Is the ancestor of the Japanese a Korean or a Korean, or a half-breed?

Japanese islands have been inhabited since the Neolithic Age. The earliest Japanese residents were Tungusic people who migrated from the northern mainland. Later, Malays crossed the sea from the south. Since the second half of 5000 BC, China and Koreans have been migrating to Japan. From the Neolithic Age to the 2nd century BC, Japan was called the Age of Rope Culture in archaeology. Stone tools and bone tools are used for hunting and fishing, and female earth dolls are unearthed in vertical caves (General History of the World, edited by People's Publishing House and Zhou Yiliang, 1962).

The oldest Japanese skeleton was found, belonging to the Ice Age about 20,000 to 30,000 years ago. It is generally believed that the rope literati first arrived in the Japanese archipelago during the Ice Age.

Compared with the physical objects all over the world, the genetic factors collected from the human bones of the rope literati are most similar to the ancestors of northern Siberia (but there are also genes from the south). Before the ice age, the climate in northern Siberia was warm and there were large animals and plants growing, but after the ice age, there was no trace of human life. Stone relics unique to Siberia, such as wedge-shaped stone cores, are found in northern Siberia, Sakhalin Island, Hokkaido and the Japanese archipelago. Therefore, it is generally believed that they lived in the Japanese archipelago from northern Siberia via Sakhalin Island and Hokkaido during the Ice Age.

During the ice age, the North Sea was covered with ice, so it was obviously feasible to move between Sakhalin Island, Hokkaido and the Japanese archipelago.

In addition, Austronesian, Vietnamese and Southwest Yi people brought Zhao Ye forest culture (burning cultivation culture) and rice from the lower reaches of the Yangtze River in China (Japanese bird Kenzaburo thinks that the Japanese are from Yunnan Dai, Yi and Hani, and visiting Chunxiong thinks that the Japanese are a Vietnamese).

Later, at the end of the rope and the beginning of the Yayoi period, new Mongolians (Yayoi people) migrated from Chinese mainland and Korea to the Japanese archipelago. Most Japanese in Kansai are descendants of Yayoi, while Kanto is descendants of rope literati (old Mongolian race), who have mixed blood for many times to form Japanese. However, people's physique and language were formed in 400 BC, and the real stereotype was that Xiayi surrendered after 12 century. Modern Japanese didn't really appear until the shogunate was overthrown (before the Japanese only admitted that they were vassal members).
