Dental calculus (calcified dental plaque) is prevalent in archaeological skeletal collections and is a rich source of oral microbiome and host-derived ancient biomolecules. Recently, it has been proposed that dental calculus may provide a more robust environment for DNA preservation than other skeletal remains, but this has not been systematically tested. In this study, shotgun-sequenced data from paired dental calculus and dentin samples from 48 globally distributed individuals are compared using a metagenomic approach. Overall, we find DNA from dental calculus is consistently more abundant and less contaminated than DNA from dentin. The majority of DNA in dental calculus is …

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

Carl Lipo

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 …

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

Carl Lipo

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 …

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

Carl Lipo

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 …

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

Carl Lipo

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 …

Resource Scarcity And Monumental Architecture: Cost Signaling On Rapa Nui (Easter Island), Chile, Dylan Davis, Carl P. Lipo

Carl Lipo

Costly signaling theory (CST) explains a variety of elaborate behavioral displays as a consequence of competition over resources when the risk of direct conflict is high. Within an archaeological context, monumental architecture is potentially explained as a facet of costly signaling between individuals and groups. On Rapa Nui, CST offers an explanation for the construction of labor-intensive monuments including massive statues (moai) and ceremonial platforms (ahu). Using hypotheses derived from CST and spatial data about the distribution of archaeological features, the degree to which CST accounts for the investment in prehistoric monumental architecture on Rapu Nui is evaluated.

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

Carl Lipo

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 …

The Endurance Of Tell Qarqur: Settlement Resilience In Northwestern Syria During The Late Bronze And Iron Ages (Ca. 1200 – 700 Bc), Eric Robert Jensen

Eric Roberts, MD

This dissertation analyzes the material culture, paleobotanical, and faunal remains excavated at the site of Tell Qarqur, Syria, recovered from occupational levels dating from the end of the Late Bronze Age to the Iron II period (from approximately 1200 to 700 BC). Based on archaeological evidence and ancient textual sources, many ancient Near Eastern kingdoms and polities endured social and political turmoil during the late 13th and early 12th centuries BC. Most likely caused by an unknown hostile group or groups, the destruction of monumental scale architecture and the disruption to the people of Qarqur’s agricultural and animal husbandry practices …
