What ancient DNA reveals about the ubiquitous rockfish of the Pacific Coast of North America
Ancient DNA Identification of Giant Snakehead (Channa micropeltes) Remains from the Market Street Chinatown and Some Implications for the Nineteenth-Century Pacific World Fish Trade
This study presents the results of ancient DNA analyses of eight snakehead (Channasp.) bones from the Market Street Chinatown, a nineteenth-century Chinese diaspora archaeological site in San Jose, California. The sequences of a short stretch of the mitochondrial DNA identify the Market Street Chinatown snakeheads as Giant Snakehead (Channa micropeltes), a species native to Southeast Asia. These results provide the first archaeological evidence o…
Finny Merchandise
During California’s Gold Rush of 1849-1855, thousands of miners rushed to San Francisco, Sacramento, and elsewhere throughout northern California, creating a significant demand for food. In this work, we investigate the role of Atlantic cod (Gadus morhua) and Pacific cod (G. macrocephalus) during the Gold Rush era using historical records, ancient DNA, and vertebral morphology in the cod assemblage recovered from Thompson’s Cove (CA-SFR-186H), a …
Testing for Mississippian Period Turkey Management in the Archaeological Record of the Southeastern United States
People living in Mesoamerica and what is now the eastern and southwestern United States used turkeys (Meleagris gallopavo) as sources of meat, eggs, bones, and feathers. Turkey husbandry and domestication are confirmed in two of these regions (Mesoamerica and the American Southwest), but human-turkey interactions in Eastern North American (eastern United States and Canada) are not fully explored. We apply stable isotope (δ13C, δ15N) and ancient m…
Constrained Agency while Negotiating Spanish Colonialism
Spanish colonial rule in Peru was marked by dramatic changes to indigenous mortuary customs, bodily practices, and morbidity profiles. However, that era of transformation was not solely shaped by Spanish policies; Native Andeans creatively negotiated with those newcomers, sculpting novel practices that sometimes integrated, and other times challenged, the Spanish agenda. Theoretical perspectives on the constrained agency of indigenous communities…
Genetic Diversity and Relationships of Tlingit Moieties
The Tlingit from Southeast Alaska belong to the Northwest Coast cultural tradition, which is defijined by regionally shared sociocultural practices. A distinctive feature of Tlingit social organization is the matrilineal exogamous marriage system among clans from two opposite moieties: the Raven/Crow and Eagle/Wolf. Clan and moiety membership are determined by matrilineal descent, and previous genetic studies of Northwest Coast populations have s…
Applications of Bayesian Skyline Plots and Approximate Bayesian Computation for Human Demography
Bayesian methods have been adopted by anthropologists for their utility in resolving complex questions about human history based on genetic data. The main advantages of Bayesian methods include simple model comparison, presenting results as a summary of probability distributions, and the explicit inclusion of prior information into analyses. In the fijield of anthropological genetics, for example, implementing Bayesian skyline plots and approxima…

Ancient DNA Analysis and Stable Isotope Ecology of Sea Turtles (Cheloniidae) from the Gold Rush-era (1850s) Eastern Pacific Ocean
Historical and archaeological evidence documents the importation of sea turtles from the eastern Pacific Ocean (Baja California) to California during the Gold Rush (1848–1855) and through the end of 19th century, but it is unknown whether these 19th century sea turtles foraged in similar ways to their modern counterparts. To identify the species of two Gold Rush-era sea turtle specimens recovered from archaeological deposits in San Francisco, Cal…

