Population history of the prehistoric southwestern Islands-An approach to elucidate the regional variations of morphological features.

本文试图从骨形态学、遗传学、年代学、生存学和考古学等方面阐明史前西南岛民的区域内差异。由于目前还没有在咲岛发现保存完好的史前遗骨，我们将研究重点放在了冲绳群岛。我们的史前骨骼遗迹和遗址数据库将有助于未来的调查。此外，在石垣岛白鹤- saonetabaru洞穴遗址发现的更新世遗骨有望对日本人口历史的研究做出贡献。

In the present research, we tried to elucidate the intra-regional differences of the prehistoric southwestern islanders from the viewpoints of osteo-morphology, genetic, chronology, subsistence, and archaeology. As the well-preserved prehistoric skeletal remains in the Sakishima Islands were not found by now, we performed the research focusing in the Okinawa Islands. Our database of prehistoric skeletal remains and sites will contribute to future investigations. In addition, new Pleistcene skeletal remains found at the Shiraho-Saonetabaru Cave site in Ishigaki Island are expected to contribute investigations of population history of the Japanese.
