>Sept 17 (Reuters) - An analysis of ancient DNA is transforming the understanding of the genetic ancestry of Japan's modern-day population, identifying a crucial contribution from people who arrived about 1,700 years ago and helped revolutionize Japanese culture.
>Research published on Friday showed that the people of Japan bear genetic signatures from three ancient populations rather than just two as previously thought - a more complex ancestry for the archipelago nation of roughly 125 million.
>The researchers analyzed genetic information from 17 ancient Japanese people - DNA extracted from the bones of 12 specifically for this study and five done previously - and compared it to genomic data for modern Japanese people.
>Previously documented genetic contributions were confirmed from two ancient groups. The first was Japan's indigenous culture of hunter-gatherers dating to roughly 15,000 years ago, the start of what is called the Jomon period. The second was a population of Northeast Asian origins who arrived at about 900 BC, bringing wet-rice farming during the subsequent Yayoi period.
>Modern Japanese possess approximately 13% and 16% genetic ancestry from those two groups, respectively, the researchers determined.
