Outline of Final Research Achievements

Scattered human bone fragments unearthed from the Hinata cave in Yamagata Prefecture, Japan, were dated using the AMS method, and the morphology and mitochondrial DNA of those were analyzed. Most of the dated human bones from the Hinata cave were older than 10,000 years, with the oldest value being ca. 13000 years old. This date corresponds to the Incipient Jomon period. Although the Hinata cave human bones were fragmented, the morphological characteristics of the limb bone diaphysis were found to be similar to those of the Initial Jomon period. The haplogroup of mitochondrial DNA in the Hinata cave human bones seemed to be an ancestral type of the type found in Jomon population.

Academic Significance and Societal Importance of the Research Achievements

土器の利用開始は、人類社会にきわめて強いインパクトを与えた歴史上の一大イベントである。日本列島の縄文時代草創期(約16,000~11,500年前)は、世界的にかなり早い土器出現期であり、内外の研究者から多くの関心が寄せられてきたが、この時期の人骨は知られていなかった。本研究は、山形県日向洞穴から出土した人骨に草創期人骨が含まれていることを初めて明らかにし、その系統的位置づけを試みた。
