Successful Enrichment And Recovery Of Whole Mitochondrial Genomes From Ancient Human Dental Calculus, Andrew T. Ozga, Maria A. Nieves-Colon, Tanvi P. Honap, Krithivasan Sankaranarayanan, Courtney A. Hofman, George R. Milner, Cecil M. Lewis Jr., Anne C. Stone, Christina Warinner

Andrew Ozga

Objectives

Archaeological dental calculus is a rich source of host‐associated biomolecules. Importantly, however, dental calculus is more accurately described as a calcified microbial biofilm than a host tissue. As such, concerns regarding destructive analysis of human remains may not apply as strongly to dental calculus, opening the possibility of obtaining human health and ancestry information from dental calculus in cases where destructive analysis of conventional skeletal remains is not permitted. Here we investigate the preservation of human mitochondrial DNA (mtDNA) in archaeological dental calculus and its potential for full mitochondrial genome (mitogenome) reconstruction in maternal lineage ancestry analysis.

Origins Of An Unmarked Georgia Cemetery Using Ancient Dna Analysis, Andrew T. Ozga, Raul Y. Tito, Brian M. Kemp, Hugh Matternes, Alexandra J. Obregon-Tito, Leslie Neal, Cecil M. Lewis Jr.

Andrew Ozga

Determining the origins of those buried within undocumented cemeteries is of incredible importance to historical archaeologists and, in many cases, the nearby communities. In the case of Avondale Burial Place, a cemetery in Bibb County, Georgia, in use from 1820 to 1950, all written documentation of those interred within it has been lost. Osteological and archaeological evidence alone could not describe, with confidence, the ancestral origins of the 101 individuals buried there. In the present study, we used ancient DNA extraction methods in well-preserved skeletal fragments from 20 individuals buried in Avondale Burial Place to investigate the origins of the …

Comparison Of Two Ancient Dna Extraction Protocols For Skeletal Remains From Tropical Environments, Maria A. Nieves-Colon, Andrew T. Ozga, William J. Pestle, Andrea Cucina, Vera Tiesler, Travis W. Stanton, Anne C. Stone

Andrew Ozga

Objectives

The tropics harbor a large part of the world's biodiversity and have a long history of human habitation. However, paleogenomics research in these climates has been constrained so far by poor ancient DNA yields. Here we compare the performance of two DNA extraction methods on ancient samples of teeth and petrous portions excavated from tropical and semi‐tropical sites in Tanzania, Mexico, and Puerto Rico (N = 12).

Materials and Methods

All samples were extracted twice, built into double‐stranded sequencing libraries, and shotgun sequenced on the Illumina HiSeq 2500. The first extraction protocol, Method D, was previously designed for …

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 …

A Comparison Of Automated Object Extraction Methods For Mound And Shell-Ring Identification In Coastal South Carolina, Dylan S. Davis, Carl P. Lipo, Matthew Sanger

Carl Lipo

One persistent archaeological challenge is the generation of systematic documentation for the extant archaeological record at the scale of landscapes. Often our information for landscapes is the result of haphazard and patchy surveys that stem from opportunistic and historic efforts. Consequently, overall knowledge of some regions is the product of ad hocsurvey area delineation, degree of accessibility, effective ground visibility, and the fraction of areas that have survived destruction from development. These factors subsequently contribute unknown biases to our understanding of chronology, settlements patterns, interaction, and exchange. Aerial remote sensing offers one potential solution for improving our knowledge of …

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 …

Becoming Rabbit: Living With And Knowing Rabbits, Margo Demello

Margo DeMello, PhD

Rabbits, like all animals (human and non-human), have rich internal lives, as people who live intimately with rabbits can attest.1 Living with house rabbits—where rabbits live indoors, without a cage or with minimal caging, as part of the human family—is, to me, the best way to gain some understanding of the rabbit psyche. In addition, living closely with rabbits opens up the possibilities of the humanrabbit relationship—a relationship which, until very recently, was one-sided and based on exploitation. Today, however, with the rise of the house rabbit movement, the subjectivity of rabbits has been exposed, leading to the possibility of …

Pantomime In Great Apes: Evidence And Implications, Ann E. Russon, Kristin Andrews

Kristin Andrews, PhD

We recently demonstrated, by mining observational data, that forest-living orangutans can communicate using gestures that qualify as Pantomime. Pantomimes, like other iconic gestures, physically resemble their referents. More elaborately, pantomimes involve enacting their referents. Holding thumb and finger together at the lips and blowing between them to mean balloon is one example. Here we sketch evidence of pantomime in other great apes, methodological concerns, and sophisticated cognitive capabilities that great ape pantomimes suggest.

