Multiple studies have demonstrated that European colonization of the Americas led to the death of nearly all North American dog mitochondrial lineages and replacement with European ones sometime between AD 1492 and the present day. Historical records indicate that colonists imported dogs from Europe to North America, where they became objects of interest and exchange as early as the seventeenth century. However, it is not clear whether the earliest archaeological dogs recovered from colonial contexts were of European, Indigenous, or mixed descent. To clarify the ancestry of dogs from the Jamestown Colony, Virginia, we sequenced ancient mitochondrial DNA from six archaeological dogs from the period 1609–1617. Our analysis shows that the Jamestown dogs have maternal lineages most closely associated with those of ancient Indigenous dogs of North America. Furthermore, these maternal lineages cluster with dogs from Late Woodland, Hopewell, and Virginia Algonquian archaeological sites. Our recovery of Indigenous dog lineages from a European colonial site suggests a complex social history of dogs at the interface of Indigenous and European populations during the early colonial period.

The Wichita and Affiliated Tribes have a long history of occupation in what is now known as Oklahoma. This includes evidence of habitations along Camp Creek and Sugar Creek near Anadarko in Caddo County. Here Wichita peoples camped, built grass houses and arbors, and held social gatherings leading up to and following the passing of the General Allotment Act in 1887. After allotment, communal camp and dance grounds were especially important focal points for community building. These places, such as the ichaskhah camp and dance ground discussed in this article, are critical to understanding the multigenerational connections between ancestral and living Wichita peoples. This history is also important to the community today. However, archaeological research of the Allotment period is exceptionally rare in this region. By using collaborative and Indigenous archaeological methodologies, this work documents the complexities of these places, challenging traditional assumptions of allotment-era cultural loss and assimilation.

In 2013, 36 Ancestors of African descent were identified in an unmarked eighteenth-century burial ground during construction in Charleston, South Carolina. The site, later referred to as the Anson Street African Burial Ground, was buried beneath the growing city and forgotten in the centuries that followed. The ethical treatment of these ancestral remains was of paramount importance to our community. Historically, narratives relating to the lives of African descendant people in Charleston have been inadequately documented and shared. For these reasons, we engaged the local African American community in a multifaceted memorialization process. Together, we sought to sensitively ensure that the Ancestors’ identities and lives were fully explored according to the collective descendant community's wishes. To this end, we involved the community in researching and celebrating the Ancestors’ lives through arts and education programs and analyzed their and community members’ DNA to elucidate their ancestry. Our engagement initiatives increased access for all ages to archaeological, historical, and genetic research and encouraged active participation in the design of a permanent memorial. The Anson Street African Burial Ground Project provides a successful example of community-engaged activist archaeology focused on honoring the Ancestors and their descendants.

This study explores the pig-raising practices of Chinese migrants in Los Angeles Chinatown during the Chinese Exclusion Era. Chinese butcher shops sold pork meat, and previous research indicates that they likely sold the more profitable parts outside of Chinatown for additional income while consuming cheaper cuts themselves. Using dental calculus analysis and archival research, this study further explores how Chinatown residents relied on pork to thrive in an anti-Chinese environment. Dental calculus results suggest that Chinese migrants raised their own pigs with food waste and by-products from rice fields; this pork was then sold to meat markets or consumed within the community. The analysis of immigration records indicates that Chinese butcher shops provided employment opportunities as well as housing, banking, and immigration support for Chinese migrants. Pig raising, therefore, not only supplied a source of meat for Chinese migrants but also supported a range of social and financial services for a marginalized group that faced everyday discrimination from dominant society. Overall, this study traces the labor and networks that small businesses in the late nineteenth and early twentieth centuries needed to source and distribute pork, and it highlights how a Chinese diasporic community developed a pork production system to resist racism.

