What Scientists Uncovered Will Shock You | Ancient Korean Genes Hold a Surprising Secret

Recent DNA analysis has revealed something truly unexpected, a genetic link that could rewrite what we know about Korea's past.What if the roots of Korea’s most influential dynasties go deeper than we ever imagined, stretching back to a mysterious ancestry long thought extinct? This discovery is set to change everything.Japan's genetic history has been well-studied. Ancient remains from the Korean peninsula, however, were largely unsampled until 2022.Thankfully, scientists have changed that. They sequenced ancient genomes from southern Gyeongsang and Gunsan-si in South Korea. These results are intriguing.They will especially interest those fascinated by ancient East Asian hunter-gatherers and their genetic legacy.
During Korea's Three Kingdoms period, Baekje, Silla, and Goguryeo fought for dominance. The Gaya confederacy, consisting of smaller kingdoms, was caught in the middle.Gaya was eventually absorbed by Silla, along with Baekje and Goguryeo.So far, ancient DNA has been retrieved only from Baekje's southwestern territory and the Gaya confederacy's south-central area.

I am Korean. It seems to be very sophisticated content. There are too many weird comments that are unrelated to mainstream academic content, but I hope you stay strong. It’s really great content!!

Even if You lived in Japan for a long time, he would not know that the first emperor of Japan was a descendant of the royal family of Baekje, one of the countries on the Korean Peninsula, because it is taboo in Japan.  As someone who studies East Asian history, I would like to briefly explain the relationship between Japan and Korea. Japan was a blessed island nation that accepted many cultures from China (mainly the Tang Dynasty) and the Korean Peninsula (mainly Baekje and Gaya) and was not invaded by continental powers.Even the only Mongol invasion failed by storm ("kamikaze" as the Japanese call it).Historically, Korea people fought many great wars in which hundreds of thousands or millions of troops invaded, but the targets were northern people groups such as the Sui, Tang, Khitan, Qing, and Mongols, and were generally friendly to the Chinese dynasties of Song and Ming etc... onJapanese archipelago, which had been dormant and isolated from civilization until the 1500s, awakened with reforms and openness from the West, and how Koreans, who had considered themselves culturally and militarily superior, suffered great hardships at the hands of Japan until the early 1900s.The background of this great war(Imjin War, Seven years War, The Bunroku Keicho War) that took place in 1592 is that the carelessness and arrogance of Joseon (Korea), which enjoyed only peace and culture for 200 years, treated Yamato (Japan) as a barbaric pirate group rather than a country. However, Yamato had a high level of tactics through clan battles for 100 years, and the 170, 000 troops of Toyotomi, who unified the whole country, armed with Portuguese matchlocks and attacked Joseon.Historically, Japan has waged a surprise war without a declaration of war.The 16, 000 Elite heavy cavalry that Joseon was proud of, which had suppressed the cruel northern peoples, was defeated by the Yamato  Matchlock unit, and 70, 000 Joseon Main Forces was pushed back all the way to Pyongyang. Yamato, which was a medieval feudal lord era, gained land and people if it won a war, but in Joseon, which was a  centralized country, the king fled to the north, but the people and monks formed a militia and fought to the end, the Japanese army was embarrassed by the existence of the Militia.Admiral Yi Sun-sin of Joseon defeated the Japanese navy by winning all 33 naval battles despite overwhelming odds.
  The basic weapons of the Joseon army were bows, spears, and swords, as well as gunpowder bombs and various cannons of different sizes..The Ming Dynasty (China) sent reinforcements to help Joseon, but instead harassed Joseon by plundering and engaging in internal communication with Japan, but helped Yi Sun sin in the final naval battle.Yamato, who did not have the technology to make pottery, Taken in hundreds of Joseon pottery craftsmen to make pottery and exported the pottery to Europe, where it received favorable reviews.This Great war lasted for seven years and ended with Toyotomi's death.A quarter of Koreans were sacrificed in this terrible war, and in Japan, there is a grave of  head, ears, nose, a Korean civilian, as a record of the war.  This Great War was a symbolic event in which the international status of the Korean Peninsula with 4, 800 years of history was reversed by the Japanese archipelago with 1, 800 years of history.Two years after the end of the Imjin War, the famous Battle of Sekihara, took place in Japan. Joseon was unable to recover from the devastation of this terrible war for 300 years, and was invaded by the Manchus of the Qing Dynasty. It also suffered the humiliation of being brutally ruled for 35 years by Japan, which was armed with Western civilization while maintaining a policy of political strife and isolation..300 years later, Joseon became a reclusive country with a policy of isolation, and Japan defeated the Russian fleet through the strategy of Yi Sun-sin(T tactic, a modification of A cran's wing formation), the great naval admiral of the country it invaded 400 years ago, and later joined the ranks of the great powers.Yi Sun sin's the world's top 3 naval admiral and the turtle ship is an invincible Korean Item in the Age of Empires PC Games

