In China, the earliest written record of alcohol appeared in oracle-bone inscriptions around 3000 years ago. Archaeological investigations, however, have pushed back the date of alcohol production several millennia. Around 9000-8000 years ago, the production of fermented beverages in specialized pottery vessels appeared as a significant component in the transition to agriculture. Since then, alcohol has been essential in ritual feasting, contributing to sociopolitical processes throughout prehistory and history. Our research has revolutionized the understanding of alcohol production and consumption in the prehistoric Yellow River valley.

China is one of the few centers in the world where plant domestication evolved independently, but its developmental trajectory is not sufficiently understood. This is partly because there is considerably less data on macrobotanical remains from the terminal Pleistocene and early Holocene documented in China than in other regions, such as the Near East. To resolve these problems we have employed use-wear, starch and phytolith analyses on stone tools (grinding stones and cutting tools) to recover evidence for plant use. We have conducted several projects to investigate the range of plants used by Upper Paleolithic hunter-gatherers, as well as by early Neolithic farmers who cultivated millets in the Yellow and Liao river valleys and rice in the Yangzi River region.
Our data show a long history of broad-subsistence strategies, including exploitation of diverse plants, tracing to the Upper Paleolithic 28,000 years ago. This subsistence practice continued to the early Neolithic, despite the emergence of agriculture. We have recently expanded our research to the Yin Mountains in Inner Mongolia, where newly discovered Neolithic sites show a transition to early sedentism and millet cultivation more than 8000 years ago.
