For Those Interested in Archaeology

"Japan has been inhabited by people since about 35,000 years ago. Roughly 16,500 years ago a group of Neolithic hunter-gatherers, referred to as the “Jomon” culture, developed a complex society including the production of pottery and jewellery.
About 3,000 years ago, rice cultivation in paddy fields was introduced to Japan. This saw the beginning of the Yayoi period which ended around the year 300 CE. After the Yayoi came the Kofun period (300–538 CE).
The new research, published in the Journal of Human Genetics, sought to understand the population dynamics behind this shift.
“There were various hypotheses to explain the history of the Japanese,” the authors write.
“For example, the ‘transformation model’ posits that only culture, not people, came from the continent. The ‘replacement model’ suggests a complete replacement of indigenous Jomon people by the Yayoi people, while the ‘hybridization model’ proposes admixture between indigenous Jomon people and continental immigrants.”"

The Chinese (some) think they weren't derived from Africans but i whole other group...
