Triumph Of The Commons: Sustainable Community Practices On Rapa Nui (Easter Island), Robert J. Dinapoli, Carl P. Lipo, Terry L. Hunt

Anthropology Faculty Scholarship

The history of Rapa Nui (Easter Island) has long been framed as a parable for how societies can fail catastrophically due to the selfish actions of individuals and a failure to wisely manage common-pool resources. While originating in the interpretations made by 18th-century visitors to the island, 20th-century scholars recast this narrative as a “tragedy of the commons,” assuming that past populations were unsustainable and selfishly overexploited the limited resources on the island. This narrative, however, is now at odds with a range of archaeological, ethnohistoric, and environmental evidence. Here, we argue that while Rapa Nui did experience large-scale deforestation …

Deep Learning Reveals Extent Of Archaic Native American Shell-Ring Building Practices, Dylan Davis, Gino Capsari, Carl P. Lipo, Matthew Sanger

Anthropology Faculty Scholarship

In the mid-Holocene (5000 - 3000 cal B.P.), Native American groups constructed shell rings, a type of circular midden, in coastal areas of the American Southeast. These deposits provide important insights into Native American socioeconomic organization but are also quite rare: only about 50 such rings have been documented to date. Recent work using automated LiDAR analysis demonstrates that many more shell rings likely exist than are currently recorded in state archaeological databases. Here, we use deep learning, a form of machine intelligence, to detect shell ring deposits and identify their geographic range in LiDAR data from South Carolina. We …

Approximate Bayesian Computation Of Radiocarbon And Paleoenvironmental Record Shows Population Resilience On Rapa Nui (Easter Island), Robert J. Dinapoli, Enrico Crema, Timothy Reith, Carl P. Lipo, Terry L. Hunt

Anthropology Faculty Scholarship

Examining how past human populations responded to environmental and climatic changes is a central focus of the historical sciences. The use of summed probability distributions (SPD) of radiocarbon dates as a proxy for estimating relative population sizes provides a widely applicable method in this research area. Paleodemographic reconstructions and modeling with SPDs, however, are stymied by a lack of accepted methods for model fitting, tools for assessing the demographic impact of environmental or climatic variables, and a means for formal multi-model comparison. These deficiencies severely limit our ability to reliably resolve crucial questions of past human-environment interactions. We propose a …

Dataset For Faunal Analyses Of Biry House Food Remains, Castroville, Tx, Kathryn Maupin

Anthropology Datasets

In 2013, Van Dyke excavated a historic residence located at 309^th Paris Street in Castroville, Texas. Beginning in 1844, the house was occupied by the families that had immigrated from the Alsace region of France. Preliminary analyses of the faunal recovered from a lime slaking pit suggested that over the course of the home’s residence, family members incorporate wild taxa into their diet in addition to their traditional Alsatian foodstuffs. Expanded analyses of the faunal remains from additional features provide additional evidence that the diet of the residents slowly transitioned away from a strict Alsatian diet and eventually included …

Population Structure Drives Cultural Diversity In Finite Populations: A Hypothesis For Localized Community Patterns On Rapa Nui (Easter Island, Chile), Carl P. Lipo, Robert J. Dinapoli, Mark E. Madsen, Terry L. Hunt

Anthropology Faculty Scholarship

Understanding how and why cultural diversity changes in human populations remains a central topic of debate in cultural evolutionary studies. Due to the effects of drift, small and isolated populations face evolutionary challenges in the retention of richness and diversity of cultural information. Such variation, however, can have significant fitness consequences, particularly when environmental conditions change unpredictably, such that knowledge about past environments may be key to long-term persistence. Factors that can shape the outcomes of drift within a population include the semantics of the traits as well as spatially structured social networks. Here, we use cultural transmission simulations to …

The Role Of Culture In Sustainable Communities: The Case Of Rapa Nui (Easter Island, Chile), Pamela A. Mischen, Carl P. Lipo