Turkeys on the fringe
Previous research reporting stable carbon (δ13C) and nitrogen (δ15N) isotope values of prehistoric turkey (Meleagris gallopavo) remains from the American Southwest indicates that these birds were husbanded in consistent ways: the majority of samples suggest a diet dominated by maize, a domesticate that uses the C4 photosynthetic pathway. However, most of these studies have focused on turkey remains from locations where maize would likely have bee…
Cultural and Genetic Contexts for Early Turkey Domestication in the Northern Southwest
The turkey (Meleagris gallopavo) was independently domesticated in Mesoamerica and the Southwest, the latter as the only case of Native American animal domestication north of Mexico. In the upland (non-desert) portion of the American Southwest, distinctive closely related mtDNA lineages belonging to haplogroup H1 (thought to indicate domestication) occur from ca. 1 A.D. (Basketmaker II period) through early historic times. At many sites, low freq…
Genomic evidence for the Pleistocene and recent population history of Native Americans
Genetic history of Native Americans Several theories have been put forth as to the origin and timing of when Native American ancestors entered the Americas. To clarify this controversy, Raghavan et al. examined the genomic variation among ancient and modern individuals from Asia and the Americas. There is no evidence for multiple waves of entry or recurrent gene flow with Asians in northern populations. The earliest migrations occurred no earlier…
Origins of an Unmarked Georgia Cemetery Using Ancient DNA Analysis
Determining the origins of those buried within undocumented cemeteries is of incredible importance to historical archaeologists and, in many cases, the nearby communities. In the case of Avondale Burial Place, a cemetery in Bibb County, Georgia, in use from 1820 to 1950, all written documentation of those interred within it has been lost. Osteological and archaeological evidence alone could not describe, with confidence, the ancestral origins of …
Ancient marine hunter‐gatherers from P atagonia and T ierra D el F uego
OBJECTIVES: The human population history from Patagonia and Tierra del Fuego has been of great interest in the context of the American peopling. Different sources of evidence have contributed to the characterization of the local populations, but some main questions about their history remain unsolved. Among the native populations, two marine hunter-gatherers groups inhabited the Patagonian channels below the 478S: Kawéskar and Yámana. Regardless …

Late Pleistocene Human Skeleton and mtDNA Link Paleoamericans and Modern Native Americans
American Beauty Modern Native American ancestry traces back to an East Asian migration across Beringia. However, some Native American skeletons from the late Pleistocene show phenotypic characteristics more similar to other, more geographically distant, human populations. Chatters et al. (p. 750 ) describe a skeleton with a Paleoamerican phenotype from the eastern Yucatan, dating to approximately 12 to 13 thousand years ago, with a relatively com…

IntroductionProviding a Venue for Influential Research in Anthropological Genomics Ripan S. Malhi and Brian M. Kemp, Executive Editors We would like to thank the previous editorial team of Human Biology for improving the journal in numerous ways. By decreasing the review period to three months and over doubling the impact factor, Franz Manni and his team placed the journal back on a track of success. Since taking over the editorship almost a year…
How Much DNA Is Lost? Measuring DNA Loss of Short-Tandem-Repeat Length Fragments Targeted by the PowerPlex 16® System Using the Qiagen MinElute Purification Kit
The success in recovering genetic profiles from aged and degraded biological samples is diminished by fundamental aspects of DNA extraction, as well as its long-term preservation, that are not well understood. While numerous studies have been conducted to determine whether one extraction method was superior to others, nearly all of them were initiated with no knowledge of the actual starting DNA quantity in the samples prior to extraction, so the…
Brief communication
In this study, we explore the geographic and temporal distribution of a unique variant of the O blood group allele called O1v G542A , which has been shown to be shared among Native Americans but is rare in other populations. O1v G542A was previously reported in Native American populations in Mesoamerica and South America, and has been proposed as an ancestry informative marker. We investigated whether this allele is also found in the Tlingit and …
Genetic analysis of early holocene skeletal remains from Alaska and its implications for the settlement of the Americas
Mitochondrial and Y‐chromosome DNA were analyzed from 10,300‐year‐old human remains excavated from On Your Knees Cave on Prince of Wales Island, Alaska (Site 49‐PET‐408). This individual's mitochondrial DNA (mtDNA) represents the founder haplotype of an additional subhaplogroup of haplogroup D that was brought to the Americas, demonstrating that widely held assumptions about the genetic composition of the earliest Americans are incorrect. The amo…
The Neolithic Demographic Transition in the U.S. Southwest
Maize agriculture was practiced in the U.S. Southwest slightly before 2000 B.C., but had a negligible impact on population growth rates until the development or introduction of more productive landraces; the ability to successfully cultivate maize under a greater variety of conditions, with dry farming especially important; the addition of beans, squash, and eventually turkey to the diet; increased sedentism; and what we infer to be the remapping…

