Cacao consumption during the 8th century at Alkali Ridge,southeastern Utah

Theobroma cacao was detected in the ceramic assemblage at the 8th century Site 13, Alkali Ridge, southeastern Utah. The presence of this Mesoamerican beverage during the Pueblo I period is the earliest reported use of cacao in the northern American Southwest, coming centuries earlier than the recently documented Pueblo II consumption of cacao in cylinder jars, sharp-shouldered pitchers and shallow bowls at Pueblo Bonito, Chaco Canyon. Analogous to the situation at Chaco, cacao was found at Site 13 in a new vessel form decorated with a distinctive design system that contrasted markedly with designs and vessel forms in the local black-on-white ceramic assemblage. We postulate that Abajo R/O at Site 13 represents a ceramic tradition brought by one of the many groups moving into the northern Southwest. The detection of cacao in their ceramic vessels represents new evidence for the migration model that for centuries brought people with Mesoamerican beliefs, ritual practices and a new subsistence lifeway into the American Southwest.     

Soils and the location of Cacao orchards at a Maya site in Western Belize

Cacao was one of the most important crops of the lowland Maya. Ethnohistoric sources document that the Postclassic-Colonial Period Maya settlement of Tipu in western Belize was an important cacao-growing center, yet evidence of where the cacao was grown is not apparent. We analysed the suitability of floodplain, terrace, and bedrock soils for cacao cultivation. Our results indicate that the soils most likely to have been used for cacao growth were those on the modern floodplain of the Macal River, based on their suitable physical and chemical properties. In addition, buried stone walls of Late Classic or Postclassic age that may have been used for field demarcation were found on the floodplain, suggesting that this geomorphic surface was also utilized well before the time of Spanish contact, possibly for intensive agriculture.     

Recent research in west Mexican archaeology

The last decade has seen the greatest increase in archaeological research in western Mexico since the 1940s. Unlike previously heralded renewals, this one is accompanied by widespread skepticism of the dominant culture-historical paradigm linking west Mexico to the rest of Mesoamerica, to the American Southwest, and to South America. Current research offers substantive new data and interpretations bearing on issues such as the definition of Mesoamerica, the role of South American long distance contacts, the human ecology of highland lakes, the role of river systems in Mesoamerican prehistory, and the nature/role of prehispanic elite exchanges.     

X-ray fluorescence analysis and intra-island exchange in the Society Island archipelago (Central Eastern Polynesia)

We apply X-ray fluorescence (XRF) geochemical analysis to a collection of 'Opunohu Valley lithic artifacts from Mo'orea island to investigate the local scale of raw material procurement, adze production, use, and exchange within the Society Island archipelago. We use these data to document the distribution of non-local versus local volcanic artifacts in 'Opunohu Valley house sites, ritual sites, and specialized sites, as a means for establishing intra-site production and consumption patterns, and access to exotic, possibly superior, stone resources, and how these two themes correlate with site function or household wealth and status. Overall, 30% of the artifacts analyzed via WDXRF derive from non-local sources, notably two other islands in the archipelago outside of the political boundaries of Moorean chiefdoms. Our case study thus provides the first direct material evidence of intra-archipelago trade and exchange in the Society Islands. Intra-archipelago trade in adzes was certainly in place by as early as A.D. 1350, if not earlier, and continued up until the time of European contact. In addition, our analyses have identified a local adze production locale in the Afareaitu district of Mo'orea island. The patterns of local versus non-local adze production and exchange strongly suggest that dual interaction spheres were involved. The correlation between adzes and adze-related debris produced from off-island sources and sites with specialized use, which were often reserved for the social, ritual, and political elites in Ma'ohi society suggests that some of the exotic adzes derived from gift exchange between Mo'orea and ruling elites in Tahiti and the Leeward Islands. These adzes from afar would have solidified socio-political and ideological alliances between elites in the Windward and Leeward sectors of the archipelago.     

Museum salvage: A case study of Mesoamerican artifacts in museum collections and on the antiquities market

Abstract

Museum salvage refers to critical studies of museum collections with little or no provenience information that seek to glean useful archaeological information from these artifacts and examine the nature of their origins and possible connections to the illicit antiquities trade and the art market. Our case study focuses on artifacts from Mesoamerica and objects from the ancient capital of Teotihuacan in particular. We take a multi-scalar approach, including a quantitative analysis of Sotheby’s auction records for Mesoamerican items from 1966 to 2010, a survey of Teotihuacan attributed items in U.S. museums, and a more detailed examination of Teotihuacan-style artifacts in the Denver Museum of Nature & Science collections. The study tracks and attempts to explain diachronic patterns in the Mesoamerican antiquities trade, connections to museum collecting practices, and looting behavior. The study illustrates the potential benefits of museum salvage, while also revealing the clear limitations of research on poorly documented archaeological material.     

