The Late Pleistocene "Ushikawa man" from central Japan: Its Identity and Historical Reflections
「牛川人」は,1957年に愛知県豊橋市牛川町で発見され,中期更新世まで遡る「ヒト上腕骨」片として,鈴木尚と高井冬二が提唱した化石人類である。その後,帰属時代は後期更新世と改められたが,日本における人類化石の一例として認識されてきた。その一方で,特に1990年代以後はヒトの化石骨ではない可能性が指摘されてきた。しかし,何の動物骨のどの部位かは不明のまま近年に至っていた。本研究では,「牛川人」化石(上記の「上腕骨」破片と1959年に発見された大腿骨頭片)を比較形態学的に再評価し,双方ともがクマの骨格片との結論に至った。「牛川人」化石をヒグマとツキノワグマ標本24個体分について肉眼観察,ノギス計測,実体顕微鏡観察により比較した。また,「牛川人」化石と一部の比較標本についてCT撮影し,断面画像と3次元モデルを用いた比較所見を加えた。これらの観察結果から,クマ骨形態の個体変異を考慮のもと,牛川の「ヒト上腕骨」化石はクマの橈骨骨幹部の破片であり,大腿骨頭化石もまたクマ骨であると判定することができた。…
Periodontal disease in the Neolithic Jomon: Inter-site comparisons of inland and coastal areas in central Honshu, Japan
This paper examines periodontal disease as well as other oral health indicators of the Jomon population in order to understand variations in their lifestyle and their response to dietary diversity. The oral conditions of three Jomon populations in Late Jomon period are evaluated using two periodontal indicators, namely the distance measured between the cement–enamel junction to the alveolar crest (CEJ-AC distance), and the degree of inflammation …
Radiocarbon dating and carbon and nitrogen isotope analysis on human skeletal remains from Koh and Ikawazu sites of the Jomon period
本研究は,國府遺跡と伊川津遺跡から出土した縄文時代人骨の放射性炭素年代測定と炭素・窒素安定同位体比による食性解析を行った。國府人骨は,土器などの副葬品や抜歯風習などから,縄文時代前期と晩期の二つの時期に,伊川津人骨は晩期に帰属すると考えられてきた。この従来の年代推定を検証するとともに,食性の時代による変化や,抜歯型式に対応した食性の差違を調べることを目的とした。國府人骨は28個体について分析を行い,伊川津人骨は6個体について分析を行った。年代測定の結果,國府人骨は,5440–5990 cal BP, 4410–4520 cal BP, 2960–3070 cal BPの年代を示した。伊川津人骨は,2440–3070 cal BPの年代を示した。國府人骨の年代は,従来の前期と晩期という二つの時期の分類に加えて,一部中期の個体を含んでいる可能性を検出した。また,國府集団の食性は,陸上・淡水資源の摂取を特徴とし,晩期において淡水魚摂取の割合が下がっていた。伊川津集団の食性は,海産・陸上資源の摂…
Ancient mitochondrial DNA sequences of Jomon teeth samples from Sanganji, Tohoku district, Japan
We investigated mitochondrial DNA haplogroups of four Jomon individuals from the Sanganji shell mound in Fukushima, Tohoku district, Japan. Partial nucleotide sequences of the coding and control region of mitochondrial DNA were determined. The success rate of sequencing increased when we analyzed short DNA sequences. We identified haplogroups from all four samples that were analyzed; haplogroup frequencies were 50% (n = 2) for N9b and 50% (n = 2)…
Metric characteristics of human limb bones in Asian and Japanese populations
Twelve metric variables of the humerus, radius, femur, and tibia were investigated in 11 male samples from northeastern and eastern Asian populations. Variations among regions and correlations between latitude and respective measurements and indices were calculated and a principal component analysis was conducted to elucidate human limb bone characteristics. Significant correlation and marginally significant correlation were found for the maximum…
Comparative analysis of the glabellar region morphology of the late Pleistocene Minatogawa crania: A Three-Dimensional Approach
The Late Pleistocene human fossils recovered from the Minatogawa fissure in Okinawa Island are important in understanding the population history of the Japan archipelago. Based on high-resolution laser scanning, we conducted a three-dimensional (3-D) topographic evaluation of the glabellar and superciliary regions of the Minatogawa and Jomon crania. We aimed to address the question of whether the glabellar morphology of the Minatogawa crania can …
Accuracy and precision of CT-based endocranial capacity estimations: A comparison with the conventional millet seed method and application to the Minatogawa 1 skull
An increasing number of studies determine endocranial capacity (ECC) digitally using serial computed tomographic (CT) scan data. However, the multiple causes of errors inherent in such measurements and the resulting degree of accuracy have not yet been fully examined. In the present study, five observers estimated the ECCs of two modern human crania by segmentation of CT data (voxel size 0.380 mm) and by means of the conventional millet seed meth…
Chronology of the Yayoi skeletal remains from the Kanto district, Japan: A Preliminary Re-Evaluation by Radiocarbon Dating of Postcranial Material
Radiocarbon ages were determined for 25 samples of human skeletal remains previously assigned or attributable to the Yayoi period (tentatively considered ca. 500 BC to 300 AD) of the Kanto district, Japan. Suzuki (1969) and others, predominantly on cranial morphology, recognized that the Kanto Yayoi series contains three morphological groups: the native Jomon, transitional, and Kofun types. Morphological variation of the Kanto Yayoi people was co…
Vertebral assimilation in an adult male Ainu skeleton from the Tokoro Chashi site in Tokoro, Hokkaido, Japan
Vertebral assimilation was observed in an adult male Ainu skeleton from the Tokoro Chashi site of the early modern period in Tokoro, Hokkaido, Japan. The vertebral bodies and right zygapophyseal joint between the 12th thoracic and 1st lumbar vertebrae were completely united by osseous tissue, with anterior wedge shape and 42% loss of anterior vertebral body height. Differential diagnosis suggested that this was a healed state of pyogenic spondyli…
