Abstract
Unearthed artifacts and cultural relics from the Shuidonggou site revealed extensive information and insights regarding the activities of early modern humans. A series of experimental research and physical analysis suggest that stone artifacts from Locality 2 and Locality 12 have undergone heat treatment. The utilization ratio and knapping properties of raw materials were consequently enhanced. Heat treatment technology reflects the production capacities and the survival strategies in the Upper Paleolithic period. This discovery indicates the earliest existence of this technology in the East Asia and thus confirms a wider geographic distribution of this technology which provides new perspectives and evidence for understanding the associated early modern human behaviors.
