AbstractCore MAN015 from Pacific coastal Guatemala contains sediments accumulated in a mangrove setting over the past 6500 yr. Chemical, pollen, and phytolith data, which indicate conditions of estuarine deposition and terrigenous inputs from adjacent dry land, document Holocene climate variability that parallels the Maya lowlands and other New World tropical locations. Human population history in this region may be driven partly by climate variation: sedentary human populations spread rapidly through the estuarine zone of the lower coast during a dry and variable 4th millennium B.P. Population growth and cultural florescence during a long, relatively moist period (2800–1200 B.P.) ended around 1200 B.P., a drying event that coincided with the Classic Maya collapse.

Terminal Classic Period

Magnetic, palynological, and paleoecological data indicate that in the Río de la Pasión drainage, one of the most thoroughly investigated areas of the southern Maya lowlands, a refugee population remained in the Laguna Las Pozas basin long after the Classic Maya collapse and the Terminal Classic period, previously identified by archaeologists as eras of near-total regional abandonment. During the Early Postclassic period, ca. A. D. 900 to 1200, agriculturalists colonized and deforested the Laguna Las Pozas basin for agriculture while adjacent, abandoned terrain was undergoing reforestation. After discussing the archaeological utility of magnetic analyses, we conclude that following the Maya collapse, some refugee populations migrated to geographically marginal non-degraded landscapes within the southern lowlands not previously occupied by the Classic Maya.

During the past few decades, many scholars have studied the various demographic consequences of European overseas expansion. One focus of attention has been the fatal impact of European expansion on the native populations of the New World. Before contact with Europeans, the native populations of the Americas, Australia, and the Pacific were generally free of infectious diseases, and so lacked immunity to diseases such as smallpox, measles, and influenza, which were introduced by Europeans. A second focus of attention has been the mortality among Europeans when they went overseas and encountered new diseases, such as malaria, yellow fever, and cholera, to which they had no immunity. And a third focus of attention has been the mortality among various African, Asian, and Pacific Islander labourers when they were procured as slaves or indentured servants for work on European plantations in various parts of the world.

The past decades have witnessed major advancements in our understanding of Classic Maya political history, particularly geopolitical dynamics centered on hegemonic states. Yet there has been only halting progress toward historically based archaeological research focusing on the political, social, and economic impacts of political domination and subordination. To address this deficiency, I examine changes in settlement patterns and ceramic sphere affiliation in the Río Champotón drainage within broader historical and geopolitical developments. In this region, the end of the Classic period is characterized by dramatic changes in ceramic links, with a shift from inland-focused traditions to the incorporation within a coastal ceramic sphere—the Canbalam sphere—that linked maritime trade centers between northwest Yucatán and coastal Tabasco. These transitions were embedded within major reorientations in regional settlement patterns and broader geopolitical dynamics centering on the expansion and dissolution of the Kanu’l state, or Snake Dynasty. Following the decline of the Snake Dynasty of Calakmul, communities in central Campeche forged new political and economic ties with emergent centers along the Gulf Coast and the northern Maya Lowlands. The results of this study demonstrate the transformative nature of hegemonic interpolity relationships and highlight the potential for new avenues of conjunctive research combining historical and archaeological data sources.

ABSTRACTPopulation genetic studies suggest that most amino-acid changing mutations are deleterious. Such mutations are of tremendous interest in human population genetics as they are important for the evolutionary process and may contribute risk to common disease. Genomic studies over the past 5 years have documented differences across populations in the number of heterozygous deleterious genotypes, numbers of homozygous derived deleterious genotypes, number of deleterious segregating sites and proportion of sites that are potentially deleterious. These differences have been attributed to population history affecting the ability of natural selection to remove deleterious variants from the population. However, recent studies have suggested that the genetic load may not differ across populations, and that the efficacy of natural selection has not differed across human populations. Here I show that these observations are not incompatible with each other and that the apparent differences are due to examining different features of the genetic data and differing definitions of terms.