The “Babe” Vegetarians: Bioethics, Animal Minds And Moral Methodology, Nathan Nobis

Nathan M. Nobis, PhD

Here I discuss the role the film “Babe” has played in helping people address these challenges and make this moral progress. It is thought that a significant number of young people (mostly girls, now young women) became vegetarians due to their seeing “Babe.” These people are often called “Babe Vegetarians,” influence by what has been called “The Babe Effect.” Many of their stories are found on the internet.

Taurodontism In Review: Methods Of Determination And Anthropological Utility., Scott Legge, Anna Hardin

Scott Legge

Taurodontism, the expansion of the pulp chamber of a tooth, has been a well-known feature of both fossil and modern humans since the early 20th century. In modern populations taurodontism is clinically important, as any increase in pulp chamber size affects the endodontic treatment options, but its archaeological importance among anatomically modern human groups remains unclear. It is often seen as a defining characteristic of the post-canine dentition in Neanderthals and is sometimes used as an indicator of phylogenetic affinity for European fossils. Since the 1960s a number of studies have examined the frequency of taurodontism in modern human populations; …

Cranial Trauma And Interpersonal Violence In Alaskan Natives, Scott Legge

Scott Legge

Cranial trauma is investigated in a skeletal collection from Nunivak Island, Alaska. Trauma was observed in ten individuals from a sample of 121 crania (8.3%). Of the ten, five were males and five were females representing frequencies of 9.8% and 7.1%, respectively. Types of trauma included both blunt force and sharp-edged weapon inflicted injuries. Six of the ten show signs of healing or are completely healed; the other four individuals sustained the trauma at or near the time of death. The occurrence of trauma in the Nunivak Island collection supports previous researchers’ findings of higher frequencies for island dwelling Native …

Early Life Environment, Fertility And Age Of Menarche: A Test Of Life History Predictions Using A Longitudinal Assessment Of Adversity Perception And Economic Status, Dorsa Amir, Matthew R. Jordan, Richard G. Bribiescas

Richard G. Bribiescas

Perceptions of early life environmental adversity can affect the timing of life history transitions and investment in reproductive effort. These effects are well documented in non-human organisms, but have been challenging to test in humans. Here we present evidence of the effects of variables associated with extrinsic mortality and morbidity on reproductive effort in a contemporary American population. Using a longitudinal database that sampled participants (N ≥ 1,579) at four points during adolescence and early adulthood, variables reflective of perceptions of adversity and risk were significantly associated with age of menarche and early adult fertility. While other factors related to …

Lines Of Evidence Used To Reconstruct Patterns Of Diet, Nutrition And Disease In Ancient Populations, Margaret Rebecca Sinclair

Margaret R.Sinclair

Researching, analyzing, and reconstructing the diet, nutrition, and diseases of ancient humans is an interdisciplinary field referred to as bioarchaeology. Bioarchaeologists use several methods to reconstruct the lives of ancient humans. Some of these methods are quantitative, such as skeletal and environmental analysis, while other methods are qualitative such as, interpreting archaeological evidence, using texts as historical reference, and comparing contemporary indigenous populations to ancient hunter-gatherers and pastoralist. Each method provides key insights into the lives of ancient people. I will discuss three of these methods, their techniques, and respective limitations. The three methods are: 1) Analyzing skeletal remains; 2) …

Healing To Reverse The Apocalypse, Julianne E. Henderson Ms.

julianne e. henderson ms.

When I presented the medicinal oil to people and explained what we are studying and aiming to do collectively in our class is to address how we would respond in the event of a crisis or if we were to find ourselves in an apocalyptic landscape. It is a given that maintaining a positive, optimistic outlook is likely to aid us in our long-term survival regardless of what level of adversity we face. This project attempts to combine an important skill, which is knowing how to heal oneself naturally with what Nature provides, with the power of our consciousness to …

Delineating Regions With Permeable Boundaries In New Guinea., Terence Hays

Terence Hays

Hays sets out the linkages among communities and societies as they form networks and regions in New Guinea. Hays reminds us of the long standing concern within the recent literature from New Guinea that supports the "primitive isolates" notion that is still with us. The "my people" syndrome still plagues the legions of researchers who seek to study a small distinct population that is largely uncontaminated by outside influences and remains primitive. He paints the picture of this primitive society by describing New Guinea topographically as a land of inaccessible mountain valleys, impenetrable swamps, and remote rain forests which make …

They Are Beginning To Learn The Use Of Tobacco, Terence Hays

Terence Hays

European colonization attracts laborers whose performance was enhanced by their employers through the use of drugs. Tobacco provided Europeans a way to manipulate populations engaged in new work activities in the non-Western world. Hays argues that control of native labor was the result of control of an addictive American commercial product.

