“…Lipid residue analysis, however, can identify broad food types that were processed in pre-contact vessels, allowing for reconstructions of diet and resource utilization that few other types of analyses can provide. Lipid residue analysis was conducted by Mary Malainey (Malainey et al 1999a(Malainey et al , 1999bMalainey 2007) and Timothy Figol of Brandon University (Malainey and Figol 2015: Appendix 1). This process is destructive as it requires sherds to be crushed to allow for the extraction of lipids from the ceramic fabric, so only five sherds from each assemblage were submitted for analysis.…”

“…Acorns, although not as high in fat content as other nuts, contain relatively high levels of C18:1 isomers (Malainey et al 1999a); however, all Sand Point samples had C18:1 levels of less than 5 percent (Malainey and Figol 2015). While thermal degradation of fatty acids during cooking processes is common, lipids extracted from pottery on Grand Island, Michigan, where early pottery has been associated with nut oil processing, contained C18:1 levels between 55 percent and 80 percent (Malainey et al 1999b;Skibo et al 2009); thus, Sand Point vessels do not meet expectations for signatures indicating intensive nut processing.Animals represented by the Sand Point faunal assemblage include a variety of small mammals, white-tailed deer, trout, and whitefish, as well as some waterfowl and black bear, which are mostly reflected in the lipid residues (Martin and Rhead 1980). Despite Sand Point's interpreted function as a fall fishery, few fish remains were preserved at the site, presumably as a result of soil acidity.…”

Woodland Pottery Function, Cooking, and Diet in the Upper Great Lakes of North America

A multidimensional approach to functional analysis was employed to examine pottery use, cooking, and subsistence in pre-European North American contexts. A variety of analytic techniques were applied to ceramic assemblages from two sites on the south shore of Lake Superior: the Middle Woodland Naomikong Point site and the Late Woodland Sand Point site. The analyses of both technical attributes and use-alteration traces suggest that a majority of pottery vessels from these sites were used for cooking throughout the Woodland period. Lipid residue analysis corroborates traditional subsistence information but specifies which foods were cooked in pottery vessels. Vessel size varies according to context rather than by time or by function, with larger vessels associated with ritual areas and smaller vessels originating from domestic spheres, a trend potentially related to feasting behavior. Interior carbonization patterns change in frequency between the Middle and Late Woodland periods, suggesting a shift in cooking and possibly subsistence practices.keywords ceramics, pottery function, cooking practices, great lakes A recent trend in ceramic analysis has been the increased use of proxy observations to understand archaeological vessel functions (Braun 1983;Blitz 1993;Kobayashi 1994;Skibo and Blinman 1999;Arthur 2002Arthur , 2003Skibo et al. 2009). This approach stands in contrast to the more traditional analyses that have largely focused on the social and spatiotemporal implications of stylistic attributes (i.e., Wheat et al. 1958;McPherron 1967;Janzen 1968;Sabloff and Smith 1969;Brose 1970;Dorothy 1978Dorothy , 1980. Functional analyses can be used to infer culinary practices and the role of pottery in everyday life, both in relation to subsistence and nonculinary functions, as well as its use in special contexts, thereby expanding the midcontinental journal of archaeology, Vol. 41 No. 3, Fall, 2016, 207- breadth of information that can be gleaned from ceramic assemblages. Building on this premise, a multidimensional analytic approach was developed and used to investigate the diet and cooking practices of inhabitants of and the function of pottery vessels from two Woodland sites on Michigan's Upper Peninsula. Physical characteristics, the presence and locations of use-alteration traces, depositional contexts, lipid residue analysis, and ethnographic sources were all examined or employed to reconstruct ancient pottery use in the Upper Great Lakes region (Kooiman 2012).This study explores the functions of Upper Great Lakes pottery through assemblages from two coastal sites on the south shore of Lake Superior: the Naomikong Point (20CH2) site and the Sand Point (20BG14) site. Both are multicomponent sites, but analysis focused on pottery from the Laurel Middle Woodland component of Naomikong Point (Janzen 1968) and the Late Woodland component of Sand Point (Dorothy 1978(Dorothy , 1980). Skibo's (2013) model of pottery function analysis entails the evaluation of both technical properties and use-alteration traces to infer...

