A groundbreaking study reveals that East Asia was inhabited by hominins with advanced tool-making skills equivalent to Mode 2 technology over 1.1 million years ago, challenging previous timelines and perceptions of early technological development in the region. This discovery, highlighting sophisticated techniques and planning, suggests a reevaluation of early human culture and connections across Eurasia. Slender flakes are intentionally broken and used as blanks for retouching tipped tools.
The study, which was conducted by a joint team led by Prof. PEI Shuwen from the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences and Prof.
In addition, patterns of retouching tools like points and borers, which showed standardization of tool shape, were also well documented in the Cenjiawan assemblage, thus suggesting complex mental templates among the Cenjiawan toolmakers.
“The advanced technological behaviors documented at the Cenjiawan site similar to those of Mode 2 technology, rather than the technical simplicity attributed to Mode 1”, said Dr. MA Dongdong, first author of the study, who conducted the research during his Ph.D at IVPP and currently is working as a postdoctoral researcher at the Institute of History of CISC.