This connection between ancient Japan and Korea isn't surprising, as Jomon style conical pottery was common in the Han River valley groups from the Neolithic Period, which later became Baekje, which helps explain not only the close relationship between Baekje and Wa (Japan) in later wars against Korguryo in the early historic period c3-400s AD, but also the preservation of Baekje Dynastic records in the Japanese Nihon shoki (c720AD).

I’m Japanese and my ancestors are Korean so we are brothers my Korean friends ❤

[yourthoughtsarenotyours]

In the history of Northeast Asia, Japan has always been a remote island nation on the edge of a continent, so the spread of idea and culture had to travel through the Silk Road to China, then Korea, and finally to Japan. Considering the slow speed of communication at the time, you can imagine how far behind Japan was in the introduction of the latest culture and civilisation. For example, Japan was unable to make proper pottery until the Imjin War, when potters were kidnapped from Joseon to Japan. There was even evidence and the emperor's own confession that the Japanese emperor was a descendant of Baekje, which existed on the Korean peninsula.
Given this historical context of the region, you can imagine Japan's inferiority complex about their ancient history that it's a civilisation founded by people who came through the Korean peninsula. During the 36 years of Japanese occupation, the Japanese burned documents about Korean history and tried to cover up as much of it as possible, especially as it related to Japan's ancient history. They even tried to rewrite history, saying that instead of Gaya passing to Japan and influencing the building of Japanese civilisation, it was the other way around, that Japan ruled Gaya.

Here is the research paper this video used

**All eight individuals are from the Korean Three Kingdoms period** (4th-7th century CE), during which there is archaeological evidence of extensive trade connections with both northern (modern-day China) and eastern (modern-day Japan) kingdoms. **All genomes are best modeled as an admixture between a northern-Chinese Iron Age genetic source** and a Japanese-Jomon-related ancestry


Overall, the **Korea-TK_1 and Korea-TK_2 individuals have a genomic composition that closely resembles Yellow River Bronze** and Iron Age individuals and Bronze Age Liao River populations.


the **TK period Korean population shared affinities with eastern Chinese populations. When compared to various present-day Asian populations, present-day Koreans and Han Chinese were the closest groups to Korea-TK_1 **

we observed once again that **Korea-TK_1 individuals were related to Bronze Age populations from the Liao and Yellow rivers in Northern China.**

When we performed the same qpAdm modeling on an individual basis, we found that four of the six individuals in the Korea-TK_1 cluster could be modelled with a single source, typically Yellow_River-BA or Liao_River-BA, whereas individual AKG_10218, required between 4.0±1.8% and 7.3±4.4% ancestry related to either the Japanese Jomon or Ekven_IA, respectively, as a second source of ancestry

Interestingly, while the admixture pattern for the genome of individual AKG_10218, a male, was not different from the models for the Korea-TK_1 individuals, the pattern for his X chromosome SNPs was one that matched a northern Chinese maternal ancestry and lacks the Siberian ancestry associated with Devils_Gate genomes (Fig. S18). This result suggests a differential origin of both parents which is the outcome of an admixture in the region during the TK period.

The genetic diversity seen among the Gimhae TK period individuals can be explained by at least two scenarios. One is that the Jomon ancestry observed in Korea-TK_2 is the result of a regional admixture that occurred gradually within the Korean peninsula between at least two subpopulations where the indigenous population already carried the genomic components prominent among Jomon people. There is indeed some evidence of Jomon existence in the Korean peninsula along the Southeastern coastline supported by the artefacts such as pottery and obsidian arrowheads. The obsidian is recognized as an import from Kyushu in Japan (43), however such evidence dates to the Neolithic (10000-1500 BCE), a rather distant history. Moreover, Jomon has not been identified as a dominant cultural component in this area, which could imply that individuals bearing Jomon-related ancestry were either completely absorbed by populations originating from northern China, who entered along the Korean peninsula coastlines, or their genetic signal was diluted by various other demographic scenarios, leading to the genetic homogeneity observed in present-day Koreans.