Archaeology and cultural evolution theory both predict that environmental variation and population size drive the likelihood of inventions (via individual learning) and their conversion to population-wide innovations (via social uptake). We use the case study of the adoption of the bow and arrow in the Great Basin to infer how patterns of cultural variation, invention, and innovation affect investment in new technologies over time and the conditions under which we could predict cultural innovation to occur. Using an agent-based simulation to investigate the conditions that manifest in the innovation of technology, we find the following: (1) increasing ecological variation results in a greater reliance on individual learning, even when this decreases average fitness due to the costs of learning; (2) decreasing population size increases variability in the types of learning strategies that individuals use; among smaller populations drift-like processes may contribute to randomization in interpopulation cultural diffusion; (3) increasing the mutation rate affects the variability in learning patterns at different rates of environmental variation; and (4) increasing selection pressure increases the reliance on social learning. We provide an open-source R script for the model and encourage others to use it to test additional hypotheses.

This article explores Indigenous perspectives on archaeology in Canada and the United States and the role of archaeologists in engaging with Indigenous communities. As part of our study, we interviewed Indigenous community members about their experiences in archaeology and their thoughts on the discipline. We analyzed each interview thematically to identify patterns of meaning across the dataset and to develop common themes in the interview transcripts. Based on the results of our analysis, we identified six themes in the data: (1) Euro-colonialism damaged and interrupted Indigenous history, and archaeology offers Indigenous community members an opportunity to reconnect with their past; (2) archaeological practices restrict access of Indigenous community members to archaeological information and archaeological materials; (3) cultural resource management (CRM) is outpacing the capacity of Indigenous communities to engage meaningfully with archaeologists; (4) the codification of archaeology through standards, guidelines, and technical report writing limits the goals of the discipline; (5) archaeological methods are inconsistent and based on individual, or company-wide, funding and decision-making; and (6) archaeological software offers a new opportunity for Indigenous communities and archaeologists to collaborate on projects.

Among Líĺwat people of the Interior Plateau of British Columbia, an oral tradition relays how early ancestors used to ascend Qẃelqẃelústen, or Mount Meager. The account maintains that those climbers could see the ocean, which is not the case today, because the mountain is surrounded by many other high peaks, and the Strait of Georgia is several mountain ridges to the west. However, the mountain is an active and volatile volcano, which last erupted circa 2360 cal BP. It is also the site of the largest landslide in Canadian history, which occurred in 2010. Given that it had been a high, glacier-capped mountain throughout the Holocene, much like other volcanoes along the coastal range, we surmise that a climber may have reasonably been afforded a view of the ocean from its prior heights. We conducted viewshed analyses of the potential mountain height prior to its eruption and determined that one could indeed view the ocean if the mountain were at least 950 m higher than it is today. This aligns with the oral tradition, indicating that it may be over 2,400 years old, and plausibly in the range of 4,000 to 9,000 years old when the mountain may have been at such a height.

This article introduces a model that harnesses praxis as a powerful tool for critique, knowledge, and action within the realm of public archaeology. The adopted framework focuses on persistence as a middle-range methodology that bridges the material past to activist and collaborative-based projects. Recent research at Mission La Purísima Concepción in Lompoc, California, shows the effectiveness of this model and its real-world application. Visitors to California missions encounter the pervasive “Mission Myth”—a narrative that systematically overlooks and marginalizes Indigenous presence while perpetuating ideas of White hegemony and Eurocentrism. Archaeological excavations in the Native rancheria and collaboration with members of the Chumash community help resist notions of Indigenous erasure. By activating notions of persistence through public archaeology, this study contributes to dismantling entrenched terminal narratives, paving the way for a more accurate representation of the past and fostering a more inclusive archaeological practice.

In the Salish Sea region, labret adornment with lip plugs signify particular identities, and they are interpreted as emblematic of both membership in horizontal relationships and achieved status for traditional cultures associated with labret wearing on the Northwest Coast (NWC) of North America. Labrets are part of a shared symbolic language in the region, one that we argue facilitated access to beneficial horizontal relationships (e.g., Angelbeck and Grier 2012; Rorabaugh and Shantry 2017). We employ social network analysis (SNA) to examine labrets from 31 dated site components in the Salish Sea region spanning between 3500 and 1500 cal BP. Following this period, the more widely distributed practice of cranial modification as a social marker of status developed in the region. The SNA of labret data shows an elaboration and expansion of antecedent social networks prior to the practice of cranial modification. Understandings of status on the NWC work backward from direct contact with Indigenous societies. Labret wearing begins at the Middle-Late Holocene transition, setting an earlier stage for the horizontal social relationships seen in the ethnohistoric period. These findings are consistent with the practice as signifying restricted group membership based on affinal ties and achieved social status.