Isotopic investigation of pre-Hispanic macaw breeding in Northwest Mexico

The pre-Hispanic settlement of Paquimé (ca. 1200–1450 AD) lay outside of urban Mesoamerica in arid northern Chihuahua, Mexico, yet the excavated remains of 322 scarlet macaws, tropical parrots whose northernmost habitat is 500 km to the south, suggest that Paquimé had relationships with distant communities. Here, carbon and oxygen stable isotope analysis of 30 macaw bones determines whether the Paquimeños actively bred these parrots or traded with Mesoamerican groups to obtain the birds. The δ¹³C values indicate that the macaws ate a diet of C₄ plants, foods that were unavailable to wild macaws. In addition, δ¹⁸O data suggest that the majority of the macaws spent their entire lives at Paquimé. We conclude that the ancient Paquimeños were in fact breeding scarlet macaws, although one bone with δ¹⁸O values outside the local range suggests that the breeders also maintained exchange ties with the source areas of the birds. By confirming that Paquimeños implemented a system of local macaw reproduction outside the Mesoamerican region itself, this analysis provides new evidence about the economic and ideological interdependence of pre-Hispanic societies in the Americas. It is also suggestive of the pre-industrial capabilities of humans to extend the natural ranges of animal species.     

Eggshell and the archaeological record: new insights into turkey husbandry in the American Southwest

Eggshell in the archaeological record has interpretive potential beyond simple species identification. Structural features of eggshell itself indicate the degree of development of the embryo. Using a scanning electron microscope, a reference collection of modern eggshell characteristics has been produced that can be used for species determination and for the assessment of embryo development of prehistoric eggshell. We apply this technique to a sample of prehistoric eggshell from northwestern New Mexico and conclude that purposeful breeding of captive turkey populations is present during the 12th century AD. These preliminary results suggest a behavioral shift in turkey husbandry, concomitant with the well documented phenomenon of intensified turkey utilization after about AD 1100 in the American Southwest.     

Higher ground: The archaeology of North American platform mounds

Platform mounds, as forms of monumental architecture, have long been central to inquiries into Native American social complexity. The archaeological literature produced over the last 5 years that pertains to North American platform mounds in the Southeast and Southwest is reviewed. Chronologies, forms, and functions of platform mounds are summarized. There are similarities in the platform mound characteristics and construction sequences found in both regions. It is proposed that these characteristics reflect similar social processes of integration and differentiation.     

The Uncertain Origins of Mesoamerican Turkey Domestication

The turkey (Meleagris gallopavo) is the only domesticated vertebrate to originate from North America. Accurate reconstructions of the timing, location, and process of its domestication are thus critical for understanding the domestication process in the ancient Americas. A substantial amount of recent research has been devoted to understanding turkey domestication in the American Southwest, but comparatively little research has been conducted on the subject in Mesoamerica, despite the fact that all modern domestic turkeys descend from birds originally domesticated in Mexico during pre-colonial times. To address this disparity, we have conducted a review of the available literature on early turkeys in the archaeological record of Mesoamerica. We evaluate the evidence in terms of its accuracy and use this evaluation as a stepping off point for suggesting potential avenues of future research. Although the lack of available data from Mesoamerica currently precludes detailed cross-cultural comparisons, we briefly compare the origins and intensification of turkey rearing in Mesoamerica with the American Southwest to generate more dialogue among researchers independently studying the topic in these two distinct but interconnected cultural regions.     

The relationship of the Mimbres to other southwestern and Mexican populations

Previous aDNA research in the Southwest provides a framework to understand the Mimbres population which maintains a unique identity in the archeology of the desert Southwest of North America. Both the mitochondrial DNA (mtDNA) haplogroups and haplotypes of a sample of 46 Mimbres individuals were identified from skeletal remains and compared to those of other ancient and modern populations in the American Southwest and Mexico. The haplogroup frequency distribution of the Mimbres resembles that of other Southwestern populations, suggesting a close relationship between the Mimbres and the neighboring populations and population continuity for a long period of time. However, their relatively low frequency of haplogroup A (11% n = 5) is consistent with a clinal distribution of haplogroup A from Mesoamerica to the Southwest. Moreover, unlike other Southwestern populations, the Mimbres share haplotypes with populations to the south, such as the Cora, Huichol, and Nahua, suggesting gene-flow from Mesoamerica. Here we discuss this data in light of the origin of the Mimbres population and their relationship to other Southwestern and Mexican populations.     

Lay-Religious Associations, Urban Identities, and Urban Space in Eighteenth-Century Milan

Religious life was integral to the social and political organization of eighteenth-century Milan. The composition and character of lay-religious activities reflect not only official hierarchies within the city but also unofficial bonds and identities, such as those of neighbourhood. They reveal the multiple identities of neighbourhood, parish, trade and family, but equally the tensions between collective forms of piety and the new religious values and aesthetic adopted by the Milanese elites during the late Enlightenment.     

