TL;DR: The history of cultural exchange in prehistoric Eurasia (CEPE) has been widely investigated as mentioned in this paper, and it is likely that CEPE promoted the spread and exchange of crops that originated in different parts of Eurasia; since these remains can be definitely identified and directly dated, they provide ideal research materials to explore the history of CPE.

TL;DR: In this article, the authors report dozens of direct radiocarbon dates on charred grains from 22 archaeological sites of the Neolithic and Bronze Ages in the Hexi Corridor, northwest China, a key region for trans-Eurasian exchange in prehistoric and historical times.

TL;DR: Wang et al. as mentioned in this paper analyzed carbon isotope analysis of human, pig and dog bones, and radiocarbon dates from Neolithic sites, and compared them with black carbon content from palaeoenvironment records in northern China, in order to explore the temporal-spatial intensification and expansion of millet-based agriculture in the area and its possible impact on environment.

TL;DR: This paper found that local foragers continued to hunt but supplemented their diet with agricultural products in the form of millet, rather than being grown locally, this millet was acquired via exchange with farmers, highlighting how indigenous foragers engaged in complex patterns of material and cultural exchange through encounters with newly arrived farmers.
