Scientists Found a 2,300-Year-Old Skeleton. It Solved the Mystery of ********* Ancestry.

“Hearst Magazines and Yahoo may earn commission or revenue on some items through these links.”

A research team from the University of Tokyo analyzed DNA from a Yayoi-******* skeleton to determine the ancestral makeup of the modern ********* population.

The unique DNA makeup found in the bones matches that of a people group from the Korean Peninsula mixing with native Jomon people.

The influx of Korean Peninsula immigrants to Japan probably led to a significant culture shift on the island country.

Scientists from the University of Tokyo may have just ***** to rest a long-standing debate over the ancestral origins of the modern ********* population. By analyzing the DNA of a 2,300-year-old

, the team was able to learn that ********* ancestry is a mix of two people groups that integrated during the Yayoi ******* (around 300 B.C. to 300 A.D.).

This analysis was no small thing—in fact, the investigation required a full nuclear genome analysis of a skeleton found in 1952 at the Doigahama ruins in

. Once completed, the results suggested that “between the Yayoi and Kofun periods, the majority of immigrants to the ********* archipelago originated primarily from the Korean Peninsula,” the research team wrote in a study

in the Journal of Human Genetics.

A full-scale understanding of ********* ancestral history has been limited, the authors explained, largely because of a lack of access to Yayoi-******* ********. But in 1952, a construction project uncovered about 300 Yayoi-era human

at the Doigahama ruins, and the find led scholars to split in their hypotheses regarding the hearly genetic makeup of the ********* people group. This new information led some experts to develop a dual-structure model—mixing two people groups together—of the modern ********* genetic makeup, while others stuck to a triple-structure model.

In this new study, the team explained that a comprehensive genetic analysis of the Yayoi individual whose bones were examined (along with comparisons to people groups across both East and Northeast Asia) revealed that the bones did have three distinct genetic ancestries. But the best match for that ancestry came not from three different people groups, but from mixing the

composition of modern Koreans (which is itself comprised of both East and Northeast ****** ancestries) with the genetic compostion of the Jomon people.

So, the authors had their answer: the genetic composition of the modern ********* people is a blend of the Jomon people and the modern Koreans. And those immigrants arriving from the Korean peninsula during the Yayoi ******* would have brought much more than just their genes—they likely also brought new