ABSTRACT Deposits linked to abandonment have been widely recorded across the Maya lowlands, associated with the final activities occurring in ceremonial areas of Classic Maya centers. Various models have been applied to explain the activities that lie behind the formation of these contexts, including those linked to rapid abandonment (e.g., warfare) and others focused on more protracted events (termination rituals, and/or pilgrimages). Here, we assess Bayesian models for three chronological scenarios of varying tempo to explain the formation of peri-abandonment deposits at Baking Pot, Belize. Using stratigraphic information from these deposits, hieroglyphic dates recovered on artifacts, and direct dates on human skeletal remains and faunal remains from distinct layers in three deposits in Group B at Baking Pot, we identify multiple depositional events that spanned the eighth to ninth centuries AD. These results suggest that the processes associated with the breakdown of institutionalized rulership and its command of labor to construct and maintain ceremonial spaces were protracted at Baking Pot, with evidence for the final depositional activity dated to the mid-to-late ninth century. This interval of deposition was temporally distinct from the earlier deposition(s) in the eighth century. Together, these data offer a detailed view of the end of the Classic period at Baking Pot, in which the ceremonial spaces of the site slowly fell into disuse over a period of more than a century.

AbstractThe Pacific has often been invisible in global histories written in the UK. Yet it has consistently been a site for contemplating the past and the future, even among Britons cast on its shores. In this lecture, I reconsider a critical moment of globalisation and empire, the ‘age of revolutions’ at the end of the eighteenth century and the start of the nineteenth century, by journeying with European voyagers to the Pacific Ocean. The lecture will point to what this age meant for Pacific islanders, in social, political and cultural terms. It works with a definition of the Pacific's age of revolutions as a surge of indigeneity met by a counter-revolutionary imperialism. What was involved in undertaking a European voyage changed in this era, even as one important expedition was interrupted by news from revolutionary Europe. Yet more fundamentally vocabularies and practices of monarchy were consolidated by islanders across the Pacific. This was followed by the outworkings of counter-revolutionary imperialism through agreements of alliance and alleged cessation. Such an argument allows me, for instance, to place the 1806 wreck of the Port-au-Prince within the Pacific's age of revolutions. This was an English ship used to raid French and Spanish targets in the Pacific, but which was stripped of its guns, iron, gunpowder and carronades by Tongans. To chart the trajectory from revolution and islander agency on to violence and empire is to appreciate the unsettled paths that gave rise to our modern world. This view foregrounds people who inhabited and travelled through the earth's oceanic frontiers. It is a global history from a specific place in the oceanic south, on the opposite side of the planet to Europe.

Human populations have been known to develop complex relationships with large carnivore species throughout time, with evidence of both competition and collaboration to obtain resources throughout the Pleistocene. From this perspective, many archaeological and palaeontological sites present evidence of carnivore modifications to bone. In response to this, specialists in the study of microscopic bone surface modifications have resorted to the use of 3D modeling and data science techniques for the inspection of these elements, reaching novel limits for the discerning of carnivore agencies. The present research analyzes the tooth mark variability produced by multiple Iberian wolf individuals, with the aim of studying how captivity may affect the nature of tooth marks left on bone. In addition to this, four different populations of both wild and captive Iberian wolves are also compared for a more in-depth comparison of intra-species variability. This research statistically shows that large canid tooth pits are the least affected by captivity, while tooth scores appear more superficial when produced by captive wolves. The superficial nature of captive wolf tooth scores is additionally seen to correlate with other metric features, thus influencing overall mark morphologies. In light of this, the present study opens a new dialogue on the reasons behind this, advising caution when using tooth scores for carnivore identification and contemplating how elements such as stress may be affecting the wolves under study.

Maya Collapse

Several lines of archaeological evidence are presented in this paper to suggest the existence of class warfare among the Classic Maya and of issues that historically have been associated with class conflict. This evidence indicates that class warfare may have halted the rule of the monument-producing, or Classic, elites and precipitated the depopulation of the lowland area. The theory is evaluated quantitatively by testing for time-related mathematical patterns that have been found to characterize large-scale conflicts in historical societies. The information used in the evaluation involves the time series data on the duration of rule by Classic elites as inferred from the production of monuments with Long Count dates at a sample of 82 ceremonial centers. The analyses confirm that the Maya data do exhibit the temporal and geographical patterns predicted from the class conflict explanation of the Classic Maya collapse. Alternative predictions from the other theories are considered but generally not found to be supported by these data.

To determine the pattern of selective utilization of animal species by prehistoric human populations, it is first necessary to quantify the relative importance of species of animals in the diet of prehistoric human groups through analysis of archaeologically recovered faunal samples. These values are then compared with estimates of the relative availability of different species of animals in the environment. Such estimates of the relative availability of animal species in prehistoric habitat situations, usually quantified in terms of biomass, are obtained by projecting data from modern analog situations into the past. When attempting to reconstruct prehistoric biotic communities in this manner, it is important to be aware of a number of possible sources of bias and to evaluate and apply modern wildlife data according to a set of interrelated principles. Sources of bias and criteria for selecting modern wildlife analog data are discussed.