This article presents radiocarbon dates on 29 perishable objects deposited in shrine caves in the Jornada and Mimbres Mogollon regions of far west Texas and southern New Mexico. The dated objects include tablita fragments, effigies, prayer sticks, hafted projectile point foreshafts, and flat curved sticks. Analysis of the dates reveals three significant trends: a particular set of Indigenous ritual practices involving shrine caves in the North American Southwest was of extraordinary temporal depth and continuity; the meanings and material culture associated with shrine caves changed through time; and a signature iconographic expression of Jornada and Mimbres origin cosmologies, the Goggle-eye or “Tlaloc” entity, is older than previously understood. The dating of shrine caves and iconographic motifs provides new insights on early eras of religious expression in the southern Southwest, clarifying both the nature and time depth of foundational cosmologies and providing a deep time perspective for interpretations of how such cosmologies and their material and iconographic expressions changed through time.

As regional chronologies become better defined, we are better able to track large-scale population movements and related cultural change. A dataset of 156 radiocarbon dates from the Middle Cumberland Region (MCR), evaluated with 199 more dates from the Ridge and Valley portions of northern Georgia and East Tennessee, enable modeling of population movements from the Central Mississippi Valley into the MCR, as well as subsequent movements and effects in the Ridge and Valley between AD 1200 and 1450. The dissolution of Cahokia is of particular interest, because the MCR falls geographically between the American Bottom and the Ridge and Valley province. This large-scale chronological perspective places key events in this part of the Southeast and Midwest into a unified historical framework that increases our understanding of the timing of cultural events. A related goal is to sort out possible external events and influences that may have affected this large region. This study makes apparent the relationships between cultural events and natural events, such as the drought sequences reported for the Central Mississippi Valley and beyond.

We developed a new approach to identify vulnerabilities to water insecurity across entire archaeological culture areas by combining a paleohydrological model of the sensitivites of hydrological systems to droughts with least-cost analyses of the costs to acquire domestic water. Using a custom Python script integrated into ArcGIS Pro software, we calculated the pairwise one-way cost in time for walking between 225 water sources and 5,446 Ancestral Pueblo cultural sites across the Jemez and Pajarito Plateaus of the Jemez Mountains, New Mexico. This allowed us to identify whether periodic hydrological droughts occurring between AD 1100 and 1700 increased water acquisition costs across these regions. We found that hydrological droughts increased travel times in both regions to durations exceeding modern standards for water insecurity. Beginning in the fourteenth century, greater underlying hydrogeological sensitivities to droughts and the decline of a dual-residence pattern caused by population losses made the remaining aggregated communities of the Pajarito Plateau much more vulnerable to water insecurity than those on the Jemez Plateau. This would have upended long-standing relationships between communities and water on the Pajarito Plateau during a time when socioeconomic integration across the northern Rio Grande Valley pulled people toward valley bottoms.

At the turn of the twentieth century, American logging companies backed by the US colonial regime initiated extensive extraction in Bikol, Philippines. Industrial infrastructure and the involvement of a newly assembled Bikolano workforce left a profound imprint on the region's landscape. This article discusses a collaborative archaeological project that used archival materials, place-name analysis, ethnographic interviews, discussions with local scholars, satellite mapping, and drone-mounted lidar scans of former industrial sites. Findings shed light on the enduring ramifications of American logging in the early 1900s on settlement patterns, the infrastructure of routes and mobility, the state of industries from Philippine independence in 1946 through the 1980s, and ongoing environmental hazards. These findings emphasize the legacy of American empire, reveal the role of Filipino logging workers in shaping the landscape through settlement decisions, and uncover intricate connections across a pan-Pacific American colonial frontier that was shaped by both extractive and settler colonialism. This article adds to an emerging trend in Americanist archaeology in which archaeology investigates recent historical and even contemporary events.