Anthropology Datasets

We explore how the combination of cultural heritage and present-day cultural affili- ations influences the construction of the concept of sustainability at the scale of the community using the case study of Rapa Nui (Easter Island, Chile). We argue that overlapping affiliations—expressed through administrative culture, organizational culture, and professional culture—influence the views held by governance leaders. Furthermore, the role of cultural heritage must be considered in efforts to change and perpetuate sustainability-related behaviors within a community. Using archeo- logical and historical evidence from the pre-contact and historical record of Rapa Nui, we discuss how cultural heritage evolved endogenously in response …

Good Governance Of The Commons Of Rapa Nui: Present And Past, Pamela A. Mischen, Carl P. Lipo, Terry L. Hunt

Anthropology Datasets

Sustainable communities on Rapa Nui (Easter Island, Chile) — whether in the past or present— require good governance of shared and common pool resources. Whether managing communal land needed for cultivation, ground water, stones for tools, fishing grounds, cultural heritage, or tourism, governance structures must balance individual interests with the common needs of the community. Much of the recent history of the island has been dominated by government structures that were imposed by Chilean authorities. Recently, however, much of the island’s cultural heritage has been turned over to local native governance. This shift has challenges due to the complex contemporary …

The Integration Of Lidar And Legacy Datasets Provides Improved Explanations For The Spatial Patterning Of Shell Rings In The American Southeast, Dylan S. Davis, Robert Dinapoli, Matthew Sanger, Carl Lipo

Anthropology Datasets

Archaeologists have struggled to combine remotely sensed datasets with preexisting information for landscape-level analyses. In the American Southeast, for example, analyses of lidar data using automated feature extraction algorithms have led to the identification of over 40 potential new pre-European-contact Native American shell ring deposits in Beaufort County, South Carolina. Such datasets are vital for understanding settlement distributions, yet a comprehensive assessment requires remotely sensed and previously surveyed archaeological data. Here, we use legacy data and airborne lidar-derived information to conduct a series of point pattern analyses using spatial models that we designed to assess the factors that best explain …

The Ethnohistory Of Freshwater Use On Rapa Nui (Easter Island, Chile), Sean W. Hixon, Robert J. Dinapoli, Carl P. Lipo, Terry L. Hunt

Anthropology Faculty Scholarship

Sources of drinking water on islands often present critical constraints to human habitation. On Rapa Nui (Easter Island, Chile), there is remarkably little surface fresh water due to the nature of the island’s volcanic geology. While several lakes exist in volcanic craters, most rainwater quickly passes into the subsurface and emerges at coastal springs. Nevertheless, the island sustained a relatively large human population for hundreds of years, one that built an impressive array of monumental platforms (ahu) and statues (moai). To understand how Rapanui acquired their scarce fresh water, we review ethnohistoric data from first European arrival (1722) through the …

Rapa Nui (Easter Island) Monument (Ahu) Locations Explained By Freshwater Sources, Robert J. Dinapoli, Carl P. Lipo, Tanya Brosnan, Terry L. Hunt, Sean W. Hixon, Alex E. Morrison, Matthew Becker

Anthropology Faculty Scholarship

Explaining the processes underlying the emergence of monument construction is a major theme in contemporary anthropological archaeology, and recent studies have employed spatially-explicit modeling to explain these patterns. Rapa Nui (Easter Island, Chile) is famous for its elaborate ritual architecture, particularly numerous monumental platforms (ahu) and statuary (moai). To date, however, we lack explicit modeling to explain spatial and temporal aspects of monument construction. Here, we use spatially-explicit point-process modeling to explore the potential relations between ahu construction locations and subsis- tence resources, namely, rock mulch agricultural gardens, marine resources, and freshwa- ter sources—the three most critical resources on Rapa …

Automated Mound Detection Using Lidar And Object-Based Image Analysis In Beaufort County, Sc, Carl P. Lipo, Matt Sanger, Dylan Davis

Anthropology Datasets

The study of prehistoric anthropogenic mounded features– earthen mounds, shell heaps, and shell rings – in the American Southeast is stymied by the spotty distribution of systematic surveys across the region. Many extant, yet unidentified, archaeological mound features continue to evade detection due to the heavily forested canopies that occupy large areas of the region, making pedestrian surveys difficult and preventing aerial observation. The use of object-based image analysis (OBIA) as a tool for analysing light detection and ranging (LiDAR) data, however, offers an inexpensive opportunity to address this challenge. Using publicly available LiDAR data from Beaufort County, South Carolina …

