近日，一项综合了语言、基因和考古学证据的研究发现，包括现代日语、韩语、土耳其语和蒙古语等同一语系的语言以及说这些语言的人，都起源于大约9000年前生活在中国东北地区种植谷子的古代农民。

Origins of Japanese and Turkish language family traced back 9000 years

A vast Transeurasian language family that contains the Japanese, Korean, Mongolian, Turkish and Tungusic languages has had its origins traced back 9000 years, to early farming communities in what is now north-east China.
Transeurasian languages are spoken across a wide region of Europe and northern Asia. Until now, researchers assumed that they had spread from the mountains of Mongolia 3000 years ago, spoken by horse-riding nomads who kept livestock but didn’t farm crops.
