Korean Nation's Origin Presumed by the Shape of Skull
It is known as 700 thousand years ago that the paleolithic people had started to live in Korean peninsula. Unfortunately, we have no skull fossil of those people that makes it impossible to compare them with ours.
We can study the morphologic features of skull fossils of 40 thousand years before, excavated from the relics of Yong-gok cave, Youk-pyo cave, Mt. Seungni cave, Mandal cave and Geumchon cave in North Korea and Sangsi Bawi Geuneul(that means the place under the shade of rock) and Hongsu cave in South Korea. According to the measuring of those excavated skull, they have different features with 'the skull of short length' of today's Korean as the frontal and occipital cranial length is longer than modern people and the cranial breadth-length index shows 'the skull of long length'. However, as the morphologic features that the cranial breadth-height index shows 'the skull of high height' and the facial breadth-height index shows 'the middle face' are appeared mixed, new kind of gene is estimated to have flowed into the Korean peninsula. The skulls were excavated from Hoi-ryoung and Ong-gi relics and the relation between the residents of New Stone and Bronze Age is still an issue of the academic world.
The completion of modern Korean's morphologic features is guessed to have been made up in Bronze Age. 'The skull of short length' and 'the skull of high height', the most important features of Korean skull had started to be formed since New Stone Age and completed in Bronze Age in which most people of the old Chosun had 'the skull of high height', and the genetic features have been inherited to modern people.
The origin of human beings and root of Korean nation could be resumed like this, compared with the results of studies of surrounding nations. Australopithecus, the ancestor of human beings, whose shape was Home erectus who lived in Africa, moved to the old World, leaving the African continent 1 million years ago and some divisions of them got to settle down in Java of Indonesia as Java people. The Java people also called as Pithecanthropus became the origin of Asian and Mongolian.
Part of Pithecanthropus moved toward North about 600 thousand years ago and reached in the Northern area of Chinese continent. Then some part of these became Sinanthropus and others moved to other areas of Asia and related to Homo sapiens later. Some division of the people who lived in the Northern area of China immigrated to Siberia and formed Northern Mongolian race who would have got several features like flat face and epicanthicfold because of the cold weather. Moving down to South in about B.C 5000 when the weather became warmer, the Northern Mogolian race who features long face, sparse eyebrows, small eyes, long nose and thin lips immigrated to the northeast Asia and so had a lot of genetic interchange with the existing residents in Korean peninsula.
Later those people who came to South went over to Japan and formed Yayoi. On the other, the Southern Mogolian who left in Indonesia with the features of squared face, thick eyebrows, big eyes with double eyelids, short nose and thick lips moved toward north along the coastline but about the time of the movement, when they partly influenced Korean figure, more studies should be done.
In conclusion, the people who have been living in Korean peninsula at the time of New Stone Age and Northern Mogolians are the foundation of Korean nation, and except these after that time the minority emigrants who moved to Manchuria area and adapted to Korean nation are proved only in studies of documents but whether they influenced Korean figure is not cleared up yet.