Diet Of The Prehistoric Population Of Rapa Nui (Easter Island, Chile) Shows Environmental Adaptation And Resilience, Catrine L. Jarmine, Thomas Larsen, Terry L. Hunt, Carl P. Lipo, Reidar Solsvik, Natalie Wallsgrove, Cassie Ka'apu-Lyons, Hilary G. Close, Brian N. Popp

Anthropology Faculty Scholarship

Objectives: The Rapa Nui “ecocide” narrative questions whether the prehistoric population caused an avoidable ecological disaster through rapid deforestation and over-exploitation of natural resources. The objective of this study was to characterize prehistoric human diets to shed light on human adaptability and land use in an island environment with limited resources.

Materials and methods: Materials for this study included human, faunal, and botanical remains from the archaeological sites Anakena and Ahu Tepeu on Rapa Nui, dating from c. 1400 AD to the historic period, and modern reference material. We used bulk carbon and nitrogen isotope analy- ses and amino acid …

Wagons, Trains, Trucks, And Bottles: Transportation Networks And Commodity Access In Castroville, Texas, Kellam Throgmorton

Anthropology Student Scholarship

The premise of this paper is that changing modes of transportation significantly affected how residents of Castroville, Texas, acquired commodities, which in turn influenced how they expressed particular ethnic, regional, and class identities through consumption. Castroville residents lived (and continue to live) within a broader world system of commodity exchange. As we strive to understand how identities are reflected in and co-created through the objects we surround ourselves with, it is important to remember that economic relations that extend well beyond the local can structure a community’s access to commodities. Geographic space becomes a meaningful variable when we think about …

Using Structure From Motion Mapping To Record And Analyze Details Of The Colossal Hats (Pukao) Of Monumental Statues On Rapa Nui (Easter Island), Sean W. Hixon, Carl P. Lipo, Terry L. Hunt, Christopher Lee

Anthropology Faculty Scholarship

Structure from motion (SfM) mapping is a photogrammetric technique that offers a cost-effective means of creating three-dimensional (3-D) visual representations from overlapping digital photographs. The technique is now used more frequently to document the archaeological record. We demonstrate the utility of SfM by studying red scoria bodies known as pukao from Rapa Nui (Easter Island, Chile). We created 3-D images of 50 pukao that once adorned the massive statues (moai) of Rapa Nui and compare them to 13 additional pukao located in Puna Pau, the island’s red scoria pukao quarry. Through SfM, we demonstrate that the majority of these bodies …

Arqueología Crítica Y Praxis [Critical Archaeology And Praxis], Randall H. Mcguire

Anthropology Faculty Scholarship

La Arqueología se ha utilizado tradicionalmente para apoyar al poder en las arenas de lucha por la economía, las ideologías, las identidades y la política. La arqueología puede ser una forma de praxis para ayudar a crear un mundo más humano, una vez que los arqueólogos se convierten en más que “simples oradores”. La gran mayoría de los arqueólogos practica su arte para obtener el conocimiento del mundo. Varios arqueólogos han tratado de criticar al mundo y el lugar de la arqueología en el mismo. Muy pocos han entrado completamente en la dialéctica de la praxis y han construido una …

The Human Transformation Of Rapa Nui (Easter Island, Pacific Ocean), Terry L. Hunt, Carl P. Lipo

Anthropology Faculty Scholarship

Rapa Nui (Easter Island) has become widely known as a case study of human-induced environmental catastrophe resulting in cultural collapse. The island's alleged "ecocide" is offered as a cautionary tale of our own environmental recklessness. The actual archaeological and historical record for the island reveals that while biodiversity loss unfolded, the ancient Polynesians persisted and succeeded. Demographic "collapse" came with epidemics of Old World diseases introduced by European visitors. In this paper, we outline the process of prehistoric landscape transformation that took place on Rapa Nui. This process includes the role of humans using fire to remove forest and convert …