Native American mtDNA prehistory in the American Southwest
This study examines the mtDNA diversity of the proposed descendants of the multiethnic Hohokam and Anasazi cultural traditions, as well as Uto‐Aztecan and Southern‐Athapaskan groups, to investigate hypothesized migrations associated with the Southwest region. The mtDNA haplogroups of 117 Native Americans from southwestern North America were determined. The hypervariable segment I (HVSI) portion of the control region of 53 of these individuals was…
The genetic impact of aztec imperialism
In AD 1428, the city‐states of Tenochtitlan, Texcoco, and Tlacopan formed the Triple Alliance, laying the foundations of the Aztec empire. Although it is well documented that the Aztecs annexed numerous polities in the Basin of Mexico over the following years, the demographic consequences of this expansion remain unclear. At the city‐state capital of Xaltocan, 16th century documents suggest that the site's conquest and subsequent incorporation in…
Sex Identification of Children Sacrificed to the Ancient Aztec Rain Gods in Tlatelolco
Recent excavations of Temple R, dedicated to the Aztec god of wind and rain, Ehecatl-Quetzalcoatl, at the archaeological site of Tlatelolco, Mexico City, recovered the sacrificial remains of 37 subadults and 6 adults. It is believed that this ceremonial complex was the site of an extraordinary ceremony carried out during the great drought and famine of AD 1454-57, a date consistent with the founding of this temple. The ages of 31 subadults and 1 …
Distribution of Y chromosomes among native North Americans
In this study, 231 Y chromosomes from 12 populations were typed for four diagnostic single nucleotide polymorphisms (SNPs) to determine haplogroup membership and 43 Y chromosomes from three of these populations were typed for eight short tandem repeats (STRs) to determine haplotypes. These data were combined with previously published data, amounting to 724 Y chromosomes from 26 populations in North America, and analyzed to investigate the geograp…

DNA analysis of ancient dogs of the Americas
Quids and Aprons
The success of ancient DNA (aDNA) studies rests on the preservation of DNA through time, and can be limited by the availability of skeletal samples from particular times and locations. To help overcome this limitation, we sought to extract, amplify, and type human mitochondrial DNA (mtDNA) preserved within 1000- to 2000+-year-old artifacts from the American Southwest. In this study, we successfully typed mtDNA from 21 quids and aprons from Basket…
Exploring prehistory in the North American southwest with mitochondrial DNA diversity exhibited by Yumans and Athapaskans
A recent study of mitochondrial DNA variation in Native American populations from the American Southwest detected signatures of a population expansion of subhaplogroup B2a, dated to 2,105 years before present (99.5% confidence interval, 1,273–3,773 YBP), following the introduction and intensification of maize agriculture in the region. Only one Yuman group and no Athapaskan speakers were analyzed in previous studies. Here we report mtDNA haplogro…
Nondestructive sampling of human skeletal remains yields ancient nuclear and mitochondrial DNA
Museum curators and living communities are sometimes reluctant to permit ancient DNA (aDNA) studies of human skeletal remains because the extraction of aDNA usually requires the destruction of at least some skeletal material. Whether these views stem from a desire to conserve precious materials or an objection to destroying ancestral remains, they limit the potential of aDNA research. To help address concerns about destructive analysis and to min…

Genetic continuity after the collapse of the Wari empire
The Wari empire flourished in the central, highland Peruvian Andes from AD 600–1000, and although the events that led to its demise are unknown, archaeological evidence indicates that Wari control waned at the end of the first millennium. Here, we test the hypothesis that, despite the major shift in social and political organization at the fall of the Wari empire, the mitochondrial DNA (mtDNA) composition of populations from the Ayacucho Basin, t…

Genetics and the History of Latin America
Given that we live in the much-vaunted era of the “genomics revolution,” one cannot help but wonder whether those long strands of DNA will ever wash up on the historian’s lonely shore. Sure, we are all aware of one or two high-profile instances when genetic evidence was able to change a historical interpretation. The case that most readily comes to mind is the Y-chromosome DNA test conducted by a retired pathologist in Charlottesville, Virginia, …
Population structure and admixture in Cerro Largo, Uruguay, based on blood markers and mitochondrial DNA polymorphisms
Recent studies of the Uruguayan population revealed different amounts of Amerindian and African genetic contributions. Our previous analysis of Afro‐Uruguayans from the capital city of the Department of Cerro Largo showed a high proportion of African genes, and the effects of directional mating involving Amerindian women. In this paper, we extended the analysis to a sample of more than 100 individuals representing a random sample of the populatio…

Mitochondrial DNA of Protohistoric Remains of an Arikara Population from South Dakota
Mitochondrial DNA (mtDNA) was extracted from skeletal remains excavated from three Arikara sites in South Dakota occupied between AD 1600 and 1832. The diagnostic markers of four mtDNA haplogroups to which most Native Americans belong (A, B, C, and D) were successfully identified in the extracts of 55 (87%) of the 63 samples studied. The frequencies of the four haplogroups were 42%, 29%, 22%, and 7%, respectively, and principal coordinates analys…
