The research is the world’s first analysis on an ancient genome collected from East Asia, UNIST said.<br style="border: none;"><br style="border: none;">The research team compared the Devil’s Gate cavemen’s genome to those of multiple Asian modern day ethnic groups. Consequently, they discovered that a genome combination of the ancient Devil’s Gate cavemen and indigenous people of Vietnam and Taiwan best matched Koreans.<br style="border: none;"><br style="border: none;">Jong Bhak, a biomedical engineering professor at the Genomic Institute who led the research team, said Koreans’ genetic roots have been created from the mix of northern and southern Asian races.<br style="border: none;"><br style="border: none;">“This matches not only the migration of genes but also thousands of years of history,” he said. “This is biological evidence that definitely explains the creation of Koreans’ roots and the consequences.”<br style="border: none;"><br style="border: none;">Proportionally, actual genetic composition of modern Koreans is inclined to southern Asians because the people in the south thrived on agriculture compared to northern races that had mainly lived on hunting and gathering, he added.<br style="border: none;"><br style="border: none;">Bhak also said East Asians including Koreans had a greater internal identity compared to other ethnic groups worldwide.<br style="border: none;"><br style="border: none;">“The massive ethnic group including the Han race of China, Koreans and Japanese had such a high homogeneity,” the professor said. “This shows that they had exponentially expanded through the evolution of civilizations with agricultural technologies.”<br style="border: none;"><br style="border: none;">The research revealed that the humans who lived in the Devil’s Gate cave had genetic traits including brown eyes and shovel-shaped incisors, like Koreans. They also had typical genetic distinctions and variations of modern East Asians such as inability to digest milk, vulnerability to high blood pressure, relatively odorless bodies and dry earlobes.<br style="border: none;"><br style="border: none;">This shows that modern East Asians have better preserved genetic traces of their ancestors for thousands of years, compared to modern western Eurasians who have lost genetic signs of their ancestors through more migration and warfare, the research team said.<br style="border: none;"><br style="border: none;">“East Asians have preserved genetic continuity in each ethnic group without an inflow of outsiders for at least the last 8,000 years,” said Jeon Sung-won, a researcher at UNIST Genomic Institute.<br style="border: none;"><br style="border: none;">“Instead of conquering and eliminating other existing ethnic groups, people with revolutionary new technologies such as agriculture spread these and maintained lifestyles that fit in with regional nature.”<br style="border: none;"><br style="border: none;">According to the research, the humans who lived in the Devil’s Gate cave were the ancestors of the Ulchi people. As a minority race, they live in Far East Russia and spoke a Tungusic language. Except for the Ulchi people, Koreans turned out to have a similar mitochondrial genome type to ancient humans.<br style="border: none;"><br style="border: none;">“Having the same type of mitochondrial genome means having the same maternal line,” Jeon said. “We can say that the humans who lived in the Devil’s Gate cave were almost like the ancestors of Koreans.”<br style="border: none;"><br style="border: none;">The research has been published in the Feb. 1 edition of international scientific journal Science Advances, UNIST said.<br style="border: none;"><br style="border: none;"><hr style="margin: 0px; padding: 0px; border: none;"></div></div></div></div><p class="reporter" style="padding-right: 10px; border: none; list-style: none; text-align: right; font-size: 0.8em; font-family: Helvetica, arial, 'Malgun Gothic', '맑은 고딕', Gulim, 굴림, sans-serif; line-height: normal;">yoonsw@ktimes.com </p><p> </p>
