Farming domesticated millets, tending pigs, and hunting constituted the core of human subsistence strategies during Neolithic Yangshao (5000–2900 BC). Introduction of wheat and barley as well as the addition of domesticated herbivores during the Late Neolithic (∼2600–1900 BC) led to restructuring of ancient Chinese subsistence strategies. This study documents a dietary shift from indigenous millets to the newly introduced cereals in northcentral China during the Bronze Age Eastern Zhou Dynasty (771–221 BC) based on stable isotope analysis of human and animal bone samples. Our results show that this change affected females to a greater degree than males. We find that consumption of the newly introduced cereals was associated with less consumption of animal products and a higher rate of skeletal stress markers among females. We hypothesized that the observed separation of dietary signatures between males and females marks the rise of male-biased inequality in early China. We test this hypothesis by comparing Eastern Zhou human skeletal data with those from Neolithic Yangshao archaeological contexts. We find no evidence of male–female inequality in early farming communities. The presence of male-biased inequality in Eastern Zhou society is supported by increased body height difference between the sexes as well as the greater wealth of male burials.
Textual records and archaeological evidence reflect prosperous animal farming in the Eastern Zhou of ancient China (770–220 BC), but knowledge of how these animals were fed is limited. Here, we present the first stable isotopic study investigating animal husbandry strategies of this period. Isotopic features of faunal remains of 5 species discovered in Songzhuang cemetery suggest that pigs and dogs were fed on mixed diets with substantial internal variation, and cattle were fed mainly on a C4‐based diet. This is similar to the situation found in another Eastern Zhou cemetery, Tianli. Evidence from the 2 sites demonstrates that domesticated omnivores were raised in quite flexible ways, but cattle raising practices show consistency in different areas of China's Central Plains. Inter‐burial analysis of isotopic data suggests a very small scale of cattle farming during this period. Temporal comparison reveals that early Bronze Age people on the Plains had already established practices of provisioning cattle with C4 plants, and that these practices were inherited by Eastern Zhou people without significant change. However, manuring practices of the historical period likely elevated stable nitrogen isotope values of cattle slightly relative to Bronze Age values. This study sheds light on animal management practices on the plains during early historical times, and also provides faunal isotopic values for reference in studies of contemporary human diets.
