     libri" size="3">By combining climate change data and archaeological discoveries, evidence shows that warm and wet conditions during the Holocene Climatic Optimum promoted the development of ancient cultures along the northeast ern margin of the Qinghai-Tibetan Plateau.

This included the formation of the Eastern Valley Majiayao Culture that coexisted with the Western Plateau Microlithic Cultures between 6 and 4 ka BP. The two coexisting culture systems participated in exchange during which the Weastern Plateau Microlithic Cultures obtained pottery, agriculture, and Neolithic technologies, promotinz their entrance into the Neolithic.
