Plant microfossil analysis was carried out on anthropogenic deposits from Yuku rock shelter, possibly occupied from before 14,200 cal. BP to recent times, in the Papua New Guinea Highlands. Elaeocarpus pollen has extremely high percentages throughout. Starch residues of lesser yam (Dioscorea esculenta) and one or more, undifferentiated Dioscorea species were identified, suggesting processing of these taxa since first use of the site. The latter include Dioscorea alata, Dioscorea bulbifera, Dioscorea nummularia and Dioscorea pentaphylla. Pollen and phytoliths of banana (Musa) appear 5200 cal. BP. We cannot differentiate between naturally growing and cultivated yams and bananas. Putative truffle (hypogeous Ascomycotina) spores in the deposits suggest foraging of truffles.  相似文献

The relationship between environmental variation and subsistence practices is a central point of discussion in much Oceanic archaeology. While human predation can significantly reduce prey populations, environmental variation also contributes to reductions in prey abundance, possibly leading to increased human competition and resource scarcity. At the Natia Beach site, Nacula Island, Fiji, geoarchaeological evidence suggests that coastal progradation began soon after initial occupation of the coastal plain. Additionally, at approximately 650 BP a marked increase in clay and silt deposition occurred. Changes in coastal geomorphology may be explained by landscape response to regional Mid-Holocene sea level fall combined with human induced soil erosion due to upland settlement. Smaller scale environmental changes associated with climate variability may have also played a role. Additionally, landscape change appears to have had a measurable impact on local nearshore mollusks that are sensitive to high levels of water turbidity. Minor evidence of human exploitation is observable in this shellfish assemblage, although changes in predation pressure may have allowed shellfish populations to recover. Increased ceramic diversity and fortified settlements also appear at approximately 650 BP on Nacula and other parts of Fiji. The suite of changes at Natia may be explained by processes of regional and local environmental changes, and human adaptation in terms of subsistence, spatial organization, and competition.  相似文献

We present the results of a detailed taphonomic and zooarchaeological study of the faunal remains from the Upper Palaeolithic layers of Dzudzuana Cave, Republic of Georgia. This study presents the first carefully analysed Upper Palaeolithic faunal assemblage from the southern Caucasus and thus serves as a significant point of reference for inter‐regional studies of Upper Palaeolithic subsistence in Eurasia. A series of intra‐site taphonomic comparisons are employed to reconstruct the depositional history of the bone assemblages within the different occupational phases at the site and to investigate subsistence, meat procurement and bone‐processing strategies. Caucasian tur (Capra caucasica), aurochs (Bos primigenius) and steppe bison (Bison priscus) were the major prey species throughout the Upper Palaeolithic. Their frequencies do not change significantly over time, and nor does bone preservation vary by layer. The assemblage is characterised by significant density‐mediated biases, caused by both human bone‐processing behaviours and in situ post‐burial bone attrition. Bone marrow extraction produced large numbers of unidentified bone fragments, many exhibiting green bone fractures. The density and size of bone assemblages and the extent of fragmentation indicate that Dzudzuana Cave was repeatedly occupied by Upper Palaeolithic foragers over many years. Skeletal part representation and butchery marks from all stages of carcass processing suggest that prey occasionally underwent field butchery. Intra‐site taphonomic comparisons highlight uniform patterns of cultural and economic behaviours related to food procurement and processing strategies.

From where did the early inhabitants of the Badagry coastal area of southwestern Nigeria originate? Has the area been occupied from “ancient times,” as claimed by oral traditions? What was the nature of the environment and subsistence of these early inhabitants? Excavations at Apa, west of Badagry, provided answers to these questions. A radiocarbon date of 2670 ± 90 bp showed that human occupation there is at least 3000 years old, and implied occupation during the Late Stone Age. The occupation was in two phases: a prehistoric phase, during which Apa site 1 (Ap1) was occupied, and an historic phase, with occupation of Apa site 2 (Ap2). Sedimentological and archaeological data also showed that the environment at the beginning of occupation was similar to today. The presence of a groundstone axe, charred palm kernels, and charcoal at the Ap1 site is interpreted to imply the clearing and burning of vegetation, probably preparatory to planting and the exploitation of oil palm (Elaeis guineensis) from about 2670 ± 90 bp. D'où sont venus les premiers habitants de la région côtiere Badagry du sud-ouest du Nigeria? Est-il vrai que la région a été occupé depuis les temps anciennes, comme confirme les traditions orales? Quelle étaient la nature de l'environnement et du subsistence de ces habitants préhistoriques? Des fouilles archéologiques à Apa, a l'ouest de Badagry, ont fourni des réponses nécessaires à ces questions. Un date radiocarbone de 2670 ± 90 bp a montré que les activités humaines de ce site date au moins de 3000 années, qui indique que l'occupation des habitants à c'endroit étais durant la periode de l'Age de la Pierre Recent. L'occupation de cette region était en deux phases: un phase prehistorique, la période pendant lequelle le site d'Apa 1 (Ap1) était occupé, et la phase historique, qui a marqué l'occupation du deuxième site d'Apa 2 (Ap2). Les données de la sedimentologie et de l'archéologie ont aussi montrent que l'environnement au commencement d'occupation était similaire de nos jours. On pense que la presence d'un hache “groundstone,” de l'amande de palmier et du charbon à la site d'Ap1 indiques la déstruction de la vegetation, preparant probablement la terre pour la semence et l'exploitation du l'huile de palme (Elaeis guineensis) d'environ de 2670 ± 90 bp.  相似文献

