Diversification in Feeding Pattern of Livestock in Early Bronze Age Northwestern China

Animal husbandry has been an indispensable part of human subsistence since the origin agriculture. Along with prehistoric cultural exchange, several kinds major domestic animals diffused and gradually got popularized across Eurasia. The specific geographic setting makes Hexi Corridor in northwestern China one key regions to converge various types crops livestock, witness deep impact novel species on local subsistence. Archeological evidence reveals emergence early oriental-occidental communication at opening Bronze Age Corridor, resulting a significant shift However, due lack more detailed archeological evidence, initial timing trajectory transformation livestock feeding patterns remain unclear. In this study, we reported systematic stable isotope precise radiocarbon dating analyses faunal remains unearthed from Huoshiliang Ganggangwa, two Early settlements ( ca . 4,000–3,700 BP) middle Corridor. Our results show distinct diversification ∼3,850 cal BP; contrast previous periods, some omnivorous appear have consumed mainly C 3 foodstuff herbivorous primarily 4 plants. Combined published data other findings neighboring region, clearer evolution revealed diversified strategy amid during We argued that alteration pattern reflects attempt achieve efficient economy sustainable society, order withstand harsh arid environment
