摘　　要：The innovations of agricultural production and their extensive dispersal promoted the transformation of human livelihoods and profoundly influenced the evolution of human-land relationships in late prehistoric Eurasia.The Steppe and Silk Roads(SSRs)played important roles in the transcontinental exchange and dispersal of cereal crops and livestock related to agricultural innovation across Eurasia before the Han Dynasty(202 BC to AD 220),while the geographical-temporal variations in prehistoric subsistence in relation to the spread and exchange of cereal crops and livestock originating from different areas of Eurasia still remain unclear.In this paper,we explore these issues based on the review and analysis of published archaeobotanical,zooarchaeological,and carbon-stable isotope data from human bones from Neolithic-Early Iron Age sites in areas along the SSRs,with a comparison to updated results based on radiocarbon dating and ancient DNA analyses.Our results suggest that humans engaged in hunting game,while foxtail/broomcorn millet cultivation gradually became the primary subsistence strategy in Eastern SSRs from 10,500 to 6000 a BP.In contemporaneous Western SSRs,humans mainly cultivated wheat/barley and raised sheep/goats,cattle,and pigs.Trans-Eurasian exchange,which is reflected by the mixed utilization of wheat/barley and millet,emerged in the south-central Steppe during 6000–4000 a BP,while millet cultivation and pig husbandry became the dominant livelihoods in most areas of Eastern SSRs.During 4000–2200 a BP,Silk Roads became the major passageway for trans-Eurasian exchange,the interactive development of oasis agriculture and pastoralism facilitated intensive human settlement in the Central Silk Roads,and subsistence strategies substantially changed with significant geographical differences in Eastern SSRs,while subsistence in some areas of Western SSRs was evidently affected by the introduction and adoption of millet crops after 3000 a BP.The geographical-temporal variations in subsistence in the SSRs
