Poultry are farmed globally, with chicken (Gallus gallus domesticus) being the leading domesticated species. Although domestic bones have been reported from some Early Holocene sites, their origin is controversial and there no reliable bone older than Middle Holocene. Here, we studied goose Tianluoshan—a 7,000-y-old rice cultivation village in lower Yangtze River valley, China—using histological, geochemical, biochemical, morphological approaches. Histological analysis revealed that one of...
Introduction The aim of this study was to determine the geographic origin human remains in Maqaba burial mounds cluster dating from Tylos period (approximately 330 BC AD 300) Bahrain, using stable oxygen isotope analysis dental enamel teeth found mounds. During period, Bahrain an important hub for trade routes between Mediterranean, Mesopotamia, and India. Therefore, immigrants who traveled as merchants cross-regional are possible candidates buried remains. In particular, we hypothesized...
Introduction During the medieval period, cultural attitudes toward leprosy often involved exclusion of infected people from general society. People suffering were moved to live in separate places such as a specific district, village, or hospital. Such actions are social implications how disease and its sufferers viewed dealt with. This study aims investigate whether Kovuklukaya was inhabited by segregated lepers. Methods conducted examining diet individuals using stable isotope analysis bulk...
We have improved a method for isolation and purification of individual amino acids compound-specific radiocarbon analysis (CSRA). To remove high-performance liquid chromatography (HPLC) eluent blanks from isolated acid fractions prior to the (Δ14C) measurement, each fraction was filtered through membrane filter then washed with diethyl ether twice. Radiocarbon measurements on standard processed purified above using elemental analyzer–accelerator mass spectrometry resulted in Δ14C values that...
Abstract Objective The inhabitants of several sites in the Upper Tigris Valley, such as Hakemi Use, domesticated animals and cereals during Pottery Neolithic period, while this valley were hunter–gatherers Pre‐Pottery consuming freshwater terrestrial food resources. However, there is considerable uncertainty surrounding whether or not changes dietary composition accompanied shift production away from foraging. In order to reveal impact development agriculture on human diet over periods...
We determined the stable nitrogen isotopic composition (δ15N) of amino acids in bone collagen from samples three archaeological herbivores (cattle, sheep, and goats), collected Tell Ain el-Kerkh Neolithic site Syria. Bulk δ15N values exhibited significant differences between species (by up to 3.2‰), were strongly correlated with those glycine (R2 = 0.87), most abundant acid collagen. On other hand, two minor (glutamic phenylalanine) different within narrow ranges (0.9‰ 0.5‰, respectively),...
Several cases that do not fit the agricultural adaptation model, in which people's health deteriorated with shift from hunting-gathering to farming, have been reported, such as introduction of rice agriculture during Yayoi Period Japan and Iron Age Southeast Asia, where was maintained or improved. However, farmers homeland areas has rarely reported. This study aims clarify frequency degree stress markers inscribed on Neolithic human bones Yangtze River Delta, one origins agriculture,...
The origins of agriculture in East Asia can be distinguished between rice southern China and millet (foxtail broomcorn millet) the north. In Longshan period (c. 4300–3800 cal BP), with northward expansion farming, a mixed rice–millet agricultural area was established Central Plains China, which also core establishment early state. interaction these two traditions is significant as backdrop for emergence Erlitou civilization, although specifics this cultural contact remain unclear. study, we...
At Aşıklı Höyük, one of the earliest Pre-pottery Neolithic mound sites in Central Anatolia, a shift animal utilization from broad-spectrum exploitation diverse species to concentration on managed caprines has been observed. Changes balance meat plant foods over same time frame remain an open question. In this study, carbon and nitrogen isotopic analyses bulk collagen compound-specific analysis amino acids were undertaken for human remains elucidate dietary impact hunting herding transition...
The chemical analysis of animal bones from ancient sites has become a common approach in archeological research investigating utilization and domestication by past humans. Although several indicators have been used to determine pig management practices societies, one indicator that can clarify human-animal relationships the early stages is change animal’s diet its wild diet, which be detected using isotope bones. Omnivores, such as boars, are assumed shared foods with humans their...
Abstract This study analyzes the nitrogen isotope composition of individual amino acids in collagen extracted from human bone samples Gaoshan, Yingpanshan, and Xinyicun sites Sichuan, where baseline is unavailable or incomparable with isotopic data derived remains. It aims to understand food compositions inhabitants at these sites, spanning period late Neolithic middle Bronze Age, during which time agriculture domestication animals were introduced region became increasingly important. The δ...
