Distance analyses were applied to 11 craniofacial measurements recorded in samples from East and Southeast Asia, Australia, Melanesia, Polynesia, and Micronesia for the purpose of assessing the biological affinities and possible origins of these populations. A clear separation between Australomelanesians and other populations from East and Southeast Asia and the Pacific is evident. The craniofacial variations suggest that the generalized Asian populations (Negritos, Dayaks, Lesser Sunda Islands, etc.) represent at least part of the morphological background of not only the majority of present Southeast Asians, but also the Neolithic Jomon people and their lineage in Japan, Polynesians, and western Micronesians. The original craniofacial features of Southeast Asians may have occurred as the result of convergent microevolution due to similar environmental conditions such as tropical rain forest. This supports the local-evolution hypothesis for modern Southeast Asian craniofacial features.
为了评估东亚和东南亚、澳大利亚、美拉尼西亚、波利尼西亚和密克罗尼西亚人群的生物学亲缘关系及可能的起源，对这些地区样本中记录的11项颅面测量数据进行了距离分析。澳大利亚美拉尼西亚人与东亚、东南亚及太平洋其他人群之间存在明显分化。颅面变异表明，广义的亚洲人群（尼格利陀人、达雅克人、小巽他群岛人等）不仅是当今大多数东南亚人的形态学背景的一部分，也是日本新石器时代绳文人及其后裔、波利尼西亚人和西密克罗尼西亚人的形态学背景的一部分。东南亚人最初的颅面特征可能是由于热带雨林等相似环境条件导致的趋同微进化的结果。这支持了现代东南亚颅面特征的本地进化假说。