Southeast Asia's transition to rice agriculture is often used as an exception to the general pattern of health decline at the agricultural transition. Niah Cave is the largest known Southeast Asian Neolithic cemetery, providing valuable information about subadult health during the agricultural transition in this region. This study examines the health status and mortuary treatment of subadult skeletal remains (Minimum Number of Individuals (MNI) = 49) from the Neolithic cemetery of Niah Cave, Sarawak, Malaysia (1500–200 bc ). This study found that few cases of cribra orbitalia (4.6%) and porotic hyperostosis (14%). However, nonspecific infections may have been a risk factor for subadults as over half (65%) died with active cases of periosteal reactions on their long bones. Differential diagnosis determined that possible factors for this include parasite load, rickets and scurvy. Mortuary practices indicate that subadults may have been treated differently in phases 1 and 2 but were grated similar mortuary treatment in phases 3 and 4. This study suggests that changes in mobility patterns may have placed subadults at risk for increased parasite load and vitamin deficiency, while the role of subadults within the community may have changed over time.

Two European geographers present the findings of a sizeable survey (n = 7,515) providing a detailed geographical analysis of household incomes and reliance on personal subsidiary garden plots across Kazakhstan. The authors focus on assessing the extent to which Kazakhstan's rising GDP during the post-Soviet period has coincided with an increase in the general population's personal income and ability to secure adequate food supplies for personal consumption. The fine geographical scale of analysis of the survey data (significantly less coarse than oblast-level data) enabled them to identify regions characterized by "trickle-down" income, largely centered on the country's two main urban centers and areas of resource exploitation. The patterns revealed in the paper have relevance to the debate concerning the uneven distribution of benefits from resource exploitation (notably oil and gas) to Kazakhstan's population.

Over the last several decades new sets of information have provided a more detailed understanding of the rise and character of the Indus Civilization as well as its decline and decentralization. This article begins with a summary of the major historical developments in the archaeology of the Indus Valley Tradition and a definition of terms found in the literature. A general discussion of the environmental setting and certain preconditions for the rise of urban and state-level society is followed by a summary of the major aspects of the Harappan Phase of the Indus Valley Tradition. This summary includes discussions of settlement patterns, subsistence, architecture, trade and exchange, specialized crafts, language, religion, and social organization. The Localization Era or decentralization of the urban centers is also addressed.  相似文献

Marine fish bones are abundant components of human food remains at prehistoric sites in the eastern Tropical Pacific. Their quantification and interpretation in terms of human procurement strategies have been hampered by the use of large-meshed sieves and by the obstacles presented to faunal experts by fish taxonomic diversity. Since many important food fish families are speciose, this paper emphasizes the importance of species-level identifications. Making extensive use of Spanish-language articles on fish distribution and ecology, and the commercial and artisanal fisheries literature, it identifies groups of nearshore and littoral fish species that show greater and lesser tolerance for hard substrates (reefs and rocks), estuaries and coastal lagoons, and deeper clearer waters farther offshore. Most of the regional archaeological sites were located near estuarine habitats. The drab-colored fish they attract are generally poorly known. Hence, a particularly detailed analysis is offered of fish behavior within low salinity coastal inlets. Fourteen archaeofaunal fish samples from Costa Rica, Panama, and Ecuador are evaluated in the light of the environmental information generated by the biological and fisheries surveys. It is concluded that most sites have a broadly estuarine orientation and that the input of hard substrates is everywhere <10%. Two sites, Salango, in Ecuador, and Vidor, in Costa Rica, exploited epipelagic fish that swim in large shoals and deep water demersal predators. Sites situated more than 10 km from the coast exploited a wide variety of marine fish. In Parita Bay, Panama, a comparison of fish faunas from Cerro Mangote (6000 B.P.) and Sitio Sierra (1800 B.P.) elicits the hypothesis that regional fishing strategies shifted between these dates from a shore-based, netless strategy to a more complex one that incorporated fine-meshed gill-nets and watercraft.  相似文献
