Who played the Major Role of Agricultural Culture in Yayoi Period? - Agent based Simulation to Anthropological and Archaeological Problems -

Abstract

In anthropological and archaeological problems, it is difficult to presume the change processes among specific time points when ruins were excavated. In this paper, we propose a novel Agent-Based Simulation (ABS) model to extract various to-be processes. As an example, we discuss the problem of whether native Jomon people or Chinese-Korean immigrants played the major role of agricultural culture in Yayoi period by ABS. The model demonstrates that under the situation where many Jomon people introduced the agricultural culture in early Yayoi period, it is possible that those who have the trait gene of Chinese-Korean immigrants belong to the largest group three hundred years later. This result suggests the plausibility that those who played the major role of the agricultural culture in early Yayoi period included many Jomon people and then the mixed breed people between Jomon and Chinese-Korean immigrants became to be those who played the major role. Compared with the other applications of ABS in archaeological domains, which only explain the simulation results and the archaeological facts based on the input data and models, our results utilize ABS as a novel tool to examine various to-be processes that could lead to new hypothesizes.
