Bioarchaeological investigation of ancient Maya violence and warfare in inland northwest Yucatan,Mexico

This study investigates evidence of changes and continuities in ancient Maya violence and warfare in inland northwest Yucatan, Mexico from the Middle Preclassic (600–300 BC) to the Postclassic (AD 1050–1542) through bioarchaeological analysis of cranial and projectile trauma. It is hypothesized that the frequency of violence increases before the Classic Maya collapse and remains high during the Postclassic period. It is also hypothesized that the flat, open terrain was conducive to warfare and resulted in higher trauma frequencies than in other parts of the Maya area. Results show that the frequency of cranial trauma decreases before the Classic collapse and increases in the Postclassic, partially matching the expected chronological trends. The frequency of cranial trauma does not differ significantly from other Maya regions but the pattern does: for all periods, males have more healed injuries than females and they are concentrated on the left side of the anterior of the skull. Some injuries appear to be from small points hafted in wooden clubs. In addition, projectile trauma is evident in a scapula with an embedded arrowhead tip, the first such case reported in a Maya skeleton. Overall, these results suggest greater reliance on open combat and less on raids in this region compared with other parts of the Maya area, possibly due to the flat, open terrain, though the identification of perimortem trauma in both women and men indicates surprise raids on settlements were also practiced.

The Collapse of the Classic Maya: A Case for the Role of Water Control

This article focuses on the role of water control in the emergence and demise of Classic Maya political power (c. C.E. 250-950), one that scholars have long underestimated. The scale of water control correlates with the degree of political power, reflected in three levels of Maya civic-ceremonial centers—regional, secondary, and minor. Such power derives from a complex relationship among center location, seasonal water supply, amount of agricultural land, and settlement density. Maya kings monopolized artificial reservoirs and other water sources during annual drought, providing the means to exact tribute from subjects. Climate change undermined the institution of rulership when existing ceremonies and technology failed to provide sufficient water. The collapse of rulers' power at regional centers in the Terminal Classic (c. C.E. 850-950) had differing impacts on smaller centers. Secondary and minor centers not heavily dependent on water control survived the drought and the collapse of regional centers. [Keywords: political power, water control, Classic Maya collapse]     

Assessing the impact of ancient Maya animal use

Tropical forest animals are at high risk worldwide as a result of over-exploitation and forest clearing. Zooarchaeological studies of animal use by the ancient Maya of the southern lowland regions of Guatemala, Honduras, Belize, and Mexico provide long-term historical information on animal populations under conditions of human population growth and climatic change that is valuable to both archaeology and conservation biology. In this paper, zooarchaeological data from 35 chronologically defined faunal sub-samples recovered from 25 ancient Maya archaeological sites are used to assess the effects of ancient hunting on animal populations of the Maya region between the Preclassic and Colonial periods (2000 BC–AD 1697). The variations in species abundance are used as a proxy for describing changes in ancient Maya hunting practices and hunted animal populations, interpreted on the basis of hunting efficiency models from foraging ecology. A significant reduction in the proportion of large mammals, particularly Odocoileus virginianus, in zooarchaeological assemblages between the Late Classic (AD 600–850) and Terminal Classic/Postclassic periods (AD 850–1519) suggest that over-hunting during the Late Classic may have led to a reduction in availability of these animals to the ancient Maya hunters in the later periods. This finding is discussed in relation to important social and environmental variations to evaluate the impact of hunting and other factors such as forest clearance and climate on ancient animal populations in the Maya region.     

Founding Amerindian mitochondrial DNA lineages in ancient Maya from Xcaret, Quintana Roo

Ancient DNA from the bone remains of 25 out of 28 pre-Columbian individuals from the Late Classic-Postclassic Maya site of Xcaret, Quintana Roo, was recovered, and mitochondrial DNA (mtDNA) was amplified by using the polymerase chain reaction. The presence of the four founding Amerindian mtDNA lineages was investigated by restriction analysis and by direct sequencing in selected individuals. The mtDNA lineages A, B, and C were found in this population. Eighty-four percent of the individuals were lineage A, whereas lineages B and C were present at low frequencies, 4% and 8%, respectively. Lineage D was absent from our sample. One individual did not possess any of the four lineages. Six skeletons out of 7 dated from the Late Classic period were haplotype A, whereas 11 skeletons out of 16 dated from the Postclassic period were also haplotype A. The distribution of mtDNA lineages in the Xcaret population contrasts sharply with that found in ancient Maya from Copán, which lack lineages A and B. On the other hand, our results resemble more closely the frequencies of mtDNA lineages found in contemporary Maya from the Yucatán Peninsula and in other Native American contemporary populations of Mesoamerican origin.     

