Reply to Bourguignon et al.: Convergence is a plausible hypothesis for Quina technology in East Asia
Bourguignon et al.’s claim that we do not discuss taphonomic process and surface alterations of the artifacts is incorrect. We demonstrated distinctions between microwear and natural and human-caused striations. There is no evidence of size-related sorting, no preferential orientation pattern, and minimal to no inclination. These data support the interpretation that the assemblage from Layer 3 reflects a spatial distribution pattern consistent with in situ deposition. Overall, our report of Quina technology contributes to evidence to the growing recognition of technological diversity and human dynamics within East Asia.
