates well with post-colonial approaches that attempt to decolonize the past by removing Europeans as the primary lens by which we view the actions of Indigenous peoples. Working under rubrics such as “Native-lived colonialism” and “decolonizing the past,” archaeologists increasingly are seeking to integrate European texts, the archaeological record, oral histories, and the perspectives of Native peoples to try and achieve a plural perspective on past lifeways.

In spite of the nativism that agitated the United States during the second quarter of the nineteenth century, the Catholic Church experienced a noticeable drift of native American converts from other denominations. Between 1841 and 1857 the increased number of converts included a significant sprinkling of Protestant ministers. The history of this movement, which had its paradigm in the Oxford Movement, will be treated more in detail elsewhere. The purpose of this essay is simply to recount the attempt by several converts to establish a religious congregation of men dedicated to the Catholic apostolate among native Americans.

Much of the discussion about North American precontact and contact-period populations has focused on continent-wide estimates. Although the associated work has produced valuable information on the demographic and cultural history of the continent, it has failed to generate agreed-upon estimates, population trends, or detailed demographic knowledge of Native American cultures. Using archaeological settlement remains and methods developed in recent research on Iroquoian cultures, this study estimates and examines population trends for the Onondaga and Oneida cultures of the Haudenosaunee (Iroquois) from A.D. 1500 to 1700. Onondaga population appears to have increased until the mid—seventeenth century, when drastic declines in settlement area and population size occurred. This depopulation event is both several decades after first contact with Europeans and at least a decade after the first known depopulation event among the Haudenosaunee. Oneida populations show a much more complex history that suggests the need for more detailed analyses of contact-period Native American population data. In conjunction with archaeological evidence and ethnohistoric information, the population trends generated by this study create a model of two precontact Native American populations and display the effects of European contact on those populations.

AbstractBackgroundWhole human genome sequencing initiatives provide a compendium of genetic variants that help us understand population history and the basis of genetic diseases. Current data mostly focuses on Old World populations and information on the genomic structure of Native Americans, especially those from the Southern Cone is scant.ResultsHere we present a high-quality complete genome sequence of 11 Mapuche-Huilliche individuals (HUI) from Southern Chile (85% genomic and 98% exonic coverage at > 30X), with 96–97% high confidence calls. We found approximately 3.1×106 single nucleotide variants (SNVs) per individual and identified 403,383 (6.9%) of novel SNVs that are not included in current sequencing databases. Analyses of large-scale genomic events detected 680 copy number variants (CNVs) and 4,514 structural variants (SVs), including 398 and 1,910 novel events, respectively. Global ancestry composition of HUI genomes revealed that the cohort represents a marginally admixed population from the Southern Cone, whose genetic component is derived from early Native American ancestors. In addition, we found that HUI genomes display highly divergent and novel variants with potential functional impact that converge in ontological categories essential in cell metabolic processes.ConclusionsMapuche-Huilliche genomes contain a unique set of small– and large-scale genomic variants in functionally linked genes, which may contribute to susceptibility for the development of common complex diseases or traits in admixed Latinos and Native American populations. Our data represents an ancestral reference panel for population-based studies in Native and admixed Latin American populations.

Since the 19th century, the addax (Addax nasomaculatus) has lost approximately 99% of its former range. Along with its close relatives, the blue antelope (Hippotragus leucophaeus) and the scimitar-horned oryx (Oryx dammah), the addax may be the third large African mammal species to go extinct in the wild in recent times. Despite this, the evolutionary history of this critically endangered species remains virtually unknown. To gain insight into the population history of the addax, we used hybridization capture to generate ten complete mitochondrial genomes from historical samples and assembled a nuclear genome. We found that both mitochondrial and nuclear diversity are low compared to other African bovids. Analysis of mitochondrial genomes revealed a most recent common ancestor ~32 kya (95% CI 11–58 kya) and weak phylogeographic structure, indicating that the addax likely existed as a highly mobile, panmictic population across its Sahelo–Saharan range in the past. PSMC analysis revealed a continuous decline in effective population size since ~2 Ma, with short intermediate increases at ~500 and ~44 kya. Our results suggest that the addax went through a major bottleneck in the Late Pleistocene, remaining at low population size prior to the human disturbances of the last few centuries.

