日本人群的种族起源和演化

The Racial Origin and Evolvement of Japanese People

日本弥生时代人群的体质特征和比其早的绳文时代人群有很大的不同,他们之间可能不具有继承关系。本文主要根据体质人类学、遗传学和考古学的研究成果,阐述了日本不同时期人群的起源和演化。此外,还从中国考古遗址出土的古代人骨材料的研究,探讨了日本弥生时代人群的源乡。虽然现代日本人起源的"移民说"基本得到认可,但因古代人骨材料涉及的出土地点和时代有限,而且可能与日本弥生时代人起源有关的古代人骨DNA的研究结果也非常少;因此,从目前对中国大陆和日本弥生时代遗址出土人骨的对比分析结果看,关于弥生人源乡在哪里还无法得出一个明确的认识,还不能肯定地说出中国大陆的哪些古代人群对现代日本人种族形成有过重要的基因贡献。

Morphological features of the Yayoi people in Japan are very different from the Jomon people's.They two may not have direct inheritable linkage.The paper expound the origin and the evolvement of Japanese on basis of the research of Physical anthropology,Genetics and Archaeology.The paper also discussed the origin of the Yayoi people according to the ancient human skeletons in archaeological sites of China.We still can't get a clear opinion about where the Yayoi people originated though 'the immigrant theory' has been accepted by most students.We haven't enough evidence from archaeological human skeletons to show which specific ancient groups in China could be considered ancestors of the modern Japanese with important gene link.
