The evidence seems fairly strong that the proto-culture and the majority of the ancestors of Japanese and Korean people originated together near Inner Mongolia, thousands of years ago. This was a separate and distinct culture from the proto-Chinese culture which at the time had already been in existence further south. Of course, there have been both cultural and genetic interactions between Chinese and Korean/Japanese and the later split groups of Koreanic and Japonic people for thousands of years, so these have never been completely separate, isolated populations. But the idea that Japanese and Koreans were “once Chinese” doesn’t really seem to comport with the evidence. Obviously at some time even earlier, however, all three groups likely branched off from a common migration from the west, long ago in prehistory.

有相當強的證據(jù)表明,日本人和韓國人的原始文化和大部分祖先起源于幾千年前的內(nèi)蒙古附近。這是一個與當時已經(jīng)存在于更南方的原始中國文化相分離且獨特的文化。當然,中國人與韓國人/日本人之間存在著文化和基因的互動,以及朝鮮語系和日本語系人群的歷史交織,因此它們從未完全分離、孤立的群體。但是,認為日本人和韓國人"曾經(jīng)是中國人"的觀點似乎與證據(jù)不符。顯然,在更早的時候,這三個群體很可能都源自一個共同的來自西方的遷徙,遠在史前時期。