Paleoethnobotanical remains from basketry and cordage from the Paisley Caves offer an opportunity to explore how people engaged with plant communities over time. Fiber identification of textiles, together with radiocarbon dating, contributes new information about landscape use within the Summer Lake Basin. Expanded marshlands during the terminal Pleistocene / Early Holocene created suitable plant communities ideal for fiber technology, specifically wetland monocots and herbaceous dicots—including dogbane and stinging nettle—by 11,000 years ago. This technology is key to subsistence activities and craft production throughout the Holocene. Despite climatic events during the Middle Holocene, in which people transitioned from caves to sites centered on lakeshores and wetlands, the suite of fiber plants and their technological application remains constant. During the Late Holocene, bast fiber material diversified with the addition of flax and milkweed. The presence of flax in particular, a high-elevation plant, may reflect the increased use of upland root collection areas as populations increased. This research provides long-term data on culturally significant native plants used in the manufacture of fiber-based textiles over the last 14,000 years.

Current evidence suggests that Indigenous farmers in the North American Southwest began canal irrigation in the second millennium BC, marking an important change in food production technology. Early canal systems are preserved in alluvial floodplains of the US-Mexico Borderlands region, tend to be deeply buried, and can appear as natural fluvial features. Here I discuss some of the challenges in identifying early canals and associated fields and present case studies from the Santa Cruz River in southern Arizona where buried channels dating as early as 1600–1400 BC were likely human constructed. These small channels share several stratigraphic properties and are consistent with hypotheses of early canal irrigation practiced by small family groups reliant on mixed farming and foraging. Through time, irrigation canal systems expanded in size, resulting in increased labor investment, sedentism, and productivity and facilitating the development of larger irrigation communities. Stratigraphic and geomorphic properties of early canal systems thus far identified along the Santa Cruz River provide a framework for identifying potential early canal evidence in other fine-grained floodplains of the Southwest, thereby improving our understanding of Indigenous agricultural intensification.

The Fremont provide an important case study to examine the resilience of ancient farmers to climatic downturns, because they lived at the far northern margin of intensive maize agriculture in the American West, where the constraints on maize production are made abundantly clear. Using a tree-ring and simulation-based reconstruction of average annual precipitation and maize growing degree days, along with cost-distance to perennial streams, we model spatial variability in Fremont site density in the eastern Great Basin. The results of our analysis have implications for defining the ecological envelope in which farming is a viable strategy across this arid region and can be used to predict where and why maize farming strategies might evolve and eventually collapse as climate changes over time.

Through a commingled, fragmentary assemblage of skeletal remains (MNI = 9) recovered from a 1999 salvage excavation, this article explores the lives and deaths of individuals interred at the Brentwood Poor Farm, Brentwood, New Hampshire (1841–1868). This work demonstrates that bioarchaeological analyses of smaller samples can provide nuanced accounts of marginalization and institutionalization even with scant historical records. The skeletal analysis presented here is contextualized within the larger history of the American poor farm system and compared to similar skeletal samples across the United States. The hardships these individuals faced—poverty, otherness, demanding labor—were embodied in their skeletal remains, manifesting as osteoarthritis, dental disease, and other signs of physiological stress. These individuals’ postmortem fates were also impacted by status; they were interred in unmarked graves, disturbed by construction, and once recovered, were again forgotten for more than 20 years.

Developments in radiocarbon dating and analysis provide new opportunities to develop high-resolution chronologies to explore changes through time. We explore the temporality of what has been called the Poverty Point culture of the lower Mississippi Valley circa 4200 to 3200 cal BP, especially the chronology of the type site, Poverty Point. Because of its complicated material culture elaboration without evidence of agriculture, Poverty Point has been identified as the political and economic center of a complex archaeological culture. The duration of site occupation and the historical relationship between the type site and those assumed to be contemporary are critical variables for explaining the emergence of complexity at this time. Most interpretations require political or evolutionary processes that accumulate gradually over hundreds of years. Our data show, however, that there is no temporal coherence among so-called Poverty Point culture sites; among such sites, Poverty Point was occupied for a relatively short period, and it is younger than many sites thought to be derived from it. Using explicit radiometric hygiene and Bayesian analyses of dates, we reject the idea of a unified Poverty Point culture and argue instead that the Poverty Point site earthworks developed through rapid, punctuated events occurring circa 3300 to 3200 cal BP.
