  • East Asians show Similarity between Stone Age and Modern Populations
 

East Asians have shown similarity between their ancient and modern populations as is evident from the DNA analysis.

Ancient DNA samples were taken from the relics left behind of East Asian populations in a Russian grotto. The stuff we are talking about is 8000 years old.

The genetic profiles of modern-day East Asians closely resembled these ancient relics showing the level of continuity between the two. What this shows us is that for a period of many millennia, there were no changes in the DNA traits of this particular population. 

Therefore contemporary East Asians and several other ethnic varieties share a common genetic background with their ancestors who roamed the earth in hunter-gatherer times.

Yet this is especially so in case of East Asians rather than Western Europeans. In the case of the latter, the early farmers were overtaken by a wave of hunter-gatherers.

Also horse-riders from Central Asia came in wave after wave in the region during the Bronze Age. Agriculture and metallurgy played their roles in these advancements. However, in parts of East Asia, the story unfolded in a different manner.  

The historic gap in no way affected the genetic continuity of the East Asians. The larger size of East Asia could have led to this passing on of the genetic heritage and absence of change.

While local miscegenation did occur, it remained limited to a select few instead of occurring in a vast majority. Wet rice farming eventually began in the region.

Korea, Japan and China showed this trend in quite a prominent way. Among the relics from which the DNA has been extracted may be included: stone and bone implements, carbonized wood and wild grass that has been woven into textiles.

The skulls of two females recovered from the grotto were especially helpful in the DNA analysis. The ancient remnants had to be sifted through to reach the truth.

The study was published in the journal Science Advances.