Free Trade Agreements and the Neo-Liberal Economic Paradigm: Economic,Ecological, and Moral Consequences

Abstract

Since signing and implementing the North American Free Trade Agreement (FTA) in the early 1990s, the United States has pursued other free trade agreements with nations in Latin America and Asia. The premise undergirding FTAs is that trade liberalization within the neo-liberal global economy produces economic growth and development among all parties, and reduces poverty in poor nations. We examine arguments of proponents of free trade and the neo-liberal economy— particularly those of Martin Wolf, author of Why Globalization Works— to test these claims. We explore alternatives that center on norms of ecological sustainability and social justice, holding these two as inseparable. The central moral question of how to achieve needed socioeconomic development in the Global South in ways that are both ecologically sustainable and socially just frames our analysis. We conclude by proposing five principles for an alternative, more sustainable and equitable economic paradigm.     

Sourcing ceramics with portable XRF spectrometers? A comparison with INAA using Mimbres pottery from the American Southwest

Seventy-five intact Mimbres and Jornada pottery sherds from the American Southwest were analyzed by portable XRF and instrumental neutron activation analysis (INAA). Examination of the data demonstrates that INAA and portable XRF results for elements common to both analyses can be used to construct similar compositional groups. When individual compositional groups are compared to one another, it is apparent that unambiguous separation of compositional groups is challenging by portable XRF given (1) the limited number of key discriminating elements that can be measured relative to INAA, and (2) the relative analytical precision and accuracy of portable XRF for measurements of intact heterogeneous ceramics. We conclude that sourcing intact ceramics by portable XRF is challenging and that bulk analytical measurements, such as INAA, remain a better approach for sourcing archaeological pottery.     

Intermarriage,Technological Diffusion,and Boundary Objects in the U.S. Southwest

This article draws upon ethnographic accounts of female potters’ movement and intermarriage into multi-ethnic Pueblo communities in the U.S. Southwest to illustrate how marriage networks created opportunities for innovation through the production, distribution, and consumption of boundary objects. These objects did not define boundaries but facilitated boundary crossing or bridging by potters. I argue that the concept of boundary objects is more useful than hybridity for understanding the processes of culture contact and material culture diffusion. Archaeological evidence for late twelfth through thirteenth century migrations from the Four Corners to the southern Colorado Plateau is used to make a case for a high degree of intermarriage and post-marital movement of women. Such patrilocality challenges normative views of post-marital residence, including those employed by early ceramic sociologists working in the same area of the Southwest and even at the same sites. The case that I discuss provides a contrast to other Southwest examples in which conformist transmission was more common, and helps to solve a paradox in explanations of the Southwest Pueblo Sprachbund. I conclude that the concept of boundary objects complements formal social network approaches in archaeology by bringing out the active role of objects in linking social actors.     

Cultural Effects on Phenetic Distances Among Postclassic Mexican and Southwest United States Populations

The Southwest United States (US) and Mesoamerica are often thought of as disparate regional networks separated by Northern Mexico. Chaco Canyon in the Southwest US, Tlatelolco in Central Mexico and Casas Grandes in Northern Mexico, all had large inter‐regional trade centres that economically connected these networks. This study investigated how factors such as geographic distance, shared migration history, trade and political interaction affected biological relationships and population affinities among sites in Mexico and in Southwest US during the Postclassic period (ad 900 ~ 1520). Distances based on cultural and geographic variables derived from archaeological and ethnohistoric data were compared with phenetic distances obtained from dental morphological traits. The results of Mantel tests show trade (corr = 0.441, p = 0.005), shared migration history (corr = 0.496, p = 0.004) and geographic distance (corr = 0.304, p = 0.02) are significantly correlated with phenetic distances, whereas political interaction (corr = 0.157, p = 0.133) is not. Partial Mantel tests show trade (corr = 0.223, p = 0.049) and shared migration history (corr = 0.493, p = 0.003) remain significant when controlling for similarities with geographic distance, although the correlation for trade and phenetic distance is lowered. Geographic distance is not significant when similarities with trade (corr = 0.067, p = 0.681) and shared migration history (corr = 0.148, p = 0.127) are controlled. These results highlight the importance of economic relationships and shared migration history across geographic regions in interpreting biological relationships among contemporaneous populations in prehistoric Mexico and the Southwest US.