Dental Enamel As A Dietary Indicator In Mammals, Peter Lucas, Paul Constantino, Bernard Wood, Brian Lawn

Paul J. Constantino

The considerable variation in shape, size, structure and properties of the enamel cap covering mammalian teeth is a topic of great evolutionary interest. No existing theories explain how such variations might be fit for the purpose of breaking food particles down. Borrowing from engineering materials science, we use principles of fracture and deformation of solids to provide a quantitative account ofhowmammalian enamelmay be adapted to diet. Particular attention is paid to mammals that feed on ‘hard objects’ such as seeds and dry fruits, the outer casings of which appear to have evolved structures with properties similar to those of enamel. …

Predicting Failure In Mammalian Enamel, Brian Lawn, James Lee, Paul Constantino, Peter Lucas

Paul J. Constantino

Dentition is a vital element of human and animal function, yet there is little fundamental knowledge about how tooth enamel endures under stringent oral conditions. This paper describes a novel approach to the issue. Model glass dome specimens fabricated from glass and back­filled with polymer resin are used as representative of the basic enamel/dentine shell structure. Contact loading is used to deform the dome structures to failure, in simulation of occlusal loading with opposing dentition or food bolus. To investigate the role of enamel microstructure, additional contact tests are conducted on two­phase materials that capture the essence of the mineralized­rod/organic­sheath …

Adaptation To Hard-Object Feeding In Sea Otters And Hominins, Paul Constantino, James Lee, Dylan Morris, Peter Lucas, Adam Hartstone-Rose, Wah-Keat Lee, Nathaniel Dominy, Andrew Cunningham, Mark Wagner, Brian Lawn

Paul J. Constantino

The large, bunodont postcanine teeth in living sea otters (Enhydra lutris) have been likened to those of certain fossil hominins, particularly the ’robust’ australopiths (genus Paranthropus). We examine this evolutionary convergence by conducting fracture experiments on extracted molar teeth of sea otters and modern humans (Homo sapiens) to determine how load-bearing capacity relates to tooth morphology and enamel material properties. In situ optical microscopy and x-ray imaging during simulated occlusal loading reveal the nature of the fracture patterns. Explicit fracture relations are used to analyze the data and to extrapolate the results from humans to earlier hominins. It is shown …

Fracture Susceptibility Of Worn Teeth, Amanda Keown, Mark Bush, James Lee, Chris Ford, Paul Constantino, Brian Lawn

Paul J. Constantino

An experimental simulation study is made to determine the effects of occlusal wear on the capacity of teeth to resist fracture. Tests are carried out on model dome structures, using glass shells to represent enamel and epoxy filler to represent dentin. The top of the domes are ground and polished to produce flat surfaces of prescribed depths relative to shell thickness. The worn surfaces are then loaded axially with a hard sphere, or a hard or soft flat indenter, to represent extremes of food contacts. The loads required to drive longitudinal cracks around the side walls of the enamel to …

Microwear, Mechanics And The Feeding Adaptations Of Australopithecus Africanus, Paul Constantino, Craig Byron, Paul Dechow, Ian Gross, Peter Lucas, Brian Richmond, Callum Ross, Dennis Slice, Mark Spencer, Dennis Strait, Qian Wang, Gerhard Weber, Bernard Wood, Barth Wright

Paul J. Constantino

Recent studies of dental microwear and craniofacial mechanics have yielded contradictory interpretations regarding the feeding ecology and adaptations of Australopithecus africanus. As part of this debate, the methods used in the mechanical studies have been criticized. In particular, it has been claimed that finite element analysis has been poorly applied to this research question. This paper responds to some of these mechanical criticisms, highlights limitations of dental microwear analysis, and identifies avenues of future research.

Properties Of Tooth Enamel In Great Apes, Paul Constantino, Brian Lawn, James Lee, Peter Lucas, Dylan Morris, Tanya Smith

Paul J. Constantino

A comparative study has been made of human and great ape molar tooth enamel. Nanoindentation techniques are used to map profiles of elastic modulus and hardness across sections from the enamel–dentin junction to the outer tooth surface. The measured data profiles overlap between species, suggesting a degree of commonality in material properties. Using established deformation and fracture relations, critical loads to produce function-threatening damage in the enamel of each species are calculated for characteristic tooth sizes and enamel thicknesses. The results suggest that differences in load-bearing capacity of molar teeth in primates are less a function of underlying material properties …
