Prehistoric human biological adaptation

p. 157-270 : ill., maps ; 26 cm.Includes bibliographical references (p. 255-270)."Skeletal remains from the prehistoric coast of Georgia are the basis for this study. The effects of agriculture on the human skeleton are examined and explained in the present paper. The region was chosen because (1) there is a large skeletal series representative of both an early preagricultural adapatation (2200 B.C.-A.D. 1150) and a later mixed agricultural and hunting-gathering adaptation (A.D. 1150-A.D. 1550); (2) the Georgia coast represents continuous in situ cultural development from at least 2200 B.C. to A.D. 1550, implying human biological continuity for at least 3500 years prior to European contact; and (3) the economic regime for the Georgia coast has been documented by a large body of archaeological and ethnohistoric data. A series of skeletal and dental changes are viewed in light of an adaptational model encompassing disease and size of the hard tissues - skeletal and dental - and their respective responses to the behavioral shift from a hunting and gathering lifeway to one that incorporated corn agriculture after A.D. 1150. The model consists of two parts. First, with the introduction of an agriculture-based diet and consequent increase in population size and density, the pathology reflecting a general rise in occurrence of infectious disease due to an expansion in population size and a high dietary carbohydrate base should increase. Second, with the adoption of corn as a major dietary constituent, the softer foodstuffs and more sedentary lifeway associated with that adaptation should result in a respective decrease in functional demand on the masticatory complex in particular and on the body in general. In addition, the element of poor nutrition should come into play in an economy in which plant domesticates, and corn in particular, are the focus of diet. The comparison and analysis of the pathology and metric data support the model. In addition, the detailed examination of these data by sex suggests that the behavioral alterations that occurred consequent to the change in lifeway differentially affected females"--P. 159

Regional Variation in the Pattern of Maize Adoption and Use in Florida and Georgia

Dietary reconstruction using carbon and nitrogen stable isotopes from archaeological human bone samples from coastal Georgia and northern and Gulf Coast Florida dating between 400 B.C. and A.D. 1700 serves to illustrate the complexity of the agricultural transition in that region. Isotope analysis of 185 collagen samples drawn from early prehistoric, late prehistoric, and contact-period mortuary sites encompasses two major adaptive shifts in the region, namely the adoption of maize agriculture in late prehistory and the increased emphasis on maize during the mission period. Prior to European contact—and especially before the establishment of Spanish missions among the Guale, Yamasee, Timucua, and Apalachee tribal groups—diet was strongly influenced by local environmental factors. Before contact, coastal and inland populations had different patterns of food consumption, as did populations living in Georgia and Florida. Coastal populations consumed more marine and less terrestrial foods than inland populations. In general, maize was adopted during the eleventh century A.D. by virtually all Georgia populations. However, with the exception of the Lake Jackson site, a major Mississippian center in northern Florida, Florida populations show little use of maize before contact. Following European contact, maize became wide-spread, regardless of location or habitat within the broad region of Spanish Florida. Missionization appears to have been an important factor in the convergence of native diets toward agriculture and away from foraging. This increased emphasis on maize contributed to a decline in quality of life for native populations

Refuge-Deptford mortuary complex

Seasonal growth variations in the shells of recent and prehistoric specimens of Mercenaria mercenaria from St. Catherines Island, Georgia / George R. Clark II."Data and implications from nine burial mounds excavated by crews of the American Museum of Natural History on St. Catherines Island, Georgia, are given in this monograph. As a group, these nine sites define a surprisingly homogeneous pattern and these data comprise virtually all that is known regarding the mortuary customs practiced along the Georgia and Florida coast between ca. 1500 B.C. to A.D. 600. The sites are rather unspectacular sand mounds, which exhibit a remarkably consistent stratigraphic patterning. The skeletal materials recovered are poorly preserved, except in the rare case when shell was added to the interment. The radiocarbon evidence, consisting of 29 determinations from the nine mounds, strongly suggests a marked periodicity in the use of these sites. In all cases, the areas seem to have been visited for centuries - in some cases millenia - prior to the actual construction of the mortuary mound. Several graves were placed into this pre-mound surface, and mound-building activities occurred at all sites sometime during the first 600 years A.D. A number of intrusive burials were added shortly thereafter, and then ceremonial activities virtually ceased at all sites. Most cultural materials found inside the mounds were accidental inclusions which resulted from pre-mound sacred (and probably secular) activities. Very few deliberate grave offerings were found. The biocultural evidence suggests that the Refuge-Deptford population enjoyed good health, although they suffered from an extreme rate of dental attrition. Although the data are limited, these sites seem to reflect an egalitarian sociopolitical organization operative during Refuge-Deptford times. The relatively high proportion of bundle burials seems to suggest that the annual round of these peoples exploited both island and mainland resources. We offer a number of cautious speculations regarding the nature of ritual and symbolism during the Refuge and Deptford phases. These suggestions are a variety of hypotheses that require testing with data from both mortuary and habitation sites of this period"--P. 5