The causes and consequences of deforestation among the prehistoric Maya

The collapse of the Classic Maya state is investigated from an ecological perspective. Settlement and palynological data from the Maya center of Copan, Honduras, are presented which indicate that substantial clearing of the upland pine forest had occurred prior to and during the abandonment of that urban center. A comparative use- rate analysis suggests that the increased clearing of pine was primarily caused by demands for domestic fuel wood by an expanding urban population. This forest mismanagement is directly linked to accelerated erosion rates which are considered primary elements in the collapse of the Maya state.     

Population structure of the Classic period Maya

This study examines the population structure of Classic period (A.D. 250-900) Maya populations through analysis of odontometric variation of 827 skeletons from 12 archaeological sites in Mexico, Guatemala, Belize, and Honduras. The hypothesis that isolation by distance characterized Classic period Maya population structure is tested using Relethford and Blangero's (Hum Biol 62 (1990) 5-25) approach to R matrix analysis for quantitative traits. These results provide important biological data for understanding ancient Maya population history, particularly the effects of the competing Tikal and Calakmul hegemonies on patterns of lowland Maya site interaction. An overall F(ST) of 0.018 is found for the Maya area, indicating little among-group variation for the Classic Maya sites tested. Principal coordinates plots derived from the R matrix analysis show little regional patterning in the data, though the geographic outliers of Kaminaljuyu and a pooled Pacific Coast sample did not cluster with the lowland Maya sites. Mantel tests comparing the biological distance matrix to a geographic distance matrix found no association between genetic and geographic distance. In the Relethford-Blangero analysis, most sites possess negative or near-zero residuals, indicating minimal extraregional gene flow. The exceptions were Barton Ramie, Kaminaljuyu, and Seibal. A scaled R matrix analysis clarifies that genetic drift is a consideration for understanding Classic Maya population structure. All results indicate that isolation by distance does not describe Classic period Maya population structure.     

黑龙江查哈阳农场石制品的剥片与修理技术

查哈阳农场位于黑龙江省齐齐哈尔市甘南县,地处松嫩平原西缘的嫩江右岸。本文以2018年在查哈阳农场太平湖管理区第八作业区东北的E2地点试掘的石制品为研究对象,从石核的剥片和石器修理的角度对石制品进行技术分析。石核、石片以及石器分析显示,E2地点存在两种剥片技术体系：一是简单剥片技术体系,该技术不存在剥片前对核体的预制过程,以片状石核、大量不规则的石片以及修理程度较低的石器为代表;二是系统剥片技术体系,该技术以剥离石叶（长石片）为最终目的,存在剥片前对核体“几何组织结构”的修型、预制现象,同时伴随台面的预制修理。E2地点的石制品技术分析,可为嫩江流域旧石器时代晚期石器工业面貌的揭示和技术变化的探讨提供新的材料与线索。     

CONTOURS OF AN ANTHROPOLOGY OF THE CHINESE STATE: POLITICAL STRUCTURE, AGENCY AND ECONOMIC DEVELOPMENT IN RURAL CHINA

Anthropologists have long been inclined to view China from the perspective of a state-society dichotomy. In this model, the inevitable consequence of economic reform is that – especially at the local level – the state must yield more and more of its power to entrepreneurs, foreign investors, non-state organizations, and local communities. Not only does this approach distort the role of the state in society, but by placing the state above and outside society it also excludes it from the anthropological gaze. This article proposes an anthropology of the Chinese state which does not merely view the state in society, but also investigates the state itself as society. Drawing on fieldwork in northeastern Yunnan province, I illustrate this general point by investigating the changing role of the local state in economic development. This agenda for an anthropology of the Chinese state resonates both with the recent 'reinvention' of the subfield of political anthropology with its focus on governmentality, policy, and rights, and with recent calls by political scientists for the development of an interdisciplinary anthropology of the developmental state.     

Ritual responses to drought: An examination of ritual expressions in Classic Maya written sources

Planting and rain-beckoning rituals are an extremely common way in which past and present human communities have confronted the risk of drought across a range of environments worldwide. In tropical environments, such ceremonies are particularly salient despite widespread assumptions that water supplies are unproblematic in such regions. We demonstrate for the first time that two common but previously under-appreciated Maya rituals are likely planting and rain-beckoning rituals preferentially performed at certain times of the year in close step with the rainy season and the Maya agricultural cycle. We also argue for considerable historical continuity between these Classic Maya ceremonies and later Maya community rituals still performed in times of uncertain weather conditions up to the present day across Guatemala, Belize, and eastern Mexico. During the Terminal Classic period (AD 800-900), the changing role played by ancient Maya drought-related rituals fits into a wider rhetorical shift observed in Maya texts away from the more characteristic focus on royal births, enthronements, marriages, and wars towards greater emphasis on the correct perpetuation of key ceremonies, and we argue that such changes are consistent with palaeoclimatic evidence for a period of diminished precipitation and recurrent drought.     