Oxygen isotopes in cellulose identify source water for archaeological maize in the American Southwest

Maize (Zea mays) was a primary food crop for aboriginal societies of the arid American Southwest. Water used for maize production in these arid zones could have come from precipitation and runoff during the summer monsoon, from perennial streams and springs, or from stored soil water fed by snowmelt. The oxygen stable isotope ratio (δ¹⁸O) of summer and winter precipitation on the Colorado Plateau naturally differ by more than 10‰ providing a powerful tool for distinguishing winter- from summer-derived water sources used in cultivation of maize. We investigated whether variation in δ¹⁸O of potential source waters is preserved in the δ¹⁸O of cellulose (δ¹⁸O_cellulose) of maize cobs by growing four aboriginal and one modern maize variety in pots irrigated with water of known δ¹⁸O composition. The δ¹⁸O_cellulose values of cobs ranged from 26.8 to 36.4‰ (averaged within varieties) and were highly correlated with δ¹⁸O values of the source irrigation water (−15.8 to −8.2‰). Cob δ¹⁸O_cellulose from five archaeological sites on the Colorado Plateau in southeastern Utah ranged from 27.3 to 34.6‰, closely matching the range of values observed in experimental plants. A δ¹⁸O_cellulose model developed originally for tree rings was parameterized and applied to the archaeological maize cobs. The model indicated that monsoonal precipitation accounted for 0–20% of the moisture for archaeological cob samples from a site adjacent to a perennial stream and 43–98% for samples from an upland site, more distant from a perennial water source. These results reveal the potential for using δ¹⁸O_cellulose to investigate prehistoric irrigation practices and source water used for maize production in the American Southwest.     

Lithic Production and Consumption Patterns from the Great Platform at Late Postclassic (A.D. 1350–1525) Tzintzuntzan,Mexico

Late Postclassic period (a.d. 1350–1525) Tarascan economic activities often included higher degrees of political involvement and territorial control compared with other ancient Mesoamerican societies. Here I examine Tarascan obsidian economies through an analysis of lithic production and consumption patterns from structures excavated on and near the Great Platform at the imperial capital of Tzintzuntzan. Four spatially distinct patterns are evident. Great Platform residents used high-quality obsidian blades as ceremonial items or burial offerings and scrapers for craft production. Lower elite residents of Structure F, outside the Great Platform, produced their own blade tools and consumed a higher percentage of green obsidian than residents of the Great Platform. Excavations at Yacata 3 recovered bifacial arrowheads and obsidian bloodletters associated with disturbed offerings. The spatial distributions of lapidary preforms and highly polished fragments combined with accounts from the Relación de Michoacán (a.d. 1541) suggest that lower elites produced obsidian jewelry near the Great Platform.     

The origins of pottery as a practical domestic technology: Evidence from the middle Queen Creek area, Arizona

The site of Finch Camp in the middle Queen Creek area of Arizona, southeast of Phoenix, has produced some of the earliest evidence of utilitarian pottery use in the US Southwest. Using multiple lines of evidence from vessel morphology, surface alteration, and minute fatty acid residues in vessel walls, I evaluate the nascent function of the earliest vessels (mostly neckless jars, or tecomates) and infer a diachronic process of functional expansion from about 350 B.C.-A.D. 400. This evidence provides robust evidence for evaluating various theoretical models of pottery origins. I argue that utilitarian pottery was initially adopted in connection with the intensification of small particulate plant foods (e.g., seeds, grains) and increasing household-level control over resources. Further, vessel functions may have expanded during the early centuries A.D. in response to women’s task-scheduling conflicts stemming from increasing residential stability and growing reliance on low-level horticulture.     

Recent trends in the archaeology of the southeastern United States

The archaeological literature pertaining to the southeastern United States is examined for the 5-year period between 1988 and 1992 inclusive. Research traditions identified in an earlier article by Patty Jo Watson (Southeastern Archaeology 9: 43–54, 1990) as characteristic of the Southeast in the previous half-century are considered in light of recent contributions. Topics examined include Mesoamerican connections, trade, pottery typology, historical archaeology, subsistence studies, bioarchaeology, and lithic artifact research.     

Early Olmec obsidian trade and economic organization at San Lorenzo

The Olmec were the first complex society to develop in Mesoamerica between 1800 and 600 cal B.C. The earliest large Olmec center during this period was the archaeological site of San Lorenzo which emerged as Mesoamerica's first large ritual and political center between 1400 and 1000 cal B.C. San Lorenzo's growth as a prominent center included the development of long distance trade relationships with adjacent areas of Guatemala and highland Mexico. High precision chemical analysis of obsidian imported for use in the fabrication of cutting tools is used to reconstruct the growth, size and extent of San Lorenzo's interregional exchange networks with areas of Mexico and Guatemala where obsidian occurs as raw material. A total of 852 obsidian artifacts were analyzed to reconstruct changes in obsidian procurement between 1800 and 800 cal B.C. This represents one of the largest samples of sourced obsidian from a Mesoamerican site and it provides a comprehensive picture for the development of interregional trade networks for Mesoamerica's first large Olmec center.
