This paper introduces a "dual structure model" that explains the population history of the Japanese population including the Okinawa islanders (Ryukyus) and Ainu under a single hypothesis. The model assumes that the first occupants of the Japanese Archipelago came from somewhere in Southeast Asia in the Upper Palaeolithic age and gave rise to the people in(More)
This study has been carried out to assess the age from the pubic symphysial surface employing a multiple regression analysis and a quantification theory model I analysis. Using partial regression coefficients and/or normalized scores obtained from the analyses, ages of skeletal remains can be quantitatively estimated with a fairly high reliability. The use(More)
Excavated bones (rib) obtained from 50 sites in Japan were measured by ICP atomic emission spectrometry and atomic absorption spectrometry for concentration of 19 elements, including Al, B, Ca, Cd, Cr, Co, Cu, Fe, K, Mg, Mn, Na, Ni, P, Pb, Sr, Ti, V and Zn. One hundred and forty-one specimens were classified into five groups according to Japanese(More)
The origins and affinities of Japanese were analysed by means of cluster analysis using nine cranial measurements which were statistically selected as those representing a large proportion of the variance. As a result, the following hypotheses are proposed: Japanese are basically descendants of Jomon people, a fairly large amount of admixture between(More)
Nineteen elements (Al, B, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, Pb, Sr, Ti, V and Zn) were analyzed in excavated bone (rib) of the Edo era (a Japanese historical era, 300-120 BP (before present] from different burial conditions in Tokyo, and in contemporary Japanese bone (rib) obtained from autopsy cases. The elemental composition of the excavated(More)
Crown morphology of 85 plaster dental casts from skeletal and living Ainus of less than 1/8 non-Ainu admixture is described and compared for microevolutionary and origins considerations. There is no significant sex dimorphism and few inter-sample differences through time. Inter-observer differences occur where observation standards are poorly established.(More)