Diploid calls analyses.
A) fineSTRUCTURE. The plot shows that Korea-TK_2 clusters with Japanese and IK002_Jomon individuals, while Korea-TK_1 shows connections with Han Chinese and Korean individuals. B) Shared IBD segments (>1 cM). Korea-TK_2 shows the highest number of shared IBD with Japanese, while Korea-TK_1 shows connections with both Koreans and Japanese. C) IBD shared among the pairs of TK individuals; even though none of the pairs indicate familial relationship, it shows the highest IBD sharing between the TK_2 individuals, namely AKG_10203 and AKG_10207.

Have heard that there was a DNA link between Koreans and some tribes in the Americas. I wouldn’t be surprised if that connection precedes the time of Peleg.

Hmmm I always wondered why my dad could grow a full beard and lacked the epicanthic folds. As far as I know I am 100% Korean. He was from Kyongju though.

The earliest findings of the neolithic Korea are around 8, 000~7, 000 years ago. It makes sense that the Korean/Tushima strait was only formed around 10, 000 years ago when the warm current had started penetrating into the Yellow Sea and the Sea of Japan to warm up the regions (it will take thousands of years for southern vegetations to spread and settle). Before then, the residues of the last Ice Age were strong and Korea was very cold and arid making human hard to survive without significant trees/nuts/animals. The upward Jomon migration into Korea makes more sense if much of Jomon themselves came from the south.

[chappy]

Very interesting. More videos about Koreans in the future please

[jjn]

Makes sense that Jomon people are an ancient population also found in southern Korea. Given that the land mass was a single, connected mass between modern Korea and Japan during the ice age, they probably thrived there. Even with retreating ice and rising sea level, the distance was and still is navigable and passable.

I already mentioned the issue of correlation between 'Jeulmun Pottery' and 'Jomon Pottery
in another comment of mine.
Here, I would like to touch on the matter of the Mumun Pottery Period very briefly.

The beginning of the Mumun Pottery Period (無文土器時代) almost coincides with the
beginning of wet paddy rice agriculture in Korea.
From this, it is possible that the people who introduced rice cultivation, which originated
from the Yangtze River civilization (長江文明), to the Korean Peninsula had brought
Mumun pottery as well.

Now, Dr. Mitsuru Sakitani (崎谷満), director of the Institute CCC, suggests that
"the people with Y chromosome haplogroup O1b (O1b1 & O1b2) were the bearers
of the Yangtze River civilization.
Of these, it is thought that O1b1 was allocated by Yue people (越人), and O1b2
by Wu people (呉人), while O1a was distributed by Chu people (楚人).
With the decline of the Yangtze civilization, people with O1b1 and some O1b2 moved
south, and came to be called Baiyue (百越).
Further, he deduces that ”the people with the remaining O1b2 migrated either westward
or northward, reaching the Shandong Peninsula (山東半島), the Korean Peninsula, and
the Japanese archipelago.
This suggests that the people who brought Mumun Pottery to Korea and Japan belonged
to the O1b2 lineage."

Indeed, recent genetic survey shows that O1b2 can be observed in about 30% (20-40%)
of the current Korean population, and around 35% (30−40％) of the modern Japanese
people.
Having said that, the type of O1b2 in the Korean people is 'L682, ' whereas the one in
Japanese people 'O-47z.'

Either way, Dr. Sakitani's analysis that "people from the areas along Yangtze River basin
brought Mumun pottery together with wet paddy rice farming to both Korea and Japan”
has got a point to a certain degree, it seems.

[vidya]

Is it really that much of a shock to find Jomons in parts of Korea? Especially the south? Jomons didn't just pop up from the ground in Japan and/or just stayed there lol.

[angloedu]

One common trait that all East Asians have is the Mongolian Purple Blue “Birthmark”. Some Caucasian people have this Mark as well, especially Caucasians from the Balkans and parts of European Ukraine.

The other common trait that geneticists know of, but academics keep quiet on are the common trait between Koreans, Japanese, and Nordic Scandinavian people, they have dry, white ear wax. It’s been known of since the early 1900’s but often dismissed but a common character amongst Northern Arctic and Siberian climate people.

Occam's Razor: Some Koreans simply expanded beyond the peninsula. ex) Baekjae after being expelled from the peninsula after losing war

Fascinating, I’m so glad to hear this. I wish there was more info on the peopling of Asia
