The researchers rewrote Japanese history after discovering a third ancestral group, and previously unknown, migrated to Japan about 2,000 years ago, was the ancestor of today .0: 00/3: 35 Southern state of ancient bones discovered the third ancestral of Japanese people today. Ancient multistribution can be divided into three important periods: Jomon period (13,000 to 300 years ago raw), the period where a small group of hunters gather proficiently about independent live pottery on the island; Yayoi period (900 BC to 300 years after Cong Phu), when farmers migrate to Japan from East Asia and agricultural development; And the Kofun period (300 to 700 years of BC), when Japan today begins to form. The previous research has shown two major genetic origins of today's Japanese population are hunters. Originally lived in the period of Jomon and farmers migrated to Japan during the Yayoi period
. The researchers said, in a recent study, the ADN analysis was found from an ancient skeleton Revealed the third genetic origin in the Kofun period, when an unknown ancestral group previously migrated to Japan.Shigeki Nakagome, Assistant Professor School in Trinity College Dublin in Ireland, said: "We believe our research clearly demonstrates the power of ancient genes in discovering new ancestral components that cannot only see from modern data." A person who came from the middle National and South Korea? Jomon gathering hunters may have appeared for the first time in Japan at about 20,000 years ago and maintained a qu Small citizens of about 1,000 individuals for thousands of years
Researchers said in a statement with evidence of people living in Japan 38,000 years ago, during the old stone period, but few people knew about these people. "A long-term hypothesis said they As an ancestor of Jomon, "Nakagome said. This means that people belonging to the old stone stones may have transformed into Jomon in about 16,000 years ago, he added. Other explanations may be Jomon people originating from East Asia and crossing Korean Strait When it was covered by tape during the last hour of the last ice - the last time during the last ice period when the iceberg was the largest level - about 28,000 years ago.Nakagome said: "However, whether these hypotheses are true or not yet known due to the lack of the old stone genome from Japan." At the beginning of the Yayoi period, there was a line of people from China or South Korea Agricultural experience. These people have introduced agriculture into Japan, resulting in the development of the first social class and the landlord concept. Yayoi period turned into the Kofun period, in which the first political leaders first Appears and a single country, later becoming Japan today, formed. However, so far, it is unclear whether the transition of Kofun is the result of a third series migration or just the natural continuation of the Yayoi period. East Asia origin of the Japanese New, Nakagome and his team analyzed genes of 12 individuals from all over Japan
Nakagome said: 9 genes of the Jomon-belonging person and 3 genes of the Kofun period. The results showed that a third Japanese ancestral group was genetically migrated to the country Hey during the Kofun period. The ancestors of these people from East Asia and most likely Han people from ancient China. "The archaeological evidence has long suggested three phases of migration, but the last phase is mostly skip." Mikael Adolphson, Japanese history professor at Cambridge University, said that findings also show that most genes in the Japanese population today are derived from East Asia, undergoing three main periods of progress Mixing Gene.Nakagome and his team are very happy to help confirm a new part of Japan and hope these findings can open the door for deeper discoveries.
