ORIGINES AND AFFINITIES OF DIPERSAL POPULATIONS (PHYSICAL ANTHROPOLOGY)

1. 在爪哇和中国的直立人头骨中发现了几个蒙古人种特征。这表明蒙古人种起源于亚洲。绳纹人与弥生人在颅骨非同源性状的发生模式上存在较大差异，但弥生人时期之后，在日本中部诸岛，这种性状的表达在过去2000年里保持了相当稳定。这有力地支持了关于现代日语起源的迁移理论。在亚洲和美洲蒙古人种中观察到相同的hla -单倍型。这表明亚洲蒙古人种迁移到了美洲。hla -单倍型在日本各地区的分布格局表明，过去曾有过从亚洲大陆到日本列岛的多次迁徙。基于12个遗传多态性位点，对30个世界群体进行了遗传关系分析。从这个结果来看，密克罗尼西亚人、波利尼西亚人、甚至澳大利亚土著人以及美洲人显然是从东亚/东南亚分散开来的。

1. Several mongoloid features were recognized in the skulls of Homo erectus from Java and China. This suggests that the Mongoloid originated in Asia.2. In the incidence pattern of cranial nonmetic traits, there is a great difference between the native Jomon and immigrant Yayoi, but after the Yayoi period the trait expression has remained quite stable during the last 2000 years in the central islands of Japan. This strongly supports the migration theory as to the origin of modern Japanese.3. The same HLA-haplotypes were observed in the Asian and American mongoloid peoples. This suggests that the Asian Mongoloid moved to Americas. The distibution pattern of HLA-haplotypes in various areas of japan indicates that there were several migrations from the Asian continent into the Japanese islands in the past.4. Genetic relationships were examined for 30 worldwide populations based on 12 loci of genetic polymorphism. From this result it became obvious that the Micronesian, Polynesian and even the Australian Aborigenes as well as the Amerindo dispersed from East/South Easat Asia.