Carious lesions and maize consumption among the Prehispanic Maya: an analysis of a coastal community in northern Yucatan

Patterns of carious lesions were analyzed in the Classic period coastal Maya population of Xcambó, a salt production and administration center in northern Yucatan. To this end, the study investigated caries in the permanent dentitions of 163 adult skeletons, 23 from the Early Classic (AD 250-550) and 140 from the Late Classic period (AD 550-750), equally distributed between sexes. The archaeological and bioarchaeological evidence indicates a wealthy and socially homogeneous population dedicated to salt production and administration in the Early Classic that switched to pure administrative functions in the Late Classic. The results indicate an increase in caries from 7.4% and 21.2% (males and females respectively) from the Early Classic to 14.0% in males and 27.4% in females from the Late Classic period. The rate of caries in the Early and in the Late Classic phases of continuous occupation is not consistent with a simple interpretation of a heavier reliance on maize during the latter phase, characterized by a sedentary lifestyle, particularly for the male segment of the society now dedicated completely to the administration of the salt mines. Rather, the increase in caries rates in both sexes is best explained within a broader context of overall food habits, new cariogenic foods for both sexes, and the changes in lifestyle imposed by the increased socioeconomic role of the site. Our conclusions stress the limitations imposed by interpreting carious lesions solely in terms of single dietary components, such as maize consumption, without taking into account broader aspects of cultural and socioeconomic relevance.     

Kingship in the Late Preclassic Maya Lowlands: The Instruments and Places of Ritual Power

The Maya of Central America constitute the only truly literate pre-Columbian civilization. Analysis of ancient Maya hieroglyphic texts and accompanying images dating from the Classic period (A.D. 200–900) documents the presence of a central and pervasive institution of governance: ahaw. The material symbol systems of the Lowland Maya of the protoliterate Late Preclassic period (350 B.C.-A.D. 100), as evinced in monumental decorated buildings and in portable art, suggest that these Maya innovated ahaw, the institution of kingship. The authority of ahaw rested upon direct descent and spiritual communion with the ancestors of all Maya, the Ancestral Heroes. Along with noble lineage, ahaw claimed charismatic power through the performance of shamanistic ritual. The Late Preclassic antecedents of the shamanistic parameters of ahaw are discussed in light of Classic and Postclassic ritual expressions.     

Like Water for Chocolate: Feasting and Political Ritual among the Late Classic Maya at Xunantunich, Belize

Subtle differences in the context of feasting and manners of food consumption can point to underlying levels of civil and social competition in state-level societies. Haute cuisine and high styles of dining are characteristic of societies with fully developed civil and social hierarchies such as Renaissance Europe and the Postclassic Aztec. Competitive yet socially circumscribed political and social organizations such as the Classic lowland Maya may have prepared elaborate diacritical meals that marked status, but the nature of feasting remained essentially patriarchal. Ancient Maya feasting is recognizable through archaeologically discernible pottery vessel forms that were used to serve festival fare such as tamales and chocolate. Comparison of ceramic assemblages across civic and household contexts at the site of Xunantunich, Belize, demonstrates that drinking chocolate, more so than eating tamales, served as a symbolic cue that established the political significance of events among the Classic Maya.

Sacred Giants: Depiction of Bombacoideae on Maya Ceramics in Mexico,Guatemala, and Belize

Sacred Giants: Depiction of the Malvaceae Subfamily Bombacoideae on Maya Ceramics in Mexico, Guatemala, and Belize This study categorized and identified plants depicted on Maya ceramics from the Classic Period (250 a.d.–900 a.d.). We chose art objects with a predominance of iconographic images of Malvaceae subfamily Bombacoideae, which are easily identified morphologically and have culinary, medicinal, ceremonial, economic, and cosmological significance to the Maya. Among ten species of Bombacoideae native to the Southern Lowlands region of Central America (Belize, parts of Guatemala, and Mexico), the Maya utilized at least six, which also have Maya names. We observed four or five bombacoid species depicted on Maya ceramics; most images were identifiable to genus. Burial urns and incensarios (incense burners) commonly had images of trunk spines of Ceiba pentandra, the Maya “World Tree.” Flowers of Pseudobombax ellipticum, a plant used to make ceremonial beverages, were most similar to floral images portrayed on vessels, bowls, and plates, although the morphologically similar flowers of Pachira aquatica may also be depicted. Plants representing Quararibea funebris or Q. guatemalteca, which were used during preparation of cacao beverages, were discernable on drinking vessels.     

