| Outline of Final Research Achievements |
Mathematical modelling group (B02) had studied how modern humans expanded its range when archaic humans were present in Asia (Paleoasia) by using the method of modeling, analysis and simulation. We had developed and analyzed an ecocultural range expansion model, which assumes the interplay of cultural and population dynamics and ecological niche competition between modern and archaic humans. The analysis of the model had provided a hypothesis that explains how modern humans and Paleolithic technology had diffused into Europe and Asia. In order to perform mathematical analysis on archaeological database, we also developed several mathematical tools, including a new concept of "cultural spectrum". These methods will be applied to PaleoAsia DB, which has been collected by this project.

| Academic Significance and Societal Importance of the Research Achievements |
文化の伝播に着目して新人の拡散を研究するためには、考古学との連携が必須である。本プロジェクトで開発した生態文化的拡大モデルは、反応拡散系と呼ばれる数学の手法を、考古学的問題解決に用いたものであり、これによって強固な論理を持つ仮説を提示することができた。我々人間はどこから来たのか、我々とは遺伝子を指すのか文化なのか、このような問題を考える上で、絶滅人類が生息していた頃の我々の祖先を知ることは重要である。この問題に対し、数理科学的視点を持ち込み、文理融合分野できちんとした成果を上げたことは、学術的のみならず社会的意義も存在すると考えられる。