AbstractHuman populations have a complex history of introgression and of changing population size. Human genetic variation has been affected by both these processes, so that inference of past population size depends upon the pattern of gene flow and introgression among past populations. One remarkable aspect of human population history as inferred from genetics is a consistent “wave” of larger effective population size, prior to the bottlenecks and expansions of the last 100,000 years. Here I carry out a series of simulations to investigate how introgression and gene flow from genetically divergent ancestral populations affect the inference of ancestral effective population size. Both introgression and gene flow from an extinct, genetically divergent population consistently produce a wave in the history of inferred effective population size. The time and amplitude of the wave reflect the time of origin of the genetically divergent ancestral populations and the strength of introgression or gene flow. These results demonstrate that even small fractions of introgression or gene flow from ancient populations may have large effects on the inference of effective population size.

Religion was a point of cultural conflict, political motivation, and legal justification throughout the European and American colonization of North America. Beginning in the 14th century, Catholic monarchs invoked Christian doctrine and papal law to claim Native American “heathenry” or “infidelity” as legal grounds that legitimized or mandated their policies of military invasion and territorial occupation. More progressive Christian thinkers argued for the recognition of Native Americans as human beings entitled to certain natural-law protections that morally obligated Spain to conquer and convert them for their own benefit. Spain and France worked with the church throughout the 16th and 17th centuries to establish missions throughout seized Native American territories, while English colonists often segregated Native Americans into “praying towns” for their moral benefit or the sanctity of the colonies. After the United States declared independence, American politicians quickly identified dissolution of Native American cultures as a necessary step in undermining tribal saliency and in ensuring the political dominion of state and federal governments. By the 19th century, policymakers were convinced that encouraging Indians to put aside their “savage ways” would help tribal populations achieve cultural and spiritual salvation through Christianity. In 1869, President Grant initiated a “Peace Policy” that granted Christian missions contracts and federal funding to civilize and Christianize the Native American peoples of assigned reservations. The federal government established boarding schools for the children of tribal communities to teach English, Christianity, and occupational skills in order to “Kill the Indian in him and Save the Man.” During the 19th and 20th centuries, federal legislation stripped Native Americans of lands, property, and rights, while federal agencies forbade the practice of indigenous Native American religions. Subsequent courts legitimated the historic claim of European nations to Native American lands pursuant to the “Doctrine of Discovery,” thus ruling these policies either legal or unreviewable. While judicial decisions throughout the 20th century also recognized tribal rights to land, water, and self-government as well as the legal obligation of the federal government to protect tribal resources, these rulings have been inconsistently realized. Throughout the history of the United States, law has articulated, in the language of privilege, right, and moral prescription, American values and visions of ideal relations. As American culture has changed, federal policy has swung back and forth among initiatives to relocate, terminate, assimilate, and appropriate Native American cultures. Religion and law have advanced agendas of conquest and colonization and become means by which Native Americans peoples have resisted those agendas.

In the second half of the nineteenth century, Americans swarmed to take in a raft of new illustrated journals and papers. Engravings and drawings of “buckskinned braves” and “Indian princesses” proved an immensely popular attraction for consumers of publications like Frank Leslie's Illustrated Newspaper and Harper's Weekly. This book charts a social and cultural history of Native American illustrations—romantic, violent, racist, peaceful, and otherwise—in the heyday of the American pictorial press. These woodblock engravings and ink drawings placed Native Americans into categories that drew from venerable “good” Indian and “bad” Indian stereotypes already threaded through the culture. The book's examples show how the genre cemented white ideas about how Indians should look and behave—ideas that diminished Native Americans' cultural values and political influence. The book's powerful analysis of themes and visual tropes unlock the racial codes and visual cues that whites used to represent, and marginalize, native cultures already engaged in a twilight struggle against inexorable westward expansion.