St. Catherines period mortuary complex

p. 272-341 : ill., 1 map ; 26 cm.Includes bibliographical references (p. 340-341)."The results of archaeological excavations of two St. Catherines period burial mounds - Marys Mound and Johns Mound - by field crews from the University of Georgia and the American Museum of Natural History are presented. Analysis of the ceramics recovered from the two mortuary localities suggests that both mounds were constructed during the terminal phase of the St. Catherines period, probably during the late twelfth or early thirteenth century A.D. Study of the human skeletal remains suggests that these people were physically robust and enjoyed good health, both skeletal and dental. Analysis of nonhuman skeletal remains shows that most identified taxa are present on St. Catherines Island today. In addition, the presence of the domestic pig, Sus scrofa, in association with one iterment from Johns Mound, points to historic (Altahama) period use of this locality. Thin-section analysis of whole clams (Mercenaria mercenaria) from both sites indicates that time of harvesting or death for all specimens falls within 'late fall' to 'late spring' (November to May)"--P. 273

Exceptionally rapid oxime and hydrazone formation promoted by catalytic amine buffers with low toxicity

Hydrazone and oxime bond formation between α-nucleophiles (e.g. hydrazines, alkoxy-amines) and carbonyl compounds (aldehydes and ketones) is convenient and is widely applied in multiple fields of research. While the reactants are simple, a substantial drawback is the relatively slow reaction at neutral pH. Here we describe a novel molecular strategy for accelerating these reactions, using bifunctional buffer compounds that not only control pH but also catalyze the reaction. The buffers can be employed at pH 5-9 (5-50 mM) and accelerate reactions by several orders of magnitude, yielding second-order rate constants of >10 M-1s-1. Effective bifunctional amines include 2-(aminomethyl)imidazoles and N,N-dimethylethylenediamine. Unlike previous diaminobenzene catalysts, the new buffer amines are found to have low toxicity to human cells, and can be used to promote reactions in cellular applications

Jones -- The history of St. Catherines Island after 1684 / Roger S. Durham and David Hurst Thomas -- Appendix: Notes on ethnohistorical resources and methodology / Grant D. Jones."This volume, the first in a series, considers the natural and cultural background to anthropological research being conducted on St. Catherines Island, Georgia. The island is one of a complex series of barrier islands, of various orgins. The extant vegetation is an interesting mixture of natural succession, periodically disrupted by recent historical processes. Archaeologists have worked on St. Catherines Island discontinuously since 1896, when C.B. Moore conducted excavations in several prehistoric burial mounds. The University of Georgia then conducted a program of burial mound and midden excavations in 1969-1970, and the American Museum of Natural History began intensive archaeological investigations on St. Catherines Island in 1974. The ethnohistory of the Guale Indians is discussed in detail, suggesting that they were essentially a riverine people with strong internal trade contacts. Guale political organization was that of the classic Creek chiefdom. Each chiefdom maintained two principal towns, and may have been organized according to dual political organization. This interpretation contrasts sharply with the traditional view of the Guale, who are often characterized as isolated, scattered, shifting cultivators. The volume concludes with a historical outline of St. Catherines Island from the early Spanish mission period up to present times"--P. 159