Cloth, Gender, Continuity, and Change: Fabricating Unity in Anthropology

In this article, I compare backstrap-loom weaving in three cultural contexts: the ancient Maya, the ancient Aztecs, and 20th-century Mesoamerica. Although continuities are present, important differences exist in the ways that weaving was situated historically. Among the Classic Maya, weaving defined class; in Aztec Mexico, weaving defined gender; and in 20th-century Mesoamerica, weaving defined ethnicity. A comparison of these cases suggests that historical study is a useful tool for both archaeologists and ethnographers. It promotes recognition of the diversity of practice and belief in ancient societies. It helps to define the scope of contemporary ethnographic study. It combats cultural essentialism and injects agency into our accounts. It enables us to acknowledge both the rich heritage of indigenous peoples and the fact of culture change. Comparative historical study provides a strong rationale for the continued association of archaeology and cultural anthropology as parts of a wider anthropological whole.     

Genomic insights on the ethno-history of the Maya and the ‘Ladinos’ from Guatemala

Background

Guatemala is a multiethnic and multilingual country located in Central America. The main population groups separate ‘Ladinos’ (mixed Native American-African-Spanish), and Native indigenous people of Maya descent. Among the present-day Guatemalan Maya, there are more than 20 different ethnic groups separated by different languages and cultures. Genetic variation of these communities still remains largely unexplored. The principal aim of this study is to explore the genetic variability of the Maya and ‘Ladinos’ from Guatemala by means of uniparental and ancestry informative markers (AIMs).

Results

Analyses of uniparental genetic markers indicate that Maya have a dominant Native American ancestry (mitochondrial DNA [mtDNA]: 100%; Y-chromosome: 94%). ‘Ladino’, however, show a clear gender-bias as indicated by the large European ancestry observed in the Y-chromosome (75%) compared to the mtDNA (0%). Autosomal polymorphisms (AIMs) also mirror this marked gender-bias: (i) Native American ancestry: 92% for the Maya vs. 55% for the ‘Ladino’, and (ii) European ancestry: 8% for the Maya vs. 41% for the ‘Ladino’. In addition, the impact of the Trans-Atlantic slave trade on the present-day Guatemalan population is very low (and only occurs in the ‘Ladino’; mtDNA: 9%; AIMs: 4%), in part mirroring the fact that Guatemala has a predominant orientation to the Pacific Ocean instead of a Caribbean one. Sequencing of entire Guatemalan mitogenomes has led to improved Native American phylogeny via the addition of new haplogroups that are mainly observed in Mesoamerica and/or the North of South America.

Conclusions

The data reveal the existence of a fluid gene flow in the Mesoamerican area and a predominant unidirectional flow towards South America, most likely occurring during the Pre-Classic (1800 BC-200 AD) and the Classic (200–1000 AD) Eras of the Mesoamerican chronology, coinciding with development of the most distinctive and advanced Mesoamerican civilization, the Maya. Phylogenetic features of mtDNA data also suggest a demographic scenario that is compatible with moderate local endogamy and isolation in the Maya combined with episodes of gene exchange between ethnic groups, suggesting an ethno-genesis in the Guatemalan Maya that is recent and supported on a cultural rather than a biological basis.

A Zooarchaeological Test for Dietary Resource Depression at the End of the Classic Period in the Petexbatun,Guatemala

Zooarchaeological analyses of animal remains from the Petexbatun sites in the Guatemalan lowlands provide proxy evidence to test a hypothesis of dietary insufficiency during the Maya “collapse.” Ecological foraging theory and resource depression models are used to interpret animal use patterns before and after the disintegration of the Petexbatun polity at the end of the Late Classic period (around a.d. 800). Environmental failure models of the Maya “collapse” at the end of the Late Classic imply that a dietary insufficiency, and particularly a lack of animal resources, was associated with the political and social transitions of this period. However, the results of this zooarchaeological study do not support this hypothesis and point instead to very limited early reductions of only highest-ranked dietary species. The lack of evidence for specific resource depression associated directly with the period of political collapse does not support a model of environmental failure during political disintegration in the Petexbatun. Correlations are found between animal use patterns and the specifics of site size and periods of peak political activity, suggesting that small-scale resource depressions might have resulted at some sites during early periods of human population growth, site expansion, and increasing political activity.