“…En este sentido, los ácidos insaturados (aquellos que poseen enlaces dobles entre átomos de carbón) se degradan más rápidamente que los saturados (aquellos que no poseen enlaces dobles entre átomos de carbón), al igual que los componentes de cadenas largas en comparación a los de cadenas cortas. Esta situación complejiza las comparaciones directas entre los perfiles de ácidos grasos obtenidos de los materiales arqueológicos y aquellos procedentes de recursos actuales no sometidos a cocción (Buonasera, 2005;Eerkens, 2005Eerkens, , 2007Malainey et al 1999a).…”

Análisis preliminar de ácidos grasos recuperados de cerámicas arqueológicas del curso del Río Colorado (Norpatagonia Oriental): Aportes para la subsistencia de grupos cazadores-recolectores

RESUMENEn este trabajo se presentan los resultados preliminares de los análisis de ácidos grasos realizados en tiestos cerámicos recuperados de tres sitios arqueológicos del curso inferior del río Colorado (Norpatagonia oriental, Argentina). Los contextos arqueológicos corresponden al Holoceno tardío, tanto inicial (ca. 3.000-1.000 años AP) como final (ca. 1.000-250 años AP). La información obtenida sugiere la cocción de grandes herbívoros y posiblemente de plantas y/o médula ósea, así como la presencia de recursos de origen marino, muy probablemente peces. En términos generales, estos resultados son consistentes con las principales tendencias descriptas en el modelo de subsistencia propuesto para el área, generado desde los estudios zooarqueológicos y de los análisis de isótopos estables en restos óseos humanos. Además, los resultados obtenidos de los análisis de ácidos grasos permitieron inferir aspectos relacionados con los lugares específicos de explotación y consumo de ciertos recursos (i.e., peces) y estrategias de movilidad y cobertura del paisaje por parte de los grupos cazadores-recolectores del Holoceno tardío.PALABRAS CLAVE: ácidos grasos, Norpatagonia, subsistencia, Holoceno tardío PRELIMINARY ANALYSIS OF FATTY ACIDS RECOVERED FROM ARCHAEOLOGICAL POTTERY OF THE LOWER COURSE OF THE COLORADO RIVER (NORTH-EASTERN PATAGONIA): CONTRIBUTIONS TO THE HUNTER-GATHERERS SUBSISTENCE PATTERNSABSTRACT This paper presents the preliminary results obtained of the analysis of fatty acids recovered from pottery sherds from three archaeological sites of the lower course of the Colorado River (North-eastern Patagonia, Argentina).

Influence of Wet–Dry Cycling on the Self‐Assembly and Physicochemical Properties of Model Protocellular Membrane Systems

2021

Wet‐dry cycles are hypothesized to facilitate fundamental steps towards the emergence of life on prebiotic Earth. Multiple wet–dry cycles have been demonstrated to promote biopolymer formation. However, the effect of recurring wet‐dry cycles on the self‐assembly and physicochemical properties of model protocellular membranes remains somewhat obscure. Towards this end, we evaluated the structural and chemical stability of composite model protocell membrane systems composed of single chain amphiphiles, under wet‐dry cycles. The change in membrane properties, size and encapsulation was also investigated. Model protocellular membrane systems were found to reassemble into vesicles even over multiple cycling. Wet‐dry cycling induced compositional changes in the membranes, leading to changes in their physicochemical properties. Multiple cycles were also found to increase vesicular encapsulation of calcein. This work outlines how wet‐dry cycling on the early Earth could have helped in the formation of protocellular entities and their evolution on prebiotic Earth.