South End Mound complex

46 p. : ill., maps ; 26 cm.Includes bibliographical references (p. 44-46)."This volume presents results of archaeological excavations of two prehistoric burial mounds on St. Catherines Island, Georgia. South End Mound I is an Irene period mortuary site, initially excavated by C.B. Moore during the winter of 1896-1897. Although Moore adequately described his investigations in a subsequent publication, he retained only six complete ceramic vessels for later analysis. These vessels have been reexamined and are discussed here. None of the skeletal materials excavated by Moore, to our knowledge, was saved for later analysis. Field crews from the American Museum of Natural History recently reexcavated parts of this site, finding evidence that at least some of the primary human burials previously exposed by Moore remain intact beneath the backdirt of South End Mound I. Further investigation might be fruitful. South End Mound II, a previously unexplored mortuary site, was discovered not far from Moore's excavations. This St. Catherines/Savannah period burial mound, extensively excavated by the American Museum of Natural History, had a central pit containing two cremations and a mass grave containing at least 15 individuals. Grave goods included a perforated copper sheet, worked galena, a river otter mandible, and a polished stone pendant. Prehistoric copper has rarely been reported from archaeological contexts from this area and, to our knowledge, this is the first occurrence of galena in coastal Georgia. Mound construction methods resemble those employed at Johns and Marys mounds, two roughly contemporary mortuary sites on St. Catherines Island"--P. 4

Mobility and kinship in the world’s first village societies

Around 10,000 y ago in southwest Asia, the cessation of a mobile lifestyle and the emergence of the first village communities during the Neolithic marked a fundamental change in human history. The first communities were small (tens to hundreds of individuals) but remained semisedentary. So-called megasites appeared soon after, occupied by thousands of more sedentary inhabitants. Accompanying this shift, the material culture and ancient ecological data indicate profound changes in economic and social behavior. A shift from residential to logistical mobility and increasing population size are clear and can be explained by either changes in fertility and/or aggregation of local groups. However, as sedentism increased, small early communities likely risked inbreeding without maintaining or establishing exogamous relationships typical of hunter-gatherers. Megasites, where large populations would have made endogamy sustainable, could have avoided this risk. To examine the role of kinship practices in the rise of megasites, we measured strontium and oxygen isotopes in tooth enamel from 99 individuals buried at Pınarbaşı, Boncuklu, and Çatalhöyük (Turkey) over 7,000 y. These sites are geographically proximate and, critically, span both early sedentary behaviors (Pınarbaşı and Boncuklu) and the rise of a local megasite (Çatalhöyük). Our data are consistent with the presence of only local individuals at Pınarbaşı and Boncuklu, whereas at Çatalhöyük, several nonlocals are present. The Çatalhöyük data stand in contrast to other megasites where bioarchaeological evidence has pointed to strict endogamy. These different kinship behaviors suggest that megasites may have arisen by employing unique, community-specific kinship practices

Bioarchaeology of Neolithic Çatalhöyük Reveals Fundamental Transitions in Health, Mobility, and Lifestyle in Early Farmers

The transition from a human diet based exclusively on wild plants and animals to one involving dependence on domesticated plants and animals beginning 10,000 to 11,000 y ago in Southwest Asia set into motion a series of profound health, lifestyle, social, and economic changes affecting human populations throughout most of the world. However, the social, cultural, behavioral, and other factors surrounding health and lifestyle associated with the foraging-to-farming transition are vague, owing to an incomplete or poorly understood contextual archaeological record of living conditions. Bioarchaeological investigation of the extraordinary record of human remains and their context from Neolithic Çatalhöyük (7100–5950 cal BCE), a massive archaeological site in south-central Anatolia (Turkey), provides important perspectives on population dynamics, health outcomes, behavioral adaptations, interpersonal conflict, and a record of community resilience over the life of this single early farming settlement having the attributes of a protocity. Study of Çatalhöyük human biology reveals increasing costs to members of the settlement, including elevated exposure to disease and labor demands in response to community dependence on and production of domesticated plant carbohydrates, growing population size and density fueled by elevated fertility, and increasing stresses due to heightened workload and greater mobility required for caprine herding and other resource acquisition activities over the nearly 12 centuries of settlement occupation. These changes in life conditions foreshadow developments that would take place worldwide over the millennia following the abandonment of Neolithic Çatalhöyük, including health challenges, adaptive patterns, physical activity, and emerging social behaviors involving interpersonal violence
