The ridges of a cusp, omprising a central ridge and the mesial and distal accessory ridges, were identified by the patterns of the moire fringes. The central ridge was present on all cusps except for the hypocone in both sexes. Frequencies of the two accessory ridges on trigonal cusps exceeded 60% except for the distal accessory ridge on the etacone. The mesial accessory ridge on the metacone was significantly more common in females than in males, but the running pattern of the cuspal ridges showed little difference between sexes. The oblique ridge of the deciduous molar was well developed compared with that of the permanent first molar. This ridge was observed in all subjects, but its height and structural components varied remarkably. A small tubercle on the oblique ridge was sometimes observed, usually located on the metacone side. This tubercle was similar to the metaconule in its position and morphology. Intercuspal distances showed larger mean values in the molars with a metaconule than those without. This implied that the overall crown size was affected by the degree of development of some crown components, such as the ridges and tubercles.","PeriodicalId":84964,"journal":{"name":"Jinruigaku zasshi = The Journal of the Anthropological Society of Nihon","volume":"98 1","pages":"39-47"},"PeriodicalIF":0.0,"publicationDate":"1990-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67046436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As early as 30, 000-40, 000 years B. P., the ancestral \"Proto-Australoid\" of Southeast Asia might have moved into Wallacea as well as Sahulland and evolved under the particular selective forces. In the tropical rain-forest of Sundaland, this \"Proto-Australoid\" might have evolved into the \"Proto-Malay\", one of whose descendants might be modern Negritos of the Philippines. On the other hand, a late Pleistocene population occupying the Sundaland was probably the direct ancestor of the Proto-Mongoloid population, which might be the lineage leading to the Neolithic Jomon population and modern Ainu. The final populating of the Pacific was by Polynesians and Micronesians extending from Southeast Asia.The population history described above emphasizes the necessity of broad comparisons and investigations in studies on the origin and affinities of modern Japanese. In this study, the dental measurements of some geographically isolated populations in Japan whose ancestors could be traced back to the Southeast Asian Proto-Mongoloid population were compared with those of the Neolithic Jomon population, Negritos, Australian Aborigines, Polynesians, Micronesians, and Melanesians.The results obtained indicate that there may be a dichotomous relationship between Japanese and the Pacific populations (Micronesians and Polynesians). The dental characteristics of Negritos have something in common with those of the two population groups. The basic population of native Japanese are discussed based on such findings.","PeriodicalId":84964,"journal":{"name":"Jinruigaku zasshi = The Journal of the Anthropological Society of Nihon","volume":"98 1","pages":"13-27"},"PeriodicalIF":0.0,"publicationDate":"1990-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1537/ASE1911.98.13","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67045708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the newly devised 'bipedal training box', in which rats achieved a fully upright stance through positively reinforced operant conditioning, the exercise group was burdened with the bipedal standing exercise from 64 days to 140 days of age, totally in 136-138 sessions. At the age of 140 days, the left femur was dissected out, ten serial cross sections of the femoral diaphysis were cut from proximal to distal and cross-sectional properties were calculated from the photographs of the sections. The bipedal standing exercise had the following effects on the femoral diaphysis; an increase in the cross-sectional area, area moments of inertia in the proximal half of the shaft, i.e. the strength of the femoral diaphysis increased against axial compressive, antero-posterior bending and medio-lateral bending, respectively; an increase in the polar moment of inertia and an external rotation of the principal axis in the vicinity of mid-shaft, i.e. the strength against the torsional load increased and the direction to resist the maximum bending load more or less approached the antero-posterior direction. These observations were discussed in comparison with the effects of quadrupedal running exercise on the femoral cross section previously observed by us.","PeriodicalId":84964,"journal":{"name":"Jinruigaku zasshi = The Journal of the Anthropological Society of Nihon","volume":"98 1","pages":"451-470"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67046518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
