Northeast China was not the place for the origin of the Northern Microblade Industry: A comment on
Abstract Yue et al. (2021) have proposed a model of two Upper Palaeolithic industries in Northeast China called the “Initial Microblade Industry” and the “Northern Microblade Industry”, with the latter originating from the former, and its spread to the neighbouring regions of Northeast Asia. We have found several inconsistencies in their factual data and methodology, and therefore the conclusions reached by Yue et al. (2021) cannot be accepted at face value. Using the most reliable evidence, the oldest true microblade assemblages are known from the Korean Peninsula. We suggest that this region is the more probable centre of diffusion of microblade technology in mainland Northeast Asia, including China and the Russian Far East.
